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.
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.
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.
