HER2CLIMB-05 Trial Summary

This trial is testing to see if adding tucatinib to trastuzumab and pertuzumab will help people with HER2-positive breast cancer live longer without their disease getting worse.

Who is the study for?
This trial is for individuals with HER2-positive breast cancer that's locally advanced, unresectable, or metastatic. Participants should have received specific induction therapy without disease progression and can't be undergoing certain treatments or have poorly controlled seizures. They must not need immediate treatment for brain metastases and should not have symptomatic brain lesions posing risk.Check my eligibility
What is being tested?
The study tests if tucatinib plus trastuzumab and pertuzumab is more effective than a placebo combined with the same drugs in treating HER2-positive breast cancer. It's randomized and blinded, meaning participants won't know if they're receiving tucatinib or a placebo.See study design
What are the potential side effects?
Potential side effects include reactions to the drug combination such as fatigue, nausea, allergic responses, potential heart issues due to trastuzumab and pertuzumab, as well as any unforeseen effects of tucatinib since it's being tested.
