DB-06 Trial Summary
This trial will compare the effectiveness of a new drug, trastuzumab deruxtecan, with standard chemotherapy in treating HER2-low, hormone receptor-positive breast cancer that has progressed despite endocrine therapy.
Who is the study for?
This trial is for adults over 18 with advanced or metastatic breast cancer that has low HER2 expression and progressed after endocrine therapy. Participants must not have had prior chemotherapy for their advanced cancer, should have adequate organ function, and provide tumor samples to confirm HER2 status. Those with significant lung disease, uncontrolled heart conditions, active infections, or a history of certain lung problems are excluded.Check my eligibility
What is being tested?
The study compares the effectiveness of Trastuzumab Deruxtecan (T-DXd) against standard chemotherapies like Capecitabine and Paclitaxel in patients with specific types of breast cancer. It aims to see which treatment is better at controlling the disease while monitoring safety and tolerability.See study design
What are the potential side effects?
Trastuzumab Deruxtecan can cause side effects such as fatigue, nausea, hair loss, decreased blood cell counts increasing infection risk, potential heart damage or interstitial lung disease. Standard chemotherapies may also lead to similar side effects including nerve damage from Paclitaxel.
