Brief Summary:
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).

Condition or disease Intervention/treatment Phase
Velo-cardio-facial Syndrome Psychosis Drug: Metyrosine Drug: Placebo Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 2 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: 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
Study Start Date : June 2010
Actual Primary Completion Date : November 2010
Actual Study Completion Date : September 2011

Arm Intervention/treatment
Experimental: Metyrosine Drug: Metyrosine
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 Drug: Placebo
Placebo capsules were identically matched to Metyrosine.

Primary Outcome Measures :
  1. To Evaluate the Safety of Metyrosine (Demser®) for the Treatment of Psychosis in Patients With VCFS [ Time Frame: 13 weeks ]

Secondary Outcome Measures :
  1. To Evaluate the Efficacy of Metyrosine (Demser®) for the Treatment of Psychosis in Patients With VCFS [ Time Frame: 13 weeks ]
