Tobira Therapeutics Announces Data Presentations Highlighting Cenicriviroc at HEP DART 2015

Print 08 December 2015

SOUTH SAN FRANCISCO, Calif., Dec. 8, 2015 /PRNewswire/ -- Tobira Therapeutics, Inc. (NASDAQ: TBRA), a biopharmaceutical company developing novel treatments for non-alcoholic steatohepatitis (NASH) and other serious immuno-inflammatory and fibrotic diseases, today announced that data relating to cenicriviroc will be presented at HEP DART 2015 in Wailea, HI.

Tobira and its key collaborators presented two abstracts and a sponsor presentation on cenicriviroc (CVC), the company's lead CCR2/5 antagonist; CENTAUR, the company's Phase 2b study evaluating CVC in NASH; and enhanced liver fibrosis (ELF) index data from the company's completed HIV Phase 2b study.

"The clinical data presented at HEP DART continues to expand our understanding of how CVC may play an important role for the treatment of NASH with liver fibrosis," said Eric Lefebvre, M.D., chief medical officer at Tobira. "We are presenting for the first time baseline characteristics from the CENTAUR study, which was fully enrolled earlier this year with subjects with NASH and liver fibrosis who are therefore at high risk of progression to cirrhosis. Thus, the study population of CENTAUR is well aligned with the growing unmet need since this population is most likely to require and benefit from treatment. Additionally, this careful patient selection is expected to reduce the likelihood of spontaneous disease improvement and allow for detection of a potentially greater difference between CVC treatment and placebo."

About Cenicriviroc (CVC) and Non-alcoholic Steatohepatitis (NASH)
CVC is an oral, once-daily, potent immunomodulator that blocks two chemokine receptors, CCR2 and CCR5, which are intricately involved in the inflammatory and fibrogenic pathways in NASH that cause liver damage and often lead to cirrhosis, liver cancer or liver failure. Tobira believes this novel approach will establish CVC as both a single-agent and as a cornerstone treatment in multi-therapy regimens for NASH, for which there is currently no approved drug.

CVC is currently being evaluated in Tobira's fully enrolled global Phase 2b CENTAUR study (identifier NCT02217475) and the company expects to announce the study's primary endpoint in the third quarter of 2016. CENTAUR is comparing CVC to placebo in 289 patients with NASH and liver fibrosis. CVC has been granted Fast Track status in patients with NASH and liver fibrosis, the patient population at highest risk of progression to cirrhosis. The CENTAUR study includes surrogate endpoints identified as suitable for registrational studies in findings of an FDA-AASLD workshop reported in Hepatology. To date, approximately 600 subjects have been dosed in completed studies with CVC, including 115 HIV infected subjects on treatment for up to 48 weeks.

NASH is an emerging health crisis impacting 3% to 5% of the U.S. population and 2% to 4% globally. It is the fastest growing cause of liver cancer and liver transplant in the U.S. due to the rise in obesity. Additionally, this population is estimated to be three to five times larger than the size of the population with hepatitis C in the U.S.
