Single Dose Study in Healthy Participants to Investigate the Safety and Absorption of LY2584702

Study Overview
=================
Brief Summary
-----------------
This is a single-centre, placebo-controlled, two-part study in healthy participants. Part A will be a single dose, single period, placebo-controlled pilot study to explore the safety, tolerability, absorption and pharmacodynamic [effect of drug on a biological marker-phospho-S6 (pS6) levels in skin biopsies] of a single dose of 25 milligrams (mg) LY2584702 Reference formulation (RF). Part B is a single dose, placebo-controlled, 4-period crossover study to primarily evaluate the absorption of the Test Formulation (TF) in comparison with the (RF) of LY2584702.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetics: Maximum Observed Plasma Concentration (Cmax) | The Cmax following a single oral dose of LY2584702 test formulation [TF (tablet)] or reference formulation [RF (capsule)] is reported. | Part A: Day 1 and Part B: Periods 1 to 4, Day 1 [Predose, 1 hour (h), 3 h, 4 h, 6 h, 10 h, 24 h, 48 h postdose] | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetics, Area Under the Concentration-Time Curve (AUC) | AUC from time 0 to the time of the last quantifiable concentration [AUC(0-tlast)] and AUC from time 0 to infinity [AUC(0-inf)] following a single oral dose of LY2584702 test formulation [TF (tablet)] or reference formulation [RF (capsule)] is reported. | Part A: Day 1 and Part B: Periods 1 to 4, Day 1 [Predose, 1 hour (h), 3 h, 4 h, 6 h, 10 h, 24 h, 48 h postdose] | 
| Part B: Baseline-Adjusted Change-From-Predose in the Concentration of Lipids (Total Cholesterol) | Baseline-adjusted change-from-predose in lipid concentrations were measured to assess the LY2584702 effect on lipids under different fed states. The 50-milligram (mg) LY2584702 test formulation [TF (tablet)] was the only dose and formulation administered in both the fasted and fed states for comparison. Therefore, changes in total cholesterol after single oral doses of placebo, 10-mg, or 200-mg LY2584702 TF or 25-mg or 50-mg LY2584702 reference formulation [RF (capsule)] were not calculated. The baseline-adjusted change-from-predose in total cholesterol levels in the fasted and fed state following a single 50-mg LY2584702 TF dose is reported. Baseline was Day -1 of Period 1 for Period 3 fasted state and baseline was Day -1 of Period 4a for Period 4a fed state. Least squares (LS) means was calculated using mixed model repeating measures (MMRM) and adjusted for treatment, time, treatment by time, and participant. | Part B: Baseline [Periods 1 and 4a (Day -1)], Periods 3, 4a (Day 1). Lipid concentration measurements were performed at time point 0 and 1 hour (h), 3 h, 4 h, 6 h, 10 h, and 24 h. | 
| Part A: QT Interval Corrected by Fridericia's Formula (QTcF) Change From Baseline to Day 1 | The QT interval is a measure of the time between the start of the Q wave and the end of the T wave and is calculated from electrocardiogram (ECG) data. Corrected QT (QTc) is the QT interval corrected for heart rate and RR, which is the interval between 2 R waves. Using Fridericia's formula: QTcF = QT/RR^0.33. The QTcF after single oral doses of LY2584702 reference formulation [RF (capsule)] were administered in a fasted state are reported at baseline (Day 1, Predose) and 3 hours (h), 4 h, 6 h, and 24 h postdose. | Part A: Baseline [Day 1 (Predose)] and Day 1 (3 h, 4 h, 6 h, and 24 h postdose) | 
| Part B: Average Time-Matched QT Interval Corrected by Fridericia's Formula (QTcF) Change From Baseline to Day 1 | The QT interval is a measure of the time between the start of the Q wave and the end of the T wave and is calculated from electrocardiogram (ECG) data. Corrected QT (QTc) is the QT interval corrected for heart rate and RR, which is the interval between 2 R waves. Using Fridericia's formula: QTcF = QT/RR^0.33. The QTcF after single oral doses of LY2584702 test formulation [TF (tablet)], LY2584702 reference formulation [RF (capsule)], or placebo were administered in a fasted or fed state are reported at baseline (time-matched Day -1 QTcF) and 3 hours (h), 4 h, 6 h, and 24 h postdose. Day 1, Hour 24 was time-matched with Day-1, Hour 0. | Part B: Baseline [Period 1 (Day -1)] and Periods 1 to 4 (Day 1). Electrocardiograms (ECG) were performed at time point 0 and 3 h, 4 h, 6 h, and 24 h. |
