While primary endpoints, both cognitive and functional, were not met in the two Phase 3, double-blind, placebo-controlled solanezumab EXPEDITION trials in patients with mild-to-moderate Alzheimer's disease, a pre-specified secondary analysis of pooled data in patients with mild Alzheimer's disease showed a statistically significant slowing of cognitive decline. This finding represented a 34 percent reduction in decline. Over the 18 months of the EXPEDITION studies, the difference between patients treated with solanezumab versus placebo increased at a relatively constant rate over time.
In the pooled analyses of the EXPEDITION studies, the only adverse event with an incidence of at least 1 percent that occurred statistically significantly more in the solanezumab group than in the placebo group was angina (1.1 percent versus 0.2 percent). The incidence of vasogenic edema (ARIA-E) was approximately 1 percent, occurring in 11 patients treated with solanezumab and 5 patients on placebo, which was not statistically significant.
An ongoing, open-label extension study, EXPEDITION-EXT, is fully enrolled and will continue as planned.
About Alzheimer's diseaseAlzheimer's disease, the most common form of dementia, causes progressive decline in memory and other aspects of cognition. 1,2 Researchers do not know exactly what causes Alzheimer's disease and there are currently no approved treatments shown to slow the progression of this devastating disease, only treatment options that reduce certain symptoms of the disease. 1,3,4 Alzheimer's Disease International (ADI) estimates that there are currently 35.6 million people with dementia worldwide, with 7.7 million new cases each year (which implies one new case every four seconds). 5 The number of people affected is estimated to be over 115 million by 2050. 4 Estimates vary, but experts suggest that as many as 5.4 million Americans may have Alzheimer's disease. 3About Eli Lilly and CompanyLilly, a leading innovation-driven corporation, is developing a growing portfolio of pharmaceutical products by applying the latest research from its own worldwide laboratories and from collaborations with eminent scientific organizations.
