Combining Serplulimab with Chemotherapy for Early-stage HR+/HER2- Breast Cancer

Official title: Neoadjuvant NabPE With or Without Serplulimab for Early-stage Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative (HR+/HER2-) Breast cancer-an Observational Real-world Study.

Run by Henan Cancer Hospital · NCT06781281 · Data updated 2026-11-12

This study is testing if adding a new drug called serplulimab to standard chemotherapy helps people with early-stage HR+/HER2- breast cancer have better outcomes before surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with pathologically confirmed HR+/HER2- breast cancer and measurable lesions.

Probably not a fit

Patients with metastatic breast cancer or those who have previously received treatment for this disease 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 clinical study aims to evaluate the effectiveness of serplulimab in combination with neoadjuvant chemotherapy for patients with early-stage HR+/HER2- breast cancer. Participants will receive serplulimab along with nab-paclitaxel and epirubicin every three weeks for six cycles, followed by surgery. The primary endpoint is to assess the pathological complete response (pCR) rate at the time of definitive surgery, comparing results to existing literature on chemotherapy alone. The study also seeks to identify any medical issues participants may experience while receiving serplulimab.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes for patients with early-stage HR+/HER2- breast cancer by increasing the pCR rate.

How similar studies have gone: Previous studies have shown promising results with similar immunotherapy approaches in breast cancer, indicating potential for success in this trial.
