Intercept Announces First Patient Dosed in Phase 2 Study of OCA and Bezafibrate for the Treatment of Primary Biliary Cholangitis

MORRISTOWN, N.J., May 11, 2022 (GLOBE NEWSWIRE) -- Intercept Pharmaceuticals, Inc. (Nasdaq:ICPT), a biopharmaceutical company focused on the development and commercialization of novel therapeutics to treat progressive non-viral liver diseases, today announced the first patient has been dosed in a Phase 2 study evaluating a fixed-dose combination of obeticholic acid (OCA) and bezafibrate (BZF) for the treatment of patients with primary biliary cholangitis (PBC) who have not achieved an adequate biochemical response to ursodeoxycholic acid.

“Intercept is building on its legacy of innovation with the OCA-BZF fixed-dose combination, the first investigational therapy of its kind in PBC,” said M. Michelle Berrey, M.D., M.P.H., President of Research & Development and Chief Medical Officer of Intercept. “We believe OCA and BZF have synergistic mechanisms of action that can potentially provide additional benefits to people with PBC when used in combination. Additionally, both medicines have been shown to help lower the key biochemical measures that predict long-term outcomes in PBC. BZF has also been associated with improvements in pruritus, a potential benefit we are exploring in our Phase 2 program.”

The double-blind, randomized, active controlled, parallel group study will evaluate the reduction in alkaline phosphatase (ALP) over 12 weeks, followed by a long-term safety extension. The reduction in ALP has been accepted by regulators as part of a composite surrogate endpoint for investigational agents in PBC. Secondary endpoints include safety and tolerability, and other biochemical markers of disease progression: aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alanine aminotransferase (ALT) and bilirubin. The study is expected to recruit approximately 60 patients, primarily in the U.S., across four treatment arms:

• BZF 100 mg + OCA placebo tablet once daily (QD)
• BZF 400 mg + OCA placebo tablet QD
• BZF 100 mg + OCA 5 mg QD
• BZF 400 mg + OCA 5 mg QD

A second Phase 2 study, currently active in Europe, is evaluating different dosing regimens of the OCA-BZF combination. A large Phase 1 study is ongoing in the U.S., testing multiple different dose combinations in healthy adult subjects. Once complete, these three complementary studies will inform dose selection and study design for a Phase 3 trial.

About the OCA-Bezafibrate Fixed-Dose Combination

Intercept is studying combination therapy with OCA and bezafibrate for the treatment of individuals with PBC. OCA, an FXR agonist, is marketed as Ocaliva for the treatment of PBC in more than 40 countries (see below for full indication and Important Safety Information). Bezafibrate, a pan-peroxisome proliferator-activated receptor (pan-PPAR) agonist, has been studied for the treatment of PBC in Europe, but is not available in the United States. Initial proof-of-concept data indicate that the combination of OCA and bezafibrate carries the potential to help patients achieve reductions in ALP and bilirubin while improving pruritus. OCA-bezafibrate combination therapy is investigational; safety and efficacy have not been established and bezafibrate is not approved for the treatment of PBC in the United States or Europe.

About Ocaliva®(obeticholic acid)

OCALIVA, a farnesoid X receptor (FXR) agonist, is indicated for the treatment of adult patients with primary biliary cholangitis (PBC)

• without cirrhosis or
• with compensated cirrhosis who do not have evidence of portal hypertension, either in combination with ursodeoxycholic acid (UDCA) with an inadequate response to UDCA or as monotherapy in patients unable to tolerate UDCA.

This indication is approved under accelerated approval based on a reduction in alkaline phosphatase (ALP). An improvement in survival or disease-related symptoms has not been established. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.

IMPORTANT SAFETY INFORMATION

WARNING: HEPATIC DECOMPENSATION AND FAILURE IN PRIMARY BILIARY CHOLANGITIS PATIENTS WITH CIRRHOSIS

• Hepatic decompensation and failure, sometimes fatal or resulting in liver transplant, have been reported with OCALIVA treatment in primary biliary cholangitis (PBC) patients with either compensated or decompensated cirrhosis.
• OCALIVA is contraindicated in PBC patients with decompensated cirrhosis, a prior decompensation event, or with compensated cirrhosis who have evidence of portal hypertension.
• Permanently discontinue OCALIVA in patients who develop laboratory or clinical evidence of hepatic decompensation; have compensated cirrhosis and develop evidence of portal hypertension, or experience clinically significant hepatic adverse reactions while on treatment.

Contraindications

OCALIVA is contraindicated in patients with:

• decompensated cirrhosis (e.g., Child-Pugh Class B or C) or a prior decompensation event
• compensated cirrhosis who have evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia)
• complete biliary obstruction

Warnings and Precautions

Hepatic Decompensation and Failure in PBC Patients with Cirrhosis

Hepatic decompensation and failure, sometimes fatal or resulting in liver transplant, have been reported with OCALIVA treatment in PBC patients with cirrhosis, either compensated or decompensated. Among post-marketing cases reporting it, median time to hepatic decompensation (e.g., new onset ascites) was 4 months for patients with compensated cirrhosis; median time to a new decompensation event (e.g., hepatic encephalopathy) was 2.5 months for patients with decompensated cirrhosis.

Some of these cases occurred in patients with decompensated cirrhosis when they were treated with higher than the recommended dosage for that patient population; however, cases of hepatic decompensation and failure have continued to be reported in patients with decompensated cirrhosis even when they received the recommended dosage.

Hepatotoxicity was observed in the OCALIVA clinical trials. A dose-response relationship was observed for the occurrence of hepatic adverse reactions including jaundice, worsening ascites, and primary biliary cholangitis flare with dosages of OCALIVA of 10 mg once daily to 50 mg once daily (up to 5-times the highest recommended dosage), as early as one month after starting treatment with OCALIVA in two 3-month, placebo-controlled clinical trials in patients with primarily early stage PBC.

Routinely monitor patients for progression of PBC, including hepatic adverse reactions, with laboratory and clinical assessments to determine whether drug discontinuation is needed. Closely monitor patients with compensated cirrhosis, concomitant hepatic disease (e.g., autoimmune hepatitis, alcoholic liver disease), and/or with severe intercurrent illness for new evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia), or increases above the upper limit of normal in total bilirubin, direct bilirubin, or prothrombin time to determine whether drug discontinuation is needed. Permanently discontinue OCALIVA in patients who develop laboratory or clinical evidence of hepatic decompensation (e.g., ascites, jaundice, variceal bleeding, hepatic encephalopathy), have compensated cirrhosis and develop evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia), experience clinically significant hepatic adverse reactions, or develop complete biliary obstruction. If severe intercurrent illness occurs, interrupt treatment with OCALIVA and monitor the patient’s liver function. After resolution of the intercurrent illness, consider the potential risks and benefits of restarting OCALIVA treatment.

SeverePruritus

Severe pruritus was reported in 23% of patients in the OCALIVA 10 mg arm, 19% of patients in the OCALIVA titration arm, and 7% of patients in the placebo arm in a 12-month double-blind randomized controlled clinical trial of 216 patients. Severe pruritus was defined as intense or widespread itching, interfering with activities of daily living, or causing severe sleep disturbance, or intolerable discomfort, and typically requiring medical interventions. Consider clinical evaluation of patients with new onset or worsening severe pruritus. Management strategies include the addition of bile acid binding resins or antihistamines, OCALIVA dosage reduction, and/or temporary interruption of OCALIVA dosing.

Reduction in HDL-C

Patients with PBC generally exhibit hyperlipidemia characterized by a significant elevation in total cholesterol primarily due to increased levels of high-density lipoprotein-cholesterol (HDL-C). Dose-dependent reductions from baseline in mean HDL-C levels were observed at 2 weeks in OCALIVA-treated patients, 20% and 9% in the 10 mg and titration arms, respectively, compared to 2% in the placebo arm. Monitor patients for changes in serum lipid levels during treatment. For patients who do not respond to OCALIVA after 1 year at the highest recommended dosage that can be tolerated (maximum of 10 mg once daily), and who experience a reduction in HDL-C, weigh the potential risks against the benefits of continuing treatment.

Adverse Reactions

The most common adverse reactions (≥5%) are: pruritus, fatigue, abdominal pain and discomfort, rash, oropharyngeal pain, dizziness, constipation, arthralgia, thyroid function abnormality, and eczema.

Drug Interactions

• Bile Acid Binding Resins
  Bile acid binding resins such as cholestyramine, colestipol, or colesevelam adsorb and reduce bile acid absorption and may reduce the absorption, systemic exposure, and efficacy of OCALIVA. If taking a bile acid binding resin, take OCALIVA at least 4 hours before or 4 hours after taking the bile acid binding resin, or at as great an interval as possible.
• Warfarin
  The International Normalized Ratio (INR) decreased following coadministration of warfarin and OCALIVA. Monitor INR and adjust the dose of warfarin, as needed, to maintain the target INR range when co-administering OCALIVA and warfarin.

• CYP1A2 Substrates with Narrow Therapeutic Index
  Obeticholic acid may increase the exposure to concomitant drugs that are CYP1A2 substrates. Therapeutic monitoring of CYP1A2 substrates with a narrow therapeutic index (e.g., theophylline and tizanidine) is recommended when co-administered with OCALIVA.
• Inhibitors of Bile Salt Efflux Pump
  Avoid concomitant use of inhibitors of the bile salt efflux pump (BSEP) such as cyclosporine. Concomitant medications that inhibit canalicular membrane bile acid transporters such as the BSEP may exacerbate accumulation of conjugated bile salts including taurine conjugate of obeticholic acid in the liver and result in clinical symptoms. If concomitant use is deemed necessary, monitor serum transaminases and bilirubin.
