The TARGET BP Clinical Program

Together, the Peregrine System Infusion Catheter and Ablative Solutions dehydrated alcohol make up the Peregrine Kit which is used during the Peregrine Procedure.

TARGET BP I Clinical Trial

Under a Clinical Trial Application (CTA), Ablative Solutions is studying the Peregrine Kit for hypertension with targeted delivery of alcohol, an investigational medicinal product. The global TARGET BP I trial is a multi-center, blinded, randomized, sham-controlled trial to evaluate the safety and efficacy of ASI’s drug-device combination therapy for the treatment of uncontrolled hypertension despite pharmacologic treatment, in conjunction with antihypertensive medical therapy. Enrollment in the company’s randomized global TARGET BP I multi-center trial began in the U.S. and European centers in 2019 and is currently enrolling.


Data from the TARGET BP I trial will be used to seek approval in Europe and the United States for the system's use for the treatment of hypertension, in conjunction with medical therapy.

TARGET BP OFF-MED Clinical Trial

The TARGET BP OFF-MED Clinical Trial is evaluating the Peregrine Kit. Early studies1-3 of the Peregrine Catheter using a neurolytic agent suggested the procedure can reduce blood pressure by deactivating specific nerves surrounding the renal (kidney) arteries that, through over-signaling, can contribute to high blood pressure.

The purpose of the trial is to investigate the effectiveness of the Peregrine Kit in treating high blood pressure. Participants will include patients who do not take antihypertensive medication and those on 1-2 antihypertensive medications who will stop taking these medications for 3 months during the trial, in order to clearly evaluate the benefit of the procedure alone in managing high blood pressure. Enrollment has completed for this trial, which is currently in the follow-up phase.
