MeasureTime frameDescription
Positive and Negative Syndrome Scale (PANSS) Total Score Change From BaselineBaseline, Day 28PANSS total score, sum of 30 item scores (each on a 0 to 7 scale), assesses positive and negative symptoms of psychopathology on a continuous scale from 0 (the best) to 210 (the worst). Day 28 value was calculated using last observation carried forward (LOCF). Change from baseline was calculated as Day 28 value minus baseline value.

Participant flow

Recruitment details

A total of 2 centers in the US were initiated and enrolled patients. 159 patients enrolled, of which 106 randomized

Pre-assignment details

Patients were screened up to 21 days, and admitted to the Clinical Research Unit (CRU) for a maximum of 2 days until eligibility was determined. Once eligibility was determined, patients currently on medication entered a 7 days washout period, patients not currently on medication had a 3 day washout, prior to randomization to study medication.
