    • BPAR > 2R
    • antibody mediated rejection (AMR),
    • Any treated rejection,
    • Rejection associated with hemodynamic compromise (HDC).

Safety and Efficacy of Desensitization Therapy in Sensitized Participants Awaiting Heart Transplantation
A Prospective, Randomized, Multicenter, Two-parallel Arm Study Evaluating the Overall Efficacy and Safety of Desensitization Therapy on Selected Patients Awaiting Heart Transplantation

The purpose of this research study is to find out if the drug Bortezomib (VELCADE ®), along with a procedure called plasmapheresis, can be effective at desensitization.

Bortezomib works is by decreasing plasma cells in the blood. Plasma cells produce antibodies. Plasmapheresis is a procedure that removes antibodies from the blood. Plasma cells and the antibodies they produce can be involved in rejection after organ transplantation. This trial is trying to see if decreasing plasma cells and antibodies with Bortezomib and plasmapheresis can reduce complications while participants are waiting for their transplant and improve heart transplantation outcomes.

Phase 2
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
  • Transplantation
  • Organ Transplantation
  • Heart Transplantation
  • Drug: Bortezomib
    Other Name: VELCADE®
  • Procedure: Plasmapheresis on days 0, 1 and 2.
  • No Intervention: No Desentization Therapy Pre-transplantation.
  • Experimental: Desensitization Therapy
    plasmapheresis for 3 consecutive days (treatment days 0, 1 and 2) followed by concomitant bortezomib dosed at 1.3 mg/m2 as a 3 to 5 second bolus intravenous inejection on treatment days 0, 3, 7 and 10. The first dose of bortezomib is administered between 4-8 hours after the first plasmapheresis session is completed and there must be at least 96 hours between the second and third dose of bortezomib.
    Interventions:
    • Drug: Bortezomib
    • Procedure: Plasmapheresis on days 0, 1 and 2.

Inclusion Criteria:

  • Subject must be able to understand and provide informed consent;
  • Candidate for a primary heart transplant recipient (single organ transplant);
  • cPRA of greater than 30% with a threshold using MFI of 3,000 or SFI of 60,000
  • Status 1 (1A or 1B) enrollment and randomization to occur within 2 weeks after status 1 listing;
  • Female subject is either postmenopausal for at least 1 year before the screening visit, is 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.
  • Negative test for HIV, HBsAg, HBcAb, and HCV Ab within 6 months prior to study entry.

Exclusion Criteria:

  • Recipient of multiple solid organ or tissue transplants;

  • Radiation therapy within 3 weeks before randomization. Enrollment of subjects who require concurrent radiotherapy (which must be localized in its field size) should be deferred until the radiotherapy is completed and 3 weeks have elapsed since the last date of therapy;
  • Patients with a platelet count of less than 75,000 within 7 days prior to enrollment;
  • Patients with an absolute neutrophil count of less than 1,500 within 7 days prior to enrollment;
  • Patients with >1.5 x ULN Total Bilirubin;
  • Patients with any grade or history of neuropathy;
  • Any condition that, in the opinion of the investigator, would interfere with the subject's ability to comply with study requirements;
