Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate the long term safety and efficacy of AT-1501 (tegoprubart) compared with tacrolimus in patients undergoing kidney transplantation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, open-label, active control extension study to assess the long-term safety and efficacy of AT-1501 (tegoprubart) compared with tacrolimus in the preservation of allograft function after kidney transplantation.

The number of patients enrolled for OLE study will depend on the enrollment in the Parent studies. To be eligible for participation in this study, participants must have completed a designated Parent study.

Participants in this study will continue the treatment regimen they were receiving in the Parent study. Dose regimens will include either AT-1501 (tegoprubart) or tacrolimus.
