New drug vs. T-DM1 for HER2-positive advanced breast cancer
Treatments studied
Part of Cancer clinical trials.
This trial tests a new antibody-drug conjugate (DP303c) against an existing one, T-DM1, in people with HER2-positive advanced breast cancer who have already been treated with trastuzumab and a taxane. The goal is to see if the new drug works better or has fewer side effects.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have HER2-positive breast cancer that has spread to nearby areas or to other parts of the body and cannot be removed by surgery.
- You must have already received treatment for advanced breast cancer with trastuzumab (Herceptin) and a taxane chemotherapy (like paclitaxel or docetaxel).
- You must be at least 18 years old and willing to use effective birth control during the study.
- You should not have taken any other antibody-drug conjugate (ADC) that targets HER2 and contains a tubulin inhibitor (like T-DM1) before.
- You cannot have untreated or growing brain metastases, or other cancers in the last 3 years.
- Your overall health should be fairly good (ECOG score 0–2, meaning you are up and about most of the day).

This trial compares a new drug, GQ1005, with an existing treatment called T-DM1 for people with HER2-positive breast cancer that has spread or cannot be removed by surgery. The goal is to see which one works better for those who have already received certain other treatments.
This trial tests whether a new drug called BL-M07D1 works better than an existing drug, T-DM1, for people with HER2-positive breast cancer who still have cancer cells after initial treatment (neoadjuvant therapy). The goal is to prevent the cancer from coming back.
This trial tests a new antibody-drug combination (trastuzumab rezetecan, also called T-DXd) for patients with HER2-positive breast cancer whose tumor did not fully disappear after initial chemotherapy. The goal is to see if this drug can reduce the risk of cancer coming back.
This clinical trial tests a combination of two targeted therapies for people with HER2-positive breast cancer that has spread or come back. The goal is to see if adding ribociclib to T-DM1 is safe and effective after other treatments have been used.
This trial tests a new medicine that targets cancer cells with specific proteins, to see if it can stop the growth of advanced pancreatic and breast cancer when other treatments have stopped working. It is an umbrella study, which means different protein-matched drugs are tested for different cancer types.
This trial compares a new targeted therapy (JSKN003) against Kadcyla (T-DM1) for people with HER2-positive breast cancer that has advanced or spread. Both drugs work by attaching a chemotherapy directly to HER2-positive cancer cells, and the study aims to see if the new drug works better or has fewer side effects.
