ContraVir to Highlight New Data at EASL The International Liver Congress™ 2017 in Amsterdam, The Netherlands

April 11, 2017
New data to highlight TXL™ and CRV431 in Hepatitis B Virus (HBV)

MEDIA ADVISORY, April 11, 2017 (GLOBE NEWSWIRE) --

WHAT: Tenofovir Exalidex (TXL™) is ContraVir’s lead drug for Hepatitis B in phase 2 clinical studies. TXL™ is a novel lipid acyclic nucleoside phosphonate that delivers high intracellular concentrations of the active antiviral agent of tenofovir, marketed by Gilead as Viread®. TXL™’s novel structure results in decreased circulating levels of tenofovir, lowering systemic exposure and thereby reducing the potential for renal side effects. TXL™ has completed a Phase 1 clinical trial in healthy volunteers, demonstrating a favorable safety, tolerability, and drug distribution profile.

Oral Presentation: Pharmacokinetics, Safety and Antiviral Activity of TXL™, a Novel Prodrug of Tenofovir, Administered as Ascending Multiple Doses to Healthy Volunteers and HBV-Infected Subjects

  • Selected to be included in the best of viral hepatitis at ILC2017 debrief recording, where Professor Fabien Zoulim and Professor Heiner Wedemeyer will provide overviews on the latest in viral hepatitis research and patient management
  • Date/Time:Thursday, April 20, 2017; 16:15-16:30 Central European Time (10:15-10:30am ET)
  • Session: Parallel session, Hepatitis B and D: Emerging Treatment Options
  • Location: RAI Amsterdam, Europaplein 22, Amsterdam, The Netherlands Entrance K
  • Abstract #: 1639

WHAT: CRV431 is an anti-HBV drug candidate whose principal action is inhibition of cellular cyclophilins. Cyclophilins are peptidyl-prolyl isomerases that broadly regulate protein structure and function, and they are recruited into the life cycles of several viruses, including Hepatitis B Virus.

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. One compound, TXL™ (formerly CMX157), is a highly potent analog of the successful antiviral drug Viread® (tenofovir disoproxil fumerate), and is currently in Phase 2a of development. TXL™ has demonstrated the potential for low, once-daily dosing and decreased systemic exposure compared to tenofovir, thereby potentially reducing renal and bone side effects. 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.
