To make belatacept available for recipients of a renal allograft who are currently intolerant to or have contraindications to CNIs and/or m-TOR inhibitors and are either:

• unable to construct an adequate immunosuppression regimen due to nonrenal toxicity / contraindication (and withdrawing the causative agent would lead to renal graft loss) OR
• at imminent risk of losing the allograft kidney due to nephrotoxicity and have no other options for renal replacement therapy

OR

• At imminent risk of losing allograft kidney due to nephrotoxicity
