Tay-Sachs, Canavan and related diseases

Clinical Trials

There are many definitions of clinical trials but generally they are studies done in people to treat or better understand disease. The decision to participate in clinical trials 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.

Past Clinical Trials

Pyrimethamine for Late Onset Tay-Sachs

A small investigator-sponsored clinical trial of the molecular chaperone Pyrimethamine was done in adults with Late Onset Tay-Sachs. A protocol has been developed for the next phase of the trial to address proper dosage.  Efforts have stalled due to regulatory requirements and funding challenges.

Zavesca for all forms of Tay-Sachs, Sandhoff and GM-1

Clinical trials in babies, children and adults with Tay-Sachs and Sandhoff of the substrate inhibitor Zavesca® (miglustat) did not show therapeutic benefit. Zavesca is FDA approved for Gaucher, which provides families affected by other lysosomal diseases the option of using the drug for off-label use.

Zavesca may have a small therapeutic effect on children affected by Juvenile GM-1. Contact our director of family services, Kim Kubilus at This email address is being protected from spambots. You need JavaScript enabled to view it. or 800.906.8723 to learn more.
