Prevention of Vascular Access Graft Failure in Patients With Chronic Renal Failure Requiring Hemodialysis

• Status: Terminated
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine the effect of recipient vein pretreatment of edifoligide (E2F Decoy), compared to placebo, on graft/recipient vein stenosis in polytetrafluoroethylene (PTFE) vascular access grafts placed for hemodialysis at 6 months after enrollment.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Anesiva, Inc.

Criteria

Inclusion Criteria:

• Be scheduled to undergo placement of a new straight or loop arm PTFE arteriovenous hemodialysis access graft or a Vectragraft® (Thoratec, Inc.)

• Be currently receiving chronic dialysis or be expected to begin hemodialysis within 4 weeks of placement of the index PTFE graft

• Have undergone an assessment of patency (such as venography) of central veins if any of the following conditions have occurred on the ipsilateral arm intended for graft placement: presence of collateral veins, upper extremity edema or increased size (relative to the contralateral arm), history of subclavian catheter, transvenous pacemaker, or history of trauma or surgery that may have involved the neck or chest veins

• Be > 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 and agree to continue using the birth control for at least 3 months following the graft procedure

• Have agreed to participate voluntarily and have signed and dated an IRB/EC approved, Patient Informed Consent form

Exclusion Criteria:

• Have an intended recipient vein >6 mm or <3 mm in diameter

• Have a history of three or more previous PTFE grafts

• Have uncorrected central vein (including the subclavian vein) stenosis

• Have markedly diminished arterial pulses in the access location (unless adequate flow has been documented by arteriography or Doppler ultrasound)

• Anticipate receipt of a renal transplant within 6 months of enrollment into this study

• Have anticipated use of the index PTFE graft <14 days after enrollment (this does not apply to Vectragraft®)

• Have a known allergy to iodinated contrast

• Have a known hypercoagulable state (e.g., antithrombin III deficiency; antiphospholipid or anticardiolipin antibodies; Factor V Leiden; circulating lupus anticoagulant; current, active, heparin-induced thrombocytopenia; Protein C or S deficiency; or a history of recurrent deep venous thrombosis not related to AV access)

• Have been in another investigational (i.e., nonapproved) drug or device study within the previous 30 days or prior participation in another clinical study with E2F Decoy

• Have been previously enrolled in this study for an earlier access graft

• Have any comorbid, nonrenal condition that makes 6-month survival questionable (e.g., end-stage cancer, advanced heart failure)

• Have a known or suspected history of drug or alcohol abuse within the previous 6 months

• Have a known allergy to any component of the investigational product (drug or device), including latex
