NCT ID: NCT01302691

Last Updated: 2019-03-15

Results Overview

Sitting diastolic blood pressure was measured by automated sphygmomanometer pre-dose on Day 1 (baseline) and at 24 ± 2 hours after the last study drug administration at Week 8. The difference between the baseline and Week 8 assessments was calculated and summarized by treatment arm.

Participant Flow

All participants received single-blind losartan 50 mg (L50) + amlodipine 5 mg (A5) and placebo for L50/(H12.5)/A5 during 8-week Filter/Screening Period. A total of 707 entered the Filter/Screening Period and 327 were randomly assigned to 1 of the 2 treatment arms for the Double-blind Treatment Period.

PRIMARY outcome

Timeframe: up to 14 days after last dose of study drug (up to 10 weeks)

Population: All randomized participants who received at least 1 dose of study drug.

An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. The percentage of participants who experienced at least 1 AE during the 10-week treatment and follow-up period were summarized by study drug received.

An SAE is any AE occurring at any dose or during any use of Sponsor's product that does the following: results in death; is life threatening; results in persistent or significant disability/incapacity; results in or prolongs an existing inpatient hospitalization; is a congenital anomaly/birth defect; is a cancer; is associated with an overdose; is another important medical event.
