WELTRUZA reduced total PANSS scores across all 3 doses by week 8.1*
*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
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†
†LS mean differences versus placebo: -9.75, -11.27, and -9.76 for 318 mg, 425 mg, and 531 mg, respectively (P<.0001). 3
