AAV9 Gene Therapy in Type II GM1 Gangliosidosis - A Phase 1-2 Trial.

The New England journal of medicine2026 Feb 06

GM1 gangliosidosis, caused by biallelic variants in GLB1, results from deficiency of lysosomal β-galactosidase, which degrades GM1 ganglioside. This fatal neurodegenerative disease currently has no effective therapy. In a phase 1-2, open-label, dose-escalation study, we assessed immunosuppression and a single intravenous infusion of adeno-associated virus serotype 9 (AAV9) encoding β-galactosidase in children with type II GM1 gangliosidosis with late-infantile or juvenile onset. The primary end point was safety. Secondary end points included changes from baseline in the cerebrospinal fluid (CSF) GM1 ganglioside concentration and β-galactosidase activity, clinical assessments (including the Clinical Global Impression-Improvement [CGI-I] score, assessed on a scale from 1 [very much improved] to 7 [very much worse]), and neuroimaging patterns. Nine participants were enrolled. Over a 3-year period, 124 adverse events occurred, 30 of which (8 gastrointestinal events, 21 laboratory abnormalities associated with inflammation, and 1 tachycardia event) were deemed by the investigator as being possibly, probably, or definitely related to the gene therapy. Five serious adverse events occurred, including vomiting that led to hospitalization in one participant, which was attributed to the gene therapy. Serum aspartate and alanine aminotransferase levels increased in all participants and returned to baseline levels by 18 months. In all participants, the CSF β-galactosidase level increased and CSF GM1 ganglioside level decreased. Expressive communication and gross motor scores appeared stable, but fine motor and receptive communication scores decreased. The median CGI-I score was 3 (indicating minimal improvement) at 2 years and 4 (indicating no change) at 3 years; in historical controls, scores have been shown to increase (indicating worsening) over time. Neuroimaging showed patterns consistent with reduced rates of cerebral atrophy and favorable changes in myelination as compared with baseline. In this study involving nine participants with type II GM1 gangliosidosis, a single infusion of AAV9 encoding β-galactosidase was associated with adverse events, including severe vomiting in one participant and elevated liver-enzyme levels in all participants. Secondary end-point results suggested improvements in biochemical markers and neuroimaging patterns and stable or reduced rates of developmental deterioration in some measures.

From Molecule to Meaning: Neuronopathic Biomarkers and Clinical Relevance in GM1.

Journal of inherited metabolic disease2026 Jan

GM1 gangliosidosis is a rare, progressively neurodegenerative lysosomal storage disorder characterized by profound central nervous system involvement and substantial clinical heterogeneity. The development of reliable biomarkers is essential for tracking disease progression, stratifying patients, and advancing clinical trial readiness. Primary substrate markers, including cerebrospinal fluid (CSF) GM1 ganglioside and related lysosphingolipids, provide direct biochemical indices of lysosomal dysfunction. Emerging glycan signatures may further reflect disruptions in glycosylation pathways and responses to therapeutic intervention. Neurofilament light chain (NfL), a sensitive indicator of axonal injury, is consistently elevated in GM1 and shows promise as a fluid biomarker, although it does not convey regional specificity. Neuroimaging offers complementary insight into the structural and metabolic consequences of disease. Characteristic findings include diffuse white matter abnormalities, thalamic and basal ganglia signal changes, cortical and cerebellar atrophy, and ventriculomegaly. Quantitative MRI and magnetic resonance spectroscopy (MRS) reveal longitudinal declines in tissue volume and neuronal integrity that parallel functional deterioration. Diffusion-based methods, including differential tractography, highlight progressive loss of white matter microstructure relative to age-matched controls. However, severe anatomical distortion in GM1 limits the applicability of standard neuroimaging atlases, necessitating manual or semi-automated segmentation approaches. Together, fluid biomarkers (gangliosides, lysosphingolipids, glycans, NfL) and advanced neuroimaging metrics (volumetry, MRS, diffusion imaging) establish a multimodal framework for evaluating disease burden and therapeutic response. Standardized methodologies, harmonized natural history datasets, and genotype-stratified analyses will be critical for validating these biomarkers across GM1 subtypes. Strengthening this biomarker ecosystem will enable sensitive and clinically meaningful endpoints to support future therapeutic development in GM1 gangliosidosis.

Lentiviral hematopoietic stem cell gene therapy ameliorates GM1-gangliosidosis in mice.

Molecular therapy : the journal of the American Society of Gene Therapy2026 Mar 04

Lysosomal storage diseases (LSDs) are >70 devasting diseases causing progressive neurodegeneration and systemic symptoms. Hematopoietic stem cell (HSC) gene therapy (GT), i.e., the autologous transplantation of genetically corrected HSCs by lentiviral transduction, has shown transformative efficacy in multiple neurodegenerative LSDs so far. We developed a translational HSC GT approach for GM1-gangliosidosis, a neurodegenerative LSD due to β-galactosidase (β-gal) deficiency, based on a lentiviral vector expressing either the human or the murine therapeutic enzyme. Cells were administered by a standard intravenous injection, or by an innovative, combined systemic and local cell delivery to enhance the GT efficacy. In the murine model of the disease, GT broadly restored enzymatic activity and reduced the lysosomal storage in the brain, ameliorated the neuromuscular phenotype, and increased animal survival. Combined cell-delivery GT with the human enzyme, or standard intravenous GT with the murine β-gal were similarly effective in mitigating disease phenotype, indicating a substantial therapeutic potential of the approach for a future clinical translation.

Alkaline Phosphatase and Infantile GM1 Gangliosidosis: A Simple Biomarker for a Complex Disease?

JIMD reports2026 Mar

GM1 gangliosidosis is a lysosomal storage disease (LSD) caused by β-galactosidase deficiency, characterized by the accumulation of gangliosides in various tissues. Among different GM1 forms (infantile form, late-infantile and juvenile form, and late-onset form), the infantile form is the most severe: despite an early clinical onset with rapid neurodegeneration, coarse face, abdominal visceromegaly and skeletal abnormalities, the diagnosis is usually delayed, given the lack of recognized early disease-specific markers. We report the case of a newborn presenting with mild edema of hands and feet, mild transient hypoalbuminemia and isolated hyperphosphatasemia at three weeks of life. The first cardiological evaluation showed mild mitral regurgitation. Despite the absence of neurological symptoms, organomegaly, or a coarse face, the turgid consistency of the limbs, together with mitral regurgitation and persistent hyperphosphatasemia, led to multiorgan investigations with discovery of bilateral cherry-red spots and a beak-shaped lumbar vertebra. The cardiological follow-up revealed a dysplastic mitral valve. In the suspicion of a lysosomal disease, biochemical investigations were planned. An altered profile of urinary oligosaccharides, along with low β-galactosidase activity in leukocytes, led to the diagnosis of infantile GM1 gangliosidosis at 3 months of age. The GLB1 gene analysis confirmed the diagnosis. Genetic testing for GLB1 should be considered in cases of persistent hyperphosphatemia, especially if it is associated with any other clinical indicator of GM1, such as limb edema.

Novel Galactosidase-Beta-1 Variant in Infantile GM1 Gangliosidosis: A Case Report.

Cureus2026 Jan

GM1 gangliosidosis is an autosomal recessive lysosomal storage disorder caused by pathogenic GLB1 variants that impair β-galactosidase activity, resulting in GM1 ganglioside accumulation. The infantile (type I) form is the most severe. We describe the case of a one-year-old girl born to consanguineous parents who presented with developmental regression, hypotonia, coarse facial features, hepatosplenomegaly, macular cherry-red spots, Mongolian spots, and sensorineural hearing loss. Whole-exome sequencing revealed a novel homozygous GLB1 variant, NM_000404.4:c.1525T>A (p.Trp509Arg), absent from population databases and predicted deleterious by in silico tools. According to the American College of Medical Genetics and Genomics guidelines, it is classified as a variant of uncertain significance, though the phenotype-genotype match suggests pathogenicity. This case broadens the GLB1 mutational spectrum and underscores the value of early genetic testing for diagnosis, counseling, and management.
