A Clinical Study to Determine the Effect of YM178 on the Pharmacokinetics of Warfarin in Healthy Subjects
July 1, 2013 updated by: Astellas Pharma Inc
An Open-label, One-sequence Crossover Study to Evaluate the Effect of Multiple Doses of YM178 on the Pharmacokinetics of Warfarin in Healthy Subjects
This study investigates whether YM178 has an effect on the pharmacokinetics of warfarin, to exclude any drug-drug interaction between YM178 and warfarin, and evaluates the safety and tolerability of warfarin alone and combined with YM178.

Description
Inclusion Criteria:
- Female subject must be of non-child bearing potential, i.e. postmenopausal, surgically sterilized (e.g. tubal ligation), hysterectomy in medical history, or must practice adequate (double barrier) non-hormonal contraceptive methods to prevent pregnancies.
- Body Mass Index (BMI) ≥ 18.5 and < 30 kg/m2, inclusive
Exclusion Criteria:
- Female who is pregnant
- Any of the liver function tests (i.e. alanine aminotransferase (ALT), aspartate aminotransferase (AST) and Alkaline Phosphatase (AP)) above the upper limit of normal (ULN)
- Any clinically significant history of disease or disorder - gastrointestinal, cardiovascular, respiratory, renal, hepatic, neurological, dermatological, psychiatric or metabolic as judged by the medical investigator
- Abnormal pulse and/or blood pressure measurements and the pre-study as follows: Pulse < 40 or > 90 bpm; mean systolic blood pressure > 140 mmHg; mean diastolic blood pressure > 90 mmHg (blood measurements taken in triplicate after subject has been resting in supine position for 5 min; pulse will be measured automatically
- A marked baseline prolongation of QT/QTc interval after repeated measurements of >450 ms, a history of unexplained syncope, cardiac arrest, unexplained cardiac arrhythmias or torsades de pointes, structural heart disease, or a family history of Long QT Syndrome (LQTS)
- Use of any prescribed or OTC (over-the counter) drugs (including vitamins, natural and herbal remedies, e.g. St. John's wort) in the 2 weeks prior to admission to the Clinical Unit, except for paracetamol (up to 3 g/day)
- Any use of drugs of abuse within 3 months prior to admission to the clinical unit
- History of smoking more than 10 cigarettes (or equivalent amount of tobacco) per day within 3 months prior to admission to the clinical unit
- History of drinking more than 21 units of alcohol per week (1 unit = 270 ml of beer or 40 ml of spirits or 1 glass of wine) (> 14 units of alcohol for female subjects) within 3 months prior to admission to the clinical unit
- Donation of blood or blood products within 3 months prior to admission to the clinical unit
