Lurasidone vs Paliperidone (Invega)
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).
Paliperidone (Invega)
Marketed by Johnson & Johnson
NCT00077714 · Phase 3 · completed
The study was randomized and double-blind, but it enrolled only 12 participants and the registry does not clearly identify a comparator arm. Its primary endpoint was a clinical symptom measure (PANSS), but whether it was met cannot be determined because results are not posted.
Next expected readout: September 2027 · NCT04478838 (registry estimate)
