Participant Flow
Recruitment Details | This study had 2 phases: Phase 1B and 2. Originally, Phase 1b of the study had Part A and B. Part A was dose escalation in participants with selected advanced solid tumors. Part B was expansion in melanoma participants. Part C was a part of Phase 2, in participants with non-small cell lung cancer (NSCLC). |
Pre-assignment Details | There was an amendment in protocol, which removed originally designed Part B and C, due to low enrolment. Post-implementation of this amendment 2, Part B and C were replaced with 3 cohorts in Phase 2. Study then had Part A (Phase 1b), and 3 cohorts in Phase 2. Cohorts of Phase 2 were as follows: 1) PD-1/PD-L1 inhibitor-refractory cohort, 2) pancreatic ductal adenocarcinoma cohort and 3) platinum-resistant ovarian cancer cohort. |

Arm/Group Description | Participants with selected advanced solid tumors received ARRY-382 capsules at a dose of 200 milligrams (mg) orally, once daily (QD) in combination with pembrolizumab at a dose of 2 milligram per kilogram (mg/kg) intravenously (IV) every 3 weeks (Q3W) in each 21-day treatment cycle until disease progression, participant refusal, lost to follow-up, unacceptable toxicity, or the study termination by the sponsor and a 30-day safety follow-up period. | Participants with selected advanced solid tumors received ARRY-382 capsules at a dose of 300 mg orally, QD in combination with pembrolizumab at a dose of 2 mg/kg IV Q3W in each 21-day treatment cycle until disease progression, participant refusal, lost to follow-up, unacceptable toxicity, or the study termination by the sponsor and a 30-day safety follow-up period. | Participants with selected advanced solid tumors received ARRY-382 capsules at a dose of 400 mg orally, QD in combination with pembrolizumab at a dose of 2 mg/kg IV Q3W in each 21-day treatment cycle until disease progression, participant refusal, lost to follow-up, unacceptable toxicity, or the study termination by the sponsor and a 30-day safety follow-up period. | Participants with melanoma received ARRY-382 capsules at a dose of 300 mg orally, QD in combination with pembrolizumab at a dose of 2 mg/kg IV Q3W in each 21-day treatment cycle until disease progression, participant refusal, lost to follow-up, unacceptable toxicity, or the study termination by the sponsor and a 30-day safety follow-up period. | Participants with NSCLC received ARRY-382 capsules at a dose of 300 mg orally, QD in combination with pembrolizumab at a dose of 2 mg/kg IV Q3W in each 21-day treatment cycle until disease progression, participant refusal, lost to follow-up, unacceptable toxicity, or the study termination by the sponsor and a 30-day safety follow-up period. | Participants who progressed on a programmed cell death receptor 1 (PD-1)/ programmed cell death ligand 1 (PD-L1) inhibitor-containing regimen as their most recent prior line of therapy and were new to prior colony-stimulating factor 1 receptor (CSF-1R) or colony-stimulating factor 1(CSF-1) inhibitors were included in this reporting arm. Participants received ARRY-382 capsules at a dose of 300 mg orally, QD in combination with pembrolizumab at a dose of 200 mg IV Q3W in each 21-day treatment cycle until disease progression, participant refusal, lost to follow-up, unacceptable toxicity, or the study termination by the sponsor and a 30-day safety follow-up period. | Participants with PDA who had at least 1 prior line of therapy and were new to prior checkpoint inhibitor (CPI) therapy and to prior CSF-1R or CSF-1 inhibitors were included in this reporting arm. Participants received ARRY-382 capsules at a dose of 300 mg orally, QD in combination with pembrolizumab at a dose of 200 mg IV Q3W in each 21-day treatment cycle until disease progression, participant refusal, lost to follow-up, unacceptable toxicity, or the study termination by the sponsor and a 30-day safety follow-up period. | Participants with prOVCA who had at least 1 prior line of therapy and were new to prior CPI therapy and to prior CSF-1R or CSF-1 inhibitors were included in this reporting arm. Participants received ARRY-382 capsules at a dose of 300 mg orally, QD in combination with pembrolizumab at a dose of 200 mg IV Q3W in each 21-day treatment cycle until disease progression, participant refusal, lost to follow-up, unacceptable toxicity, or the study termination by the sponsor and a 30-day safety follow-up period. |
