Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

PATIENTS MUST:

  • Have coronary artery disease and be scheduled to undergo a coronary artery bypass (CABG) procedure that is to include at least two segments of autogenous vein (sequential grafts do not count as two separate grafts).
  • Be between 18 and 80 years old.
  • Have a documented negative serum pregnancy test for all women of childbearing potential.
  • Be using an acceptable method of birth control if of reproductive potential.
  • Have agreed to participate voluntarily and signed and dated an IRB-approved, Patient Informed Consent form.
  • (If one of the first 2400 patients enrolled) have agreed to participate voluntarily and signed and dated an IRB-approved, Patient Informed Consent form for the Angiography population.
  • Note: Patients who are to receive an arterial bypass to the left anterior descending artery in addition to the two vein grafts required by the protocol ARE eligible for this study.
  • Note: Patients ARE eligible for enrollment regardless of whether the planned procedure is to be on or off cardiopulmonary bypass pump.
  • Note: Patients who do not wish to undergo elective Angiography at one year SHOULD NOT be enrolled in the first 2400 patients.

About this study

Official title: A Phase III, Multi-Center Randomized, Double-Blind, Placebo-Controlled Trial of the Ex Vivo Treatment With CGT003 of Coronary Vein Grafts in Patients Undergoing Coronary Artery Bypass Graft Procedures

The purpose of this study is to determine the efficacy of graft pretreatment with CGT003 (E2F Duplex Decoy), as compared to placebo, on the incidence of patients experiencing vein graft failure after coronary artery bypass surgery.

Read the detailed description

Coronary vascular disease manifested by narrowing of the coronary arteries is one of the more common manifestations of atherosclerotic vascular disease. The clinical manifestations of coronary artery disease include death, angina pectoris, myocardial infarction, congestive heart failure and arrhythmia. Restoration of circulation to the heart may be undertaken using a variety of techniques including angioplasty, stenting, and bypass grafting.

Approximately 359,000 patients underwent coronary bypass procedures in the U.S. in 1999. Long term studies have observed an incidence of vein graft occlusion at 19% at 1 year, 25% at 5 years and 50% by 15 years after operation for an overall rate of 2.5% per year after the first year of observation. The consequences of graft failure are as significant as those of primary atherosclerotic disease and include ischemia, myocardial infarction and death.

CGT003 is a novel therapeutic that is under investigation as a treatment to prevent vein graft failure. It acts by inhibiting the transcription factor, E2F, which is activated in response to injury such as that which occurs when thin-walled vein grafts are exposed to the pressures of the arterial circulation. Blockade of E2F inhibits smooth muscle cell proliferation and redirects the vein graft remodeling that occurs within the first several days after implantation towards medial hypertrophy and strengthening of the medial layer and blunts formation of neointima. Inhibition of neotinimal formation coupled with expansion of the media should result in a decreased risk of the accelerated atherosclerosis and consequent vein graft failure over several years.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing CGT003 (E2F Duplex Decoy) in people with Coronary Artery Disease, run by Anesiva, Inc. at 154 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 May 2006. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 154 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00042081, which also lists 5 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 5 May 2006; AzTrials last refreshed its copy on 8 Nov 2026.
