A Study of LY2216684 in Major Depressive Disorder in Patients Taking Selective Serotonin Reuptake Inhibitors

Effect of LY2216684 on Ambulatory Heart Rate and Blood Pressure in Patients With Major Depressive Disorder Who Are Being Treated With Selective Serotonin Reuptake Inhibitors

The purpose of this study is to determine the effect of LY2216684 on heart rate and blood pressure in research participants with MDD who are being treated with an SSRI (selective serotonin reuptake inhibitors). Information about any side effects that may occur will also be collected. The duration of participation in this study is approximately 24 days not including the screening visit. This study requires 1 clinic confinement of 17 days/16 nights and 1 Follow-up Outpatient Visit. A screening visit is required within 30 days prior to the start of the study. In both periods 1 and 2, the study involves 4 single daily doses of 18 mg LY2216684 or placebo taken as 2 tablets by mouth. In period 3, the study involves four single daily doses of 36 mg LY2216684 or placebo taken as 4 tablets by mouth.

• Use of any drugs or substances that are known to be a strong inducer or inhibitor of cytochrome P450 2D6 (CYP2D6) or cytochrome P450 3A4 (CYP3A4) within 30 days prior to check-in (study entry) and during the conduct of the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum and Mean Change From Baseline in Ambulatory Heart Rate on Day 1	Heart rate was determined during ambulatory blood pressure monitoring (ABPM). Mean pre-dose ABPM values from Day 1 in Period 1 were used as baseline. Maximum and mean changes in ABPM heart rate were determined from a 24-hour continuous ABPM monitoring for Day 1 (0 to 24 hours). Least Squares (LS) mean changes from baseline were calculated with a mixed effects model including sequence, period, study day, treatment groups, and interaction between treatment groups and study day as fixed effects, and subject as random effect.	Baseline through the 24-hour interval on Day 1
Maximum and Mean Change From Baseline in Ambulatory Heart Rate on Day 4	Heart rate was determined during ABPM. Mean pre-dose ABPM values from Day 1 in Period 1 were used as baseline. Maximum and mean changes in ABPM heart rate were determined from 24 hour continuous ABPM monitoring for Day 4 (0 to 24 hours). LS mean changes from baseline were calculated with a mixed effects model including sequence, period, study day, treatment groups, and interaction between treatment groups and study day as fixed effects, and subject as random effect.
