About this study

Official title: Gemini Angioplasty and Arterial Measurement Evaluation (GAAME) An Evaluation of the Metricath Gemini System, a Percutaneous Interventional Device Intended to Make Arterial Lumen Measurements and Perform Percutaneous Transluminal Angioplasty Dilations.

The purpose of the Metricath Gemini System is to pre-dilate the target treatment area, take arterial lumen measurements in a native section of artery or within the deployed stent and perform further dilation of the deployed stent if required. In this manner, the Metricath Gemini System can assist the Interventionalist by providing arterial measurements prior to stenting, performing pre-stenting angioplasty, taking within stent measurements to help determine if the stent is fully deployed, and by performing post-stenting dilations to further dilate the stent if required.

Read the detailed description

Several recent clinical studies have suggested that proper vascular stent deployment directly affects clinical outcome, and the rate of re-stenosis. These studies suggest that angiography alone is not sufficient to ensure proper vascular stent deployment, and that re-stenosis rates will decline if proper stent apposition has occurred. The importance of proper stent sizing and apposition is further emphasised with the increasing use of drug eluting stents, the drug effects of which are only realized upon contact with the arterial wall.

Angiometrx Inc. developed the Metricath Arterial Measurement System in response to the need for increased stent sizing and deployment. The Metricath System measures the diameter and cross sectional area of arteries using an intravascular balloon catheter attached to a computerized console. Considering the ease and rapidity of obtaining Metricath results, this technique may form an alternative to evaluate vessel area and stent expansion.

The Metricath System was 510(k) cleared in the U.S. in June, 2003, and received European and Canadian market approvals in 2004.

Angiometrx Inc. has now developed the next generation of Metricath System, which incorporates a second balloon on the catheter, intended for angioplasty purposes. The Metricath Gemini System is comprised of a dual balloon catheter which is attached to the same Metricath computerized console as the Metricath System. As with the Metricath System, the Metricath Console operates the inflation and deflation of the Gemini measurement balloon and provides arterial cross-sectional area and diameter. The Metricath Gemini angioplasty balloon is controlled separately in the traditional manner using a hand-held inflation device, attached to a port in the hub of the catheter.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To observe the safety of the device, as determined by freedom from MACE (major adverse cardiac events) within 30 days post-procedure. (time frame: 30 days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00399646, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2009.
