3-13-17/CC Re-Read – A few things popped out...

3-13-17/CC: STEPHEN WORSLEY (VP/Bus.Dev.)
“In the near-term, we are aggressively working to expand Avid’s client base, and in Q3 we signed another new client for a late-stage clinical product. We are currently in discussions with a number of prospective new clients, and we expect to sign addl. clients in the coming months.”
--------
Avid Revs FY17(fye 4-30-17) Guidance upped by +$10mm to $60-65mm. I went back 4 prior years – they’ve never failed to TOP the upper-ends of prior March Guidances. With Revs for 1st 3qtrs = (5.6 + 23.4 + 10.7) = $39.7mm, if they follow suit, Q4 Revs will be at least (65mm – 39.7) = $25mm. ...How close would that get us to Cash-Flow positive for Q4, should it happen? OP. CASH BURN for Q3(1-31-17) was: $6,274,000, and that's with Revs=$10.7mm at GM=26%.

CEO Steve King 3-13-17 AVID addendum: “We are currently on track to install 2 2,000-liter bioreactors in the facility within the next few months, with a book of business for the reactors already in place. We believe the total capacity potential of the facility, when operating in campaign mode, can exceed more than $75mm annually, bringing us to well over $100mm in total potential revenue between our 2 mfg. facilities, providing us with adequate capacity to continue Avid revenue growth through FY’18.”

3-13-17/CC: CFO PAUL LYTLE
“We have determined that it is not in the best interest of our stockholders to affect a reverse stock split prior to April 10, 2017. If our share price does not trade above $1 for 10 consecutive trading days by April 10th, we expect to receive a notice of delisting. If we received this notice, we will appeal this decision within the required 7 days and this appeal will stay any delisting actions by NASDAQ. At that point, NASDAQ will schedule a hearing, which is typically held within 45 days, and we will present our plan to regain compliance. We are considering several paths to regain compliance, including having addl. time to continue to allow the market to adjust, to reflect the current value of Avid as evidence with the recent movement in our share price. The hearing panel could afford us up to 180 addl. days to regain compliance, although this addl. time is not guaranteed and this decision is at the discretion of the NASDAQ’s hearing panel.”

= = = = = = = =”OTHER COLLABORATIONS FOR FUTURE CLINICAL STUDIES”
3-13-17/CC/S.King(Q&A): “While the initial Exosomes effort has been focused on ovarian cancer, we do have an interest in implementing this into all of our future clinical studies as a simple blood collection; so including potentially the NCCN studies, for instance, and other collaborations. But also there are sample sources of serum that we can obtain, as well as working with our collaborators at UTSW and Memorial Sloan Kettering to look at other tumor types.

WHAT OTHER CLINICAL COLLABS MIGHT SURFACE? Only AZN, or somebody else? If MSKCC/Dr. Wolchok runs future Clinical Trial(s), they will have to be Sponsored by somebody – who? Peregrine, or AZN/Collab, or some other Collab??

3-13-17/CC/JOE SHAN(Q&A): “There are SUNRISE patients still, as we mentioned, still receiving bavituximab, so that gives you an indication that there are patients that are not only, what we call long-term survivors but there are diseases that stabilized. That’s why it's was important that the trial is formally concluded that we allow the patients the opportunity to continue receiving bavituximab under COMPASSIONATE USE. The biomarker analysis is still ongoing, and we’re also hoping to wrap that up in the next few months. Those data will be presented as they’re become available, but the first observation that we’ve reported on already, we mentioned the correlation between beta-2glycoprotein-1 [B2GPI] levels, which is an important protein for bavituximab to bind, so that’s important confirmation of a biomarker for drug activity. And, like I mentioned, there will be a presentation on other cytokine biomarker, interferon gamma [IFN-y], in about 2 weeks time [4-3-17 AACR’17 http://tinyurl.com/zzldh9n ]. Regarding the COMPASSIONATE USE, the procedure varies from country-to-country, but basically, investigators that have patients still receiving bavituximab need to file an IND or expanded access...”
3-13-17/CC/S.King(Q&A):
“We’re obviously seeing a number of patients that are still on therapy who are then coming in for quite now very long extended period of time, we feel like they’re getting benefit… for us that’s one of the reasons we’re still very happy and actually excited about the collaborations at Sloan Kettering & UTSW, in particular, where there’s not just an interest in studying bavituximab in preclinical models, but actually taking some of that data and eventually turning that into clinical indications where the drug excels.”

ABSTRACT:
Phosphatidylserine (PS) is a phospholipid that is exposed on surface of apoptotic cells, tumor cells and tumor endothelium. PS has been shown to promote immunosuppressive signals in the tumor microenvironment. Antibodies that target PS have been shown to reactivate anti-tumor immunity by polarizing tumor associated macrophages into a pro-inflammatory M1 phenotype, reducing the number of MDSCs in tumors and promoting the maturation of dendritic cells into functional APCs. In a mouse B16 melanoma model, targeting PS in combination with immune checkpoint blockade promoted greater anti-tumor activity than either agent alone. This combination was shown to enhance CD4+ and CD8+ T cell infiltration and activation in the tumors of treated animals. Radiation therapy (RT) is an effective focal treatment of primary solid tumors, but is less effective in treating metastatic solid tumors as a monotherapy. There is evidence that RT induces immunogenic tumor cell death and enhances tumor-specific T cell infiltration in treated tumors. The abscopal effect, a phenomenon in which tumor regression occurs outside the site of RT, has been observed in both preclinical and clinical trials when RT is combined with immunotherapy. In this study, we show that irradiation treatment of B16 melanoma causes an increase in PS expression on the surface of viable tumor and immune infiltrates. We subsequently examined the effects of combining RT with an antibody that targets PS (mch1N11) [“Mouse version of Bavituximab”] and immune checkpoint blockade (anti-PD-1) in B16 melanoma. We found that treatment with mch1N11 synergizes with RT to improve anti-tumor activity and overall survival in tumor bearing mice. In addition, the triple combination of mch1N11, RT and anti-PD-1 treatment displayed even greater anti-tumor and survival benefit. Analysis of local immune responses in the tumors of treated animals revealed an increase in tumor-associated macrophages with a shift towards a pro-inflammatory M1 phenotype after treatment with RT & mch1N11. In addition, analysis of the systemic immune responses in the spleen and tumor draining lymph nodes revealed an increase in CD8 T cell activation, effector cytokine production and differentiation into effector memory cells in the triple combination. This finding highlights the potential of combining these 3 agents to improve outcome in patients with advanced-stage melanoma and other cancers and may inform the design of clinical studies combining PS-targeting antibodies with RT and/or checkpoint blockade.

ABSTRACT:
A viable strategy to treat advanced cancers includes transferring of tumor-specific T cells. T cells that recognize tumor antigens can be expanded and reinvigorated ex-vivo. Furthermore, autologous T cells can be genetically modified to express anti-tumor T cell receptors or chimeric antigen receptors. Although the potency and specificity of tumor-specific T cells can be manipulated ex-vivo, once re-infused into patients, the T cells are subjected to immunosuppressive mechanisms established by the tumor. An important immune checkpoint regulator within tumors is phosphatidylserine (PS). Innate immune cells exposed to PS secrete suppressive cytokines and chemokines that can significantly impair the function and activation of anti-tumor T cells. Therefore, monoclonal antibodies that block PS activity can increase the anti-tumor potency of transferred T cells to treat aggressive cancers. Here we show that a PS targeting monoclonal antibody in combination with CD4+ T cells that recognize the melanoma antigen Trp1 can regress very advanced melanomas in all treated mice. Combination of anti-Trp1 CD4+ T cells with other immunomodulatory modalities such as anti-OX40 antibodies, can achieve equivalent treatment rates but these are typically accompanied by severe immune related adverse events. In contrast, in this setting, PS blockadedid not show any off-target toxicities. Flow cytometry analysis revealed lower levels of CD206 expression concomitant with higher activation markers in macrophages and neutrophils in tumors from anti-PS treated mice. These results suggest that diminishing suppressive mechanisms locally in adoptive transfer protocols is a highly desirable strategy that can eliminate tumors while minimizing related adverse events.

The 1st is investigating blockades (by inhibitory molecules called “checkpoints”) of T lymphocytes’ inhibitory receptors, which block immune responses; and the use of antibodies to remove the checkpoints, once again allowing white blood cells called T lymphocytes to kill the cancer cells.
Second, the Immunotherapy Dream Team is pursuing multiple Adoptive Cell Transfer (ACT) approaches, which increase immunity.”

“Combinational Activity of LAG3 & PD-1 Targeted Therapies is Significantly Enhanced by the Addition of Phosphatidylserine Targeting Antibodies and Establishes an Anti-Tumor Memory Response in Murine Triple Negative Breast Cancer”
=> Michael J. Gray, Jian Gong, Jeff Hutchins, Bruce Freimark (Peregrine Pharmaceuticals)
ABSTRACT:
Previous studies utilizing NanoString immune profile analysis demonstrated that intratumoral levels of LAG3 (lymphocyte activation gene 3) mRNA increased in response to phosphatidylserine (PS) and PD-1 targeting antibodies in murine triple negative breast cancers (TNBC). This suggests LAG3 acts to attenuate immune system activation during I/O therapies - and that PD-1 and LAG3 function cooperatively in suppressing immune system activation. Here we show that adding PS targeting antibodies can further enhance the effectiveness of antibodies targeting LAG3 and/or LAG3+PD-1. We first examined expression of LAG3 and PD-1 in the murine TNBC model E0771 and found that tumor associated T-cells (CD4+ and CD8+) have expression of both markers. Mice implanted with TNBC tumors were next treated with antibodies targeting PS, PD-1, and LAG3 alone and in combination with each other. Interestingly, the addition of PS targeting antibodies not only increased the effectiveness anti-PD-1 effectiveness as previously observed, but also enhanced anti-LAG3 treatment, showing that PS targeting antibodies are capable of augmenting additional I/O therapeutic regimens. Comparison of anti-PD-1+LAG3 combination vs. single anti-PD-1 or anti-LAG3 treatments showed moderately more anti-tumor activity than single treatments, however the addition of PS targeting antibodies to either checkpoint inhibitor was as equally effective in inhibiting tumor growth as observed in the anti-LAG3+PD-1 treatment. Further comparison of antibody treatments targeting PD-1+LAG3 vs. PS+PD-1+LAG3 demonstrated that the addition of PS targeting antibodies resulted in a significant decrease in tumor growth with complete tumor regression in 80% of the animals (along with the ability to completely reject secondary TNBC challenge) compared to 0% in the anti-PD-1+LAG3 treatment group. Immunoprofiling showed that the addition of PS targeting antibodies to these checkpoint therapies, including the combination of anti-PD-1+LAG3, resulted in a phenotype associated with enhanced immune system activation and immune-surveillance including increased tumor infiltrating lymphocytes (TILs) with upregulation of T-cell associated activation pathways, increased Th1 to Th2 profile, and enhanced antigen presentation processing /presentation mechanisms along with cytokines associated with immune system activation. Overall our data demonstrate that adding PS targeting antibodies to clinically relevant therapies, including PD-1 and LAG3, may significantly enhance their ability to activate and redirect the host immune system into recognition and elimination of tumor cells compared to single and combinational treatments that lack PS targeting antibodies.

[Note: clearly, this study is combining PPHM’s Anti-PS with ImmunoVaccine’s DepoVax Vaccine Adjuvanting Platform https://www.imvaccine.com/depovax.php ]
ABSTRACT:
Antibodies targeting phosphatidylserine (PS) have been shown to induce anti-tumor responses by induction of tumor-specific T cells. Based on this observation, we evaluated the responses of PS and PD-1 targeting antibody therapy to enhance anti-tumor responses of a HPV16 peptide vaccine formulated in DepoVax (DPX) in mice bearing HPV-transformed C3 mouse tumors. The addition of PS-targeting antibody (mch1N11) [“Mouse version of Bavituximab”] to DPX/metronomic cyclophosphamide (mCPA) immunotherapy prolonged survival in comparison to mice receiving an isotype control in combination with DPX/mCPA. When anti-PD-1 was added to mch1N11 + mCPA, there was no increase in survival. The addition of mch1N11 to DPX/mCPA immunotherapy had no effect on tumor growth or survival in the aggressive B16-F10 model. TIL analysis revealed an increase in CD8+ T cells, antigen specific CD8+ T cells and PD-1+ T cells in the tumor with mch1N11 treatment. The expression of surface markers for macrophages (CD68high, F4/80) and dendritic cells (CD11c) were also increased in the tumors of mice treated with mch1N11. RT-qPCR analysis of the tumor confirmed higher mRNA expression of T cells markers (CD8, Granzyme B, PD-1) and antigen presenting cell markers (F4/80, CD74). In the spleen, expression of cell surface markers for monocytes (CD11b) and PD-1+ T cells (CD8) were elevated in groups treated with mch1N11 in combination with anti-PD-1. Combined, these findings indicate that in this model, PS-targeting antibodies can enhance the activity of phagocytic cells involved in antigen presentation. We have found that PD-1 expression increases as anti-tumor activity increases, therefore these results also provide an indication that antibodies targeting PS enhance the anti-tumor immune response induced by DPX/mCPA therapy. The observations suggest that PS-targeting antibodies may enhance therapeutic vaccines for the treatment of cancer.

DR. JEDD WOLCHOK: "Based on these study results, we believe that the targeting of PS is having meaningful activity within the tumor microenvironment in the B16 melanoma model. It appears that this activity creates a more immune active environment in which other treatments, including radiation, are able to have a greater anti-tumor impact."
DR. TAHA MERGHOUB (Co-Dir., Ludwig Collaborative Lab at MSK): "We have noted that the combination of PS-targeting treatment and radiation, as well as triple combination of PS-targeting treatment, radiation and anti-PD-1, resulted in clear advantages in anti-tumor activity in the mouse B16 melanoma model. We believe that these findings suggest the potential benefit of combining these agents to improve the outcomes of patients with cancer. With this in mind, we think this research may play an important role in designing future clinical trials of PS-targeting agents in melanoma and other cancers."

ABSTRACT:
Phosphatidylserine (PS) is a phospholipid that is exposed on surface of apoptotic cells, tumor cells and tumor endothelium. PS has been shown to promote immunosuppressive signals in the tumor microenvironment. Antibodies that target PS have been shown to reactivate anti-tumor immunity by polarizing tumor associated macrophages into a pro-inflammatory M1 phenotype, reducing the number of MDSCs in tumors and promoting the maturation of dendritic cells into functional APCs. In a mouse B16 melanoma model, targeting PS in combination with immune checkpoint blockade promoted greater anti-tumor activity than either agent alone. This combination was shown to enhance CD4+ and CD8+ T cell infiltration and activation in the tumors of treated animals. Radiation therapy (RT) is an effective focal treatment of primary solid tumors, but is less effective in treating metastatic solid tumors as a monotherapy. There is evidence that RT induces immunogenic tumor cell death and enhances tumor-specific T cell infiltration in treated tumors. The abscopal effect, a phenomenon in which tumor regression occurs outside the site of RT, has been observed in both preclinical and clinical trials when RT is combined with immunotherapy. In this study, we show that irradiation treatment of B16 melanoma causes an increase in PS expression on the surface of viable tumor and immune infiltrates. We subsequently examined the effects of combining RT with an antibody that targets PS (mch1N11) [“Mouse version of Bavituximab”] and immune checkpoint blockade (anti-PD-1) in B16 melanoma. We found that treatment with mch1N11 synergizes with RT to improve anti-tumor activity and overall survival in tumor bearing mice. In addition, the triple combination of mch1N11, RT and anti-PD-1 treatment displayed even greater anti-tumor and survival benefit. Analysis of local immune responses in the tumors of treated animals revealed an increase in tumor-associated macrophages with a shift towards a pro-inflammatory M1 phenotype after treatment with RT & mch1N11. In addition, analysis of the systemic immune responses in the spleen and tumor draining lymph nodes revealed an increase in CD8 T cell activation, effector cytokine production and differentiation into effector memory cells in the triple combination. This finding highlights the potential of combining these 3 agents to improve outcome in patients with advanced-stage melanoma and other cancers and may inform the design of clinical studies combining PS-targeting antibodies with RT and/or checkpoint blockade.

ABSTRACT:
A viable strategy to treat advanced cancers includes transferring of tumor-specific T cells. T cells that recognize tumor antigens can be expanded and reinvigorated ex-vivo. Furthermore, autologous T cells can be genetically modified to express anti-tumor T cell receptors [TCRs] or chimeric antigen receptors [CARs]. Although the potency and specificity of tumor-specific T cells can be manipulated ex-vivo, once re-infused into patients, the T cells are subjected to immunosuppressive mechanisms established by the tumor. An important immune checkpoint regulator within tumors is phosphatidylserine (PS). Innate immune cells exposed to PS secrete suppressive cytokines and chemokines that can significantly impair the function and activation of anti-tumor T cells. Therefore, monoclonal antibodies that block PS activity can increase the anti-tumor potency of transferred T cells to treat aggressive cancers. Here we show that a PS targeting monoclonal antibody in combination with CD4+ T cells that recognize the melanoma antigen Trp1 can regress very advanced melanomas in all treated mice. Combination of anti-Trp1 CD4+ T cells with other immunomodulatory modalities such as anti-OX40 antibodies, can achieve equivalent treatment rates but these are typically accompanied by severe immune related adverse events. In contrast, in this setting, PS blockade did not show any off-target toxicities. Flow cytometry analysis revealed lower levels of CD206 expression concomitant with higher activation markers in macrophages and neutrophils in tumors from anti-PS treated mice. These results suggest that diminishing suppressive mechanisms locally in adoptive transfer protocols is a highly desirable strategy that can eliminate tumors while minimizing related adverse events.

8-2015: Presently there are 3 types of Adoptive Cell Transfer (ACT) using effector T cells that are advancing on a path towards regulatory approval:
1. TILs (tumor infiltrating lymphocytes) have been developed with slow but continuing progress over several decades.
2. CARs (chimeric antibody receptors) – newer gene-modified T cells strategy
3. TCRs (T-cell receptors) – newer gene-modified T cells strategy

Beg@:39:
“Immunotherapy drugs release this brake and empower immune cells to fight the cancer.
Sometimes the immune system needs a tune-up before it can fight cancer.
Immune cells can be removed from the body, armed with new proteins that can target cancer cells, and given back to a patient in large numbers.
Once inside the body, the modified immune cells recognize and attack the cancer.
This approach is called CAR T cell therapy. [an Adoptive Cell Transfer “ACT” strategy]
Despite the promise of immunotherapy, not everybody responds.
MSKCC scientists are exploring ways to improve immunotherapy.”

“Combinational Activity of LAG3 & PD-1 Targeted Therapies is Significantly Enhanced by the Addition of Phosphatidylserine Targeting Antibodies and Establishes an Anti-Tumor Memory Response in Murine Triple Negative Breast Cancer”
=> Michael J. Gray, Jian Gong, Jeff Hutchins, Bruce Freimark (Peregrine Pharmaceuticals)
ABSTRACT:
Previous studies utilizing NanoString immune profile analysis demonstrated that intratumoral levels of LAG3 (lymphocyte activation gene 3) mRNA increased in response to phosphatidylserine (PS) and PD-1 targeting antibodies in murine triple negative breast cancers (TNBC). This suggests LAG3 acts to attenuate immune system activation during I/O therapies - and that PD-1 and LAG3 function cooperatively in suppressing immune system activation. Here we show that adding PS targeting antibodies can further enhance the effectiveness of antibodies targeting LAG3 and/or LAG3+PD-1. We first examined expression of LAG3 and PD-1 in the murine TNBC model E0771 and found that tumor associated T-cells (CD4+ and CD8+) have expression of both markers. Mice implanted with TNBC tumors were next treated with antibodies targeting PS, PD-1, and LAG3 alone and in combination with each other. Interestingly, the addition of PS targeting antibodies not only increased the effectiveness anti-PD-1 effectiveness as previously observed, but also enhanced anti-LAG3 treatment, showing that PS targeting antibodies are capable of augmenting additional I/O therapeutic regimens. Comparison of anti-PD-1+LAG3 combination vs. single anti-PD-1 or anti-LAG3 treatments showed moderately more anti-tumor activity than single treatments, however the addition of PS targeting antibodies to either checkpoint inhibitor was as equally effective in inhibiting tumor growth as observed in the anti-LAG3+PD-1 treatment. Further comparison of antibody treatments targeting PD-1+LAG3 vs. PS+PD-1+LAG3 demonstrated that the addition of PS targeting antibodies resulted in a significant decrease in tumor growth with complete tumor regression in 80% of the animals (along with the ability to completely reject secondary TNBC challenge) compared to 0% in the anti-PD-1+LAG3 treatment group. Immunoprofiling showed that the addition of PS targeting antibodies to these checkpoint therapies, including the combination of anti-PD-1+LAG3, resulted in a phenotype associated with enhanced immune system activation and immune-surveillance including increased tumor infiltrating lymphocytes (TILs) with upregulation of T-cell associated activation pathways, increased Th1 to Th2 profile, and enhanced antigen presentation processing /presentation mechanisms along with cytokines associated with immune system activation. Overall our data demonstrate that adding PS targeting antibodies to clinically relevant therapies, including PD-1 and LAG3, may significantly enhance their ability to activate and redirect the host immune system into recognition and elimination of tumor cells compared to single and combinational treatments that lack PS targeting antibodies.

[Note: clearly, this study is combining PPHM’s Anti-PS with ImmunoVaccine’s DepoVax Vaccine Adjuvanting Platform https://www.imvaccine.com/depovax.php ]
ABSTRACT:
Antibodies targeting phosphatidylserine (PS) have been shown to induce anti-tumor responses by induction of tumor-specific T cells. Based on this observation, we evaluated the responses of PS and PD-1 targeting antibody therapy to enhance anti-tumor responses of a HPV16 peptide vaccine formulated in DepoVax (DPX) in mice bearing HPV-transformed C3 mouse tumors. The addition of PS-targeting antibody (mch1N11) [“Mouse version of Bavituximab”] to DPX/metronomic cyclophosphamide (mCPA) immunotherapy prolonged survival in comparison to mice receiving an isotype control in combination with DPX/mCPA. When anti-PD-1 was added to mch1N11 + mCPA, there was no increase in survival. The addition of mch1N11 to DPX/mCPA immunotherapy had no effect on tumor growth or survival in the aggressive B16-F10 model. TIL analysis revealed an increase in CD8+ T cells, antigen specific CD8+ T cells and PD-1+ T cells in the tumor with mch1N11 treatment. The expression of surface markers for macrophages (CD68high, F4/80) and dendritic cells (CD11c) were also increased in the tumors of mice treated with mch1N11. RT-qPCR analysis of the tumor confirmed higher mRNA expression of T cells markers (CD8, Granzyme B, PD-1) and antigen presenting cell markers (F4/80, CD74). In the spleen, expression of cell surface markers for monocytes (CD11b) and PD-1+ T cells (CD8) were elevated in groups treated with mch1N11 in combination with anti-PD-1. Combined, these findings indicate that in this model, PS-targeting antibodies can enhance the activity of phagocytic cells involved in antigen presentation. We have found that PD-1 expression increases as anti-tumor activity increases, therefore these results also provide an indication that antibodies targeting PS enhance the anti-tumor immune response induced by DPX/mCPA therapy. The observations suggest that PS-targeting antibodies may enhance therapeutic vaccines for the treatment of cancer.

TAHA MERGHOUB (Co-Dir., Ludwig Collaborative Lab at MSK): "We have noted that the combination of PS-targeting treatment and radiation, as well as triple combination of PS-targeting treatment, radiation and anti-PD-1, resulted in clear advantages in anti-tumor activity in the mouse B16 melanoma model. We believe that these findings suggest the potential benefit of combining these agents to improve the outcomes of patients with cancer. With this in mind, we think this research may play an important role in designing future clinical trials of PS-targeting agents in melanoma and other cancers."

...Dr. Wolchock states, ”The phosphatidylserine (PS) signaling pathway is a very interesting target for modulating the immune system's response to cancer. We look forward to exploring the potential of PS-targeting agents alone and with other immune modulators that may lead to novel advances in cancer therapy.”
...Dr. Taha Merghoub states, "A key focus of the Wolchok Lab's research is studying novel immunotherapy combinations that work together to enable the immune system to recognize & destroy cancer. This collaboration will allow us to focus on the role & contribution of PS blockade therapy in determining which combination of the current & next gen. of immune modulators is likely to increase the extent & amplitude of anti-tumor response. This important pre-clinical and translational work will potentially guide the design of the next gen. of clinical studies with bavituximab.”

3-13-17/CC: “There are patients still still receiving bavituximab.”

3-13-17/CC: JOE SHAN (VP/Clin.&Reg. Affairs) – CLINICAL TRIALS:
“During the quarter, we continued to wrap-up patient treatment and follow-up with our SUNRISE trial. While the study was discontinued in Feb.2016, follow-up data collection continues, and patients assigned to bavituximab containing arm were allowed to continue receiving study drugs, if the investigators determined it was in the patients’ best interest. This has been a valuable effort and we are very pleased with the amount of data that has been collected over the past year. It is important to mention that we are now working diligently to transition the remaining patients still receiving bavituximab to compassionate-use programs...”

3-13-17 Q&A: [beg. 20:30]
1. Kumara Raja - Noble Life Science Partners http://noblelsp.com/research
KR: ”...In terms of the SUNRISE trials, what are you seeing in patients who are continuing on bavituximab? What kind of benefits are you seeing there? And you’ve talked about Compassionate Use Program, what needs to be done for that in different countries?”
STEVE KING: …For the question regarding patients that are still on bavi and how are they doing, and the Compassionate Use, I’ll turn it over to Joe.
JOE SHAN: ...There are of course patients still as we mentioned still receiving bavituximab, so that gives you an indication that there are patients that are not only, what we call long-term survivors but there are diseases that stabilized. That’s why it's was important that the trial is formally concluded that we allow the patients the opportunity to continue receiving bavituximab under compassionate use...Regarding the compassionate use, the procedure varies from country-to-country, but basically, investigators that have patients still receiving bavituximab need to file an IND or expanded access to application in the U.S. It’s a single patient IND, and in Europe it's under the expanded access. It’s a bit of paper work, but we’re assisting where we can, but basically the investigator takes responsibility from that point on, and the approvals are pretty quick.
STEVE KING: That’s one of the things that we see with bavituximab is, while we’re all disappointed that the overall trial results weren’t what we expected, certainly, you see these anecdotal signs where we obviously see a number of patients that are still on therapy who are then coming in for quite now very long extended period of time, we feel like they’re getting benefit. You see these anecdotal signs activity in those patients that have been on therapy, and for us that’s one of the reasons we’re still very happy and actually excited about the collaborations at Sloan Kettering and UTSW, in particular, where there’s not just an interest in studying bavituximab in preclinical models, but actually taking some of that data and eventually turning that into clinical indications where the drug excels.

ABSTRACT - BACKGROUND:
SUNRISE, a global, double-bind, Phase III trial of docetaxel (D) + bavituximab (B) or D plus placebo (P) in previously treated non-squamous NSCLC, demonstrated similar overall survival (OS) in both treatment arms. Biomarkers including pre-treatment PD-L1 expression are being retrospectively assessed in on-going exploratory analyses.
METHODS:
Archival tissue obtained at the time of diagnosis was requested but not required in the SUNRISE trial. FFPE slides were stained with a panel of lymphoid cell markers: CD3+, CD8+, FoxP3+, PD-L1+, CD163+, CK+ and DAPI using a 6-plex quantitative immunohistochemistry (IHC) assay (OPAL, PerkinElmer, Hopkinton, MA). Baseline PD-L1 expression was retrospectively scored on tumor cells (TC) as a percentage of PD-L1 expressing tumor cells: TC3>=50%, TC2>=5% and < 50%, TC1>=1% and < 5%, and TC0 < 1%. Cox regression models for PD-L1 IHC subgroup populations were used for correlation with OS.
RESULTS:
In the subset of patients with available diagnostic biopsies (110 out of 597 randomized patients), the prevalence of PD-L1 expression was 5% for TC3, 18% for TC2/3, 35% for TC1/2/3, 65% for TC0. Median OS (mOS) of the D+B arm is 11.5 months (TC0, < 1%) and 6.0 months (TC1/2/3, >=1%) with HR 0.38 (95% CI, 0.19-0.76); p-value = 0.004. mOS of the D+P arm is 11.1 months (TC0, < 1%) and 10.4 months (TC1/2/3, >=1%) with HR 0.93 (95% CI, 0.47-1.87); p value = 0.844.
CONCLUSIONS:
Baseline PD-L1 expression in a subset of SUNRISE patients demonstrated that PD-L1 expression (TC0) was associated with a significantly prolonged OS compared to positive PD-L1 expression (TC1/2/3) in patients receiving D+B. No difference in OS was observed in the D+P group by PD-L1 expression. These observations are consistent with the hypothesis that bavituximab may demonstrate more effect in PD-L1 negative or low expressing “immune cold” tumors.

ABSTRACT
BACKGROUND:
Bavituximab is a chimeric monoclonal antibody that targets the membrane phospholipid phosphatidylserine (PS) exposed on endothelial cells and cancer cells in solid tumors. Our previous studies showed that bavituximab enhances the activation of CD8+ TILs that correlates with increased cytokine production by lymphoid and myeloid cells in lung cancer with low PD-L1 expression suggesting that the interruption of the PD-1/PD-L1 axis by nivolumab may enhance the bavituximab effect in tumors.
METHODS:
Fresh tumor tissues obtained from consented patients with NSCLC at the time of surgical resection were utilized in a 3D ex vivo tumor miscrosphere assay, where 3D tumor microspheres were treated with bavituximab or nivolumab alone or in combination at 10 mg/ml for 36 hours. At the end of the treatment, a multiplex human cytokine assay was used to simultaneously analyze the differential secretion of cytokines, including human IFNg, in culture media as a surrogate of TIL activation. In addition, a gene expression analysis using a NanoString platform containing probes to quantitate 770 immune function genes.
RESULTS:
Preliminary results indicate the combination treatment with bavituximab & nivolumab led to increased expression of genes involved in M1 polarization of tumor associated macrophages in a subpopulation of lung tumors that closely correlated with release of cytokines such as MIP1b (CCL4) which is a chemoattractant for natural killer cells, monocytes and a variety of other cells involved in tumor immune response.
CONCLUSIONS:
This lung patient derived ex-vivo approach indicates that bavituximab in combination with nivolumab may enhance immune response. This response likely involves M1 polarization of tumor associated macrophages and suggests potential clinical implications in the treatment of lung cancer.

#298016 RE: cjgaddy #290976

Nasdaq appeal decision could come as-late-as 7-2-17
I did not know this: “The Hearing Panel typically issues a decision within 30 days of the hearing.” If anybody sees any errors I’ve made, let me know and I’ll fix & re-post.

A. DETERMINATION LETTER (company does not meet the stds. for continued listing).
...Peregrine recv’d this 4-11-17, per subsequent Form 8-K: https://www.sec.gov/Archives/edgar/data/704562/000168316817000902/peregrine_8k.htm

B. NASDAQ APPEAL REQUEST: The company then has 7 days to appeal the determination. The company is typically scheduled for a hearing 30-45 days from the date of its request for a hearing, and informed of this date & time within a week of its request.
* The Latest date possible for the Hearing would be 4-18-17 + 45days = 6-2-17 (Friday).

C. HEARING: A company is allotted approx. 50 mins. to make its presentation. The hearing takes place in a conference room before 2 panelists (2 professionals from the business community, who are indep. of Nasdaq – the pool of panelists includes academics, accountants, auditors, corporate officers, investor advocacy representatives, investment bankers, securities lawyers, and venture capitalists), a Hearings Advisor, and a court reporter. Nasdaq does not typically attend, but may; if Nasdaq decides to attend, the company will be informed. A company may make its presentation in any form it wishes and should expect questions from the Panel. The Panel will want to understand the reasons for the company's deficiency and the specific details of its plan of compliance, including a timeline for regaining compliance... Nasdaq does not make a Panel's decision letter publicly available. However, Nasdaq cannot guarantee confidentiality since documents & information provided to Nasdaq may be subject to subpoenas from private parties or requests for access from federal or state gov’t agencies & self-regulatory bodies.

D. DECISION. The Hearing Panel typically issues a decision within 30 days of the hearing.
* For Peregrine, decision could be as late as (6-2-17 + 30days) = 7-2-17 (Sunday).

E. FURTHER APPEALS. May a company appeal a Hearing Panel's decision? Yes. A company may appeal a Panel's decision to the Listing Council. The Listing Council may also decide to call the decision for review. The appeal to the Listing Council does not stay a Panel's decision or the suspension of the trading of a company's shares pending a final determination by the Listing Council. If the Listing Council overturns a Panel decision, then the company's securities may be reinstated on Nasdaq. After a determination by the Listing Council, a company may appeal to the SEC and, from there, it may proceed to the federal court system.

Peregrine’s 4-11-17 Form 8-K, “Notice of Delisting: Received:
“On April 11, 2017, Peregrine received a letter from NASDAQ stating that the Company has not regained compliance with the $1.00 min. closing bid price requirement… The letter further states that the Nasdaq has determined to delist the Company’s securities on April 20, 2017, unless the Company requests a hearing before the NASDAQ Hearings Panel by April 18, 2017 to appeal the Staff’s determination to delist its securities. The Company intends to timely request such a hearing before the Panel, and such request will stay any delisting action by the Staff pending the issuance of a written Panel decision. The Panel will typically hold a hearing to consider an appeal within 45 days after the request for a hearing is made. At the hearing, the Company will present its plan to regain compliance with the requirements for continued listing on The NASDAQ Capital Market. The Company is considering several paths to regain compliance with the Minimum Bid Price Requirement, including, among other things, a reverse stock split. As previously disclosed, the Company’s stockholders approved a reverse stock split of the Company’s common stock at a ratio of up to 1-for-7, to be determined by the Company’s Board of Directors in its sole discretion and effected, if at all, at any time until the Company’s 2017 annual meeting of stockholders [~10-12-18].”

3-13-17 Qtly. Conf. Call (King/Shan/Worsley/Lytle) Transcript http://tinyurl.com/grhwjvy
PL: “Switching gears now, I’d like to address our plans to preserve our NASDAQ listing. At a backdrop, last April, we were notified by the NASDAQ that our share price did not meet the $1 min. bid price for 30 consecutive days, which is a requirement for continued listing on the NASDAQ market. At that time, we were automatically afforded an initial compliance period of 180 days or until Oct. 10, 2016 to regain compliance. At the end of the initial compliance period, we requested and were granted a 180 day extension to regain compliance. This 2nd extension period will end on April 10, 2017. Let me discuss our strategy and future steps we plan to take over the next few months. First & foremost, we have determined that it is not in the best interest of our stockholders to affect a reverse stock split prior to April 10, 2017. If our share price does not trade above $1 for 10 consecutive trading days by April 10th, we expect to receive a notice of delisting. If we received this notice, we will appeal this decision within the required 7 days and this appeal will stay any delisting actions by NASDAQ. At that point, NASDAQ will schedule a hearing, which is typically held within 45 days, and we will present our plan to regain compliance. We are considering several paths to regain compliance, including having addl. time to continue to allow the market to adjust, to reflect the current value of Avid as evidence with the recent movement in our share price. The hearing panel could afford us up to 180 addl. days to regain compliance, although this addl. time is not guaranteed and this decision is at the discretion of the NASDAQ’s hearing panel. If we are not afforded addl. time from this panel, it is important to note that our stockholders approved the Board’s ability to implement a reverse stock split at a ratio of up to 1:7 as a means to regain compliance and to preserve our listing on NASDAQ. During this entire process, Peregrine will continue to be listed on that NASDAQ capital market as it does today. We will keep you informed on any material developments through our SEC filings on Form 8-K as we execute on this plan.”

ASCO'17: “Prelim-Correlative-Analysis of PD-L1 Expr. from SUNRISE (Biomarker#4)” - press release, poster image, abstract detail...

6-5-17/PR: Peregrine Pharmaceuticals Presents Preliminary Correlative Analysis of PD-L1 Expression from SUNRISE Trial at ASCO 2017
-- Negative PD-L1 Expression was Associated with a Significantly Longer Median Overall Survival Compared to Positive PD-L1 Expression in Patients Receiving Docetaxel Plus Bavituximab
-- Presented Results Support Hypothesis that Bavituximab May Demonstrate Greater Effect in "Cold" Tumors Expressing Low to No PD-L1
http://ir.peregrineinc.com/releasedetail.cfm?ReleaseID=1028997
TUSTIN, June 05, 2017: Peregrine Pharmaceuticals, Inc. (NASDAQ:PPHM/PPHMP), a biopharmaceutical company committed to improving patient lives by advancing its proprietary R&D pipeline and manufacturing high quality products for biotechnology and pharmaceutical companies, today announced the presentation of promising new data from its Phase III SUNRISE trial of bavituximab in patients with previously treated locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC). Presented results demonstrated that patients in the study's bavituximab treatment arm who had low baseline PD-L1 expression levels had a statistically significant improvement in median overall survival (mOS) as compared to patients in the same treatment arm who had higher baseline levels of PD-L1. Data were presented by Peregrine scientists at the Annual Meeting of the American Society of Clinical Oncology (ASCO), being held June 2-6, 2017 in Chicago.

Data presented demonstrated that patients in the study's docetaxel plus bavituximab (D+B) treatment arm with a pre-treatment PD-L1 expression level on tumor cells of < 1% (TC0) had a mOS of 12.1 months compared to a mOS of 6.1 months for patients with PD-L1 expression >=1% (TC1/2/3) (HR = 0.42 p=0.007). There was no difference in mOS based on PD-L1 expression levels observed in the study's docetaxel plus placebo (D+P) control arm (10.7 months for TC0 vs. 11.1 months for TC1/2/3; HR = 0.87; p=0.609).

"We believe that these latest observations from the SUNRISE trial further support the hypothesis that bavituximab, through its immune modulating mechanism, may have more effect on tumors without pre-existent immunity. These ‘cold' tumors suppress normal anti-tumor immune response and are categorized by very low to no PD-L1 expression on tumor cells," said Joseph Shan, VP of Clinical & Regulatory Affairs at Peregrine. "These latest findings, along with other recently announced clinical and preclinical data from our PS-targeting program, inform our clinical development strategy going forward and provide additional rationale for combining bavituximab with checkpoint inhibitors."

As part of the SUNRISE clinical study protocol, researchers requested but did not require that patients provide a tumor tissue sample at the time of diagnosis. In total, tissue samples were collected from 129 of the trial's 597 patients and were assessed retrospectively for baseline PD-L1 expression levels on tumor cells. Of the 129 tissue samples collected, 122 were evaluable for PD-L1 expression on tumor cells (54 in D+B arm and 68 in D+P control arm). Of the evaluable samples in the D+B arm, 69% demonstrated PD-L1 expression levels < 1%, as compared to 59% in the D+P arm.

Bavituximab is an investigational immune-modulatory monoclonal antibody that targets phosphatidylserine (PS). PS inhibits the ability of immune cells to recognize and fight tumors. Bavituximab is believed to reverse PS-mediated immunosuppression by blocking the engagement of PS with its receptors as well as by sending an alternate immune activating signal. PS-targeting antibodies have been shown to shift the functions of immune cells in tumors, resulting in multiple signs of immune activation and anti-tumor immune responses.

Peregrine's clinical development strategy for bavituximab currently focuses on small, early-stage, proof-of-concept trials evaluating the drug in combination with other cancer treatments. This approach includes grants awarded by the National Comprehensive Cancer Network (NCCN) to support 3 different clinical trials of bavituximab treatment combinations. These trials will evaluate novel bavituximab combinations in glioblastoma, head and neck cancer, and hepatocellular carcinoma including an immunotherapy combination. Additionally, Peregrine continues to advance its pre-clinical collaboration with Memorial Sloan Kettering Cancer Center (MSK) with the goal of evaluating combinations of PS targeting antibodies with checkpoint inhibitors and other immune stimulatory agents. Peregrine's intent behind this strategy is to focus its research and development spending to further validate bavituximab's combination potential as the company seeks to advance the program though a pharmaceutical or biotechnology partner.

ORIG. ABSTRACT (superceded by 6-5-17 PPHM PR)...
BACKGROUND:
SUNRISE, a global, double-bind, Phase III trial of docetaxel (D) + bavituximab (B) or D plus placebo (P) in previously treated non-squamous NSCLC, demonstrated similar overall survival (OS) in both treatment arms. Biomarkers including pre-treatment PD-L1 expression are being retrospectively assessed in on-going exploratory analyses.
METHODS:
Archival tissue obtained at the time of diagnosis was requested but not required in the SUNRISE trial. FFPE slides were stained with a panel of lymphoid cell markers: CD3+, CD8+, FoxP3+, PD-L1+, CD163+, CK+ and DAPI using a 6-plex quantitative immunohistochemistry (IHC) assay (OPAL, PerkinElmer, Hopkinton, MA). Baseline PD-L1 expression was retrospectively scored on tumor cells (TC) as a percentage of PD-L1 expressing tumor cells: TC3>=50%, TC2>=5% and < 50%, TC1>=1% and < 5%, and TC0 < 1%. Cox regression models for PD-L1 IHC subgroup populations were used for correlation with OS.
RESULTS:
In the subset of patients with available diagnostic biopsies (110 out of 597 randomized patients), the prevalence of PD-L1 expression was 5% for TC3, 18% for TC2/3, 35% for TC1/2/3, 65% for TC0. Median OS (mOS) of the D+B arm is 11.5 months (TC0, < 1%) and 6.0 months (TC1/2/3, >=1%) with HR 0.38 (95% CI, 0.19-0.76); p-value = 0.004. mOS of the D+P arm is 11.1 months (TC0, < 1%) and 10.4 months (TC1/2/3, >=1%) with HR 0.93 (95% CI, 0.47-1.87); p value = 0.844.
CONCLUSIONS:
Baseline PD-L1 expression in a subset of SUNRISE patients demonstrated that PD-L1 expression (TC0) was associated with a significantly prolonged OS compared to positive PD-L1 expression (TC1/2/3) in patients receiving D+B. No difference in OS was observed in the D+P group by PD-L1 expression. These observations are consistent with the hypothesis that bavituximab may demonstrate more effect in PD-L1 negative or low expressing “immune cold” tumors.

ABSTRACT
BACKGROUND:
Bavituximab is a chimeric monoclonal antibody that targets the membrane phospholipid phosphatidylserine (PS) exposed on endothelial cells and cancer cells in solid tumors. Our previous studies showed that bavituximab enhances the activation of CD8+ TILs that correlates with increased cytokine production by lymphoid and myeloid cells in lung cancer with low PD-L1 expression suggesting that the interruption of the PD-1/PD-L1 axis by nivolumab [BMS’ Opdivo] may enhance the bavituximab effect in tumors.
METHODS:
Fresh tumor tissues obtained from consented patients with NSCLC at the time of surgical resection were utilized in a 3D ex vivo tumor miscrosphere assay, where 3D tumor microspheres were treated with bavituximab or nivolumab alone or in combination at 10 mg/ml for 36 hours. At the end of the treatment, a multiplex human cytokine assay was used to simultaneously analyze the differential secretion of cytokines, including human IFNg, in culture media as a surrogate of TIL activation. In addition, a gene expression analysis using a NanoString platform containing probes to quantitate 770 immune function genes.
RESULTS:
Preliminary results indicate the combination treatment with bavituximab & nivolumab led to increased expression of genes involved in M1 polarization of tumor associated macrophages in a subpopulation of lung tumors that closely correlated with release of cytokines such as MIP1b (CCL4) which is a chemoattractant for natural killer cells, monocytes and a variety of other cells involved in tumor immune response.
CONCLUSIONS:
This lung patient derived ex-vivo approach indicates that bavituximab in combination with nivolumab may enhance immune response. This response likely involves M1 polarization of tumor associated macrophages and suggests potential clinical implications in the treatment of lung cancer.

WELCOME & FWD-LOOKING STATEMENTS: Tim Brons, Vida Strategic Partners (IR) http://www.peregrineinc.com

CEO STEVE KING – OPENING COMMENTS:
Thanks to all of you who have dialed in and all of you who are participating via webcast today. As most of you’re aware, Peregrine has a diverse business with a common goal of improving the lives of patients with serious diseases. We do this by manufacturing high-quality pharmaceutical products through our contract manufacturing business, Avid Bioservices, and by advancing cancer therapies & diagnostics, led by bavituximab, our novel immunotherapy product, through our R&D company, Peregrine. We continue to believe there are significant opportunities for both of these businesses, but also recognize they are very distinct businesses with very different roads to success.

I will first discuss recent highlights with the 2 companies and then more about potential plans to ensure the success of both companies. We’re very pleased to announce that Avid Bioservices recorded its highest annual revenues to-date during FY17, topping $57mm, representing 30% growth over the prior FY. Revenues could have been even higher if not for the need to delay shipment of several already released lots of materials due to the needs of the customer. While we’re pleased at the continued yr-over-yr revenue growth, we are projecting relatively flat revenues this FY due to recent changes in a large customer’s [Halozyme] forecasts and a delayed regulatory filing for another significant customer. We expect both of these factors to be temporary and remain confident that Avid will continue to achieve growth in the future, as these customers are successful and as we add new customers to diversify our client base. And on that front, we have recently signed 4 new customers that we expect to contribute significantly to top line revenues in the future.

In addition, we successfully completed 3 process validation campaigns for existing third-party customers, which again, we believe can have a significant revenue impact as the customers make regulatory filings and begin to move toward inventory builds for potential launch, followed of course by the potential for commercial supply. In addition to securing new customers and setting the stage for commercial production, we are continuing to make other important steps to ensure Avid’s growth in the coming years. As part of this effort, we have recently installed 2 new 2,000L bioreactors in our Myford facility, and we have already secured commitments for this capacity. Due to its state-of-the-art modular design, there is the potential to install addl. bioreactors in our Myford facility, which will allow us to continue to meet the increasing demand and grow the future business with our current facilities. Another part of our effort to attract new customers is to expand our service offerings. Our scientists have developed a state-of-the-art antibody discovery & characterization platform through which we can generate antibodies against virtually any target. These capabilities are meant to allow rapid screening for high affinity antibodies that are developable. These capabilities are a natural extension of the services we already offer through Avid and it represents an attractive way to bringing customers at a much earlier stage of development with the potential to move them quickly into process developments and cGMP manufacturing.

Switching gears to our R&D activities. While meeting our goal of reducing overall R&D spending by over 50% during FY17, we were also able to generate some of the most compelling data to-date supporting the combination of bavituximab & checkpoint inhibitors. We are working with some of the best institutions in the world that have been involved in the development of cancer immunotherapies. Perhaps the most important recent preclinical findings came through original research from our collaborators at Memorial Sloan Kettering Cancer Center (MSKCC). The researchers at MSKCC [Jedd Wolchok’s Lab] presented promising preclinical data [4-3-17/AACR17: http://tinyurl.com/lxlltd6 ] combining PS-targeting antibodies with adoptive T cell transfer therapy [ACT: CAR-T], which may support the combination of bavituximab with CAR-T cell immunotherapy in the future.

On the clinical front, we presented data from an analysis of the maturing SUNRISE Phase III trial [4-3-17/AACR17: #CT159/25, “IFN-y Analysis In Blood & Tissue as a Potential Prognostic and/or Predictive Biomarker” (Sunrise Biomarker #3) http://tinyurl.com/ktzr782 ], showing that patients in the arm that received bavituximab and subsequent immune checkpoint inhibitors lived significantly longer than those on the cohorts that received placebo and subsequently went on to immune checkpoint inhibitors. The data was impressive. It has been very well received by KOLs, and we believe strongly supports advancing bavituximab in combination with immune checkpoint inhibitors, such as PD-1 & PD-L1 inhibitors. Joe will talk more about this data shortly.

The data presented at AACR by the researchers at MSKCC and Peregrine collectively provide growing validation for the potential bavituximab in combination with immune stimulating therapies. Such as those we are exploring our collaboration with the National Comprehensive Cancer Network (NCCN), which will evaluate novel bavituximab combinations in Glioblastoma, Head & Neck cancer, and Hepatocellular Carcinoma, including a PD-1 combination. This collaboration is advancing well and again Joe will provide more details on the 3 trials during his prepared remarks.

The Antibody Discovery Platform discussed earlier [Avid] could also be instrumental on the R&D side of the business, allowing us to rapidly identify antibodies against already validated targets, as well as the potential to identify novel targets. As we think about diversifying our development pipeline to include lower risk, already validated targets, this new capability could help us to identify developable antibodies that could have short-term value, as the need for such antibodies is on the rise. And this approach fits very well into our core capabilities and experience in the development of monoclonal antibodies. You can expect to hear more about this new capability over the coming months on both sides of our business.

Lastly, on the R&D side, we are pleased to report that the company continues to make progress with its PS-targeting Exosome Diagnostic Technology that is designed to detect & monitor cancer. Our scientists have successfully optimized the assay and we are currently preparing to generate addl. Data, testing the diagnostic with an expanded set of human samples. Such data will be important to partnering discussions and we’ll keep you posted on progress.

Both Peregrine & Avid have achieved important milestones in recent quarters. We are proud of both businesses and believe each has strong potential. However, we also recognize that they have very different business models and pathways to growth. As a result, we understand that some of our shareholders have divergent goals for the company’s future, depending on if they’re more focused on Avid or our R&D business [7-13-17: Ronin/SW-Invest Letter to Stockholders; PPHM Comments http://tinyurl.com/ybr8ycbp ]. So, as part of our continuous evaluation of various strategic options that we believe they enhance value for all of our stockholders, we are seriously considering the possibility of separating our 2 distinct businesses. We’re still at the early stages of evaluating this strategic opportunity, but are diligently moving forward with the analysis. I’ll now turn the call over to the other members of our team, who will give a detailed overview of our clinical, corporate, and CDMO activities.

JOE SHAN (VP/Clin.&Reg. Affairs) – CLINICAL TRIALS:
As Steve mentioned just a few moments ago, despite a significant reduction in R&D spending over the past FY, we were able to continue patient treatment & follow-up in the Phase III SUNRISE trial thus allowing the clinical data to further mature.

At the AACR annual meeting in April, we presented the most important and compelling data to-date supporting bavituximab’s potential to improve the outcome of anti-PD-1 or PD-L1 immune checkpoint inhibitors [4-3-17/AACR17: #CT159/25, “IFN-y Analysis In Blood & Tissue as a Potential Prognostic and/or Predictive Biomarker” (Sunrise Biomarker #3) http://tinyurl.com/ktzr782 ]. Among a subgroup of 91 patients who are treated with checkpoint inhibitors subsequent to the assigned SUNRISE treatment, MOS was not yet reached for the 45 patients who received docetaxel+bavituximab compared to a MOS of 13mos. for the 46 pts. who received docetaxel+placebo, with a hazard ratio of 0.43 and p=0.005. The statistically significant difference in survival provides strong clinical rationale for combining bavituximab with checkpoint inhibitors. We are encouraged by the positive response received from investigators & thought leaders regarding this subgroup analysis and exploring ways to advance the program as resources permit. In the meantime, as we focus the biomarker analysis on this subgroup of patients, we are seeing some intriguing results and plan to present our findings at key conferences later in the year.

At ASCO in June, we presented addl. supportive data [6-3-17/ASCO'17: "Prelim. Correlative Analysis of PD-L1 Expression from the Sunrise Study” http://tinyurl.com/y93upatl ] demonstrating that patients in the bavituximab containing arm who had low PD-L1 baseline expression on tumor cells, who typically experience poor response to PD-1 or PD-L1 checkpoint inhibitors, led significantly longer than patients with high baseline PD-L1 expression. These data further support the hypothesis that bavituximab may modulate the tumor microenvironment to complement enhance the anti-tumor activity of checkpoint inhibitors.

So the SUNRISE trial database was locked at the end of March of this year. Patients who were still receiving bavituximab at that time were transitioned to compassionate use program and some continue to remain on treatment. We believe bavituximab is active, as some patients have been on treatment for as long as up to 2.5 years and has a good safety profile, making it a useful candidate for combining with other therapies and we remain deeply committed to advancing the growth.

Now, let me provide a brief update in our collaborations, starting with the NCCN trials. At present, 2 of the 3 trials are now opened for enrollment. The 3rd trial at The Sidney Kimmel Comprehensive CC at Johns Hopkins is a Phase II Study of Pembrolizumab & Bavituximab for Recurrent or Metastatic Head & Neck cancer that has progressed on anti-PD-1 therapy, and this trial is expected to be initiated by the end of the year.

Last but certainly not least, our collaborators at MSKCC [Jedd Wolchok Lab] presented a preclinical study at the AACR Annual Meeting which evaluated and compared the anti-tumor activity and side effects of adoptive T cell transfer therapy [“ACT”] in combination with either PS-targeting or anti-OX40 antibodies in mice with advanced melanomas. While PS-targeting and anti-OX40 demonstrated comparable tumor regression when administered in combination with adoptive T cells, only the PS-targeting combination achieved these results without any off-target toxicities. In contrast, the anti-OX40 treatment combination elicited off-target inflammatory side effects. Toxicities have limited the clinical potential of adoptive T cell transfer and CAR-T approaches to-date. The absence of toxicity with PS-targeting in adoptive T cell transfer in this initial mouse melanoma experiment may have important future implications for combination strategies and solid tumors.

I’ll wrap up by saying how excited we are about these recent clinical & preclinical findings, which really set the stage for combining bavituximab with other immunotherapies and we look forward to providing updates on our progress over the coming months.

PAUL LYTLE (CFO): [4-30-17 10K iss. 7-14-17: http://tinyurl.com/ycxu4l5n ]
Let me switch gears now to discuss our financial results for the qtr and full FY17. Our overall guidance this past FY focused on increasing revenue from our contract mfg. business, Avid, while also reducing our spending on R&D, as we seek to position the company closer to overall profitability. During FY17, we achieved both a substantial increase in revenue and a significant reduction in R&D expenses. Let me first talk about top line revenues. Contract mfg. revenue for Q4/FY17 was $17.9mm and $57.6mm for the full FY, representing 30% yr-over-yr growth. And while we missed the low-end of our revenue guidance of $60mm, we were ready to ship approx. $10mm in mfg. revenue at the end of the FY that was unfortunately delayed due to events outside Avid’s control. This revenue will now be shifted from FY17 into FY18.

Regarding our revenue guidance, as Steve mentioned earlier, we currently expect revenue in FY18 to remain consistent with FY17. As temporary production roles are a common part of the CDMO industry, it emphasizes the need to continually expand & diversify our customer base. During FY16 and prior to the Myford facility being built, we had minimal available production slots in our Franklin facility to offer to new customers, and therefore, we had historically limited abilities to diversify our customer base. And as we built and commissioned the state-of-the-art Myford facility in March of 2016, diversifying our customer base was a key focus. We immediately secured one new customer that has completed process validation at Myford and we have recently signed project work for 4 new customers, including one project that is in late-stage development. Based on our current book of business, we are providing FY18 revenue guidance of $50-55mm, which is consistent with the revenue projections we made at this time last year. This projection is based on current information and is supported by current revenue backlog of approx. $58mm under signed contracts, most of which we expect to recognize during FY18.

I’ll now address our efforts to reduce overall spending on R&D. As we announced last June, our internal drug development strategy has shifted away from large late-stage clinical trials to small, cost effective, early-stage clinical trials designed to attract potential partners to further advance our products. Our goal in adopting the strategy was to further reduce R&D spending by 50% in FY17 vs. FY16. We’re pleased to report that our R&D expenses declined 52% over the same prior year period exceeding our targeted reduction. Although we have generated some of the most promising bavituximab data to-date as Steve and Joe just covered, we’re still expecting to further reduce R&D spending by 40% or more in FY18, unless we can secure addl. funding to further advance this program in connection with exploring the various strategic options, including a possible separation of our 2 distinct businesses. In summary, the increase in mfg. Revenue, combined with a decrease in R&D spending, has translated into a reduction in our net loss by 56% for the qtr and 49% for the full FY17 vs. the same prior year period.

Switching gears now, I’d like to provide a quick update on the recently effected reverse stock split [1:7 eff. 7-10-17]. As I outlined during the Q3 earnings call, Peregrine was committed to taking the necessary steps to preserve its NASDAQ listing. While we executed this R/S as a last resort, we firmly believe that doing so was in the long-term interest of our stockholders. To maintain our continued listing on NASDAQ Capital Market, our min. closing bid price has to close at or above a $1 for 10 consecutive trading days. As of the close today, we are now 5 days into that process with a min. closing bid of $1 or higher. This concludes my financial overview.

Q&A: [beg. 20:30]
1. Kumara Raja - Noble Life Science Partners http://noblelsp.com/research
KR: ”Given that revenues are going to be flat comparatively yr-over-yr, how should we think about expenses, ways of reducing R&D expenses? And also costs were higher. When do you expect margins to start getting better?”
Steve King: As revenues fluctuate, we have to watch the costs associated with both the biomanufacturing business as well as our R&D expenditures. If you look at this year’s R&D budget, it is even significantly down from last year. So that that’s going to be further cost savings on the R&D side. Of course, that’s kind of counterintuitive, given the fact we have some really exciting data coming out. Thats one of the reasons we’re looking at the strategic alternatives is really feel like we should be putting more money into R&D, not taking more money out of it, but we also have to deal with financial realities of today, and so we’ll make those adjustments as we go along. But, our goal is to find a strategic alternative that will allow us to move the R&D sort of forward independently of the Avid business. On the Avid side as far as cost of goods go, part of that was bringing on board the Myford facility. So last year, even though we did obviously some nice business in the facility and it’s been busy since day one, it’s still not running at full capacity when you do the process validations, they’re a little bit more cumbersome, a little bit more complex, so there’s more costs associated with those runs. As we get into more full utilization of the facility in kind of campaign mode, where you’re running multiple runs of the same product simultaneously, we’ll see those cost of goods come down, because they simply get spread out over more runs. We’re constantly looking at the business adjusting the expenses in order to continue to have a profitable biomanufacturing business and also to watch your overall corporate finances.
KR: And in terms of making a strategic decision in terms of separating the mfg. vs. the clinical trials business, what are you all thinking in terms of the timeline for making such a decision? And what kind of challenges and opportunities do you see there? Also, on on the clinical data presented at ASCO, obviously, you guys are seeing that patients who had low PD-1 expression, they are surviving longer. For these patients, what treatments are there on after moving from bavituximab? Are there on any other treatments, or are they just continuing on bavituximab?”
Joe Shan: The ASCO presentation you referred to was analysis done on a subset of patients selected by whether or not we had tumor tissue to evaluate the PD-L1, and that ended up being relatively small percentage of the total number of patients enrolled in the SUNRISE trial. We’ve not dissected that small number of patients further by what treatment they went on after SUNRISE trial. So…
Steve King: Most of the patients that did receive the subsequent immunotherapy, it was all primarily PD-1 inhibitors, probably all primarily Opdivo, given the timing as far as that subset, but the rest of the data, as Joe said is – can certainly [ph] as small numbers. On the opportunities for the businesses as far as the kind of the process, I think, it is a process. Obviously, there’s a lot of considerations that you can imagine that need to be taken into account, as we’re looking at different structures that might work and thinking about all those avenues. There’s things such as taxes, where we have to think about. There’s the overall net operating losses of the company that we want to make sure we get full utilization of. So there’s just a lot of complexities. So we don’t currently have a particular timeline we’re marching to. I would say, we will diligently move forward the thinking process and at the appropriate time, we’ll update as we get closer and closer to be in a position to have a clear direction.
Paul Lytle: And Kumar, looking at a number of potential opportunities, so which type of opportunity that we move forward with will basically dictate the timeline.

2. Andrew De Silva (B. Riley & Co.): http://brileyco.com/research
AS: ”On Avid’s committed contracts thus far to-date, do you have a sense as when some of these higher revenue periods should hit? Will they smooth out or be lumpy like it was last year in your opinion? And, what needs to take place for you to get closer to the 40-50% GM% range?”
Paul Lytle: Overall, the CDMO business generally has lumpy revenue streams, because you have a mix of customers, sometimes they’re in an earlier stage and they do a few mfg. runs and then they go away for a while and they come back for the next set of runs. And then you have commercial supply, where it can go up and down depending on the product and the launch and the timelines of your commercial customers. With respect to our particular lumpiness, we’ve had issues with our third-party vendors, where we have delays in testing over the last FY year that caused some lumpiness in our revenue streams. So our goal is to expand & diversify our customer base. The more customers we have in the mix, the less lumpy the revenue streams would be. We also want to make sure we secure good commercial customers, like the ones we have today, that that do provide kind of a consistent consistent need for manufacturing. The more diversified you can get and more commercial you can get, the less lumpiness you’ll see in future revenues and that’s our kind of our goal moving forward. I think we’re going to see some lumpiness in terms of FY18, but as our customers submit their BLAs and go through the commercial launch & inventory builds that Steve mentioned earlier, I think you’ll see less lumpiness going forward in the FY19 time period.
AS: Is it still too early for you guys to get a sense of what the quarterly impact might be this year from a seasonality standpoint?”
Paul Lytle: Yes, it’s a quite complex in terms of timing and lot release. As we mentioned in the script, we had $10mm in revenue that was expected to ship by the end of April, and due to unforeseen events that were outside our control, that now has shifted into FY18, so that’s a large lumpy number.
AS: ”re: R&D, you mentioned that that should continue to decline yr-over-yr. I’m just kind of curious how does that work now that you’re expected to start a Phase II trial [NCCN/Head+Neck] in the back-half of this FY?”
Steve King: At this point we haven’t committed to starting new studies. The only new studies that we’ve committed to are the NCCN studies, which were all funded under a $2mm grant. Those are the only ones we are really committed to, and in order to start new studies beyond that, it’s one of the reasons that we’re looking at the strategic alternatives for the company, because I think in order to do that, we need to raise dedicated funding for that. At the same time, we recognize that for the Avid business continue to grow, we should raise dedicated funding for that business, in order to add on to our capabilities to upgrade some of our capabilities and then to add on more capacity at the right time. So, right now it’s sort of status quo as we move forward on the R&D front, and as we’re able to really have a clearly defined pathway forward for the R&D business with the appropriate funding, then I know our group already has some plans of what could be the next study designs.
Paul Lytle: The Phase II that you alluded to that that does fall under our $2mm NCCN grant, some of which was paid last FY year and then there’s some being paid this FY. But that covers 3 trials being run by this NCCN consortium.
AS: ”So there shouldn’t be too much of an impact then as we go through the year unless you guys decide to be more aggressive or able to get the adequate funds?”
Paul Lytle: Correct.
AS: ”You talked about potential strategic relationships and you have a preclinical collaboration with Sloan Kettering. Can you elaborate how that collaboration gets extended into a clinical work? And then how it works when you tie into a strategic partner? Does that all have to be rehashed out, or are there some covenants in there that make that a simple process?”
Steve King: One of the goals of the group is that Sloan Kettering is to directly translate what they’re doing on the preclinical front into clinical studies at the institution. And so, they typically only want to work on things that they have that opportunity for. If we think about the possibility of bavi in combination with CAR-T therapy, then we would expect that once they’ve generated the right amount of data then we would have a discussion with obviously one of the CAR-T companies about collaborating on moving that forward under the umbrella of the group there at Sloan Kettering. We’re working with probably the top immunology lab [Jedd Wolchok’s Lab] when it comes to the development of immune checkpoint inhibitors there, and they have very, very tight clinical connections. Jedd Wolchok obviously is the head of the lab there and he’s very well connected. So, we would expect actually that some doors can open through the collaboration and through the introductions, because we know the clinicians at Sloan Kettering already work with all the major pharma, and so there are already good connections there that can help really hopefully expedite those into clinical development.
AS: ”Does it have to be CAR-T, or other immuno-oncology optionalities open as well, or are you kind of just focused strictly on that vertical right now?”
Steve King: That’s [CAR-T] is one of their favorite projects, so they’ve really been excited about the data, because if you look at the results were presented, it’s really the ability of bavituximab to enhance the activity of the adoptive T cell therapy vs. the lack of any additional toxicity. And, when they compared it with an agent like OX40 that actually also increased activity, but also had more safety events, then they really like that approach. But no, this could extend to PD-1/PD-L1 probably quite a number of other molecules that there’s an interest in. So, there’s a lot of interest across the board, because as the field is maturing and more results are coming out, you’re running into two things. One is, drugs just don’t work well together either from a safety standpoint or there’s no enhanced efficacy, and we’re seeing more & more of that reported. I think there’s a real window of opportunity here. In addition, you have patients that are on treatments that develop a resistance to the therapies, and that opens up another door for, based on the mechanism of action for bavi, to potentially reinvigorate the ability of the PD-1/PD-L1 inhibitors. The Sloan Kettering Group, there are quite a number of actual researchers that are working on it, each of which are looking at different aspect. CAR-T and adoptive T cell is just simply one of those.

MR. KING’S CLOSING COMMENTS:
I’d like to thank you all again for participating in today’s phone call. As always, I want to thank you, our stockholders, for your continued support, and I would like to specially thank our patients, their families and the investigators that are participating in our bavituximab clinical trials. With that, we will conclude the call.

7-14-17/PR: Peregrine Pharmaceuticals Reports Financial Results for Quarter and FY Ended April 30, 2017 and Recent Developments
**Avid Achieves Year-Over-Year Topline Revenue Growth of 30% Exceeding $57 Million
**Overall Survival in Phase III SUNRISE Subgroup Receiving Subsequent Immune Checkpoint Inhibitors
**Recent Presentation Supports Bavituximab's Potential to Improve Clinical Outcome for Immune Checkpoint Inhibitors
http://ir.peregrineinc.com/releasedetail.cfm?ReleaseID=1033237
TUSTIN, July 14, 2017: Peregrine Pharmaceuticals, Inc. (NASDAQ:PPHM/PPHMP), a biopharmaceutical company committed to improving patient lives by manufacturing high quality products for biotechnology and pharmaceutical companies, and advancing its proprietary R&D pipeline, today announced financial results for the fourth quarter and fiscal year (FY) ended April 30, 2017, and provided an update on its contract manufacturing operations, research and development programs, and other corporate highlights.

Highlights Since January 31, 2017
"We are very pleased to announce that the business recorded its highest annual revenue to date during fiscal 2017," stated Steven W. King, President & CEO of Peregrine, and President of Avid Bioservices. "While we are happy to report continued year-over-year revenue growth, we are projecting revenues for FY 2018 to be similar with FY 2017 due to recent changes in the forecast of a large customer and a delayed regulatory filing for another customer. We believe this is a temporary lull and remain confident that Avid is in a strong position for continued growth in the future." Mr. King continued, "An important part of continuing revenue growth and reducing risk for the business is to attract new customers. On that front, we have recently signed four new customers that we expect to contribute to top-line revenue in FY 2018 and into the future. In addition, we successfully completed three process validation campaigns this fiscal year for existing third-party customers which we believe may significantly contribute to future revenue as these customers move toward building inventory for their potential launch, and commercial supply.
"We are also continuing to take other important steps to ensure Avid's growth in the coming years. As part of this effort, we have recently installed two new 2,000 liter bioreactors in our Myford facility, and we already have commitments for part of this capacity. Due to its state-of-the-art and modular design, there remains potential to install additional bioreactors in Myford, which will allow us to continue growing the business within our current facilities.

"Turning to the Peregrine business, we were able to generate some of the most compelling bavituximab data to date, further supporting the combination of bavituximab and checkpoint inhibitors even while reducing R&D spending by over 50% in FY 2017. The clinical findings came from the comprehensive analysis of maturing Phase III SUNRISE data while impressive preclinical results came from our collaborators at Memorial Sloan Kettering Cancer Center (MSKCC). The researchers at MSKCC presented promising preclinical data combining PS-targeting with adoptive T cell transfer therapy which may support the combination of bavituximab with CAR-T cell immunotherapy in the future.

"Both Peregrine and Avid have achieved important milestones in recent quarters. The success of Avid and its continued revenue growth with the compelling data we have seen from the Phase III SUNRISE trial have led us to explore various strategic options that we believe will enable us to enhance stockholder value for all stockholders, including the possible separation of these two distinct businesses."


Research and Development Highlights
"The most compelling data to date from the Phase III SUNRISE trial was presented at AACR and together with the PD-L1 results presented at ASCO this year add to the growing body of data supporting the further development of bavituximab with checkpoint inhibitors," said Joseph Shan, VP of Clinical & Regulatory affairs at Peregrine.

AACR Highlights:
In a subgroup analysis, Peregrine researchers looked at the outcome of 91 patients that were enrolled in the Phase III SUNRISE trial that were subsequently treated with anti-PD-1/PD-L1 immune checkpoint inhibitors ("ICI's") post study treatments. The results from this analysis demonstrated that the patients who received docetaxel plus bavituximab (Doc+Bavi) and subsequent ICI had not yet reached median overall survival ("mOS") compared to mOS of 13.0 months for patients who received docetaxel plus placebo (Doc+Placebo) (hazard ratio [HR], 0.43; p=0.005). The statistically significant difference between the two arms in the trial provides strong rationale for combining bavituximab with ICI's and supports the hypothesis that bavituximab may modulate the tumor microenvironment to enhance the anti-tumor activity of ICI's.
A photo accompanying this announcement is available at http://www.globenewswire.com/NewsRoom/AttachmentNg/428c1a61-a599-4976-8a92-d65148671bcd


ASCO Highlights:
Peregrine researchers presented additional supportive data demonstrating that patients in the bavituximab containing arm who had low baseline PD-L1 expression on tumor cells (i.e., patients typically with poorer response to PD-1/PD-L1 checkpoint inhibitors) lived significantly longer than patients with high baseline PD-L1 expression. These data further support the hypothesis that bavituximab may modulate the tumor microenvironment to complement and enhance the anti-tumor activity of ICI's.

NCCN Highlights:
The three clinical trials under the collaboration with the NCCN are advancing as planned.

Massachusetts General Hospital Cancer Center - Phase I/II Clinical Trial of Bavituximab with Radiation and Temozolomide for Patients with Newly Diagnosed Glioblastoma. This trial is open for enrollment.

Moffitt Cancer Center - A Phase I Trial of Sorafenib and Bavituximab Plus Stereotactic Body Radiation Therapy for Unresectable Hepatitis C Associated Hepatocellular Carcinoma. This trial is open for enrollment.

The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins - Phase II Study of Pembrolizumab and Bavituximab for Progressive Recurrent/Metastatic Squamous Cell Carcinoma of the Head and Neck. This trial is expected to be initiated by the end of the calendar year 2017.

Preclinical Highlights:
Researchers from Memorial Sloan Kettering Cancer Center (MSKCC) presented a preclinical study evaluating the anti-tumor activity and toxicities of adoptive T cell transfer therapy in combination with either PS-targeting antibodies or anti-OX40 antibodies in mice with advanced melanomas. Whereas PS-targeting and anti-OX40 demonstrated comparable tumor regression when administered in combination with transferred adoptive T cells, only the PS-targeting combination achieved these results without any off-target toxicities. In contrast, the anti-OX40 treatment combination triggered off-target side effects.

PS Exosome Technology Highlights:
The company continues to make progress with its PS exosome diagnostic technology that is designed to detect and monitor cancer. The assay has been successfully optimized and we are currently preparing to generate additional data by testing human samples. Such data will be important to partnering discussions.

Avid Bioservices Highlights
"FY 2017 was a strong year for Avid Bioservices with year-over-year revenue growth of 30% compared to FY 2016. The company recognized revenue of $17.9 million for the fourth quarter and $57.6 million for the full fiscal year," stated Paul Lytle, CFO of Peregrine. "While we missed our revenue guidance of $60-65 million, we were ready to ship a number of process validation runs which were delayed due to events outside our control. This delay has caused approximately $10 million in manufacturing revenue to shift from fiscal year 2017 to fiscal year 2018."

The company is providing manufacturing revenue guidance for the full FY 2018 of $50-55 million.

Avid's current manufacturing revenue backlog is $58 million, representing estimated future manufacturing revenue to be recognized under committed contracts. Most of the backlog is expected to be recognized during FY 2018.

Financial Highlights and Results
During the fourth quarter of FY 2017, we recorded total revenues of $17,904,000 as compared to $18,783,000 in the fourth quarter of the prior FY. For FY 2017, we achieved total revenues of $57,630,000 as compared to $44,686,000 for FY 2016. This represents total revenue growth of 29% for FY 2017 compared to the same prior year period.

Contract manufacturing revenue from Avid's clinical and commercial biomanufacturing services was $17,904,000 for the fourth quarter of FY 2017 compared to $18,783,000 for the fourth quarter of FY 2016. For the year, revenue increased 30% to $57,630,000 for FY 2017 compared to $44,357,000 for FY 2016. The fiscal year increase was primarily attributed to an increase in demand for contract manufacturing services associated with process validation activities. Current committed manufacturing backlog for Avid is approximately $58 million, covering services to be provided during FY 2018 and into FY 2019. Based on this current backlog, Peregrine expects contract manufacturing revenue for FY 2018 to be between $50 and $55 million.

Total costs and expenses for the fourth quarter of FY 2017 were $23,208,000, compared to $30,698,000 for the fourth quarter of FY 2016. For FY 2017, total costs and expenses were $85,890,000 compared to $101,046,000 for FY 2016. For the fourth quarter of FY 2017, research and development expenses decreased 59% to $6,717,000, compared to $16,265,000 for the fourth quarter of FY 2016. For FY 2017, research and development expenses decreased 52% to $28,297,000 compared to $59,529,000 for FY 2016.

Cost of contract manufacturing increased to $11,782,000 in the fourth quarter of FY 2017 compared to $9,721,000 for the fourth quarter of FY 2016, and to $38,259,000 for the full FY 2017 as compared to $22,966,000 for the full FY 2016. These increases are primarily due to an increase in the cost of contract manufacturing associated with higher reported revenue. Also contributing to this increase and impacting gross margins for the period is the higher overhead cost of operating the new Myford facility as well as higher labor cost associated with performing process validation runs combined with lower utilization of available capacity. For the fourth quarter of FY 2017, selling, general and administrative expenses decreased slightly to $4,709,000 compared to $4,712,000 for FY 2016. For FY 2017 selling, general and administrative expenses increased to $19,334,000 compared to $18,551,000 for FY 2016. The full-year increase is primarily due to the company's growing manufacturing business.

Peregrine's consolidated net loss attributable to common stockholders was $6,714,000 or $0.16 per share, for the fourth quarter of FY 2017, compared to a net loss attributable to common stockholders of $13,264,000, or $0.40 per share, for the same prior year quarter. For FY 2017, net loss attributable to common stockholders was $32,799,000, or $0.88 per share, compared to $60,136,000, or $1.95 per share, for FY 2016.

Peregrine reported $46,799,000 in cash and cash equivalents as of April 30, 2017, compared to $61,412,000 at fiscal year ended April 30, 2016.

More detailed financial information and analysis may be found in Peregrine's Annual Report on Form 10-K, which will be filed with the Securities and Exchange Commission today. [ http://tinyurl.com/ycxu4l5n ]

**4-30-17 10K/p.33: “Excluding any future potential new business, we expect Avid revs for FY18 to slightly decline vs. FY17. Part of this decline is due to lower anticipated commitments from Halozyme (our largest customer) based on their most recent committed forecast (covering the 3 qtrs ending March 2018), which amount is expected to be partially offset by $10mm revenue that was expected to be recognized in FY17, but has been shifted to FY18 due to a delay in shipping product that was complete and ready for shipment as of fye 4-30-17. http://tinyurl.com/ycxu4l5n

*The 10-Q’s define OPER.BURN as, ”Net cash used in operating activities before chgs. in operating assets & liabilities”.
The 7-21-2001 10Q explains OP.BURN very nicely:
“RESULTS OF OPERATIONS. Before we discuss the Company's total expenses (cash & non-cash expenses), we would like to discuss the Company's operational burn rate (cash expenses used in operations, net of interest and other income) for q/e July 31, 2001 compared to the same period in the prior year. The operational burn rate is calculated by taking the net income (loss) from operations and subtracting all non-cash items, such as the recognition of deferred license revenue, depreciation and amortization and stock-based compensation expense.”
