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.

Condition or disease Intervention/treatment Phase
Pancreatic Cancer Drug: Avelumab Drug: Binimetinib Drug: Talazoparib Phase 1 Phase 2

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.

    Confirmed OR, defined as a complete response (CR) or partial response (PR) per RECIST v1.1. CR was defined as complete disappearance of all target and non-target lesions, with the exception of nodal disease and sustained for at least 4 weeks. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (<) 10 mm. PR was defined as at least 30% decrease in the sum of the longest dimensions of target lesions taking as reference the baseline sum longest dimensions. Both CR and PR must be confirmed by repeated assessments performed no less than 4 weeks after the criteria for response were first met.

    An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent adverse event (TEAE) means event between first dose of study treatment and up to 30 days after last dose that were absent before treatment or that worsened relative to pretreatment state. An SAE was an AE resulting in any of death; inpatient hospitalization; life-threatening experience; disability; congenital anomaly or deemed significant for any other reason. Symptoms of infusion-related reactions (IRRs) may include, but were not limited to, fever, chills, flushing, hypotension, dyspnea, wheezing, back pain, abdominal pain, and urticaria.
