Brief summary

This phase II trial studies how well TAS-102, irinotecan, and bevacizumab work in treating patients with pre-treated colorectal cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Drugs used in chemotherapy, such as TAS-102, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Irinotecan may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with bevacizumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving TAS-102, irinotecan, and bevacizumab may work better in treating patients with colorectal cancer compared to traditional chemotherapy and bevacizumab.

Detailed description

PRIMARY OBJECTIVE: I. Determine the median progression free survival (PFS) benefit of leucovorin calcium, 5-fluorouracil, and irinotecan (FOLFIRI) naive patients treated with trifluridine and tipiracil hydrochloride (TAS-102) + irinotecan + bevacizumab as compared to historic control groups treated with FOLFIRI + bevacizumab. SECONDARY OBJECTIVE: I. Estimate the objective response rate (ORR), median overall survival (OS), and adverse event (AE) profile. OUTLINE: Patients receive irinotecan intravenously (IV) over 90 minutes and bevacizumab IV over 30-90 minutes on days 1 and 15. Patients also receive trifluridine and tipiracil hydrochloride orally (PO) twice daily (BID) on days 2-6 and 16-20. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days and then every 6 months for up to 2 years.

Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately * Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure

Exclusion criteria

* Prior treatment with TAS-102 or irinotecan * Anti-cancer therapy within 2 weeks of the planned first dose of study medication * Unresolved toxicities from prior therapy of \> grade 1, excluding alopecia or similar toxicities which are not deemed to be clinically significant or put the participant at greater risk. Grade 2 neuropathy is permitted * Major surgery within 4 weeks of anticipated start of therapy * Uncontrolled hypertension: systolic blood pressure \>= 150, diastolic blood pressure \>= 100 * Unstable angina, symptomatic congestive heart failure or cardiac arrhythmia requiring anti-arrhythmic therapy (beta-blockers, calcium channel blockers and digoxin are allowed) * Arterial or venous thrombotic or embolic events within 3 months of study initiation, unless well controlled on stable anti-coagulation for \>= 2 weeks. This excludes uncomplicated catheter associated venous thrombosis * History of cerebrovascular or myocardial ischemia within 6 months of initiation * National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0 grade 3 or greater hemorrhage within the past 4 weeks * Proteinuria \>= 2+, unless 24 hour urine collection demonstrates =\< 1 g of protein OR spot protein: creatinine demonstrates a ratio of =\< 1 * Untreated brain metastases * History of abnormal glucuronidation of bilirubin (Gilbert's syndrome) * History of second primary malignancy within 3 years prior to enrollment, excluding in-situ cervical carcinoma, non-melanoma skin cancer or malignancy of equivalent risk which is highly unlikely to require systemic treatment in the next 2 years * Have known active infection which would heighten the risk of complications * Pregnant or nursing female participants * Unwilling or unable to follow protocol requirements * Any condition which in the investigator's opinion deems the participant an unsuitable candidate to receive study drug

Design outcomes

Primary

MeasureTime frameDescription
Median Progression Free Survival (PFS)Medical record review will be performed approximately every 6 months, for up to 2 years, post treatment up to 4 yearsWill be assessed via the Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 guidelines. The PFS will be summarized using standard Kaplan-Meier methods, where estimates of the median PFS and 6/12-month PFS rates will be obtained with 90% confidence intervals.

Secondary

MeasureTime frameDescription
Number of Participants With Complete Response, Partial Response, Stable Disease and Progressive DiseaseMedical record review will be performed approximately every 6 months, for up to 2 years, post treatment up to 4 yearsPatients receive irinotecan IV over 90 minutes and bevacizumab IV over 10 minutes on days 1 and 15. Patients also receive trifluridine and tipiracil hydrochloride PO BID on days 2-6 and 16-20. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Irinotecan: Given IV Bevacizumab: Given IV Trifluridine and Tipiracil Hydrochloride: Given PO
Median Overall Survival (OS)Medical record review will be performed approximately every 6 months, for up to 2 years, post treatment up to 4 yearsOS will be summarized using standard Kaplan-Meier methods; where estimates of the median survival are obtained with 90% confidence intervals
Disease-specific Survival (DSS)Medical record review will be performed approximately every 6 months, for up to 2 years, post treatment up to 4 yearsDSS will be summarized using standard Kaplan-Meier methods; where estimates of the median survival and 12-month rates are obtained with 90% confidence intervals.
Aggregate Rates of Adverse EventsFollow-up safety evaluations will occur 30 days (± 3 days) after last dose of study drug or until resolution of any drug related toxicity (telephone contact is acceptable), through study completion , an average of 3.5 years workmeasured by Common Terminology Criteria for Adverse Events (CTCAE) v5.0 and recorded to objectively measure toxicities of the combination therapy. Treatment related adverse events (as per CTCAE v5.0) will be summarized by grade using frequencies and relative frequencies. Only grade 4 and 5 adverse events are reported here.
