Pancreatic Cancer | Drug: Avelumab Drug: Binimetinib Drug: Talazoparib | Phase 1 Phase 2 |
This is a Phase 1b/2, open label, multi-center, safety, clinical activity, pharmacokinetic (PK), and pharmacodynamics (PD) study of combinations of avelumab, binimetinib and talazoparib in adult patients with metastatic pancreatic ductal adenocarcinoma and other locally advanced or metastatic KRAS- or NRAS-mutant solid tumors.
The Phase 1b part of this study will initially assess doublet drug combinations to determine a recommended dose for further investigation. Following this, the recommended dose for the combination of avelumab, binimetinib and talazoparib (triplet) will be determined. The recommended doses for the doublet and triplet combinations will be used in the Phase 2 part of the study, which will assess the safety and preliminary anti-tumor activity of the study treatments.

- Dose Limiting Toxicity (DLT) [ Time Frame: Cycle 1 (days 1-28 of study treatment) ]Phase 1: DLT during the primary DLT evaluation period (Cycle 1)
- Confirmed Objective Response (OR) [ Time Frame: From start date (date of randomization for randomized cohorts and first dose of study treatment for non-randomized cohorts) until the date of first documentation of progressive disease or death due to any cause assessed up to approximately 24 months. ]Phase 2: Confirmed OR, defined as a complete response (CR) or partial response (PR) per RECIST v1.1. Both CR and PR must be confirmed by repeat assessments performed no less than 4 weeks after the criteria for response are first met.
- Concentration of avelumab in blood [ Time Frame: Day 1, Day 8 and Day 15 of Cycle 1 (each cycle is 28 days); Day 1 and Day 15 of Cycle 2; and Day 1 of Cycles 3, 5, 9 and 12. ]Pharmacokinetic parameters: pre-dose/trough concentrations (Ctrough)
- Concentration of avelumab in blood [ Time Frame: Day 1, Day 8 and Day 15 of Cycle 1 (each cycle is 28 days); Day 1 and Day 15 of Cycle 2; and Day 1 of Cycles 3, 5, 9 and 12. ]Pharmacokinetic parameters: post dose concentrations (Cmax)
- Avelumab ADA levels [ Time Frame: Day 1, Day 8 and Day 15 of Cycle 1 (each cycle is 28 days); Day 1 and Day 15 of Cycle 2; and Day 1 of Cycles 3, 5, 9 and 12. ]Immunogenicity assessment of avelumab
- Neutralizing antibodies (nAb) against avelumab. [ Time Frame: Day 1, Day 8 and Day 15 of Cycle 1 (each cycle is 28 days); Day 1 and Day 15 of Cycle 2; and Day 1 of Cycles 3, 5, 9 and 12. ]Immunogenicity assessment of avelumab
- Concentration of binimetinib in plasma [ Time Frame: Pre-dose on Day 1, Day 8 and Day 15 of Cycle 1 (each cycle is 28 days). Day 1 of Cycle 2 and 3 ]Pharmacokinetic parameters: pre-dose/trough concentrations (Ctrough)
- Concentration of binimetinib in plasma [ Time Frame: Day 1, Day 8 and Day 15 of Cycle 1 (each cycle is 28 days). Day 1 of Cycle 2 and Cycle 3. ]Pharmacokinetic parameters: post dose concentrations (Cmax).
- Concentration of talazoparib in plasma [ Time Frame: Pre-dose on Day 1, 8 and Day 15 of Cycle 1 (each cycle is 28 days), and on Day 1 of Cycle 2 and 3 ]Pharmacokinetic parameters: pre-dose/trough concentrations (Ctrough)
- Biomarker Tumor Mutational Burden [ Time Frame: Baseline ]Tumor mutational burden in baseline tumor tissue
- Biomarker PD-L1 [ Time Frame: Baseline ]PD-L1 expression level in baseline tumor tissue.
- Biomarker DNA Damage Repair [ Time Frame: Baseline ]DDR gene alterations in baseline tumor tissue.
- Objective Response [ Time Frame: From the start of treatment until disease progression/recurrence up to approximately 24 months. ]Phase 1b: Confirmed OR based on Investigator assessment per RECIST v1.1.
- Time to Tumor Response (TTR) [ Time Frame: Baseline up to approximately 24 months ]TTR is defined, for patients with an OR, as the time from the 'start date' to the first documentation of objective response (CR or PR) which is subsequently confirmed
- Duration of Response (DR) [ Time Frame: Baseline up to approximately 24 months ]DR is defined, for patients with OR, as the time from the first documentation of objective response (CR or PR) to the date of first documentation of PD or death due to any cause
- Overall Survival (OS) [ Time Frame: Baseline up to approximately 24 months ]OS is defined as the time from time from the 'start date' to the date of death due to any cause. Patients without an event (death) will be censored at the date of last contact
- Progression Free Survival [ Time Frame: Baseline up to approximately 24 months ]PFS is defined as the time from 'start date' to the date of PD by RECIST v1.1 or death due to any cause, whichever occurs first
