Business	1. Business Odonate Therapeutics, Inc. (“Odonate” or the “Company”) is a pharmaceutical company dedicated to the development of best-in-class therapeutics that improve and extend the lives of patients with cancer. The Company’s initial focus is on the development of tesetaxel, 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 (“MBC”), tesetaxel was shown to have significant, single-agent antitumor activity in two multicenter, Phase 2 studies. The Company is currently conducting three studies in breast cancer, including a multinational, multicenter, randomized, Phase 3 study in patients with MBC, known as CONTESSA. The Company’s goal for tesetaxel is to develop an effective chemotherapy choice for patients that provides quality-of-life advantages over current alternatives. As of March 31, 2020, the Company had $153.1 million in cash. The Company has incurred operating losses and negative cash flows from operations since inception. Management believes that the Company’s existing cash will be sufficient to meet the Company’s anticipated cash requirements through at least one year from the date this Quarterly Report on Form 10-Q is filed with the U.S. Securities and Exchange Commission (the “SEC”).
