Paliperidone palmitate (Invega Hafyera) vs Paliperidone palmitate (Invega Trinza)
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.
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.
