Cassava Sciences drops on delay for epilepsy study
Cassava Sciences' stock dropped ~14% premarket after announcing a delay in its epilepsy study for simufilam due to FDA concerns. The FDA has placed a full clinical hold on the study pending further information, including additional preclinical data. Cassava aims to address these concerns promptly but no longer expects to start the trial in H1 2026. The company has also phased out its Alzheimer's program for simufilam after a trial setback.
