BiondVax reports successful results in preclinical in vivo study of its innovative inhaled COVID-19 NanoAb therapy


BiondVax Pharmaceuticals Ltd.

  • Hamsters infected with SARS-COV-2 and subsequently treated with inhaled anti-COVID-19 NanoAbs showed significantly less severe disease and faster recovery compared to infected hamsters treated with inhaled placebo

  • BiondVax’s nanoantibodies (NanoAbs) are formulated as a convenient, self-administered, home inhaled COVID-19 therapy

  • First clinical phase 1/2a human trial planned for 2023

  • The COVID-19 therapy is BiondVax’s first in a new pipeline of innovative alpaca-derived NanoAb therapies that address diseases with high under-medical needs and attractive commercial opportunities such as psoriasis and asthma

Jerusalem, Nov. 29, 2022 (GLOBE NEWSWIRE) — via InvestorWire – BiondVax Pharmaceuticals Ltd. (Nasdaq: BVXV) (“BiondVax”), a biotechnology company focused on developing, manufacturing and commercializing innovative immunotherapeutic products primarily for the treatment of infectious and autoimmune diseases, announced today statistically significant (p<0.001) efficacy results in a preclinical in vivo proof-of-concept study of its innovative COVID-19 therapy with inhaled nanoantibodies (NanoAb).

Study design: Using an industry-standard animal model for COVID-19 therapies and vaccines, the study compared weight loss in two groups of hamsters after infection with SARS-COV-2. The first (experimental) group was treated with BiondVax’s anti-COVID-19 NanoAb administered via inhalation starting one day after infection, while the second (control) group was treated similarly, but with saline that served as placebo. The study was conducted by two world-renowned institutions: the Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM) and the University of Veterinary Medicine Hanover (TiHo), Germany.

Results: Compared to their weight immediately prior to infection, the weight of the control group decreased by an average of 12.01%, while the weight of the experimental group, which received BiondVax’s NanoAb via inhalation, only decreased by an average of 3.80%, a highly statistical significant result (p< 0.001).

The successful outcome was further supported by eight other parameters monitored, including heart rate and social behavior, which indicated that the group treated with inhaled NanoAbs experienced a milder and shorter illness.

NanoAb as mAb biobetter: As part of a strategic research collaboration with the Max Planck Institute for Multidisciplinary Sciences (MPG) and Göttingen University Medical Center (UMG), BiondVax is developing a pipeline of innovative alpaca-derived nanoantibody (NanoAb) therapies to address diseases with large underserved medical needs and attractive commercial opportunities, such as COVID-19, asthma, psoriasis, psoriatic arthritis and macular degeneration. While these diseases are currently treated with conventional monoclonal antibodies (mAbs), which generate billions of dollars in annual commercial sales, NanoAbs have the potential to capture significant market share as biobetters. In particular, NanoAbs show strong potential for superior patient convenience, safety and clinical outcomes, at a lower cost. For example, as demonstrated by this preclinical study, BiondVax’s NanoAb is efficacious when administered via inhalation rather than injection, as with currently available COVID-19 monoclonal antibody therapies.

WWe are pleased that the study results confirm the inhalation concept of our exclusively licensed NanoAb as a therapy for COVID-19 disease.” said BiondVax’s Chief Science Officer (CSO), dr. Tamar Ben-Yedididia PhD. “Following these promising results, we plan to continue the study early next year by testing additional dose levels of the inhaled NanoAb therapy and as a prophylactic (preventive) treatment. The results of the trial will inform the design of the first human clinical trial of the inhaled NanoAb COVID-19 therapy, which is scheduled to open in late 2023.

Ben-Yedidia concluded: “On behalf of the BiondVax team, I would like to thank the Fraunhofer ITEM and TiHo teams for their professionalism in conducting this ongoing study, as well as our research partners Professor Dr. Dirk Görlich from the Max Planck Institute for Multidisciplinary Sciences (MPG) and Professor Dr. Matthias Dobbelstein from Göttingen University Medical Center and their teams for the continued collaboration.

Mr Amir ReichmanCEO of BiondVax, added: “Recent articles have highlighted the limitations of existing therapies, especially Paxlovid (Pfizer) in high-risk populations, the absence of monoclonal antibodies highly effective against Omicron, and the need for new improved treatments to prevent serious disease. In addition, the use of COVID-19 vaccinations and boosters is declining. We believe that our NanoAb inhaled medicinal product can address this unmet need with a patient-friendly route of administration directly to the original source of infection.”

Next steps: This preclinical study will continue in January 2023 with additional arms testing lower therapeutic doses and a prophylactic dose of the inhaled COVID-19 NanoAb. The amount of live SARS-COV-2 virus in the lungs after treatment will also be assessed in each of the study groups. The study will also evaluate safety parameters. The results of the dosing study will guide the design of future clinical trials of BiondVax’s anti-COVID-19 inhaled NanoAb. In 2023, BiondVax will conduct a preclinical toxicity study as required by regulatory authorities for human clinical trial approval. The company will also scale up its manufacturing processes to produce the NanoAbs at its GMP manufacturing site in Jerusalem for the first-in-human Phase 1/2a clinical trial in patients, scheduled for Q4 2023.
