Researchers are evaluating the effectiveness and safety of KarXT for treating schizophrenia in adolescents aged 13 to 17 years. This Phase 3 study focuses on adolescents who meet diagnostic criteria for schizophrenia and experience symptoms of psychosis. The study aims to better understand how KarXT may impact symptoms as measured by a standard schizophrenia rating scale. Participants will receive either KarXT or a matching placebo at specified doses on specific days. The study is randomized, double-blind, and placebo-controlled, meaning neither the participants nor the researchers know who receives the active drug or placebo during the trial. During the study, researchers will assess changes in schizophrenia symptoms using the Positive and Negative Syndrome Scale (PANSS) after 5 weeks of treatment. Participants will be monitored for safety and symptom changes throughout the study period. The goal is to gather detailed information about KarXT's impact on schizophrenia symptoms in this adolescent population.

Researchers are evaluating the efficacy and safety of cariprazine in treating adolescents aged 13 to 17 years with schizophrenia. This Phase 3 study compares cariprazine to a placebo to understand its effects on this population. Participants must have a confirmed diagnosis of schizophrenia based on DSM-5 criteria and meet specific symptom severity requirements. Participants receive either cariprazine or matching placebo capsules once daily by mouth for 6 weeks in a randomized, double-blind, parallel-group design. The study is conducted across multiple international centers to ensure diverse participation and data collection. Throughout the 6-week study, researchers assess changes in schizophrenia symptoms using the PANSS total score from baseline to Week 6. Safety and tolerability are also monitored closely. Participants will undergo clinical evaluations and symptom scoring to track progress and response to treatment during the study period.

Researchers are evaluating how well seltorexant works and its safety as an added treatment to antidepressants in adults and elderly participants who have major depressive disorder with insomnia symptoms (MDDIS). The study focuses on people who have not responded adequately to current antidepressant therapy with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs). This Phase 3 trial aims to assess the improvement of depressive symptoms and the maintenance effect of seltorexant compared to a placebo. Participants will receive either seltorexant or a matching placebo taken orally alongside their current antidepressant medication, which includes SSRIs or SNRIs. The study is divided into two parts: Part 1 evaluates changes in depression severity after 43 days, while Part 2 monitors the time to relapse for up to nearly three years in participants who achieved a stable response. Participants must continue their stable antidepressant dose during the study. During the study, participants will be assessed using the Montgomery-Asberg Depression Rating Scale to measure changes in depression symptoms and monitored for relapse over time. Safety and tolerability will also be evaluated throughout. The total participation includes an initial treatment phase and an extended maintenance phase, allowing researchers to understand both short-term and long-term effects of seltorexant as an adjunctive therapy.

Researchers are evaluating weight gain in children and teenagers with schizophrenia or bipolar I disorder by comparing changes in body mass index (BMI) Z-score after treatment with a combination drug called OLZ/SAM versus olanzapine alone. This Phase 3 study focuses on pediatric patients aged 10 to 17 years and aims to understand how these treatments affect BMI over time. The study involves two treatment groups: one receiving OLZ/SAM, which combines olanzapine and samidorphan, and the other receiving olanzapine alone. The starting dose of olanzapine will either be 2.5 mg or 5 mg daily, based on the investigator's choice, with a maximum dose of 20 mg per day. Samidorphan doses will start at either 5 or 10 mg. Treatment lasts for up to 52 weeks under a randomized, double-blind design. Participants will be monitored through 12 weeks for changes in BMI Z-score, with ongoing assessments throughout the study. The study includes outpatient visits and requires reliable family or guardian support for managing treatment. Researchers will evaluate weight changes and monitor safety, including mental health status and potential side effects, to collect comprehensive data on treatment impact during the year-long period.
