61 Clinical Trials for Various Conditions
This project will test the hypotheses that people with 5-HT RBD have systemic alpha- synuclein pathology, prodromal DLB signs, and brainstem lesions in regions that control REM sleep. AIM 1 will seek to detect abnormally phosphorylated alpha- synuclein aggregates on targeted skin biopsy in a cohort of people with 5-HT RBD and matched controls (taking SSRIs but without RBD). Aim 2 will use ultra-high field MRI at 7T to examine the pontine region of the coeruleus/subcoeruleus complex for evidence of neurodegeneration as well as segment and parcellate REM sleep related neuronal structures. Aim 3 will test for speech deficits. While these aims are independent we suspect that the severity of autonomic, speech and cognitive deficits will correlate with loss of neuromelanin signal on MRI and pathology on skin biopsy. The investigation is a longitudinal designed study to examine histopathology, neuroimaging changes and speech function from baseline (Time 1) to a follow-up after 30 months (Time 2). A total of 60 individuals, 30 with 5-HT RBD and 30 controls, will be recruited at Time 1, brought back at Time 2, and tested across all Aims at both study visits.
This study will enroll participants with idiopathic REM sleep behavior disorder (RBD) and healthy controls for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies.
This study will evaluate the safety, biomarkers, and efficacy of tominersen compared with placebo in participants with prodromal and early manifest Huntington's Disease (HD).
The focus of this work is the evaluation of a measure of cognitive functioning- intra-individual variability (IIV) - derived from a computer-based continuous reaction time (RT) task (Cogstate) as an early marker of prodromal MS.
The purpose of this study is to evaluate the safety, tolerability, immunogenicity, pharmacokinetics, and pharmacodynamics of multiple-ascending intravenous (IV) doses of RO7126209 in participants with prodromal or mild to moderate Alzheimer's disease (AD), who are amyloid positive based on amyloid positron emission tomography (PET) scan.
The study aims to compare tau targeted radiotracers \[18F\]GTP1 and \[18F\]PI-2620 or \[18F\]MK-6240 in subjects with normal cognition or prodromal to moderate Alzheimer's disease (AD).
The purpose of this study is to assess the effects of non-invasive brain stimulation on memory in cognitively unimpaired older adults and in patients amnestic mild cognitive impairment (aMCI) due to Alzheimer's disease (AD). This study will use repetitive Transcranial Magnetic Stimulation (rTMS) to stimulate nodes of the Default Mode Network (DMN)- which is thought to support episodic memory and to be affected by Alzheimer's pathology. We will use functional connectivity MRI (fcMRI) to assess changes in functional network architecture following the stimulation. We will also assess putative cognitive improvements resulting from the stimulation by in-depth memory testing.
Interventions that affect many different aspects of human ability rather than just one aspect of human health are more likely to be successful in preventing and treating Alzheimer's disease (AD). Functional decline in AD is severely impacted by impaired ability to do physical actions while having to make decisions and concentrating, something scientists call motor-cognitive integration. Combined motor and cognitive training has been recommended for people with early AD, thus this study will use partnered, rhythmic rehabilitation (PRR), as an intervention to simultaneously target cardiovascular, social and motor-cognitive domains important to AD. PRR is moderate intensity, cognitively-engaging social dance that targets postural control systems, involves learning multiple, varied stepping and rhythmic patterns, and fosters tactile communication of motor goals between partners, enhancing social interaction's effect on cognition. Previous research demonstrates that PRR classes are safe and result in no injurious falls. This study is a 12-month long Phase II single- blind randomized clinical trial using PRR in 66 patients with early AD. Participants with early AD will be randomly assigned to participate in PRR or a walking program for three months of biweekly sessions, followed by nine months of weekly sessions of PRR or walking. The overarching hypothesis is that PRR is safe, tolerable and associated with improved motor-cognitive function, and brain (neuronal), vascular (blood vessels) and inflammatory biomarkers that might affect function.
This study will enroll participants with idiopathic rapid eye movement (REM) sleep behavior disorder (RBD), for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies.
This was a phase II, randomized, placebo-controlled, double-blind study to evaluate the efficacy and safety of Semorinemab in participants with prodromal to mild Alzheimer's disease. An optional 96-week open-label extension period was available to participants who completed the double-blind treatment period and who, in the judgment of the investigator, would potentially benefit from open-label Semorinemab treatment.
This randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of crenezumab versus placebo in participants with prodromal to mild AD. Participants will be randomized 1:1 to receive either intravenous (IV) infusion of crenezumab or placebo every 4 weeks (Q4W) for 100 weeks. The primary efficacy assessment will be performed at 105 weeks. The participants who do not enter open-label extension will enter for a long term follow-up period for up to 52 weeks after the last crenezumab dose (Week 153).
The main purpose of this study is to investigate the safety and efficacy of the study drug solanezumab in participants with prodromal Alzheimer's disease (AD).
This randomized, double-blind, placebo-controlled, parallel group study will evaluate the efficacy and safety of crenezumab versus placebo in participants with prodromal to mild AD. Participants will be randomized 1:1 to receive either intravenous (IV) infusion of crenezumab or placebo every 4 weeks (Q4W) for 100 weeks. The final efficacy and safety assessment will be performed 52 weeks after the last crenezumab dose. Participants will then have the option to enter the Open Label Extension (OLE) study if eligible. Participants who do not enter the OLE study will have additional follow-up visits at 16 and 52 weeks after the last dose, primarily for safety and also for limited efficacy assessments.
The purpose of this study is to evaluate the safety, tolerability, PK, and efficacy of Pepinemab in subjects with late prodromal and early manifest Huntington's disease.
This is a Phase 2 study to evaluate safety and efficacy in participants with Mild Cognitive Impairment due to Alzheimer's Disease/Prodromal Alzheimer's Disease (referred to as MCI/Prodromal) and mild to moderate dementia due to Alzheimer's Disease (referred to as mild to moderate AD). This study will have a Core Phase and an Extension Phase.
The purposes of this study are to investigate the safety, tolerability, and pharmacodynamics of FRM-0334 in subjects with prodromal to moderate frontotemporal dementia with granulin mutation.
The primary objective of this study is to evaluate the safety and tolerability of multiple doses of Aducanumab (recombinant, fully human anti-Aβ IgG1 mAb) in participants with prodromal or mild Alzheimer's Disease (AD). The secondary objectives of this study are to assess the effect on cerebral amyloid plaque content as measured by florbetapir-fluorine-18 (18F-AV-45F-AV-45) positron emission tomography (PET) imaging, to assess the multiple dose serum concentrations of Aducanumab and to evaluate the immunogenicity of Aducanumab after multiple dose administration in this population.
This multi-center, randomized, double-blind, placebo-controlled parallel-group study will evaluate the effect of gantenerumab (RO4909832) on cognition and functioning and the safety and pharmacokinetics in participants with prodromal Alzheimer's Disease. Participants will be randomized to receive subcutaneous (SC) injections of either gantenerumab or placebo. Participants who consent to be part of the sub study will undergo positron emission tomography (PET) scanning to assess brain amyloid. The anticipated time on study treatment is 104 weeks in Part 1, with an option for an additional up to 2 years of treatment in Part 2, followed by an open-label extension (Part 3) until July 2020. The dosing for Parts 1 and 2 was stopped after a planned futility interim analysis showed a low probability of meeting the primary outcome measure with the doses studied. The study has converted to open-label to investigate higher gantenerumab doses.
The purpose of this study is to determine the safety and tolerability of BMS-708163 in patients with Prodromal Alzheimer's disease over a treatment period of a minimum of 104-weeks. In addition patients will be seen for safety visits at 4 and 12 weeks post treatment.
We hypothesize that symptoms will improve in patients who meet diagnostic criteria for the schizophrenia prodrome when they are prescribed aripiprazole.
The primary aim of this application is to conduct a randomized, controlled clinical trial of a specialized mental health service delivery system specifically developed for prodromal psychotic disorders. The intervention is Family-aided Assertive Community Treatment (FACT). The goal of the treatment is prevention of psychosis and disability. This study will assess experimentally the clinical effectiveness of this new type of mental health service. Other domains of outcome include cognitive dysfunction and functional disability.
In this research study we want to learn more about the effects of non-invasive brain stimulation on motivation, memory, and brain-network function in cognitively unimpaired older adults and individuals with preclinical Alzheimer's disease. This study will use a form of non-invasive brain stimulation called repetitive Transcranial Magnetic Stimulation (rTMS). rTMS will slightly alter activity in an area of your brain that controls cognition. Changes resulting from this stimulation will be measured with behavioral tests, as well as by taking brain images with Magnetic Resonance Imaging (MRI). Participants will come in for one baseline visit followed by 10 days of daily rTMS study visits (Monday through Friday) and an evaluation visit. Then, there will be a 2-week break. After this break, they will return for another baseline visit, an additional 10 days of rTMS, and a final evaluation visit.
The goal of this clinical trial is to learn if a single-session digital intervention (SPARK Coping) is acceptable, usable, and demonstrates a preliminary signal of efficacy in reducing symptom-related distress and increasing positive treatment-seeking attitudes among college students reporting subthreshold symptoms associated with risk for psychosis. Research questions inclue: * Does SPARK Coping reduce symptom-related distress and increase positive treatment seeking attitudes (primary outcomes) relative to a waitlist control condition? * Does SPARK Coping increase adaptive coping and reduce internalized stigma (primary targets) relative to a waitlist control condition? Researchers will compare provision of SPARK Coping to a waitlist control condition and collect data from participants on each of the variables described above. Participants will: * Complete questionnaires and surveys remotely at the start of the study and two weeks later * Be offered access to the SPARK Coping intervention either after completion of their baseline assessment (intervention arm) or after two weeks (waitlist control arm).
The present study will assess the feasibility and social validity of an adjunctive health promotion group for youth and clinical high risk for psychosis (CHR-P). Youth participating in treatment at the Center for the Assessment and Prevention of Prodromal Sates (CAPPS) will be invited to participate in a weekly, adjunctive, closed psychoeducation group focused on sharing health promotion strategies and increasing health behaviors (e.g. improved sleep habits, increased participation in physical activity). The aim of the group will be to provide psychoeducation on lifestyle risk and protective factors for youth at risk for psychosis (i.e. experiencing subthreshold psychosis symptoms). Topics covered will include psychoeducation, goal setting, stress management, sleep, physical activity, substance use, and nutrition. Evidence-based strategies to decrease risk factors and promote protective lifestyle factors for mental illness will be reviewed. Group leaders will utilize a motivational interviewing approach to facilitate the group. The group will complete nine weekly group sessions. The goal of our research is to 1) determine the feasibility of a novel group-based health promotion intervention, 2) assess the social validity of the group, 3) measure the effects of the intervention on stress, sleep, physical activity, substance use, and nutrition, and 4) measure preliminary effects on symptoms and functioning.
Compensatory aids (e.g., alarms, calendars) play an important supporting role when completing everyday tasks (e.g., appointments, medication management), and there is a growing body of scientific work suggesting that compensatory training improves daily functioning. However, traditional paper-based calendars and to-do-lists have limitations related to accumulation of information, difficulty retrieving information, and remembering to complete activities. Such limitations may be overcome using a digital format through organized digital files, search functions, and alarms. This pilot project proposes to train older adults at risk for cognitive decline to use the Digital Memory Notebook (DMN), a tablet-based application (app), to support everyday functioning. The primary goal is to obtain preliminary evidence that a 6-week, individual and group-based DMN training intervention results in demonstrable changes in target behaviors (e.g., goal-directed DMN use to support everyday activities) among older adults with mild cognitive impairment (MCI) and subjective cognitive complaints (SCC). Participants will complete a curriculum involving 2-hour weekly sessions for 6-weeks. Each week will cover a specific function of the DMN and will include standardized goal-setting and weekly homework targets. Following the 6-week intervention, participants will continue to use the DMN app for 4-weeks to evaluate stability. Participants will complete a questionnaire packet 1 week prior to the 6-week intervention, 1 week after the 6-week intervention, and 5 weeks following the 6-week intervention. MCI and SCC participants will complete separate 6-week individual or group interventions spaced two months apart at UCD.
The Ohio State University Early Psychosis Intervention Center is implementing a specialized clinical program to serve individuals who meet clinical high risk criteria for a psychosis. The purpose of this study is to evaluate the long-term outcomes among individuals participating in this clinical service.
Community-based treatments for adolescents at risk for psychosis are not widely available, nor are there established, gold-standard psychosocial group interventions for this population. The HOPE TEAM, Helping Overcome Prodromal Experiences through Treatment and Evaluation of Adolescent Minds (PI: Bachman; funded by The Pittsburgh Foundation) is an early detection and intervention program for youth at clinical high risk for psychosis which aims to help them by engaging existing community resources, providing assessment, and offering trauma-informed psychotherapy. Embedded within the Family Care Connection Center at Turtle Creek, the HOPE TEAM offers individual psychotherapy as part of its clinical service model. The present study seeks to evaluate, in a small and preliminary sample (n = 20), the feasibility and effectiveness of a 24-week Cognitive-Behavioral Social Skills Therapy (CBSST) group intervention for CHR adolescents who are part of the HOPE TEAM. To that end, the current proposal will seek to conduct brief research assessments to assess the group members' perceptions of the group's utility, as well as their current clinical symptoms and functioning prior to, during, and after participating in this group. The goals of this pilot project are to 1) identify which aspects of the group perceived to be most and least helpful by participating adolescents, and 2) evaluate whether participation in the group meaningfully improves participants' clinical symptoms and functioning. The investigators aim to use these pilot data to guide future selection of treatment targets in this clinical practice, and to identify future strategies for increasing satisfaction and retention in community-based group interventions for CHR adolescents.
Young people who are at great risk for developing psychosis have cognitive deficits which are strongly related to functioning in the community. This study looks to target a specific cognitive skill called processing speed to see if improving the ability to process information in a timely manner will improve social function in adolescents and young adults at risk for developing schizophrenia. Half will receive neurofeedback cognitive training targeting processing speed while the other half will receive an active control.
The Recognition and Prevention (RAP) Program is conducting a research study comparing an antidepressant, sertraline, alone versus in combination with a second-generation antipsychotic, risperidone, to evaluate their ability to reduce unusual thoughts, suspiciousness and other unusual experiences, to improve reasoning ability, memory, attention and social skills in adolescents.
The RAP Program is conducting a research study of the antipsychotic medication Aripiprazole. This drug has been approved for treating symptoms associated with schizophrenia and is associated with fewer side effects. This study will explore how well Aripiprazole treats symptoms of early-onset psychotic disorders as well as symptoms that may indicate risk for such disorders, including unusual thoughts, suspiciousness, perceptual abnormalities, social isolation, and sudden changes in functioning.
