Clinical Trial Summary

Part A: The purpose of Part A of the study is to look at the electrocardiogram (ECG) effects due to blood sugar changes after a meal compared to when LY2409021 is also given with a meal.

Part B: The purpose of Part B is to evaluate the effect of LY2409021, when given at a dose level much higher than what would normally be given, on the electrical activity of the heart as measured by ECG in relation to placebo and moxifloxacin.

Description:

This is a 2 part study. Part A is a single-dose study to compare the effects of a meal on glucose, insulin and QT in healthy participants with and without LY2409021. Part B of this study is a randomized, 3-period, crossover design, in which participants and investigators are blinded to placebo and LY2409021, and will assess the electrophysiological effects of a single supratherapeutic dose of LY2409021 compared to a positive control (moxifloxacin) and placebo.

Eligibility

Inclusion Criteria:

• are overtly healthy males or females, as determined by medical history and physical examination

• have a clinically normal screening electrocardiogram (ECG) with a measurable QT interval as judged by central reader, which allows accurate measurements of QT interval

• 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 venous access sufficient to allow for blood sampling

• are reliable and willing to make themselves available for the duration of the study and are willing to follow study procedures

• have normal blood pressure and pulse rate (supine) at screening, or with minor deviations judged to be acceptable by the investigator

• have given written informed consent approved by Lilly and the ethical review board (ERB) governing the site

• serum magnesium and potassium equal to or above the lower limit of normal

Exclusion Criteria:

• are currently enrolled in or have completed or discontinued within the last 30 days (from screening) from a clinical trial involving an investigational product; or are concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study

• have known allergies to LY2409021, related compounds or any components of the formulations, or to moxifloxacin

• are persons who have previously received the investigational product in this study, have completed or withdrawn from this study or any other study investigating LY2409021

• personal or family history of long QT syndrome

• family history of sudden unexplained death or cardiac death in a family member under 60 years of age

• personal history of unexplained syncope within the last year

• 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

• regularly use known drugs of abuse and/or show positive findings on urinary drug screening

• show evidence of human immunodeficiency virus (HIV) infection and/or positive human HIV antibodies

• show evidence of hepatitis C and/or positive hepatitis C antibody

• show evidence of hepatitis B and/or positive hepatitis B surface antigen

• are women with a positive pregnancy test or women who are lactating

• intend to use over-the-counter (including mineral supplements and herbal medicine) or prescription medication within 7 days prior to dosing

• have donated blood of more than 500 milliliters (mL) within the last month

• have an average weekly alcohol intake that exceeds 21 units per week (males) and 14 units per week (females) (1 unit = 12 ounces [oz] or 360 mL of beer; 5 oz or 150 mL of wine; 1.5 oz or 45 mL of distilled spirits), or are unwilling to comply with alcohol restrictions during the study (that is, refrain from alcohol consumption from 24 hours prior to dosing until the completion of each treatment period and to consume no more than 2 units of alcohol per day between treatment periods)

• are participants who smoke more than 10 cigarettes per day and/or are unable to abide by the study restrictions for smoking/tobacco use (that is, refrain from smoking for approximately 2 hours prior to each ECG timepoint or for a total of approximately 12 hours)

• are participants who are unable to abide by the study restrictions for caffeine/xanthine use (that is, refrain from consuming caffeine/xanthine containing drinks and foods [such as coffee, tea, cola, and chocolate] on days on which ECGs are performed, and maintain consistent consumption habits on all other days of the study)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Part B: Mean Change From Baseline in 12-lead Electrocardiogram (ECG) Corrected QT Intervals (LY2409021)	The QT interval is a measure of the time between the start of the Q wave and the end of the T wave and was calculated from electrocardiogram (ECG) data using Fridericia's formula: QTc = QT/RR^0.33. Corrected QT (QTc) is the QT interval corrected for heart rate and RR, which is the interval between two R waves. Least Squares (LS) means were calculated using mixed effects model with fixed effects for treatment, time, period, sequence, and the time-by-treatment interaction, random effects for participant, the participant-by-treatment interaction, and participant-by-time interaction.	Baseline, 2, 4, 6, 8, 12, and 24 hours
Secondary	Part B: Mean Change From Baseline in 12-lead Electrocardiogram (ECG) Corrected QT Intervals (Moxifloxacin)	The QT interval is a measure of the time between the start of the Q wave and the end of the T wave and was calculated from electrocardiogram (ECG) data using Fridericia's formula: QTc = QT/RR^0.33. Corrected QT (QTc) is the QT interval corrected for heart rate and RR, which is the interval between two R waves. Least Squares (LS) means were calculated using mixed effects model with fixed effects for treatment, time, period, sequence, and the time-by-treatment interaction, random effects for participant, the participant-by-treatment interaction, and participant-by-time interaction.
