Brief Summary:
A Single-Dose, Phase 1b, Multicenter, Open-Label Study to Assess the Pharmacokinetics, Safety and Tolerability, and Pharmacodynamics of Tizanidine at 4 Different Oral Dose Levels in Pediatric Subjects 2 to 16 Years Old With Mild to Moderate Spasticity Due to Cerebral Palsy.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Spasticity Due to Cerebral Palsy | Drug: Zanaflex Capsules | Phase 1 |
Evaluation of the study's progress after the amendment remained challenging with continued pre-screen failures noted in areas of Botox injection inclusion; family participation refusal / disinterest and gastric or jejunostomy tube placement. A third protocol amendment to improve enrollment was discussed with the Investigators who did not believe further amendment would overcome the barriers expressed by parents that would subject their children to an intense study time commitment without direct benefit. The investigative sites were notified that the study was closed to enrollment March 27, 2012.

Primary Outcome Measures :
- Pharmacokinetic (PK) Parameter AUC0-8 (Area Under the Concentration-time Curve From Time 0 to 8 Hours) of a Single Dose of Tizanidine at 4 Different Dose Levels in Children and Adolescents With Cerebral Palsy and Mild to Moderate Spasticity. [ Time Frame: Baseline and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, and 8 hours ]
Baseline: immediately before the standardized meal (i.e., before administration of tizanidine) on dosing day
0.25, 0.5, 1, 1.5, 2, 3, 4, 6, and 8 hours after administration of tizanidine
PK parameters will be derived by using WinNonlin Pro (version 5.0.1 or later, Pharsight Corp).
Secondary Outcome Measures :
- Pharmacokinetic (PK) Parameter Cmax (Maximum Observed Drug Concentration in Plasma) of a Single Dose of Tizanidine at 4 Different Dose Levels in Children and Adolescents With Cerebral Palsy and Mild to Moderate Spasticity. [ Time Frame: Baseline and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, and 8 hours ]
Baseline: immediately before the standardized meal (i.e., before administration of tizanidine) on dosing day
0.25, 0.5, 1, 1.5, 2, 3, 4, 6, and 8 hours after administration of tizanidine
PK parameters will be derived by using WinNonlin Pro (version 5.0.1 or later, Pharsight Corp).
