A Study of LY3009104 in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
This will be a 2-part, randomized, participant- and investigator-blind study in healthy males and females. Part A of this study is to determine a safe and tolerable single oral dose of LY3009104 that yields drug exposures slightly exceeding typical exposures anticipated from repeated administration of an efficacious dose to participants. The concentration of the drug in the blood stream will be measured and information about any side effects that may occur will also be collected. Part B of this study is to evaluate the effect of LY3009104 on the electrical activity of the heart as measured by electrocardiogram (ECG) in relation to placebo following a single oral dose.

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Are overtly healthy males or females as determined by medical history and physical examination. Are drug free, disease free, and no cardiac abnormalities. Have clinical laboratory test results within normal reference range for the population or investigator site, or results with acceptable deviations that are judged to be not clinically significant by the investigator. Have a clinically normal screening ECG with a measurable QT interval as judged by the investigator, and which in Part B allows accurate measurements of QT interval. Exclusion Criteria: Have a history or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; of constituting a risk when taking the study medication; or of interfering with the interpretation of data. Have an abnormality in the 12-lead ECG that, in the opinion of the investigator, increases the risks associated with participating in the study or affects or confounds the corrected QT (QTc) analysis or have QTc greater than 450 milliseconds (msec). Regularly use known drugs of abuse and/or show positive findings on urinary drug screening.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline Through 24 Hours Postdose in Population-Corrected QT (QTcP) Interval | 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 the population-corrected formula: QTcP = QT/RR^beta, where beta is the population correction factor computed from a log-linear model (ln) QT = alpha+beta*ln RR fitted to all Day -1 and Day 1 predose QT and RR measurements in all periods for all participants. Baseline is the average of data collected for 2 hours before dosing on Day 1 of each period [-2 hours (h), -1.5 h, -1 h, -0.5 h, and 0 h]. The QTcP interval was not assessed during Part A of the study, as specified in the protocol. The QTcP interval at 1 h, 2 h, and 4 h postdose for moxifloxacin was compared to placebo to establish assay sensitivity. | Part B, Periods 1 through 3: Baseline, 1 h, 1.5 h, 2 h, 3 h, 4 h, 6 h, 12 h, and 24 h postdose | 
| Pharmacokinetics: Maximum Concentration (Cmax) of LY3009104 |  | Parts A and B, Periods 1 through 3: Predose and 0.5 hours (h), 1 h, 1.5 h, 2 h, 3 h, 4 h, 6 h, 12 h, 24 h, 36 h, 48 h after administration of study drug | 
| Pharmacokinetics: Area Under the Concentration Curve From Time 0 to Infinity [AUC(0-inf)] of LY3009104 |  | Parts A and B, Periods 1 through 3: Predose and 0.5 hours (h), 1 h, 1.5 h, 2 h, 3 h, 4 h, 6 h, 12 h, 24 h, 36 h, 48 h after administration of study drug | 
| Number of Participants With 1 or More Drug-Related Adverse Events (AEs) or Any Serious AEs (SAEs) | The number of participants with treatment-emergent adverse events (TEAEs) or treatment-emergent SAEs considered by the investigator to be related to study drug is reported. A summary of SAEs and other non-serious AEs regardless of causality is located in the Reported Adverse Events module. | Baseline through study completion and 30-day follow-up |
