THRIVE- THerapeutic IntravasculaR Ultrasound (TIVUS™) REnal Denervation System Versus Sham for the Adjunctive Treatment of Hypertension

Официальное название

A Pivotal, Prospective, Multicenter, 2:1 Randomized, Double Blind, Controlled, Study Comparing the THerapeutic IntravasculaR Ultrasound (TIVUS™) REnal Denervation System Versus Sham for the Adjunctive Treatment of Hypertension (The THRIVE Study)

Обзор

The primary objective of the THRIVE Pivotal study is to demonstrate the adjunctive effectiveness and the safety of the TIVUS system in: 1. subjects with uncontrolled hypertension (HTN) receiving 0 - 2 anti-hypertensive drugs of different classes in whom the anti-hypertensive medications will be stopped for a 4-week wash-out period before RDN/Sham procedure and during 2 months after procedure. 2. subjects with controlled hypertension receiving 1 - 2 anti-hypertensive drugs of different classes and who accept to be off-medications for a 4-week wash-out period before RDN/Sham procedure and 2 months after the procedure

Подробное описание

THRIVE is an international, multicenter, randomized, double blind, sham-controlled study, designed to demonstrate the adjunctive effectiveness and safety of the TIVUS System in hypertensive subjects while subjects are maintained off-antihypertensive medications for a 4-week wash-out period before RDN/Sham procedure and 2 months after procedure. At two months after procedure, subjects with uncontrolled hypertension are put back on antihypertensive medication according to a medication escalation protocol. Unblinding will be performed at 6 months. Uncontrolled sham subjects can cross-over to RDN procedure at 6-months. The sham procedure will be minimally invasive to reduce risk to subjects. All subjects treated with TIVUS will be followed for a maximum of 36 months post procedure.

Вмешательства

  Renal artery catheterization procedure used to denervate the renal sympathetic nerves in the perivascular space using ultrasound energy.

Критерии участия

Критерии включения

• Appropriately signed and dated informed consent
• Male and female adults with age between ≥22 and ≤75 years at time of consent
• Documented history of hypertension
• Previously or currently prescribed antihypertensive therapy
• Subject has an office BP (average of 3 seated measurements) of:

• Uncontrolled BP: ≥ 140/90 mmHg <180/110 mmHg at Screening Visit (V0) while stable for at least 4 weeks on 0-2 anti-hypertensive medications of different classes\* and willing to stop anti-hypertensive medication(s) for 4 weeks wash-out and 2-months post-procedure, (subjects with a history of treatment with anti-hypertensive medications but are not currently taking any at screening will undergo a 4-week run-in period) or,
• Controlled BP: < 140/90 mmHg while stable for at least 4 weeks on 1-2 antihypertensive medications of different classes and willing to stop anti-hypertensive medication(s) for 4 weeks wash-out and 2-months post-procedure
• Able and willing to comply with all study procedures
• Subject is willing to have and is a good candidate for conscious sedation

Subjects who meet the following criteria will be considered eligible for randomization:

• Documented daytime systolic ABP ≥ 135 mmHg and < 180 mmHg after 4-week washout/run-in period.\*\*
• Suitable renal anatomy compatible with the renal denervation procedure, documented by renal CTA or MRA of good quality performed within one year prior to consent (a CTA or MRA will be obtained in subjects without a recent (≤1 year) cross-sectional renal imaging). The renal angiogram procedure done in the cath lab prior to randomization will serve as the final anatomy compatibility check.

• Potassium-sparing diuretics such as Amiloride hydrochloride and Triamterene may be prescribed in combination with another diuretic (e.g. a thiazide or loop diuretic) for their potassium conservation properties. In this situation, the diuretic combination is considered as a single class of anti-hypertensive.
