ContraVir to Showcase CMX157 Data in Poster at the 3rd ANRS HBV Cure Workshop

EDISON, N.J., May 25, 2016 /PRNewswire/ -- ContraVir Pharmaceuticals, Inc. (NASDAQ:CTRV), a biopharmaceutical company focused on the development and commercialization of targeted antiviral therapies, announced today that it will showcase key CMX157 data in a poster at the 3rd ANRS HBV Cure Workshop to be held Tuesday, May 31, 2016 at the UIC-Paris in Paris, France.

John Sullivan-Bólyai, MD, MPH, Chief Medical Officer of ContraVir, will be available to answer questions and discuss the positive data displayed in the poster showing enhanced safety and potency of CMX157, which is currently undergoing Phase 1/2a clinical studies.

CMX157 is a novel, liver-targeted, lipid conjugate prodrug of tenofovir (TFV) designed to utilize natural lipid uptake pathways to achieve high hepatocellular levels of the active antiviral. Greater than 97-fold potency vs. TFV, high plasma stability and high first-pass liver extraction are expected to result in low clinical doses and less circulating TFV resulting in decreased TFV toxicities, particularly to bone and kidneys, compared to the currently licensed TFV prodrug. These positive attributes of CMX157 underline its potential for anchoring single pill antiviral combinations aimed at achieving a cure for HBV infections.

Event: 3rd ANRS HBV Cure Workshop
Title: Preclinical Characterization of a Novel Tenofovir Prodrug, CMX157, for the Treatment of Hepatitis B
Date: May 31, 2016
Time: Lunch
Location: UIC-Paris, Paris, France

About ContraVir Pharmaceuticals
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.
