Atea Pharmaceuticals' hepatitis C treatment regimen, combining bemnifosbuvir and ruzasvir, showed 98% sustained virologic response in Phase 2 trial, with 99% success rate among non-cirrhotic patients. The company aims to simplify treatment duration and pill count in Phase 3, targeting a younger, less adherent patient population. Atea seeks to carve a niche in the hepatitis C market with a more convenient treatment option.
