Summary

The purpose of this study is to examine the effect of buprenorphine on QT interval corrected for heart rate (QTc) in healthy subjects.

Eligibility Criteria

Inclusion Criteria

  • Males and females 18 to 55 years of age, inclusive.
  • Body weight ranging from 50 to 100 kilograms (kg) and a body mass index (BMI) ≤ 30 kg/m2.
  • Healthy as determined by unremarkable medical history, physical examination, vital signs, laboratory evaluations, electrocardiogram (ECG), and a 24-hour screening ECG telemetry.
  • Willing to refrain from strenuous exercise or contact sports during the study.
  • Female subjects must be surgically sterile or at least 2 years postmenopausal, or using an effective contraceptive method (intrauterine device, hormonal contraceptive, or double-barrier method).

Exclusion Criteria

  • Any clinically significant illness during the 30 days prior to randomization.
  • Any history of allergy to buprenorphine, any excipient of BTDS, opioids, psychotropic or hypnotic drugs, and/or moxifloxacin or any member of the quinolone class of drugs.
  • A clinically significant history of allergic reaction to wound dressings or bandages.
  • Any medical or surgical conditions which might interfere with drug absorption (transdermal or gastrointestinal), distribution, metabolism, or excretion.
  • Abnormalities on physical examination, vital signs, ECG, or clinical laboratory values, unless those abnormalities are judged to be clinically insignificant by the Investigator.
  • Any cardiovascular disorders, including hypertension.
  • Oxygen saturation (SpO2) ≤ 94% as measured by pulse oximetry.
  • Any personal or family history of prolonged QT interval or disorders of cardiac rhythm.
  • Abnormal cardiac condition denoted by any of the following:
  • QT interval ≥ 450 milliseconds (msec).
  • PR interval > 240 msec or ≤ 110 msec.
  • Evidence of second- or third-degree atrioventricular (AV) block.
  • Pathological Q-waves (defined as Q-wave > 40 msec or depth > 0.5 mV).
  • Evidence of ventricular preexcitation, complete left bundle branch block, right bundle branch block (RBBB), or incomplete RBBB.
  • A resting heart rate outside the range of 50 to 85 beats per minute (bpm).

Other protocol-specific exclusion/inclusion criteria may apply.
