Observational Study for Patients Receiving a Kidney Transplant After Vonsetamig Treatment

This study is for adults aged 18 to 70 who previously participated in the R5459-RT-1944 study and received at least one dose of vonsetamig, and then had a kidney transplant. The main goal is to continue observing how vonsetamig affects the body and to track your health outcomes after your kidney transplant. No new medication will be given during this study. Researchers will be looking at any side effects (adverse events) you experience for up to 12 months after your kidney transplant. The study plans to include 20 participants, but its current recruitment status is unclear.
