ContraVir Pharmaceuticals Selected to Present Poster on TXL™ at the Upcoming AASLD Meeting® 2017

EDISON, N.J., Aug. 08, 2017 -- ContraVir Pharmaceuticals, Inc. (NASDAQ:CTRV), a biopharmaceutical company focused on the development and commercialization of targeted antiviral therapies, announced today an abstract for TXL™ has been selected by the Scientific Program Committee of the American Association for the Study of Liver Diseases (AASLD) for a poster presentation on October 21, 2017.

WHAT: Tenofovir exalidex (TXL™) is a highly potent prodrug of the antiviral tenofovir.  Tenofovir is the active component of both Vemlidy (tenofovir alafenamide) and Viread® (tenofovir disoproxil fumarate). TXL’s novel liver-targeting prodrug structure results in decreased systemic circulating levels of tenofovir, thereby reducing the potential for renal and bone side effects. ContraVir has completed a Phase 2a trial of TXL™, in which HBV-infected subjects were administered doses up to 100 mg for 28 days and is now working to optimize the formulation to further enhance drug delivery. To date, TXL™ has achieved clinical proof of concept for antiviral activity and displayed an excellent safety, tolerability, and pharmacokinetic profile. Based on the agent’s best-in-class potential, ContraVir believes TXL™ can become the cornerstone of a curative combination therapy for hepatitis B.

About ContraVir Pharmaceuticals

ContraVir is a biopharmaceutical company focused on the development and commercialization of targeted antiviral therapies with a specific focus on developing a potentially curative therapy for hepatitis B virus (HBV). The Company is developing two novel anti-HBV compounds with complementary mechanisms of action. TXL™ currently in Phase 2a, is designed to deliver high intrahepatic concentrations of TFV, while minimizing off-target effects caused by high levels of circulating TFV. CRV431, the other anti-HBV compound, is a next-generation cyclophilin inhibitor with a unique structure that increases its potency and selective index against HBV. ContraVir is also developing Valnivudine™, an orally available nucleoside analogue prodrug; Valnivudine™ is currently in Phase 3 for the treatment of herpes zoster. In addition to direct antiviral activity, Phase 2 data suggest that Valnivudine™ has the potential to reduce the incidence of debilitating shingles-associated pain known as post-herpetic neuralgia (PHN). For more information visit www.contravir.com.
