About this trial

This is an interventional treatment trial for Safety Issues focused on measuring leber herediatry optic neuropathy, befizal

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Adult patients in whom the diagnosis of LHON obtained on anamnestic, clinical and ancillary testing / laboratory data. LHON should have occurred for less than 5 years and must be genetically proved with a 3460 or 11778 mitochondrial DNA mutation. Given the mode of transmission, genetic research may have been carried out in a maternal relative

Exclusion Criteria:

  • * Any optic neuropathy for which the diagnosis of LHON is not formally confirmed or genetically proven;

    • LHON that started for more than 5 years;
    • LHON associated with another primary mutation than 3460 or 11778
    • Children or adult patients under guardianship or deprived of liberty by administrative or judicial decision;
    • Women of childbearing age ; pregnant or lactating women;
    • Patients who do not have affiliation to a social protection scheme (national or private insurance / beneficiary or assignee);
    • Patient who did not give its written, informed and signed consent;
    • Allergy to fibrate, bezafibrate and / or BEFIZAL® 200mg (Arrow Generiques) or one of these constituents;
    • Photosensitivity reactions related to fibrates;
    • Patient already receiving treatment with fibrates or HMG Co-A reductase inhibitors or anticoagulants;
    • Hepatic insuffisiency or dysfunction with increased of transaminases (AST and ALT) over 3 times of the normal;
    • Renal insufficiency with serum creatinine> 15 mg / L (> 135 mg / dL) Biliary pathology
