Schizophrenia – Unmet Need – Detailed, Expanded Analysis: Negative Symptoms Of Schizophrenia (US/EU)
The negative symptoms of schizophrenia, which often coexist with the positive symptoms, include diminished emotional expression (affective flattening), diminished initiation of goal-directed behavior (avolition), paucity of speech (alogia), and/or other aspects of diminished social functioning. These symptoms negatively impact patients’ functioning and quality of life. Although the schizophrenia drug market is crowded with multiple antipsychotics, few, if any, therapies are available in the United States and Europe to treat the negative symptoms of schizophrenia. Of note, AbbVie’s Vraylar (United States) and Gedeon Richter / Recordati’s Reagila (Europe) has shown some efficacy in the treatment of predominant negative symptoms, and amisulpride is specifically approved in some European countries to treat the negative symptoms. Given that a sizeable proportion of schizophrenia patients exhibit negative symptoms and the few therapeutic options in this segment, there is high unmet need and commercial opportunity for an efficacious and safe therapy to treat the negative symptoms of schizophrenia in this underserved patient segment.
