Drug Information available for: Belatacept

Arm Intervention/treatment
Experimental: Belatacept+VIB4920
Participants will be admitted to the transplant center for the administration of VIB4920 and belatacept and will be discharged on Day 3/4 at the discretion of the investigator. Participants will return to the study center to receive study drugs (VIB4920 and /or belatacept) weekly for 2 visits, then every 2 weeks for 5 visits, and then monthly for 9 visits for safety monitoring.
Drug: Belatacept
Belatacept Dose 1 will be administered intravenously on post-op Day 1, repeated on post-op Day 3 or 4, and at the end of Weeks 2, 4, 8 and 12; then Dose 2 every four weeks from Week 16 to Week 48.

Drug: VIB4920
VIB4920 Dose 1 will be administered intravenously on post-op Days 1, and 14, and at the end of Weeks 4, 6, 8 and 10; then will continue every four weeks from Week 12 to Week 48.




Primary Outcome Measures :
  1. Number of Participants With Treated Biopsy-proven Acute Rejection (tBPAR) of Grade 1A or Higher, Graft Loss or Death at Week 24 [ Time Frame: Week 24 ]

Criteria

Inclusion Criteria:

  • Recipients of a first renal transplant from standard criteria deceased, living unrelated or HLA non-identical living related donor.
  • Recipients who are at low immunologic risk:

    1. No donor specific antibodies (DSA), and
    2. Negative cross-match testing.
  • Recipients with up to date vaccination as per local immunization schedules.
  • Male and female participants who agree to follow protocol defined contraceptive methods.

Exclusion Criteria:

  • Participants receiving an allograft from an ABO-incompatible donor.
  • Participants treated with systemic immunosuppressive drug therapy for more than a total of 2 weeks within 24 weeks prior to informed consent form signature.
  • Participants who have undergone lymphodepleting therapy.
  • Participants with medical history of confirmed venous thromboembolism, arterial thrombosis, coagulopathy or known platelet disorders.
  • Participants with risk factors for venous thromboembolism or arterial thrombosis, prothrombotic status.
  • Participants requiring treatment with antithrombotic drugs (clopidogrel, prasugrel, warfarin, others).
  • Participants requiring long-term systemic anticoagulation after transplantation, which would interfere with obtaining biopsies.
  • Participants with any contraindication to kidney biopsy.
  • Cytomegalovirus (CMV)-seronegative recipients of a CMV-seropositive donor kidney, or unknown CMV serostatus.
  • Epstein-Barr virus (EBV)-seronegative or with unknown EBV serostatus.
  • Receipt of live (attenuated) vaccine within the 4 weeks before screening.
  • Participants with high potential of graft loss due to recurrence of underlying kidney disease.
  • Prior solid organ transplant or potential to require a concurrent organ or cell transplant.
  • Previous treatment with belatacept and cluster of differentiation 40 (CD40) or anti-CD40L agents.
  • Use of B cell depleting therapy, non-depleting B cell directed therapy e.g., belimumab or abatacept within 1 year prior to enrolment.
  • At screening, have adequate central laboratory test results.
  • Participants with severe systemic infections, current or within the 2 weeks prior to transplant surgery.
  • Positive test for chronic hepatitis B infection at screening.
  • Positive test for hepatitis C virus antibody.
  • Positive test for human immunodeficiency viruses antibody.
  • History of or active tuberculosis (TB), or a positive QuantiFERON®-TB Gold test at screening, unless previously treated for latent tuberculosis.
  • History of cancer, except as follows:

    1. In situ carcinoma of the cervix treated with apparent success with curative therapy > 12 months prior to screening; or
    2. Cutaneous basal cell or squamous cell carcinoma treated with apparent success with curative therapy.
  • Lactating or pregnant females.
