Study summary

This is a comparative, prospective, non-interventional study to evaluate immune response in patients with chronic kidney disease. The primary objective is to define immunodeficiency (phenotype and function of T cells) in patients with end-stage kidney disease. The second objective is to provide an in-vitro proof-of-concept of T-cell engineering in the context of end-stage kidney disease.

The study population was patients with chronic kidney disease.

Read the detailed description

The development of chronic kidney disease (CKD) and its progression to this terminal stage (end-stage kidney disease, ESKD) remains a significant source of reduced quality of life and premature mortality. ESKD represents the complete and definitive alteration of renal function requiring the use of renal replacement therapy (dialysis or kidney transplantation).

ESKD is associated with a significant increase in mortality, with a death rate of 10.9% and a median age of 77 years. Thus, the average survival of patients with ESKD is lower than that of the general population. Among the causes of death in ESKD, infectious diseases represent the 2nd cause of mortality and are responsible for 15 to 20% of deaths. The occurrence of complications increases with the decline of renal function, although individual risk remains poorly characterized. Thus, after infection, ESKD patients are at increased risk of complications, hospitalization, and death. This susceptibility to infections is explained by a complex alteration of the immune system, including a pro-inflammatory state and immunodeficiency. However, this immunodeficiency is still partially understood. Premature-aged T cells were found, with a decrease in naive T cells and an increase in memory T cells, suggesting a more advanced T-cell differentiation than in the population of the same age.

The study aims to describe immunodeficiency in patients with ESKD in order to better assess the infection risk for each patient, particularly in patients awaiting kidney transplantation.

This is a comparative, prospective, non-interventional study. Three groups of participants will be included: 1) patients with ESRK, 2) patients with stage 3 CKD, and 3) healthy donors. Participants will be included after being informed and after obtaining no opposition to participate. Immunodeficiency in patients with chronic kidney disease will be performed from a single blood sample.

A total of 100 participants will be included in this study based on the detection probability of naïve T cells (45% in patients with stage 3 CKD and healthy donors vs 10-15% in ESKD patients) and considered a power of 80% and an alpha risk of 5%.

The development of blood tests to evaluate the antiviral immune response could allow for the definition of new milestones for the development of future treatments or diagnostics for these diseases.

Inclusion criteria

  1. Male or female ≥ 18 years
  2. Informed participants who did not object to participating in the study

Exclusion criteria

Exclusion Criteria:

  1. Chronic progressive infections

Terms in these criteria, in plain language(1)

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. The primary outcome is to characterize T cell immunodeficiency in our cohort of end-stage kidney disease patients from a phenotypic and functional point of view.

    Identify T cells and perform extensive phenotype. This analysis will be performed on mononuclear cells with a clinical flow cytometry system (panel of specific fluorophores will be used).

    Time frame: Duration of blood collection (approximately 5 minutes in inclusion)

  2. The primary outcome is to characterize T cell immunodeficiency in our cohort of end-stage kidney disease patients from a phenotypic and functional point of view.

    Perform a non-specific assessment of T-cell activation in measuring the production of ATP ( adenosine triphosphate) and cytokines.

    Time frame: Duration of blood collection (approximately 5 minutes in inclusion)

  3. The primary outcome is to characterize T cell immunodeficiency in our cohort of end-stage kidney disease patients from a phenotypic and functional point of view.

    Functional evaluation of T cells with specific viral assessment. Differents tests will be performed after peptidic stimulations: quantification of cytokines and proliferative capacities.

    Time frame: Duration of blood collection (approximately 5 minutes in inclusion)

Secondary outcomes

  1. in-vitro proof-of-concept of T-cell engineering

    Development of mRNA delivery system to restore T-cell function in ESKD patients through T-cell therapy.

    Time frame: For each outcome, duration of blood collection (approximately 5 minutes in inclusion)

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Nov 2024 (actual). Primary completion is estimated for Dec 2026, 25 months after the start.

Of 131 non-industry observational studies under Kidney Failure, Chronic, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 62. This study's planned 25 months is below that.

Counting every sponsor, half of 150 studies reached it within 29 months; a quarter within 11 and three quarters within 62.

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.
No changes since tracking began. The registry record was last updated on Jun 25, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
