Outcomes

Primary Outcomes

Part 1: Number of Participants With Dose-limiting Toxicities (DLTs)

Any adverse event that ws at least possibly related to study treatment and met protocol-specified criteria was classified as a DLT. For the purpose of dose finding, decisions on dose were based on DLTs observed during the first 21 days of treatment.

Time frame: up to 3 weeks

Part 1: Number of Participants With Any Treatment-emergent Adverse Event (TEAE)

An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it was considered drug related. An AE therefore could have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. A TEAE was defined as an AE that was either reported for the first time or the worsening of a pre-existing event after the first dose of either study drug until 104 days after the last dose of study treatment or the start of new anticancer therapy.

Time frame: up to approximately 1 year

Part 1: Number of Participants With TEAEs Leading to a Dosing Modification (Treatment Interruption, Dose Reduction, and Permanent Discontinuation of Either Study Drug)

An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it was considered drug related. An AE therefore could have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. A TEAE was defined as an AE that was either reported for the first time or the worsening of a pre-existing event after the first dose of either study drug until 104 days after the last dose of study treatment or the start of new anticancer therapy.

Time frame: up to approximately 1 year

Part 2: Objective Response

Objective response was defined as the percentage of participants with a best overall response (BOR) of complete response (CR) or partial response (PR) by investigator assessment per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (v1.1). CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 millimeters (mm). PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions.

Secondary Outcomes

Part 2: Number of Participants With Any TEAE

Time frame: up to 2 years

Part 2: Number of Participants With TEAEs Leading to a Dosing Modification (Treatment Interruption, Dose Reduction, and Permanent Discontinuation of Either Study Drug)

Time frame: up to 2 years

Part 1: Objective Response

Objective response was defined as the percentage of participants with a BOR of CR or PR by investigator assessment per RECIST v1.1. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 millimeters (mm). PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions.

Time frame: up to 335 days

Part 1: Disease Control

Disease control was defined as the percentage of participants with a BOR of CR, PR, or stable disease (SD) by investigator assessment per RECIST v1.1. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 mm. PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. PD: progression of a target or non-target lesion or presence of a new lesion. SD: no change in target lesions to qualify for CR, PR, or PD.

Time frame: up to 335 days

Part 1: Duration of Response (DOR)

DOR was defined as the time from the first CR or PR until disease progression by investigator assessment per RECIST v1.1 or death from any cause, whichever occurred earlier. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 mm. PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. PD: progression of a target or non-target lesion or presence of a new lesion.

Time frame: up to 335 days

Part 1: INCB099280 and Axitinib Plasma Concentrations

Blood samples were collected for the analysis of INCB099280 and axitinib concentrations. Per Protocol, PK samples for axitinib were only to be analyzed in case of a concern that axitinib was not as active as expected. Due to the early termination of the study before readout, these samples were not analyzed.

Time frame: Cycle 1 Day 1, Cycle 2 Day 1, Cycle 4 Day 1, and Cycle 8 Day 1: before INCB099280 and axitinib dose. Cycle 1 Day 1 and Cycle 2 Day 1: 1, 2, and 4 hours after INCB099280 dose. End-of-trial visit: axitinib sample
