Rhea-AI Summary

Athira Pharma announced the completion of dosing for the last patient in their Phase 2/3 LIFT-AD clinical trial of fosgonimeton, aimed at treating mild-to-moderate Alzheimer's disease (AD). The trial involved approximately 315 patients, assessing the efficacy and safety of fosgonimeton through once-daily subcutaneous injections over a 26-week period. Athira plans to release topline results by the end of Q3 2024 and will present detailed data at the CTAD conference on October 29, 2024, in Madrid. The primary endpoint, the GST, evaluates changes in cognition and function using the ADAS-Cog11 and ADCS-ADL23 tests. The trial also includes serum biomarker analysis to explore the neuroprotective effects of fosgonimeton. Additionally, a significant portion of participants have enrolled in an open-label extension study, with over 70 patients continuing treatment beyond 18 months.

  • Completion of patient dosing in the LIFT-AD trial.
  • Topline results expected by the end of Q3 2024.
  • Presentation scheduled at CTAD on October 29, 2024.
  • High enrollment and retention in open-label extension study.
  • No concrete results or efficacy data yet available.
  • Potential uncertainty until topline results are reported.

The completion of patient dosing in the Phase 2/3 LIFT-AD clinical trial for Athira Pharma's fosgonimeton marks a significant milestone in Alzheimer's disease research. The choice of Global Statistical Test (GST) as the primary endpoint is noteworthy. GST combines measures of cognition (ADAS-Cog11) and function (ADCS-ADL23), both of which are well-established metrics in AD trials. By targeting both cognition and daily living activities, GST provides a comprehensive measure of the treatment's impact on the disease.

Another critical aspect is the measurement of serum biomarkers. These biomarkers can offer insights into the drug's neuroprotective mechanisms and its potential to modify the disease course. If the biomarkers reflect positive changes, it could bolster the case for fosgonimeton as a disease-modifying agent, setting it apart from symptomatic treatments currently available.

Investors should note the high long-term participation rates in the open-label extension study. Over 70 patients have continued treatment beyond 18 months and nearly 50 beyond two years. This suggests a favorable safety and tolerability profile, which is important for the drug's long-term commercial viability.

Athira Pharma's progress in the LIFT-AD trial for fosgonimeton should be seen within the broader context of the Alzheimer's disease treatment market. The market is highly competitive and has seen a surge in recent years with new drug approvals aimed at modifying the disease progression. Fosgonimeton's unique mechanism of action, which targets the neurotrophic hepatocyte growth factor (HGF) system, promises a novel approach. This differentiation could be a significant competitive advantage if the trial results are positive.

The ability to present topline results at a major conference like the Clinical Trials on Alzheimer’s Disease (CTAD) is strategically important. It provides a platform for visibility among key opinion leaders, potential investors and pharmaceutical partners. Positive outcomes from the trial could lead to increased interest and potential partnership opportunities, enhancing Athira's market position.

Investors should also consider the financial implications. Successful results could lead to an increase in the company's valuation, potential licensing deals and other forms of financial backing necessary for commercialization. However, the high stakes also mean that any negative results could significantly impact the stock price.

Reporting of Topline Results Targeted by End of Third Quarter 2024

Results to be presented in oral presentation at Clinical Trials on Alzheimer’s Disease (CTAD) on October 29, 2024, in Madrid, Spain

BOTHELL, Wash., July 09, 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, today announced the completion of dosing for the last patient in the Phase 2/3 LIFT-AD clinical trial evaluating fosgonimeton in people with mild-to-moderate Alzheimer’s disease (AD). The Company is now targeting to report topline results from the LIFT-AD trial by the end of the third quarter of 2024 and has been invited to discuss the fuller data set during an oral presentation on October 29, 2024, at the 17th Clinical Trials on Alzheimer’s Disease (CTAD) conference taking place from October 29 – November 1, 2024, in Madrid, Spain.
LIFT-AD (NCT04488419) is a randomized, placebo-controlled, double-blind study evaluating the efficacy and safety of fosgonimeton, which is designed to positively modulate the neurotrophic hepatocyte growth factor (HGF) system to protect and preserve neuronal health and function. The trial enrolled approximately 315 patients not on acetylcholinesterase inhibitors (AChEIs) with mild-to-moderate AD to evaluate once-daily subcutaneous injections of fosgonimeton 40 mg compared to placebo over a 26-week treatment period. The primary endpoint of LIFT-AD is the change from baseline after 26 weeks of treatment using the Global Statistical Test (GST), a combination of results from measures of cognition (ADAS-Cog11) and function (ADCS-ADL23).

“With patient dosing now complete, we eagerly look forward to the readout of topline results from the LIFT-AD trial, which is targeted by the end of September. The trial’s primary endpoint, GST, will assess the treatment effects of fosgonimeton across multiple aspects of the disease,” said Javier San Martin, M.D., Chief Medical Officer of Athira. “Both of the clinical assessments that comprise GST, ADAS-Cog11 and ADCS-ADL23, are widely used in AD trials and are accepted endpoints by the U.S. Food and Drug Administration and other regulatory bodies. Importantly, GST evaluates cognition and function, two key measures of disease progression, which gives us confidence that this endpoint will provide an understanding of the impact of relevant clinical outcomes that fosgonimeton may have in AD. Additionally, the trial will measure serum biomarkers, which will provide insights into the potential neuroprotective mechanism and disease modifying effects of fosgonimeton. We would like to extend our thanks to the investigators, their staff, patients and caregivers involved in the LIFT-AD trial.”

Notably, 85% of eligible clinical trial participants in LIFT-AD and the Phase 2 ACT-AD trial elected to enroll in Athira’s open label extension study (OLEX), which enables participants to either remain on fosgonimeton or, for those in the placebo group, begin fosgonimeton treatment. Currently, more than 70 patients are continuing fosgonimeton treatment beyond 18 months, with nearly 50 patients beyond two years, reflecting a long-term participation rate beyond what might be expected in a progressive mild-to-moderate Alzheimer’s disease population.

“We are excited to reach this milestone in the LIFT-AD trial and, more importantly, to be closer to data readout when we hope to demonstrate the potential of fosgonimeton as a differentiated approach to the treatment of Alzheimer’s disease,” said Mark Litton, Ph.D., President and Chief Executive Officer of Athira. “Patients are in need of better therapies, and we believe that fosgonimeton, acting on the naturally occurring neurotrophic HGF system, offers the potential to be a first-in-class therapeutic that may impact the course of Alzheimer’s disease by activating neuroprotective, neurotrophic and anti-inflammatory pathways in the central nervous system.”

Athira management recently hosted a Key Opinion Leader event focusing on GST, the primary endpoint of the LIFT-AD clinical trial, which Athira believes is a comprehensive measure of overall disease impact and the potential for fosgonimeton to protect and preserve neuronal health in mild-to-moderate AD patients. The webcast event featured presentations from Suzanne Hendrix, Ph.D., Founder and CEO of Pentara Corporation, and Anton P. Porsteinsson, M.D., Director of the University of Rochester Alzheimer’s Disease Care, Research, and Education Program (AD-CARE). A replay of the event can be accessed here.
