Polyclonal antibodies are a safe, reproducible, and rapidly scalable solution that is designed to meet public health challenges.
FREMONT, CA: Fabentech, a leading biopharmaceutical laboratory specializing in emergency immunotherapy, launches a new program to develop an immunotherapy treatment against COVID-19. This treatment will be used for severely ill patients requiring respiratory assistance. Its human clinical trials should start in early 2021.

This development and production platform, based on a polyclonal immunotherapy technology to meet public health pain points, allows targeted recognition of a virus or toxin and its specific neutralization. The company has already demonstrated the effectiveness and safety of this approach while designing its own products. This new COVID-19 program stems from the R&D and industrial platform created by Fabentech over the last decade, which draws on technology proven in the treatment of infectious diseases.
Fabentech has raised 8.5 million from Definvest fund of the Ministry of the Armed Forces has helped the company move forward with a new industrial site that meets the needs of both the EMA (European Medicines Agency) and the FDA (Food and Drug Administration). Located near Lyon, this new unit will ensure the production of immunotherapy treatments against COVID-19 in France and will quickly ramp up to mount its production capacities and offer treatments to cover other markets.
The polyclonal antibodies neutralize the virus and retards its progression in the organism, giving the patients immune system time to produce its own antibodies. Furthermore, these have a synergistic effect with other existing therapies, which Fabentech was able to demonstrate in animals with H5N1 influenza by co-administering its anti-H5N1 product with oseltamivir. The study also showed a reduction in the nasal viral load, which is directly related to the level of contagiousness of the virus.
The process used by Fabentech makes it possible to keep only the active part of the fragments and removes the Fc fragments from the antibodies. This prevents an excessive immune response by the patient, which could lead to a cytokine storm. Based on a strategy similar to convalescent plasma therapy, this approach is a standardized, safer, more reproducible, and easily scalable solution.
