$NVAX -- They have some pivotal data coming up on their H1N1 candidate. They are also waiting on a sizable grant from BARDA that was supposed to come last year but I guess you can't count on the govt to deliver in a timely manner on such things.
$IBIO -- They have a really interesting technology for vaccines, like PLX, that is based on using plants. I think people overlook them so easily because of how small they are, but the Bill and Melinda Gates Foundation appear to be seriously interested in using their technology. I would not underestimate the potential just yet. I highly doubt their foundation did not thoroughly vet them.
$CBLI -- This is more of a bet on the govt's need to stockpile. In regards to the animal studies, I'm not sure about how ethical it is to give people acute radiation syndrome in order to test their treatment for on people. CBLB502 is being developed by Cleveland BioLabs under the FDA's Animal Efficacy Rule. It also has potential for use in patients receiving total body irradiation.
They secured a $45m($15m upfront) BARDA contract and more Federal money is on the way, due to the Project Bioshield Act. Other countries will probably follow once the US puts more money in.
$AMRN -- I give about 80% chance that the ANCHOR study is positive. I have reviewed the Japanese data where they conducted a similar trial and produced significant results in those with TG between 200-499mg. AMR-101 seems like a product a number of parties will be interested in.
$PLX -- Fairly certain their Gaucher's treatment, Uplyso (taliglucerase alfa), will be approved on 2/25. It's a plant-cell based protein technology that has a lot of promise, especially they get approval. I think they will be able to compete with Cerezyme because Uplyso is MUCH cheaper to manufacturer, hence they can sell it at a considerable discount to Cerezyme. Obviously, it will be tough getting people to switch, but a good number have already been using their treatment because of Genzyme's manufacturing woes. They are also developing an oral version for Gauchers.
$SGEN -- I don't think Pazdur's recent comments have any effect on them. Their response rates are VERY high, small pat. population and lots of activity.
[Does anyone have any comments on these results? They sound good on the surface but just curious if there are any red flags in the data or if it's simply too soon to get a read on whether the vaccine will work. Are there any competitive threats out there from big pharma or otherwise in this space? This is apparently an unmet medical need and a large market opportunity.]
NOVAVAX Reports Positive Results From Phase I Trial of Respiratory Syncytial Virus Vaccine Candidate
Press Release Source: Novavax, Inc. On Monday October 3, 2011, 8:00 am EDT
- Well-tolerated with no systemic side-effect trends - Highly immunogenic with an increase in anti-RSV antibodies in 100% of subjects in the highest-dose group - Oral and poster presentations to be made at 5th Vaccine and ISV Annual Global Conference in Seattle
ROCKVILLE, Md., Oct. 3, 2011 (GLOBE NEWSWIRE) -- Novavax, Inc. (Nasdaq:NVAX - News) today announced positive top-line results from a Phase I clinical study of its respiratory syncytial virus (RSV) fusion (F) recombinant nanoparticle vaccine candidate. In a paper titled "Recombinant RSV F nanoparticle vaccine for respiratory disease: antigen characterization, preclinical efficacy and clinical evaluation," Gregory M. Glenn, M.D., Senior Vice President and Chief Medical Officer of Novavax, is presenting safety, immunogenicity and tolerability findings from this study in a poster and oral presentation today and tomorrow, respectively, at the 5th Vaccine and ISV Annual Global Conference in Seattle. In the United States, RSV is the most common cause of bronchiolitis and pneumonia in children under 1 year of age resulting in 90,000 to 147,000 hospitalizations in this age group. Additionally, 900,000 adult and elderly patients are hospitalized annually due to RSV infection in the United States and Europe.
Novavax initiated the blinded, placebo-controlled, dose-escalating Phase I trial in December 2010 to assess the safety and tolerability of aluminum phosphate-adjuvanted (adjuvant) and unadjuvanted formulations of its RSV vaccine candidate. A secondary objective of the study was to evaluate total and neutralizing anti-RSV antibody responses and assess the impact of the adjuvant. The study enrolled 150 healthy adults 18 to 49 years old who were allocated to six cohorts that included 4 dose levels of vaccine. The two highest dose levels were formulated with and without the adjuvant. Subjects were randomized to receive injections of vaccine or saline placebo in a 4:1 ratio on days 0 and 30. Immune responses were evaluated in blood samples taken on days 0, 30, and 60.
"The results from our first RSV in-human study are very encouraging and support expanded testing of this vaccine candidate to those most affected by RSV infection, infants and children, and adults age 65 and older," Dr. Glenn said. "Our findings from this Phase I trial are consistent with our preclinical results in relevant animal models, which indicated that our vaccine candidate was generally well-tolerated, highly immunogenic and produced functional antibodies that neutralized RSV. In the same preclinical studies, the vaccine was fully protective against live-virus challenge, indicating that such measures of immunity are associated with protection. RSV disease is a major unmet medical need and a priority target for vaccine developers, and the results from this trial represent an important step towards reaching the ultimate goal of a safe and effective vaccine."
In his presentations, Dr. Glenn is reporting that Novavax's RSV vaccine candidate was well-tolerated and highly immunogenic, inducing levels of functional immunity that could potentially correlate with protective immunity in future trials. The fusion (F) antigen used in the Novavax RSV vaccine candidate is common to all RSV strains. Antibodies against the F antigen are known to prevent RSV disease in premature infants using the injected monoclonal antibody Synagis(R) (palivizumab), the current standard of care for RSV prophylaxis in premature infants. The data seen in this trial indicate that the Novavax RSV vaccine candidate induces immunity similar to natural protective immunity, as well as induces responses against the specific molecular target of Synagis on the F protein. Together, these data suggest that the vaccine may hold promise for prevention of RSV illness.
The primary safety findings were local pain and tenderness at the site of injection, the majority of which were mild in nature with no dose-related increase observed. There were no observed vaccine-related serious adverse events or trends for related systemic side effects. The antibody response to the RSV F protein was significantly increased compared to placebo (p<0.001) in all groups and increased by 19 fold in the highest-dose group at day 60. A significant dose-response pattern was observed. High rates of seroconversion were seen at all doses including a rate of 100% at the highest-dose-adjuvant group. Plaque reduction neutralizing titers (PRNT) were also measured and were significantly higher (p<0.01) in all the vaccine groups containing adjuvant. Exploratory measures of the vaccine-generated immunity specific to the Synagis epitope on the RSV F protein indicated that the vaccine induced significant increases (p<0.0001) compared to placebo in all groups.
Stanley C. Erck, President and Chief Executive Officer of Novavax, stated: "I congratulate my colleagues and our clinical investigators on these impressive results which will allow us to continue to pursue the development of a vaccine to prevent RSV infection. There remains an urgent public health need for such a vaccine, as none exist today and current treatments for RSV are expensive, difficult to administer and of limited benefit. We believe our vaccine candidate shows great promise as a potential prophylactic against RSV lower respiratory tract illness. The clinical data from this trial now provides a pathway for us to aggressively move forward in studying this vaccine candidate in infants, young children and older adults who represent the populations most affected by RSV."
About Respiratory Syncytial Virus
RSV is the most important viral cause of lower respiratory tract infection in infants and children worldwide. The global disease burden is estimated at 64 million cases and 160,000 deaths every year. RSV is the most common cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia in children under 1 year of age in the United States. Each year, 90,000 to 147,000 children in this age group are hospitalized due to RSV infection. Almost all children will have had an RSV infection by their second birthday. When infants and children are exposed to RSV for the first time, 25% to 40% of them have signs or symptoms of bronchiolitis or pneumonia, and 0.5% to 2% will require hospitalization. Most children hospitalized for RSV infection are under 6 months of age. Additionally, wheezing illnesses caused by RSV, particularly those severe enough to lead to hospitalization, are associated with an increased risk of asthma at school age.
It is also estimated that more than 8.5 million adults, including the elderly over age 65 years, are infected and 900,000 patients are hospitalized annually due to RSV infection in the United States and major European countries. In the United States alone there are 177,500 hospitalizations among high-risk adults resulting in annual medical costs exceeding $1 billion. There is currently no approved vaccine for the prevention of RSV.
