Study Details

Study Description

Brief Summary

The TARGET BP I Trial is a randomized, blinded, multi-center, international, sham-procedure controlled trial, comparing renal denervation performed with the Peregrine System Kit in the treatment group to the sham control group (without renal denervation - no alcohol infusion). Subjects will be randomized in a 1:1 fashion to treatment versus sham control via central randomization.

Condition or Disease Intervention/Treatment Phase
  • Drug: Dehydrated alcohol
  • Device: Peregrine System Kit (Sham Procedure)
Phase 3

Detailed Description

The TARGET BP I Trial is a randomized, blinded, multi-center, international, sham-procedure controlled trial, comparing renal denervation performed with the Peregrine System Kit in the treatment group to the sham control group (without renal denervation - no alcohol infusion). Subjects will be randomized in a 1:1 fashion to treatment versus sham control via central randomization.

The TARGET BP I clinical trial uses a percutaneous catheter to deliver very small amounts of alcohol (neurolytic agent). The patient population for this trial is comparable to those used in other renal denervation studies, but also incorporates lessons learned from recent trials of renal denervation. This is to enable the study of an optimized patient population who stands to benefit from the intervention, in a manner that reduces possible study bias.

This trial is intended to evaluate the safety and efficacy of the Peregrine Catheter when used to deliver a 0.6 mL volume of alcohol to the perivascular area of the respective renal arteries while patients are adequately managed with oral antihypertensive medications.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Treated with Peregrine System Kit

The experimental group will receive an infusion of Dehydrated Alcohol Injection, USP into the perivascular space of the renal arteries with the Peregrine Catheter. A total of 0.6mL of the alcohol will be delivered to the perivascular space of each renal artery. The drug will only be delivered once to each renal artery during the treatment procedure.

Drug: Dehydrated alcohol
Dehydrated Alcohol Injection, USP is used in the study.
Other Names:
  • Ethanol
  • Sham Comparator: Renal Angiography Only (Sham Procedure)

    The sham control group will only have diagnostic renal angiography performed. There will be no insertion of the Peregrine Catheter and no alcohol infusion (i.e. no renal denervation).

    Device: Peregrine System Kit (Sham Procedure)
    Pre-procedural diagnostic renal angiography only, performed for confirmation of anatomical eligibility prior to randomization
