Cassava Sciences (SAVA) shares plummeted in premarket trading, shedding 80% of their value after the biotech firm announced the failure of its Alzheimer’s drug Simufilam in a critical late-stage trial.
The drug, targeting mild-to-moderate Alzheimer’s disease, showed no significant impact on cognitive or functional decline during the Phase 3 study, reported Investopedia.
The disappointment reverberates across the Alzheimer’s community, with Cassava CEO Rick Barry expressing regret for patients, families, and physicians seeking new treatment options. Barry noted that cognitive loss in the placebo group was unexpectedly lower than in prior studies, compounding the trial’s challenges.
Following the trial failure, Cassava plans to halt its other late-stage and open-label studies for Simufilam.
Open-label studies, where both patients and providers are aware of treatments being administered, were among the approaches the company hoped would yield positive results.
The setback further tarnishes Cassava’s reputation.
In September, it settled a $40 million charge with the SEC over alleged manipulation of trial data related to its Alzheimer’s drug.
Despite an earlier surge in stock performance this year, the dramatic drop brings Cassava’s year-to-date gains down to 18%. Investors and analysts now question the company’s future direction in the competitive biotech landscape.
The failure underscores the persistent difficulty in developing effective Alzheimer’s treatments, a field marked by numerous high-profile setbacks. For Cassava, the focus shifts to reassessing its pipeline and strategy amid mounting pressure.
This latest chapter in Cassava’s tumultuous journey serves as a stark reminder of the challenges inherent in Alzheimer’s research, a pursuit fraught with both scientific and financial risks.
