ARGX-117 hos afdøde donor nyretransplanterede modtagere i risiko for forsinket graftfunktion (VARVARA)
En fase 2, multicenter, randomiseret, dobbeltblindet, placebokontrolleret undersøgelse for at vurdere sikkerheden, effektiviteten og tolerabiliteten af ARGX-117 til forbedring af allograftfunktionen hos modtagere af en afdød donor nyreallograft med risiko for forsinket graftfunktion
The main purpose of this study is to evaluate the safety, efficacy and tolerability of ARGX-117 in Deceased Donor Kidney Transplant Recipients at Risk for Delayed Graft Function.
The study consists of 2 parts: part A comprises the main study period, and part B comprises the long-term observational follow-up period. During part A, after the screening period, eligible participants will be randomized to receive either ARGX-117 or placebo, entering the treatment and evaluation period (duration of up to 52 weeks). After the treatment period, participants will enter a follow-up period of up to 12 weeks.
The total study duration varies from approximately 64 weeks up to 5 years post-transplant depending on whether a participant enrols in part B of the study.
