NCT03597581 · Status: COMPLETED · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 89

Last updated 2025-04-03

No results posted yet for this study

Summary

This is a Phase 1 study currently evaluating PO administered ompenaclid in combination with FOLFIRI and bevacizumab in patients with advanced (i.e., locally advanced and unresectable, or metastatic) previously treated colorectal adenocarcinoma. The single agent ompenaclid dose escalation stage and the ompenaclid in combination with FOLFIRI and bevacizumab dose escalation stage of the study has been completed; the expansion stage of ompenaclid in combination with FOLFIRI and bevacizumab is ongoing. In April-24 a protocol amendment added a new dose escalation and expansion stage which will evaluate ompenaclid in combination with FOLFOX and bevacizumab in patients with metastatic CRC. It is anticipated that a total of 30 patients will be enrolled in this new dose escalation and expansion stage of the study.

Conditions

Interventions

DRUG

ompenaclid

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

DRUG

FOLFIRI

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

DRUG

Bevacizumab

Bevacizumab is a vascular endothelial growth factor inhibitor.

DRUG

FOLFOX regimen

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
