About this study
Patients in maintenance treatment for HFE hemochromatosis since at least one year will be included in a two year study period and randomized in two groups experimental and control group. Because proton pump inhibitors are widely used as chronic medication, and because they can significantly modify iron absorption, patients will be stratified according to the use of proton pump inhibitors and gender. A first bloodletting will be performed at inclusion with the same volume as usually performed by the patients. Results of the biological test performed at this visit will guide the time schedule and volume of the next bloodletting according to randomization group (patients treated with bloodletting according to current guidelines "ferritin alone" versus patients treated with bloodletting according to "transferrin saturation and serum ferritin").Blood count and iron metabolism parameters will be performed at each bloodletting and follow-up visits. Time schedule and volume of bloodletting will be adjusted to biological results after each follow-up visit. Volume and schedule for bloodlettings will be determined according to guidelines specifically designed for this study to assure harmonization of treatment management, and centrally validated through the recording of the biological tests in the electronic Case Report Form which will provide the investigator with the volume and schedule of the next bloodletting. There will be two ways of treatment modification: either change of schedule or volume of bloodletting. Patients will undergo follow-up visit every six months with clinical examination, questionnaires at J0, M12 and M24 (SF-36; AIMS2-SF, WOMAC, EQ-5D-5L), and biological test. For health economics analysis, data will be obtained thanks to a dedicated extraction from SNDS database SNDS database will allow to gather hospital stays, visits, and other healthcare-related costs as well as vital status (date (month/year) of death) and cause of death. A de-identified copy of the clinical database, restricted to the relevant variables, will be sent for semideterministic matching purpose with SNDS extraction using four key variables: gender, same date (month/year) of birth, same date (day/month/year) of visit for bloodletting; pending, of course, regulatory authorization.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Clinical examinationOther
Clinical data will be recorded (general clinical examination, height, weight, blood pressure,heart beat, alcohol and tobacco consumption, antecedent) as well as concurrent medication at each follow-up visit.
SF36 questionnaireOther
At D0, M12 and M24. This 36 item patient reported survey of patient's health is the most commonly used and validated health survey instrument for appraising quality of life.
Items are grouped in 8 scaled scores exploring multiple dimension of global health (vitality, physical functioning, bodily pain, general health, perceptions, physical role functioning, emotional role functioning, social role functioning, mental health).
Scoring will be performed as recommended by the SF-36 instruction manual to create the eight scale scores. Furthermore, these subscales sum to obtain the total SF-36 score and will be summarized into two composite scores (physical and mental quality of life).
AIMS2_SF questionnaireOther
At D0, M12 and M24. The Arthritis Impact Measurement Scales 2 Short Form (AIMS2-SF) is a specific tool to measure changes in global health, pain, mobility and social function in patients with arthritis. It was described in 1992 in patients with rheumatoid arthritis and osteoarthritis and include 26 items that are summarized in scales according to a predefined scoring system: mobility, physical activity (walking, bending, lifting), dexterity, household activity (managing money and medications, housekeeping), social activities, activities of daily living, pain, depression, and anxiety. The French translation has been validated and this questionnaires has been widely used in the rheumatology field to assess quality of life of patients with arthritis. Because HFE related arthropathy is very similar to osteoarthritis this questionnaire is ought to be adequate in this setting.
WOMAC questionnaireOther
At D0, M12 and M24. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is a widely used questionnaires specifically assessing lower limb (hips and knee) osteoarthritis. It measures five items for pain, two for stiffness and 17 for functional limitation and had been translated in French.
EQ-5D-5L questionnaireOther
At D0, M12 and M24. The EQ-5D is a standardized instrument which evaluates the generic quality of life (http://www.euroqol.org/). It is a preference-based health-related quality of life measure with one question for each of the five dimensions that include mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The answers given to EQ-5D permit to find 243 health states that can be converted into utility score anchored at 0 for death and 1 for perfect health. EQ-5D is an instrument developed in Europe, widely used in cost-utility analysis. It has been validated in a representative sample of French population.

Bloodletting - control groupProcedure or surgery
Patients treated with bloodletting according to current guidelines (ferritin alone). Patient will undergo bloodletting with a goal of maintaining a serum ferritin equal or lower than 50 g/L according to current clinical practice guidelines (French and European).A first bloodletting will be performed at inclusion with the same volume as usually performed by the patients.Results of the biological test performed at this visit will guide the time schedule and volume of the next bloodletting according to randomization group. Time schedule and volume of bloodletting will be adjusted to biological results after each follow-up visit.
BioBankBiological
Blood sample will be collected for BioBank at D0, M12 and M24.
Medico-economicalOther
Medico-economic data will be collected at each follow up visit.
Bloodletting - experimental groupProcedure or surgery
Patients treated with bloodletting according to "transferrin saturation and serum ferritin". Patients will undergo bloodletting with a goal of maintaining a serum transferrin saturation equal or lower than 50 % and a serum ferritin lower than the upper limit of the normal range (300 g/L for men and 200 g/L for women).A first bloodletting will be performed at inclusion with the same volume as usually performed by the patients.Results of the biological test performed at this visit will guide the time schedule and volume of the next bloodletting according to randomization group. Time schedule and volume of bloodletting will be adjusted to biological results after each follow-up visit.

This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The primary evaluation criteria is the Physical Component Score of the SF-36 questionnaire at the end of the study period (two years) (time frame: At Month 24). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2026.
