A Pivotal Phase II Clinical Trial of Utidelone Injection Plus Capecitabine in HER2-negative Breast Cancer Patients With Brain Metastases

November 26, 2025 updated by: Biostar Pharma, Inc.

A Pivotal Phase II Clinical Trial of Utidelone Injection (UTD1) Plus Capecitabine (CAP) in HER2-negative Breast Cancer Patients With Brain Metastases

This study is a multicenter, two-stage clinical trial to evaluate the efficacy and safety of utidelone in combination with capecitabine in patients with HER2-negative breast cancer with brain metastases. Patients will be enrolled to receive treatment of utidelone alone or in combination with capecitabine.

The objectives both in stage I and stage II are to evaluate the intracranial and systemic efficacy and safety of utdelone plus capecitabine for the treatment of HER2-negative breast cancer patients with brain metastases.

Description

Inclusion Criteria:

  2. Based on screening contrast-enhanced brain MRI, patients must have at least one measurable intracranial lesion according to RECIST 1.1 (≥1.0 cm in size) .
  3. Male or female aged ≥18 years.
  4. ECOG PS 0 or 1.
  5. Have a life expectancy of at least 3 months.
  6. Have adequate baseline hematologic parameters.
  7. Have adequate hepatic and renal function.
  8. ≤ 3 prior lines of chemotherapy in advanced or metastatic setting.

Women of childbearing potential, unless hysterectomy or oophorectomy or postmenopausal for at least 12 consecutive months, must use an effective method of avoiding pregnancy (including oral, transdermal, or implanted contraceptives [any hormonal method in conjunction with a secondary method], intrauterine device, female condom with spermicide, diaphragm with spermicide, absolute sexual abstinence, use of condom with spermicide by sexual partner or sterile [at least 6 months prior to study drug administration] sexual partner) for at least 4 weeks prior to study drug administration, during study and up to 6 months following the last dose of study drug. Cessation of birth control after this point should be discussed with a responsible physician. Investigator will discuss with patient on the above points and the patient agreement will be documented in the source document. The investigator should ensure that the patient is using an effective method of avoiding pregnancy as per protocol. In case of Male patients: Either patient partners or patients themselves must use an effective method of avoiding pregnancy for at least 4 weeks prior to study drug administration, during study and up to 6 months following the last dose.
  10. Patients must be able to follow the study visit schedule, and must be able of sign and give informed consent in accordance with institutional review board.

Exclusion Criteria:

  1. Leptomeningeal metastasis confirmed by MRI and/or cerebrospinal fluid cytology.
  2. Any intracranial lesion thought to require immediate local therapy, including (but not limited to) a lesion in an anatomic site where increase in size or possible treatment-related edema may pose risk to patient (e.g. brain stem lesions).
  3. Have poorly controlled (> 1/week) generalized or complex partial seizures, or manifest neurologic progression due to brain metastases notwithstanding CNS-directed therapy.
  4. Had evidence of intracranial hemorrhage within 3 months before study treatment.
  5. Had evidence of hemoptysis within 6 months before study treatment. Or bleeding or evidence of coagulopathy within 4 weeks before study treatment.
  6. Undergone major surgical procedures within 4 weeks or not fully recovered from surgery before study treatment.
  7. Patients who have received anti-tumor therapies less than 2 weeks before the first dose of investigational product, including endocrine therapy, chemotherapy, radiotherapy, biotherapy, targeted therapy, immunotherapy or antibody-drug conjugate therapy.
  8. Persistent toxicities caused by previous antitumor therapy (excluding alopecia), not yet improved to CTCAE v5.0 grade ≤ 1 or baseline.

For patients with previous capecitabine treatment, the prior use of capecitabine meets any of the following criteria: A) The best response during prior capecitabine combination therapy or monotherapy is Progressive Disease (PD); B) Have received capecitabine treatment within 6 months prior to the first study treatment.
  13. Patients who are pregnant (positive pregnancy test) or lactating.
  14. Patients with other malignancies over the past 5 years, except for inactive tumors with good prognosis, including resected basal cell and squamous cell carcinoma of the skin, in-situ carcinoma of the cervix, or papillary thyroid cancer.
