Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - cyclosporine or tacrolimus
Treatment: Drugs - sirolimus

Active comparator: 1 - Group 1: Continuation of CNI regimen

Experimental: 2 - Group 2: (CNI-Free) Conversion to SRL-based regimen


Treatment: Drugs: cyclosporine or tacrolimus
Cyclosporine and tacrolimus are provided by the sites and dosed to achieve a target trough level determined by the investigator; therefore, form, dosage, and frequency are site and patient specific. Duration should be 52 weeks on-therapy.

Treatment: Drugs: sirolimus
Oral (1 and 2 mg) tablets, dosing should be once daily to achieve a target trough level of 7- 15 ng/mL. Duration should be 52 weeks on-therapy.
