Breast Cancer - Odonate CONTESSA

CONTESSA is a multinational, multicenter, randomized, Phase 3 study of tesetaxel in patients with HER2 negative, HR positive LA/MBC previously treated with a taxane in the neoadjuvant or adjuvant setting. The primary objective of the study is to compare the efficacy of tesetaxel plus a reduced dose of capecitabine versus the approved dose of capecitabine alone based on progression-free survival (PFS) as assessed by an Independent Radiologic Review Committee (IRC). Approximately 600 patients will be enrolled.

Eligibility Criteria

  1. Female or male patients at least 18 years of age
  2. Histologically or cytologically confirmed breast cancer
  3. HER2 negative disease based on local testing: American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) guidelines should be utilized for assessing HER2 status
  4. HR (estrogen receptor [ER] and/or progesterone receptor [PgR]) positive disease based on local testing: ASCO/CAP guidelines should be utilized for assessing HR status
  5. Measurable disease per RECIST 1.1 or bone-only disease with lytic component
      • Patients with bone-only metastatic cancer must have a lytic or mixed lytic-blastic lesion that can be accurately assessed by computerized tomography (CT) or magnetic resonance imaging (MRI). Patients with bone-only disease without a lytic component (ie, blastic-only metastasis) are not eligible.

This study is for patients age 18 Years and older.
