Non-alcoholic fatty liver disease (NAFLD) is accumulation of fat in the liver, which is not due to alcohol. When inflammation is present, it becomes non-alcoholic steatohepatitis (NASH), which can progress to cirrhosis and hepatocellular carcinoma. In Europe, prevalence of NAFLD is estimated at 20-30% in the general population and 2.6-10% in the paediatric population. Prevalence of NASH is approximately 5%. Fatty liver develops in up to 94% of obese individuals [3].

Trial or other data

Dec 19Interim analysis from PIII REGENERATE study (NCT02548351) published in The Lancet. Oeticholic acid 25 mg significantly improved fibrosis and key components of NASH disease activity. Fibrosis improvement was achieved in only 12% in placebo group vs. 23% in obeticholic acid group (p=0.0002) [19].
Apr 19Intercept is using post-hoc analysis to demonstrate benefit from obetacholic acid in non-alcoholic steatohepatitis patients. A dose of 25mg achieve a 2-stage or greater liver fibrosis improvement in 13.3% of patients, compared to 4.5% achieved by placebo [17].
Feb 19Intercept has reported that its PIII trial REGENERATE has published that it has met its primary endpoint of improving liver fibrosiswithout any worsening of NASH following 18 months of treatment. The study included 931 patients with NASH. It is reported that the highest dose of obeticholic acid improved liver fibrosis with no worsening of NASH at 23.1% compared to a rate of 11.9% for placebo patients. The secondary efficacy endpoint of NASH resolution with no worsening of liver fibrosis showed a numerical change in favour of obeticholic acid, but was not statistically significant. Serious ADEs were 11% for placebo, 11% for obeticholic acid 10mg and 14% for obeticholic acid 25mg. Two placebo arm patients died, and one obeticholic acid 25mg patient died (none were considered treatment related). Severe pruritus occurred in 5% of obeticholic acid 25mg patients, and hepatobiliary events occurred in 3% of these patients. The company plans to file for approval in the US and in Europe by the end of 2019 [16].
Feb 17Following discussion with the FDA and EMA, the primary endpoint for the REGENERATE trial has been amended to proportion of patients achieving improvement in fibrosis OR resolution in NASH compared to placebo - previously, the primary endpoint required achieving both outcomes and the change will increase the likelihood of trial success [12].
Aug 16Phase 3 REGENERATE trial enrollment completion for interim analysis expected in 1Q 2017 [11]
Nov 15REGENERATE trial also recruiting from EU and Australasia [10].
Oct 15PIII REGENERATE (NCT02548351) study is currently recruiting 2000 pts from sites in the US [9].
Oct 15Intercept announce that in a trial testing three doses of obeticholic acid against placebo in 200 patients, obeticholic acid failed to meet the primary outcome of at least a 2-point improvement in NASH symptoms, with only the highest doses, 20 mg and 40 mg achieving significance. The drug also failed to reach statistical significance on secondary endpoints including liver fat, inflammation, ballooning and resolution of NASH symptoms. Intercept´s share price fell about 14% on concerns that OCAmay struggle to replicate its earlier PII success as its 2,000-patient PIII trial gets underway. In Sep 15, Intercept began enrolment in a global study testing 10 mg and 25 mg of OCA versus placebo with primary endpoints of improving NASH symptoms, reducing liver scarring, and preventing death and end-stage liver disease. Final data won´t be ready until 2021, but an interim analysis will evaluate how well OCA is doing at resolving NASH and reducing scars in about 1,400 patients. Intercept plans to submit those results to the FDA for early approval [8].
Mar 15PIII FLINT study published in The Lancet. Obeticholic acid improved histological features of non-alcoholic steatohepatitis vs. placebo (45% in the obeticholic acid group vs. 21% in the placebo group (RR 1.9, 95% CI 1.3 to 2.8; p=0.0002) at 72 weeks [5].
Aug 14In a PIIb 283-patient study, obeticholic acid met its primary endpoint of improving fatty-liver disease symptoms without worsening scarring, with 46% of those in the treatment arm showing meaningful improvement vs. 21% on placebo. Obeticholic acid also met its secondary endpoints of broadly reducing disease scores and significantly improving liver scarring, with 35% of OCA patients reporting a reduction in fibrosis vs. 19% on placebo. Intercept planning to start enrollment in the PIII study in 1H 2015 [2].
Mar 11US PII/III FLINT trial (NCT01265498) of obeticholic acid, 25 mg/day in 280 patients with biopsy-proven non-alcoholic steatohepatitis patients has started. The primary endpoint is hepatic histological improvement in non-alcoholic fatty liver disease (NAFLD) activity score at 72 weeks. The trial is being conducted by the National Institute of Diabetes and Digestive and Kidney [1]
