Study Details

This study is a national, non-randomized, open-label, multi-site with minimal risk study in adult with adrenomyeloneuropathy (AMN), childhood and adult subjects with cerebral ALD (cALD), juvenile/adult metachromatic leukodystrophy (MLD) and adults with leukoencephalopathy and axonal spheroids and pigmented glia (ALSP). 49 subjects will be enrolled with one blood sample collection during one of their medical follow-up visit. This trial will evaluate the role of innate immunity to influence disease progression in X-ALD, MLD and ALSP, and if the mutations related to these leukodystrophies result in a specific immune response leading to the pathogenesis.
