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).
Risperidone (Risperdal Consta)
Marketed by Johnson & Johnson
NCT00253136 · Phase 3 · completed
This was a randomized, double-blind, placebo-controlled trial with 458 participants, using change in a standard psychiatric symptom scale as the primary measure. The FDA product label for this pivotal trial reports that 47% of patients on the 25 mg dose showed a clinically meaningful improvement, compared with 17% on placebo.
