结局指标
主要结局
Wake After Sleep Onset (WASO) With LY2624803 Compared to Placebo
时间窗: 8 hours in Periods 1, 2 and 3
WASO was calculated as total time in awake epochs between sleep onset time (first stage 2 epoch) and the end of the primary recording period (8 hours after lights -off). Data presented are Geometric Least Squares (LS) means. Geometric LS mean was calculated using mixed models analysis. The model included factors for treatment, treatment sequence, period and participants.
次要结局
- Latency to Persistent Sleep (LPS)(8 hours in Periods 1, 2 and 3)
- Total Sleep Time (TST)(8 hours in Periods 1, 2 and 3)
- PK: Maximum Plasma Concentration (Cmax) of LY2624803 After Single Oral Dose in Period 4(Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 8, 10, 12, 18, and 42 hours post-dose in Period 4)
- PK: Area Under the Concentration-Time Curve From Time 0 to Infinity [AUC(0-∞)] of LY2624803 After Single Oral Dose in Period 4(Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 8, 10, 12, 18, and 42 hours post-dose in Period 4)
