Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patient is between 18 and 65 years of age, inclusive, with end-stage renal disease awaiting kidney transplantation.
• Patient with eligible living donor will have: DSA against living donor of > 5,000 MFI or a positive T or B cell flow cytometry crossmatch.
• Patient that is on the kidney transplant waiting list awaiting a deceased donor transplant and has an iAb of > 8,000 MFI or has a current or peak calculated panel reactive antibody (cPRA) >20%.
• Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
• Female subject is either post-menopausal for one year prior to screening or surgically sterilized. Women of childbearing potential (WOCBP) must not become pregnant and so must be sexually inactive by abstinence (starting 2 weeks prior to the 1st belimumab and/or bortezomib dose) or use contraceptive methods with a failure rate of < 1% (starting 1 month prior to the 1st belimumab and/or bortezomib dose) for the duration of the study through 16 weeks after the last belimumab and/or bortezomib dose. WOCBP must have a negative urine or serum pregnancy test at screening and < 7 days prior to the first belimumab and/or bortezomib dose.
• Male subjects, even if surgically sterilized (i.e., status post vasectomy) must agree to 1 of the following: practice effective barrier contraception during the entire study treatment period and through a minimum of 16 weeks after the last dose of belimumab and/or bortezomib, or completely abstain from heterosexual intercourse.
• Review of pre-transplant medical clearance by the patient's transplant nephrologist to assure the patient is medically acceptable for study entry.
• Cardiac evaluation by transplant nephrologist with clearance documented in writing to participate in the study.

You may not qualify if…

• Know hypersensitivity to bortezomib, boron or mannitol, rituximab, belimumab or any of its components.
• Have a history of an anaphylactic reaction to parenteral administration of contrast agents, human or murine proteins or monoclonal antibodies.
• Subjects judged by the investigator to be at significant risk of failing to comply with the requirements of the protocol or unable to cooperate or communicate with the investigator.
• Abnormal ECG with clinically significant ventricular arrhythmias or other conduction abnormality that in the opinion of the investigator warrants exclusion of the subject from the trial.
• Myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure (Appendix A), uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. Prior to study entry, any abnormality on ECG performed within 30 days of consent has to be documented by the investigator or the patient's transplant nephrologist as not medically relevant.
• Patient has Grade 2 peripheral neuropathy by CTCAE criteria within 14 days before enrollment.
• Patients with an absolute neutrophil count < 1,000/mm3 or platelet count < 75,000/mm3 within 30 days of consent.
• Patient has received intravenous cyclophosphamide within 180 days prior to belimumab, any biologic investigational agent within 365 days prior to belimumab, or any non-biologic investigational agent within 30 days (or 5 half-lives, whichever is greater) prior to belimumab.
• Receipt of a live vaccine within 30 days prior to initiation of study treatment.
• Received blood transfusions within 30 days prior to trial entry.
• Have any intercurrent significant medical (other than renal disease) or psychiatric illness that the investigator considers would make the candidate unsuitable for the study.
• Have a historically positive HIV test or test positive for HIV within one year of consent.
• Hepatitis status:
• a. Hepatitis B: Serologic evidence of current or past Hepatitis B (HB) infection based on the results of testing for HBsAg and anti-HBc as follows: i. Patients positive for HBsAg or HBcAb historically or on testing performed within one year of consent are excluded b. Hepatitis C: Positive test for Hepatitis C antibody with a detectable viral load on testing performed within one year of consent.
• History of malignancy within the past 5 years that is not considered to be cured, with the exception of localized basal cell carcinoma of the skin (excised ≥ 2 years prior to randomization).
• Evidence of severe liver disease with abnormal liver profile (aspartate aminotransferase (AST), alanine aminotransferase (ALT) or total bilirubin > 1.5 times upper limit of normal (ULN)) on testing performed within 30 days of consent.
• Infection history: a)Currently on any suppressive therapy for a chronic infection (such as tuberculosis, pneumocystis, cytomegalovirus, herpes simplex virus, herpes zoster and atypical mycobacteria). b) Hospitalization for treatment of infection within 60 days of Day 0. c) Use of parenteral (IV or IM) antibiotics (antibacterials, antivirals, anti-fungals, or anti parasitic agents) within 60 days of Day 0.
• Pregnant or nursing (lactating) women and women who might become pregnant during the study.
• Have evidence of serious suicide risk including any history of suicidal behavior in the last 6 months and/or any suicidal ideation in the last 2 months or who in the investigator's judgment, pose a significant suicide risk.
• Have a history of a primary immunodeficiency.
• Have a significant IgG deficiency (IgG level < 400 mg/dl) or have an IgA deficiency (IgA level < 10 mg/dL).
• Have current drug or alcohol abuse or dependence, or a history of drug or alcohol abuse or dependence within 364 days prior to Day 0.
• Have any other clinically significant abnormal laboratory value in the opinion of the investigator warrants exclusion of the subject from the trial.
