T-DXd for breast cancer: comparing drug levels by BMI
Part of Cancer, Skin clinical trials.
This trial studies how the drug T-DXd (trastuzumab-deruxtecan) works in people with advanced or metastatic breast cancer. It compares drug levels in the body based on body mass index (BMI) to see if dose adjustments are needed.
Summary written for real people, not researchers, by Clin2.

- Your doctor says T-DXd is right for you.

This study follows women with advanced breast cancer (metastatic) who have hormone-receptor positive tumors and low HER2 levels, to see how well a new drug called Trastuzumab Deruxtecan works when used in routine clinical care after prior hormone therapy.
This trial uses a blood test to look for tumor DNA in women with a certain type of advanced breast cancer (HR-positive, HER2-low). If the DNA doesn't disappear after starting standard hormone therapy with a CDK4/6 inhibitor, participants may be switched to a targeted drug called T-DXd (trastuzumab deruxtecan).
This study tests a drug called T-DXd (trastuzumab deruxtecan) for people with advanced breast cancer that has very low levels of HER2 (a protein that helps cancer grow) and that is also hormone receptor positive. The goal is to see if this drug can help shrink or slow the cancer.
This trial compares two treatments for advanced breast cancer that is HR-positive, HER2-low or ultralow, and a non-luminal subtype. It tests if a targeted antibody-drug conjugate (T-DXd) works better than the usual first-line therapy combining a CDK4/6 inhibitor with hormone therapy. This study is for people who have not had any treatment for advanced disease.
This study looks at how well Trastuzumab Deruxtecan (T-DXd) works in Chinese women with breast cancer that has spread. It is for people whose cancer is either HER2-positive or HER2-low and who have already had some treatment.
This study looks at how well the drug T-DXd (Enhertu) works against breast cancer that has spread or can't be removed with surgery. It includes patients with any level of HER2 protein, so it might be an option even if your cancer has low HER2.
