    Introduction: Patients with primary biliary cholangitis (PBC) without biochemical response to ursodeoxycholic acid (UDCA) are at increased risk of liver-related mortality. Saroglitazar is a novel peroxisome proliferator-activated receptor (PPAR) agonist with dual PPAR agonistic properties (α/γ). There is a strong mechanistic rationale for studying saroglitazar in PBC because PPARα is a molecular target of fibrates that showed improvements in liver tests in patients with PBC. Methods: In this 16-week, open-label, phase 3 study, 37 patients were screened across 3 clinical centers to enroll 7 patients. All patients received daily dose of saroglitazar 4 mg for 16 weeks in addition to their ongoing treatment with UDCA. The primary efficacy endpoint was the reduction in alkaline phosphatase (ALP) level at week 16 as compared to baseline. Results: Mean age of the study population was 51.1 ± 10.0 years, all patients were female of Mexican descent, and mean body mass index was 25.5± = 4.8 kg/m2. Six (85.7%) patients reported taking ursodiol at baseline and continued throughout the study with a mean daily dosage of 417 mg. Among these, the daily dosage of UDCA 500 mg in 4 and 250 mg in 2 subjects, respectively. The mean baseline ALP level was 230 ± 103 U/L. The primary efficacy endpoint, mean change (reduction) from baseline in ALP concentration at week 16 based on the modified intent-to-treat population was -94 ± 53 U/L (P = 0.003), corresponding to a reduction of 48 ± 23%. Treatment with saroglitazar 4 mg resulted in a rapid and sustained decrease of ALP levels at week 4 (-84 ± 47 U/L, P = 0.003). Six patients who completed the study achieved mean ALP reduction of at least 40% at week 4 and all subsequent visits. Discussion: Although the study was terminated because of lack of enrollment, saroglitazar daily for 16 weeks resulted in rapid and sustained improvements in ALP with an acceptable safety profile in patients with PBC.
