The purpose of this study is to offer Panel Reactive Antibodies [PRA] reduction treatment to high responder renal transplant patients who otherwise may never be compatible with a potential organ donor. PRA reduction is offered in the following phases:

  1. Immunological Testing
  2. Transplant Nephrectomy
  3. Pharmacologic Therapy
  4. Plasmapheresis
  5. Transplant

Condition Intervention Phase
End Stage Renal Disease
Phase 4

Primary Outcome Measures:
  • The Percent of Sensitized Patients Treated With PRA Reduction Pharmacological Therapy, Including Cytogam, Who Become Cross-match Compatible With Potential Living Donor [ Time Frame: four weeks ] [ Designated as safety issue: No ]
    The percent of sensitized patients treated with PRA Reduction Pharmacological Therapy, including Cytogam, who become cross-match compatible with potential living donor. Treatment success defined as achieving a decrease in donor specific antibody and eliminating cross-match incompatibility sufficient to allow transplantation.

Secondary Outcome Measures:
  • Monitor Graft Survival [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Monitor Patient Survival [ Time Frame: 5 years ] [ Designated as safety issue: No ]

Enrollment: 26
Study Start Date: January 2002
Study Completion Date: April 2012
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: CMVIG followed by PP
MMF or rapamycin was given with CMVIG for 4 weeks followed by plasmapheresis
400mg/kg IV (60mg/kg/IV/hr initially, titrated up) once a week up to four weeks
Other Names:
  • Cytomegalovirus Immune Globulin - Intravenous
  • Cytogam

Detailed Description:

Patients with high level of preformed antibodies (panel reactive antibodies [PRA]) to donor antigens make identification of a suitable donor difficult. For most transplant centers, 20-35% of patients waiting for a kidney transplant comprise this challenging group. These patients have a wait time of over five years and have many incompatible cross-matches with potential organ donors.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Renal transplant recipients with a potential living donor who is incompatible (T-&/or B-cell locus) due to recipient high PRA or MHC antibodies
  • PRA greater than or equal to 20% within last twelve months
  • Recipient and donor accepted as potential candidates by the LifeLink Healthcare Renal Transplant Committee

Exclusion Criteria:

  • Patients with known allergy to CytoGam(R), Cellcept, Rapamycin
  • Patients who will receive IVIG or CytoGam(R) for any cause prior to protocol process
  • ABO incompatibility
  • Patients not capable of following through the treatment for various reasons as determined by treating physicians
  • Any potential recipient who is pregnant or becomes pregnant
  • Exclusion for Plasmapheresis: known allergy to ethylene oxide or natural rubber latex.
  • Exclusion for Plasmapheresis: Intake of ACE-inhibitor or Angtiotensiin-receptor blockers in the last 24 hours prior to plasma exchange
