Metabolomics analysis in patients with specific mitochondrial DNA mutations

Official title: Metabolomics Analysis According to the Thickness of the Retinal Nerve Fiber Layer in Patients With NOHL Mutations

Run by Hôpital Necker-Enfants Malades · NCT06682819 · Data updated 2026-11-12

This study is testing the metabolic differences in healthy people with specific mitochondrial DNA mutations linked to Leber hereditary optic neuropathy to see if they can help spot early signs of optic nerve damage.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are healthy individuals aged 18 to 60 with specific mtDNA mutations (11778, 3460, or 14484) and normal visual acuity.

Probably not a fit

Patients with a history of optic neuropathy or glaucoma, as well as those outside the specified age range or without the required mtDNA mutations, may not benefit from this study.

What this trial studies

This study investigates the metabolomic profiles of healthy individuals carrying mitochondrial DNA mutations associated with Leber hereditary optic neuropathy (LHON). It aims to identify differences in metabolomic profiles and vitamin B3 and B9 levels based on the presence of optic nerve damage as indicated by optical coherence tomography (OCT). The study will evaluate these profiles separately in men and women due to the differing prevalence of LHON. By comparing these profiles with a control group, the research seeks to establish biomarkers for early optic nerve damage.

Why it matters

Potential benefit: If successful, this study could lead to the identification of early biomarkers for optic nerve damage in patients with LHON, potentially allowing for earlier intervention.

How similar studies have gone: While the approach of using metabolomics in this context is relatively novel, similar studies have shown promise in identifying biomarkers for other conditions.
