Researchers are evaluating the effectiveness, safety, and tolerability of ITI-1284 for people with agitation linked to Alzheimer's dementia. This Phase 2, multicenter, randomized, double-blind, placebo-controlled study aims to compare ITI-1284 to a placebo in patients aged 55 years and older who meet specific criteria for Alzheimer's disease and agitation. Participants will be involved in three main periods: a screening phase of up to 4 weeks to confirm eligibility; a 12-week double-blind treatment phase where patients will be randomly assigned to receive either ITI-1284 (10 mg or 20 mg) or a placebo, both given once daily as a rapidly disintegrating tablet under the tongue; and a 30-day safety follow-up period after the last dose to monitor any safety concerns. During the study, participants will undergo various assessments including agitation severity measured by the Cohen-Mansfield Agitation Inventory at Week 12. Other evaluations include cognitive testing, clinical global impressions, and monitoring for side effects. Researchers will track adherence and safety through visits and questionnaires over the total study duration, which includes screening, treatment, and follow-up.

Researchers are evaluating the long-term safety and tolerability of the drug NBI-1117568 in adults diagnosed with schizophrenia. This phase 3, global, multicenter, open-label study focuses on adults aged 18 to 65 years with a primary diagnosis of schizophrenia. The study aims to better understand how this medication performs over an extended period in this patient group. Participants will receive NBI-1117568 according to a specified dosing schedule. The treatment is administered openly, meaning both researchers and participants know the medication being given. No comparator or placebo group is mentioned, and the study primarily monitors the safety and side effects related to the drug over time. Throughout the study, participants will be closely monitored for any treatment-emergent adverse events for up to 36 months. Researchers will assess safety through regular evaluations and check participants' adherence to the protocol. The study includes careful screening and ongoing observation to ensure participant well-being and the collection of long-term safety data.

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.
