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.

The planned study evaluates clinical outcomes over 48 months in a population with cirrhosis. Estimated enrollment is 386 participants. The retrieved evidence does not yet establish an effect on clinical events, and its cirrhotic eligibility population differs from the biochemical-response populations of earlier trials.

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.

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.

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.

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.

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.

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.
