Clinical Trial Summary

This study is being done to see if combining liposomal irinotecan with TAS102 and bevacizumab confers clinical benefit for patients with treatment refractory metastatic colorectal cancer.

Description:

This prospective phase II, single arm, single site trial will evaluate the efficacy of the combination of liposomal irinotecan (nal-IRI), TAS102, and bevacizumab for the treatment of patients with mismatch repair proficient, metastatic or unresectable colorectal cancer that has previously been treated with 5-fluorouracil, oxaliplatin, irinotecan and if RAS wild-type an anti-EGFR agent. A total of 25 patients will be accrued at UW Carbone Cancer Center. Subject enrollment will occur over 12 months with the total duration of the trial expected to be 3 years.

Primary Objective

• To determine the progression free survival (PFS) of patients with metastatic colorectal cancer treated in the treatment refractory setting with liposomal irinotecan in combination with TAS102 and bevacizumab.

Secondary Objectives

• To evaluate the objective response rate (ORR) of liposomal irinotecan in combination with bevacizumab and TAS102.

• To assess the safety and tolerability of these regimens in this setting.

• To determine the impact of the timing of irinotecan use in prior lines of therapy on the ORR and PFS observed with these nal-IRI containing treatment regimens

Eligibility

Inclusion Criteria:

• Patients must be = 18 years of age

• Eastern Cooperative Oncology Group (ECOG) performance must be 0 or 1.

• Patients must have a histologically or cytologically confirmed diagnosis of colorectal adenocarcinoma and be metastatic or unresectable.

• The cancer must be mismatch repair proficient.
