25. Mai 2021 aktualisiert von: Shire

A Phase 2, Multicenter Study With Open-label & Randomized Double-blind Placebo-controlled Withdrawal Phases to Evaluate the Efficacy, Safety, & Tolerability of SPD489 in Adults With Schizophrenia & Predominant Negative Symptoms Who Are Clinically Stable & Taking Stable Doses of Atypical Antipsychotic Medication

To explore the efficacy of SPD489, as adjunctive therapy to a stable dose of atypical antipsychotic medication, on negative symptoms in adult subjects with clinically stable schizophrenia and predominant negative symptoms, as measured by the Scale for the Assessment of Negative Symptoms (SANS).
