Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

* Are diagnosed with ESRD and have been stable on chronic dialysis for at least 3 months
* Are recipients of de novo or second-time, single kidney transplant from a deceased donor, either DCD (donation after cardiac/circulatory death) or DBD ( (donation after brain death)
* Are ABO compatible with donor allograft, except for type A2 donor to type B recipient kidneys
* Have a negative cross match
* Have received pretransplant vaccinations for: Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae, or are willing to receive the vaccinations approximately 3 to 4 months posttransplant

Exclusion Criteria

* Any known history of complement deficiency
* Evidence of peritonitis in participants on peritoneal dialysis
* Received any solid organ, bone marrow, or hematopoietic stem cell transplant, with the exception of prior first kidney transplant
* High risk within the study period for recurrence of underlying renal disease in the opinion of the investigator
* Clinically significant comorbidity, recent major surgery (within 3 months of screening), history of any treatment nonadherence, or intention to have surgery during the study other than kidney transplantation; or any other medical condition that, in the investigator's opinion, would confound the results of the study or put the participant at undue risk
* Clinically significant active bacterial, viral, or fungal infection
* History of malignancy unless considered cured by adequate treatment, with no evidence of recurrence for 5 years or more before first study drug administration. Adequately treated participants with the following cancers can be included at any time: Basal cell or squamous cell skin cancer; Carcinoma in situ of the cervix; Carcinoma in situ of the breast; Incidental histological finding of prostate cancer
