Researchers are evaluating the safety and effectiveness of KarXT in preventing relapse of psychosis symptoms in people aged 55 to 90 years who have psychosis associated with Alzheimer's Disease. This Phase 3 study is randomized, double-blind, placebo-controlled, and conducted at multiple outpatient centers. The main goal is to compare relapse prevention between KarXT treatment and placebo over 38 weeks, while also assessing time to discontinuation, safety, and tolerability. Participants receive either KarXT in varying doses (ranging from 20 mg/2 mg to 66.7 mg/6.67 mg taken three times daily) or placebo capsules. The study lasts 38 weeks, during which participants remain on assigned treatment in an outpatient setting. The randomized, double-blind design ensures neither participants nor researchers know who receives KarXT or placebo during the study. Throughout the study, participants will visit the clinic regularly for assessments of their psychosis symptoms, safety checks, and overall health. Researchers will track the time to relapse of psychosis symptoms as the primary outcome. They will also monitor safety and tolerability through clinical examinations and other evaluations. The total duration of participation is 38 weeks from randomization to the end of the study period.

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 effectiveness, safety, and tolerability of ITI-1284 compared to a placebo in treating psychosis associated with Alzheimer's disease. This Phase 2, multicenter, randomized, double-blind, placebo-controlled study focuses on patients aged 55 and older who meet specific clinical criteria for Alzheimer's disease and psychosis. The study aims to assess changes in psychosis symptoms using the BEHAVE-AD psychosis subscale score after 6 weeks of treatment. Participants will be randomly assigned in equal numbers to receive either ITI-1284 or a placebo. ITI-1284 is administered as a rapidly disintegrating tablet taken once daily under the tongue at doses of 10 mg or 20 mg. The study includes three periods: up to 4 weeks of screening to determine eligibility, a 6-week double-blind treatment phase where participants receive their assigned medication, and a 30-day safety follow-up after the last dose to monitor any adverse effects. During the study, participants will undergo assessments to confirm Alzheimer's disease diagnosis and psychosis presence, including biomarker tests, clinical rating scales, and cognitive evaluations. Caregivers will be involved as designated support persons. Researchers will monitor symptom changes, safety, and tolerability throughout the treatment and follow-up periods. The primary outcome is the psychosis subscale score measured at week 6, with safety follow-up visits approximately 30 days after treatment ends.

Researchers are evaluating the safety and effectiveness of KarXT in adults aged 55 to 90 who have mild to severe Alzheimer's Disease (AD) accompanied by moderate to severe psychosis related to AD. This phase 3 study aims to better understand how KarXT compares to a placebo in treating the psychotic symptoms associated with Alzheimer's Disease. Participants must have documented AD diagnosis and a history of psychotic symptoms lasting at least two months prior to starting the study. Participants will receive either KarXT or a placebo, with specified doses given on designated days. The study is designed as a randomized, double-blind, placebo-controlled trial with parallel groups to assess the treatment's effects. Details about dosing schedules and administration are planned but not specified here. During the study, researchers will measure changes from baseline in the Neuropsychiatric Inventory-Clinician: Hallucinations and Delusions (NPI-C: H+D) score up to week 14 to evaluate the impact on psychosis symptoms. Participants will undergo brain imaging (MRI or CT) if not already done within the past five years to rule out other conditions, and safety monitoring including laboratory tests will be conducted. The total participation duration covers screening through at least 14 weeks of treatment and assessment.

Researchers are evaluating the effectiveness of NBI-1065845 compared to a placebo as an additional treatment to delay the return of depressive symptoms in adults with Major Depressive Disorder (MDD). This phase 3 study focuses on participants who have had moderate to severe recurrent MDD or persistent depressive disorder and have not responded adequately to oral antidepressant treatments. The goal is to maintain the positive effects of treatment and prevent relapse over a period of up to approximately 32 months. Participants receive either the study drug NBI-1065845 or a placebo in oral tablet form, both given alongside their ongoing oral antidepressant medications. They must continue their current antidepressant treatment at the same dose and frequency throughout the study. The study is randomized, double-blind, and placebo-controlled to ensure reliable comparison between the treatments. During the study, participants are monitored from the time of randomization until relapse or the study end, which may last up to 32 months. Researchers assess the time it takes for depressive symptoms to return, using measures such as the Hamilton Depression Rating Scale. Participants are expected to comply with all study procedures and restrictions, and safety monitoring is conducted throughout the study period.

Researchers are evaluating ACP-204, a drug that blocks a specific serotonin receptor, in adults aged 55 to 95 with Alzheimer's Disease Psychosis (ADP). The study is designed as a master protocol with three independent, multicenter, randomized, double-blind, placebo-controlled trials. The trials include Phase 2 and Phase 3 studies to assess the drug's effectiveness and safety in treating psychotic symptoms associated with ADP. The research involves three substudies. Substudy 1 (Phase 2) tests two doses of ACP-204, 30 mg and 60 mg, against a placebo to evaluate dose response. Substudies 2A and 2B (both Phase 3) will independently confirm the effects of either both doses or a single dose from Part 1 compared to placebo. Each substudy includes a screening period of up to 49 days, a six-week double-blind treatment phase, and a 30-day safety follow-up for those not continuing into an open-label extension. Vital status follow-up is conducted for participants who end the study early. Participants will receive regular assessments, including evaluations of psychotic symptoms using the Scale for the Assessment of Positive Symptoms-Hallucinations and Delusions subscales from baseline to Week 6. Other study involvement includes brain imaging scans and biomarker tests to confirm Alzheimer's disease diagnosis, cognitive testing, and monitoring of safety and vital status throughout the study periods. Stable living arrangements and support from a caregiver are required to complete all study visits.

Researchers are evaluating the long-term safety and tolerability of adjunctive KarXT, a combination of xanomeline and trospium chloride, in adults aged 18 to 65 with schizophrenia who did not have sufficient symptom control with their current antipsychotic medications. This Phase 3, open-label extension study involves participants who previously completed the treatment period of the ARISE study (KAR-012). The goal is to monitor how well patients tolerate KarXT over an extended period while assessing related safety concerns. Participants receive fixed doses of KarXT capsules twice daily, with doses ranging from 50 mg/20 mg up to 125 mg/30 mg. The study lasts for 52 weeks as an outpatient program. This open-label extension allows researchers to observe the effects and safety of KarXT when added to stable antipsychotic treatment under real-world conditions. During the study, researchers closely monitor participants for any treatment-emergent adverse events from the initial dose through a safety follow-up visit at 54 weeks or early termination. Participants will undergo regular assessments, including clinical evaluations and reports from reliable caregivers who assist with study activities. The study ensures participants maintain stable living situations and continue their background antipsychotic medications throughout the study period.

Researchers are evaluating the safety, tolerability, effectiveness, and how the body processes the drug masupirdine compared to a placebo in treating agitation in people with Alzheimer's type dementia. This Phase 3 study involves participants diagnosed with this form of dementia who also have confirmed agitation symptoms. The study is designed as a multicenter, randomized, double-blind, placebo-controlled trial. Participants will receive either masupirdine at doses of 50 mg or 100 mg, or a matching placebo tablet, taken orally once daily for 12 weeks. The study includes a screening period of about 4 weeks before randomization to determine eligibility. Treatment will start from Day 1 and continue through Day 85. During the study, researchers will assess agitation using the Cohen-Mansfield Agitation Inventory from the start until the Week 12 visit. Approximately 375 participants will be enrolled across about 50 sites worldwide. Assessments will include monitoring safety, tolerability, and pharmacokinetics throughout the treatment period to understand the drug's effects and participant responses.

The trial investigates the long-term safety and tolerability of KarXT in people with psychosis associated with Alzheimer's Disease. This Phase 3 global, multicenter, open-label extension study lasts 52 weeks and enrolls participants who have completed earlier related studies (CN012-0026, CN012-0027, or CN012-0056). The purpose is to monitor how well patients tolerate KarXT over an extended period and to collect safety data. Participants receive KarXT in varying doses taken three times daily, ranging from 20/2 mg up to 66.7/6.67 mg per dose, corresponding to total daily doses between 60/6 mg and 200/20 mg. This treatment is provided throughout the 52-week open-label extension. The study includes only those who completed the previous related studies and continues to assess their response to KarXT over this longer timeframe. During the study, participants are closely monitored for treatment-emergent adverse events from the first dose through 14 days after the final dose, which may be up to 54 weeks. Regular assessments ensure safety and tolerability, and caregivers are involved to support participants. The study also evaluates participants' ability to continue living in their current setting and requires consent from the participant or their legal representative. Overall, the study tracks long-term safety outcomes in this specific patient group.

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.
