Spinocerebellar Ataxias: Understanding

Spinocerebellar Ataxias: Overview

Spinocerebellar ataxia (SCA) is a rare, progressive, inherited neurodegenerative disorder that primarily affects the cerebellum but can involve other parts of the central nervous system. It is classified into over 40 subtypes based on genetic loci, with common types including SCA1, SCA2, SCA3, and SCA6, which account for the majority of cases. SCA is characterized by the loss of voluntary muscle coordination, impacting gait, speech, and eye movement. Although primarily associated with the cerebellum and spinal cord, SCA can also affect other areas such as the basal ganglia, cortex, and peripheral nerves, making it a complex and diverse condition both genetically and clinically. Symptoms typically worsen over time, leading to significant disability. The age of onset and severity can vary widely, even within the same family, making diagnosis and management challenging.

The pathophysiology of spinocerebellar ataxia (SCA) is complex and not fully understood, but it involves a combination of genetic mutations, abnormal protein aggregation, mitochondrial dysfunction, and dysregulated cellular processes. Most SCAs are caused by genetic mutations, particularly CAG repeat expansions, which lead to the production of misfolded proteins called ataxins. These proteins aggregate in Purkinje cells, disrupting their normal function and ultimately causing neurodegeneration. The disease primarily affects the cerebellum and Purkinje cells, which are critical for motor coordination, leading to the hallmark symptoms of ataxia. Additional factors such as impaired autophagy, altered transcriptional regulation, channelopathies, and mitochondrial dysfunction further contribute to the disease progression. The degeneration of these cells results in a range of neurological impairments, with varying degrees of involvement in other parts of the central nervous system, including the spinal cord, brainstem, and basal ganglia.

The diagnosis of spinocerebellar ataxia (SCA) involves a combination of family history, neurological assessments, and genetic testing. A family history of similar symptoms in multiple relatives, along with the age of onset and progression of symptoms, can offer crucial clues. Neurological tests, including CT scans, MRIs, and electrophysiologic evaluations, help identify brain abnormalities and assess nerve function. Genetic testing is key for confirming specific mutations associated with SCA, and it can also identify at-risk individuals, aiding in family planning. While some SCA subtypes show distinct brain structure abnormalities, not all types are linked to a particular mutation, making the diagnosis complex.

The treatment and management of spinocerebellar ataxia (SCA) focus primarily on alleviating symptoms as there is no definitive cure. Symptomatic treatments include medications such as antiepileptics for seizures, beta-blockers for tremors, and antidepressants for mood disorders. In addition to pharmacological treatments, therapies like physical, occupational, and speech therapy play an essential role in improving motor function, balance, and daily living skills. Advances in research are exploring potential treatments targeting the misfolded mutant proteins, including the use of chemical chaperones, autophagy regulation, and RNA-based therapies. While these approaches show promise, neurorehabilitation remains a cornerstone of improving patients' quality of life and maintaining their independence.

Spinocerebellar Ataxias Emerging Drugs Chapters

This segment of the Spinocerebellar Ataxias report encloses its detailed analysis of various drugs in different stages of clinical development, including Phase III, II, I, Preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Spinocerebellar Ataxias Emerging Drugs

• Troriluzole: Biohaven Pharmaceuticals, Inc.

Troriluzole is a New Chemical Entity (NCE) and third-generation novel prodrug that modulates glutamate, the most abundant excitatory neurotransmitter in the human body. The primary mode of action of troriluzole is reducing synaptic levels of glutamate. Troriluzole increases glutamate uptake from the synapse, by augmenting the expression and function of excitatory amino acid transporters located on glial cells that play a key role in clearing glutamate from the synapse. Troriluzole has the potential to be developed in a number of other diseases associated with excessive glutamate. In February 2025, Biohaven Ltd. announced that the US Food and Drug Administration (FDA) has accepted for review the Company's New Drug Application for troriluzole for the treatment of adult patients with spinocerebellar ataxia. In November 2025, Biohaven Ltd. announced that it had received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) for the New Drug Application (NDA) seeking approval of VYGLXIA (troriluzole) for the treatment of spinocerebellar ataxia (SCA).

• Stemchymal: Steminent US, Inc.

Stemchymal is an allogeneic stem cell therapy, meaning it uses stem cells obtained from one patient to treat another. The mesenchymal stem cells (MSCs) used to create Stemchymal are isolated from the adipose, or fatty, tissue of healthy individuals. Once isolated from this primary tissue using a unique cell processing system, the MSCs are administered to recipients by intravenous (IV) infusion. As MSCs display low immunogenicity, they are less likely to cause an immune reaction in patients receiving treatment. These cells have also displayed therapeutic effects in vivo, with infusion shown to partially restore motor function in SCA mouse models. Stemchymal has also been granted orphan drug designation in Japan. Currently, the drug is in Phase II stage of its development for the treatment of Spinocerebellar Ataxias.

• VO659: Vico Therapeutics B. V.

VO659 is the first clinical candidate directly targeting the CAG repeat expansion, the mutation that causes all polyglutamine diseases. VO659 is an ASO that directly targets the CAG repeat expansion and reduces mutant protein in an allele preferential manner. VO659 is designed to bind directly to the CAG repeats, sterically block translation and reduce the mutant protein. The CAG repeat expansion causes nine polyQ diseases, including Huntington’s disease and various forms of spinocerebellar ataxia. By focusing on this common mutation, VO659 has the potential to address multiple polyQ disorders with a single therapy. VO659 employs an innovative allele-preferential approach. This precision targeting allows us to reduce the mutant protein while preserving essential normal gene function - a crucial advancement in treating these complex disorders like SCA. Currently, the drug is in Phase I/II stage of its development for the treatment of Spinocerebellar Ataxias.
