"Enanta has also discovered EDP-239, an NS5A inhibitor for HCV infection. EDP-239 has successfully completed phase 1 studies in 2015, including a proof-of-concept study, but its further development will depnd upon its potential utility as an additional component of an EDP-494 containing therapy, which will be determined after early clinical trials of EDP-494"
