Head-to-head evidence
Perseris vs Quetiapine (Seroquel)
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.
Quetiapine (Seroquel)
Marketed by Cheplapharm Arzneimittel GmbH and partners
NCT00305422 · Phase 3 · completed
The study was randomized and double-blinded with an active risperidone comparator, but its small sample of 45 participants limits the strength of the evidence. The primary comparison was not reported, and the primary focus included cognitive and functional brain-activation measures rather than a clearly specified hard clinical endpoint.
