Description
Summary
The purpose of this study is to evaluate the efficacy, safety and tolerability of dual costimulation blockade with VIB4920 in combination of belatacept in adult male or female recipients of a renal allograft from a deceased, living unrelated or human leukocyte antigen (HLA) non-identical living related donor.

You can join if…
Open to people ages 18-70
- 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:
- No donor specific antibodies (DSA), and
- 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.
You CAN'T join if...
- Participants receiving an allograft from an ABO-incompatible donor.

- 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:
