The purpose of this study is to see if treating patients who have high levels of donor specific alloantibodies post-transplant with bortezomib might prevent the development of transplant glomerulopathy and preserve allograft function.

Primary Outcome Measures:
  • The Incidence of a Combined Endpoint of Death-censored Graft Loss or Greater Than 50% Reduction in Estimated Glomerular Filtration (eGFR) in Study Subjects. [ Time Frame: 60 months after enrollment in the study ]

Enrollment: 4
Study Start Date: December 2011
Study Completion Date: March 2015
Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Bortezomib
Bortezomib is a type of targeted chemotherapy
Drug: Bortezomib
Patients randomized to bortezomib treatment will receive 2, 4-dose cycles of drug followed by a 2 month "hiatus". At the end of this time, subjects will be re-evaluated for the appropriateness of receiving a 3rd and 4th cycle of bortezomib. Bortezomib will be given subcutaneously (under the skin). If unable to give subcutaneously, bortezomib will be given as a single IV (injection into vein) over a time of 3 to 5 seconds. Patients will receive up to 4, four-dose cycles of 1.3 mg/m(2) (based on body surface area).

Inclusion Criteria:

  • Female subject is either postmenopausal for at least 1 year before the screening visit, surgically sterilized, or if they are of childbearing potential agree to practice 2 effective methods of contraception from the time of signing the informed consent form through 30 days after the last dose of bortezomib, or agree to completely abstain from heterosexual intercourse.
  • Male subjects, even if surgically sterilized (i.e. status postvasectomy), must agree to 1 of the following: practice effective barrier contraception during the entire study treatment period and through a minimum of 30 days after the last dose of study drug or completely abstain from heterosexual intercourse.
  • Kidney transplant recipients (living and deceased donors) who received a transplant in the last 3 years and have high Donor Specific Antibody (DSA) levels (defined as Mean Fluorescent Intensity levels >2000 by solid phase and single antigen bead LABscreen assays).

Exclusion Criteria:

  • Patients who are recipients of ABO (blood type) incompatible kidney transplants.
  • Patient with an Glomerular Filtration Rate (eGFR) ≤30 m/min at time of study entry.
  • Patient with biopsy proven transplant glomerulopathy (Banff 2007 - cg score ≥2) within 2 months prior to randomization.
  • Patients with biopsy-proven acute rejection at the time of randomization defined as Acute Cellular Rejection Patients with documented biopsy proven recurrence of disease or de novo glomerular disease post-transplant prior to enrollment.
  • Patient has a platelet count of <30 x 10(9)/L within 14 days before enrollment.
  • Patient has an absolute neutrophil count of <1.0 x 10(9)/L within 14 days before enrollment.

  • Patients who are HIV-positive or HBsAg-positive.
  • Recipients of a kidney from a donor who tests positive for HIV, HBsAg or anti-HCV.
  • Patients with current or recent severe systemic (pathogen detected in blood or Cerebrospinal fluid) infections within the 4 weeks prior to randomization.
  • Diagnosed or treated for another malignancy within 3 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy, or low-risk prostate cancer after curative therapy.
  • Patient is currently receiving everolimus, sirolimus, or azathioprine as one of the immunosuppressive agents and intends to remain on this regimen.
  • Participation in clinical trials with other investigational agents not included in this trial, within 14 days of the start of this trial and throughout the duration of this trial.
  • Inability to perform followup or to undergo protocol biopsy.
  • Active diabetic neuropathy at the time of treatment initiation.
  • Patient has ≥Grade 2 peripheral neuropathy.
