Rituximab and Intravenous Immunoglobulin (IVIG) for Desensitization in Renal Transplantation

Completed · Phase 1/Phase 2

Conditions studied: Kidney Transplant

In brief

The purpose of this study is to examine the safety and efficacy of IVIG in combination with Rituximab to lower the level of HLA-sensitive antibodies and block their ability to attack a transplanted organ in patients who are highly HLA-sensitized and are awaiting transplantation.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients eligible for the study will be those who have anti-HLA antibody (Panel Reactive Antibody [PRA]) of >30% and are eligible for transplantation at Cedars-Sinai Medical Center. We currently anticipate entering 20 patients over the course of the study. We currently have \~100 patients on our wait list that would meet the above criteria. Patients will be selected based on the ability of IVIG to inhibit the cytotoxic anti-HLA antibody activity in vitro. They will then receive IVIG 2gm/kg X1 on day 1 while on hemodialysis. Seven days later, the patients will receive Rituxan® 1gm in the CSMC Cancer Infusion Center as per protocol for Rituxan® infusion. The second Rituxan® infusion will be on day#22. The patients will have monitoring of anti-HLA antibody and outlined tests as shown above.
• Able and willing to give written informed consent and comply with the requirements of the study protocol
• Adequate liver function, as indicated by normal liver function tests (NL: AST, ALT, Bilirubin and negative tests for hepatitis C and hepatitis B.
• Negative serum pregnancy test (for women of child bearing age)
• Men and women of reproductive potential must agree to use an acceptable method of birth control during treatment and for twelve months (1 year) after completion of treatment.

You may not qualify if…

• Treatment with any investigational agent within 4 weeks of screening or 5 half-lives of the investigational drug (whichever is longer)
• Receipt of a live vaccine within 4 weeks prior to randomization
• Previous Treatment with Rituximab (MabThera® / Rituxan®)
• Prior antibody therapy
• History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies
• History of HIV (positive HIV, HIV conducted during screening)
• History of Hepatitis B and/or Hepatitis C
• History of recurrent significant infection or history of recurrent bacterial infections
• Known active bacterial, viral fungal mycobacterial, or other infection (including tuberculosis or atypical mycobacterial disease, but excluding fungal infections of nail beds) or any major episode of infection requiring hospitalization or treatment with i.v. antibiotics within 4 weeks of screening or oral antibiotics within 2 weeks prior to screening
• Lack of peripheral venous access
• History of drug, alcohol, or chemical abuse within 6 months prior to screening
• Pregnancy (a negative serum pregnancy test should be performed for all women of childbearing potential within 7 days of treatment) or lactation
• Concomitant malignancies or previous malignancies within the last five years, with the exception of adequately treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix.
• History of psychiatric disorder
• Significant cardiac or pulmonary disease (including obstructive pulmonary disease)
• Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that may affect the interpretation of the results or render the patient at high risk from treatment complications
• Inability to comply with study and follow-up procedures
• Laboratory Exclusion Criteria (at Screening)
• Hemoglobin: < 8.5 gm/dL
• Platelets: < 100,000/mm
• AST or ALT >2.5 x Upper Limit of Normal unless related to primary disease.
• Positive Hepatitis B or C serology
• Positive HIV
