This is a phase I clinical trial assessing the safety and recommended phase II dose of cabozantinib in combination with trifluridine/tipiracil (TAS102) in patients with metastatic colorectal carcinoma (mCRC).

Official Title

A Phase 1 Study of the Combination of Cabozantinib With Trifluridine/Tipiracil (TAS-102) in Patients With Metastatic Colorectal Adenocarcinoma (mCRC)


Patients with histologically proven colorectal adenocarcinoma not amenable to curative treatment will be eligible to participate for this study. After meeting the eligibility criteria, patients will be given a IP regimen consisting of cabozantinib 20 - 40 mg given orally everyday for 28 days, trifluridine/tipiracil (TAS102) 25 - 35 mg/m2 on Days 1 - 5 and Days 8 - 12 every 28 days, and peg-filgrastim 6 mg subcutaneously on Day 13 every 28 days. Tumor assessments will be completed by CT/MRI every 8 weeks during the first year of treatment and every 3 months after the first year until patient comes off treatment.

  • The effects of cabozantinib on the developing human fetus at the recommended therapeutic dose are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 4 months following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

Subjects with a diagnosis of incidental, subsegmental PE or DVT within 6 months are allowed if stable, asymptomatic, and treated with a stable dose of permitted anticoagulation (see exclusion criterion #3.2.8) for at least 1 week before first dose of study treatment.
    3. Gastrointestinal (GI) disorders including those associated with a high risk of perforation or fistula formation:The subject has evidence of tumor invading the GI tract, active peptic ulcer disease, inflammatory bowel disease (e.g., Crohn's disease), diverticulitis, cholecystitis, symptomatic cholangitis or appendicitis, acute pancreatitis, acute obstruction of the pancreatic duct or common bile duct, or gastric outlet obstruction.
