Disease Progression in Women With X-linked Adrenoleukodystrophy

Recruiting

• Conditions: X-linked Adrenoleukodystrophy

• Registration Number: NCT06178120
• Lead Sponsor: Minoryx Therapeutics, S.L.

Brief Summary

Observational, single-site prospective and minimally interventional study in women with X-linked adrenoleukodystrophy (ALD), conducted in France.

Detailed Description

Patients accepting participation (after signing ICF) will be followed up to at least 2 years or until they started treatment for X-linked adrenoleukodystrophy (ALD) or withdraw consent, whichever occurs first. Follow-up will be extended beyond 2 years if deemed appropriate after an interim report. Tests and questionnaires will be assessed at baseline and yearly. If the study is extended, beyond 2 years, patients will be assessed at 1-year intervals.

At baseline visit and follow-up visits, patients will undergo an MRI of the brain and the spinal cord and assessments of body sway, EDSS, ADL, pain VAS and SF-36 questionnaire. Plasma biomarkers will be assessed from samples obtained through routine blood draw and a monthly falls diary will be provided each visit to be completed once a month.

This study will not assess any specific medicinal product or intervention, and the study will not interfere with that prescribed in clinical practice.
