- Initiated open label extension for LIFT-AD and ACT-AD trials of ATH-1017 allowing for an additional six months of treatment

- ACT-AD and LIFT-AD are actively recruiting; topline data of ACT-AD are targeted by first half 2022 and topline data from LIFT-AD are targeted by end of 2022

BOTHELL, Wash., Aug. 16, 2021 (GLOBE NEWSWIRE) -- Athira Pharma, Inc. (NASDAQ: ATHA), a late clinical-stage biopharmaceutical company focused on developing small molecules to restore neuronal health and stop neurodegeneration, today reported its financial results for the second quarter ended June 30, 2021 and provided an update on the company’s operations.

“In the second quarter of 2021, we made significant advancements across our corporate and clinical initiatives,” said Mark Litton, Ph.D., MBA, Chief Operating Officer at Athira. “We recently initiated an open label extension study for our ongoing Phase 2/3 LIFT-AD and Phase 2 ACT-AD studies of ATH-1017 in patients living with mild-to-moderate Alzheimer’s disease, allowing for all study participants to receive active drug treatment for an additional 26 weeks. We anticipate that the additional data obtained from this extension will provide a more comprehensive understanding of the long-term safety and efficacy profile, and when combined with the promising preclinical and early clinical data generated both internally and externally, will inform our clinical development strategy.”

Dr. Litton continued, “We remain encouraged by the therapeutic potential of ATH-1017 to improve clinical outcomes and restore neuronal health through an approach that focuses on neuronal regeneration, agnostic to the underlying disease pathology. In addition to Alzheimer’s disease, we plan to evaluate ATH-1017 in Parkinson’s disease dementia, and we remain committed to advancing our expanding pipeline of small molecule compounds. We look forward to providing updates on our progress as we deliver on our strategic plan and our mission to improve the lives of those suffering from neurological diseases.”

Clinical Development and Upcoming Milestones
ATH-1017: A small molecule therapeutic specifically designed to enhance the activity of hepatocyte growth factor (HGF) and its receptor, MET, to impact neurodegeneration and regenerate brain tissue. ATH-1017 is currently being evaluated in two randomized, double-blind, placebo-controlled trials designed to evaluate the safety and efficacy of the investigational therapeutic in individuals with mild-to-moderate Alzheimer’s disease.
Recent Advancements
	•	Initiated Open Label Extension Study for LIFT-AD and ACT-AD trials of ATH-1017
			•	Following completion of the 26-week treatment period during the LIFT-AD or ACT-AD trials, patients from both the placebo and active groups may elect to continue the open label extension and receive treatment with ATH-1017 at the high dose (70 mg/day) for up to an additional 26 weeks. Investigators and patients will remain blinded to treatment group assignment in the original trials.
	•	Presented Ph1a/b ATH-1017 data at the Alzheimer’s Association International Conference 2021 (AAIC)
			•	Results support the clinical utility of quantitative electroencephalogram (qEEG) biomarker of brain circuitry activity, and the translational utility for PK/PD modeling and dose-optimization across preclinical and clinical models of mild-to-moderate Alzheimer’s disease.
Upcoming Milestones
	•	The company anticipates reporting topline data from ACT-AD by the first half of 2022, and topline data from LIFT-AD by the end of 2022.
	•	A Phase 2 trial of ATH-1017 for treatment of Parkinson’s disease dementia is targeted to initiate by the end of 2021.
Pipeline
ATH-1020: Novel, small molecule compound designed to be an orally available once-daily treatment, to activate the HGF/MET system and to distribute to the central nervous system as a potential candidate for neurodegenerative disorders.
Upcoming Milestones
	•	IND filing expected by end of 2021. IND-enabling studies are proceeding for ATH-1020. As planned, Athira is targeting an IND submission to the U.S. Food and Drug Administration (FDA) by the end of 2021.
Recent Corporate Updates:
	•	Mark Litton, Ph.D., MBA, in his capacity as Chief Operating Officer, has assumed day-to-day leadership responsibilities for the Company.
	•	Rachel Lenington, MBA, has been appointed as Chief Technology Officer, Head of Product Development Strategy.
			•	Ms. Lenington brings more than 20 years of biopharmaceutical leadership experience at leading organizations including Seagen Inc, the Bill & Melinda Gates Foundation and Amgen, with roles spanning R&D decision making, drug development and commercialization, and partnership management.
	•	Mark Worthington, J.D., has been appointed as General Counsel.
			•	Mr. Worthington previously worked with Athira as outside corporate counsel. He brings more than 20 years of experience advising both private and public companies on a wide range of corporate governance, compliance and transactional matters, including public offerings, mergers and acquisitions, and joint ventures, and worked closely with executive management teams on strategic business and legal matters.
	•	On August 5, 2021, we announced that Dr. Tadataka Yamada, M.D., a director and Chair of our board of directors, died unexpectedly of natural causes on August 4, 2021.
