Brief Summary:
The study will evaluate the effect of Clarithromycin on the pharmacokinetics (PK) of LY2216684 in healthy participants. Side effects will be documented. There will be 2 study periods (5 and 9 days) and follow up will occur at least 7 days after the last dose. Screening is required within 45 days prior to the start of the study.

Arm Intervention/treatment
Experimental: LY2216684 + Clarithromycin
Participants will receive a single 18 mg oral dose of LY2216684 on Days 1 and 10. Clarithromycin (500 mg) will be administered twice a day (BID) on Days 6 through 13.
Drug: LY2216684
Administered orally
Drug: Clarithromycin
Administered orally

Primary Outcome Measures :
  1. Pharmacokinetics: Area under the plasma concentration-time curve from time 0 to infinity (AUC0-∞) of LY2216684 [ Time Frame: Up to 96 hours post administration of study drug (Day 1 and Day 10) ]
  2. Pharmacokinetics: Maximum plasma concentration (Cmax) of LY2216684 [ Time Frame: Up to 96 hours post administration of study drug (Day 1 and Day 10) ]
  3. Pharmacokinetics: Time to maximum plasma concentration (tmax) of LY2216684 [ Time Frame: Up to 96 hours post administration of study drug (Day 1 and Day 10) ]
