Desensitization of Highly Sensitized Deceased Donor Renal Transplantation Candidates

May 1, 2017 updated by: Johns Hopkins University

Phase 2 Study of IVIg and Rituximab for Desensitization of Highly Sensitized Deceased Donor Renal Transplantation Candidates

Some patients who need kidney transplants have high levels of antibodies that make them incompatible with most potential deceased donor kidney offers. These patients are considered highly-sensitized and are very difficult to transplant because the likelihood that they will receive a compatible organ is very low. There are some medications and procedures that can decrease the antibody levels and this can increase the chance of finding a compatible donor for these patients. In this study the investigators will give two medications (IVIg and Rituximab) to highly-sensitized patients who are on the waiting list for a deceased donor kidney transplant. After the investigators administer these medications, the investigators will continue to check for compatibility as organ offers are received. If a compatible organ offer is received, the investigators will perform the transplant using that organ. The investigators hypothesize that these medications will lower antibody levels and increase the chance that a these patients are able to receive a compatible kidney transplant.

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: IvIg with Rituximab
Drug: IVIg and rituximab

A maximum of four doses (each single dose being 2gm/kg) of IVIg will be administered over a four-month period, with one dose administered each month. Each single dose of 2gm/kg will be administered in two half-doses (1gm/kg each) to be given one day apart, with one day of hemodialysis on the intervening day between the two half-doses.

If a compatible kidney transplant organ offer is received, upon admission to the hospital and immediately prior to the transplant operation, patients will receive a single infusion of Rituximab (375 mg/m2 BSA).

Other Names:
  • Gamunex and Rituxan
