Effect of Glycerol Trierucate on Clinical Course of Adrenoleukodystrophy

Study of Glyceryl Trierucate and Glyceryl Trioleate (Lorenzo's Oil) Therapy in Male Children With Adrenoleukodystrophy

OBJECTIVES: I. Evaluate the clinical efficacy of combination glyceryl trierucate and glyceryl trioleate (Lorenzo's Oil) therapy in boys with X-linked adrenoleukodystrophy.

II. Compare the frequency and severity of neurological disability of study patients with untreated historical controls.

Detailed Description

PROTOCOL OUTLINE: This is an open label study. Patients must follow dietary instructions as provided by the investigator. Patients receive 2-4 tablespoons of a mixture of glyceryl trierucate and glyceryl trioleate oil once daily. Patients complete a neuropsychological scoring scale questionnaire to measure neurological disability. Patients undergo physical examinations including magnetic resonance imaging and magnetic resonance spectroscopy of the head.

Patients are followed monthly for 6 months, then every 3 months until they reach the age of 13 years or death.
