Carfilzomib i Belatacept do odczulania (ADAPT)
Pomiar wpływu karfilzomibu i belataceptu na allogeniczne odczulanie u potencjalnych biorców przeszczepu nerki (ITN089ST)
Some kidney transplant candidates have a very low chance of getting a kidney transplant because their immune systems are "highly sensitized" to most kidney donors. Being "highly sensitized" means that they will likely have to wait a long time (more than 5 years) before an acceptable donor is found for them or, they never receive a compatible donor, and die while on the kidney transplant waitlist.
The purpose of this study is to find out whether two drugs, carfilzomib (Kyprolis®),and belatacept (Nulojix®), can make these kidney transplant candidates less sensitized, and make it easier and quicker to find a kidney donor for them.

Szczegółowy opis
This study enrolled 21 eligible participants, 18 to 65 years of age, with end stage renal failure on dialysis who are on the waiting list for a deceased donor transplant with calculated panel reactive antibodies (cPRA) ≥99.9% or >98% (with >5 years of waiting time) or, those with cPRA >98% and an human leukocyte antigen (HLA)-incompatible approved living donor who have not received a transplant after 1 year in a paired kidney exchange program. The study will evaluate whether the study treatment is safe and can lower the participant's immune system's sensitization to kidney donors, making it easier to find a well-matched kidney for them.
Participants in the study were enrolled in two consecutive Cohorts. The total duration of participation in the study will be 76 weeks for Cohort 1 and 68 weeks for Cohort 2. Participants who undergo kidney transplantation while enrolled in the study will have 52 weeks of follow up post-transplant.
The duration of participation for living donors is one study visit. Their participation in the study ends upon completion of this study visit.

Eksperymentalny: Cohort 1
The two investigational agents used in this study are carfilzomib and belatacept. Per protocol, Carfilzomib administered intravenously:
Per protocol, Belatacept: -Belatacept will be administered intravenously on days 29 (week 4), 33 (week 5), and weeks 6, 8, 12, 16, then at a lower dose at week 20, 24, 28, 32, 36, 40, 44, 48, 52, and 56. Dosing is based on the recommended dose in the package insert. |
Administered: Intravenously (IV). Carfilzomib is administered intravenously, on two consecutive days, each week for three weeks per cycle. In this study, subjects will receive 2 cycles of carfilzomib. Dosing for each cycle is based on the recommended dosing for carfilzomib monotherapy in the package insert. Carfilzomib is a proteasome inhibitor indicated for the treatment of patients with multiple myeloma. In this study, carfilzomib will be used in highly sensitized subjects without myeloma who are awaiting a kidney transplant.
