Head-to-head evidence
Paliperidone palmitate (Invega Hafyera) 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.

Paliperidone palmitate (Invega Hafyera)
Marketed by Johnson & Johnson
NCT03345342 · Phase 3 · completed
After an open-label stabilization phase, 702 participants were randomized to six-month or three-month paliperidone palmitate and treated double-blind with matching injections, including placebo injections to preserve masking. The primary endpoint was the clinical outcome of time to relapse, but the registry reports that the median was not estimable in either group and does not provide a p-value or confidence interval, so the result cannot be classified as clearly met or missed.
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).
