Spinocerebellar Ataxias Understanding and Treatment Algorithm

Spinocerebellar Ataxia Overview, Country-Specific Treatment Guidelines, and Diagnosis

Spinocerebellar ataxia is an inherited, progressive, neurodegenerative, and heterogeneous disease that mainly affects the cerebellum. Spinocerebellar Ataxia is a subset of hereditary cerebellar ataxia and is a rare disease. Spinocerebellar ataxia does not compulsorily mean that it is restricted to the cerebellum and spinal cord. It may involve the other parts of the central nervous system as well, such as pontine nuclei, spinal cord, peripheral nerves, cortex, basal ganglia, etc. SCA6 is restricted to the cerebellum whereas SCA2 spares cerebellum. Well-defined and common types are SCA1, SCA2, SCA3, and SCA6, which accounts for more than half of cases and other rare variants constitute the remaining cases.

Spinocerebellar ataxia can result from inherited gene mutations, particularly those involving trinucleotide repeat expansions. While not all types of Spinocerebellar ataxias are linked to the same gene, most follow an autosomal dominant inheritance pattern, where inheriting one mutated gene from a parent is enough to cause the condition. This means that each child of an affected individual has a 50% chance of inheriting the mutation. However, there are also autosomal recessive forms where both parents must pass on an abnormal gene, typically without displaying symptoms themselves.

Spinocerebellar Ataxia Treatment

Spinocerebellar ataxia, a genetic condition lacking a definitive cure, is managed primarily through symptomatic treatment aimed at alleviating associated symptoms such as seizures, tremors, depression, ataxia, and eye issues. Treatment approaches include antiepileptic medications for seizures, botulinum toxin injections to address dystonia, beta-blockers and primidone for tremors, antidepressants to manage depression, and levodopa for Parkinsonism symptoms. Additionally, the use of N-acetyl cysteine has shown promise in neurological disorders and Spinocerebellar Ataxia, while citalopram has demonstrated benefits by reducing ataxin-3 levels and improving patient behavioral status.

Spinocerebellar Ataxia Epidemiology

The Spinocerebellar Ataxia epidemiology chapter in the report provides historical as well as forecasted in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain), the United Kingdom, and Japan from 2024 to 2034.

• VO659: VICO Therapeutics

VO659 is an allele-preferential antisense oligonucleotide product candidate being developed for patients with spinocerebellar ataxia types 3 and 1 (SCA3, SCA1) and is in Phase I/II clinical trial. These polyglutamine diseases are caused by a CAG repeat expansion that results in an elongated polyglutamine tract that makes the resulting mutant protein toxic to nerve cells. VO659 preferentially targets expanded CAG repeats in the mutant mRNA transcript and inhibits mRNA translation leading to reduction of mutant protein with the goal of stopping or reversing disease progression. In preclinical studies, significant reductions in mutant ATXN3 and ATXN1 protein levels were observed in SCA3 and SCA1 mouse models, respectively.
