Summary: Background:In the U.S., about 53 million informal, unpaid caregivers provide care to a person who is ill, is disabled, or has age-related loss of function. These caregivers may be adult children, spouses, parents, or others. The stress of providing long-term care affects caregivers health and well-being. Researchers want to learn more about this stress and its effects.Objective:To learn how the ca...

Summary: This is a phase 1 open-label, single-administration of gene therapy agent AAV9/CLN7, administered intrathecally into the lumbar spinal cord region of pediatric patients with CLN7 Batten disease.This study consists of a one-time injection of AAV9/CLN7. There are two Cohorts with a low dose and a high dose.The primary objective for this clinical study is to evaluate safety. The secondary objective i...

Summary: This is a multicenter, international, study to assess the natural history data from people with Batten disease by collecting both retrospective and prospective information about the motor, behavioral and functional capabilities of patients. The study initially has 2 cohorts. Cohort 1 (n ≈ 75) includes subjects with CLN6 Batten disease. Cohort 2 (n ≈ 120) includes subjects with juvenile CLN3 Batten...

Summary: This is a multicenter, observational study for patients with a confirmed diagnosis of neuronal ceroid lipofuscinosis type 2 (CLN2 disease), also known as TPP1 deficiency, who intend to be or are currently being treated with cerliponase alfa. Patients receiving or expected to receive cerliponase alfa within 60 days of signing the informed consent form (ICF) may be eligible to enroll in the study, a...

Summary: Neuronal Ceroid Lipofuscinoses (NCL) or Batten's disease are the most common juvenile neurodegenerative disease, characterized by early blindness, movement disorders, cognitive and behavioral impairment, epilepsy, and retinopathy.This study aims to collect clinical and laboratory data of patients with NCL taking Trehalose.

Summary: The purpose of this study is to explain the provision of palliative care at the end of life by the implementation of the ELNEC course, as WBT Program using the Normalization Process Theory, that focus attention on how complex interventions become routinely embedded in practice. In addition to, identify the changes implemented by the participant nurses (intervention group) in their clinical practic...

Summary: This is an observational study that aims at assessing the natural history of NCL diseases as part of the international DEM-CHILD Database.1. Patient data are collected from medical records, patient questionnaires and routine follow up clinical examinations with focus on assessing progression in key areas of disease such as motor, language, cognition, seizures, vision, and behavior.2. A local biore...

Summary: This is a long-term safety and efficacy study in subjects with CLN6 Batten disease who previously received a single intrathecal administration of AT-GTX-501.

Summary: CLN5 and CLN7 are forms of Batten Disease, and neurodegenerative disorders in children causing psychomotor regression, seizures, blindness, loss of ambulation and premature death, and have no available treatments.The purpose of this study is to investigate the clinical characteristics and natural clinical progression of symptoms in individuals with CLN5 and CLN7. This natural history study is impo...

Summary: The investigators propose a study to assess cognitive and developmental outcomes of patients with CLN2 that are untreated and receiving cerliponase alfa. This study aims to validate standardized assessment measures to establish a standard of care. The secondary aim is to compare cognitive and developmental outcomes of patients with CLN2 that are receiving celiponase alfa to a natural history cohor...

Summary: Background:CLN3, or Batten disease, is a genetic disorder. This deadly disease leads to decline of brain and nervous system functions. Symptoms of CLN3 typically occur between 4 and 7 years of age. They include changes in how a person sees, thinks, and moves. CLN3 can also cause seizures. No effective treatments for the disease are yet known. There is limited testing of potential therapies. Resear...

Summary: CLN6 is a rare, neurodegenerative disease that causes progressive loss of acquired skills with motor delay, visual loss, seizures and ataxia. The investigators propose a natural history study of this rare disorder since it is currently unknown. It is important to understand disease progression in CLN6 disease to be able to judge therapeutic efficacy as emerging therapies like gene therapy become a...
