Pharmacokinetics, Safety and Tolerability of Zavesca (Miglustat) in Patients With Infantile Onset Gangliosidosis: Single and Steady State Oral Doses
United States10 participantsStarted 2004-07
Plain-language summary
We want to see if Zavesca (or miglustat) is safe and can be tolerated by patients with acute infantile onset GM2 gangliosidosis - classical Tay-Sachs and infantile onset Sandhoff disease. We know that miglustat inhibits the formation of GM2 ganglioside, the compound that is stored in the brains of children with Tay-Sachs and Sandhoff disease. Since it inhibits the synthesis of ganglioside, miglustat may be able to reduce or delay the onset of clinical symptoms.

What they're measuring
1
Biomarkers (level of GM2 ganglioside, chitotriosidase activity, anti-GM2 antibodies) in plasma, serum and CSF will be measured at initial visit (run-in period), Week 13, and Week 25.
. Patients who have a history of significant gastrointestinal disorders, including clinically significant diarrhea (\>3 liquid stools per day for \> 7 days), without definable cause within 3 months of baseline visit.
✕. Patients with a high probability of dying during the 6-month assessment period of the study.
✕. Patients who in the opinion of the investigator (for whatever reason) are thought to be unsuitable for the study.
