Vaccine for HER2-positive breast cancer after standard treatment

Breast Cancer

Part of Cancer, Skin clinical trials.

This trial tests a vaccine (GLSI-100) that may help prevent the return of HER2-positive breast cancer. It is given to patients who still had cancer cells after initial treatment with trastuzumab, or who had stage III disease and achieved a complete response.

Summary written for real people, not researchers, by Clin2.

  • You had HER2-positive breast cancer (stages I, II, or III) and completed treatment with trastuzumab (Herceptin) and other standard therapies.
  • You had residual cancer after neoadjuvant therapy, or you had stage III cancer with a complete response.
  • You can start the study vaccine within 1 year after finishing trastuzumab and other treatments.

Studying HER2-positive breast cancer types and features

This study looks at different types of HER2-positive breast cancer to learn more about the disease. It is for people with early-stage or locally advanced breast cancer who have not yet received treatment, and aims to help doctors find better ways to personalize care.

HER2-Positive Breast Cancer Treatment Study Using PET Imaging

This study tests whether using PET scans (a special imaging technique) to monitor how your HER2-positive breast cancer responds to treatment before surgery can help doctors choose the best treatment plan for you. The goal is to improve outcomes by personalizing therapy based on how your tumor responds.

Trastuzumab plus pyrotinib after surgery for HER2 breast cancer

This trial tests whether adding pyrotinib to trastuzumab after surgery can reduce breast cancer coming back in people with HER2-positive, early-stage breast cancer. It may help some patients by improving treatment effectiveness, but it also requires meeting specific heart, lab, and health criteria.

NCT07246317Not yet recruiting· Phase 2
Testing a new drug combo for early HER2+ breast cancer before surgery

This trial tests a combination of targeted therapies (trastuzumab and pertuzumab) with chemotherapy (docetaxel) and an experimental drug (QL1706) given before surgery to shrink early or locally advanced HER2-positive breast cancer. It aims to see if this approach improves outcomes before definitive surgery.
