A Phase 1 interventional study of LY2886721 and Placebo in Alzheimer's Disease, sponsored by Eli Lilly and Company. Completed at 1 site in United States. Open to participants aged 20 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-09-16.
Sponsored by Eli Lilly and Company · Phase 1, Interventional, and Basic science
This is a Phase 1 study in healthy subjects to evaluate the safety and tolerability of LY2886721 single doses, how the body handles the drug, and the drug's effect on the body.
This is a Phase 1 study with 2 parts, both in healthy subjects. Part 1 is a subject- and investigator-blind, placebo-controlled, randomized, 3-period, crossover study. Part 1 will assess the safety and tolerability of LY2886721 single doses, how the body handles the drug, and the drug's effect on the body. Part 2 is a subject- and investigator-blind, placebo-controlled, randomized study to assess the safety and tolerability of an LY2886721 single dose, how the body handles the drug, and the drug's effect on the body including in cerebrospinal fluid.
3,678 studies on the registry are indexed under Alzheimer Disease; 872 are open to participants now.

Number of Participants With Clinically Significant Effects (Adverse Events)
A summary of serious adverse events and other nonserious adverse events located in Reported Adverse Event section. To assess effect of food on pharmacokinetics of LY2886721, participants in Cohort B during Period 3 (1 period=8 days) of Part 1 fasted overnight for at least 8 hours prior to receiving a single 7-milligram (mg) oral dose of LY2886721 in the fed state (Part 1 - Fed). Participants in other LY2886721 groups received LY2886721 in fasted state. Due to crossover design in Part 1, results reported by treatment; thus, participants are included in multiple arms.
