Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single-arm, open-label, multicenter, phase II study to evaluate the efficacy and safety of SG001 in combination with Nab-paclitaxel in patients with advanced TNBC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a single-arm, open label, multicenter phase II study to evaluate the efficacy and safety of SG001 in combination with nab-paclitaxel in patients with unresectable locally advanced, or recurrent, or metastatic TNBC. Eligible patients will receive SG001 intravenous infusion at a dose of 240 mg on Days 1 and 15 of every 4-week cycle and nab-paclitaxel intravenous infusion at a dose of 100 mg/m\^2 on Days 1, 8, and 15 of every 4-week cycle until disease progression, or intolerable toxicity, or other discontinuation or termination criteria are met, for a maximum of 2 years.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Female patients, aged 18-70 years (inclusive), voluntarily join the study and sign the informed consent form.
2. Eastern Cooperative Oncology Group (ECOG) (ECOG): 0 \~ 1 point;
3. Histologically confirmed TNBC, namely, human epidermal growth receptor 2-negative (HER2-negative) and estrogen receptor-negative (ER-negative) and progesterone receptor-negative (PR-negative); Patients with confirmed TNBC metastatic lesions are eligible.
4. Patients with locally advanced (staging according to AJCC 8th Edition) inoperable or recurrent/metastatic TNBC who have received ≤ 1-line system treatment. The number of treatment-naïve patients and the pre-treated patients should be approximately in equal numbers. The interval ≥ 6 months between the end of taxane-based adjuvant/neoadjuvant therapy and the occurrence of recurrence/metastasis, and an interval ≥ 3 months between the end of taxane-based therapy for advanced breast cancer and the occurrence of recurrence/metastasis.
5. Provide archived tissue for detecting the expression level of PD-L1, or if not available, agree to perform a tumor tissue biopsy for PD-L1 detection during the screening period.

1. The proportion of patients with CPS ≥ 10 should be ≥ 20% and ≤ 50% of all patients;
2. The archived tissue must be representative of the latest tumor specimen, and the relevant pathological reports of the above specimens must also be provided;
3. Fresh tissue specimens can be obtained by surgical resection and biopsy; Fine needle aspiration and liquid based cytology (TCT) samples are not accepted (i.e. samples lacking complete tissue structure and providing only cell suspension and/or cell smear);
4. For patients with negative PD-L1 in the initially archived tumor tissue samples, biopsy can be performed during screening period to redetect the expression status of PD-L1 with the consent of the patients, and a positive tumor tissue sample of any kind is considered PD-L1 positive (i.e. CPS ≥ 1);
6. At least one measurable lesion confirmed by CT or MRI at baseline as per the solid tumor efficacy evaluation criteria (RECIST v1.1). The measurable lesions should not have received local treatment such as radiotherapy (lesions located in the previous radiotherapy area can also be selected as target lesions if progression is confirmed);
7. Estimated survival time ≥ 12 weeks;
8. Adequate organ function, defined by the following laboratory results obtained within 14 days prior to the enrollment::

1. Blood routine (no blood transfusion within 14 days before the first administration, no hematopoietic stimulating factor and no other drugs to correct the number of blood cells): neutrophil count (ANC) ≥ 1.5 × 109/L; Platelet count (PLT) ≥ 75 × 109/L; Hemoglobin (HGB) ≥ 9 g/dL;
2. Blood biochemistry: serum creatinine (Cr) ≤ 1.5 × ULN or creatinine clearance (CCR) ≥ 50 mL/min; Total bilirubin (TBIL) ≤ 1.5 × ULN (≤ 3 × ULN for patients with Gilbert's syndrome); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 × ULN (≤ 5 × ULN for patients with hepatocellular carcinoma or liver metastasis);
3. Coagulation function: activated partial thromboplastin time (APTT) and international standardized ratio (INR) ≤ 1.5 × ULN (not corrected with anticoagulants or other drugs affecting coagulation function within 14 days before the first dose, except for the long-term use of anticoagulants due to the patient's disease);
