Colon Cancer Clinical Trial
TAS-102 and Oxaliplatin for the Treatment of Refractory Stage IV Colon Cancer
This phase II trial studies how well TAS-102 and oxaliplatin work in treating patients with stage IV colon cancer. Drugs used in chemotherapy, such as TAS-102 and oxaliplatin, 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.
I. Overall response rate (ORR).
I. Progression free survival (PFS). II. Overall survival (OS). III. Disease control rate (DCR). IV. Duration of response. V. Safety and tolerability.
Patients receive trifluridine and tipiracil hydrochloride (TAS-102) orally (PO) twice daily (BID) on days 1-5 and oxaliplatin intravenously (IV) over 2 hours on day 1. Cycles repeat every 14 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 28 days.
Histologically confirmed stage IV colon cancer (American Joint Committee on Cancer [AJCC] 7th edition) that has progressed after standard therapy that included fluorouracil (5-FU), irinotecan, oxaliplatin, bevacizumab (unless contraindicated) and an anti-EGFR antibody, if RAS wild type. Patients who could not tolerate standard agents because of unacceptable, but reversible toxicity necessitating their discontinuation will be allowed to participate
Patients who had received adjuvant chemotherapy and had recurrence during or within 6 months of completion of the adjuvant chemotherapy will be allowed to count the adjuvant therapy as one chemotherapy regimen
Progression of disease must be documented on the most recent scan
Presence of measurable disease
RAS mutation and mismatch repair deficiency (MMR) status must be determined (or tissue availability for testing if not already determined)
Eastern Cooperative Oncology Group (ECOG) performance status 0-1
Life expectancy of at least 3 months
Absolute neutrophil count (ANC) >= 1.5 x 10^9/L
Hemoglobin >= 9 g/dL
Platelets (PLT) >= 75 x 10^9/L
Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 5 x upper limit of normal (ULN)
Adequate contraception if applicable
Women who are nursing and discontinue nursing prior to enrollment in the program
Ability to take oral medication (i.e., no feeding tube)
Patient able and willing to comply with study procedures as per protocol
Patient able to understand and willing to sign and date the written voluntary informed consent form (ICF) at screening visit prior to any protocol-specific procedures
Patients who have previously received TAS-102
Grade 2 or higher peripheral neuropathy (functional impairment)
Symptomatic central nervous system (CNS) metastases requiring treatment
Other active malignancy within the last 3 years (except for non-melanoma skin cancer or a non-invasive/in situ cancer)
Pregnancy or breast feeding
Current therapy with other investigational agents
Active infection with body temperature >= 38 degree Celsius (C) due to infection

Any anticancer therapy within prior 3 weeks of first dose of study drug
History of allergic reactions attributed to compounds of similar chemical or biologic composition to TAS-102
Current therapy with other investigational agents or participation in another clinical study or any investigational agent received within prior 4 weeks
Grade 3 or higher hypersensitivity reaction to oxaliplatin, or grade 1-2 hypersensitivity reaction to oxaliplatin not controlled with pre-medication
Has unresolved toxicity of greater than or equal to Common Terminology Criteria for Adverse (CTCAE) grade 2 attributed to any prior therapies (excluding anemia, alopecia, skin pigmentation, and platinum-induced neurotoxicity)
