Head-to-head evidence
Lurasidone vs Olanzapine (Zyprexa)
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.

Lurasidone
Marketed by Sumitomo Pharma
NCT00549718 · Phase 3 · completed
The study randomized approximately 500 participants to lurasidone 40, 80, or 120 mg or placebo and used quadruple masking of participants, clinicians, investigators, and outcome assessors. Its clinical primary endpoint, change in total PANSS score over 6 weeks, favored lurasidone overall versus placebo and was statistically significant (p<0.05).
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)
