Brief summary

This will be a randomized, open-label, multicenter, Phase II study with primary objectives to assess whether expression of select chemotherapy markers is associated with progression-free survival (PFS) in participants treated with bevacizumab plus leucovorin, 5-fluorouracil, and oxaliplatin (mFOLFOX6) or bevacizumab plus leucovorin, 5-fluorouracil, and irinotecan (FOLFIRI). The study population will consist of participants with first-line mCRC.

Interventions

DRUG5-Fluorouracil

5-Fluorouracil 400 milligrams per meter-squared (mg/m\^2) by IV bolus and subsequent 2400 mg/m\^2 by IV infusion over 46 hours will be administered every 2 weeks until disease progression or unacceptable toxicity.

DRUGBevacizumab

Bevacizumab 5 milligrams per kilogram (mg/kg) of body weight via IV infusion will be administered every 2 weeks until disease progression or unacceptable toxicity. If participants are discontinued from oxaliplatin or irinotecan due to unacceptable toxicity, bevacizumab may be given in 3-week cycles with capecitabine.

DRUGIrinotecan

Irinotecan 180 mg/m\^2 via IV infusion over 2 hours will be administered every 2 weeks until disease progression or unacceptable toxicity.

DRUGLeucovorin

Leucovorin 400 mg/m\^2 or dose deemed appropriate by Investigator via IV infusion over 2 hours will be administered every 2 weeks until disease progression or unacceptable toxicity.

DRUGOxaliplatin

Oxaliplatin 85 mg/m\^2 via IV infusion over 2 hours will be administered every 2 weeks until disease progression or unacceptable toxicity.

DRUGCapecitabine

Capecitabine 850 or 1000 mg/m\^2 may be offered in the event of unacceptable toxicity to oxaliplatin or irinotecan, to be given orally twice a day on Days 1 to 14 in 3-week cycles.

Outcome results

PFS According to RECIST Version 1.1 in Participants With High ERCC-1 Levels

Tumor assessments were performed according to RECIST Version 1.1. Disease progression was defined as ≥20% increase in sum of LD of target lesions in reference to the smallest sum of LD on study, in addition to an absolute increase ≥5 mm. Disease progression was further defined as the last documented progression determined by the Investigator no later than 1 day before initiation of second-line therapy. Death on study included death from any cause occurring no later than 3 months after the last component of study treatment. PFS was defined as the time from randomization to death or disease progression, whichever occurred first. The median duration of PFS was estimated by Kaplan-Meier analysis and expressed in months. The 95% CI was computed using the method of Brookmeyer and Crowley.

Time frame: From Baseline until death or disease progression; assessed every 6 weeks (maximum up to 45 months overall)

Population: ITT Population. The Number of Participants Analyzed reflects the number of evaluable participants for the outcome measure.

R1 was defined as the presence of exposed tumor or histologically detected tumor cells at the line of transection, or \<1 mm microscopic margins. In the case of use of radiofrequency ablation or cryotherapy, the resection was considered as R1. R2 was defined as macroscopic positive margins or incomplete resection at time of surgery. The percentage of participants with resection of liver or liver plus lymph node metastases was reported. The 95% CI was computed using normal approximation to the binomial distribution.

PFS According to RECIST Version 1.1 in Participants With High ERCC-1 and High VEGF-A Levels

Tumor assessments were performed according to RECIST Version 1.1. Disease progression was defined as ≥20% increase in sum of LD of target lesions in reference to the smallest sum of LD on study, in addition to an absolute increase ≥5 mm. Disease progression was further defined as the last documented progression determined by the Investigator no later than 1 day before initiation of second-line therapy. Death on study included death from any cause occurring no later than 3 months after the last component of study treatment. PFS was defined as the time from randomization to death or disease progression, whichever occurred first. The median duration of PFS was estimated by Kaplan-Meier analysis and expressed in months. The 95% CI was computed using the method of Brookmeyer and Crowley.
