NCT03106415

Brief Summary

This phase I/II trial studies the best dose of pembrolizumab and binimetinib and how well it works when given together with pembrolizumab in treating patients with triple negative breast cancer that has spread to other parts of the body (metastatic). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and binimetinib may work better in treating patients with triple negative breast cancer.

Outcome Measures

Primary Outcomes (2)

  • Maximum Tolerated Dose (MTD) of Pembrolizumab in Combination With Binimetinib Using the Standard 3+3 Design (Phase I)

    Will be assessed by Common Terminology Criteria for Adverse Events version 4.0. Safety/adverse events data will be tabulated, including adverse events of all grades.

    35 days

  • Objective Response Rate (ORR) as (Phase II)

    Will be assessed by Response Evaluation Criteria in Solid Tumors (RECIST). Will utilize Simon's Two-Stage Optimal Design to test the null hypothesis. Will be estimated using the approach of Jung and Kim. The 90% lower confidence bound will be calculated using the approach of Koyama and Chen. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

    3 years

Secondary Outcomes (3)

  • ORR by Immune-related RECIST Criteria (irRECIST)

    Up to 3 years

  • Progression Free Survival (PFS)

    The time from study enrollment to date of progression, assessed up to 3 years

  • Overall Survival (OS)

    The time from study enrollment to death attributable to any cause, assessed up to 3 years

Study Arms (1)

Treatment (binimetinib, pembrolizumab)

EXPERIMENTAL

Patients receive binimetinib PO BID on days 1-14 of cycle 1 and on days 1-21 of cycle 2 and subsequent cycles. Beginning cycle 2, patients also receive pembrolizumab IV over 30 minutes on day 1. Cycle 1 equals 14 days. Cycles 2 and beyond repeat every 21 days in the absence of disease progression or unacceptable toxicity.
