Read MoreHide Full Article

Cassava Sciences, Inc. (SAVA - Free Report) announced that it has initiated the first initial phase III efficacy study evaluating its investigational drug candidate, simufilam, for the treatment of patients with Alzheimer’s disease (“AD”).

The first double-blind, placebo-controlled phase III study, RETHINK-ALZ, will evaluate the safety and efficacy of simufilam (100 mg) in enhancing cognition and slowing cognitive and functional decline, over a period of 52 weeks. The study will enroll around 750 patients with mild-to-moderate AD in the United States, Canada and other countries worldwide.

The second double-blind, placebo-controlled phase III study, REFOCUS-ALZ, will evaluate the safety and efficacy of simufilam (100 mg and 50 mg) over a period of 78 weeks. The study is expected to begin by 2021-end and will enroll around 1000 patients with mild-to-moderate AD.

We note that both the above phase III efficacy studies are being conducted under the FDA’s Special Protocol Assessments (“SPA”). In August 2021, Cassava reached an agreement with the FDA on SPA for its phase III studies of simufilam for the treatment of AD.

Shares of Cassava have skyrocketed 670% so far this year against the industry’s decrease of 16.7%.

Last month, Cassava announced top-line data from an interim analysis of the ongoing study on simufilam for treating patients with mild-to-moderate AD. Data from the same showed that the first 50 subjects who completed one year of open-label treatment with simufilam saw their cognition scores improve at an average of 3.2 points on the Alzheimer’s Disease Assessment Scale–Cognitive Subscale (ADAS-Cog) from the baseline.

Simufilam is a proprietary, small-molecule (oral) drug that restores the normal shape and function of altered filamin A, a scaffolding protein, in the brain.

We note that, the FDA approval of Biogen’s (BIIB - Free Report) AD drug, Aduhelm (aducanumab), has put the spotlight on this promising yet challenging space. In June 2021, Biogen and its partner Eisai won the FDA approval for Aduhelm as the first and only AD treatment, after a few setbacks.

Some other companies are also working hard to get their AD drugs approved. Eli Lilly (LLY - Free Report) is developing investigational antibody therapy, donanemab, for AD. Annovis Bio, Inc. (ANVS - Free Report) is also developing its pipeline candidate, currently in a mid-stage study, for treating AD.
