Voyager Therapeutics announced that the joint steering committee with its collaborator Neurocrine Biosciences has selected a lead development candidate in the Friedreich’s ataxia (FA) program. The candidate combines a frataxin (FXN) gene replacement payload with an intravenously administered, blood-brain barrier penetrant, novel capsid derived from Voyager’s TRACER™ capsid discovery platform. The companies expect the program to advance into first-in-human clinical trials in 2025.

Most individuals with Friedreich ataxia (FRDA) have homozygous GAA triplet repeat expansions in the FXN gene, correlating with a typical phenotype of ataxia and cardiomyopathy. A minority are compound heterozygotes carrying a GAA expansion on one allele and a mutation on the other. The study aim was to examine phenotypic variation among compound heterozygotes. Data on FXN mutations were obtained from the Friedreich Ataxia Clinical Outcome Measures Study (FA-COMS). The authors compared clinical features in a single-site FA-COMS cohort of 51 compound heterozygous and ..read more

The authors have previously demonstrated that single infusion of wild-type hematopoietic stem and progenitor cells (HSPCs) resulted in prevention of neurologic and cardiac complications of FRDA in YG8R mice, and rescue was mediated by FXN transfer from tissue engrafted, HSPC-derived microglia/macrophages to diseased neurons/myocytes. For a future clinical translation, an autologous stem cell transplantation approach was developed ..read more

The authors examined the clinical features of Friedreich ataxia (FRDA) patients who present first with cardiac disease in order to understand the earliest features of the diagnostic journey in FRDA. They identified a group of subjects in the FACOMS natural history study whose first identified clinical feature was cardiac. Only 0.5% of the total cohort belonged to this group, which was younger on average at the time of presentation. Their cardiac symptoms ranged from asymptomatic features to heart failure with severe systoli ..read more

This study examines high-resolution nerve ultrasound in FRDA patients, seeking correlations with established clinical markers of disease severity. Ten patients with Friedreich's Ataxia underwent a comprehensive clinical assessment with established scales (SARA, FARS, mFARS, INCAT, ADL 0-36, IADL). Additionally, they underwent nerve conduction studies and high-resolution nerve ultrasound. Quantitative evaluation of nerve cross-sectional area, conducted at 24 nerve sites usin ..read more

This paper aims to provide a neurologist's perspective on approaching patients with hereditary hyperkinetic disorders with a focus on select forms of dystonia, paroxysmal dyskinesia, chorea, and ataxia. Age at onset, initial symptoms, and their severity, as well as the presence of any concurrent neurological and non-neurological features, contribute to the individual clinical profiles of hereditary non-parkinsonian movement disorders, aiding in the selection of appropriate genetic testing strategies. There are also more specific diagnostic clues that may facilitate the d ..read more

Larimar Therapeutics, Inc. announced positive top-line data and successful completion of its four-week, placebo-controlled Phase 2 dose exploration study of nomlabofusp (CTI-1601) in participants with Friedreich’s ataxia. Nomlabofusp was generally well tolerated and demonstrated dose dependent increases in frataxin levels in all evaluated tissues (skin and buccal cells) after daily dosing of 14 days followed by every other day dosing until day 28 in the 25 mg and 50 mg cohorts.

Heart, dentate nucleus, and dorsal root ganglia (DRG) are targets of tissue damage in Friedreich ataxia (FA). This report summarizes the histology and histopathology of iron in the main tissues affected by FA. None of the affected anatomical sites reveals an elevation of total iron levels. In the myocardium, a small percentage of fibers shows iron-reactive granular inclusions. The accumulation of larger iron aggregates and fiber invasion cause necrosis and damage to the contractile apparatus. In the dentate nucleus, the principal FA-caused tissue injury is neuronal atrophy and grumose reaction ..read more

Alzheimer's disease (AD) is a complex, multifactorial neurodegenerative disease. However, the pathogenesis remains unclear. Recently, an increasing number of studies have demonstrated that ferroptosis is a new type of iron-dependent programmed cell death, contributes to the death of nerve cells in AD. By controlling iron homeostasis and mitochondrial function, the particular protein called frataxin (FXN), which is situated in the mitochondrial matrix, is a critical regulator of ferroptosis disease.. Here, the authors identified a novel underlying mechanism through which ferroptosis mediated by ..read more

Omavaloxolone, an NRF2 activator, recently became the first drug approved specifically for the treatment of Friedreich ataxia (FRDA). This landmark achievement provides a background for a review of the detailed data leading to the approval. The authors review the data from the 4 major articles on FRDA in the context of the authors' considerable (>1000 patients) experience in treating individuals with FRDA. The data is presented in the context not only of its scientific meaning but also in the practical context of therapy in FRDA. Omaveloxolone provides a significant advance in the treatment ..read more
