University of Wisconsin, Madison

Start Date

Completion Date

7/1/2028

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.

Detailed 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 Criteria

Age Range: 18 years to No maximum

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. * Patients must have had prior treatment with 5-fluorouracil, oxaliplatin, irinotecan containing regimens. If RAS wild-type must have received prior anti-EGFR therapy with either cetuximab or panitumumab. If RAS wild-type and HER2 positive then must have had a prior HER2 targeted therapy. Exclusion Criteria: * Uncontrolled concurrent medical illness that would not allow for the completion of the planned therapy. * Patients whose cancers possess BRAF V600 mutations are excluded. * Patients must stop the use of strong inducers/inhibitors of CYP3A4 at least 2 weeks before initiating therapy. * Patients must not have mismatch repair deficient or microsatellite instability high cancers. * Patients must not have received prior TAS102.
