About SCY-635

SCY-635 is a cyclophilin inhibitor being developed as a novel, orally available agent for the treatment of viral diseases. In a Phase 2a study conducted in difficult to treat Hepatitis C (HCV) patients, SCY-635 modulated patients' immune response by making PEG-interferon refractory patients sensitive to anti-viral activity of PEG-interferon. Results of the study were presented at AASLD in Boston in 2012. SCY-635 has also shown in vitro activity against other viral diseases including Hepatitis B Virus (HBV).
