Key information

About this study

This study is an open-label Phase 1 evaluation of INCB001158 as a single agent and in combination with immune checkpoint therapy in patients with advanced/metastatic solid tumors.

Single Agent INCB001158:

Patients with advanced/metastatic solid tumors will be enrolled into escalating monotherapy dose cohorts to determine the Recommended Phase 2 Dose (RP2D) of INCB001158. Additional patients with NSCLC, Colorectal Cancer (CRC), and other tumors including SCCHN, RCC, Gastric, Bladder and Melanoma will be enrolled at the single agent RP2D.

Combination Treatment:

Patients with advanced/metastatic NSCLC, Melanoma, Urothelial, Microsatellite Instability (MSI)/ Microsatellite Stable (MSS) CRC, Gastric, SCCHN and Mesothelioma will be enrolled into separate cohorts of combination therapy (INCB001158 and Pembrolizumab) to determine the RP2D.

In the dose expansion phase, additional patients with NSCLC, Melanoma, Urothelial, MSI/MSS CRC, Gastric, SCCHN and Mesothelioma will be treated with the combination of INCB001158 and Pembrolizumab at the RP2D.

All patients will be assessed for safety, pharmacokinetics, biomarkers and tumor response.

Primary outcomes

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

    Time frame: up to study completion (up to approximately 3.5 years)

    An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. Abnormal laboratory values or test results occurring after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study treatment(s). A TEAE was defined as any adverse event that started or worsened after the first dose of study drug.

Secondary outcomes

  1. Recommended Phase 2 Dose (RP2D) of INCB001158

    Time frame: 12 weeks

    The RP2D was determined by a traditional 3+3 dose-escalation design of single-agent INCB001158 in participants with advanced/metastatic solid tumors at doses of 50, 75, 100, or 150 mg.

  2. RP2D of INCB001158 in Combination With Pembrolizumab

    Time frame: 12 weeks

    INCB001158 was dosed orally BID.

  3. Objective Response Rate (ORR)

    Time frame: Until disease progression/study discontinuation (up to approximately 5 years)

    ORR was defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (v1.1) as the percentage of participants with a confirmed best overall response of complete response (CR) or partial response (PR) at any post-Baseline visits prior to first disease progression and alternative cancer therapy use. 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. Pleural mesothelioma was evaluated using modified RECIST criteria. Confidence intervals were calculated based on the exact method for binomial distributions (Clopper Pearson). Two participants evaluable for PFS were not evaluable for response.

  4. Percentage of Participants With the Indicated Best Overall Response (BOR)

    Time frame: Until disease progression/study discontinuation (up to approximately 5 years)

    BOR was evaluated 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. Stable disease (SD): no change in target lesions to qualify for CR, PR, or progressive disease (PD). PD: progression of a target or non-target lesion or presence of a new lesion. Missing: participant had a missing BOR because there were no post-Baseline tumor assessments. Pleural mesothelioma was evaluated using modified RECIST criteria.

  5. Duration of Response (DOR)

    Time frame: Until disease progression/study discontinuation (up to approximately 5 years)

    DOR was defined as the number of months from the date of the first documentation of an objective response (CR or PR per RECIST v1.1) to the date of the first documentation of disease progression or death, whichever occurred first. 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. Pleural mesothelioma will be evaluated using modified RECIST criteria. Kaplan-Meier (KM) product-limit estimates with a log-log transformation were used for 95% confidence interval calculation.

  6. Progression-free Survival (PFS)

    Time frame: Until disease progression/study discontinuation (up to approximately 5 years)

    PFS was defined as the length of time between the date of the first dose and the earlier of death or progressive disease as assessed by RECIST v1.1. Pleural mesothelioma was evaluated using modified RECIST criteria. Participants enrolled in Part 1c had renal impairment. These participants received INCB001158 50 mg + pembrolizumab, which was half the recommended Phase 2 dose of INCB001158. In renally impaired participants, the 50 mg dose has comparable exposure to 100 mg in participants with normal renal function. It was pre-specified to combine Part 1c and Part 3 participants for efficacy analysis based on planned comparable dosing according to renal function.
