Njurtransplantation är det enda botande behandlingsalternativet för patienter som befinner sig i kronisk njursviktsstadium 5. Dagens mest använda immunsuppressiva kombinationsbehandling i klinisk praxis består av calcineurinhämmaren takrolimus, mykofenolatmofetil och kortikosteroider i form av prednisolon. Belatacept (Nulojix®) är ett fusionsprotein som introducerades på marknaden 2011 och ska ses som ett alternativ för primär immunsuppressiv behandling. Verkningsmekanismen för belatacept är att hämma aktiveringen av T-celler genom blockera co-stimulatoriska signaler från antigenpresenterande celler. Teorin bakom belatacept är att man genom en mer specifik immunsuppression ska kunna undvika de nefrotoxiska biverkningar som calcineurinhämmarna takrolimus(Prograf®) och ciklosporin(Sandimmun®) ofta ger.
