About Tesetaxel

Tesetaxel is an investigational, orally administered chemotherapy agent that belongs to a class of drugs known as taxanes, which are widely used in the treatment of cancer. Tesetaxel has several pharmacologic properties that make it unique among taxanes, including: oral administration with a low pill burden; a long (~8-day) terminal plasma half-life in humans, enabling the maintenance of adequate drug levels with relatively infrequent dosing; no history of hypersensitivity (allergic) reactions; and significant activity against chemotherapy-resistant tumors. In patients with metastatic breast cancer, tesetaxel was shown to have significant, single-agent antitumor activity in two multicenter, Phase 2 studies.

About CONTESSA

CONTESSA is a multinational, multicenter, randomized, Phase 3 study of tesetaxel, an investigational, orally administered taxane, in patients with locally advanced or metastatic breast cancer (LA/MBC). CONTESSA is comparing tesetaxel dosed orally at 27 mg/m² on the first day of a 21-day cycle plus a reduced dose of capecitabine (1,650 mg/m²/day dosed orally on days 1-14 of a 21-day cycle) to the approved dose of capecitabine alone (2,500 mg/m²/day dosed orally on days 1-14 of a 21-day cycle) in approximately 600 patients randomized 1:1 with human epidermal growth factor receptor 2 (HER2) negative, hormone receptor (HR) positive LA/MBC previously treated with a taxane in the neoadjuvant or adjuvant setting. Capecitabine is an oral chemotherapy agent that is considered a standard-of-care treatment in LA/MBC. Where indicated, patients must have received endocrine therapy with or without a cyclin-dependent kinase (CDK) 4/6 inhibitor. The primary endpoint is progression-free survival (PFS) assessed by an Independent Radiologic Review Committee (IRC). CONTESSA’s secondary efficacy endpoints are overall survival (OS), objective response rate (ORR) assessed by the IRC and disease control rate (DCR) assessed by the IRC.
