Disposition of 14C-LY3009104 Following Oral Administration in Healthy Human Subjects

Study Overview
=================
Brief Summary
-----------------
This is a single dose study of radiolabeled [14C]-LY3009104 in healthy male volunteers to study the absorption, distribution, metabolism, and elimination of LY3009104. This study requires minimum of 7 days and maximum of 22 days stay. This study is for research purposes only and is not intended to treat any medical condition.

For abnormal values a single repeat will be allowed 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 Show evidence of significant active neuropsychiatric disease and in particular evidence of significant medical or psychiatric illness within the past 12 months Have known substance dependence or abuse within 6 months prior to the study (according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition [DSM-IV] diagnosis), or 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 Evidence hepatitis B (active or surface antigen positive [HBsAg+]) or hepatitis B core antibody positive, hepatitis B surface antibody negative (HBcAb+, HBsAb-) Use of prescription medication; over-the-counter medication; or herbal preparations containing St. John's Wort, kava, garlic, ginger, gingko biloba, or guarana within 14 days prior to admission Consumption of grapefruit or grapefruit-containing foods or juices within 7 days prior to dosing or at any time during the study Have an average weekly alcohol intake that exceeds 15 units per week, or are unwilling to stop alcohol consumption for the duration of the study (1 unit = 12 oz or 360 milliliter (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 of comparable caffeine content) per day, on a habitual basis, or any subjects unwilling to adhere to study caffeine restrictions (no caffeine 48 hours prior to admission until the end of study Use of tobacco or nicotine-replacement products within the 6 months prior to study entry or at any time during the study Have donated blood of more than 500 mL within the last month Have participated in a 14C-study within the last 6 months prior to Check-in for this study. The total exposure from this study and the previous study must be within the Code of Federal Regulations (CFR) recommended levels considered safe (per 21 CFR 361.1), for example less than 5,000 millirem (mrem)/year whole body annual exposure Exposure to significant radiation within 12 months prior to dose (for example, serial X-ray or computed tomography scans, barium meal, current employment in a job requiring radiation exposure monitoring)
