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 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 conducting a multicenter, randomized, double-blind, placebo-controlled Phase 2 study to evaluate the safety and effectiveness of ACP-204 in adults with Lewy Body Dementia Psychosis (LBDP). Participants eligible for this study are adults aged 55 to 84 years who meet specific clinical criteria for Parkinson's disease dementia or probable dementia with Lewy bodies, along with psychosis criteria established for neurocognitive disorders. Participants will be assigned to receive either ACP-204 or a placebo, each provided as one capsule taken orally once daily for six weeks. This parallel-group study maintains blinding to ensure unbiased assessment of the treatment effects over the 6-week period. During the study, researchers will monitor changes from baseline in the SAPS-LBDP total score at Week 6 to assess psychosis symptoms. Participants will undergo various evaluations and assessments to ensure safety and adherence throughout the study duration, with detailed criteria guiding enrollment and exclusion to maintain participant well-being.

Researchers are evaluating lumateperone as an additional treatment for adults aged 18 to 65 with major depressive disorder (MDD) who have not responded adequately to current antidepressant therapy. This phase 3, multicenter, randomized, double-blind, placebo-controlled study aims to assess the effectiveness and safety of lumateperone in patients diagnosed according to the DSM-5 criteria, including those with psychotic features. Participants must have moderate to severe depression and an ongoing major depressive episode lasting between 12 weeks and 18 months. Participants will be randomly assigned to receive either lumateperone 42 mg capsules or matching placebo capsules once daily during a six-week double-blind treatment period. Before treatment, there is a screening period of up to two weeks to confirm eligibility. After the treatment phase, there is a one-week safety follow-up visit to monitor participants after completing the study medication. Throughout the study, patients will be assessed using depression rating scales including the Montgomery-Asberg Depression Rating Scale (MADRS). Other evaluations include psychiatric interviews, symptom questionnaires, and safety monitoring for suicidal thoughts or behaviors. The study tracks changes in depression severity and safety outcomes from screening through treatment and follow-up, totaling approximately nine weeks of participation.

This research aims to evaluate the long-term safety, tolerability, and effectiveness of NMRA-335140 in adults with major depressive disorder (MDD). It involves participants who completed earlier Phase 3 studies of NMRA-335140 for MDD and met specific eligibility and consent requirements. The study provides an opportunity to extend treatment and monitor outcomes over a longer period. Participants will receive NMRA-335140 at a dose of 80 mg taken orally once daily for a 52-week treatment period. This open-label extension allows continued assessment beyond the initial parent studies, focusing on sustained safety and effectiveness of the medication. Throughout the 52 weeks, researchers will monitor participants for treatment emergent adverse events and use validated clinical scales to assess safety and tolerability. The study's total duration for participants is up to 54 weeks, including safety assessments. Data collected will help understand the long-term effects of NMRA-335140 in managing MDD.
