Cassava Sciences announced that clinical results of its Phase 2b study of sumifilam have been selected as a late-breaking oral presentation by the 13th international conference on Clinical Trials on Alzheimer's Disease (CTAD). CTAD is a prestigious annual conference focused on Alzheimer's research and development and takes place this year as a virtual event on November 4-7th, 2020. Members of CTAD's scientific committee select research abstracts for late-breaking, oral presentation based on medical and scientific significance, quality of data and methodology. Details of Late-breaking Presentation: Title: "Sumifilam Significantly Improves Eleven CSF Biomarkers in A Randomized, Placebo-Controlled, One-Month Clinical Trial in Alzheimer's Disease Patients." Cassava Sciences recently announced final results of a Phase 2b study with sumifilam, its lead drug candidate, in Alzheimer's disease. In a clinical study funded by the National Institutes of Health, Alzheimer's patients treated with 50 mg or 100 mg of sumifilam twice-daily for 28 days showed statistically significant improvements in biomarkers of disease pathology, neurodegeneration and neuroinflammation, versus Alzheimer's patients who took placebo. In addition, Alzheimer's patients treated with sumifilam showed improvements in validated tests of episodic memory and spatial working memory, versus patients on placebo. Cognitive improvements correlated most strongly with decreases in levels of P-tau181. A small, well-controlled study of sumifilam showed promising treatment effects in patients with mild-to-moderate Alzheimer's disease. In this study, sumifilam treatment over 28 days improved an entire panel of validated biomarkers of Alzheimer's disease, decreased measurements of neuroinflammation, showed a 98% responder rate, was safe and well-tolerated, and appears to benefit cognition. Importantly, the data are consistent with prior clinical and preclinical results, the drug's mechanism of action and over 10 years of basic research.
