Atossa Therapeutics Provides Information on FDA Expanded Access Policy and Requests


SEATTLE, July 17, 2019 (GLOBE NEWSWIRE) — Atossa Therapeutics Inc. (Nasdaq:ATOS), a clinical-stage biopharmaceutical company developing novel therapeutics and delivery methods for breast cancer and other breast conditions, today reported that patients and their doctors can now visit the company’s website to obtain information about gaining access to the company’s proprietary Endoxifen pursuant to the FDA’s “Expanded Access” guidelines. The company’s website includes its  Expanded Access policy as well as an automated form that can be used by physicians to request that their patients be considered for this program: – ea-form.

Sometimes called “compassionate use”, Expanded Access is a potential pathway for a physician to access an investigational medical product (drug, biologic, or medical device) for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available for their patient with a serious disease or condition, or an immediately life-threatening condition. For more information about this process, please see the FDA website: FDA Expanded Use Website.

In December 2018, Atossa began providing its oral Endoxifen to a pre-menopausal, estrogen-receptor positive (ER+), lacking CYP2D6 function, breast cancer patient under an FDA-approved “Single-Patient Expanded Access” IND. The purpose of this therapeutic approach was to reduce activity of the cancer cells prior to surgery. The patient received daily doses of Atossa’s oral Endoxifen for approximately three weeks prior to surgery. There were no safety or tolerability issues and her surgery was successfully completed. The cancer cell biological activity was reduced, based on the estrogen receptor activity of the tumor cells and a 50 percent reduction in Ki-67. The FDA subsequently approved the use of Atossa’s oral Endoxifen for this patient following her surgery under the same program.
