SAN FRANCISCO--(BUSINESS WIRE)--Presidio Pharmaceuticals, Inc. today announced progress with its HCV antiviral drug discovery and development programs. A primary company objective is to advance multiple potent and safe inhibitors that target multiple HCV proteins and provide pan-genotypic coverage, as we believe such combination therapies will more adequately address the global medical need in the future. To that end, the company intends to bring 2 or 3 of its novel HCV NS5A inhibitors through early clinical development (Phase 1b/2a), with subsequent Phase 2-3 clinical evaluation of such NS5A candidates in suitable combination regimens with other HCV antivirals through corporate partnering or intercompany collaborations.
