Head-to-head evidence
Loxapine (Adasuve) 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.

Loxapine (Adasuve)
Marketed by Lee's Pharmaceutical
NCT00628589 · Phase 3 · completed
The trial randomly assigned 344 participants to inhaled loxapine 5 mg, loxapine 10 mg, or placebo and used quadruple blinding of participants, care providers, investigators, and outcome assessors. Its primary clinical agitation measure was significantly improved with both loxapine doses compared with placebo (p=0.0004 and p<0.0001).
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.
