Phase 3
Completed
Conditions
Primary Biliary Cholangitis
Interventions
Registration Number
NCT03602560
Lead Sponsor
CymaBay Therapeutics, Inc.
Brief Summary

A 52-week, placebo-controlled, randomized, Phase 3 study to evaluate the safety and efficacy of seladelpar in subjects with primary biliary cholangitis (PBC) and an inadequate response to or intolerance to ursodeoxycholic acid (UDCA)

The participants might enter the ongoing open-label safety study (NCT03301506) following this double-blind study.

Detailed Description

Primary:

* To evaluate the safety and effect on cholestasis of two seladelpar regimens (5 mg/day titrated to 10 mg/day and 10 mg/day) over 52 weeks of treatment compared to placebo

Key Secondary:

* To evaluate the effect of seladelpar on normalization of alkaline phosphatase (AP) levels

* To evaluate the effect of seladelpar on pruritus

Male subjects who are sexually active with female partners of reproductive potential must use barrier contraception and their female partners must use a second effective birth control method during the study and for at least 90 days after the last dose

Exclusion Criteria

  7. Creatine kinase (CK) above 1.0 × ULN

  8. eGFR below 60 mL/min/1.73 m2 (calculated by MDRD formula)

  9. International normalized ratio (INR) above 1.0 × ULN

  10. Platelet count below 100 × 103/µL

  11. Presence of clinically significant hepatic decompensation, including:

    • History of liver transplantation, current placement on liver transplantation list, or current MELD score ≥ 15
    • Complications of portal hypertension, including known esophageal varices, history of variceal bleeds or related interventions (e.g., transjugular intrahepatic portosystemic shunt placement), relevant ascites, hepatic encephalopathy
    • Cirrhosis with complications, including history or presence of spontaneous bacterial peritonitis
  12. Other chronic liver diseases:

    • Current features of auto-immune hepatitis as determined by the investigator based on immunoserology, liver biochemistry and histology
    • Primary sclerosing cholangitis determined by presence of diagnostic cholangiographic findings
    • History or clinical evidence of alcoholic liver disease

    • Hepatitis C defined as presence of HCV RNA
  13. Known history of HIV

  14. Evidence of significant alcohol consumption

  15. Evidence of drug abuse

  16. Subjects with inadequate response to obeticholic acid (OCA) or intolerance to OCA: OCA must be discontinued 30 days prior to Screening

  17. Use of colchicine, methotrexate, azathioprine, or long-term systemic corticosteroids (> 2 weeks) within two months prior to Screening

  18. Use of fibrates within 30 days prior to Screening

  19. Use of simvastatin within 7 days prior to Screening

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Response to Composite Endpoint of ALP <1.67 × Upper Limit of Normal [ULN], ≥15% Reduction in ALP, and Total Bilirubin ≤ ULN) at Month 3Month 3

Percentage of Participants with Response to Composite Endpoint of ALP \<1.67 × Upper Limit of Normal \[ULN\], ≥15% reduction in ALP, and total bilirubin ≤ ULN) at Month 3. The mITT analysis set included all randomized subjects who received at least one study drug dose.

The primary endpoint was analyzed using Cochran-Mantel-Haenszel (CMH) test adjusted for both randomization stratification variables (ALP level: \<350 U/L and 2:350 U/L; pruritus NRS: \<4 and 2:4). The CMH tests were performed for the comparison of 10 mg versus placebo and 5 mg/10 mg versus placebo separately.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Pruritus NRS for Subjects With Baseline NRS ≥4 at Month 3Month 3

Pruritus Numerical Rating Scale (NRS) used to rate the intensity of the worst itching you experienced in the past 24 hours from no itching to worst possible itching by selecting a number from 0 to 10 on Itch Scale. Zero means no itching and 10 means worst imaginable itching. The analysis will be limited to those subjects in the mITT analysis set with a baseline NRS ≥ 4.

Percentage of Participants With Response Defined by Normalized Alkaline Phosphatase Levels at Month 3Month 3

The response was defined by normalized ALP levels (ALP ≤1.0 × ULN) at endpoint. The mITT analysis set included all randomized subjects who received at least one study drug dose.
