28 Clinical Trials for Various Conditions
This 52-week, open-label extension study is to evaluate the long-term safety and tolerability of ACP-204 in subjects with ADP.
This is a master protocol for 3 independent, seamlessly enrolling, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies in patients with ADP * Substudy 1 (Phase 2) will evaluate efficacy and dose response of ACP-204 30 and 60 mg vs placebo. This substudy will be initiated first. * Substudies 2A and 2B (both: Phase 3) will be confirmatory studies of either both doses (ACP-204 30 and 60 mg, respectively) or a single dose from Part 1 vs placebo. Substudies 2A and 2B will be performed independently of each other and will commence after enrollment of Part 1. All 3 substudies will be analyzed independently of each other. Each substudy individually will consist of a screening period (up to 49 days); a double-blind treatment period (6 weeks); a safety follow-up period (30 days) for patients not rolling over into an open-label extension study; and vital status follow-up (for patients who terminated their substudy early).
This research project aims to understand the brain mechanisms behind the manifestation of psychotic symptoms in Alzheimer´s disease (AD), and nature of the unique relationship with tau pathology. Amongst the cognitive manifestations of psychosis are impairments related to frontal circuits (social cognition, working memory and executive function deficits). The investigator's previous work suggests a role of tau pathology (one of the hallmarks of AD neuropathology) in the manifestation of psychosis in AD. However, the cerebral mechanisms that underly this association remain poorly understood. The overarching aim of the study is is to investigate the mechanisms by which tau network pathology may promote the presentation of psychosis in AD.
The purpose of this study is to evaluate the safety and efficacy of KarXT in adult participants with mild to severe Alzheimer's Disease (AD) with moderate to severe psychosis related to AD.
This is a multicenter, randomized, double-blind, parallel-group, placebo-controlled, flexible-dose study evaluating the efficacy, safety, and tolerability of ITI-1284 compared with placebo in the treatment of psychosis in patients with AD.

Clinically, many patients with AD show no response or minimal response to antipsychotics for symptoms of agitation/aggression or psychosis, or they have intolerable side effects on these medications. Antipsychotics have a wide range of side effects, including the risk of increased mortality (60-70% higher rate of death on antipsychotic compared to placebo) that led to an FDA black box warning for patients with dementia; a more recent review and meta-analysis showed a 54% increased risk of mortality. In addition, some patients show only partial response to antipsychotics and symptoms persist. For these reasons, the investigators need to study alternative treatment strategies. Currently, there is no FDA-approved medication for the treatment of psychosis or agitation in AD. The investigators innovative project will examine the efficacy and side effects of low dose lithium treatment of agitation/aggression with or without psychosis in 80 patients with AD in a randomized, doubleblind, placebo-controlled, 12-week trial (essentially a Phase II trial). The results will determine the potential for a large-scale clinical trial (Phase III) to establish the utility of lithium in these patients.
The purpose of this study is to assess acceptability, and safety of providing tDCS to ADRD patients with behavioral symptoms and to assess the efficacy of tDCS for ADRD-related symptoms, mainly behavioral symptoms.
The purpose of this study is to evaluate the safety and tolerability of multiple ascending doses of MK-8189 in participants with Alzheimer's Disease (AD) with or without symptoms of agitation-aggression and/or psychosis.
The purpose of this study is to evaluate the efficacy of pimavanserin compared to placebo in preventing relapse of psychotic symptoms in subjects with dementia-related psychosis who responded to 12 weeks of open label pimavanserin treatment.
A ten-week study to assess MP-101 in Dementia-Related Psychosis and/or Agitation and Aggression
In patients with Alzheimer's disease (AD) who respond to antipsychotic treatment of psychosis and/or agitation/aggression, the relapse risk after discontinuation is not established. AD patients with psychosis and/or agitation/aggression receive 16 weeks of open risperidone treatment (Phase A). Responders are then randomized, double-blind, to one of three arms in Phase B: (1) continuation risperidone for 32 weeks, (2) risperidone for 16 weeks followed by placebo for 16 weeks, (3) placebo for 32 weeks. The primary outcome is time to relapse of psychosis/agitation.
The CATIE Alzheimer's Disease Trial is part of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) Project. The study is for people with Alzheimer's disease who are having trouble with their thinking or behavior. In particular, this study is trying to find out the best treatment for people who have hallucinations (seeing or hearing things that aren't there), delusions (false beliefs), or agitation. The design of the trial helps to increase the chance that participants in the study receive a medication that helps them. The study uses three medications known as atypical antipsychotics (olanzapine, quetiapine, risperidone), which are the newest medications that are currently available for treating these problems. Participants may also receive an antidepressant (citalopram). The trial lasts for 36 weeks. Participants are given a thorough evaluation at no cost to ensure that this study is appropriate. In addition, the caregiver, family member, or friend who comes with the participant will be offered an educational program about Alzheimer's disease.
The optimal strategy for the treatment of behavioral complications in patients with probable Alzheimer's disease (AD) remains unclear. The objective of this study is to evaluate the risk of relapse following discontinuation of haloperidol in patients with Alzheimer's disease (AD) with psychosis or agitation who respond to it. In Phase A of this study, AD outpatients with behavioral complications receive 20 weeks of open haloperidol treatment with an oral dose of 1-5 mg daily, titrated individually to achieve the optimal trade-off between efficacy and side effects. Responders to Phase A participate in Phase B, a 24-week continuation trial in which patients are randomized to continuation haloperidol or placebo. The primary outcome is the time to relapse of psychosis or behavioral disturbance.
Agitation affects 70 to 90 percent of patients with AD. Signs of agitation include verbal and physical aggressiveness, irritability, wandering, and restlessness. These behaviors often make caring for patients at home very difficult. Trazodone and haldol are two of the most commonly prescribed drugs for agitation in AD patients. Behavior management, a non drug approach, has been effective in reducing signs of agitation. Researchers have yet to compare the effectiveness of drug versus non drug therapy to treat agitation in AD patients and determine which is the best treatment. The Alzheimer's Disease Cooperative Study, with funding from the National Institute on Aging, is conducting an agitation treatment program at 21 sites in 16 States. This study will assess which of the above treatments is most effective.
To follow-up on the safety of subjects who were previously treated in a double-blind trial of brexpiprazole.
To compare the efficacy of flexible dosing of brexpiprazole with placebo in subjects with agitation associated with dementia of the Alzheimer's type
This is a 10-week study with bifeprunox and placebo in elderly subjects with psychosis and behavioral disturbances associated with dementia of the alzheimer's type.
The purpose of this study is to determine whether an antipsychotic medication alone or an antipsychotic medication in combination with divalproex is the most effective and safest way to treat agitation in elderly patients with dementia.
The purpose of this trial is to demonstrate whether valproate therapy delays the emergence of agitation and/or psychosis in outpatients with probable Alzheimer's disease (AD) who have not experienced agitation and psychosis in their illness. A secondary aim is to determine whether valproate therapy delays the progression of cognitive and functional measures of the illness. This trial will also assess the tolerability and safety of low-dose, long-term valproate therapy. Valproate, an anticonvulsant drug, was selected because of its possible symptomatic efficacy for agitation in AD, known safety profile in numerous clinical populations, and in view of recent data supporting its neuroprotective potential in AD.
This is a Congressionally mandated study. In the original study, 16 demonstration programs provided care coordination services to beneficiaries with chronic illness in Medicare's fee-for-service program. A five-year CMS-funded study tested whether the programs can improve patients' use of medical services, improve patients' outcomes and satisfaction with care, and reduce Medicare costs. The study also assessed physicians' satisfaction with the programs. In 2008 Congress extended the project for two of the original programs--Mercy Medical Center - North Iowa and Health Quality Partners in Pennsylvania--and they will enroll Medicare beneficiaries and provide care coordination services into the spring of 2010.
This clinical trial aims to evaluate the safety and efficacy of PROSOMNIA Sleep Therapy (PSTx) for individuals suffering from chronic insomnia, sleep deprivation, and REM sleep disorders. Chronic insomnia, characterized by difficulty falling or staying asleep, significantly affects patients and quality of life, mood, and cognitive function. REM sleep disorders, in which the body struggles to enter or maintain restful REM sleep, can worsen these issues. The trial introduces a novel therapy using anesthesia-induced sleep, targeting sleep homeostasis and improving sleep architecture. Objectives: The primary goals of the trial are to determine: 1. Whether PROSOMNIA Sleep Therapy increases the quality of REM sleep. 2. Whether PSTx increases the duration of REM and/or NREM sleep. 3. Whether PSTx decreases the time it takes participants to fall asleep (sleep onset latency). Participants will receive ONE (1) PROSOMNIA Sleep Therapy session lasting between 60-120 minutes. Each session uses Diprivan/Propofol to induce sleep, and is monitored via an EEG to ensure proper sleep stages, particularly REM sleep. Participant Criteria: Inclusion: Adults aged 18-65 with diagnosed or undiagnosed chronic insomnia or sleep deprivation. Exclusion: Patients with severe obesity, significant cardiovascular, neurological, or psychiatric conditions, or those with an ASA status above II. Study Design: This trial is non-randomized, single-arm and open-label, with all participants receiving the PSTx. The trial does not include a comparison group, as the focus is on evaluating the immediate, direct effects of the therapy. Participants will undergo continuous EEG monitoring during therapy sessions, allowing researchers to track brain activity and sleep stages in real-time. This method ensures that sleep cycles, particularly REM sleep, are optimized for therapeutic benefit. Therapy Methodology: PROSOMNIA Sleep Therapy leverages anesthesia to mimic natural sleep patterns and enhance the efficiency of REM sleep. Diprivan/Propofol is used to induce REM sleep, while EEG monitoring tracks and maintains proper sleep architecture throughout the session. The therapy promotes the clearance of adenosine, a compound that builds up during wakefulness and drives the need for sleep. Adenosine is cleared during REM sleep, reducing sleep pressure and improving cognitive function. Outcome Measures: Primary Outcomes: Researchers will measure the increase in REM sleep duration, improvement in sleep quality (via self-reported questionnaires), and a reduction in sleep onset latency. Secondary Outcomes: These include changes in mood, cognitive function, and blood serum uric acid levels. Patient-reported outcomes will also be tracked through tools like the PROSOMNIA Sleep Quiz, which is specifically designed for PSTx. Significance: Chronic insomnia and REM sleep disorders affect millions globally, leading to cognitive impairment, mood disturbances, and poor overall health. Traditional treatments, including pharmacological approaches and Cognitive Behavioral Therapy for Insomnia (CBT-I), often provide suboptimal results for many individuals. PSTx offers a novel, therapeutic approach to restoring sleep balance and enhancing the overall quality of sleep, particularly for those who have not responded to conventional treatments. Study Process: Recruitment and Baseline Assessments: Participants undergo a comprehensive sleep assessment, including sleep questionnaires and polysomnography, to establish a baseline for sleep quality and duration. Blood serum uric acid levels will also be measured to track any biochemical changes due to therapy. Therapy Sessions: Only one (1) PROSOMNIA Sleep Therapy session will be administered, with the session lasting between 60-120 minutes. Diprivan/Propofol is used to induce sleep, and EEG will monitor brain activity to ensure the proper balance of sleep stages. Post-Therapy Follow-up: Follow-up assessments will occur at 24 hours, 7 days, and 30 days post-treatment. Researchers will analyze the therapy effects on REM sleep, mood, cognitive function, and other health indicators. Potential Implications: If successful, this trial could revolutionize how we treat sleep disorders by targeting the underlying mechanisms of sleep pressure and REM sleep disruption. PROSOMNIA Sleep Therapy may offer a safe, effective, and immediate alternative for patients who have exhausted other treatment options. Key Concepts: Homeostatic sleep drive, (Process S), caused by adenosine buildup during wakefulness, is disrupted by chronic insomnia. This impacts cognitive function health and recovery. Anesthesia-induced REM sleep via PSTx helps regulate this homeostatic sleep stage, offering deeper and more restorative sleep compared to other sleep therapies. The study uses statistical methods like ANOVA and Chi-square to measure outcomes.
The Self-care for Dementia Caregivers Study is a behavioral health intervention that uses digital monitoring tools and motivational health coaching to help caregivers of persons with dementia engage in a regular routine of self-care. Participants wear an apple watch for the objective collection of sleep-wake rhythms. They receive personalized feedback on their sleep-wake rhythms via a new app. Health coaches call participants weekly, for up to 6 weeks to help participants meet their health/sleep goals and promote self-knowledge of regular routines. Participants will help the study team improve the design elements and content of the mobile app. The goal of this intervention is to reduce psychological distress and caregiver burden.
