Phase 1/2 Clinical Trial of LY3884963 in Patients With Frontotemporal Dementia With Progranulin Mutations (FTD-GRN)

Study J4B-MC-OKAA is a Phase 1/2, multi-center, open-label ascending dose, first-in-human study that will evaluate the safety and effect of intra-cisternal LY3884963 administration on progranulin protein (PGRN) levels in patients with frontotemporal dementia with progranulin mutations (FTD-GRN). Two escalating dose (low dose and medium dose) cohorts are planned, as well as one bridging cohort which will allocate patients to receive either low or medium dose. The duration of the study is 5 years. During the first year, patients will be evaluated for the effect of LY3884963 on safety, tolerability, immunogenicity, biomarkers, and efficacy. Patients will follow up for an additional 4 years to monitor safety and changes on selected biomarkers and clinical outcomes.

MSC-Exosome Therapy for Frontotemporal Dementia

This study is testing a new treatment for Frontotemporal Dementia (FTD) - a progressive brain disease that affects personality, behavior, and language. Currently, there is no cure for FTD and no approved medication that can slow down or stop the disease. Existing treatments only help manage some symptoms temporarily. The investigational treatment in this study is made from exosomes - tiny particles naturally released by umbilical cord stem cells. Exosomes act like "message carriers" between cells. Researchers believe they may help protect brain cells, reduce harmful protein buildup, and improve brain function. The exosomes will be given as a nasal spray (sprayed into the nose). This method may allow the treatment to reach the brain directly without needing to pass through the blood-brain barrier (a natural protective layer that often blocks medications from entering the brain).

Neurologic Stem Cell Treatment Study

This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/

A Study of Caregiver Connections Via Technology in Dementia

This research is being done to develop a unique matching process for caregivers of persons living with dementia, such as Alzheimer's disease, Lewy body dementia, frontotemporal degeneration, or other dementia syndromes. Dementia caregivers often assume greater caregiving burden than do non-dementia caregivers, and the caregiving duration tends to be longer. Many caregivers do not have the adequate support they need. Peer-to-peer support has been shown to improve quality of life, more engagement with services, improve caregiver health, and reduce hospitalizations in the person they are caring for. This study will help determine whether caregivers of persons with dementia would find a technology-based caregiver matching program valuable for the purpose of emotional support.

Tanycytes in Alzheimer's Disease and Frontotemporal Dementia

Metabolic and hormonal deregulations are both a risk factor and a hallmark of Alzheimer's disease (AD) and frontotemporal dementia (FTD), occurring early in the course of the disease. In FTD in particular, hyperorality and dietary changes are associated with metabolic and hormonal changes such as altered levels of the anorexigenic hormone leptin. The hypothalamus is a brain region that controls metabolism and hormonal systems. Hypothalamic function depends on its ability to sense peripheral signals. The hypothalamus sits on a circumventricular organ called the median eminence (ME) that puts it in contact with systemic blood circulation. In the ME, fenestrated capillaries allow the diffusion of bloodborne factors. However, despite the lack of blood-brain barrier at brain microvessels, diffusion is controlled by specialized ependymoglial cells, the tanycytes, which exert a barrier function between the ME and the third ventricle and controls the access of blood-borne molecules into the hypothalamus. Previous work from our laboratory and the ERC consortium has highlighted the role of tanycytes not only in the regulation of the release of neurohormones from neuroendocrine nerve terminals into the pituitary portal blood circulation, but also in the transport of circulating leptin into the hypothalamus. Hence hypothalamic dysfunction in AD and FTD can result either from dysregulation of neuroendocrine secretions, direct neuronal loss or from defective transport (and hence resistance) to hormones like leptin. This study is to demonstrate that leptin transport though tanycytes is early altered in FTD and AD and correlates

A Study of PBFT02 in Participants With FTD and Mutations in the Granulin Precursor (GRN) or C9ORF72 Genes

Retinal Hyperspectral Imaging in Neurodegenerative Diseases

Hyperspectral retinal imaging is a non-invasive imaging modality in which a series of images of the retina are captured using light of different wavelengths. The resulting "hypercube" of data provides a wealth of information about the retinal structure. Our group has developed evidence supporting a role for this technology in the detection of retinal amyloid beta in Alzheimer's disease. We are undertaking further studies to establish the role of this method in the assessment of people with dementia, or those at risk of Alzheimer's disease. In addition, we wish to test whether the approach may have value in other forms of dementia or neurodegenerative disease such as Parkinson's disease, Lewy-Body dementia or vascular dementia.

A Study to Evaluate the Safety and Effect of AVB-101, a Gene Therapy Product, in Subjects With a Genetic Sub-type of Frontotemporal Dementia (FTD-GRN)

The goal of this clinical study is to learn about an investigational gene therapy product called AVB-101, which is designed to treat a disease called Frontotemporal Dementia with Progranulin Mutations (FTD-GRN). FTD-GRN is an early-onset form of dementia, a progressive brain disorder that affects behavior, language and movement. These symptoms result from below normal levels of a protein called progranulin (PGRN) in the brain, which leads to the death of nerve cells (neurons), affecting the brain's ability to function. The main questions that the study aims to answer are: 1. Is a one-time treatment with AVB-101 safe for patients with FTD-GRN? 2. Does a one-time treatment with AVB-101 restore PGRN levels to at least normal levels? 3. Could AVB-101 work as a treatment to slow down or stop progression of FTD-GRN? In this study there is no placebo (a dummy pill or treatment used for comparison purposes), so all participants will receive a one-time treatment of AVB-101 delivered directly to the brain, with follow-up assessments for 5 years.

Vortioxetine for the Treatment of Mood and Cognitive Symptoms in Frontotemporal Dementia

The goal of this clinical trial is to learn if vortioxetine improves mood symptoms and cognition in patients with early-stage behavioral variant Frontotemporal Dementia (bvFTD). The main questions this study aims to answer are: 1. Do individuals with mood symptoms and bvFTD have brain changes and cognitive profiles that differ compared to individuals without bvFTD? 2. Do mood symptoms and cognition improve following treatment with vortioxetine? Researchers will also determine whether there are changes in the brain associated with vortioxetine treatment. Participants will: * Undergo a screening visit that involves clinical assessments and laboratory tests * Undergo an initial brain magnetic resonance imaging (MRI) and fluorodeoxyglucose (18F) Positron Emission Tomography (FDG PET) scan before starting treatment with vortioxetine * Undergo memory and problem-solving tests before starting treatment with vortioxetine * Undergo approximately 12 weeks of treatment with vortioxetine, during which time there will be regular contact and assessments with the study psychiatrist * Undergo a repeat PET scan and repeat memory and problem-solving tests after 12 weeks of treatment with vortioxetine
