Atossa Therapeutics announced the completion of patient dosing in its Phase 2 Karisma-Endoxifen clinical trial. This study, which enrolled 240 premenopausal women with mammographic breast density (MBD), aims to reduce MBD, a risk factor for breast cancer. The trial, fully enrolled in November 2023, tested daily doses of 1 mg and 2 mg (Z)-endoxifen versus placebo over six months. Results will be important for potential Phase 3 trials. MBD reduction is linked to a 50%-63% decrease in breast cancer risk over 3-15 years. Atossa is focusing on breast cancer treatments, with five ongoing Phase 2 studies.
Atossa Therapeutics announced its first-quarter 2024 financial results, showcasing positive data from the EVANGELINE study with a 100% disease control rate. They also initiated a study combining (Z)-endoxifen with abemaciclib, ended Q1 2024 with $84.0 million in cash, and appointed Dr. Tessa Cigler to the Board of Directors. The company is focused on developing innovative oncology medicines, particularly for breast cancer. Despite having no revenue, the operating expenses were $7.0 million, with a decrease from the previous year.
