Safety and Efficacy of Anlotinib in Combination With Irinotecan in Patients With Pretreated Advanced Colorectal Cancer

Phase 1

• Conditions: Colo-rectal Cancer
• Interventions: Drug: Anlotinib Hydrochloride with Irinotecan

• Registration Number: NCT03545711
• Lead Sponsor: Chinese Academy of Medical Sciences

Brief Summary

Patients with pretreated advanced colorectal cancer are recruited to the phase I portion of this prospective non-randomised study in an escalated dose cohort. The primary endpoint of the dose-escalation phase is to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of anlotinib when given in combination with irinotecan. The phase II (dose-expansion) portion is designed to characterize the safety and potential efficacy of the combination therapy in pretreated advanced colorectal cancer patients.
