Detailed description: This study was a multicenter, randomized, open, single-dose, two-cycle, two-cross-dosing human bioequivalence trial designed to evaluate the bioequivalence of tested and reference preparations in breast cancer subjects.

Eligibility criteria: Inclusion Criteria:

1. Subjects voluntarily participate in the study and sign the informed consent forms (ICFs);
2. Patients with breast cancer confirmed by histopathology and/or cytology who meet one of the following conditions: ① with metastatic breast cancer that does not respond to combination chemotherapy or recurrent breast cancer within 6 months after adjuvant chemotherapy, and an anthracycline anticancer drug should be used in the previous chemotherapy unless clinically contraindicated; ② investigators determine that subjects are candidates for albumin-bound paclitaxel by reference to the treatment guidelines (NCCN Guidelines and CSCO Guidelines for breast cancer);
3. Aged 18-75 years old (both inclusive), males or females; body mass index (BMI) ≥17 (BMI = weight (kg)/height (m2));
4. The ECOG score is 0-2;
5. The expected survival time is ≥3 months;
6. Subjects have no plans to become pregnant and voluntarily use non-pharmacologic contraception (such as total abstinence, condom, contraceptive ring, vasectomy, etc.) or other highly effective contraceptive methods, and have no plans to donate eggs or sperm throughout the trial and within 6 months after the last dose;
7. Subjects with the laboratory test results as follows: hemoglobin (Hb) ≥80 g/L (no blood transfusion within 14 days), absolute neutrophil count (ANC) ≥1.5 \* 109/L, platelet count (PLT) ≥100 \* 109/L; alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3 times the upper limit of normal value (for patients without liver metastasis) or ≤5 times the upper limit of normal value (for patients with liver metastasis); total bilirubin (TBIL) ≤1.5 times the upper limit of normal value (for patients without liver metastasis) or ≤3 times the upper limit of normal value (for patients with liver metastasis); serum creatinine clearance ≥60 mL/min \[formula: Ccr: (140 - age) \* body weight (kg) \* 0.85 (if female)/0.818 \* Scr (μmol/L)\]; international normalized ratio (INR) ≤1.5 times the upper limit of normal value;
8. Subjects are able to communicate well with the investigator and understand and comply with the requirements of the study.

Exclusion Criteria:

1. Subjects with allergic constitution (excluding mild asymptomatic seasonal allergies), or who are known (or suspected) to be allergic to or have a specific reaction to the active ingredient paclitaxel or excipients, albumin;
2. Subjects who have received radiotherapy, chemotherapy, immunotherapy and endocrinotherapy within 4 weeks before the administration of the investigational drug and still respond to the treatment;
3. Subjects who have suffered from serious illness of cardio-cerebral vascular system, lung, liver, kidney, gastrointestinal tract, endocrine system, immune system, skin, musculoskeletal system and nervous system or psychiatric disorders within 3 months before screening and are considered unsuitable for enrollment by the investigator;
4. Subjects who have undergone major surgery or suffered from fracture within 4 weeks prior to screening, or plan to undergo major surgery during the study;
5. Subjects who have received treatment with other investigational drugs within 4 weeks before the study;
6. Subjects who have used substrates, inducers or inhibitors of CYP2C8 or CYP3A4 enzymes (including but not limited to ketoconazole and other imidazole antifungal agents, verapamil, diazepam, quinidine, dexamethasone, cyclosporine, teniposide, etoposide, vincristine, testosterone, 17-α diethylstilbestrol, retinoic acid, quercetin, erythromycin, fluoxetine, gemfibrozil, cimetidine, ritonavir, saquinavir, indinavir, nelfinavir, rifampicin, carbamazepine, phenytoin, efavirenz, nevirapine, etc.) in concomitant medications within 4 weeks prior to the first dose of the investigational drug or fail to suspend medications during the study (except for stable dosing at steady state, i.e. the dosing regimen remains unchanged);
7. Subjects who have consumed special diet (foods that affect the activity of CYP3A4 or CYP2C8 enzyme, such as grapefruit, pomelo, mango, etc.), exercised vigorously or with other factors that may affect drug absorption, distribution, metabolism and excretion within 48 hours before the administration of the investigational drug;
8. Subjects who have received therapy with the granulocyte colony-stimulating factor (G-CSF) within 2 weeks before screening;
9. Subjects with grade 2 or higher sensory neuropathy/peripheral neuropathy at screening;
