Trial Outcomes & Findings for An Examination of the Blood Pressure Lowering Ability and Safety of Olmesartan Medoxomil in Elderly Patients With Hypertension (NCT NCT00412932)

NCT ID: NCT00412932

Last Updated: 2009-09-22

Results Overview

All participants started the treatment arm with 20 mg olmesartan medoxomil (Olm). If their blood pressure was not controlled, participants were titrated at 3-week intervals to: Olm 40 mg, then, if needed Olm 40 mg + hydrochlorothiazide (HCTZ) 12.5 mg, then, if needed Olm 40 mg + HCTZ 25 mg This outcome measure included all participants at the end of the 12-week treatment period regardless of whether or not they were titrated. They had to have both baseline and 12-week ambulatory blood pressure measurements.

Participant Flow

Participants were recruited at 37 US sites (private medical practices and small clinics) over 13 months (Nov 29,06 to Dec 28,07) from each physician's clientele base. Approximately 200 eligible participants, men and women at least 65 years of age with hypertension or uncontrolled hypertension on current medication, were to receive active treatment

After 3-4 weeks of placebo, patients with a systolic pressure (SBP) ≥150 ≤199mmHg and diastolic pressure (DBP) ≤109 mmHg at the last 2 visits, and 8-hr daytime SBP \>140 and ≤199 mmHg and DBP ≤109 mmHg by ambulatory blood pressure monitoring were entered.All started with Olmesartan 20 mg and were titrated if their blood pressure was not controlled

Active Treatment Period
All participants started this arm with 20 mg olmesartan medoxomil (Olm). After 3 weeks participants were titrated to 40g Olm, if their blood pressure was not controlled. After 6 weeks they were titrated to the next step which now included Olm 40 mg + hydrochlorothiazide (HCTZ) 12.5 mg if their blood pressure was not controlled. After 9 weeks they were titrated to the next step which now included Olm 40 mg + HCTZ 25 mg if their blood pressure was not controlled.

PRIMARY outcome

Timeframe: baseline to 12 weeks

Population: 178 participants started the active treatment period. 23 dropped out. 150=The ambulatory blood pressure monitoring (ABPM) subset was defined as subjects who received at least one dose of active study medication and had a baseline and week 12 ABPM.

All participants started the treatment arm with 20 mg olmesartan medoxomil (Olm). If their blood pressure was not controlled, participants were titrated at 3-week intervals to: Olm 40 mg, then, if needed Olm 40 mg + hydrochlorothiazide (HCTZ) 12.5 mg, then, if needed Olm 40 mg + HCTZ 25 mg This outcome measure included all participants at the end of the 12-week treatment period regardless of whether or not they were titrated.
