 SEATTLE, Sept. 02, 2021 GLOBE NEWSWIRE -- Atossa Therapeutics, Inc. Nasdaq:ATOS, a clinical stage biopharmaceutical company seeking to discover and develop innovative medicines in areas of significant unmet medical need in oncology and infectious diseases with a current focus on breast cancer and COVID-19, today announced it has received approval from the Swedish Ethics Review Authority to begin a Phase 2 clinical study of oral Endoxifen for the reduction of mammographic breast density MBD. MBD is an emerging public health issue affecting more than 10 million women in the United States and many more worldwide.

Additional studies show a correlation between reducing MBD and a reduction in the incidence of breast cancer.
