Tesetaxel Every 3 Weeks vs Weekly vs Capecitabine as 1st-line Therapy for Locally Advanced or Metastatic Breast Cancer
Study Details
Study Description
Brief Summary
This study is being conducted to compare the efficacy and safety of tesetaxel administered once every 3 weeks in a 21-day cycle, tesetaxel administered once weekly for 3 consecutive weeks in a 28-day cycle, and capecitabine administered twice daily for 14 consecutive days in a 21-day cycle.

Outcome Measures
Primary Outcome Measures
- Response rate [4 months after the date of randomization of the last patient, which is estimated will occur 16 months after the first patient is randomized]
the percentage of patients with a confirmed complete or partial response, as defined in the revised Response Evaluation Criteria in Solid Tumors (revised RECIST [Version 1.1])
Secondary Outcome Measures
- Clinical benefit rate [12 months after the date of randomization of the last patient, which is estimated will occur 24 months after the first patient is randomized]
the percentage of patients with a complete or partial response of any duration or stable disease lasting ≥ 6 months
- Progression-free survival [12 months after the date of randomization of the last patient, which is estimated will occur 24 months after the first patient is randomized]
the period from the date of randomization to the date when disease progression is first documented or when the patient dies within 6 weeks of the last lesion assessment
- Progression-free survival rate [6 and 12 months after patients' date of randomization]
the percentage of patients who are progression free
- Adverse events [up to 30 days after patients' last dose of study medication]
the percentage of patients with adverse events classified by term and body system
