Head-to-head evidence
Perseris vs Risperidone (Risperdal)
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.
Schizophrenia
Shared mechanism: Dopamine D2 and serotonin 5-HT2A receptors (antagonist) · full Schizophrenia pipeline
Perseris
Marketed by Indivior Pharmaceuticals, Inc.
NCT02109562 · Phase 3 · completed
This was a randomized, double-blind, placebo-controlled trial with 354 participants and a clinical primary endpoint measuring change in PANSS total score. The primary endpoint was met for both RBP-7000 doses: PANSS scores improved significantly more than with placebo.
Risperidone (Risperdal)
Marketed by Johnson & Johnson
NCT00253136 · Phase 3 · completed
The study randomized 458 participants to double-blind risperidone or placebo, with change in the clinical PANSS score as the primary endpoint. Because the registry does not report whether this endpoint was met, the trial provides a well-controlled design but no assessable result.
Next expected readout: December 2026 · NCT06482554 (registry estimate)
