Head-to-head evidence
Paliperidone palmitate (Invega Trinza) vs Risperidone (Risvan)
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 Trinza)
Marketed by Johnson & Johnson
NCT02713282 · Phase 3 · completed
This was a single-group, open-label study without randomization or a comparator arm, so it could not directly compare the 3-month formulation with placebo or another treatment. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
Risperidone (Risvan)
Marketed by Laboratorios Farmacéuticos Rovi, S.A.
NCT03160521 · Phase 3 · completed
The study randomized 438 participants to two risperidone doses or placebo under triple masking, with 390 participants included in the reported primary efficacy analysis. The clinical primary endpoint was the change in PANSS total score, reported as -24.6 and -24.7 points with risperidone versus -11.0 with placebo, but statistical significance for this primary comparison is not stated, so the result remains unclear.
