Clinical Trial Summary

This is a single-center, partial-blind, randomized, placebo-controlled, parallel design study with a nested crossover comparison to define the ECG effects of tizanidine compared to placebo and the positive control, moxifloxacin, in healthy men and women. The study will be conducted in a Phase 1 unit with sufficient facilities to house subjects as required by the protocol.

Outcome

Type Measure Description Time frame Safety issue
Primary The Primary Endpoint Will be the Baseline-adjusted, Placebo-corrected Effect on QTc (??QTc) on Day 14. Change from baseline in Cardiac Repolarization (QTc Interval) at Day 14 (Tizanidine 24 mg). Moxifloxacin was not investigational drug, it was used to assess the sensitivity of the study. Baseline and Day 14
Secondary The Baseline-adjusted, Placebo-corrected (??QTc) on QTc Method Not Selected as Primary Endpoint. Change from baseline in Cardiac Repolarization (QTc Interval) at Day 5 (Tizanidine 8 mg). Moxifloxacin was not investigational drug, it was used to assess the sensitivity of the study. Baseline and Day 5
Secondary Assessing the Relationship Between Changes in the QTc Interval and Plasma Levels of Tizanidine Using Concentration-effect Modeling The relationship will be quantified using a linear mixed effects model with an intercept. Data from Day 5 and Day 14 were fitted into regression model to obtain a slope of change. The measure type 'Number' followed by (90% Confidence Interval) shown in results is the slope from the linear fit. Day 5, Day 14
Secondary Maximum Plasma Concentration (Cmax) of Single Doses of 8 and 24 mg Tizanidine After Reaching Steady State. 0.5, 1, 1.5, 2, 4, 8, 12 & 24 hours post dose on Days 5 (8 mg) and 14 (24 mg)
Secondary Time to Reach Maximum Plasma Concentration (Tmax) of Single Doses of 8 and 24 mg Tizanidine After Reaching Steady State. 0.5, 1, 1.5, 2, 4, 8, 12 & 24 hours post dose on Days 5 (8 mg) and 14 (24 mg)
Secondary Area Under the Plasma Concentration-time Curve During a Dosing Interval (AUCt) of Single Doses of 8 and 24 mg Tizanidine After Reaching Steady State. 0.5, 1, 1.5, 2, 4, 8, 12 & 24 hours post dose on Days 5 (8 mg) and 14 (24 mg)
