Tucatinib Plus Trastuzumab and Oxaliplatin-based Chemotherapy or Pembrolizumab-containing Combinations for HER2+ Gastrointestinal Cancers
Sponsor: Seagen, a wholly owned subsidiary of Pfizer
ClinicalTrials ID:NCT04430738
This trial evaluates the safety and efficacy of tucatinib with trastuzumab and other drugs in HER2+ gastrointestinal cancers. Eligible participants have unresectable or metastatic HER2+ tumors and are candidates for oxaliplatin-based regimens. Interventions include tucatinib, trastuzumab, oxaliplatin, leucovorin, fluorouracil, capecitabine, and pembrolizumab, administered in specified doses and schedules.

Program Overview
This trial studies tucatinib to find out if it is safe when given with trastuzumab and other anti-cancer drugs (pembrolizumab, FOLFOX, and CAPOX). It will look at what side effects happen when participants take this combination of drugs. A side effect is anything the drug does other than treating cancer. It will also look at whether tucatinib works with these drugs to treat certain types of cancer.
The participants in this trial have HER2-positive (HER2+) cancer in their gut, stomach, intestines, or gallbladder (gastrointestinal cancer).
