Study summary

985 / 5000 Résultats de traduction Primary hyperoxaluria is a rare autosomal recessive disease with an estimated prevalence of around 1 to 3 cases per million population. The most frequent attacks are urolithiasis disease and nephrocalcinosis, ultimately leading to end-stage chronic renal failure. The phenotype of this pathology is very heterogeneous, making the diagnosis difficult.

There is currently a significant diagnostic delay. This is potentially due to atypical forms, or to insufficient clinicians' awareness of its research.

However, the early diagnosis of this pathology is essential, since end-stage chronic renal failure can be avoided or at least delayed with early and appropriate management.

The objective of the study is to describe the phenotype of currently diagnosed primary hyperoxaluria, in order to identify the classic presentations but also the characteristics of atypical presentations

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 Nov 4, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
