Summary:

      Kidney transplantation is the best treatment for many patients with kidney failure. Sometimes
      a transplanted kidney is rejected by the patient's immune system. Many types of immune system
      cells, including B cells, are active in rejection. B cells produce antibodies against
      anything the body sees as non-self, like germs or a transplanted kidney. Most medicines that
      help prevent transplant rejection affect cells other than B cells. Belimumab is a medication
      used to treat a disease called lupus. Belimumab slows development of antibody-producing B
      cells. This study will test whether belimumab works on parts of the immune system that cause
      rejection. Twenty to thirty adults getting a kidney transplant will be in this study. Like
      flipping a coin, a computer will randomly assign half to be given belimumab and half to be
      given placebo (a fake medicine). Patients and doctors will not know which medicine was
      assigned until the study is over. A total of 7 doses of study medicine will be given through
      a vein. One dose will be given during transplant surgery, and the other 6 will be given 2, 4,
      8, 12, 16 and 20 weeks after transplant surgery. Usual transplant medicines will also be
      given. After all of the doses have been given, patients will be watched and tested at 24, 36,
      and 52 weeks after the transplant surgery. Blood samples will be tested to see what study
      medicines do to the immune system in transplant patients. If patients get a kidney biopsy,
      the samples will be tested to see if belimumab had any effect. Patients will be asked many
      questions to see if they are having any side effects. The study will be done at Addenbrooke's
      Hospital in Cambridge and Guys &St Thomas Hospital in London, United Kingdom. A
      pharmaceutical company, GlaxoSmithKline, is funding the study.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Eligible for kidney transplantation: Considered eligible for transplantation after
             undergoing multidisciplinary evaluation at the institution at which the
             transplantation will be performed

          -  Donor characteristics: Receiving a deceased donor kidney or a living donor kidney
             allograft

          -  Age & Gender: Male or female between 18 and 75 years of age, inclusive, at the time of
             signing the informed consent

          -  Female Subjects: Not pregnant or nursing and at least one of the following conditions
             apply: a. Non-childbearing potential defined as pre-menopausal females with a
             documented tubal ligation or hysterectomy or postmenopausal defined as 12 months of
             spontaneous amenorrhea. In the absence of confirmatory laboratory assessments [(a
             blood sample with simultaneous follicle stimulating hormone (FSH) > 40 million
             international units per milliliter (MIU/mL) and estradiol < 40 picogram per milliliter
             (pg/mL) (<147 picomole per liter [pmol/L])] in questionable cases, female subjects
             will be required to use one of the contraception methods as described by the
             investigator or designee, until confirmatory results become available; b. Questionable
             post-menopausal status and agrees to use one of the contraception methods as described
             by the investigator or designee, from Day 0 until 16 weeks after the last dose of
             investigational product or until postmenopausal status is confirmed with a blood
             sample with simultaneous follicle stimulating hormone (FSH) > 40 MIU/mL and estradiol
             status who are using hormone replacement therapy (HRT) will be required to use one of
             the contraception methods as described by the investigator or designee, until
             post-menopausal status is confirmed. For most forms of HRT, at least 2-4 weeks will
             elapse between the cessation of therapy and the blood draw; this interval depends on
             the type and dosage of HRT. Following confirmation of their post-menopausal status,
             they can resume use of HRT during the study without use of a contraceptive method; c.
             Child-bearing potential and agrees to use one of the contraception methods as
             described by the investigator or designee, from Day 0 until 16 weeks after the last
             dose of investigational product.
