Head-to-head evidence
Perseris vs Ziprasidone
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.
Ziprasidone
Marketed by Pfizer and partners
NCT00159770 · Phase 3 · completed
The study used randomization and active comparators but was open-label, with 290 participants, and its primary clinical endpoint was PANSS symptom change. No results are posted, so the primary endpoint cannot be classified as met or missed.
Next expected readout: February 2027 · NCT03781115 (registry estimate)
