More on Shionogi’s COVID trial:
https://www.fiercepharma.com/pharma/shionogis-homegrown-antiviral-comes-short-global-covid-trial
Notably, the article cites Shionogi’s CEO saying that Xocova could generate $2B of annual sales if approved in the US. It’s unclear how much of this hypothetical sales figure comes from COVID patients who would otherwise have taken Paxlovid vs COVID patients who would otherwise have taken no drug.
My take is that they missed the primary end point and are on the edge of the long-Covid data so are extending the trial to see if they can at least hit the reduction in the incidence of long Covid.

What are the benefits of pyrrolidine?
Pyrrolidines are very important nitrogen-containing heterocycles. It has glucosidase inhibitory activity, along with antiviral, antibacterial, antidiabetic, and anticancer activities.
Analyst Ed Arce of H.C. Wainwright maintained a Buy rating on Enanta Pharmaceuticals (ENTA – Research Report), reducing the price target to $27.00.
Ed Arce has given his Buy rating due to a combination of factors, including Enanta Pharmaceuticals’ promising developments in its RSV (respiratory syncytial virus) franchise. The anticipation of top-line data readouts from two key Phase 2 studies of their lead RSV program, zelicapavir, in the second half of 2024 is a significant driver. The enrollment progress in these studies, especially with one part fully enrolled and the other advancing, reflects positively on the company’s ability to execute its clinical trials. The high potential of zelicapavir in at-risk populations, including children and adults with RSV complications, underscores the market opportunity for Enanta’s product.
Additionally, the upcoming data from a Phase 2a challenge study of EDP-323, another oral RSV candidate with a different mechanism, enhances the company’s RSV pipeline strength. This candidate’s potential efficacy in combination with other RSV therapeutics offers a strategic advantage. Arce also considers the progress in Enanta’s immunology program, particularly the KIT inhibitor candidate for chronic spontaneous urticaria (CSU), which the company expects to select for clinical development by the fourth quarter of 2024. The innovative approach targeting the depletion of mast cells to treat CSU could address a significant unmet medical need, further justifying the positive outlook on Enanta’s stock.
In another report released today, JMP Securities also reiterated a Buy rating on the stock with a $22.00 price target.

Hi, this is Tina on for Lisa. And I have a question on the 323 program. What doses of two three are you testing in Phase IIa human challenge study?
Jay Luly
Yes, so we're looking at a couple of different dose regimens. So the first it's 600 milligrams straight across for five days. And the other is 600 milligram loading dose on day one, followed by 200 milligrams on each subsequent day.
I had second question on the patent against the case against Pfizer because loss created by this setback exclusive, it doesn't infringe the patent because it has high floral growth, which is not described in York PATTY. So if you can comment on that?
Support for R15 as fluorine substituted tert-butyl is found specifically in the specification in column 69, lines 61-64: “The term “substituted” refers to substitution by independent replacement of one, two, or three or more of the hydrogen atoms with substituents including, but not limited to, —F, —Cl, —Br, —I, —OH, …”
Also, the following text in specification in column 7, lines 45-48: “Preferably, A has 0, 1 or 2 substituents.Preferably the substituents are independently selected from fluoro, chloro, hydroxy, methoxy, fluoromethoxy, difluoromethoxy, and trifluoromethoxy” clearly implies the intention of the A group having trifluoromethoxy.
Enanta Pharmaceuticals to Participate at the JMP Securities Life Sciences Conference
WATERTOWN, Mass.--(BUSINESS WIRE)--May 7, 2024-- Enanta Pharmaceuticals, Inc. (NASDAQ:ENTA), a clinical-stage biotechnology company dedicated to creating small molecule drugs for virology and immunology indications, today announced that Jay R. Luly, Ph.D., President and Chief Executive Officer, and Tara L. Kieffer, Ph.D., Chief Product Strategy Officer, will participate in a fireside chat at the JMP Securities Life Sciences Conference on May 14, 2024 at 10:00 a.m. ET in New York, NY.

ENTA updated corporate slides (5/6/24)
https://ir.enanta.com/static-files/0b9a9564-339c-4501-8c98-eab636846bf4
The latest version of the slide set is almost identical to the previous version (from 3/13/24); the differences are:
• Slides 3 and 7 have updated financial info from FY2Q24 (ending 3/31/24).
• Slide 37, which shows 2024 news flow, has two small changes: 1) Data from the Zelicapavir (f/k/a EDP-938) RSVPEDs study is expected in 2H24 rather than 3Q24; and 2) Selection of a lead candidate in the CSU program is expected in 4Q24 rather than simply 2024. There is no specific guidance on the timing of topline data from the RSVHR study, which is recruiting patients in the Southern Hemisphere.
ENTA reports FY2Q24* results—raises FY2024 expense guidance:
https://ir.enanta.com/news-releases/news-release-details/enanta-pharmaceuticals-reports-financial-results-its-fiscal-39
• 3/31/24 cash = $300.3M, a decrease of $37M relative to 12/31/23.
• FY2Q24 royalty revenue was $17.1M, -10% QoQ and -4% YoY. 54.5% of ENTA’s Mavyret royalties are payable to OMERS (Canada’s largest pension fund), and this amount is treated for accounting purposes as an amortization of debt (see discussion in #msg-172603887).
• FY2Q24 R&D expenses were $35.6M, consistent with ENTA’s updated fiscal-year guidance of $125-145M (raised from the $100-120M guidance given in Nov 2023).
• FY1Q24 SG&A expenses were $14.2M, consistent with ENTA’s updated guidance of $50-60M (raised from the $45-50M guidance given in Nov 2023). Legal expenses for the Paxlovid lawsuit against PFE were a material portion of the SG&A expenses for the quarter.
• ENTA says its cash and expected royalty revenue are sufficient to fund operations through the end of FY3Q27, which is one quarter earlier than the prior guidance of end of FY2027.
*ENTA’s fiscal year ends on September 30.
correct PFE completed their phase 2 months ago - it is still listed in their pipeline so it has not been formally killed, and data could just be under wraps for competitive reasons
Yeah for a study that most think will be positive I too am starting to think they may have a miss or at least some mixed data. We will probably know more in the coming days w their earnings

The long Covid endpoints are at 24 weeks in the trial listing but they said more than once they plan to unblind data at 12 weeks so??
“we have completed the enrollment of over 2,000 cases in December 2023. For the primary endpoint, the time to resolution of all COVID-19-related symptoms, all 15 symptoms, was determined after consultation with the FDA. In addition, we have obtained data on the suppression of the incidence of Long COVID, so-called sequelae, at 12 weeks, and we are verifying this as well in SCORPIO-HR trial. We are keeping the data up to three months under blind, so we expect to be able to present our results to you in April on these results as a topline after a three-month follow-up starting in December.”
April came and went with no PR. You would think an outright hit or miss would be a straightforward readout so perhaps they are doing some post hoc data mining? Could also be they decided to keep the trial blinded out to 24 weeks who knows
I concur that Paxlovid 1Q24 sales and 2024 guidance are not surprising; however, I think some investors were confused by PFE's 4Q23 writeoff and didn't realize that the 2023 figure was an accounting artifact rather than a reflection of product demand.
Not sure but I wasn’t surprised by paxlovid sales and think they are lowballing guidance still. They are still the only game in town in western countries although most people think ensitrelvir will be on the market here by early 2025 (although the odds went down a bit IMO when they missed their own guidance for reporting top line data)
Is ENTA getting a delayed bounce from PFE’s $3B 2024 sales guidance for Paxlovid?
This is what Shionogi said on their call Jan 31:

Our team presented “Efficacy and Safety of EDP-235 in Non-hospitalized Adults With Mild or Moderate COVID-19: Results From the Phase 2 SPRINT Study” at
@ESCMID Global where it was named a “Top Rated Poster.” Congratulations to the team.
POSTER CONCLUSIONS
• EDP-235 treatment in standard-risk adults with mild or moderate COVID-19 yielded a favorable safety profile and improvements in clinical symptoms
• EDP-235 was generally well tolerated, as reflected by a low frequency of TEAEs that were mostly mild in severity, and there were no serious TEAEs or
TEAE-related discontinuations
• The 400 mg dose of EDP-235 achieved statistically significant improvement in TSS at multiple time points in the overall study population
– In participants enrolled within 3 days of symptom onset, along with significant TSS improvement at all time points, a median 2-day shorter
duration of 6 selected COVID-19 symptoms was observed
• The rapid decline of viral load across all study groups was consistent with an enrolled population that had prior immunity
• The results of the Phase 2 SPRINT study support further development of EDP-235 for the treatment of COVID-19
• As the therapeutic target is conserved across variants, EDP-235 may prove an effective tool to combat future variants of SAR-CoV-2 and potentially
other coronaviruses

I think maintaining continuity of in-house general counsel would be important during the on-going patent litigation. I also think the experience attained during the term with Enanta would be beneficial to retain during negotiations for Enanta's various technologies -- outsourcing, partnering.
I think maintaining continuity of in-house general counsel would be important during the on-going patent litigation. I also think the experience attained during the term with Enanta would be beneficial to retain during negotiations for Enanta's various technologies -- outsourcing, partnering.
I am quite reasonable and I consider this an untimely and likely disruptive loss which is worthy of acknowledgement thru mention on this board.
Nathaniel Gardiner retired at what could be considered the pinnacle of his career with Enanta, during a high profile lawsuit with Pfizer? Who is your clown?
The case is farmed out to a high profile MA based firm. The in house counsel is not actively managing the case at all
Even Pfizer uses outside counsel to manage a case like this which requires specific expertise which they simply don't keep in house
Gardiner is 71. I don't see anything odd about his retirement.

I never considered a data leak on the RSV drug, but there could be a leak on ensitrelvir data (run by NIH and they have data in hand so could be more leaky than if was strictly managed by shionogi I think) or some happenings in the court case. Most likely of course is that the recent drop is just due to inherent volatility
Right! ENTA updated the guidance for RSVHR reporting on the Leerink webcast on 3/13/24 (the same date as the “new” corporate slide set). The prior “it depends” guidance was from ENTA’s FY1Q24 CC on 2/7/24.
In any event, the salient point is that ENTA is not due to report any clinical data until July at the earliest. This should reassure anyone who may have thought the recent share-price decline was due to a data leak.
ENTA has not yet commented on when it will report data from the Zelicapavir PSVHR trial (for high-risk adults) because that depends on whether enrollment is completed during the current RSV season in the Northern Hemisphere.
ENTA corporate slide set (3/13/24):
https://ir.enanta.com/static-files/0b9a9564-339c-4501-8c98-eab636846bf4
There are no differences between the 3/13/24 slide set and the previous slide set on 2/7/24.
Clinical newsflow reiteration: ENTA expects to report data from the Zelicapavir RSVPEDs trial and the EDP-938 “challenge” trial in 3Q24. ENTA has not yet commented on when it will report data from the Zelicapavir PSVHR trial (for high-risk adults) because that depends on whether enrollment is completed during the current RSV season in the Northern Hemisphere.
Just calling it the way I see it - ENTA does have a potential stake in paxlovid
PFE has been totally silent on their next gen PI for covid - the phase 2 was completed months ago
https://clinicaltrials.gov/study/NCT05799495?term=PF-07817883&rank=5
Regardless negative ensitrelvir data would still be bullish for ENTA because it is bullish for paxlovid which would make any potential settlement in the lawsuit more valuable (and vice versa of course if the ensitrelvir data are good)
The market is upset they are allocating the cost of a plane ticket to Spain and hotel for the presentation. It's a few thousand added burn ;)
Joking aside nice to see the data will be presented - it's the right thing to do even on what seems to be a defunct asset
235 could be revived if ensitrelvir doesn't post positive phase 3 data this month. Regardless negative ensitrelvir data would still be bullish for ENTA because it is bullish for paxlovid which would make any potential settlement in the lawsuit more valuable (and vice versa of course if the ensitrelvir data are good)

Legal Fees for Patent Applications and Patent Defense
The 8-K shows that patent defense legal fees are assigned to General and Administrative Expenses. Are patent application fees assigned to research and development costs? For years I thought Enanta's patent portfolio was a wonderful asset, but now I am wondering if it was an unscrupulous waste of money transferring oodles of cash from Enanta to their legal counsel. Kickback and enjoy. Capisce?

one must be able to describe the thinking and process one takes to create that molecule- if one is to defend their IP.
Thanks for your comments re:patents. Seems ENTA is flush with patents protecting their small molecule discoveries. It would make "cents" to have their discoveries certified & protected by their string of patent attorneys. **Pfizer - watch out!
**
I rather enjoy the updates on Enanta's being issued patents.
I long for the day that these will mean something palpable in it's share price.
I hold (or is it merely wishful thinking?) that a company that is centered on discovering molecules MUST have a branch that can rigorously defend those patents, that's skilled at filing patents. It isn't enough to merely create them after, one must be able to describe the thinking and process one takes to create that molecule- if one is to defend their IP.
I say this as Enanta's lawsuit progresses with Pfizer and hope that they have done the work required to successfully defend their IP.
They keep comin' !

As impressive as this rise in ENTA stock price over this week (from $14 to $17.41), its market cap is still only $370 million. That means any solid positive news could drive a major price spike.
Not sure. Wish I have more money here than that damn RVNC. lol
I hesitate to post this but I'm going to include a link, a chart.

We've been in an uptrend and when I see a huge spike, or series of large spikes they are often followed by a selloff.
How well I know that lesson. : (
Maybe Enta will go up, and up.
BUT particularly if this is just a large day or a series of large days anyone just (or pondering) getting in should realize that someone is going to take profits.
IE, runups are often precursors to selloffs.
