Regorafenib and Nivolumab in Treating Regorafenib and Nivolumab in Mismatch Repair (MMR) Proficient Advanced Refractory Colorectal Cancer

Status: Active

Description

This phase I trial studies the side effects and best dose of regorafenib when given with nivolumab in treating patients with mismatch repair proficient colorectal cancer that has spread to other places in the body (advanced) and does not respond to treatment (refractory). Regorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving regorafenib and nivolumab may work better in treating colorectal cancer.

Trial Objectives and Outline

PRIMARY OBJECTIVE:

I. To assess safety and tolerability, describe the dose-limiting toxicities (DLTs), and determine the maximum tolerated dose (MTD) or the highest protocol-defined dose level in the absence of establishing an MTD of regorafenib in combination with nivolumab in subjects with advanced, refractory colorectal cancers.

SECONDARY OBJECTIVES:

I. To assess response rate using Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

II. To assess overall survival.

III. To further evaluate the frequency and severity of adverse events and tolerability of the combination regimen.

EXPLORATORY OBJECTIVE:

I. To explore potential correlation of biomarkers to predict clinical response of the combination therapy.

OUTLINE: This is a dose-escalation study of regorafenib.

Patients receive regorafenib (PO) daily on days 1-21 and nivolumab intravenously (IV) over 60 minutes on days 1 and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 100 days, then every 12 weeks thereafter.
