- Healthy Male Volunteers
- Interventions
- Radiation: Drug
- Registration Number
- NCT01577355
- Lead Sponsor
- Eli Lilly and Company
- Brief Summary
This is a single dose study of radiolabelled LY2784544 in healthy male subjects to study the absorption, distribution, metabolism and excretion of LY2784544. This study is for research purposes only and is not intended to treat any medical condition.
- Detailed Description
This study is approximately 10 days long, (minimum 5 days, maximum 15 days) not including screening or follow up. Screening is required within 28 days prior to the first dose of study drug and follow up is required at least 7 days after discharge from the clinical research unit.

-
Have a body mass index (BMI) of 19 to 29 kg/m^2, inclusive

-
Have given written informed consent approved by Lilly and the institutional review board (IRB) governing the CRU
- Are currently enrolled in, have completed, or discontinued within the last 30 days from a clinical study 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 LY2784544 or related compounds
- Have previously completed or withdrawn from this study or any other study investigating LY2784544
- 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 a history or evidence of significant active neuropsychiatric disease and in particular evidence of significant medical or psychiatric illness within the past 12 months or have suicidal risk at the time of screening in the opinion of the investigator
- Have any other condition that in the opinion of the investigator would preclude participation in the study
- 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
- Use of herbal preparations containing St. John's Wort, kava, garlic, ginger, gingko biloba, or guarana within 14 days prior to admission or at any time during the study
- Intent to use over-the-counter (OTC) medication or prescription medication within 7 days prior to dosing or at any time during the study
- Consumption of grapefruit or grapefruit-containing foods or grapefruit-containing juices, Seville oranges or Seville orange juices, and star fruit or star fruit juices within 7 days prior to dosing or at any time during the study
- Have an average weekly alcohol intake that exceeds 21 units per week or are unwilling to stop alcohol consumption for the duration of 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 admission 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), less than 5000 millirems (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)
- Are currently smokers or users of tobacco or nicotine-replacement products within the 6 months prior to study entry
- Baseline 12-lead electrocardiogram (ECG) with a corrected QT (Bazett's) interval of >450 msec and/or have an abnormality in the 12-lead ECG that, in the opinion of the investigator, increases the risks associated with participating in the study
- Regularly use known drugs of abuse and/or show positive findings on urinary drug screening
- Have a history of congestive heart failure, unstable angina, myocardial infarction, or documented history of ventricular arrhythmia
- Gastrointestinal disorders causing clinically significant symptoms such as nausea, vomiting, and diarrhea, or malabsorption syndromes
- Evidence of active renal disease (e.g., diabetic renal disease, polycystic kidney disease) or creatinine clearance (CrCl) less than 70 mL/min
- Urinalysis with ≥1+ protein or ≥1+ blood (unless attributable to an acute condition that is resolved prior to dosing)
- Use of drugs with narrow therapeutic windows and that are also known substrates of Cytochrome P450 (CYP)1A2, CYP2B6, and CYP3A are specifically excluded
- Use of antacids and proton pump inhibitors
- Typically do not produce at least one bowel movement per day
