  1. Imaging of Brain Amyloid Plaques in the Aging Population

    Rochester, Minn.

    Imaging of Brain Amyloid Plaques in the Aging Population

    • Study type:

      Interventional What is this?

      Describes the nature of a clinical study. Types include:

      • Observational study — observes people and measures outcomes without affecting results.
      • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
      • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

    • Study phase:

      IV What is this?

      During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

    About this study

    This is a prospective, open label, non-therapeutic, diagnostic imaging study. The purpose of this study is to utilize Pittsburgh Compound B positron emission imaging (PiB PET) to ascertain the relationship between change in amyloid burden over time, and concurrent change in clinical status.

  2. Bridging Study of C11 PiB and F18 Flutemetamol Brain PET

    Bridging Study of C11 PiB and F18 Flutemetamol Brain PET

    • Study type:

      Interventional What is this?

      Describes the nature of a clinical study. Types include:

      • Observational study — observes people and measures outcomes without affecting results.
      • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
      • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

    About this study

    The intent of this research protocol is to test the equivalency of two amyloid imaging drugs (C11 Pittsburgh Compound B and F18 Flutemetamol). The investigators hypothesize that there will be no significant difference in the distribution of the agents to areas of amyloid deposition in the brain or to other normal brain structures. Recent data have shown similarity in the distribution of the drugs in subjects with AD or mild cognitive impairment (MCI). No comparison data of the two PET drugs in normal subjects has been published. It is important to understand differences in the images and biodistribution from the two drugs in normal subjects as nonspecific accumulation of the drugs in brain structures such as white matter appear to differ slightly and could affect image performance.

    The current clinical functional imaging standard for patients with indeterminate cognitive impairment is FDG PET. To allow a comparison of the PET amyloid imaging compounds with FDG PET, FDG PET scans will also be important to acquire in the subjects for comparison.

  5. Exercise in Asymptomatic Pre-Alzheimer's Disease Pilot Study

    Exercise in Asymptomatic Pre-Alzheimer's Disease Pilot Study

    • Study type:

      Interventional What is this?

      Describes the nature of a clinical study. Types include:

      • Observational study — observes people and measures outcomes without affecting results.
      • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
      • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

    About this study

    5.4 million Americans have Alzheimer's disease (AD) costing $185 billion annually, while 15 million caregivers look after these individuals. AD is the sixth leading cause of death, but the only one in the top 10 causes that cannot be prevented.

    This study may demonstrate exercise in an amount attainable by many will be preventative in asymptomatic individuals including those with brain Abeta deposition already that are at impending risk of the disease. Sperling and colleagues(1) coined the research term AD-pathophysiological process (abbreviated AD-P) for use in studies such as the intervention in this proposal.

    Our long term goal is to assess whether exercise may be preventative of AD at older ages (=73, mean=75), when more than 40% of cognitively normal persons have A beta deposits, the hallmark of AD pathogenesis, in their brains. In a NIH RO1 grant submission the investigators proposed to conduct a partially blinded controlled preventative trial in 150 cognitively normal individuals, randomized in a 2:1 ratio to 18 months of moderate aerobic exercise versus 18 months of toning and stretching. All persons would have baseline and 18 month brain Abeta PET studies. The study was designed to determine whether an exercise intervention in persons mean age 75 would lead to decreased brain Abeta accumulation, increased hippocampal volume, improved cognition, and improved dementia-related biomarkers compared to the control group. The study would be unique in that the investigators would be able to examine if aerobic exercise slows the accumulation of brain Abeta in an older population, at which time Abeta deposition is common. If successful, this would provide an additional motivating reason to recommend exercise for most elderly persons.

    DaTSCAN Imaging in Aging and Neurodegenerative Disease

    • Study type:

      Interventional What is this?

      Describes the nature of a clinical study. Types include:

      • Observational study — observes people and measures outcomes without affecting results.

    About this study

    The investigators propose using DaTscan in patients with mild cognitive impairment (MCI), Parkinson's disease (PD), dementia with Lewy bodies (DLB), Alzheimer's disease (AD), and other neurodegenerative syndromes and disorders, to test several hypotheses - some confirmatory, and some novel. Such use will provide new data on the potential clinical and research utility of DaTscan in neurodegenerative diseases. The findings on DaTscan will be correlated with clinical diagnoses and other multimodal imaging studies (e.g., MRI, MRS, FDG-PET, and amyloid-PET) to enhance our understanding of neurodegenerative diseases.

    About this study

    This study consists of two parts, Part I and Part II. The purpose of Part I of the study is to assess the efficacy and safety of MK-8931 compared with placebo administered for 78 weeks in the treatment of Alzheimer's Disease (AD). The primary study hypotheses for Part I are that at least one MK-8931 dose is superior to placebo at 78 weeks of treatment with respect to change from Baseline in Alzheimer's Disease Assessment Scale Cognitive Subscale (ADAS-Cog) score and that at least one MK-8931 dose is superior to placebo at 78 weeks of treatment with respect to change from Baseline in Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory (ADCS-ADL) score. The first approximately 400 participants entering Part I of the study are identified as the Safety Cohort. Participants who complete Part I of the study may choose to participate in Part II, which is a long term double-blind extension to assess efficacy and safety of MK-8931 administered for up to an additional 260 weeks.

The Mayo Clinic Alzheimer's Disease Research Center needs people to participate in research studies, including people with mild cognitive impairment, early dementia, Alzheimer's disease and Lewy body dementia. The Alzheimer's Disease Research Center also needs clinical trial participants who haven't been diagnosed with a memory disorder.
