Head-to-head evidence
Risperidone (QUAR) vs Risperidone (Uzedy)
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.

Risperidone (QUAR)
Developed by Laboratorios Farmacéuticos Rovi, S.A.
NCT06276361 · Phase 1 · completed
A sequential, open-label pharmacokinetic study of quarterly-injection risperidone in 58 participants, with pharmacokinetic parameters as the primary measures. The design is uncontrolled for treatment effect and no results have been posted to the registry, so this is weak evidence.
Next expected readout: December 2027 · NCT07047651 (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)
