Brief Summary:

The purpose of this study is to measure if there is any difference in how the body breaks down or inactivates either fluoxetine or LY2216684 when both of these medicines are given together. This study will look at how fluoxetine might affect LY2216684 and how giving LY2216684 might affect fluoxetine in the body.

The duration of study participation in this study is approximately 36 days not including the screening appointment. This study requires 1 research unit confinement of 29 days/28 nights followed by 1 outpatient appointment. A screening appointment is required within 30 days prior to the start of the study.

Fluoxetine: 60 mg po QD for 7 days (Days 4-10) then 20 mg po QD for 17 days (Days 11-27)

Drug: LY2216684
LY2216684: 18 mg po QD on Days 1, 2, and 3 and Days 25-27

Fluoxetine: 60 mg po QD for 7 days (Days 4-10) then 20 mg po QD for 17 days (Days 11-27)




Primary Outcome Measures :
  1. Pharmacokinetic (PK) Parameter: Area Under the Plasma Concentration-Time Curve Over a 24-Hour Dosing Interval (AUCτ) of LY2216684 [ Time Frame: Predose and 1, 2, 3, 4, 6, 8, 12, and 24 hours post-dose on Days 3 and 27 ]
    The Least Squares (LS) geometric mean AUCτ of LY2216684 was calculated based on the LY2216684 plasma concentration time curve from time 0 hour (hr) to time 24 hr (tau [τ]) when LY2216684 was administered alone (Day 3) and when LY2216684 was coadministered with fluoxetine (Day 27). The Day 27-to-Day 3 ratio of the LY2216684 LS geometric mean of AUCτ and the associated 90% confidence interval (CI) of the ratio were calculated.

  2. Pharmacokinetic (PK) Parameter: Maximum Plasma Concentration (Cmax) of LY2216684 [ Time Frame: Predose and 1, 2, 3, 4, 6, 8, 12, and 24 hours post-dose on Days 3 and 27 ]
    The Least Squares (LS) geometric mean Cmax of LY2216684 was determined when LY2216684 was administered alone (Day 3) and when LY2216684 was coadministered with fluoxetine (Day 27). The Day 27-to-Day 3 ratio of the LY2216684 LS geometric mean of Cmax and the associated 90% confidence interval (CI) of the ratio were calculated.

  3. Pharmacokinetic (PK) Parameter: Time to Maximum Plasma Concentration (Tmax) of LY2216684 [ Time Frame: Predose and 1, 2, 3, 4, 6, 8, 12, and 24 hours post-dose on Days 3 and 27 ]
    Tmax of LY2216684 was determined using the median of paired differences between the 2 treatment groups when LY2216684 was administered alone (Day 3) and when LY2216684 was coadministered with fluoxetine (Day 27). The 90% confidence interval (CI) for the median of differences was calculated.


Secondary Outcome Measures :
  1. Pharmacokinetic (PK) Parameter: Area Under the Plasma Concentration Time-Curve Over a 24-Hour Dosing Interval (AUCτ) of Fluoxetine and Norfluoxetine [ Time Frame: Predose and 1, 2, 3, 4, 6, 8, 12, and 24 hours post-dose on Days 24 and 27 ]
    The Least Squares (LS) geometric means AUCτ of fluoxetine and norfluoxetine were calculated based on the fluoxetine and norfluoxetine plasma concentration time curves from time 0 hour (hr) to time 24 hr (tau [τ]) when fluoxetine was administered alone (Day 24) and when fluoxetine was coadministered with LY22166684 (Day 27). The Day 27-to-Day 24 ratios of fluoxetine and norfluoxetine LS geometric means of AUCτ and the associated 90% confidence interval (CI) of the ratios were calculated.

  2. Pharmacokinetic (PK) Parameter: Maximum Plasma Concentration (Cmax) of Fluoxetine and Norfluoxetine [ Time Frame: Predose and 1, 2, 3, 4, 6, 8, 12, and 24 hours post-dose on Days 24 and 27 ]
    The Least Squares (LS) geometric means Cmax of fluoxetine and norfluoxetine were determined when fluoxetine was administered alone (Day 24) and when fluoxetine was coadministered with LY2216684 (Day 27). The Day 27-to-Day 24 ratios of fluoxetine and norfluoxetine LS geometric means of Cmax and the associated 90% confidence interval (CI) of the ratios were calculated.

  3. Pharmacokinetic (PK) Parameter: Time to Maximum Plasma Concentration (Tmax) of Fluoxetine and Norfluoxetine [ Time Frame: Predose and 1, 2, 3, 4, 6, 8, 12, and 24 hours post-dose on Days 24 and 27 ]
    Tmax of fluoxetine and norfluoxetine was determined using the median of paired differences between the 2 treatment groups when fluoxetine was administered alone (Day 24) and when fluoxetine was coadministered with LY2216684 (Day 27). The 90% confidence interval (CI) for the median of differences was calculated.
