Brief Summary:
This is an open-label, multicenter Phase 1b/2 study to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of ARRY-382 in combination with pembrolizumab in adult patients with selected advanced solid tumors (Part A/Phase 1b); and to estimate the efficacy of the combination in three separate cohorts: 1) patients with advanced solid tumors that have progressed on prior PD-1/PD-L1inhibitors, 2) patients with platinum-resistant ovarian cancer and 3) patients with pancreatic ductal adenocarcinoma (Phase 2).

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors Drug: ARRY-382 Drug: Pembrolizumab Phase 1 Phase 2

Detailed Description:

ARRY-382 is an inhibitor of CSF1R (colony-stimulating factor-1 receptor).

Each phase of the study consists of a 28-day screening period; 21-day treatment cycles with the combination of ARRY-382 and pembrolizumab until disease progression as determined by the Investigator, unacceptable toxicity, withdrawal of consent, or death (or other discontinuation criteria are met), and a 30-day safety follow-up period. Patients in all cohorts/phases will be monitored for overall survival (OS) until 1 year after the date of the last patient's first visit.

Primary Outcome Measures :
  1. Phase 1b, Part A: Number of Participants With Dose-Limiting Toxicities (DLT) [ Time Frame: Cycle 1 (up to 21 days) ]
    DLT: adverse event (AE) or abnormal laboratory value not clearly attributable to an extraneous cause, such as disease progression, intercurrent illness, or concomitant medications occurring during 21 days of Cycle 1, met 1 of the criteria A) nonhematologic AEs: recurring grade 2 pneumonitis, grade 3 events (irAE, QTcF prolongation, rash; other grade 3/4 except alopecia, nausea, diarrhea, vomiting, tumor flare, pseudoprogression, endocrinopathy); B) hematology AEs/laboratory abnormalities: grade 4 events except lymphopenia, neutropenia, electrolyte imbalances or abnormalities, grade 3 thrombocytopenia, febrile neutropenia, grade 4 AST/ALT elevation, grade 3 AST/ALT elevation lasting >7 days, associated with bilirubin levels>=2*ULN or international normalized ratio >1.5, grade 3 bilirubin elevation >=3, CK elevation >=grade 3 lasting, increase in creatinine >=1.5*baseline value, dose delay (dose interruption for >14 days) or other (inability to receive at least 67% of ARRY-382 doses).

  2. Phase 2 Cohorts: Objective Response Rate (ORR) [ Time Frame: From day of first dose to 30 days after last dose (maximum up to 13.5 months) ]
    ORR was defined as the percentage of participants who achieved a best overall response (BOR) of complete response (CR) or partial response (PR) as determined by investigator review of radiographic disease assessments per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. As per RECIST v1.1: CR = disappearance of target and non-target lesions and normalization of tumor markers. Pathological lymph nodes must have short axis measures less than (<) 10 millimeter (mm). PR = at least a 30% decrease in the sum of measures (longest diameter for tumor lesions and short axis measure for nodes) of target lesions, taking as reference the baseline sum of diameters. Non-target lesions must be non-progressive disease (PD). The analysis was based on confirmed responses for which CR or PR must be confirmed by repeat disease assessment studies performed no less than 4 weeks after the criteria for response were first met to qualify as CR or PR, respectively.


Secondary Outcome Measures :
  1. Phase 1b, Part A: Objective Response Rate (ORR) [ Time Frame: From day of first dose to 30 days after last dose (maximum up to 34.7 months) ]
    ORR was defined as the percentage of participants who achieved a BOR of CR or PR as determined by investigator review of radiographic disease assessments per RECIST v1.1. As per RECIST v1.1: CR = disappearance of target and non-target lesions and normalization of tumor markers. Pathological lymph nodes must have short axis measures <10 mm. PR = at least a 30% decrease in the sum of measures (longest diameter for tumor lesions and short axis measure for nodes) of target lesions, taking as reference the baseline sum of diameters. Non-target lesions must be non-PD. The analysis was based on confirmed responses for which CR or PR must be confirmed by repeat disease assessment studies performed no less than 4 weeks after the criteria for response were first met to qualify as CR or PR, respectively.

  2. Phase 1b, Part A and Phase 2 Cohorts: Duration of Response (DOR) [ Time Frame: From date of first documented CR or PR up to disease progression or death (for Phase 1b: maximum up to 34.7 months, for Phase 2: maximum up to 13.5 months) ]
    DOR was defined as the time from the date of the first documented response (CR or PR) to the earliest date of disease progression, or death due to any cause after achieving a response. As per RECIST v1.1: CR = disappearance of target and non-target lesions and normalization of tumor markers. Pathological lymph nodes must have short axis measures < 10 mm. PR = at least a 30% decrease in the sum of measures (longest diameter for tumor lesions and short axis measure for nodes) of target lesions, taking as reference the baseline sum of diameters. PD = at least a 20% increase in the sum of diameters of measured lesions taking as references the smallest sum of diameters recorded on study (including baseline) and an absolute increase of >= 5 mm or appearance of at least 1 new lesion. Unequivocal progression of existing non-target lesions. DOR was estimated using the Kaplan-Meier method.

  3. Phase 1b, Part A and Phase 2 Cohorts: Progression-Free Survival (PFS) [ Time Frame: From day of first dose until disease progression or death due to any cause or till last tumor assessment date (for Phase 1b: maximum up to 34.7 months, for Phase 2: maximum up to 13.5 months) ]
    PFS was defined as the time from the date of first dose of study drug to the earliest date of disease progression per RECIST v1.1, or death due to any cause, whichever occurs first. If a participant did not have a PFS event at the time of the analysis cut-off or at the start of any new anticancer therapy, PFS was censored at the date of last adequate tumor assessment. PD = at least a 20% increase in the sum of diameters of measured lesions taking as references the smallest sum of diameters recorded on study (including baseline) and an absolute increase of >= 5 mm or appearance of at least 1 new lesion. Unequivocal progression of existing non-target lesions.

  4. Phase 1b, Part A and Phase 2 Cohorts: Overall Survival (OS) [ Time Frame: From day of first dose till death due to any cause or date of last contact (for Phase 1b: maximum up to 34.7 months, for Phase 2: maximum up to 13.5 months) ]
    OS was defined as the time from the start of treatment to the date of death due to any cause. If a death was not observed by the date of the analysis cut-off, OS was censored at the date of last contact. OS was estimated using the Kaplan-Meier method.

  5. Phase 1b, Part A and Phase 2 Cohorts: Percentage of Participants With Immune-Related Response Rate (irRR) [ Time Frame: From day of first dose till up to end of study treatment (for Phase 1b: maximum up to 33.7 months, for Phase 2: maximum up to 12.5 months) ]
    irRR was defined as the percentage of participants who achieved immune-related best overall response (irBOR) of immune-related CR (irCR) or immune-related PR (irPR), as determined by the investigator per immune related response criteria (irRC). irBOR was the best response using irRC recorded from the start of study treatment until the end of treatment. irCR was the disappearance of all target lesions, irPR was a decrease in tumor burden by 50% or greater by a consecutive assessment at least 4 weeks after first documentation.

  6. Phase 1b, Part A and Phase 2 Cohorts: Immune-Related Progression-Free Survival (irPFS) [ Time Frame: From the start of treatment to the time of first documented progression, or death (for Phase 1b: maximum up to 34.7 months, for Phase 2: maximum up to 13.5 months) ]
    irPFS was defined as the time from the start of treatment to the time of first documented progression per irRC, or death due to any cause. irRC criteria for progression for 1) Measurable new lesions: incorporated into the tumor burden (eg, added to the index lesions); do not define progression unless the total measurable tumor burden increases by the required amount (25%); 2) New non-measurable lesions: not considered progression if the total measurable tumor burden is stable or shrinking. For the analysis of irPFS, Kaplan-Meier method was used.
