    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.

    Saroglitazar, a PPAR-α/γ Agonist, for Treatment of Nonalcoholic Fatty Liver Disease: A Randomized Controlled Double-Blind Phase 2 Trial
    (Wiley, 2021-10) Gawrieh, Samer; Noureddin, Mazen; Loo, Nicole; Mohseni, Rizwana; Awasty, Vivek; Cusi, Kenneth; Kowdley, Kris V.; Lai, Michelle; Schiff, Eugene; Parmar, Deven; Patel, Pankaj; Chalasani, Naga; Medicine, School of Medicine
    Background and Aims Non-alcoholic fatty liver disease (NAFLD) is characterized by insulin resistance and dysregulated lipid and glucose metabolism. Saroglitazar, a novel dual peroxisome proliferator activated receptor-α/γ agonist, improves insulin sensitivity, and lipid and glycemic parameters. Saroglitazar improved nonalcoholic steatohepatitis (NASH) histology in animal studies. In this randomized controlled clinical trial, we evaluated the efficacy and safety of saroglitazar in patients with NAFLD/NASH. Approach & Results A total of 106 patients with NAFLD/NASH with ALT ≥50 U/L at baseline and body mass index ≥25 kg/m2 were randomized in a 1:1:1:1 ratio to receive placebo or saroglitazar 1 mg, 2 mg, or 4 mg for 16 weeks. The primary efficacy endpoint was percentage change from baseline in ALT levels at Week 16. Liver fat content (LFC) was assessed by magnetic resonance imaging-proton density fat fraction. The least squares (LS) mean (SE) percent change from baseline in ALT at Week 16 was -25.5% (5.8), -27.7% (5.9) and -45.8% (5.7) with saroglitazar 1 mg, 2 mg, and 4 mg, respectively versus 3.4% (5.6) in placebo (p<0.001 for all). Compared to placebo, saroglitazar 4 mg improved LFC [4.1%, (5.9) versus -19.7% (5.6)], adiponectin [-0.3 ug/mL (0.3) versus 1.3 ug/mL (0.3)], homeostatic model assessment-insulin resistance [-1.3 (1.8) versus -6.3 (1.7)], and triglycerides [-5.3 mg/dL (10.7) versus -68.7 mg/dL (10.3)] (p<0.05 for all). Saroglitazar 4 mg also improved lipoprotein particle composition and size and reduced lipotoxic lipid species. Saroglitazar was well-tolerated. A mean weight gain of 1.5kg was observed with saroglitazar 4 mg versus 0.3 kg with placebo (p>0.05). Conclusions Saroglitazar 4 mg significantly improved ALT, LFC, insulin resistance and atherogenic dyslipidemia in participants with NAFLD/NASH.
