Athira Pharma Presents Preclinical Data Demonstrating New Insights into the Mechanism by Which Fosgonimeton Protects Neurons from Alzheimer’s Disease-Related Pathology at the Alzheimer’s Association International Conference (AAIC) 2024
Fosgonimeton mitigated amyloid-β-induced toxicity, lowered pTau levels and reduced disruption of protein clearance mechanisms that may contribute to pTau pathology
Fosgonimeton treatment, alone and in combination with lecanemab, protected cultures of primary neurons from the toxic effects of amyloid-β
BOTHELL, Wash., July 31, 2024 (GLOBE NEWSWIRE) -- Athira Pharma, Inc. (NASDAQ: ATHA), a late clinical-stage biopharmaceutical company focused on developing small molecules to restore neuronal health and slow neurodegeneration, presented new preclinical data further highlighting the therapeutic potential of fosgonimeton at the Alzheimer’s Association International Conference (AAIC) 2024, being held in Philadelphia from July 28-Aug. 1, 2024.
“We are pleased to be presenting new preclinical data at AAIC 2024 that further demonstrate the broad neuroprotective activity of fosgonimeton and its effects on Alzheimer’s disease-related protein pathology,” said Kevin Church, Ph.D., Chief Scientific Officer of Athira. “Previous preclinical studies have shown that fosgonimeton protects neurons through several mechanisms, including reducing inflammation, improving mitochondrial function, activating prosurvival signaling pathways, and reducing levels of pTau. Here, we described potential mechanisms as to how fosgonimeton treatment may impact levels of key pathological proteins in Alzheimer’s disease models. We also demonstrated that the neuroprotective ability of fosgonimeton against amyloid-β-induced toxicity in primary neurons is maintained in the presence of lecanemab, and, in some conditions, the combination of fosgonimeton and lecanemab led to numerically higher levels of neuroprotection”
“These preclinical data are compelling as they showed fosgonimeton attenuated amyloid-β-induced autophagic impairments in primary cortical neurons, which may have important implications regarding the attenuation of pTau pathology in Alzheimer’s disease,” stated Mark Litton, Ph.D., President and Chief Executive Officer of Athira. “Preclinical data such as these support our novel approach to targeting the neurotrophic HGF system as a potential treatment for Alzheimer’s disease and add more insights into the pleotropic effect of fosgonimeton in Alzheimer’s disease pathology. We look forward to potentially demonstrating how enhancing this system may translate into clinical benefit.”
AAIC 2024 Presentation Details
Title: Fosgonimeton attenuates amyloid-β-induced autophagic impairments in primary cortical neurons
Poster: #49
Date/Time: Wednesday, July 31, 8:00 a.m. ET – 4:15 p.m. ET
Presenter: Sherif Reda, Ph.D., Associate Director, Discovery Biology, Athira Pharma
Highlights of this presentation show that:
- Fosgonimeton can mitigate amyloid-β-induced disruption of autophagy, an essential cellular process that plays a key role in the removal of pathological proteins, such as pTau, and is known to be impaired in Alzheimer’s disease.
- Improvement in autophagy may partly explain the reduction in pTau observed in these models and suggest that fosgonimeton may have beneficial impacts on key indicators of protein pathology, and the associated neurodegeneration in Alzheimer’s disease.
Title: Neuroprotective effects of fosgonimeton and amyloid-β-targeting monoclonal antibodies against amyloid-β toxicity in primary neuron culture
Poster: #50
Date/Time: Wednesday, July 31, 8:00 a.m. ET – 4:15 p.m. ET
Presenter: Robert W. Taylor, PhD, Director, Discovery Biology, Athira Pharma
Highlights of this presentation show that:
- Fosgonimeton is neuroprotective against amyloid-beta-mediated toxicity in primary neurons, either alone or in combination with lecanemab, and, in some conditions, the combination of fosgonimeton and lecanemab led to numerically higher levels of neuroprotection.
- The data support the continued investigation of fosgonimeton and Aβ-mAbs as a potential combination therapy for the treatment of Alzheimer’s disease.

About Fosgonimeton
Fosgonimeton is a potentially first-in-class, once daily, subcutaneously administered small molecule drug candidate. Targeting the protection and repair of neuronal networks, fosgonimeton has disease-modifying potential to address a broad range of neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, and dementia with Lewy bodies.
About the Phase 2/3 LIFT-AD Clinical Trial
The Phase 2/3 LIFT-AD clinical trial is a randomized, double-blind, placebo-controlled clinical trial evaluating once-daily subcutaneous injections of fosgonimeton 40 mg compared to placebo in people with mild-to-moderate Alzheimer’s disease. Topline results from the trial, which enrolled approximately 315 patients, is targeted by the end of the third quarter of 2024. The primary endpoint of LIFT-AD is the Global Statistical Test (GST), a combination of the results from the co-key secondary endpoints ADAS-Cog11 and ADCS-ADL23, measurements of cognition and function, respectively. Additional key secondary and exploratory endpoints include changes in plasma biomarkers of neurodegeneration, protein pathology, and neuroinflammation. Additional information about the LIFT-AD study can be found at: NCT04488419.
