Atossa Therapeutics Announces Two-Year Update of FDA-Approved Expanded Access Treatment with Endoxifen

About this update from Atossa Therapeutics, Inc.

[{"type":"text","content":"SEATTLE, Feb. 03, 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 with a current focus on breast cancer and COVID-19, announces updated findings following 26 months of Expanded Access (or “compassionate use”) single-patient studies of Atossa’s Endoxifen. “To date, the patient has not had a recurrence of breast cancer, as assessed by clinical breast examination and mammography; has not had treatment-related changes in periodic laboratory blood tests and general clinical examinations; and, the treatment has been well tolerated, including an absence of typical vasomotor symptoms commonly associated with tamoxifen (for example, night sweats and hot flashes), an FDA-approved drug frequently prescribed for breast cancer treatment,” commented Sidney Goldblatt, M.D., Principal Investigator. At the end of 2018, the FDA authorized a single-patient study under its Expanded Access, or compassionate use program, for this breast cancer patient to receive Atossa’s oral Endoxifen in the “window of opportunity” between diagnosis of breast cancer and surgery. Following surgery, an additional compassionate use authorization was granted by the FDA for the same patient, who has now continued to take oral Endoxifen in the adjuvant setting following her surgery. She has now taken Atossa’s oral Endoxifen for approximately 26 months and is continuing to take oral Endoxifen daily under these authorizations. “This patient, like many breast cancer patients, was reluctant to take tamoxifen because of the well-documented side effects associated with that drug and because she lacked the proper liver enzymes to properly metabolize tamoxifen,” commented Steve Quay, Ph.D., M.D., Atossa’s President and CEO. “We are very encouraged by this patient’s experience with our Endoxifen over the past two years. Her experience serves as a model for ongoing development efforts.” About Atossa Therapeutics Atossa Therapeutics, Inc. is a clinical-stage biopharmaceutical company seeking to discover and develop innovative medicines in areas of significant unmet medical need with a current focus on breast cancer and COVID-19.
