Athira Pharma Presents Preclinical Data Supporting Therapeutic Potential of HGF/MET Platform at Neuroscience 2022 Conference

Fosgonimeton treatment showed results suggestive of neuroprotection and potential disease modification in models of Parkinson’s disease

Small molecule positive modulators of HGF/MET improved symptoms of diabetic neuropathy with a persistent response even following a washout period

BOTHELL, Wash., Nov. 16, 2022 (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, today announced data highlighting the potential therapeutic benefits of enhancing the HGF/MET neurotrophic system in preclinical models of Parkinson’s disease (PD) and diabetic neuropathy. These findings were presented at the Neuroscience 2022 conference, hosted by the Society for Neuroscience.

“Our studies continue to show that enhancing the HGF/MET pathway may have significant therapeutic benefit in various neuropathologies,” said Kevin Church, Ph.D., Executive Vice President, Research of Athira Pharma. “The data presented at Neuroscience 2022 show that fosgonimeton (ATH-1017) promotes neuroprotection, reduces alpha-synuclein aggregation in vitro, and improves motor performance in animal models of Parkinson’s disease.”

“We look forward to advancing the development of our pipeline and broadening our footprint in clinical neurobiology,” added Mark Litton, Ph.D., President and Chief Executive Officer of Athira.

An oral nanosymposium presentation highlighted the neuroprotective effects of fosgonimeton against neuronal damage and motor deficits in preclinical models of Parkinson’s disease. Study results show:

  • Rat cortical neurons incubated with fosgo-AM, the active metabolite of fosgonimeton, demonstrated significant improvement in neuronal survival over controls when exposed to neurotoxic insults implicated in neurodegeneration, including glutamate excitotoxicity, neuroinflammation, and oxidative stress.
  • Following exposure to neurotoxins, rotenone or 6-OHDA, rat dopaminergic neurons treated with fosgo-AM showed significantly increased protection of neuron numbers and the neurite network, as well as a reduction in alpha-synuclein aggregation (a protein pathology of PD) compared to controls.
  • In rats with 6-OHDA-induced striatal lesions, daily subcutaneous injections of fosgonimeton significantly improved motor function across several behavioral assessments.

A separate presentation described the effects of HGF/MET small molecule positive modulators in reducing pain-related behaviors in a preclinical model of diabetic neuropathy. Study results show:

  • Two small molecule positive modulators of the HGF/MET pathway, ATH-1018 and ATH-1020, significantly reduced measures of pain in a streptozotocin (STZ)-induced rat model of diabetic neuropathy.
  • Treatment with either ATH-1018 or ATH-1020 resulted in a sustained reduction of pain after a washout period of 23 hours. For ATH-1020 there was a sustained reduction of pain after a washout period of seven days.
  • The effects of these small molecules demonstrate the therapeutic potential for painful diabetic neuropathy.

About Fosgonimeton

Fosgonimeton is a small molecule designed to enhance the activity of hepatocyte growth factor (HGF) and its receptor, MET, to impact neurodegeneration and regenerate brain tissue. The function of the HGF/MET receptor system may be impaired in the brain under conditions of neurodegeneration. In addition to Alzheimer’s disease, fosgonimeton has the potential to address the broader dementia population, including Parkinson’s disease dementia and Dementia with Lewy bodies, as the mode of action focuses on network recovery and synaptic signal transmission in the brain.
