Study of ctDNA Guided Change in Tx for Refractory Minimal Residual Disease in Colon Adenocarcinomas

Summary

This is a phase 1b, prospective, single arm, non-randomized, open-label clinical trial determining the efficacy of adjuvant trifluridine and tipiracil (TAS-102) in combination with irinotecan in patients with ctDNA positive colon adenocarcinoma.

Eligibility Criteria

Inclusion Criteria:

Patients must have histologically or cytologically confirmed adenocarcinoma of the colon (high rectal cancer is eligible if resected and no radiation needed). Other histologies which are treated per NCCN guidelines for adjuvant colon cancer are eligible.
Must have Stage II, Stage III, or Stage IV colorectal cancer after curative intent resection eligible for adjuvant doublet chemotherapy for at least 3 months.
Must have ctDNA positive assay (tested by Signatera MRD assay) after at least 3 months of perioperative chemotherapy
Age ≥ 18 years
Performance status: ECOG performance status ≤2
Life expectancy of greater than 3 months

Adequate organ and marrow function as defined below:

leukocytesL ≥ 3,000/mcL
absolute neutrophil count: ≥ 1,500/mcL
platelets: ≥ 80,000/mcl
total bilirubin: within normal institutional limits
AST(SGOT)/ALT(SPGT): ≤ 3 X institutional upper limit of normal or ≤ 5 X if liver metastases are present
creatinine: <1.5 X ULN

The effects of TAS-102 on the developing human fetus at the recommended therapeutic dose are unknown. For this reason and because topoisomerase inhibitors are known to be teratogenic, 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 90 days 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.

a. A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

Has not undergone a hysterectomy or bilateral oophorectomy; or
Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).
Ability to swallow tablets
Ability to understand and the willingness to sign a written informed consent.

Exclusion Criteria:

Patients who have had major surgery within 4 weeks, or chemotherapy or radiotherapy within 2 weeks prior to Cycle 1 Day 1
All toxicities attributed to prior anti-cancer therapy other than alopecia must have resolved to grade 1 or baseline
Patients may not be receiving any other investigational agents.
Patients with known metastases.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to TAS-102, irinotecan or other agents used in study.
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Prior treatment with irinotecan or TAS-102.
History of another primary cancer within the last 3 years with the exception of non-melanoma skin cancer, early-stage prostate cancer, or curatively treated cervical carcinoma in-situ.
Inability to comply with study and follow-up procedures as judged by the Investigator
Patients who are pregnant or nursing due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants. -
