Study to Compare CAPTEM vs FOLFIRI as Second Line Treatment in Advanced, Colorectal Cancer Patients

Summary

Open-label, randomized, multicenter, Phase II trial designed to estimate the efficacy of CAPTEM versus FOLFIRI as second line treatment in MGMT methylated, RAS mutated advanced CRC patients who have progressed on or after first-line oxaliplatin containing chemotherapy for metastatic disease. MGMT will be assessed centrally at Pathology Department of Fondazione IRCCS Istituto Nazionale dei Tumori prior to enrollment. A minimum of ten 3-micron unstained sections on charged slides of tumor will be required and methylation status will be provided within a maximum of seven days to the Study Centers. Presence of RAS mutation will be assessed at each local participating center. Eligible patients will be randomized in a 1:1 ratio to one of two treatment arms:

* Arm A (experimental arm): CAPTEM
* Arm B (control arm): FOLFIRI Study treatment will be given in cycles repeated every 28 days for Arm A and every 14 days for Arm B. Patients in Arm A will receive capecitabine at the oral dose of 1500 mg/mq/die bid from day 1 to day 14 every 28 days plus temozolomide 150 mg/mq/die bid starting on day 9 to 14 every 28 days. Patients in Arm B will receive FOLFIRI chemotherapy starting Day 1 q2w (every cycle) starting on Day 1 of Cycle 1. FOLFIRI consists of irinotecan (starting dose of 180 mg/m2) on day one only; 5-FU 7 (starting bolus and 22-hour infusional doses of 400 mg/m2 and 600 mg/m2, respectively), and leucovorin (racemic, starting dose of 200 mg/m2 or L-form, starting dose of 100 mg/m2) for two consecutive days. Treatment will continue for up to 6 cycles in Arm A and up to 12 cycles in Arm B or up to disease progression, unacceptable toxicity or informed consent withdrawal. Randomization will be stratified across the treatment arms by the following predefined stratification variables: disease progression within 9 months from the start of first-line oxaliplatin-containing chemotherapy (\< vs. ≥9 months); prior bevacizumab in combination with oxaliplatin-based chemotherapy (yes vs. no). Efficacy assessments will be performed every 2 cycles in Arm A and every 4 cycles in Arm B until progression. The study is expected to enrol approximately 82 patients who meet the eligibility criteria.

Interventions

DRUG

Capecitabine

Patients in Arm A will receive capecitabine at the oral dose of 1500 mg/mq/die refracted in two daily doses from day 1 to day 14 every 28 days

DRUG

Temozolomide

Patients in Arm A will receive temozolomide 150 mg/mq/die refracted in two daily doses starting on day 10 to 14 every 28 days.

DRUG

Irinotecan

Patients in Arm B will receive FOLFIRI chemotherapy starting Day 1 q2w (every cycle) starting on Day 1 of Cycle 1. FOLFIRI consists of irinotecan (starting dose of 180 mg/m2) on day one only; 5-FU (starting bolus and 22-hour infusional doses of 400 mg/m2 and 600 mg/m2, respectively), and leucovorin (racemic, starting dose of 200 mg/m2 or L-form, starting dose of 100 mg/m2) for two consecutive days.

DRUG

Patients in Arm B will receive FOLFIRI chemotherapy starting Day 1 q2w (every cycle) starting on Day 1 of Cycle 1. FOLFIRI consists of irinotecan (starting dose of 180 mg/m2) on day one only; 5-FU (starting bolus and 22-hour infusional doses of 400 mg/m2 and 600 mg/m2, respectively), and leucovorin (racemic, starting dose of 200 mg/m2 or L-form, starting dose of 100 mg/m2) for two consecutive days.

DRUG

Leucovorin

Patients in Arm B will receive FOLFIRI chemotherapy starting Day 1 q2w (every cycle) starting on Day 1 of Cycle 1. FOLFIRI consists of irinotecan (starting dose of 180 mg/m2) on day one only; 5-FU (starting bolus and 22-hour infusional doses of 400 mg/m2 and 600 mg/m2, respectively), and leucovorin (racemic, starting dose of 200 mg/m2 or L-form, starting dose of 100 mg/m2) for two consecutive days.
