Conatus Pharmaceuticals Inc. Announces Pre-Treatment Biomarker and Histology Data from the First 16 Patients Enrolled in its Phase 2B Clinical Trial

On June 25, 2015, Conatus Pharmaceuticals Inc. announced pre-treatment biomarker and histology data from the first 16 patients enrolled in the company’s Phase 2b clinical trial of its lead drug candidate, emricasan, in post-orthotopic liver transplant recipients. These patients have reestablished liver fibrosis or cirrhosis post-transplant as a result of recurrent hepatitis C virus infection and have successfully achieved a sustained viral response following HCV antiviral therapy. Among the first 16 patients enrolled, more than 85% achieved SVRs using recently approved oral HCV antiviral treatments. The excitement generated by these new treatments altered enrollment patterns during the early stage of the POLT-HCV-SVR trial, and their rapid market penetration is now expanding the trial-eligible population. The double-blind, placebo-controlled trial was initiated in May 2014 in patients with Ishak Fibrosis Scores of 2 to 4 (mid- to advanced-stage fibrosis). Consistent with the company’s initial registration focus on the development of a treatment for cirrhosis, the trial was expanded in early 2015 to include patients with Ishak 5 (early-stage cirrhosis) and is currently expanding to Ishak 6 (advanced-stage cirrhosis). Patients are being randomized 2:1 to receive either 25 mg of emricasan or placebo orally twice daily for 24 months and will be followed for another month post-treatment. The primary endpoint in this exploratory proof-of-concept trial is the change in the Ishak Fibrosis Score compared with placebo. The trial will also evaluate histological markers of inflammation, key serum biomarkers, and the safety and tolerability of emricasan in the target patient population. Enrollment of approximately 60 total planned patients is on track for release of final top-line results in the first half of 2018. The initial baseline data analysis included the first 16 patients (approximately 27% of the total planned enrollment) to meet all trial inclusion and exclusion requirements and enroll in the trial. Among those first 16 patients, 3 patients (19%) had baseline Ishak Fibrosis Scores of 2, 12 patients (75%) had baseline Ishak Fibrosis Scores of 3 or 4, and 1 patient (6%) had a baseline Ishak Fibrosis Score of 5 and none had an Ishak Fibrosis Score of 6. The proportion of cirrhosis patients enrolling in this trial is expected to increase during the remainder of the trial. Baseline serum levels of caspase-cleaved cytokeratin 18 (cCK18) and caspase 3/7 were elevated in these subjects. Both cCK18 and caspase 3/7 are biomarkers of apoptosis activity and mechanism-specific indicators for emricasan. The biomarker elevations also were generally consistent with histology, with the high levels of both cCK18 and caspase 3/7 observed in patients with Ishak 4, intermediate levels observed in patients with Ishak 3, and the lowest levels observed in patients with Ishak 2. Patients with Ishak 5 or 6 were not included in this analysis due to their recent inclusion and resulting low number at the cutoff date. The company concluded from the pre-treatment analyses of biomarkers and histology that: the underlying mechanisms of action relevant to emricasan were active and, POLT subjects who have fibrosis or cirrhosis due to HCV and achieved SVR are an appropriate patient population in which to evaluate potential treatment effects of emricasan.
