Primary purpose: TREATMENT

Brief summary: The study involves a single oral dose of 18 mg (2 x 9mg tablets) LY2216684 taken on 2 occasions, once with activated charcoal and once without activated charcoal.

The study will evaluate the effect of charcoal on the absorption of LY2216684. Side effects will be documented. There will be 2 study periods each lasting up to 5 days. There will be at least 7 days between the two doses and a follow up will occur at least 7 days after the last dose. Screening is required within 30 days prior to the start of the study.


Eligibility criteria: Inclusion Criteria:

* Are overtly healthy, as determined by medical history and physical examination

  - Male subjects: Agree to use a reliable method of birth control during the study and for 1 month following the last dose of the study drug

  - Female subjects: Are women of child-bearing potential who test negative for pregnancy at the time of enrollment, have used a reliable method of birth control 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 \[FSH\] \>40 mIU/mL \[milli-international-units/milliliter\])
* Have a body weight \>50 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

* Are reliable and willing to make themselves available for the duration of the study and are willing to follow study procedures
* Have given written informed consent approved by Lilly and the institutional review board (IRB) governing the site
* Have normal blood pressure (BP) and pulse rate (sitting position)

Exclusion Criteria:

* Are currently enrolled in, have completed or discontinued within the last 30 days from, a clinical trial involving an investigational product other than the investigational product used in this study; 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, related compounds, or any components of the formulation
* Are persons who have previously received the investigational product in this study, have 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 or show evidence of significant active neuropsychiatric disease or have a history of suicide attempt or ideation
* Have a documented or suspected history of glaucoma
* 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 who are lactating
* Intend to use over-the-counter or prescription medication within 14 days prior to dosing unless deemed acceptable by the investigator and Sponsor's medical monitor. Exceptions include influenza vaccinations, the use of topical medication (provided there is no evidence of chronic dosing with the risk of systemic exposure), occasional use of acetaminophen/paracetamol/ibuprofen, hormone replacement therapy including thyroid replacement (stable dose for at least 1 month), and stable doses (at least 1 month) of oral contraceptive therapy
* Have donated blood of more than 500 mL (milliliter) within the last month
* Have an average weekly alcohol intake that exceeds 21 units per week (males) or 14 units per week (females), or are unwilling to stop alcohol consumption from 48 hours prior to dosing in each period until discharge in each period (1 unit = 12 oz \[ounces\] or 360 mL of beer; 5 oz or 150 mL of wine; 1.5 oz or 45 mL of distilled spirits)
* Consume 5 or more cups of coffee (or other beverages or foods of comparable caffeine content) per day, on a habitual basis, or are unwilling to stop caffeine consumption from 48 hours prior to dosing in each period until discharge in each period
* Subjects unwilling to adhere to the smoking restrictions of the Clinical Research Unit (CRU) while a resident of the CRU.
* Have consumed grapefruit or grapefruit-containing products 7 days prior to enrollment or are unwilling to avoid them during the study
* Subjects determined to be unsuitable by the investigator for any reason
