Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response

Anatomic Stage I Breast Cancer AJCC v8Anatomic Stage II Breast Cancer AJCC v8Early Stage HER2+ Breast Cancer

Treatments studied

Part of Cancer clinical trials.

This trial compares 6 months versus 12 months of HER2-targeted therapy for people with HER2+ breast cancer who had a complete response after chemo and trastuzumab. The goal is to see if a shorter treatment is just as effective.

Who can take part

  • You had HER2+ breast cancer that was stage T1c-T3 and N0-N1 (except T3N1) before treatment.
  • After chemotherapy and trastuzumab, there was no cancer left in the breast or lymph nodes (except for a type of non-invasive cell called DCIS).
  • You received at least 12 weeks of trastuzumab with chemotherapy before surgery.
  • You are 18 years or older and have a good general health status (ECOG 0-2).
  • You had surgery to remove all visible cancer, and you either had a mastectomy or lumpectomy with clear margins.
  • You are registering within 14 weeks of your final surgery.

NCT07407920Recruiting· Phase 2
Optimizing treatment for early HER2+ and triple-negative breast cancer

This trial aims to see if patients who had a complete response to chemo before surgery can safely stop or reduce their targeted therapy afterward. It includes people with early-stage HER2-positive or triple-negative breast cancer who had no cancer cells left in the tissue removed at surgery (a pathological complete response).

NCT05891561Recruiting· Phase 2
Short antibody treatment after surgery for early HER2+ breast cancer

This Phase 2 study tests a shorter schedule of trastuzumab and pertuzumab combined with chemotherapy (taxanes) to reduce breast cancer coming back after surgery. It mainly helps people with early-stage, HER2-positive breast cancer that has not spread, by testing whether a shorter plan still works well and is tolerable.

Optimizing treatment before surgery for HER2-positive breast cancer

This trial tests a neoadjuvant (before surgery) treatment plan for people with early-stage HER2-positive breast cancer. The goal is to see if a personalized approach can improve outcomes.

NCT04993014Recruiting· Phase 2
De-escalating treatment after HER2-positive breast cancer responds

This study looks at whether some people with HER2-positive breast cancer can safely receive less (de-escalated) treatment after they finish chemotherapy plus HER2-targeted drugs before surgery. It specifically focuses on people whose cancer shows a complete response on the surgery pathology report.

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.

NCT07540520Not yet recruiting
Follow-up study of HER2-positive breast cancer after pre-surgery treatment

This study follows patients with HER2-positive breast cancer who received chemotherapy and a targeted drug (trastuzumab) before surgery but did not have a complete response. Researchers want to understand which follow-up treatments work best to prevent cancer from coming back.
