CPI-613 (Devimistat) in Combination With Modified FOLFIRINOX Plus Bevacizumab in Patients With Metastatic Colorectal Cancer

• Status: Not yet recruiting
• Trial end date: 2023-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Pre-clinical in vitro and in vivo data as well as early phase 1 clinical trials have shown that both hematologic and solid tumor cells are susceptible to single-agent cytotoxicity by CPI-613 (devimistat), consistent with its selective target of the altered form of mitochondrial energy metabolism in tumor cells, causing changes in mitochondrial enzyme activities and redox status, which lead to apoptosis, necrosis, and autophagy of tumor cells leading to the death of cancer cells. It is our hypothesis that CPI-613 (devimistat) will enhance the efficacy of mFOLFIRINOX plus Bevacizumab when given as a combination treatment. The study will follow a standard 3+3 design. Cohorts of three to six patients will be treated at each dose level until the MTD is defined.

• Phase: Phase 1
