A Study of LY2216684 and Digoxin in Healthy Subjects

Effect of LY2216684 on the Pharmacokinetics of Digoxin in Healthy Subjects

The purpose of this study is to determine how much digoxin gets into the blood stream and how long it takes the body to get rid of it when given with LY2216684. Information about any side effects that may occur will also be collected.

• Female participants - Are women of child-bearing potential who test negative for pregnancy at the time of enrollment, have used a reliable method of birth control for 6 weeks prior to administration of study drug, and agree to use a reliable method of birth control during the study and for 1 month following the last dose of study drug; or Women not of child-bearing potential due to surgical sterilization (hysterectomy or bilateral oophorectomy or tubal ligation) or menopause (at least 1 year without menses or 6 months without menses and a follicle stimulating hormone [FSH] greater than (>) 40 milli-International Units/milliliter (mIU/mL).
• Have a body weight >50 kilograms (kg).
• 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 (potassium, magnesium, and calcium values must be within the normal range).

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

Exclusion Criteria:

• Are currently enrolled in, or discontinued within the last 30 days from, a clinical trial involving an investigational drug or device or off-label use of a drug or device other than the study drug, 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 LY2216684, digoxin, or related compounds.
• Are persons who have previously completed or withdrawn from this study or any other study investigating LY2216684 within 6 months prior to screening.
• Have an abnormality in the 12-lead electrocardiogram (ECG) that, in the opinion of the investigator, increases the risks associated with participating in the study.
• Have a history of or current 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 a history of significant dysrhythmias or atrioventricular (AV) block.
• Have a history or show evidence of significant active neuropsychiatric disease or have a history of suicide attempt or ideation.

• Are women with a positive pregnancy test or women who are lactating.
• Intend to use over-the-counter or prescription medication (including hormonal contraceptives) within 14 days prior to dosing unless deemed acceptable by the investigator and Sponsor's medical monitor, except for influenza vaccinations.
• Use of any drugs or substances that are known to be substrates, inducers, or inhibitors of P-glycoprotein (P-gp) and Cytochrome (P45) (CYP) within 30 days prior to dosing.
