Short-course treatment for early HER2-positive breast cancer

Official title: Short-course Trastuzumab, Pertuzumab Combined with Taxanes in the Adjuvant Treatment of Early Human Epidermal Growth Factor Receptor 2-positive Breast Cancer: an Open-label, Single-arm Study

Run by Shanghai Jiao Tong University School of Medicine · NCT05891561 · Data updated 2026-11-12

This study is testing a shorter treatment plan with two medications for early HER2-positive breast cancer to see if it works just as well as the usual year-long treatment but with fewer side effects.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with unilateral primary invasive HER2-positive breast cancer who meet specific clinical criteria.

Probably not a fit

Patients with bilateral or metastatic breast cancer, or those who have received prior treatment, may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This phase II, open-label, single-arm clinical study investigates the effectiveness of a short-course regimen combining trastuzumab and pertuzumab with taxanes for patients with early HER2-positive breast cancer. The goal is to determine if four courses of this dual HER2 blockade can achieve similar outcomes to the standard one-year trastuzumab monotherapy while minimizing adverse effects. Participants will receive the treatment and be monitored for their response and side effects.

Why it matters

Potential benefit: If successful, this approach could provide a more effective and less toxic treatment option for patients with early HER2-positive breast cancer.

How similar studies have gone: While similar approaches have been explored, this specific combination and short-course regimen is relatively novel and has not been extensively tested.
