A Study of RGX-202-01 (Ompenaclid) as Combination Therapy in RAS Mutant Advanced Colorectal Cancer

RGX-202-01 (ompenaclid) is a small molecule inhibitor of the creatine transporter, SLC6a8.

FOLFIRI is a chemotherapy regimen consisting of irinotecan, leucovorin, and 5-fluorouracil. Irinotecan is a topoisomerase inhibitor, which prevents DNA from uncoiling and duplicating.

Bevacizumab is a vascular endothelial growth factor inhibitor.

The FOLFOX regimen used for this protocol consists of oxaliplatin given at 85 mg/m2 IV together with leucovorin at 400 mg/m2 IV (substitution with levo-leucovorin 200 mg/m2 IV is allowed) (duration per institutional policy), followed by a 5-FU bolus of 400 mg/m2 (over 2-5 minutes), and then continuous infusional 5-FU given at a dose of 2400 mg/m2 over 46-48 hours (1200 mg/m2/day), given on Days 1 and 15 of each 28-day cycle. A minimum of 8 FOLFOX cycles should be received if tolerated per standard of care guidelines
