Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)

Primary Outcome Measures:
  • To evaluate the safety of metyrosine (Demser®) for the treatment of psychosis in patients with VCFS [ Time Frame: 13 weeks ]

Secondary Outcome Measures:
  • To evaluate the efficacy of metyrosine (Demser®) for the treatment of psychosis in patients with VCFS [ Time Frame: 13 weeks ]

Enrollment: 2
Study Start Date: June 2010
Estimated Study Completion Date: September 2011
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.
