The multinational, phase III EXPEDITION3 trial has examined more than 2,100 patients diagnosed with mild dementia due to Alzheimer's disease.
It includes an 18-month placebo-controlled period with a follow-on open label extension.
Results suggested that after being administered to patients, solanezumab did not result in a significant slowing in cognitive decline compared to patients treated with placebo determined on the basis of Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog).
Lilly president and CEO John Lechleiter said: "The results of the solanezumab EXPEDITION3 trial were not what we had hoped for and we are disappointed for the millions of people waiting for a potential disease-modifying treatment for Alzheimer's disease.
