Summary
This trial is testing a new drug called trastuzumab deruxtecan for patients with advanced breast cancer that hasn't responded to other treatments. The drug works by specifically targeting and killing cancer cells. The study aims to see if this drug helps patients live longer or improves their quality of life compared to other treatments. Trastuzumab deruxtecan has shown significant clinical benefits in treating advanced breast cancer and other similar tumors.
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.
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.
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.

Other Research
HER2-targeted therapies, such as Trastuzumab deruxtecan, are crucial for treating HER2-positive breast cancer. These treatments work by combining a HER2-targeting antibody with a cytotoxic drug, which is delivered directly to cancer cells, thereby inhibiting their growth and minimizing damage to normal cells.
Other similar treatments include Trastuzumab, which blocks HER2 signaling, and Ado-trastuzumab emtansine, another antibody-drug conjugate. These therapies improve treatment efficacy and reduce side effects, offering significant benefits over traditional chemotherapy.
