Trastuzumab plus pertuzumab for HER2-mutated cancers
This trial tests whether combining trastuzumab and pertuzumab can treat cancers that have HER2 amplification or an activating HER2 mutation. It looks at people ages 12 and older, and may include both children/teens and adults, using the study drug based on their HER2 test results.
BelfastAges 12 years+ - NCT05800275RecruitingPhase 2
Tucatinib and capecitabine plus spinal trastuzumab for HER2+ cancer
This Phase 2 trial tests a combination of tucatinib and capecitabine (taken by mouth) plus trastuzumab delivered into the spinal fluid, to treat breast cancer that has spread to the leptomeninges (lining around the brain/spinal cord). It may help reduce cancer activity in the spinal fluid and improve symptoms.
