U.S. FDA Approves IND for Bacteriophage Treatment of Patients with Resistant Infections of the Urinary Tract

Germantown, MD, USA (April 03, 2020) – Amarex Clinical Research, LLC announces that the U.S. Food and Drug Administration approved an IND application prepared and submitted by Amarex for their client Adaptive Phage Therapeutics, Inc. (APT). This allows APT to proceed with their Phase I/II study of a personalized bacteriophage therapeutic for the treatment of patients with multi-drug resistant (MDR) pathogenic bacteria and other complicated infections. This study helps APT expand their growing library of hundreds of bacteriophage (PhageBankTM) which kill the six highest priority MDR pathogenic bacteria.

Dr. Kazem Kazempour, President & CEO of Amarex stated, “This was a very challenging IND because bacteriophage is such a unique medical product. Many different phage will be treated as a single product, and maintaining the Drug Master File is complex as APT will be continually adding new phage. Another challenge was writing the clinical study protocol, with which Amarex assisted. It is a platform protocol with many potential cohorts structured in a decision tree format.”

“One of the difficult lessons we are all learning from the COVID-19 pandemic is that pharmaceuticals have to be able to rapidly adapt to new threats,” said Greg Merril, CEO of APT. “Our novel PhageBankTM approach allows for a rapid and adaptive approach to dealing with infectious disease. It’s the only way to combat these diseases and has required a new regulatory approach that Amarex has successfully helped us navigate.”

Amarex also prepared and submitted APT’s Type II Master File for Drug Product, and assisted APT with an Expanded Access use IND for several patients that had MDR infections. Amarex hopes to continue support of APT as they increase their phage bank and submit additional INDs for new therapeutic indications.
