Study summary

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.

Read the detailed description

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.

What researchers measure

Primary outcomes

  1. 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.

    Time frame: Predose to 10-14 days after final dose of study drug (up to 42 days)

Secondary outcomes

  1. Maximum Observed Plasma Concentration (Cmax) of LY2886721

    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 the other LY2886721 groups received LY2886721 in the fasted state. Due to the crossover design in Part 1, results are reported by treatment; therefore, participants are included in multiple arms.

    Time frame: 0, 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 60 and 96 hours post-dose

  2. Plasma Concentration of LY2886721: Area Under the Concentration Versus Time Curve (AUC)

    Pharmacokinetic AUC for LY2886721 from time 0 to infinity. 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 the other LY2886721 groups received LY2886721 in the fasted state.
