Trial Outcomes & Findings for Effect of Febuxostat on Blood Pressure (NCT NCT01496469)

NCT ID: NCT01496469

Last Updated: 2015-08-31

Results Overview

The change in 24-hour mean SBP measured at final visit or Week 6 relative to baseline. Ambulatory blood pressure monitoring measures blood pressure at regular intervals throughout the day and night. The 24-hour mean is the average of all measurements recorded for 24 hours after dosing.

PRIMARY outcome

Timeframe: Baseline and Week 6

Population: FAS included all participants who were randomized and received at least 1 dose of double-blind study medication and had a baseline value and at least 1 post-baseline value available, with last observation carried forward.

The change in 24-hour mean SBP measured at final visit or Week 6 relative to baseline. Ambulatory blood pressure monitoring measures blood pressure at regular intervals throughout the day and night. The 24-hour mean is the average of all measurements recorded for 24 hours after dosing.
