ContraVir is a biopharmaceutical company focused on the discovery and development of targeted antiviral therapies with two candidates in mid-to-late stage clinical development. ContraVir’s lead clinical drug, FV-100, is an orally available nucleoside analogue prodrug that is being developed for the treatment of herpes zoster, or shingles, which is currently in Phase 3 clinical development. In addition to direct antiviral activity, FV-100 has demonstrated the potential to reduce the incidence of debilitating shingles-associated pain known as post-herpetic neuralgia (PHN) in a Phase 2 clinical study. ContraVir is also developing CMX157, a highly potent analog of the successful antiviral drug tenofovir, for the Hepatitis B virus. CMX157’s novel structure results in decreased circulating levels of tenofovir, lowering systemic exposure and thereby reducing the potential for renal and bone side effects.
