Leading the worldwide fight to treat and cure
Tay-Sachs, Canavan, GM1 and Sandhoff diseases

Clinical Trials (Current)

The Center for Information and Study on Clinical Research Participation (CISCRP) defines a clinical trial as, "a research study in human volunteers to answer specific health questions. Carefully conducted clinical trials are the fastest and safest way to find treatments that work in people and ways to improve health. Interventional trials determine whether experimental treatments or new ways of using known therapies are safe and effective under controlled environments. Observational trials address health issues in large groups of people or populations in natural settings." 

The decision to participate in a clinical trial is a personal and private decision. NTSAD supports families in all their care choices. Our role is to provide families with the tools and resources to make informed decisions that they can live with and that are right for their family.

Canavan Disease: Natural History Studies 

ONGOING - Natural History Study of Patients With Canavan Disease, CANinform (sponsored by Aspa Therapeutics)
CANInform, the Canavan disease natural history study, will be the first multinational effort to rigorously gather both retrospective and prospective data from this patient population. Data collection will include extraction of retrospective data from medical records of living patients and deceased patients, and collection of prospective, longitudinal data from living patients and their parent(s)/caregiver(s). Motor function assessments will be performed in the home by qualified study team members. In addition, families will be invited to attend clinic visits or will be followed by the clinical site remotely for up to 3 years.

Nervous System Degeneration of Glycosphingolipid Storage Disorders

The study will evaluate children with glycosphingolipid (GSL) storage disorders to investigate brain changes that cause nervous system degeneration. Patients of any age with Tay-Sachs, Sandhoff, GM1 Gangliosidosis or type 2 Gaucher may be eligible.

Inclusion criteria: Individuals greater than 6 months of age with GM1 or GM2 gangliosidosis documented by enzyme deficiency and/or mutation analysis in a CLIA-approved laboratory
