Trial Outcomes & Findings for Combination of Olmesartan and Hydrochlorothiazide in Essential Hypertension (NCT NCT00430950)

NCT ID: NCT00430950

Last Updated: 2019-01-10

Results Overview

Change in mean trough sitting diastolic Blood Pressure between OM/HCTZ 20/25 mg vs. 40/25 mg, in those patients inadequately controlled on OM 40 mg monotherapy, after eight weeks of double blind treatment, as compared to baseline. Change = Week 16 - Week 8 (baseline).

Participant Flow

92 principal investigators screened patients at clinical sites in Europe (8 in Belgium, 17 in Germany, 12 in the Netherlands, 17 in Poland, 19 in Russia, 10 in Slovakia, and 9 in the Ukraine).Sites were either hospitals or general practitioners. First patient in: 05 December 2006 Last patient out: 07 May 2008

Trial is 2 week taper-off phase and 2 treatment periods. Period I - 8-week open-label OM 40mg. Only non-responders eligible to randomise into Period II. Period II - 8-week double-blind patients assigned into one of two arms. Results provided for Period II only.

PRIMARY outcome

Timeframe: 8 weeks

Population: The main analysis will be performed on the full analysis set last observation carried forward (LOCF). Pooling will be applied for small centres.

Change in mean trough sitting diastolic Blood Pressure between OM/HCTZ 20/25 mg vs. 40/25 mg, in those patients inadequately controlled on OM 40 mg monotherapy, after eight weeks of double blind treatment, as compared to baseline. Change = Week 16 - Week 8 (baseline).

SECONDARY outcome

Timeframe: 8 weeks

Population: Exploratory analysis: ANCOVA was used to compare the differences in change from baseline (Visit 4, Week 8) to Week 16 (Visit 6) in daytime, nighttime and 24-hr ABPM dBP and sBP.

Change = Week 16 - Week 8 (baseline).
