GM1 Gangliosidosis clinical trials at University of California Health
2 in progress, 1 open to eligible people
open to eligible people ages 4 months to 36 months
PBGM01 is a gene therapy for GM1 gangliosidosis intended to deliver a functional copy of the GLB1 gene to the brain and peripheral tissues. This study will assess in a 2-stage design the safety, tolerability and efficacy of this treatment in patients with early onset infantile (Type 1) and late onset infantile (Type 2a) GM1 gangliosidosis. Results from the Type 1 and Type 2a groups will be assessed separately.

Owing to the rarity, severity, speed of progression and fatal prognosis of infantile and juvenile GM1, there is a limited understanding of overall disease progression and meaningful outcome measures. This study aims to build a natural history data set through collection of a number of clinical, imaging, and laboratory assessments that may be specific predictors of GM1 disease progression and clinical outcome. Having a GM1 natural history data set can inform potential efficacy endpoints and biomarkers for future clinical trials. This natural history study will follow up to 40 subjects diagnosed with GM1 gangliosidosis (up to 20 infantile (Type 1) and 20 late infantile/juvenile (Type 2)) for up to 3 years. Visits will be conducted every 6 months, during which several procedures will be performed and the data recorded in order to learn about the natural course of the disease, including changes in clinical and neurological assessments and electrophysiologic, imaging and biofluid biomarkers. Study procedures include: physical & neurological exam, blood & urine sample collection, questionnaires & assessments of development, seizure diary, ECHO, ECG, x-ray and ultrasound (if MRI not performed), EEG and genetic testing (if not already done). The following procedures are subject to local/institutional policies and the medical discretion of the Study Physician: MRI, lumbar puncture (spinal tap) and General anesthesia/sedation (for MRI and LP).
