Brief summary

The study involves a single oral dose of 18 mg (2 x 9mg tablets) LY2216684 taken on 2 occasions, once with activated charcoal and once without activated charcoal. The study will evaluate the effect of charcoal on the absorption of LY2216684. Side effects will be documented. There will be 2 study periods each lasting up to 5 days. There will be at least 7 days between the two doses and a follow up will occur at least 7 days after the last dose. Screening is required within 30 days prior to the start of the study.

Overall
During Study Period 1, participants received a single oral dose of 18 mg LY2216684 alone or in combination with 1 g/kg Activated Charcoal 1 hour after LY2216684 administration. After at least 7 days, participants who initially received 18 mg LY2216684 alone received another single oral dose of 18 mg LY2216684 in combination with 1 g/kg Activated Charcoal 1 hour after LY2216684 administration during Study Period 2; participants who initially received 18 mg LY2216684 in combination with 1 g/kg Activated Charcoal received another single oral dose of 18 mg LY2216684 alone during Study Period 2.

Primary

Pharmacokinetics: Area Under the Plasma Concentration-Time Curve From Time 0 to Infinity (AUC0-∞) of LY2216684

The AUC0-∞ of LY2216684 was measured. The AUC was calculated for LY2216684 administered alone (reference) and LY2216684 co-administered with charcoal (test). Geometric Least Squares (LS) means were calculated according to the following model: Log(PK) = sequence + period + treatment + subject + random error for AUC.

Time frame: Predose, up to 72 hours after administration of study drug

Population: All participants who were randomized, for whom AUC0-∞ data were available, and who were not excluded due to vomiting within twice the median time to maximum plasma concentration (tmax) of LY2216684.
