Clinical Trial Summary

This study is to evaluate the efficacy and safety of combination of Camrelizumab (Immunotherapy, PD-1 inhibitor), Fluzoparib (PARP inhibitor) and Nab-paclitaxel in neoadjuvant therapy of Her-2 negative breast cancer patients with HRR gene mutation.

Description:

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.

Pathologic complete response is defined as no invasive cancer in the resected breast tissue and lymph nodes (ypT0/Tis, ypN0).	Up to 32 weeks
Secondary	Objective Response Rate (ORR)	ORR is defined as percentage of participants with Complete Response and Partial Response	Up to 32 weeks
Secondary	Residual Cancer Burden (RCB)	Pathologilly assessed residual cancer burden according to MD Anderson protocol.	Up to 32 weeks
Secondary	Event-Free Survival (EFS)	EFS was defined as the time from the date of randomization to the date of events from any cause.	Up to 20 years
Secondary	Overall Survival (OS)	OS was defined as the time from the date of randomization to the date of death from any cause.	Up to 20 years
Secondary	Safety of drugs	Adverse effects of the candidates according to NCI-CTCAE 5.0	Up to 32 weeks
