Atossa Therapeutics, Inc. (Nasdaq: ATOS)  is a clinical-stage biopharmaceutical company seeking to discover and develop innovative medicines in areas of significant unmet medical need. Atossa’s current focus is on breast cancer and COVID-19. On March 11, 2021 announced the FDA has issued a “Safe to Proceed” letter under their Expanded Access Pathway, permitting the use of Atossa’s oral Endoxifen as a treatment in an ovarian cancer patient. The patient is being treated at the University of Washington Medical Center by Dr. Barbara Goff, Surgeon-in-Chief. Under the FDA expanded access program, the use of Atossa’s proprietary oral Endoxifen is restricted solely to this patient. Approval from the Institutional Review Board (IRB) must be obtained prior to providing oral Endoxifen to this patient.

“Dr. Goff recently contacted Atossa with an interest in gaining access to our Endoxifen under the FDA’s expanded access, or compassionate use, program for one of her patients. The patient has recurrent ovarian cancer and recently underwent functional molecular genomic testing, using 3D tumor organoid cultures grown in the laboratory from the patient’s tumor. The organoid testing revealed that the combination of Endoxifen and alpelisib produced an exceptional tumor response. We are gratified to be able to help this patient and are anxious to follow her response to this drug combination. If the drug combination shows promise in this patient, Atossa will consider doing additional clinical studies in patients with ovarian cancer” stated, Steven Quay, M.D., Ph.D., Atossa’s President and CEO.  Review the story here.
