SAN DIEGO, May 04, 2017 (GLOBE NEWSWIRE) -- Conatus Pharmaceuticals Inc. (Nasdaq:CNAT) today announced that Novartis has exercised its option to an exclusive license for the global development and commercialization of emricasan, the company's first-in-class, orally-active pan-caspase inhibitor, under terms of the Option, Collaboration and License Agreement signed in December 2016. Subject to usual and customary conditions, including required anti-trust approvals, the license will become effective upon Conatus' receipt of a $7 million option exercise payment, expected in mid-2017. The option exercise by Novartis followed notification by Conatus of the initiation of the Phase 2b ENCORE-LF (for Liver Function) randomized, double-blind, placebo-controlled clinical trial evaluating emricasan in patients with decompensated liver cirrhosis caused by nonalcoholic steatohepatitis (NASH).
With the $50 million upfront payment received in December 2016, the $15 million received in exchange for a convertible promissory note issued to Novartis in February 2017, the anticipated $7 million option exercise payment, and Novartis sharing 50% of the costs of Conatus' four ongoing Phase 2b emricasan clinical trials after the license becomes effective, the company believes that current financial resources are sufficient to maintain operations and ongoing clinical development activities through the end of 2019. In addition, with the Novartis commitment to fund Phase 3 single agent emricasan development and all combination drug development activities, the company believes the resources are in place to complete emricasan development both as a single agent for NASH cirrhosis, and as a single agent or part of a combination drug therapy for NASH fibrosis.
Conatus is eligible to receive significant payments if certain clinical development, regulatory and commercial milestones are met, as well as tiered double digit royalties on emricasan single agent sales and tiered single to double digit royalties on sales of combination drug products containing emricasan. Conatus has the option to co-commercialize emricasan in the United States, including combination drug therapies, on a cost-sharing and revenue-sharing basis in lieu of U.S. royalties and with reduced ex-U.S. royalties.
"We are excited that Novartis has demonstrated its commitment to our collaboration with the timely exercise of its license option following the initiation of the ENCORE-LF clinical trial," said Conatus co-founder, President and Chief Executive Officer Steven J. Mento, Ph.D. "We believe this collaboration provides emricasan with its best opportunity to advance through the remaining development process toward making this novel treatment available to patients. We remain focused on the timely completion of our emricasan Phase 2b clinical development program, with expected data readouts beginning in the first half of 2018, and on rolling out independent pipeline development opportunities later in 2017 to build additional long-term value for our shareholders."
ENCORE-LF Clinical Trial
The ENCORE-LF clinical trial is expected to be conducted at approximately 90 clinical sites, and is designed to evaluate dosing, efficacy and safety of emricasan in approximately 210 patients with decompensated NASH cirrhosis. Patients will be randomized 1:1:1 to receive 5 mg of emricasan, 25 mg of emricasan, or placebo twice daily for at least 48 weeks. The primary endpoint is event-free survival for each treatment group compared with the placebo group. For the purposes of the trial, events are defined as all-cause mortality, new decompensation events, or a progression of ≥4 points in the Model for End-stage Liver Disease (MELD) score. Key secondary endpoints include safety and tolerability, MELD and Child-Pugh scores, liver transplantation rates, liver metabolic function using the BreathID® Methacetin Breath Test, and health-related quality of life.
"With the initiation of ENCORE-LF, we believe emricasan is the only treatment candidate being evaluated in clinical trials in patients with both compensated and decompensated NASH cirrhosis," added Dr. Mento, "reflecting emricasan's demonstrated ability to improve both portal hypertension and liver function. With additional clinical trials in patients with NASH fibrosis and in liver transplant recipients with residual fibrosis and cirrhosis after clearance of their hepatitis C virus infections, we are exploring emricasan's broad potential in multiple segments of chronic liver disease with significant unmet medical need, using clinically relevant endpoints in four defined patient populations, any or all of which we believe could define potential pathways to registration."
Conatus is conducting three ongoing EmricasaN, a Caspase inhibitOR, for Evaluation (ENCORE) clinical trials designed to evaluate emricasan treatment in various NASH patient populations:
The company is conducting a fourth ongoing clinical trial in hepatitis C virus (HCV) patients:
Results from the four ongoing emricasan clinical trials are expected to support the design of Phase 3 clinical efficacy and safety trials.
