Dose Ranging, Safety and Tolerability of TOPROL-XL® Extended-Release Tablets in Hypertensive Pediatric Subjects — 307A  

Hypertension Clinical Trial

Official title:
Dose Ranging, Safety and Tolerability of TOPROL-XL® (Metoprolol Succinate) Extended-Release Tablets (Metoprolol CR/XL) in Hypertensive Pediatric Subjects: A Multicenter, Double-Blind, Placebo-Controlled, Randomized, Parallel-Group Study

Clinical Trial Summary

This was a 4-week, multicenter, double-blind, placebo-controlled, randomized, parallel-group study to determine the antihypertensive dose range, efficacy, safety and tolerability of TOPROL-XL ® (metoprolol succinate) extended-release tablets (metoprolol CR/XL) in hypertensive pediatric subjects. The study population included school age children (age 6 to < Tanner Stage 3) and adolescents (> Tanner Stage 3 to age 16) of both genders. No more than 50% of the randomized subjects could be adolescents (> Tanner Stage 3 to 16 years old). Since response to some therapies in adult hypertension appears to be different in black and non-black populations, recruitment was aimed at a mixture of black and non-black children. The design included a 1-week screening period (for treatment naive subjects), a 1-week single-blind placebo run-in period, and a 4-week double-blind treatment period. Eligible subjects were randomized to the double-blind period with a once daily oral dose of metoprolol CR/XL to one of three target doses: 0.2, 1.0 and 2.0 mg/kg, or placebo. Dosing was weight adjusted. The dose range for this study was 12.5 to 200 mg daily. Subjects were closely monitored and evaluated at the end of Weeks 1, 2, 3 and 4 during the double-blind treatment period.
