Safety results
Study limitations
Summary
The primary endpoint is a biochemical surrogate, not a direct measure of transplantation or survival. The topline release reports 149 randomized participants, whereas the later NDA-supporting report gives a phase 3 trial population of 148; these totals are not reconciled in the retrieved evidence. The combined-study registry enrollment of 196 is a different population. Pruritus improvement was not statistically significant at 12 months.

Summary
This study targets ALP above ULN but below 1.67 times ULN, rather than the higher ALP population in EPICS-III. Planned enrollment is 89 participants. The report contains a study design and eligibility record, but no treatment-effect estimates or observed safety results.

Aminotransferase increases after treatment discontinuation
Study limitations
Summary
This 37-participant trial lasted 16 weeks and tested 2 mg and 4 mg, not the later 1 mg magnesium regimen. Four participants discontinued treatment because of aminotransferase increases. The conference report describes one participant requiring immune suppression for suspected overlap syndrome, whereas the journal abstract summarizes recovery after discontinuation. Neither report establishes a long-term clinical-outcome benefit.

Health-related quality of life and patient-reported outcomes
No evidence found.
Safety results
No evidence found.
Study limitations
Summary
Only seven participants were enrolled, all female, and the study ended because of lack of enrollment. Its open-label, single-arm design cannot separate treatment effects from changes that would have occurred without saroglitazar. The 16-week biochemical assessment does not establish a transplantation or survival benefit.

Month 6 pruritus: least-squares mean difference against placebo
Safety results
Overall and serious adverse events
Study limitations
Summary
This is comparator evidence, not a randomized comparison against saroglitazar. The primary endpoint was biochemical response after 12 months, and the pruritus analysis concerned a subgroup with baseline scores of at least 4. The prescribing information does not establish improved survival or prevention of liver decompensation.

Adverse events more frequent with elafibranor than placebo
Study limitations
Summary
This comparator trial does not provide a head-to-head estimate against saroglitazar. Its primary endpoint was biochemical response at 52 weeks. The population was 96% female, and eligibility excluded decompensated cirrhosis, limiting extrapolation to that population.

Study design
Double-blind, placebo-controlled phase 3 design: duration
Eligibility criteria
Inadequate UDCA response criterion

Study limitations
Summary
This 100-participant comparator trial lasted 24 months and evaluated bezafibrate added to UDCA, not saroglitazar. Its complete biochemical-response definition differs from the EPICS-III composite, so the response percentages are not interchangeable across studies.

Safety results
Serious adverse events
Study limitations
Summary
This single-dose study enrolled healthy volunteers, not participants with PBC. Its 96 unique participants included eight men who participated in both parts, so the part-specific enrollments should not be added without accounting for overlap. It does not establish efficacy or repeated-dose safety in PBC.

Efficacy results
Hepatic impairment: single-dose study
| Population or parameter | Quoted finding |
|---|---|
| Mild and moderate hepatic impairment | “did not significantly affect the PK of saroglitazar” |
| Severe hepatic impairment: exposure | “increased 3-fold” |
| Severe hepatic impairment: clearance | “61% lower” |
| Severe hepatic impairment: authors’ qualification | “may require close monitoring or dose adjustments” |
Non-cirrhotic cholestatic liver disease: comparison with controls
Health-related quality of life and patient-reported outcomes
Not applicable.
Safety results
Single-dose tolerability
Study limitations
Summary
Single-dose pharmacokinetics do not establish repeated-dose safety or clinical efficacy. The 32 participants with hepatic impairment and 23 controls describe the published hepatic-impairment cohorts, not every cohort subsequently reported under this protocol. Severe impairment increased exposure, limiting extrapolation from mild or moderate impairment.

Health-related quality of life and patient-reported outcomes
No evidence found.
Safety results
Serious event in a participant receiving 2 mg
Study limitations
Summary
The study was open-label and lasted four weeks. It characterizes short-term pharmacokinetics rather than comparative clinical efficacy. Increased exposure in moderate hepatic impairment and the small cohort restrict extrapolation to longer treatment or broader cirrhotic populations.
