About this trial

This phase I trial investigates the side effects and best dose of talazoparib when given together with trifluridine/tipiracil for the treatment of patients with colorectal or gastroesophageal cancer that has spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). Drugs used in the chemotherapy, such as trifluridine/tipiracil, 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. Talazoparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving talazoparib with trifluridine/ tipiracil may inhibit certain enzymes in the cells that are responsible for tumor cell growth.

Eligibility criteria

Qualifiers

Histologically or cytologically confirmed CRC or EGC adenocarcinoma that is locally advanced or metastatic (Cohort A); histologically or cytologically confirmed p53mt/RASonc (Cohort B1) or p53mt/RASwt CRC (Cohort B2) that is locally advanced or metastatic. Patients with adenocarcinoma histology only are allowed to participate.

Has received at least one prior line of therapy with progression or intolerance

Have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria present

Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1

Disqualifiers

Systemic antineoplastic therapy within 2 weeks prior to day -14 (Dose Escalation, Cohort A) or Cycle 1 day 1 (Dose Expansion, Cohorts B1 and B2) or within the past 6 weeks if this treatment is mitomycin C or nitrosourea

Radiotherapy within the past 2 weeks excluding palliative radiotherapy to painful bone lesions

Prior treatment with PARP inhibitor, FUDR or FTD/TPI

Any condition that in the investigator's opinion can limit absorption of FTD/TPI or talazoparib from the gastrointestinal (GI) tract
