Description
Inclusion Criteria
Each patient must meet all of the following inclusion criteria to be enrolled in the study:
- 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performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
- Patient is between the 18 and 65 years of age, inclusive.
Patient is considered high risk for acute rejection based on any one of the following:
- Patient has a current Cytotoxic PRA≥ 20% or a peak Cytotoxic PRA ≥50%
- Patient has a T or B-cell positive crossmatch (by flow cytometry) with confirmed donor-specific antibodies on solid-phase assay.
- Historical positive serologic or cytotoxic crossmatch or DSA to donor
- Prior allograft loss with a history of more than one acute rejection episode.
- Female subject is either postmenopausal for at least 1 year prior to initiation of study treatment, is surgically sterilized, or if of childbearing potential, agrees 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 agrees to completely abstain from heterosexual intercourse. Women of childbearing potential must have a negative serum pregnancy test within the last 48 hours prior to receiving study medication.
- 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 30 days after the last dose of study drug, or completely abstain from heterosexual intercourse.
- Patient must have no known contraindications to treatment with bortezomib, rituximab, or thymoglobulin.
Exclusion Criteria
- Patients that have previously received or are receiving an organ transplant other than kidney.
- Patient who lost a previous allograft due to recurrence of disease
- Patient is receiving a HLA identical living related kidney transplant
- History of severe allergic or anaphylactic reactions to humanized or murine monoclonal or polyclonal antibodies
- Patients with an absolute neutrophil count of < 1,000/mm3 or platelet count < 100,000/mm3within 30 days of consent.
- Patient has Grade 2 peripheral neuropathy by CTCAE criteria within 14 days before enrollment.
- Myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure (see section 9.3), 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.
- Patients who are anti-HIV-positive, or HBsAg-positive or Anti-HCV positive on testing performed within one year of consent.
- Diagnosed or treated for 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.
- Patients with current or recent severe systemic infections within the 2 weeks prior to initiation of study treatment.
- Receipt of a live vaccine within 4 weeks prior to initiation of study treatment.
- Use of other investigational drugs within 30 days or 5 half-lives prior to initiation of study treatment, whichever is longer
- Evidence of severe liver disease by medical history or physical exam 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.
- Pregnant or nursing (lactating) women and women who might become pregnant during the study. Female subject is pregnant or breast-feeding. Confirmation that the subject is not pregnant must be established by a negative serum -human chorionic gonadotropin pregnancy test result within the last 48 hours prior to receiving study medication. Pregnancy testing is not required for post-menopausal or surgically sterilized women.
- EBV serologic mismatch (i.e. EBV+ donor transplanted to EBV- recipient)
- CMV serologic mismatch (i.e. CMV+ donor transplanted to CMV- recipient)

Incidence of Acute Rejection (Banff '97) or Antibody Mediated Rejection
Time Frame: 6 months
|
Antibody mediated rejection demonstrated to be due to, atleast in part, to anti-donor antibody at 6 months by Banff 97' criteria. Acute rejection IA - cases with significant interstitial infiltration (>25% of parenchyma affected) and foci of moderate tubulitis (>4 mononuclear cells/tubular cross section or group of 10 tubular cells). IB - cases with significant interstitial infiltration (>25% of parenchyma affected) and foci of severe tubulitis (>10 mononuclear cells/tubular cross section or group of 10 tubular cells) IIA - cases with mild to moderate intimal arteritis (v1) IIB - cases with server intimal arteritis comprising >25% of the luminal area (v2) III - case with transmural arteritis and/or arterial fibrinoid change and necrosis of medical smooth muscle cells (v3 with accompanying lymphoctic inflammation) |
