SAN JOSE, Calif., Dec. 14, 2020 /PRNewswire/ -- Anixa Biosciences, Inc. (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer and infectious diseases, today announced that it and partner OntoChem GmbH have verified that one of their recently discovered compounds is similar in potency to remdesivir, the only approved anti-viral drug against SARS-Cov-2. As previously announced, Anixa and OntoChem had identified multiple compounds that could disrupt the function of a viral enzyme called an endoribonuclease (also known as Non-Structural Protein-15, or NSP-15).
Remdesivir is a pro-drug whose metabolite interferes with a SARS-CoV-2 enzyme, RNA-Polymerase. Similarly, Anixa's lead compound interferes with the function of another SARS-Cov-2 enzyme, NSP-15, the noted endoribonuclease. NSP-15 is needed by the virus to process its RNA, it's genetic code. Interfering with this enzyme makes it impossible for the virus to replicate. The comparison of potency with remdesivir was conducted in a human cell line by measuring IC50 in an assay known as a plaque reduction assay. IC50 is a standard measure of the amount of drug needed to inhibit replication (production of plaques) of the virus by 50%.
"Through medicinal chemistry modifications we feel we can improve this compound's potency even more. In the next few months, we will be testing the in vivo potency of this compound in an animal study," stated Dr. Amit Kumar, President and CEO of Anixa. "While we are all excited about the development of Covid-19 vaccines, we still do not know how long immunity is conferred by vaccination, nor do we know what will happen should the virus's spike protein mutate, like the flu virus."
Dr. Kumar added, "Therapies such as remdesivir, monoclonal antibodies and dexamethasone are required to be administered by injection in a hospital setting. Our compound, should it reach the market, is expected to be taken as a pill by patients infected by SARS-CoV-2, to eliminate the disease before symptoms require hospitalization. At the current time, there are no Covid-19 medicines that can be taken in an outpatient setting. Accordingly, we feel there is a need for inexpensive, orally administrable medicines for this viral infection."
Dr. Lutz Weber, CEO of OntoChem, stated, "Our team includes Anixa Biosciences, my team at OntoChem, a team of organic synthetic chemists in Austria and a national laboratory in Italy with a biosafety level 3 (BSL-3) laboratory and capabilities for animal studies. We began this project with Anixa from scratch and are pleased that our collaboration has led to a very potent anti-viral compound. While we take our first compound into proof-of concept animal studies, we will continue synthesizing and testing additional promising compounds."
