Study summary

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.

Inclusion criteria

  • Is at least the local legal age of consent for clinical studies and at least aged 18 years and less than 70 years
  • Agree to use measures consistent with local regulations
  • 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

Exclusion Criteria:

  • Any history of prothrombotic disorder or history of thrombosis or hypercoagulable state, excluding vascular access clotting
  • 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
  • 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 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
  • History of current alcohol, drug, or medication abuse as assessed by the investigator
  • Pregnant or lactating state or intention to become pregnant during the study

The full list of criteria can be found in the protocol.

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
