Abstract | BACKGROUND: METHODS: This Phase I study investigated the safety, tolerability and pharmacokinetics of cediranib (20 or 30 mg) in combination with mFOLFOX6 in Japanese patients with previously untreated metastatic CRC. If the safety of the 20 mg dose was confirmed, a second cohort of patients was to be recruited to receive cediranib 30 mg + mFOLFOX6. RESULTS: Six patients received cediranib 20 mg + mFOLFOX6 and seven received cediranib 30 mg + mFOLFOX6. One patient in the initial cediranib 20 mg cohort experienced a dose-limiting toxicity (DLT; grade 3 bilirubin increase); no DLTs were observed in the 30 mg cohort. The most commonly reported adverse events were diarrhea, decreased appetite, peripheral neuropathy, hypertension and fatigue. Two patients in the 20 mg cohort and three in the 30 mg cohort experienced serious adverse events during all treatment courses. Cediranib was generally well tolerated in this patient population with no evidence to suggest any significant pharmacokinetic interactions between cediranib and fluorouracil or oxaliplatin. A preliminary evaluation showed that five of nine evaluable patients achieved a best response of partial response. CONCLUSION:
Cediranib (20 or 30 mg) in combination with mFOLFOX6 was considered tolerable according to the protocol-defined criteria, providing justification for the Phase II part of this study.
