ContraVir Pharmaceuticals Completes Renal Impairment Study with TXL™

February 6, 2018

EDISON, N.J., Feb. 06, 2018 (GLOBE NEWSWIRE) -- ContraVir Pharmaceuticals, Inc. (NASDAQ:CTRV), a biopharmaceutical company focused on the development and commercialization of targeted antiviral therapies, announced today the results of a Phase 1 study with TXL™ assessing the safety, pharmacokinetics and tolerability of TXL™ in patients with severe renal impairment.

The study of 16 subjects included 8 healthy subjects with normal kidney function and 8 subjects with severely impaired kidney function. Results from the study confirmed that TXL™ was safe and well tolerated in both patient groups.

Importantly, the data showed that the blood concentrations of tenofovir (TFV) in severely renally-impaired subjects receiving 50 mg of TXL™ were similar to the TFV exposure levels observed after dosing of Viread® 300 mg, the current standard of care. These findings indicate that dosing strength adjustments of TXL™ is not warranted in patients with compromised renal function.

“We are pleased with the results of this study, as the findings move us one step closer to successfully meeting the criteria for the registration filing of TXL™,” said James Sapirstein, Chief Executive Officer of ContraVir. “As expected, this study demonstrates that TXL™ continues to be well tolerated. Furthermore, the data from this study extend the validation from our previous findings in our Phase 2a study of the elimination pathway and safety of TXL™. We look forward to the continued development of TXL™ and we plan to present additional results at future scientific meetings.”

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™, designed to deliver high intrahepatic concentrations of TFV while minimizing off-target effects caused by high levels of circulating TFV, recently completed a Phase 2a trial. 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. In vitro and invivo studies have thus far demonstrated that CRV431 reduces HBV DNA and other viral proteins, including surface antigen (HBsAg). For more information visit www.contravir.com.
