Trial Outcomes & Findings for Food and Insulin Effect on QT/QTC Interval of ECG (NCT NCT01642485)

NCT ID: NCT01642485

Last Updated: 2014-08-20

Results Overview

The primary baseline corrections were calculated using averaged QTc baseline values (the mean of all median readings recorded for each time-point on the baseline Day -1). This single value (QTcbaselineAV) was used to calculate ΔQTc for each study period.

Measure
All Study Participants
n=32 Participants
Subjects participating in the study attended for screening, two treatment periods (periods 1 and 2) of 4 assessment days each and a follow-up visit. Data obtained on study days 1 and 2 compared the ECG effects of different types of food and placebo. Each period consisted of a baseline ECG day (day -1) and treatment days (days 1-3). Moxifloxacin was given in fasted condition or with Continental breakfast, on day 3 of each study period. The two periods were separated by at least 3 days to allow for the effects of moxifloxacin to wash-out. No wash-out was required between the other treatments investigated. The ECG and samples for PK and PD analysis on the treatment days were taken at the corresponding clock time points as on the baseline days. Each subject received all treatments and all the comparisons between treatment effects were made intra-individually reducing the anticipated variability and thereby reducing the sample size.

PRIMARY outcome

Timeframe: 0 (pre-dose), 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 3.5, 4 and 6 hours post-dose

Population: Since the baseline was used as a covariate in the analysis, using the standard deviation of the change from baseline, in the simple sample size formula is justified. Assuming a standard deviation of 7 msec for the single differences, sample sizes for the sum can therefore work with a standard deviation of 6.5 msec.

The primary baseline corrections were calculated using averaged QTc baseline values (the mean of all median readings recorded for each time-point on the baseline Day -1). This single value (QTcbaselineAV) was used to calculate ΔQTc for each study period.

This study was designed as an open-label, randomized, placebo-controlled, crossover trial that evaluated the effect of a 400 mg oral dose of moxifloxacin in fasted conditions to a baseline and a placebo treatment. Data obtained on study days 1 and 2 compared the ECG effects of different types of food and placebo. Each period consisted of a baseline ECG day (day -1) and treatment days (days 1-3). Moxifloxacin was given in either the fed or fasted condition, on day 3 of each study period. The two periods were separated by at least 3 days to allow for the effects of moxifloxacin to wash-out. The ECG and samples for PK and PD analysis on the treatment days were taken at the corresponding clock time points as on the baseline days.

Scott et al (2002) demonstrated an increase in the heart rate of 10bpm in some healthy subjects following ingestion of a carbohydrate meal. There was significant correlation between the resultant hyperinsulinaemia and an increase in skeletal muscle blood flow, and sympathetic activity, with a reduction in vascular resistance. If postprandial insulinaemia is a significant influence on the QT interval, then carbohydrate rich meals would be expected to show greater effect. Therefore, to explore this on two separate days of the study subjects will be given one of two different types of breakfast: 1. A high carbohydrate content breakfast, (\>70% carbohydrate) 2. A reduced calorie FDA standard breakfast, (58% fat, low carbohydrate content) to determine effect on QT interval.

The effect on QTc was investigated using linear mixed effect models with placebo corrected QTcF (change from average baseline) as a dependent variable and insulin, glucose and C-peptide (placebo corrected) as covariates for the data obtained under the euglycaemic clamp as well as for all data obtained under the clamp and the two types of breakfast.
