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
Kidney Transplantation
End Stage Renal Disease
Drug: Cytogam
Phase 4

Study Type: Interventional

Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment

Further study details as provided by Tampa General Hospital:

Primary Outcome Measures:
  • Determine number 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 ]

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
Estimated Study Completion Date: December 2014
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Cytogam
    400mg/kg IV (60mg/kg/IV/hr initially, titrated up) once a week up to four weeks
    Other Names:
    • Cytomegalovirus Immune Globulin - Intravenous
    • CMVIG
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
