The trial was randomized and quadruple-blind, included both placebo and active control groups, and enrolled 593 participants. Its primary clinical symptom endpoint was PANSS-T change, with mean changes of -12.0 for iloperidone versus -7.1 for placebo, but statistical significance of the comparison is not reported, so the result remains unclear.

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).
