Overview
The WEARABLE-BP study will evaluate the clinical value of obtaining continual measurements using the Aktiia G1 Optical Blood Pressure Monitoring (OBPM) device in hypertensive patients, compared to using a traditional upper arm cuff for home BP monitoring. The WEARABLE-BP study aims to compare the change in unattended automated office blood pressure from baseline to 6 months between two study groups: those given an Aktiia G1 BP monitor and those given a traditional upper arm BP cuff.
Detailed description
This is a prospective open-label two-arm randomized clinical trial (RCT). The investigational device of this study is the Aktiia G1 BP monitor.
There is an active 6- month comparison period between two BP monitoring devices, followed by a 6-month follow-up period when all patients will have an Aktiia G1 BP monitor.
Each participant will be randomly assigned to one of two study groups: Group 1, or Group 2. The randomization will be a simple, based on a single computer-generated sequence of random assignments.
* Group 1: Aktiia G1 BP monitor (or "Hilo") - intervention 82 participants. These participants will receive an Aktiia G1 BP monitor and wear it through the entire 12-month study period. * Group 2: Traditional BP monitor (upper arm cuff) - active control 82 participants. These participants will receive a traditional BP monitor (validated upper arm cuff) to use for the 6 months comparison period. At the 6-month visit, they will return the traditional BP monitor and receive an Aktiia G1 BP monitor for the 6-month follow-up period.
During the study, the patient completes online survey covering lifestyle, health, and socioeconomic environment.
Interventions
- Device Aktiia G1 BP monitor for 12 months
These participants will receive an Aktiia G1 BP monitor and wear it through the entire 12-month study period. - Device Traditional BP monitor for 6 months / Aktiia G1 BP monitor for 6 months
These participants will receive a traditional BP monitor (validated upper arm cuff) to use for the 6 months comparison period. At the 6-month visit, they will return the traditional BP monitor and receive an Aktiia G1 BP monitor for the 6-month follow-up period.
Primary outcome measures
- Change in automated unattended office BP between the two groups from baseline to 6 months [Time frame: 6 months]
Secondary outcome measures (3)
- Percentage of hypertensive subjects achieving BP control at 6 months in the intervention group compared to the standard treatment group [Time frame: 6 months]
- Difference in patient engagement and lifestyle features between the 2 groups [Time frame: 0, 6 and 12 months]
- Difference in mean average Aktiia G1 BP measurement after a 6-month period [Time frame: 6 months]
