About this trial
This is an open-label, dose-escalation and dose-expansion study to determine the safety, tolerability, PK, pharmacodynamics, and preliminary efficacy of INCB123667 when administered as monotherapy and in combination with anticancer therapies in participants with selected advanced or metastatic solid tumors. This study will consist of 2 parts. In Part 1, INCB123667 will be administered as monotherapy and in Part 2, INCB123667 will be administered in combination with anticancer therapies of interest. Each part will comprise a dose escalation portion (Parts 1a and 2a, respectively) and a dose-expansion portion (Parts 1b and 2b, respectively).

Trial outcomes
Primary outcomes
Part 1A : Occurrence of Dose Limiting Toxicities (DLTs)
Toxicities occurring during the first treatment cycle, Part 1a, will define tolerability. DLTs will be assessed for severity by the investigator using CTCAE v5.0 criteria.
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
TEAE is any Adverse Event (AE) either reported for the first time or worsening of a pre-existing event after first dose of study drug.
Number of Participants with Dose Interruptions due to TEAE
Participants will receive dose reductions of INCB123667 according to lab guidelines. Treatment may be delayed for up to 2 weeks to allow for resolution of toxicity.
Number of Participants who Undergo Dose Reductions due to TEAE
Participants will receive dose reductions according to lab guidelines. Treatment may be delayed for up to 2 weeks to allow for resolution of toxicity.
Secondary outcomes
PK parameters: Cmax
Defines as the maximum (peak) plasma drug concentration
PK parameters: tmax
Defined as the time to reach maximum (peak) plasma concentration following drug administration
PK parameters: Ctau
Ctau is defined as concentration at the end of the dosing interval
PK Parameters: AUC
Defined as the area under the plasma concentration-time curve
