Summary
X-linked adrenoleukodystrophy (X-ALD) is an inherited metabolic disorder characterised by
accumulation of very long chain fatty acids (VLCFA) in plasma and tissue. Presumably this
accumulation is responsible for tissue damage. The disease can cause severe demyelinisation
of the central nervous system usually causing death in childhood or progressive ambulatory
problems in adults caused by a progressive myelopathy. For the latter category of patients no
curative treatment is currently available. Recent investigations in human fibroblasts and
mice identified bezafibrate as an agent that might reduce VLCFA in patients with X-ALD.
Objective of the study:
The trial is designed as an open-label pilot study. The main goal is to investigate if
bezafibrate can reduce VLCFA in vivo in patient with X-ALD. If there is indeed a biochemical
effect, a large follow-up study will be initiated with clinical outcome parameters.
Study design:
10 men with X-ALD will use bezafibrate during a period of 6 months (in combination with a low
fat diet). On 6 different time points the participants will undergo a venipuncture for
detecting possible side effects and to determine the biochemical outcome parameters.
Study population:
Adult men with X-linked adrenoleukodystrophy.
Intervention (if applicable):
Bezafibrate.
Primary study parameters/outcome of the study:
The primary outcome parameters are cholesterol levels (total-, LDL, and HDL) and levels of
triglycerides in plasma, VLCFA levels in plasma, leukocytes and erythrocytes and also
C26:0-lyso-PC in bloodspots.
Secondary study parameters/outcome of the study (if applicable):
Secondary outcome parameters are side-effects (subjective and abnormalities in the safety
lab).
