This is an exploratory clinical investigation. The objectives of this study are to evaluate the safety, steady-state pharmacokinetics, and efficacy of metyrosine (Demser®) for the treatment of psychosis in patients with velocardiofacial syndrome (VCFS).
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
||A Double-Blind, Placebo-Controlled, Multi-Center, Randomized Trial of the Safety and Efficacy of Metyrosine (Demser®) for the Treatment of Psychotic Disorders in Patients With Velo-Cardio-Facial Syndrome
Primary Outcome Measures:
- To evaluate the safety of metyrosine (Demser®) for the treatment of psychosis in patients with VCFS [ Time Frame: 13 weeks ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- To evaluate the efficacy of metyrosine (Demser®) for the treatment of psychosis in patients with VCFS [ Time Frame: 13 weeks ] [ Designated as safety issue: No ]

Metyrosine (250 mg capsules) were to be used at all dose levels (administered as multiples of that dosing unit). The starting dose was 250 mg/day of metyrosine. Dose escalation was to be carried out weekly for 8 weeks (up to a maximum of 8 capsules/day [2000 mg/day if metyrosine]) with dosage increments of 1 capsule/day per week. Weekly dose escalation was to stop based upon the investigator's assessment of safety, but not efficacy (i.e., dose escalation was to be forced to the maximum of 8 capsules/day assuming acceptable safety and tolerability).
Placebo Comparator: Placebo
Placebo capsules were identically matched to Metyrosine.
