On February 28, 2019 Odonate Therapeutics, Inc. (NASDAQ: ODT), a pharmaceutical company dedicated to the development of best-in-class therapeutics that improve and extend the lives of patients with cancer, reported the acceptance for presentation at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2019 of an abstract describing results of preclinical studies of tesetaxel, Odonate’s investigational, orally administered taxane (Press release, Odonate Therapeutics, FEB 28, 2019, View Source [SID1234533870]). These preclinical results indicate that, following oral administration, tesetaxel achieves brain concentrations that exceed concentrations required for tumor killing for a sustained period of time. This is in contrast to paclitaxel and docetaxel, the most commonly prescribed taxanes, which do not substantially cross the blood-brain barrier. New therapies are needed for patients with tumors that have metastasized to the brain from other organs, such as the breast or the lung, as well as patients with primary brain tumors. The AACR (Free AACR Whitepaper) Annual Meeting 2019 will be held March 29 – April 3, 2019 in Atlanta, Georgia. The abstract for this presentation was made publicly available yesterday and can be found on the AACR (Free AACR Whitepaper) Annual Meeting 2019 Itinerary Planner or by clicking the title below.

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.
