Seattle-based Biotech Firm Atossa Therapeutics (ATOS) Announces Q1 Progress

By John F. Heerdink, Jr.

Seattle-based biotech firm Atossa Therapeutics (ATOS), a clinical-stage biopharmaceutical company seeking to discover and develop innovative medicines in areas of significant unmet medical need announced its Q1 2020 Financial Results and confirmed the following progress: 

  • Launched a new drug development program called COVID-19 HOPE to test AT-H201, a novel combination of two drugs that have been previously approved by the FDA for other diseases. The goal of the COVID-19 HOPE program is to develop a therapy to improve lung function and reduce the amount of time that COVID-19 patients are on ventilators. Atossa has applied to the FDA for approval to commence a clinical study in this setting.
  • Announced that Atossa has contracted with NYC Health + Hospitals/Metropolitan in New York City to conduct the COVID-19 HOPE study of AT-H201.
  • Announced positive interim results from Atossa’s Phase 2 study of oral Endoxifen to treat breast cancer in the “window of opportunity” between the diagnosis of breast cancer and surgery. A statistically significant (p = 0.031) reduction of about 74% in tumor cell proliferation was achieved over an average of 22 days of dosing. Proliferation was measured by Ki-67, a recognized standard measurement of breast cancer cell proliferation. Other recent progress with this program includes contracting with Avance Clinical to open a second site for the study in Geelong, Victoria, Australia, with the goal of increasing the rate of enrollment; applying to the Institutional Review Board for approval to open the second site; and, manufacturing sufficient Endoxifen necessary for all patients expected to enroll in this study.
  • Announced that recent input from the FDA on Atossa’s oral Endoxifen program will inform Atossa’s clinical trial strategy and study design both in the U.S. and in Stockholm, Sweden, where Atossa is planning a Phase 2 study to reduce MBD. Atossa plans to commence the MBD study in Stockholm after receiving approval by the European Medical Product Authority (MPA) and the re-opening of mammography clinics in Stockholm following the COVID-19 closures.
“The beginning of 2020 has been eventful both in terms of our accomplishments in moving our Endoxifen clinical programs forward, as well as the launch of our COVID-19 HOPE program,” said Dr. Steven Quay, Atossa’s President and Chief Executive Officer. “We achieved tremendous success with the initial group of patients in our oral Endoxifen window of opportunity Phase 2 study. We look forward to continuing enrollment in our window of opportunity study and to commencing our Endoxifen Phase 2 study in Stockholm, Sweden when the COVID-19 restrictions are eased.”
