Multicentric Prospective Clinical Study to Evaluate the Aktiia Optical Blood Pressure Monitoring (OBPM) Device Compared to Standard Home Blood Pressure Monitoring (HBPM) in Hypertensive Patients When Blood Pressure Lowering Medications Intake
Source: ClinicalTrials.gov · Last updated 5 Feb 2026
Brief summary (registry, in English)
Study design: Prospective, multicentric, randomized, comparative study Study duration: between 4 and 19 weeks depending on the study group. Population: minimum 35 hypertensives (stage 1 or stage 2) participants divided into 3 groups depending on hypertension criteria. GROUP 1 = untreated hypertensives, stage 1 or stage 2; GROUP 2 = hypertensives, stage 1, who are taking antihypertensive monotherapy; GROUP 3 = hypertensives, stage 1 or stage 2, who are taking antihypertensive treatment that doesn't allow them to have controlled blood pressure. Device Under Test (DUT): Aktiia device Reference: HBPM (Aktiia cuff) Periods of treatment: For GROUPS 1 and 2, 2 weeks of treatment for each antihypertensive medication followed by a washout period of 2 weeks (3 antihypertensive medications in total with a fixed dose; medication intake order is randomly assigned). For GROUP 3, an individualized new antihypertensive medication will be prescribed during the consultation with the investigator that will be administered for 3 weeks.
