Utidelone Plus Capecitabine Versus Taxane Plus Capecitabine in HER2-negative Locally Advanced or Metastatic Breast Cancer

Utidelone Plus Capecitabine Versus Taxane Plus Capecitabine in HER2-negative Locally Advanced or Metastatic Breast Cancer : A Phase III, Open-label, Randomized Controlled Trial

It is a phase III trial to explore the efficacy and safety of utidelone plus capecitabine versus taxane plus capecitabine in HER2-negative locally advanced or metastatic breast cancer and the differences of metronomic capecitabine and intermittent capecitabine in combination chemotherapy.

Description

Inclusion Criteria:

• Signed 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 aspirated) are both HER2-negative;
• Eastern Cooperative Oncology Group (ECOG) score [0-2] points;
• Measurable disease according to RECIST version 1.1;
• Previous chemotherapy with taxane for early breast cancer (eBC; neoadjuvant or adjuvant setting) is permitted if completed ≥12 months before randomisation;
• No more than one prior chemotherapy regimen for inoperable locally advanced or metastatic HER2-negative breast cancer;
• Hormone receptor positive patients are allowed no more than two lines of prior endocrine therapy for metastatic disease (including CDK4/6 inhibitors, chidamide and PI3K inhibitors, etc.);
• 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 are allowed ;

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

  2. Patients with stable intracranial lesions after local treatment while there are extracranial evaluable lesions ;
• Adequate hematological, hepatic and renal function;
• Women of child bearing 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 + + +, 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, hormone therapy, 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;
• Symptomatic peripheral neuropathy or CTCAE 5.0 grade ≥ 2;
• Experienced grade 3 or above nervous system-related adverse events after treatment with anti-microtubule drugs;
• Received taxane and/or capecitabine-containing adjuvant/neoadjuvant chemotherapy within 1 year prior to the first study treatment;
• Received prior first-line chemotherapy containing a taxane or capecitabine;
• Symptomatic central nervous system metastases;
• Inability to take or absorb oral medications;
• 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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Arm A; Taxane plus Intermittent Capecitabine	Drug: Taxane plus Intermittent Capecitabine; Eligible patients will receive treatment with taxane (paclitaxel, nab-paclitaxel or docetaxel , the dosage reference to related prescribing information or clinical practice by investigators) plus capecitabine (1000 mg/ m2 twice daily D1-14 Q3W) for 6 ~8 cycles(for the the patients with SD, PR or CR after 6~8 cycles treatment could choose to receive continuous combination therapy or capecitabine maintenance mono therapy ), or be treated until disease progression, unacceptable toxicity or patient request for withdrawal, whichever occurs first. Each cycle is 3 weeks in duration.
Experimental: Arm B; Utidelone plus Intermittent Capecitabine	Drug: Utidelone plus Intermittent Capecitabine; Eligible patients will receive treatment with utidelone (30 mg/ m2 /day D1-5 Q3W) plus capecitabine (1000 mg/ m2 twice daily D1-14 Q3W) for 6 ~8 cycles(for the the patients with SD, PR or CR after 6~8 cycles treatment could choose to receive continuous combination therapy or capecitabine maintenance mono therapy), or be treated until disease progression, unacceptable toxicity or patient request for withdrawal, whichever occurs first. Each cycle is 3 weeks in duration.
Active Comparator: Arm C; Taxane plus Metronomic Capecitabine	Drug: Taxane plus Metronomic Capecitabine; Eligible patients will receive treatment with taxane (paclitaxel, nab-paclitaxel or docetaxel , the dosage reference to related prescribing information or clinical practice by investigators) plus capecitabine ( 500 mg three times daily on days 1-21 Q3W) for 6 ~8 cycles(For the the patients with SD, PR or CR after 6~8 cycles treatment could choose to receive continuous combination therapy or capecitabine maintenance mono therapy), or be treated until disease progression, unacceptable toxicity or patient request for withdrawal, whichever occurs first. Each cycle is 3 weeks in duration.
Experimental: Arm D; Utidelone plus Metronomic Capecitabine	Drug: Utidelone plus Metronomic Capecitabine; Eligible patients will receive treatment with utidelone (30 mg/ m2 /day D1-5 Q3W) plus capecitabine (500 mg three times daily on days 1-21 Q3W) for 6 ~8 cycles(for the the patients with SD, PR or CR after 6~8 cycles treatment could choose to receive continuous combination therapy or capecitabine maintenance mono therapy ), or be treated until disease progression, unacceptable toxicity or patient request for withdrawal, whichever occurs first.
