Aortic Dissection Clinical Trial

Official title: Post-market Registry of the AMDS for the Treatment of Acute DeBakey Type I Dissection: PROTECT Registry

Status Recruiting

Clinical Trial Summary

The objective of this registry is to collect information on the performance and clinical benefits of the AMDS (Ascyrus Medical Dissection Stent) to treat patients with acute "DeBakey type I dissections" and with or without so called "preoperative clinically relevant malperfusion" and/or "intramural hematomas".

In a healthy aorta (the vessel that supplies blood to most of the body) the blood flows freely through the main lumen (a space inside the vessel where blood flows). The participants involved in this study have a tear that has separated the inner layer of the aorta wall and created a secondary channel (false lumen) in addition to the main channel (true lumen), and huts, the blood flows through both channels.

AMDS is a stent (a metal tube helping to keep the vessel open) that is placed in the descending thoracic aorta. AMDS is a medical device commercially available in the countries in which the study is being conducted and it is used as standard of care according to its indication.

Clinical Trial Description

Observational, prospective and retrospective, non-randomized, non-interventional study to investigate the performance and clinical benefits of the AMDS to treat patients with acute DeBakey type I dissections with or without clinically relevant preoperative malperfusion and/or intramural hematomas (IMH).

Participating physicians will be asked to provide their observations collected during routine care for patients they had decided to treat with AMDS. Informed consent of the patients to allow the use of their clinical records for the purpose of this observational study will be obtained before data are being collected.

A total number of 300 subjects will be enrolled in up to 30 sites in Europe and Canada. The AMDS will be implanted according to the instructions for use and at the discretion of the treating physician.

This registry was initiated by Ascyrus Medical GmbH in August 2019 (DARTS PM Registry). About 70 patients were enrolled at that time by German and Canadian sites under previous protocol. The patient's enrollment was put on-hold and the study has been re-started as PROTECT Registry with updated study documents as per JOTEC's standard operating procedures upon Ethics Committees approvals.

Patients already included in DARTS PM Registry will be re-consented (where applicable as per local regulatory requirements) to allow the retrospective and prospective collection of additional data points not included in the initial version of the protocol. It is also planned to retrospectively include up to 150 subjects of the 300 targeted subjects, which have been treated with AMDS and who consent to the collection of their data (if required by national law) and are willing to continue in this registry, if applicable. ;
