Recruitment & Eligibility

• Status: RECRUITING
• Sex: Female
• Target Recruitment: 349

Inclusion Criteria

• Signed the informed consent form;

• Women aged ≥ 18 years;

• Patients with locally advanced or metastatic, histologically or cytologically documented breast cancer;

• The primary tumor and metastases (if re-biopsy was performed) were both HER2-negative;

• Eastern Cooperative Oncology Group (ECOG) score [0-1] points;

• Patients must have metastatic disease that is evaluable on imaging: including at least one measurable lesion (assessed according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1)); or only non-measurable disease as defined by RECIST 1.1 , especially in patients with bone metastases only, while the disease could be documented/assessed by bone scan, PET or MRI;

• Previous chemotherapy with taxane for early breast cancer (eBC; neoadjuvant or adjuvant setting) is permitted if completed ≥12 months before randomization;

• No previous chemotherapy for advanced breast cancer ;

• For HR+ breast cancer patients shall meet one of the two criteria below: a) radiographically confirmed recurrence or progression within 2 years of adjuvant endocrine therapy; b) received at least one line of endocrine therapy in the recurrence or metastasis stage;

• Patients must have recovered to ≤ Grade 1 (CTCAE v5.0) from all toxicities related to prior antineoplastic therapy. However, patients with any grade of alopecia were allowed ;

• Patients with asymptomatic CNS metastases may be enrolled, if:

  1. Intracranial lesions are evaluable and eligible for systemic therapy only in the absence of extracranial evaluable lesions, or
  2. Patients with stable intracranial lesions after local treatment while there are extracranial evaluable lesions ;

• Adequate hematological, hepatic and renal function;

• Women of childbearing potential must agree to use a contraceptive method during the treatment period and for at least 90 days after the last dose of experiment treatment;

• Life expectancy of at least 12 weeks;

• Patients must be able to participate and comply with treatment and follow up.

Exclusion Criteria

• HER-2 positive (IHC 3+, or FISH positive);
• Other malignancies (including primary brain or leptomeninges-related tumors) within the past 5 years, except cured cutaneous basal cell carcinoma and cervical carcinoma in situ;
• Patients who have received anti-tumor therapy within 4 weeks prior to the start of study treatment, including chemotherapy, radical radiotherapy, biological therapy, immunotherapy or anti-tumor Chinese medicine therapy;
• Patients who have undergone major organ surgery (excluding needle biopsy) or have significant trauma within 4 weeks before the first dose of treatment, or anticipating for a major surgical procedure during the study;
• Experienced grade ≥ 3 nervous system-related adverse events after treatment with anti-microtubule drugs;
• Symptomatic central nervous system metastases;
• Pregnant or lactating women;
• Known or suspected hypersensitivity to any of the study drugs or excipients;
• Any other non-malignant systemic disease (cardiovascular, renal, hepatic, etc.) that precludes study treatment implementation or follow-up ;
• Any other condition that the investigator considers inappropriate to participate in this trial .
• Use of corticosteroids is prohibited.

Arm && Interventions

Group	Intervention	Description
Arm A	utidelone	utidelone
Arm B	docetaxel	docetaxel

Primary Outcome Measures

Name	Time	Method
Progression Free Survival (PFS)	up to 60 months	Time from randomization to progression or death (whichever occurred first)

Secondary Outcome Measures

Name	Time	Method
Patient-reported health-related quality of life (QoL): FACT-B total score	up to 60 months	Change from baseline in the FACT-B total score for all questionnaire timepoints. To calculate FACT-B total score patient ratings from 0 (not at all) - 4 (very much) to each of the 37 questionnaire statement are summed up. Total score range: 0 - 148. Higher values indicate better quality of life.
Objective response rate (ORR)	up to 60 months	The proportion of patients with a best response of CR or PR, according to RECIST 1.1 criteria
Time to response (TTR)	up to 60 months	the time from randomization to the first documentation of disease response (CR or PR)
Overall survival (OS)	up to 60 months	Time from randomization to death Time from randomization to death Time from randomization to death Time from randomization to death
Duration of response (DOR)	up to 60 months	the time from the first evaluation that criteria for CR or PR are met until PD or death is observed, whichever occurs first, calculated only for patients whose best response is evaluated as CR or PR.
