A Study of Losartan Compared to Losartan/HCTZ in Pediatric Patients With Hypertension (0954A-327)

Hypertension Clinical Trial

Official title: A Randomized, Double-Blind, Active Comparator Study to Evaluate the Antihypertensive Efficacy and Safety of Losartan/HCTZ Combination as Compared to Losartan Monotherapy in Pediatric Patients With Essential Hypertension

Status Terminated

Clinical Trial Summary

The purpose of this study is to test the safety and effectiveness of Losartan as compared to Losartan/HCTZ in pediatric patients (6 to 17 years) with high blood pressure.

Clinical Trial Description

Participants who meet eligibility requirements will enter the single-blind Filter Period. Participants with either sitting systolic blood pressure (SiSBP) or sitting diastolic blood pressure (SiDBP) >=95th percentile for gender/age/height will be administered either losartan 25 mg or losartan 50 mg depending on body weight (<50 kg and >=50 kg, respectively). After 3 weeks, if SiSBP or SiDBP is >=95th percentile, participants will titrate to either losartan 50 mg or 100 mg according to weight. Participants with both SiSBP and SiDBP <95th percentile will be excluded from the study. After an additional 3 weeks, participants whose blood pressure (either SiSBP or SiDBP) remains >=95th percentile will then enter the double-blind phase. Participants who meet all entry criteria will be randomized in a 1:1 fashion to either losartan or losartan/hydrochlorothiazide (HCTZ) for 4 weeks and will be stratified according to body weight (<50 kg and >=50 kg). Participants whose weight is <50 kg will be randomized to losartan 50 mg or losartan50 mg/HCTZ 12.5 mg. Participants weighing >=50 kg will be randomized to losartan 100 mg or losartan/HCTZ 100 mg/12.5 mg. At the end of double-blind treatment, participants may enter a 20-week double-blind extension and will continue on their randomized therapy with losartan or losartan/HCTZ.

40 participants were enrolled and screened; the trial was terminated before any participants were randomized into the double-blind treatment period. ;
