Robert Hindes, MD, co-founded Trek Therapeutics, which is organized as a public benefit corporation that seeks ways of developing innovative yet affordable and accessible antiviral medications. As chief medical officer, Robert Hindes, MD, is engaged with his team in Phase 2a studies of TD-6450 plus faldaprevir.

Faldaprevir, a second generation protease inhibitor, was initially developed for use with ribavirin and pegylated interferon, and it is currently used in new regimens that are interferon-free. In phase 2b and 3 studies in patients with previously untreated genotype 1b hepatitis C virus (HCV), faldaprevir combined with pegylated interferon and ribavirin resulted in SVR rate of 82%.

A 2015 paper published in Liver International evaluated the Phase 2b SOUND-C2 interferon-free study involving a combination of faldaprevir, ribavirin, and deleobuvir. The combination resulted in overall SVR rate of 92%, and was well-tolerated among patients with HCV genotype-1a and 1b. Along with simeprevir, faldaprevir is considered one of the most effective second generation protease inhibitors.
