About this trial

Triple-negative breast cancer (TNBC) is a special subtype of breast cancer that lacks the expression of ER, PR, and Her-2 proteins, accounting for 15%-20% of all breast cancers.TNBC patients do not benefit from endocrine therapy or HER-2-targeted therapy, but are sensitive to cytotoxic drug therapy.Although the survival of TNBC patients has improved significantly compared with the past, it is still the type with the worst prognosis among all subtypes of breast cancer. Methods and drugs to further improve the therapeutic effect of TNBC patients are still being explored.

Camrelizumab, a PD-1 inhibitor produced by Hengrui, has been approved for the treatment of various malignant tumors including advanced lung cancer, advanced liver cancer and advanced esophageal cancer. Shows good therapeutic effect and safety.

Therefore, this study intends to explore the superiority of camrelizumab on the basis of the less toxic anthracycline-free TCb regimen.In order to provide more effective and safe neoadjuvant therapy for lymph node-positive TNBC patients.

Trial outcomes

Primary outcomes

1

Pathological complete response rate (pCR rate)

After neoadjuvant chemotherapy and surgery, the resected specimen (breast + axilla) was free of any invasive cancer (ie, ypT0/is, ypN0)

Time frame
up to 24 weeks

Secondary outcomes

1

Event-Free Survival (EFS)

EFS was defined as the time from randomization to any of the following events: disease progression during neoadjuvant therapy, local or distant recurrence, second primary malignancy (breast or other cancer), or death from any cause.

Time frame
5-10 years after surgery.
2

DFS

Disease-free Survival,From the date of surgery to the first local, regional, contralateral or distant recurrence, and death from any cause

Time frame
5-10 years after surgery
3

Distant Disease Free Survival (DDFS)

DDFS is defined as the time from surgery to distant recurrence or death from any cause

Time frame
5-10 years after surgery
4

Objective Response Rate (ORR)

ORR is defined as the number of target lesion responders as assessed by MRI

Time frame
Preoperative

Other outcomes

1

Expression of PD-L1

Differences in the benefits of carelizumab under different PD-L1 expression status

Time frame
up to 24 weeks
2

gene mutation rate

Predictive value of polygenic analysis in the population benefiting from camrelizumab

Time frame
up to 24 weeks
