Patients’ symptoms were evaluated on the Positive and Negative Syndrome Scale (PANSS), a clinician-rated tool used to assess schizophrenia symptoms.2
Positive symptoms2
- Delusions
- Hallucinations
- Disorganized thoughts
Negative symptoms2

- Emotional withdrawal
- Reduced speech
General psychopathology2
- Anxiety
- Depression

WELTRUZA reduced total PANSS scores across all 3 doses by week 81
*In an 8-week, randomized, double-blind, placebo-controlled study, WELTRUZA met the primary endpoint of change from baseline in PANSS total score at week 8 versus placebo. The least squares (LS) mean changes from baseline to week 8 with WELTRUZA were -21.91, -23.44, and -21.93 for 318 mg, 425 mg, and 531 mg, respectively, versus -12.17 for placebo.3

In an 8-week, randomized, double-blind, placebo-controlled study, WELTRUZA met the primary endpoint of change from baseline in PANSS total score at week 8 versus placebo1
The least squares (LS) mean changes from baseline to week 8 with WELTRUZA were -21.91, -23.44, and -21.93 for 318 mg, 425 mg, and 531 mg, respectively, versus -12.17 for placebo3
The LS mean differences in change from baseline to week 8 versus placebo were -9.75, -11.27, and -9.76 for 318 mg, 425 mg, and 531 mg, respectively (P <.0001)3,4*
Placebo patients were switched over to active drug in the open-label safety extension phase3
PANSS score change from open-label safety extension baseline to end of study was -7.2 points4†
*Difference (drug minus placebo) in least squares mean change from baseline. For PANSS, a negative value for the difference may represent improvement.3
