Enanta\u2019s clinical programs are currently focused on respiratory syncytial virus (RSV) and its earlier-stage immunology pipeline aims to develop treatments for inflammatory diseases by targeting key drivers of the type 2 immune response, with KIT, STAT6 and MRGPRX2 inhibition.<\/p>\n<p>\nGlecaprevir, a protease inhibitor discovered by Enanta, is part of one of the leading treatment regimens for curing hepatitis C virus (HCV) infection and is sold by AbbVie in numerous countries under the tradenames MAVYRET\u00ae (U.S.) and MAVIRET\u00ae (ex-U.S.) (glecaprevir\/pibrentasvir). A portion of Enanta\u2019s royalties from HCV products developed under its collaboration with AbbVie contribute ongoing funding to Enanta\u2019s operations.
