Summary

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.

Detailed description

This study with N = 35 participants minimum, over 2 to 6 visits, depending on the study group, has been designed to compare Aktiia device systolic and diastolic blood pressure measurements against HBPM reference measurements in participants taking 3 successive BP-lowering medications during 2 weeks per treatment for GROUPS 1 and 2, while GROUP 3 will receive, during 3 weeks, an individualized medication decided by the investigator. For GROUPS 1 and 2, periods of treatment are followed by 2 weeks of washout. Study participants are: For GROUP 1, hypertensive Stage 1 (SBP 140-159 mmHg or DBP 90-99 mmHg) or hypertensive Stage 2 (SBP 160-179 mmHg or DBP 100-109 mmHg) that are naive of antihypertensive treatments at the inclusion in the study. For GROUP 2, hypertensives Stage 1 (SBP 140-159 mmHg or DBP 90-99 mmHg) with no other cardiovascular risk factors who are taking an antihypertensive monotherapy, for whom previous treatment will be stopped at the study inclusion and will be resumed for the last 4 weeks of the study participation. For GROUP 3, uncontrolled hypertensive Stage 1 (SBP 140-159 mmHg or DBP 90-99 mmHg) or hypertensive Stage 2 (SBP 160-179 mmHg or DBP 100-109 mmHg) who are taking antihypertensive treatment that doesn't allow them to have controlled blood pressure. Study participants are asked to: Wear the Aktiia bracelet continuously every day for 4 to 19 weeks in total, depending on the study group, Initialize their bracelet with the Aktiia cuff at different time points, Measure their blood pressure with an HBPM (Aktiia cuff) twice per day, Take their BP-lowering medications during the treatment periods, Complete 2 to 3 different surveys, depending on the study group, to give their feedback on Aktiia product use compared to HBPM.

Interventions

Type	Name	Description
OTHER	Aktiia Optical Blood Pressure Monitoring (OBPM) device and antihypertensive drugs (monotherapy and bitherapy)	The device under test is Aktiia Optical Blood Pressure Monitoring (OBPM) device and the comparator is the Aktiia cuff. For study GROUP 1: Study drugs are: * Perindopril MEPHA (Angiotensin Converting Enzyme (ACE) inhibitors). * Indapamide MEPHA (Diuretics). * Amlodipine MEPHA (Calcium channel blockers). In each study treatment period, subjects in GROUP 1 will receive one of the following for each treatment period: monotherapy with Indapamide, bitherapy with Indapamide plus Perindopril, or bitherapy with Perindopril plus Amlodipine.
OTHER	Aktiia Optical Blood Pressure Monitoring (OBPM) device and antihypertensive drugs (monotherapy)	Study drugs: * Perindopril MEPHA (Angiotensin Converting Enzyme (ACE) inhibitors). * Indapamide MEPHA (Diuretics). * Amlodipine MEPHA (Calcium channel blockers). In each study treatment period, subjects in GROUP 2 will receive one of the following monotherapies: Perindopril , Indapamide, or Amlodipine.
OTHER	Aktiia Optical Blood Pressure Monitoring (OBPM) device and individualized antihypertensive treatment	For study GROUP 3: Subjects will be prescribed an individualized new antihypertensive treatment at their consultation with the Investigator at Visit 1.
