  • ♦ Percentage of patients without graft failure or need for intervention at 24 weeks.
  • Primary Safety/Tolerability Endpoints: the percentage of patients delaying or discontinuing therapy for an adverse event and the incidence of treatment-emergent adverse events (AEs) and serious

  • Participants With Arthrosclerotic Cardiovascular Complications [ Time Frame: up to week 25 ] [ Designated as safety issue: Yes ]
    Counts of participants who had treatment-emergent arthrosclerotic cardiovascular complications, specifically myocardial infarction, arterial thromboses, or cerebrovascular events.
  • Kaplan Meier Estimates for Time to Graft Failure or Intervention [ Time Frame: up to 12 months ] [ Designated as safety issue: No ]
    The time to graft failure or intervention was defined as the time from first dose of study drug to the first time graft failure or intervention. Participants who did not have graft failure or intervention at the end of the study were censored at the last known time that the participant had angiography.
  • Percentage of Participants With Patency of Index and Non-Index Lesions at 24 Weeks [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    The patency (unblocking) for index lesions is defined as <50% of stenosis and no PFTE graft thrombosis at 24 weeks. The patency for non-index lesions is defined as <50% of stenosis and no new non-index lesions at 24 weeks.
  • Secondary Efficacy Endpoints:
  • ♦ Incidence of atherosclerotic cardiovascular complications (e.g. myocardial
  • infarction, arterial thromboses, or cerebrovascular events);
  • ♦ Time to graft failure or intervention;
  • ♦ Patency of the index lesion at 24 weeks;

Use of ABI-007 for the Prevention of Vascular Access Graft Failure in Patients Undergoing Hemodialysis
A Pilot Phase II Trial Of ABI-007 (A Cremophor El-Free, Protein Stabilized, Nanoparticle Paclitaxel) For The Prevention Of Vascular Access Graft Failure In Patients Undergoing Hemodialysis

This study is designed to confirm the safety of the proposed dose and schedule of ABI-007 for hemodialysis patients with vascular access device failure, and to obtain preliminary data on the effectiveness of such treatment.

This is an open-label, pilot, phase II study to assess the feasibility of administering ABI-007 intravenously [IV] over 3-5 minutes to patients with hemodialysis graft dysfunction (i.e., either a thrombosed polytetrafluoroethylene (PTFE) graft, or a patent but dysfunctional PTFE graft). Patients with graft dysfunction who are successfully treated with angioplasty will start treatment after angioplasty or during their first dialysis through the graft following intervention, and will receive 3 subsequent treatments of ABI-007 at 35 mg/m^2 on weeks 5, 13 and 21.
