Is this trial a fit for you?

Likely a good fit

Adults aged 18–80 with moderate or severe hepatic impairment (CP score) and no conflicting medical conditions that would affect safety or pharmacokinetic assessments.

Probably not a fit

People without hepatic impairment or those with conditions that disqualify participation may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 1 interventional study evaluating oral INCB123667 in adults with hepatic impairment. The main focus is to characterize safety and pharmacokinetics, including how the drug is absorbed, distributed, metabolized, and excreted in this population. Eligible participants are 18 to 80 years old with documented moderate or severe hepatic impairment and a BMI between 18.0 and 43.0 kg/m2. The study is conducted at several U.S. sites under Incyte Corporation in collaboration with local liver health centers.

Why it matters

Potential benefit: If successful, participants could contribute to understanding appropriate dosing and safety for people with liver impairment.

How similar studies have gone: Previous phase 1 studies of similar compounds provide benchmarks for safety and PK in hepatic impairment, supporting the rationale for this study.
