A Study to Evaluate the Effect of GSK1322322 on Cardiac Conduction as Assessed by 12-lead Electrocardiogram in Healthy Volunteers
2015年1月26日 更新者:GlaxoSmithKline
A Phase I, Randomized, Partially Blinded, Placebo- and Moxifloxacin-Controlled, 4-Period Crossover Study to Evaluate the Effect of GSK1322322 on Cardiac Conduction as Assessed by 12-lead Electrocardiogram in Healthy Volunteers (PDF112166)
This is a randomized, partially-blinded, placebo and moxifloxacin-controlled, single dose, 4-period, balanced crossover study.
The primary objective of this study is to separately assess the effects of a therapeutic and supratherapeutic dose of GSK1322322 on the cardiac conduction (corrected QT interval [QTc]) compared with placebo in eligible healthy male and female subjects.
Avelox (moxifloxacin hydrochloride) will be used as an open-label positive control in order to validate the sensitivity of the study in detecting QTc change.
Approximately 56 healthy subjects will participate in the study for approximately 9 weeks i.e. 30 day Screening period, 4-week Treatment period, and a 7-10 day Follow-up period.
There will be 4 treatment periods separated by at least 1 week.
Subjects will be admitted to the clinical unit on Day -1 of each dosing period.
Each subject will receive each of the four treatment sequences (GSK1322322 1200 milligram [mg] intravenous [IV] over 60 minutes x 1 dose, GSK1322322 3000 mg IV over 60 minutes x 1 dose, GSK1322322 Placebo IV over 60 minutes x 1 dose, moxifloxacin 400 mg administered orally x 1 dose) on Day 1 of each Treatment period in a randomized fashion.
Twelve-lead electrocardiogram (ECG), continuous Holter monitoring, laboratory tests, vital sign measurements, and serial pharmacokinetic samples will be collected for up to 24 hours following each treatment.
If no clinically significant abnormalities are noted, subjects will be discharged from the clinical research unit after the completion of all assessments on Day 2 in each period and return approximately one week later for the next dosing period.
Each individual subject will follow the same dosing schedule at every period.
A Follow-up visit will be conducted 7-10 days after administration of the last dose of study medication in treatment period 4.
