Atossa Genetics Announces Preliminary Results from

Phase 1 Study of Oral Endoxifen

All Objectives Successfully Met

Conference Call To Be Held Today at 10 am Eastern Time

SEATTLE, October 25, 2017 -- Atossa Genetics Inc. (NASDAQ: ATOS), a clinical-stage pharmaceutical company developing novel therapeutics and delivery methods for breast cancer and other breast conditions, reported preliminary results from its Phase 1 study of its proprietary oral Endoxifen. All objectives were successfully met:

These data demonstrate the suitability of oral Endoxifen for further clinical development.

The Phase 1 Study

The Phase 1 study was a double-blind, placebo-controlled, repeat dose study of 48 healthy female subjects. Atossa assessed safety, tolerability and the pharmacokinetics of proprietary formulations of both topical and oral Endoxifen dosage forms in varying dose levels over 28 days. The study was conducted in two parts based on route of administration. Preliminary results from the topical arm of the study were announced on September 14, 2017.

Atossa’s Proprietary Endoxifen

Endoxifen is an active metabolite of tamoxifen. Tamoxifen is an FDA-approved drug to prevent new breast cancer as well as recurrent breast cancer in breast cancer patients. Tamoxifen is a “pro-drug” meaning that it must be broken down by the liver into active compounds (metabolites), of which Endoxifen is the most active. It is these active metabolites that have the therapeutic effect.

Oral Endoxifen. Although approximately one million breast cancer survivors take tamoxifen annually, up to half of them do not fully benefit from tamoxifen, meaning they are “refractory,” for a number of reasons including that they do not properly metabolize tamoxifen into its active metabolites. Low endoxifen levels in breast cancer patients taking oral tamoxifen are associated with an increased risk of recurrence or the development of new breast tumors. Thus providing oral Endoxifen directly to the patient without having to be metabolized may help to address this problem.

Topical Endoxifen. A condition called breast density (or, MBD), typically diagnosed by a mammogram, has been shown to be an independent breast cancer risk factor. To date, 30 states require that findings of MBD be directly communicated to the patient. We believe a topical form of Endoxifen could potentially reduce MBD. Although oral tamoxifen has been shown to reduce MBD, the benefit-cost ratio is not acceptable to most physicians and their patients. For example, it is estimated that less than 5% of women at an increased risk of developing breast cancer including those with MBD take oral tamoxifen to prevent breast cancer because of the risk of, or actual side-effects of, oral tamoxifen. We are planning a Phase 2 study of topical Endoxifen in Stockholm Sweden for the treatment of MBD.

Based on the number of women with MBD and the number of patients who have survived breast cancer but are not fully benefiting from tamoxifen, Atossa estimates that the potential markets for its proprietary oral and topical formulations of Endoxifen could potentially exceed $1 billion in annual sales.

Next Steps

“Based on these positive preliminary results, we are advancing our oral Endoxifen into Phase 2 studies” commented Dr. Steven C. Quay, CEO and President. “We expect our initial Phase 2 study will be in women who are refractory to tamoxifen and we expect to begin that study in the first quarter of 2018,” continued Dr. Quay.

Breast Cancer Statistics

The American Cancer Society (ACS) estimates that approximately 250,000 women will be diagnosed with breast cancer in the United States this year and that approximately 40,000 will die from the disease. It is the second leading cause of cancer death in American women. Although about 100 times less common than women, breast cancer also affects men. The ACS estimates that the lifetime risk of men getting breast cancer is about 1 in 1,000; 2,470 new cases of invasive breast cancer will be diagnosed; and 460 men will die from breast cancer in 2017.
