A Pivotal Study To Evaluate The Effectiveness of Isometric Handgrip Therapy In Prehypertensive And Hypertensive Patients

Stopped early · Not applicable · Has a placebo group

Conditions studied: Hypertension, Systolic

In brief

This is a double-blind, sham-controlled clinical trial assessing the effectiveness of personalized isometric handgrip device therapy. Approximately 230 patients who present with a Systolic Blood Pressure reading of ≤ 149mmHg and who have not taken any antihypertensive medication for more than 30 days will be enrolled.

Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or female of any ethnicity between 18 and 80 years of age
• Diagnosed with prehypertension or hypertension and verified during the Baseline visit
• Non-use of antihypertensive medication for ≥30 prior to screening
• Currently not taking any antihypertensive medications or decline to take any antihypertensive medications(e.g., diuretic, angiotensin-converting enzyme inhibitor (ACEI), angiotensin II receptor blocker (ARB), ] beta-blocker (BB), renin inhibitor (RI), calcium channel blocker (CCB) or alpha-adrenergic agonist (clonidine))
• Sufficient vision with the patient able to see the screen prompts on the device, sufficient hearing with the patient able to hear the device audio prompts, sufficient hand strength (demonstrated by a maximum voluntary contraction equaling 35 units of force in both hands measured by the device)
• Baseline Blood Pressure measurements collected and study device training completed during the Baseline visit
• Non-use of medications and over the counter (OTC)supplement regimen related to hypertension throughout the study duration
• Only one patient per household can participate in the study, eliminating the potential of unblinding
• Able to comply with study procedures and agrees to complete all required study visits and associated activities
• Ability to give written informed consent in either English, Spanish or French •≤149 mmHg, Systolic Blood Pressure wherein patients who present with Systolic Blood Pressure readings ≥140 mmHg will receive heightened monitoring throughout the first month of the study

You may not qualify if…

• Pregnant or not using adequate contraception
• Blood Pressure ≥150 mmHg (systolic) and/or >90 mmHg (diastolic)
• History of heart failure
• Hospitalization due to a hypertensive emergency, with impending or progressive target organ dysfunction (i.e., renal dysfunction, left ventricular hypertrophy or CNS involvement) within the past six (6) months
• >10 mmHg difference in Systolic Blood Pressure between the right and left arms collected during screening
• Unstable Blood Pressure, defined as >5 mmHg variance between any two (2) consecutive weekly readings (with a maximum of four (4) attempts) to determine a baseline BP measurement
• Arm circumference greater than 45cm
• Acute illness, infection, or inflammation
• Unstable cardiovascular disorder, such as MI, unstable angina, significant arrhythmia, stroke, or TIA within the last six (6)months, or other serious comorbidity impacting life expectancy to < than a 1 year
• Rest or exertional angina pectoris in the previous six (6) months
• History of solid organ transplant
• Secondary form of hypertension (HTN) etiology, including but not limited to primary aldosteronism, chronic steroid therapy and Cushing syndrome, pheochromocytoma, aorta coarctation or untreated thyroid or parathyroid disease
• Concurrent participation in an investigational clinical study that has not completed the follow-up period or planned participation in another study within the next six(6) months
• Any condition or personal circumstance that, in the judgment of the investigator, might interfere with the collection of complete, good quality data or the completion of the research study
• Currently own or have owned another Zona Plus device and are,or have been,voluntarily performing the isometric handgrip activities.
