Study of the Pathogenicity and Humoral Immune Response Induced by BK Virus in Lung Transplant Recipients

France120 participantsStarted 2020-01

Plain-language summary

BK virus (BKV) is a ubiquitous virus that infects more than 80% of the population. In case of immunosuppression, BKV can replicate and induce nephropathies in renal transplant recipients or haemorrhagic cystitis in bone marrow transplant recipients. The disruption of the balance between BKV replication and immune control is considered the key element in the development of these pathologies. During lung transplantation, patients undergo intense immunosuppression that favors the reactivation of persistent viruses such as EBV, CMV and probably BKV. Although the data on EBV and CMV reactivation are very clear and allow optimal management, the prevalence of BKV replication and its clinical impact in lung transplant recipients remains unknown at this time. The aim of this study is to know the incidence and clinical impact of BKV replication in lung transplant recipients. Moreover, the results will help to better understand the interaction between the virus and his host, with a focus on the humoral and cellular immune response against BKV. The results could possibly enable to define predictive markers of BKV replication and of its evolution.

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.
