Milsaperidone (VHX-896)
Marketed by Vanda Pharmaceuticals
NCT06494397 · Phase 1 · completed
Every participant in this trial received both VHX-896 and iloperidone, just in a different order, so there is no separate group that shows what happens without VHX-896, and nobody was blinded to which drug was being given at each stage. The trial measured drug levels in the blood to compare the two products, not any change in psychiatric symptoms, and results have not been posted yet.
Olanzapine (Zyprexa Relprevv)
Marketed by Cheplapharm Arzneimittel GmbH and partners
NCT00088478 · Phase 3 · completed
This was a randomized, double-blind, placebo-controlled trial of 402 patients. All three tested doses of the long-acting olanzapine injection produced a significantly greater reduction in psychiatric symptom severity (PANSS) than placebo.
Next expected readout: December 2027 · NCT07047651 (registry estimate)
