A Study of TQB2450 Injection and Anlotinib Hydrochloride Capsules to Treat Triple Negative Breast Cancer (TNBC)

This is an interventional treatment trial for Triple Negative Breast Cancer (TNBC) Read More

Inclusion Criteria:

- 1、18 and 75 years old; ECOG physical condition: 0 - 1 points; expected survival time more than 3 months。 2、Histological or cytological diagnosis of relapsed/metastatic triple receptor negative breast cancer (TNBC).TNBC is defined negatively expression of estrogen(ER), progesterone(PR) and human epidermal receptor-2(HER2).If there is a pathology report of the metastasis, take the histopathology of the metastases as standard. Negative of ER and PR is defined as expression of ER,PR<1% of the tumor cells by immunohistochemistry (IHC). HER2-negative is defined as a score of 0 and 1+ by IHC, or IHC 2+ & fluorescent in situ hybridization (FISH)negative. If the ER2 test result is 0 or 1+ by IHC, FISH detection is optional, but the result must be negative.

3、Patients had at least one measurable lesion (RECIST 1.1); 4、Participants has received prior anthracyclines and/or taxanes in first-line therapy. Disease progressed after latest chemotherapy. For adjuvant therapy/neoadjuvant therapy, disease relapse or progression during treatment or within 6 months after treatment is considered as failure of standard therapy.

7. Uncontrolled pleural effusion, pericardial effusion or ascites requiring repeated drainage；
8.

9. Patients have uncontrollable symptoms of brain metastasis, spinal cord compression, cancerous meningitis, or diseases found in CT or MRI during screening within 8 weeks before the first administration;
10. four weeks before the start of study treatment has been approved or in the research of anti-tumor treatment, including but not limited to, surgery, radiation therapy, chemotherapy, biological target therapy, interventional therapy, immune therapy and anti-tumor Chinese medicine therapy (to be based on the instroction of Chinese traditional medicine, after 2 weeks elution phase can also be set)and so on (note: people who oral targeted drug is less than five drugs half-life;Or oral fluorouracil drugs less than 14 days, mitomycin C and nitroso urea less than 6 weeks;Patients with adverse events (except hair loss) caused by previous treatment did not recover to a level less than or less than CTCAE 1；
