“We are on the cusp of a potentially transformative milestone as we are fast approaching the expected topline data readout from our Phase 2/3 LIFT-AD clinical trial of fosgonimeton in Alzheimer’s disease (AD) in the second half of this year,” said Mark Litton, Ph.D., President and Chief Executive Officer of Athira. “The totality of clinical and nonclinical data to date support our confidence in the LIFT-AD trial and underscore the potential of our differentiated approach in targeting the neurotrophic HGF system to induce neuroprotective effects across a number of neurodegenerative diseases.”

“We were delighted to welcome Javier San Martin, M.D. as our new Chief Medical Officer. His insight and expertise will be invaluable as we move toward the LIFT-AD data readout and the potential opportunity to deliver fosgonimeton as a new treatment option for AD patients in need of better therapies. In parallel, we continue to progress ATH-1105 in amyotrophic lateral sclerosis (ALS) and expect to initiate a first-in-human study of this oral small molecule drug candidate in the coming months,” added Dr. Litton.

Clinical Development & Pipeline Programs

Athira’s drug development pipeline includes potential first-in-class (fosgonimeton) and next-generation (ATH-1105 and ATH-1020) small molecule drug candidates designed to promote the neurotrophic hepatocyte growth factor (HGF) system, which activates neuroprotective, neurotrophic and anti-inflammatory pathways in the central nervous system. Athira’s drug candidates have distinct properties, which the Company believes may be applicable to a broad range of neurodegenerative diseases.

Fosgonimeton (ATH-1017) – A potentially first-in-class, once daily, subcutaneously administered drug candidate initially targeted for the potential treatment of Alzheimer’s disease.

LIFT-AD Phase 2/3 clinical trial of fosgonimeton in mild-to-moderate Alzheimer’s disease (NCT04488419)

  • Athira expects to report topline data from LIFT-AD in the second half of 2024.

  • In January 2024, Athira announced the completion of enrollment of the LIFT-AD study.

  • The LIFT-AD study is investigating the effects of fosgonimeton 40 mg compared with placebo in mild-to-moderate AD patients who are not receiving background therapy. The primary endpoint is the Global Statistical Test (GST), combining the results from the co-key secondary endpoints of cognition (ADAS-Cog11) and function (ADCS-ADL23), which Athira believes is a comprehensive measure of overall disease burden. Other secondary and exploratory endpoints include changes in plasma biomarkers of neurodegeneration, protein pathology, and neuroinflammation.

Open Label Extension (OLEX) fosgonimeton trial (NCT04886063)

  • Eligible participants who complete the Company’s LIFT-AD or ACT-AD clinical trials and elect to participate in the ongoing OLEX are able to receive up to 48 months of open-label treatment.

  • Greater than 85% of participants who completed either study have elected to enroll in OLEX to date.

  • Currently, more than 65 patients are continuing fosgonimeton treatment beyond 18 months, which is unexpected in a progressive mild-to-moderate Alzheimer’s disease population.

  • Athira believes the OLEX will complement its long-term safety database and provide insights into fosgonimeton’s long-term effects for potentially over four years of investigational treatment.

SHAPE Phase 2 clinical trial of fosgonimeton in Parkinson’s disease dementia and dementia with Lewy bodies (NCT04831281)

  • In December 2023, Athira announced encouraging findings from the exploratory SHAPE Phase 2 clinical trial of fosgonimeton for the potential treatment of Parkinson's disease dementia and dementia with Lewy bodies.

  • Treatment with fosgonimeton 40 mg (n=5) compared to placebo (n=7) showed directional improvements in certain cognitive, functional and biomarker measurements, including ADAS-Cog13, MMSE, and COWAT over the 6-month double-blind treatment period.

  • The primary endpoint of the trial, a composite score of the change in Event-Related-Potential (ERP) P300 latency and cognitive assessment (ADAS-Cog13), was not met by protocoled analysis compared with placebo.

  • Fosgonimeton was generally well tolerated, with a favorable safety profile. There were no treatment-related serious adverse events observed in the study. The most common adverse event in the treatment groups was injection site reactions.

ATH-1105 – A next-generation, orally administered, small molecule drug candidate in development for the potential treatment of ALS.

  • Athira submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration for the evaluation of ATH-1105 as a potential treatment for ALS.

  • Athira expects to initiate a first-in-human study of ATH-1105 in the second quarter of 2024.

  • ATH-1105’s potential is supported by a growing body of preclinical evidence demonstrating statistically significant improvements on nerve and motor function, biomarkers of inflammation and neurodegeneration, and survival in various models of ALS.

  • These data have been presented at a variety of key scientific and medical meetings including the American Association of Neurology (AAN), the Alzheimer’s Association International Congress (AAIC), the Northeast Amyotrophic Lateral Sclerosis Consortium® (NEALS), and the Motor Neurone Disease Association (MNDA).

Corporate

  • In April 2024, the Company announced the appointment of Javier San Martin, M.D., as Chief Medical Officer. Dr. San Martin is an experienced clinical development executive with a strong track record of advancing therapeutics from early development to approval and through commercialization. He joins Athira with more than 25 years of drug development experience, most recently as Chief Medical Officer of Arrowhead Pharmaceuticals.

Recent Presentations and Publications

  • In April 2024, Athira presented a poster at the American Academy of Neurology (AAN) 2024 Annual Meeting, which highlighted preclinical data supporting the continued development of its small molecule candidates targeting the neurotrophic HGF system. The presentation was titled: “Targeting Neurotrophic HGF Signaling for the Treatment of Neurodegenerative Disorders.”

  • In April 2024, Athira published preclinical data supporting the therapeutic potential of fosgonimeton in Alzheimer’s disease in the peer-reviewed journal, Neurotherapeutics. The original research article is titled: “Fosgonimeton attenuates amyloid-beta toxicity in preclinical models of Alzheimer’s disease.”

    • The findings described several mechanisms by which fosgonimeton may disrupt the neurodegenerative cascade of Alzheimer’s disease downstream of Aβ toxicity, including reduction of mitochondrial oxidative stress and excitotoxicity, improvement of autophagic pathway function, and attenuation of tau hyperphosphorylation.

  • In March 2024, Athira presented new clinical and preclinical data further highlighting the therapeutic potential of fosgonimeton at the AD/PD™ 2024 International Conference on Alzheimer’s and Parkinson’s Diseases and Related Neurological Disorders.

    • Results from the exploratory SHAPE Phase 2 clinical trial in Parkinson’s disease dementia and dementia with Lewy bodies indicated a favorable safety and tolerability profile for fosgonimeton in trial participants. In addition, changes in ADAS-Cog13 observed in the fosgonimeton 40 mg dose arm were suggestive of a pro-cognitive effect, which was assessed for fosgonimeton for the first time in these disease states.

    • In Alzheimer’s preclinical disease models, results showed the neuroprotective effects of fosgonimeton against glutamate toxicity in vitro are driven, in part, by activation of pro-survival signaling pathways that may help to counteract neurodegenerative hallmarks of disease such as tau pathology and mitochondrial dysfunction.

    • In Parkinson’s preclinical disease models, results highlighted the ability of fosgonimeton to mitigate pathological alterations associated with α-synuclein toxicity in vitro and in vivo.

    • In an aged mouse preclinical model of Parkinson’s disease that included α-synuclein pathology and GBA1 inhibition, fosgonimeton improved motor function, promoted dopaminergic neuron survival, reduced α-synuclein aggregation, and protected against microglial activation.

  • In February 2024, Athira published research highlighting the neuroprotective and anti-inflammatory effects of ATH-1105 in preclinical models of ALS in the peer-reviewed journal, Frontiers in Neuroscience. The original research article is titled: “ATH-1105, a small-molecule positive modulator of the neurotrophic HGF system, is neuroprotective, preserves neuromotor function, and extends survival in preclinical models of ALS.”

  • All presentations and publications can be accessed on the Athira website at Medical Affairs – Athira Pharma.
