Safety and Efficacy Study Comparing Thrombin for Arterial Sealing

Completed · Phase 3

Conditions studied: Hemostasis of Arterial Punctures

In brief

This trial is designed as a prospective, multi-center, randomized, double blinded clinical trial to evaluate the safety and efficacy of the Thrombin VSI. An immunological sub-study to assess antibody and coagulation changes in the subjects following exposure to the Vascular Solutions Diagnostic Duett Pro manufactured with Thrombin VSI and Thrombin JMI will be conducted as a component of this trial with a subset of the enrolled study subjects. Two hundred seventy (270) subjects will be enrolled in this trial. A minimum of 50% of the subjects will be interventional subjects and up to 50% will be diagnostic subjects. All 270 subjects will provide blood specimens at baseline and at the 30 day follow-up visit for evaluation in the immunologic sub-study. Within the 270 subjects enrolled, a minimum of 45 subjects treated with the Thrombin VSI and a minimum of 45 subjects treated with the Thrombin JMI will provide blood specimens at the 60 day follow-up visit to be evaluated in the immunologic sub-study. The primary efficacy objective is to demonstrate that the device time-to-hemostasis for the study group treated with the sealing device manufactured with Thrombin VSI is non-inferior to the study group treated with the sealing device manufactured with Thrombin JMI. The primary safety objective is to demonstrate a device-related major complication rate for the study group treated with the sealing device manufactured with Thrombin VSI that is non-inferior to the device-related major complication rate observed for the study group treated with the sealing device manufactured with Thrombin JMI.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• The subject is 18 years of age or older
• The subject is undergoing a diagnostic or interventional endovascular procedure via a retrograde femoral arterial access
• The subject is willing and able to provide appropriate informed consent
• The subject is willing and able to comply with the requirements of the study protocol, including the predefined follow-up evaluations

You may not qualify if…

• Exclusion criteria determined prior to procedure:
• The subject has a history of clinically severe peripheral vascular disease documented as any of the following:
• Severe claudication (walking < 100 feet)
• Absent pulses in the affected limb
• ABI < 0.5 at rest
• Known diameter stenosis ≥ 50% in the iliac or femoral artery on the affected side
• Prior vascular bypass surgery involving the affected femoral artery
• Prior stent placement in the vicinity of the arterial puncture site
• The subject is known to be, or suspected to be, pregnant (verified in a manner consistent with institution's standard of care), or is lactating
• The subject has a pre-existing severe non-cardiac systemic disease or pre-existing terminal illness
• The subject has had an acute myocardial infarction ≤ 72 hours before the catheterization procedure
• The subject is unable to ambulate at baseline
• The subject is known to require an extended hospitalization (e.g., subject is undergoing CABG surgery)
• The subject has a known bleeding disorder (including thrombocytopenia [< 100,000 platelet count], thrombobasthenia, hemophilia, or von Willebrand disease)
• The subject is receiving Coumadin/warfarin therapy and has an INR > 2.0 on the day of, or the day before the study procedure. (INR of > 2.0 should not result in a dose change prior to the study procedure. If dosage changed, test should be repeated prior to the procedure)
• The subject has a known allergy to bovine derived products or any other materials used in the Diagnostic Duett Pro Sealing Device
• The subject has undergone prior use of a closure device in the ipsilateral common femoral artery ≤ 6 months before the current catheterization procedure
• The subject has undergone prior use of manual compression for closure in the ipsilateral common femoral artery ≤ 6 weeks before the current catheterization procedure
• The subject has undergone current, recent, or prior use of an intra-aortic balloon pump through the existing arterial puncture site
• The subject is unavailable for follow-up
• The subject is currently participating in another investigational device or drug trial
• The subject has previously participated in this trial (Protocol 0106)
• Exclusion criteria to be determined during the procedure:
• The subject has an antegrade puncture
• The subject's arterial introducer sheath is <5F or > 9F or longer than 15.2 cm in overall length
