As part of Phages for Global Health's mission to help bring phage therapy to Africa and Asia, our founder, Dr. Tobi Nagel, serves on the advisory board of PhagePro, a company that is developing a phage product to control cholera outbreaks. Cholera currently infects an estimated 3 - 5 million people per year, and cholera bacterial strains worldwide are developing antibiotic resistance at an alarming rate. However, since this is a disease that almost exclusively occurs in developing countries, few companies are willing to develop new drugs to address it.

We are excited to report that PhagePro recently won $3 million in grants from the US National Institutes of Health to further its development of cholera phages! This will enable the company to work out product formulation and manufacturing issues and prepare for a clinical trial. The trial eventually will be conducted at the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), a renowned clinical research institute that treats a high number of cholera patients. In fact, the phages in PhagePro's product were originally isolated in collaboration with colleagues at icddr,b.

At a recent international conference called Phage Futures, Dr. Nagel and PhagePro’s CEO, Dr. Minmin Yen, co-led a virtual discussion group on “Phage Therapy for Preventing and Treating Diseases in Developing Countries”. Participants from many developing and developed countries attended, and there was much enthusiasm not only for the cholera phage project, but also for other potential phage applications in developing countries. There is still much work to do, but we are excited about eventually bringing cholera phages as well as other types of phages into the clinical setting!
