SEATTLE, Sept. 01, 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 with a current focus on breast cancer and COVID-19, today announced a positive interim safety assessment from the first cohort of healthy participants in the Phase 1 clinical study using Atossa's proprietary drug candidate AT-301 administered by nasal spray. This first group of 8 participants received a single dose of either AT-301A (placebo) or AT-301B (active drug). This blinded, positive assessment by the safety committee allows the study to now enroll the next cohort.
"This favorable safety review is an important milestone," commented Steven Quay, M.D., Ph.D., Atossa's President and CEO. "First in human studies typically have an early safety assessment to ensure the drug is not harming participants and this positive assessment allows us to continue enrolling patients, including at higher doses and in repeated dose cohorts. We look forward to completing this Phase 1 safety and tolerance study so that we can begin to investigate the safety and efficacy of AT-301 in preventing and/or mitigating a COVID-19 infection."
The Phase 1 study is a double-blinded, randomized, and placebo-controlled safety study of AT-301 nasal spray in 32 healthy adult subjects divided into two study groups. Part A consists of two single-dose cohorts receiving either active therapy, AT-301B, or the placebo comparator AT-301A at two different doses. Part B is a multiple dose arm with cohorts receiving either AT-301A or AT-301B for 14 days at two different doses. The primary objective of the study is to evaluate the safety and tolerability of single and multiple doses of AT-301 administered via nasal instillation to healthy volunteers. Secondary objectives are to assess the incidence and severity of local irritation and bronchospasm following administration of AT-301 via nasal instillation. The study is being conducted in Australia.
