SEATTLE, Oct. 01, 2024 (GLOBE NEWSWIRE) -- Atossa Therapeutics, Inc. (Nasdaq: ATOS) ("Atossa" or the "Company"), today announced its recognition and support of Breast Cancer Awareness Month this October; highlighting the importance of increasing awareness, advancing research, and driving progress toward innovative treatments for breast cancer. Approximately one in eight women will be diagnosed with breast cancer in their lifetime, so this annual campaign serves as a powerful reminder of the ongoing need for education, early detection, prevention, and access to effective treatment options. Atossa Therapeutics is a clinical-stage biopharmaceutical company developing innovative medicines for breast cancer.
This year’s Breast Cancer Awareness Month takes on added significance with the recent implementation of the U.S. Food and Drug Administration’s (FDA) updated rule under the Mammography Quality Standards Act (MQSA). The new rule, which became effective on September 10, 2024, requires healthcare providers to notify women of their breast density results following a mammogram. Dense breast tissue is a known risk factor for breast cancer, and women with this condition are encouraged to consult with their healthcare providers about additional screening options to ensure earlier detection.
“As we honor Breast Cancer Awareness Month, it’s essential to reflect on the importance of education and early detection in the fight against breast cancer,” said Steven Quay, M.D., Ph.D., Atossa’s President and Chief Executive Officer. “While significant progress has been made, continued research is critical to improve outcomes for the millions of women impacted by breast cancer every year. At Atossa, we are dedicated to advancing innovative treatments and increasing awareness of risk factors, such as dense breast tissue, that can contribute to missed diagnoses.”
Atossa is currently evaluating its lead asset, (Z)-endoxifen, in multiple phase 2 clinical trials, including the Karisma-Endoxifen study, which is investigating the potential for (Z)-endoxifen to reduce mammographic breast density in premenopausal women with measurable density. Data from this trial is expected in the fourth quarter of 2024. Currently, there are no approved treatments available to reduce breast density, a condition that can obscure tumors during mammograms and increase the risk of undiagnosed cancer.
Atossa is also supporting the SMART (Stockholm MAmmography Risk stratified Trial) study, a recently announced phase 2 study designed to validate an innovative, artificial intelligence driven, breast cancer risk assessment model. The study will test an individualized, imaging-based screening model designed to identify women with the highest risk of developing breast cancer in the next two years. If the model is validated for therapeutic use, it could serve as the foundation for a future phase 3 trial investigating (Z)-endoxifen in the breast cancer prevention setting.
About (Z)-Endoxifen
(Z)-endoxifen is one of the most potent Selective Estrogen Receptor Modulators (SERM) for estrogen receptor inhibition and also causes estrogen receptor degradation. It has also been shown to have efficacy in the setting of patients with tumor resistance to other hormonal treatments. In addition to its potent anti-estrogen effects, (Z)-endoxifen has been shown to target PKCβ1, a known oncogenic protein, at clinically attainable blood/tissue concentrations. Finally, (Z)-endoxifen appears to deliver similar or even greater bone agonistic effects while resulting in little or no endometrial proliferative effects compared with standard treatments, like tamoxifen.
Atossa is developing a proprietary oral formulation of (Z)-endoxifen that does not require liver metabolism to achieve therapeutic concentrations and is encapsulated to bypass the stomach, as acidic conditions in the stomach convert a significant proportion of (Z)-endoxifen to the inactive (E)-endoxifen. Atossa’s (Z)-endoxifen has been shown to be well tolerated in Phase 1 studies and in a small Phase 2 study of women with breast cancer. (Z)-endoxifen is currently being studied in five Phase 2 trials: one in healthy women with measurable breast density, one in women diagnosed with ductal carcinoma in situ, and two other studies including the EVANGELINE study in women with ER+/HER2- breast cancer. Atossa’s (Z)-endoxifen is protected by four issued U.S. patents and numerous pending patent applications.
