Benznidazole is an oral anti-parasitic medication used in the treatment of Chagas disease, caused by a protozoan parasite Trypanosoma cruzi carried and transmitted by triatomine insects (aka “kissing bugs”). According to the Centers for Disease Control and Prevention (CDC), an estimated 300,000 people in the United States are infected with Chagas disease, which, if left untreated, can lead to serious and potentially life-threatening cardiovascular, gastro-intestinal and neurological complications. Benznidazole is the current preferred treatment for Chagas disease in other parts of the world but is not currently approved by the FDA in the U.S.

Meeting minutes received from the FDA’s Division of Anti-Infective Products confirmed key elements of the company’s overall plan for benznidazole, including:

“This guidance makes it clear that we are on the right track with our development of benznidazole for Chagas disease, and we expect we will progress expeditiously toward a submission,” said Cameron Durrant, MD, KaloBios chairman and CEO. “Our team continues to execute and we look forward to further collaborative engagement with FDA.”
