Mild Cognitive Impairment Clinical Trials

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) Study has been to validate biomarkers for Alzheimer's disease (AD) clinical trials. ADNI4 continues the previously funded ADNI1, ADNI-GO, ADNI2, and ADNI3 studies that have combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of AD.

Development of novel disease-modifying therapies for Alzheimer's disease (AD) remains of paramount importance. This study will be a Phase II randomized clinical trial testing Senicapoc in patients with mild or prodromal AD. This will be a small Proof of Mechanism study to prove biological activity and target engagement in humans with early AD. The investigators will study up to 55 patients over 52 weeks, with primary outcomes being Alzheimer's Disease Assessment Scale Cognitive Subscale (ADAS-Cog) scores and blood and cerebrospinal fluid (CSF) markers of neuroinflammation. This pilot study will provide an estimate of treatment effect size on cognitive trajectory, daily function, and brain atrophy. Read Less

The purpose of this study is to develop an exercise treatment program for knee osteoarthritis that works well for people with memory problems. This study will include two parts. Participants can choose to participate in either or both parts. In Part 1 - The investigators are inviting the following people to participate in an interview: Individuals aged 60 years or older who do not live in a nursing home and have both memory issues and knee pain. Care partners of people with knee pain and memory issues. A care partner can be a family member or friend who helps regularly. Clinicians (exercise physiologists or rehabilitation therapists like physical and occupational therapists) who have worked with older adults with memory issues and knee pain. The goal of these interviews is to learn from the experiences of people with memory issues and knee pain and those who care for them. From these interviews, the investigators hope to design a non-drug, tailored physical activity program that will be interesting and helpful in managing knee pain for older adults with memory problems. For people with memory problems and knee pain and their care partners: The investigators will ask some questions to determine eligibility to participate in the study. Those who qualify for the study will be invited to participate in an interview that could be completed online or in person (Philadelphia, PA). The interview could last up to 90 minutes (1 and a half hours) and can be completed as one or multiple sessions. For clinicians: Participants will engage in a 90-minute focus group with other clinicians where lunch will be served if in person. Those participating in an online focus group will receive a gift card equal to the value of lunch. In Part 2 - The program developed in Part 1 will be tested. The program will be physical activity-based. Specific program details for part 2 will be provided as they emerge. Participants can choose to sign up for either or both parts. Signing up for Part 1 does not mean participants have to sign up for Part 2. Please contact us for any questions. Read Less

A recently completed study suggested that processing speed and attention (PS/A) oriented cognitive training (VSOP) produced robust effect on PS/A and working memory, but not in cognitive control or episodic memory, and long-term effects were overall modest. The proposed R01 renewal proposes to identify additional attributes to further enhance transferred and long-term effects of PS/A training in older adults with amnestic mild cognitive impairment (MCI) by addressing adaptation capacity that underpins adaptive learning and neuroplasticity. The goal of the stage II double-blinded randomized trial is to test whether adding resonance frequency breathing (RFB) training to VSOP will strengthen multiple contributors to adaptation capacity, particularly the central and peripheral pathways of autonomic nervous system (ANS) flexibility, which will strengthen VSOP training effect on cognitive and brain function and slow the progress of dementia in MCI. The central hypothesis is that strengthening adaptation capacity, via improving autonomic nervous system (ANS) flexibility, will enhance neuroplasticity and slow progress of dementia in MCI, since adaptation capacity is critical for neuroplasticity of VSOP, but compromised in neurodegenerative process. Older adults with MCI (n = 114) will be randomly assigned to an 8-week combined intervention (RFB+VSOP), VSOP with guided imagery relaxation (IR) control, and a waitlist IR control, with periodical booster training sessions at follow-ups. Mechanistic and distal outcomes include ANS flexibility and multiple markers of dementia progress. Data will be collected across a 14-month period. The two primary aims are to examine long-term effects of the combined intervention on ANS flexibility (Aim 1), as well as the cognitive, behavioral, and functional capacity (Aim 2). The exploratory aim will be to determine the preliminary long-term effect of the combined intervention on neurodegeneration. This can be a reasonable renewal plan from the completed study, aiming to identify additional attributes to further enhance transferred and long-term effects of cognitive training in MCI. This will be among the first randomized controlled trials to examine a novel, combined intervention targeting adaptation capacity in MCI, with an ultimate goal for slowing neurodegeneration. In addition, research on how to monitor adherence - the extent to which VSOP training is delivered and followed as intended - has been conceptually and methodologically limited. Robust monitoring of adherence to cognitive training requires valid assessment of effective engagement. Here, we apply our well-supported, novel framework of mental fatigability for measuring effective engagement in cognitive training. Mental fatigability, the failure to remain engaged in tasks requiring sustained mental effort, can be captured via measures of self-reported disengagement, increase in reaction time during tasks, and facial expression of negative valence/low arousal. These markers of disengagement relate to ventromedial prefrontal cortex dysfunction. We will apply this framework to advance understanding of the underpinnings of adherence to VSOP training by monitoring the extent of effective engagement while using the training platform. Read Less

The goal of this pragmatic, embedded clinical trial is to analyze the implementation of Patient Priorities Care in primary care and geriatrics clinics with patients living with dementia or mild cognitive impairment. This study aims are: demonstrate the feasibility of using the electronic health record to identify a diverse cohort of eligible patient and patient-care partner dyads who will engage in a Patient Priorities Care conversation with a trained facilitator. demonstrate feasibility of pragmatically assessing clinical outcomes using the electronic health record, including a) number of days at home, b) total medications, and c) new referrals to specialist physicians. examine key feasibility measures across racial, ethnic, and socioeconomic subgroups. Participants will receive a packet of information about Patient Priorities Care from their primary care clinic, in advance of their next upcoming clinic appointment. Individuals who receive a packet will have the opportunity to engage in a conversation about what matters most to them and what their priorities are, with trained facilitators at the clinic.

This research project is relevant to public health because both heart failure (HF) and mild cognitive impairment (e.g., trouble remembering and concentrating beyond normal aging) are highly prevalent among older adults in the United States. Despite advances in health care, there are no effective interventions for treating cognitive impairment in HF, which if left untreated, leads to suboptimal health, quality of life, and shorter survival. Therefore, the investigators propose to test the effect of a dual-component intervention comprised of a virtual reality-based cognitive restoration intervention and computerized cognitive training on cognitive function and overall health among 172 older adults with HF who experience mild cognitive impairment.

MAP will be a multisite phase II/III 1:1 randomized controlled trial (RCT) of long acting metformin (reduced mass Glucophage XR) vs. matching placebo in 326 men and women with early and late aMCI, without diabetes, not treated with metformin, overweight or obese, aged 55 years to 90 years. The RCT will last 18 months and have 4 visits: baseline, 6-months, 12-months, and 18-months. The RCT will be preceded by a screening phase followed by randomization and a titration period in which drug/placebo will be titrated from 500 mg a day (one tablet) to 2,000 mg a day (4 tablets), in increments of 500 mg (one tablet) every 10 days. Participants will remain in the RCT on the tolerated dose, and included in analyses on an intent to treat basis. We expect the attrition rate to be 10%/year. Neuropsychological battery, clinical interviews, physical exam, and phlebotomy will be conducted at baseline and every 6 months. Brain MRI will be conducted in approximately half of the participants (186) twice, at baseline, and after the last study visit at month 18. We will also conduct brain amyloid Positron Emission Tomography (PET) using 18F-Florbetaben, and tau PET using 18F-MK6240 in half of the participants at baseline and end of the RCT. The primary clinical outcome of the study will be changes in the Free and Cued Selective Reminding Test. The secondary clinical outcome will be changes in the Alzheimer's Disease Cooperative Study Preclinical Alzheimer's Cognitive Composite. Secondary subclinical outcomes will be changes in cortical thickness AD signature areas, changes in white matter hyperintensity volume, changes in brain amyloid burden, changes in brain tau burden, and changes in plasma biomarkers of amyloid, tau, and neurodegeneration. The data coordinating center and Imaging Core is located at John Hopkins University. The PET coordinating center is located at UC-Berkeley. The Clinical Coordinating and Monitoring Center and the central laboratory will be located at Columbia. The Research pharmacy function will be shared by the University of Rochester, which will dispense randomization kits, and the University of Iowa, which will receive bulk metformin and identical matching placebo from EMD Serono.

The goal of this phase II study is to establish the dose-response curves of a safe and clinically feasible non-invasive brain stimulation technique (accelerated Transcranial Magnetic Stimulation (TMS)) to improve both depression and cognitive function in Mild Cognitive Impairment (MCI) patients with comorbid depression. It is known that TMS can effectively treat depression. Identifying the right dose of accelerated TMS in MCI patients is necessary prior to designing subsequent trials to determine efficacy. These results will inform future clinical trials of accelerated TMS for MCI, with the long-term goal of developing an efficacious treatment to prevent dementia. Read Less
