Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

Olanzapine (Zyprexa)
Marketed by Cheplapharm Arzneimittel GmbH and partners
NCT00712686 · Phase 3 · completed
The study was a large randomized, double-blind, active-controlled comparison of aripiprazole and olanzapine, with clinical outcomes including PANSS symptom scores. Because the registry does not report whether either primary endpoint was met, the treatment comparison cannot be judged as positive, negative, or mixed.
Next expected readout: February 2027 · NCT03781115 (registry estimate)
Risperidone (Uzedy)
Marketed by Teva Pharmaceutical Industries
NCT03503318 · Phase 3 · completed
This was a randomized, quadruple-blind, placebo-controlled trial with 544 participants assigned to placebo, monthly TV-46000, or every-two-month TV-46000. The hard clinical primary endpoint was time to impending relapse, and it was statistically significantly favorable for both monthly treatment (13/183 vs 53/181; p<0.0001) and every-two-month treatment (23/179 vs 53/181; p<0.0001).
Next expected readout: December 2027 · NCT07047651 (registry estimate)
