Study summary

Observational study.

Read the detailed description

The linked HFE genetic hemochromatosis (C282Y mutation in the homozygous state) is the most common form of genetic iron overload.

Its treatment is based on bloodletting, and takes place in 2 phases, according to the recommendations of the High Authority of Health (HAS). The first phase, called induction, aims to achieve ferritinemia \<50 by performing weekly bleeds.

The second phase, called maintenance, aims to maintain this ferritinemia \<50 by performing bleeding every 1 to 6 months depending on the case.

The treatment is therefore according to the current recommendations only adapted according to ferritinemia, and not according to the effectiveness on the functional symptoms. However, some patients report persistent asthenia during maintenance treatment, despite ferritin levels \<50. This could reflect an incomplete control of their disease, and leads us to raise two points:

  • It is known that in some subjects, the Transferrin Saturation Coefficient remains high, despite ferritinemia \<50; it is also known that this elevation of the Transferrin Saturation Coefficient may be accompanied by a rise in circulating free iron, which is toxic for the organism1.
  • The asthenia observed in some patients in the maintenance phase could be linked to a high rate of Transferrin Saturation Coefficient.

Our objective is to evaluate, in patients homozygous C282Y in maintenance phase, the association between quality of life and Transferrin Saturation Coefficient .

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 Jul 31, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
