Detailed Description
PRIMARY OBJECTIVE:
I. To determine the 2-month progression free survival (PFS) rate of tucatinib, trastuzumab, and trifluridine and tipiracil hydrochloride (TAS-102) in patients with HER2 amplified and PIK3CA, RAS, and/or BRAF mutated metastatic colorectal cancer (CRC).
SECONDARY OBJECTIVES:
I. To assess the clinical benefit rate (CBR) (stable disease [SD] for >= 4 months, or best response of complete response [CR] or partial response [PR]) of tucatinib, trastuzumab, and TAS-102 in patients with HER2 amplified and PIK3CA, RAS, and/or BRAF mutated metastatic CRC.
II. To assess the objective response rate (ORR) of tucatinib, trastuzumab, and TAS-102 in patients with HER2 amplified and PIK3CA, RAS, and/or BRAF mutated metastatic CRC.
III. To assess the overall survival (OS) of tucatinib, trastuzumab, and TAS-102 in patients with HER2 amplified and PIK3CA, RAS, and/or BRAF mutated metastatic CRC.
IV. To assess the safety and tolerability of tucatinib, trastuzumab, and TAS-102 in patients with HER2 amplified and PIK3CA, RAS, and/or BRAF mutated metastatic CRC.
CORRELATIVE RESEARCH OBJECTIVES:
I. To assess whether the combination of tucatinib, trastuzumab, and TAS-102 eliminates HER2 amplified circulating tumor deoxyribonucleic acid (DNA) (ctDNA) from peripheral blood.
II. To explore the correlation between tissue and blood-based biomarkers and clinical outcomes.
OUTLINE:
Patients receive tucatinib orally (PO) twice daily (BID), trastuzumab intravenously (IV) over 30-90 minutes on days 1 and 15, and TAS-102 PO BID on days 1-5 and 8-12. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up within 30 days and then every 12 weeks for 4 years after study enrollment.
