Measurement of Motor Function in Children With Canavan Disease: Concordance Between Remote and In-Person Assessments.

Pediatric neurology2026 Feb 18

The increasing use of decentralized and hybrid clinical trials generates a critical need for validation of remote virtual assessments in pediatric rare diseases. This study evaluates the concordance between standardized motor assessments obtained remotely and in-person over 2 years in children with Canavan disease. Thirteen participants completed paired remote/in-person motor assessment visits with one of 5 trained physical therapist raters. Paired Hammersmith Infant Neurological Exam Section 2 (HINE-2) Motor Milestones and Gross Motor Function Measure (GMFM-88) scores were compared using Lin's Concordance correlation coefficients (CCCs) and Bland-Altman plots. HINE-2 total scores from 85 remote/ in-person visit pairs were highly correlated (Lin's CCC = 0.98; P < 0.001) with low systematic assessment method bias and high precision. GMFM-88 remote/ in-person total raw scores were also highly correlated (Lin's CCC = 0.98; P < 0.001) with low systematic assessment method bias and modest difference score variability. Estimated mean paired differences between remote and in-person total scores was 0.01 for HINE-2 and 0.54 for GMFM-88. Findings from this study support the utility and validity of two remote motor clinical outcome assessments in children with Canavan disease and highlight the potential value of combining a motor milestone assessment (HINE-2) with a granular evaluation of motor function (GMFM-88) for a more comprehensive evaluation in medically high-risk children.

Human iPSC-derived neural progenitor cells rescue motor function and brain pathology in symptomatic Canavan disease mice.

Stem cell reports2026 Feb 10

Canavan disease (CD) is a severe neurodegenerative disorder caused by aspartoacylase (ASPA) deficiency, leading to N-acetyl-L-aspartic acid (NAA) accumulation and spongy degeneration. While several therapeutic candidates improve outcomes in CD mouse models when delivered before symptom onset, there remains a need for treatments targeting established disease pathology. Here, we demonstrate that transplantation with human induced pluripotent stem cell (iPSC)-derived neural progenitor cells (NPCs) expressing a functional ASPA gene (ASPA iNPCs) can rescue disease manifestations in symptomatic CD (Nur7) mice. When administered at postnatal day 21 (P21), ASPA iNPCs successfully engrafted, differentiated into neural lineage cells, and restored ASPA activity as revealed by reduced NAA level. Transplanted mice showed a significant reduction in brain and cerebrospinal fluid (CSF) NAA levels, decreased vacuolation across multiple brain regions, improved myelination, and enhanced motor function 6-month post-transplantation. Our findings demonstrate that ASPA iNPC transplantation can effectively reverse established CD pathology, suggesting therapeutic potential for treating symptomatic patients.

Discovery of N-Acetyltransferase 8-Like (NAT8L) inhibitors based on a N-Acylated (Piperidin-3-ylmethyl)-1,2,4-Oxadiazole Scaffold.

ACS medicinal chemistry letters2026 Feb 03

Canavan disease (CD) is an autosomal recessive genetic disorder caused by mutations in the ASPA gene, which encodes the enzyme aspartoacylase. These mutations lead to a deficient enzymatic activity and increased concentrations of its substrate, N-acetylaspartate (NAA), in the brain and other tissues. Aspartate N-acetyltransferase, encoded by the N-acetyltransferase 8-like (NAT8L) gene, catalyzes the biosynthesis of NAA from aspartate and acetyl-CoA. Therefore, inhibition of NAT8L has been implicated as a promising therapeutic strategy for CD by normalizing NAA levels in the brain. Our high throughput screening campaign followed by a rigorous hit validation process identified 2-(2-fluorophenoxy)-1-(3-((3-(thiophen-3-yl)-1,2,4-oxadiazol-5-yl)methyl)piperidin-1-yl)ethan-1-one (4a) as a low micromolar, noncarboxylic acid inhibitor of NAT8L. Subsequent structural optimization led to the discovery of two submicromolar NAT8L inhibitors. Although these inhibitors displayed high clearance in liver microsomes, the new scaffold, devoid of a carboxylic acid moiety, could potentially lead to potent and brain-penetrant NAT8L inhibitors through further molecular refinement.

Deep Intronic SVA_E Insertion Identified as the Most Common Pathogenic Variant Associated With Canavan Disease: A Diagnostic Blind Spot.

Neurology. Genetics2025 Oct

Canavan disease (CD) is a neurodegenerative disorder in which biallelic pathogenic variants in ASPA result in spongiform degeneration of the cerebral white matter, leading to progressive and irreversible motor and cognitive decline. Despite comprehensive genetic testing, many individuals with clinical and biochemical diagnoses of CD remain without a definitive molecular diagnosis. This gap hinders access to emerging gene-targeted therapies and limits participation in clinical trials. Our objective was to understand the genetic etiology of 8 unsolved cases of CD. We used long-read sequencing (LRS) to investigate 8 individuals clinically and biochemically diagnosed with CD but who had negative genetic testing results. We performed targeted LRS using the Oxford Nanopore Technologies platform for 3 unrelated individuals and PacBio HiFi for an additional individual from our cohort. We performed targeted LRS on barcoded and pooled samples from the remaining affected individuals. To investigate functional impact on gene function, we performed RNA sequencing (RNA-seq) with and without cycloheximide on fibroblasts. We then evaluated the allele frequency in the population using gnomAD. We identified an ∼2,600-bp SVA_E retrotransposon intronic insertion in ASPA in all 8 individuals. The insertion was found to be either homozygous or compound heterozygous trans with a known pathogenic variant in all individuals. RNA-seq indicated that the SVA_E insertion creates a novel splice acceptor site within intron 4 of ASPA that causes aberrant splicing and transcript degradation. Surprisingly, the frequency of this variant in population databases suggests that it is the most common pathogenic variant in ASPA and that it is present across ancestry groups. Our study identified the most common pathogenic variant in ASPA, which has been overlooked in 25 years of CD research. Considering this, it is important to ensure that all testing laboratories can detect this variant through diagnostic testing and carrier screening. Our study highlights a substantial blind spot in standard short-read diagnostic pipelines, which historically have missed or overlooked these types of insertions. It also shows the power of emerging technologies, such as LRS and RNA-seq, to identify new classes of variants for genetic disorders, including CD.

Oligodendrocyte-targeted adeno-associated virus gene therapy for Canavan disease in children: a phase 1/2 trial.

Nature medicine2025 Nov

This open-label phase 1/2 clinical study uses a novel recombinant vector, rAAV-Olig001, with selective tropism for oligodendrocytes, to deliver gene therapy for Canavan disease (CD), a rare leukodystrophy characterized by defective aspartoacylase and elevated N-acetyl-aspartic acid (NAA) concentrations. A total of 8 participants received intracranial doses of 3.7 × 1013 vector genomes (vg) of rAAV-Olig001-ASPA (MYR-101), with an interim analysis at 12 months. The primary objective was to assess the safety of intracranial dosing of MYR-101 in children with typical CD. Efficacy measures included Mullen Scales of Early Learning (MSEL), Gross Motor Function Measure (GMFM) and analysis of NAA, myelination, white matter and extracellular water content in the brain. The participants were White; 5 (62.5%) were male. Of the participants, 7 (87.5%) experienced ≥1 serious adverse event, none of which were considered MYR-101 related. All participants experienced ≥1 adverse event. All adverse events and serious adverse events resolved fully. Treatment reduced NAA concentrations in cerebrospinal fluid (P = 0.0008), increased myelination (P = 0.0137) and improved MSEL developmental outcomes (P = 0.0171). Thus, interim results suggest that gene therapy with MYR-101 is well tolerated and shows early effects in CD. While these findings are preliminary, reductions in NAA concentrations indicate ASPA expression and increases in myelination and imply successful targeting of oligodendrocytes. These results may support the development of similar gene therapy strategies for other demyelinating and metabolic brain disorders. ClinicalTrials.gov registration: NCT04833907 .
