Application of zileuton (Zyflo CR) in patients with Sjögren Larsson Syndrome - Zileuton in Sjögren Larsson Syndrome

Phase 1
Conditions
Sjögren Larsson syndrome (SLS) is an autosomal recessive inherited neurometabolic disorder which is characterized by a clinical triad of congenital ichthyosis, spastic di- or tetraplegia and mental retardation. A disturbance of lipid metabolism due to deficiency of the microsomal fatty aldehyde dehydrogenase (FALDH) underlies SLS.

Primary Outcome Measures
NameTimeMethod
Main Objective: To investigate the effect of Zileuton on the clinical parameters pruritus, ichthyosis as well as on the urinary concentrations of LTB4 and its metabolite omega-OH-LTB4.;Secondary Objective: Secondary, we study pharmacokinetic and pharmacodynamic properties of zileuton in humans as well as the dosage-effect relationship.;Primary end point(s): Clinical endpoints: Decrease in severity of pruritus and excoriations as well as improvement of ichthyosis measured by visual analogue scores (VAS), Willemsen score” (both filled out by parents/caregivers) as well as the clinical Sjögren Larsson Area Severity Index (SLASI). Decrease in the amount of topical emollients that is needed by the patients. <br><br>Biochemical endpoints: Significant decrease in urinary LTB4 and 20-OH-LTB4 metabolite concentrations of SLS patients during treatment with zileuton. <br>
