ARGX-117 in Deceased Donor Kidney Transplant Recipients at Risk for Delayed Graft Function

United States, Australia, Austria103 participantsStarted 2024-02-17

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
