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.

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).
Next expected readout: December 2027 · NCT07047651 (registry estimate)
