Conditions: Colorectal Cancer
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 5
Healthy volunteers: no

Brief summary:
The purpose of the Phase Ib portion is to find out the highest dose of study drug that can safely be given when tested in a small group of subjects.

The purpose of the Phase II portion is to find out how safe the study drug is when taken at the highest dose in a larger group of subjects.

Detailed description:
The primary purpose for Phase 1b: to determine the maximum tolerated dose (MTD) of E7820 recommended for Phase 2 when administered in combination with the FOLFIRI regimen (irinotecan, leucovorin, and 5-fluorouracil \[5-FU\]) in participants with locally advanced or metastatic colorectal cancer (mCRC) who have failed first-line therapy. Phase 2: to evaluate the safety and tolerability of E7820 administered in combination with the FOLFIRI regimen, compared with FOLFIRI alone and FOLFIRI plus bevacizumab, in patients with locally advanced or mCRC who have failed first-line therapy.

Arms:
arm 1: The FOLFIRI regimen consists of irinotecan at 180 mg/m2 (IV infusion) on Day 1 and Day 15 of each 28-day cycle, leucovorin at 200 mg/m2 (400 mg/m2 if using d,l-racemic mixture of leucovorin) by IV infusion on Days 1 and 15 of each cycle, and 5-FU at 400 mg/m2 as an IV bolus injection followed by a total of 2400 mg/m2 by CIV infusion over 46 hours over Days 1 and 2 via an ambulatory programmable pump (the use of an ambulatory pump is optional). The 5-FU IV bolus (400 mg/m2) and CIV infusion (2400 mg/m2) over 46 hours is repeated on Days 15 and 16 of each cycle. arm 2: E7820 is administered orally in tablet form once daily, every day of each 28-day treatment cycle. For the Phase Ib portion, the doses will be 40 mg/day, 70 mg/day, and 100 mg/day, and for the Phase II portion, the dose will be the MTD recommended Phase IB dose in combination with FOLFIRI, as determined during the Phase Ib portion of the study. arm 3: Bevacizumab at 5 mg/kg (IV infusion) on Days 1 and 15 of each 28-day treatment cycle
