After getting a new kidney through a transplant, people need to take special drugs called anti-rejection drugs. These help the body accept the new kidney. In this study, doctors want to see if a drug called abatacept, taken by injection at home, works as well as belatacept, which is given through an IV (a needle in the vein) in a clinic. Researchers are checking if abatacept can prevent kidney rejection and if it's safe and useful.

• The study lasts for 12 months, and you’ll switch from belatacept to abatacept 2-5 months after your transplant.
• Participants must be 18-70 years old and have had their first kidney transplant.
• After the study, you’ll follow a doctor-directed treatment plan.

To join, you need to be healthy in certain ways, like having a good kidney function, no history of serious infections like hepatitis or HIV, and not having had another organ transplant. If you meet the criteria and are willing to be part of this study, you can help find better ways to make kidney transplants work smoothly.
