Head-to-head evidence
Asenapine vs Loxapine (Adasuve)
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.

Shared mechanism: Dopamine D2 and serotonin 5-HT2A receptors (antagonist) · full Schizophrenia pipeline
Asenapine
Marketed by AbbVie and partners
NCT00212784 · Phase 3 · completed
This 52-week trial randomly assigned 1,225 people with schizophrenia to asenapine or to olanzapine, with participants, carers, investigators and outcome assessors all unaware of assignment. The primary measure was change in total PANSS symptom score. Asenapine improved symptoms by 21.0 points against 27.5 points for olanzapine, a difference favouring olanzapine at p<0.0001, so asenapine was less effective than its active comparator on this measure.

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).
