Head-to-head evidence
Lurasidone vs Ziprasidone
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.

Shared mechanism: Dopamine D2 and serotonin 5-HT2A receptors (antagonist) · full Schizophrenia pipeline
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).
Ziprasidone
Marketed by Pfizer and partners
NCT00159770 · Phase 3 · completed
The study used randomization and active comparators but was open-label, with 290 participants, and its primary clinical endpoint was PANSS symptom change. No results are posted, so the primary endpoint cannot be classified as met or missed.
Next expected readout: February 2027 · NCT03781115 (registry estimate)
