Specific anti-H5N1 polyclonal immunoglobulins developed by Fab’entech raise the prospect of a new approach to the treatment of H5N1 Avian Influenza in humans
LYON, France--( )--Fab’entech, a French biopharmaceutical company specialized in developing specific polyclonal immunoglobulins against emerging infectious diseases announces that the company is launching its first clinical trial in humans for its product against the H5N1 Avian Influenza virus. If promising results from animal testing are confirmed, these immunoglobulins may provide a new specific approach for the treatment of subjects infected by or exposed to the H5N1 virus.
“The phase 1 clinical trial represents an important milestone in providing a potential innovative solution to combat H5N1 virus infections in humans”This approach is based on passive immunotherapy which consists in injecting patients with specific antibodies (immunoglobulins) capable of recognizing, targeting and neutralizing the virus. Based on an already validated and well-established production process at industrial scale, Fab’entech is able to provide highly purified immunoglobulins to neutralize the virus.
"The phase 1 clinical trial represents an important milestone in providing a potential innovative solution to combat H5N1 virus infections in humans," said founder and CEO of Fab’entech, Dr. Bertrand Lépine, MD. "The clinical trial will take place in Singapore, located in the Asia-Pacific region where the risk of propagation of H5N1 virus is one of the highest in the world. The injection of specific anti-H5N1 polyclonal immunoglobulins is likely to provide immediate protection for people who have been infected with or exposed to the virus."
The good safety profile and the efficacy of this product have been extensively documented in animal studies conducted in collaboration with the INSERM Jean Mérieux BSL-4 Laboratory of Lyon (France). The clinical trial in Singapore will involve 16 healthy adult volunteers who will be monitored for 5 weeks. It will be a double blinded, placebo controlled study, performed in strict compliance with Good Clinical Practices (GCP).
About Avian Influenza H5N1
Avian influenza is an infectious disease caused by the A(H5N1) strain of the influenza virus, which occurs primarily in birds (particularly wild water birds, but sometimes also poultry). Historically, human infections with avian influenza viruses have been extremely rare but certain H5N1 strains can cause serious infections in humans with a mortality rate that can reach 60-80% in some regions, particularly in Asia.
According to World Health Organisation (WHO), 608 human cases have been reported since 2003, including 30 human cases in the first half of 2012. The scientific community estimates that an H5N1 influenza pandemic remains a real threat, particularly if the H5N1 virus were to mutate and become transmissible between humans.
