5. Study Description

Brief Summary
This Phase 1b/2 study will examine the effects of the study drugs, avelumab, binimetinib and talazoparib when given in a 2 (doublet) or 3 (triplet) drug combination, in patients with locally advanced or metastatic RAS-mutant solid tumors. The Phase 1b part of the study will assess if the different study drugs can be given together safely and which doses to use for further research. Phase 2 will test if the study treatments have an effect on tumor size and growth, and gather more information about potential side effects.
Detailed Description
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.
