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 safety and efficacy of VEL-101 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 study is a randomized, multicenter, partially blinded, active control study to evaluate the safety and effectiveness of VEL-101 compared with tacrolimus in the prevention of rejection in patients undergoing kidney transplantation. Up to 120 de novo kidney transplant recipients will receive rATG with corticosteroids (CS), and mycophenolate as maintenance therapy, and will be randomized 1:1:1 to receive either VEL-101 (low dose or high dose) or tacrolimus.
