SCRATCH-HTN trial is a randomised sham-controlled study designed to evaluate the safety, acceptability, and efficacy of trans-cutaneous autonomic neurostimulation (tAN) in a cohort of uncontrolled medicated hypertensive patients.~SCRATCH-HTN trial is designed to test the hypothesis that tAN treatment is safe and acceptable to the patient, improves the control of blood pressure in hypertension and sense of well-being amongst those who are receiving the active treatment as compared to those on sham treatment.~The study will recruit 63 patients with systemic arterial hypertension (male and female aged ≥18 years) who are receiving between one and three oral antihypertensive medications and remain hypertensive with blood pressure (BP) above target levels detailed below in the eligibility criteria. The participants will be randomly allocated to the active (tAN) or sham (sham-tAN) arms of the trial on 2:1 basis, respectively.~The total treatment duration is 12 weeks. Self-administration of 30 min of tAN or sham stimulations once per day for the first two weeks, and then once every week for the rest of the trial period.
This is a pilot, sham-controlled, double blind, single-site device clinical trial designed to evaluate the safety, acceptability and efficacy of non-invasive autonomic neuromodulation in a cohort of 63 adult patients with uncontrolled high blood pressure.
