Overview

Study Title

Phase I study of Regorafenib and Nivolumab in Mismatch Repair (MMR) Proficient Advanced Refractory Colorectal Cancer

Summary

Objective

Primary Objective 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 1. To access response rate using RECIST criteria 2. To access overall survival 3. To further evaluate the frequency and severity of adverse events and tolerability of the combination regimen. Exploratory Objectives 1. To evaluate potential correlations between blood or tumor biomarkers and clinical outcome.

Inclusion Criteria

  • Histologically confirmed diagnosis of colorectal adenocarcinoma
  • Proficient DNA mismatch repair (MMR) or stable microsatellite disease confirmed by immunohistochemical staining or PCR
  • Patients with the presence of at least one lesion with measurable disease as defined by 10mm in longest diameter for a soft tissue lesions or 15mm in short axis for a lymph node by RECIST 1.1 for response assessment
  • Patients must have received and progressed through or become intolerant to fluoropyrimidine, irinotecan, oxaliplatin, and bevacizumab, and if K-ras wild type, cetuximab or panitumumab containing therapies. Prior TAS 102 is allowed
  • ECOG Performance Score 0 or 1

  • Patients must not have had chemotherapy, major surgery, monoclonal antibody therapy or experimental therapy within the 21 days prior to the start of regorafenib and nivolumab administration
  • Women of childbearing potential must have a negative serum or urine pregnancy test performed within 24 hours prior to the start of study drug and then every 4 weeks. Post-menopausal women and surgically sterilized women are not required to undergo a pregnancy test.
  • Patients (men and women) of childbearing potential must agree to use adequate contraception beginning at the signing of the ICF until at least 5 months for females and 7 months for males after the last dose of study drug
  • Patients must be able to understand and be willing to sign the written informed consent formand be willing and able to comply with scheduled visits, treatment schedule, laboratory testing, and other study requirements.

  • Women who are pregnant or breast-feeding
  • Prior therapy with regorafenib, anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell costimulation or checkpoint pathways).
  • Previous or concurrent cancer within 3 years prior to treatment. Some exclusions apply.
  • Active autoimmune disease that has required systemic treatment in the past 2 years. Replacement therapy is not considered a form of systemic treatment.
  • Ascites, pleural effusion, or pericardial fluid requiring drainage in the last 4 weeks.
