SAB Biotherapeutics: Influenza, COVID-19 Candidates Show Broad Efficacy Against Variants

 SAB Biotherapeutics Inc 

 presented an overview of its DiversitAb polyclonal platform at the 2022 Plasma Product Biotechnology Conference.

The company said the DiversitAb platform can produce natural, specifically targeted, high-potency, fully-human polyclonal immunotherapies against various disease targets without human donors.

The company also outlined data on SAB-185 for COVID-19 and SAB-176 for seasonal and pandemic influenza showing the candidates being effective against variants of several highly mutating viruses associated with the diseases.

SAB-185 exhibited equivalent neutralization of the Munich, Alpha, Beta, Gamma variants and a variant isolated from an immunocompromised patient. 

It retained neutralization of the Delta variant AY.1 and multiple Omicron variants, with only modest losses of neutralization activity. 

Prophylactic SAB-185 treatment protected the hamsters from death and minimized signs of infection when challenged with the variant viruses tested. 

Phase 2a trial for SAB-176 met its primary endpoint of reducing the nasopharyngeal viral load in subjects challenged with H1N1 A/California/2009-like virus. 

SAB-176 also met secondary endpoints of reducing symptoms by Day 4 and shortened the timeframe of the ability to culture virus in vitro, suggesting reduced viral shedding, and was safe and well tolerated.

Biophytis Shares Gain After Detailed Data From Pivotal COVID-19 Treatment Study

 

  • Biophytis SA  has released the full results from its phase 2-3 COVA study evaluating Sarconeos (BIO101) for COVID-19-related respiratory failure.
  • The study's objective was to investigate the efficacy and safety of Sarconeos (BIO101), 350 mg BID, in hospitalized COVID-19 patients with hypoxemia, at risk of respiratory failure requiring high flow oxygen or mechanical ventilation, and death. 
  • On respiratory failure or early death, post-hoc analyses show a significant reduction with Sarconeos (BIO101) in the risk of early death or respiratory failure at day 28 by 45% in the Intent-To-Treat (ITT) population and by 53% in the Per Protocol (PP) population.
  • In the primary analysis, Sarconeos reduced by 39% the risk of respiratory failure or early death at 28 days compared to the placebo.
  • On mortality follow-up over 90 days, the risk of death was reduced with Sarconeos by 43% in the ITT population and 70% in the PP population. 
  • Sarconeos (BIO101) has a good safety profile, with a lower proportion of patients with adverse events compared to placebo (57% vs. 64%), in particular, a lower frequency of serious, primarily respiratory, adverse events (25% vs. 31%).
  • The company aims to file for conditional marketing authorization (Europe) and emergency use authorization (U.S., Brazil) as soon as possible in 2023. 

Provention: Prepping for Launch of Teplizumab Ahead of Nov 17th FDA User Fee Goal Date

 Provention Bio, Inc. (Nasdaq: PRVB), a biopharmaceutical company dedicated to intercepting and preventing immune-mediated disease, today reported financial results for the third quarter ended September 30, 2022 and provided a business update.

"Throughout the third quarter, we have continued to interact with the FDA in support of our resubmitted, breakthrough therapy designated, teplizumab BLA for the delay of clinical type 1 diabetes in at-risk individuals," stated Ashleigh Palmer, Chief Executive Officer & Co-Founder, Provention Bio. "As we approach our upcoming November 17th FDA action date, we are pleased to report that we have received both the FDA's proposed labelling and post-marketing requirements and commitments, and that these are generally consistent with our expectations. In parallel, we have been advancing our planning and preparations for the potential commercial launch of teplizumab and our recently announced co-promotion agreement, which allows us to leverage the expertise, capabilities, and commercial resources of Sanofi. Finally, we were able to strengthen our balance sheet by raising additional capital during the third quarter."

Third Quarter 2022 and Recent Corporate Highlights:

Entered into Agreement with Sanofi to Support Potential U.S. Launch of Teplizumab

On October 6, 2022, the Company announced that it entered a co-promotion agreement with Sanofi U.S. for the potential launch of Provention's lead investigational drug candidate, teplizumab. Teplizumab is currently under review by the U.S. Food and Drug Administration (FDA), for the delay of clinical type 1 diabetes (T1D) in at-risk individuals, with a user fee goal date of November 17, 2022.

The Company also granted Sanofi, in consideration of a non-refundable, one-time payment of $20.0 million, an exclusive, one-time right of first negotiation (ROFN) to obtain exclusive global rights to commercialize teplizumab for T1D in humans, subject to certain retained rights of the Company to engage in discussions with third parties with respect to certain transactions. Sanofi may exercise the ROFN until June 30, 2023, with an option to extend within 2023 under certain conditions. The Company received the $20.0 million payment in October from Sanofi.

Simultaneously with their entry into the co-promotion agreement, the Company and Sanofi entered into a Securities Purchase Agreement (the Purchase Agreement). Pursuant to the Purchase Agreement, if teplizumab is approved by the FDA, Sanofi has agreed to purchase $35.0 million of the Company's common stock at a premium over the daily volume-weighted average per share price for the five consecutive trading days prior to the closing date. The closing date will be at Provention's discretion and would occur no later than February 16, 2023.
