Vasovist Magnetic Resonance Angiography (MRA) in Peripheral Arterial Occlusive Disease

August 5, 2011 updated by: Heidelberg University

Determination of Diagnostic Accuracy and Added Value of Vasovist®-Enhanced Peripheral MRA in Comparison to Intra-arterial Digital Subtraction Angiography (i.a. DSA) in Patients With Peripheral Artery Disease

This study aims at investigating the diagnostic accuracy of magnetic resonance angiography using the contrast agent Vasovist® in the detection of relevant vascular narrowing of the lower extremity. Patients who have been scheduled for intra-arterial conventional angiography are eligible for this trial.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients will only be included into the study if either MRA with extracellular contrast agents, computed tomography angiography, ultrasound or i.a. DSA have been performed beforehand and if the patient has been scheduled for an i.a. DSA to be performed. Vasovist® enhanced MRA imaging will be performed using a state-of-the-art 1.5T MR system. Recruitment, baseline examinations, Vasovist®-enhanced MRA of the vessel segments of interest and follow-up examinations will be performed in up to 8 radiological clinics in Europe. The safety follow-up period will be at least 12 hours but not more than 24 hours post injection of Vasovist® and includes the assessment of physical examinations and vital signs as well as the assessment of AEs. DSA must be carried out at least 12 hours after Vasovist® administration and only after the last follow-up visit has been performed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Description

Inclusion Criteria:

  • Patients who are willing to comply with the study procedures (e.g. being followed-up for 12 hours after the Vasovist injection).
  • Patients who have given their fully informed and written consent voluntarily.

Exclusion Criteria:

  • Being less than 18 years of age.
  • Women who are pregnant, lactating or who are of childbearing potential and have not had a negative urine pregnancy test the same day as administration of Vasovist. The manufacturer's instructions for performing the urinary pregnancy test are to be followed.

  • Having an underlying disease or concomitant medication which may interfere with efficacy or safety evaluations as planned in this study.
  • Having any physical or mental status that interferes with the informed consent procedure including self-signed consent.
  • GFR < 30 ml/m²/1.73m² (MDRD), values ≤ 1 week or patients on hemodialysis
  • Renal or liver transplant patients, including patients with scheduled liver transplant are excluded due to the potential risk for nephrogenic systemic fibrosis (NSF).
  • MR contraindications (pacemaker, magnetic clips, severe claustrophobia)
  • Known allergy to Gadofosveset
  • Presenting with history of anaphylactoid or anaphylactic reaction to any allergen including drugs and contrast agents.

  • Having received any investigational drug within 7 days prior to entering this study or who are planned to receive any investigational drug during the safety follow-up period.
  • Not being able to remain lying down for at least 30-45 min (e.g. patients with unstable angina, dyspnea at rest, severe pain at rest, severe back pain).
  • Being clinically unstable and whose clinical course during the 12 hours observation period is unpredictable.
  • Being scheduled for, or likely to require, any surgical intervention within 12 hours before or within the follow-up period.
  • Patients in whom i.a. DSA is contra-indicated preventing him/her from undergoing standard of reference (SOR) procedure.
  • Close affiliation with the investigational site; e.g. a close relative of the investigator.
