On Wednesday, Athira Pharma, Inc. (NASDAQ:ATHA) stock is trading lower after the company released topline results from its Phase 2/3 LIFT-AD clinical trial of fosgonimeton for mild-to-moderate Alzheimer’s disease (AD).
A -0.08 change in GST (the Global Statistical Test, a combination of results from measures of cognition (ADAS-Cog11) and function (ADCS-ADL23) favoring fosgonimeton that did not reach statistical significance (p=0.70)
The change in cognition from baseline, for which a decrease from baseline represents an improvement, was -0.39 for the placebo group and -1.09 for the fosgonimeton-treated group, a difference of -0.70 (p=0.35) favoring fosgonimeton.
In the fosgonimeton-treated group, function increased (improved) by 0.65 versus a decline of -0.02 in placebo, although this difference did not meet statistical significance (p=0.61).
In addition, data across protein pathology, inflammation, and neurodegeneration biomarkers showed directional improvements with fosgonimeton treatment.
“These are not the results we hoped for, as the lack of clinical decline in the placebo group, combined with the short duration of the study, may have impacted the trial’s ability to translate the effect of fosgonimeton treatment into meaningful clinical benefit,” said Javier San Martin, Chief Medical Officer of Athira.

In post hoc analysis by disease severity, fosgonimeton showed a larger effect size mainly driven by improved cognition at week 26.
