Study Summary

This trial is for people with solid tumors that make too much HER2 or a different type of HER2. Participants will get tucatinib and trastuzumab. People with hormone-receptor positive breast cancer will also get fulvestrant. The trial will look at side effects.

Who is the study for?
This trial is for adults with advanced solid tumors that have HER2 alterations and have worsened after treatment, or can't be surgically removed. They must have an ECOG performance status of 0 or 1 (fully active or restricted in physically strenuous activity but ambulatory), measurable disease, and specific types of non-small cell lung cancer (NSCLC). Those with certain breast cancers are excluded, as well as anyone previously treated with HER2-targeted therapy unless specified.Check my eligibility
What is being tested?
The study tests the effectiveness of tucatinib combined with trastuzumab on various solid tumors with abnormal HER2 production. Patients with hormone-receptor positive breast cancer will also receive fulvestrant. The goal is to see how these drugs work together against different tumor types that are either metastatic or unresectable.See study design
What are the potential side effects?
Potential side effects include reactions related to drug infusion, allergic responses to ingredients in the medications, heart issues due to past treatments like anthracyclines, and general side effects such as fatigue, nausea, diarrhea which commonly occur during cancer therapies.
