Read Full Scientific Objectives & Methods
This is a prospective, single-center, open-label phase II clinical trial investigating the activity of Camrelizumab+Fluzoparib+Nab-paclitaxel combination therapy in breast cancer patients with Her2-negative and HRR gene mutation for neoadjuvant therapy. Anticipated 66 candidates meeting all study eligibility criteria will receive 8 cycles of Nab-paclitaxel (260mg/m2) every 3 weeks, which will add Camrelizumab (200mg, d1) and Fluzoparib (100mg BID) from the second cycle. HRR gene mutation contains at least one pathogenic or likely pathogenic variant in germline or somatic BRCA1, BCRA2 and PALB2 genes, or in germline ATM, BARD1, BRIP1, CDK12, CHEK2, RAD51C, RAD51D genes.
Camrelizumab at a fixed dose of 200mg via IV infusion on Days 1 each 21-day cycle. Fluzoparibat at a fixed dose of 100mg BID, each 21-day cycle. Nab-paclitaxel at a fixed dose of 260 milligrams via intravenous (IV) infusion on Days 1 each 21-day cycle.

Nab-paclitaxel
Treatment Arms Description
Participants who confirmed pathogenic or likely pathogenic HRR gene mutation received Camrelizumab and Fluzoparib with nab-paclitaxel from the second cycle followed by nab-paclitaxel for one cycle.

Primary Outcome Measures
- Pathologic Complete Response (pCR) — Time Frame: Up to 32 weeks
Pathologic response will be assessed in the surgically resected cancer and lymph nodes after completion of all chemotherapy by the local pathologist as part of routine care. Pathologic complete response is defined as no invasive cancer in the resected breast tissue and lymph nodes (ypT0/Tis, ypN0).
View Secondary Outcome Measures (5)
- Objective Response Rate (ORR) — Time Frame: Up to 32 weeks
ORR is defined as percentage of participants with Complete Response and Partial Response
- Residual Cancer Burden (RCB) — Time Frame: Up to 32 weeks
Pathologilly assessed residual cancer burden according to MD Anderson protocol.
- Event-Free Survival (EFS) — Time Frame: Up to 20 years
EFS was defined as the time from the date of randomization to the date of events from any cause.
- Overall Survival (OS) — Time Frame: Up to 20 years
OS was defined as the time from the date of randomization to the date of death from any cause.
- Safety of drugs — Time Frame: Up to 32 weeks
