Summary

This study tested a new medicine called tegoprubart in 127 people who received a kidney transplant. The goal was to see if it works better than the standard drug tacrolimus at preventing the body from rejecting the new kidney. Participants took the study drug and were monitored for one year to check kidney function and side effects.
