Study Summary

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).

Primary Outcome

A renal DLT was defined as an increase in serum cystatin C \>1.5\* baseline that was not related to pre-renal or post-renal etiologies (including disease progression, dehydration and intercurrent illness) and occurred during the period of treatment with tucatinib in combination with trastuzumab and FOLFOX between the first dose of tucatinib and the end of Cycle 3. Increased serum cystatin C for which there was an alternative clinical explanation (eg, clearly related to an intercurrent illness or
