FDA authorizes Covid antibody treatment as preventive after exposure

“The unvaccinated or people with weak immune systems at high risk of severe disease can receive an injection if exposed to an infected person.

People at considerable risk of developing severe Covid-19, including millions of Americans with compromised immune systems, now have the option of receiving a preventive monoclonal antibody treatment if they have been or are at risk of being exposed to the coronavirus.

The Food and Drug Administration’s action on Friday brings hope to the estimated 3 percent of Americans who are immunocompromised, including those with autoimmune diseases, HIV patients, cancer patients and organ transplant recipients, who may still be vulnerable to Covid even after being fully vaccinated.

This is the first time an injectable coronavirus antibody treatment has been approved for use as a prevention of Covid after someone has been exposed to the virus.”

Tonix Pharmaceuticals and Massachusetts General Hospital (MGH) Enter into Research Collaboration on Tonix’s Third Generation anti-CD40-Ligand Monoclonal Antibody, TNX-1500, for the Treatment and Prevention of Kidney Transplant Rejection

“Transplantation experts led by Tatsuo Kawai, M.D., Ph.D., Surgical Director of the Living Donor Transplantation and Dialysis Access Program at MGH and Professor of Surgery at Harvard Medical School (HMS) will study TNX-1500 in kidney transplantation in a variety of models including non-human primates. The goal of the collaboration is to advance TNX-1500 as a potential first-in-class therapeutic to prevent and treat kidney transplant rejection.

Dr. Kawai said, “Anti-CD40-ligand therapy has a unique activity in controlling the immune response to organ transplants.2 There remains a significant need for new treatments to reduce the toxicity of current treatments by more selectively suppressing immune responses or inducing specific tolerance to the transplanted organ. Anti-CD40-ligand has shown promise not only to effectively suppress rejection but also to facilitate ‘transplant tolerance’ in multiple preclinical transplant models.6”
