Is this trial a fit for you?

Likely a good fit

Adults aged 18 to 85 with severe renal impairment or ESRD (per CKD-EPI) and a BMI between 18.0 and 43.0 kg/m2.

Probably not a fit

Patients with recent organ transplant plans, significant laboratory abnormalities, or high tobacco use may not benefit from this trial.

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 trial to evaluate the safety profile and pharmacokinetics of the oral drug INCB123667 in adults with severe renal impairment or ESRD. Participants will be monitored for adverse events, laboratory changes, and drug exposure over a defined period. The study helps determine appropriate dosing considerations in this population. It is conducted at two sites in Florida and involves strict eligibility criteria focusing on renal function and overall health status.

Why it matters

Potential benefit: If successful, the results could inform dosing and safety for patients with severe kidney problems who may require this therapy.

How similar studies have gone: Previous early-phase studies of similar agents have demonstrated safety and pharmacokinetic insights in renal-impaired populations, supporting this approach's feasibility.

Exclusion Criteria:

* Participants who have a current, functioning organ transplant or are on the national transplant list and expected to receive a transplant within 3 months.
* Participants with laboratory values outside the accepted range for participants with severe renal impairment or ESRD at screening. Participants with out-of-range values will be assessed by the investigator or designee for eligibility.

* Participants who had a change in disease status within 30 days before screening, as documented by the participant's medical history, that is deemed clinically significant by the investigator.
* Participants who have a history of paracentesis within 3 months prior to check-in.
* Participants who required new medication or an increase in dose for renal disease within 3 months prior to check-in.
* Participants who have a history of unstable diabetes mellitus (as evidenced by hemoglobin A1c ≥ 10.0%). Medications for treatment of diabetes mellitus must be reviewed and approved by the investigator and medical monitor.
