Atossa Therapeutics Contracts with NYC Health + Hospitals/Metropolitan for Coronavirus HOPE Clinical Study

Study Designed to Evaluate Atossa’s Combination Therapy AT-H201 to Reduce Patient Time on a Ventilator

SEATTLE, April 27, 2020 (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, today announced that it has contracted with NYC Health + Hospitals/Metropolitan in New York City to conduct the NY HOPE Study of Atossa’s proprietary combination drug therapy called AT-H201. The NY HOPE Study will evaluate AT-H201 in COVID-19 patients on ventilators with the goal of reducing the amount of time on ventilators.

“We are honored to be working with NYC Health + Hospitals/Metropolitan and Dr. Getaw Hassen, who are on the front lines of this unprecedented health crisis,” stated Dr. Steven Quay, President and CEO of Atossa Therapeutics. “The NY HOPE Study is a vital step in developing this new therapy for critically ill COVID-19 patients.”

“Managing patient care and ventilator use has become a major challenge,” commented Getaw Hassen, M.D., Ph.D., Emergency Physician, at NYC Health + Hospitals/Metropolitan and the principal investigator of the NY HOPE Study. “We have an urgent need for a therapy to reduce reliance on ventilators and we are looking forward to playing a key role in what could be a much-needed solution for our sickest COVID patients.”

The NY HOPE Study will assess the safety and efficacy of AT-H201 administered via inhalation in COVID-19 patients on mechanical ventilation support. Subject to FDA and IRB input, the study is currently designed as follows: Thirty-nine patients will be enrolled in the active treatment group and compared to the outcomes of 66 patients in a matched retrospective control group. Patients will be dosed with AT-H201 each day in addition to the standard of care, while on mechanical ventilation for up to seven days and will be followed up during hospitalization and for 28 days after discharge. The primary objectives are to determine the number of ventilator-free days after patients are removed from ventilators following the initial airway intervention; oxygenation levels; and survival rates.

Secondary efficacy endpoints include a variety of lung function parameters and time in ICU. Secondary safety endpoints include markers of coagulation and system function.

The NY HOPE Study is currently pending IRB approval and will not commence without IRB and all necessary regulatory approvals, including FDA. Atossa has filed comprehensive provisional patent applications related to AT-H201.

About Atossa’s COVID-19 HOPE Program

Atossa’s COVID-19 program is called “COVID-19 HOPE,” which is an acronym for AT-H201 in COVID-19 patients for Pulmonary Evaluation. The intended primary function of the drug combination AT-H201 is to essentially mimic the function of the antibodies formed from a vaccine by blocking the ability of the virus to enter the target cells; a vaccine that may not be available for more than a year. There are five known key steps the coronavirus must take to signal the cell to open up and let the virus in. AT-H201 is being designed to function like a “chemical vaccine” by blocking all five of those steps, similar to what antibodies would be expected to do when a vaccine is administered. With AT-H201, the virus should be unable to enter the cell because its “keys” that would otherwise open the door into the cell surface, are disabled. Atossa expects that its AT-H201 drug combination can be developed more quickly than a traditional vaccine.

The NY HOPE Study is a critical step in determining safety and efficacy of AT-H201 and in bringing this new therapy to the market.
