What this trial studies

This clinical trial evaluates the efficacy and safety of a combination therapy involving Camrelizumab, Fluzoparib, and Nab-paclitaxel for neoadjuvant treatment in patients with Her-2 negative breast cancer and HRR gene mutations. The study is a prospective, single-center, open-label phase II trial that aims to enroll 66 eligible candidates. Participants will receive 8 cycles of Nab-paclitaxel, with the addition of Camrelizumab and Fluzoparib starting from the second cycle. The focus is on patients with specific pathogenic mutations in genes related to homologous recombination repair.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients with early-stage breast cancer who have HRR gene mutations.

How similar studies have gone: Other studies have shown promise with similar combination therapies in treating breast cancer, indicating potential for success in this approach.
