Potential Treatment: CMT2S Caused By IGHMBP2 Cryptic Splice Site Variant With ASO Based Therapeutic

Monday, October 2nd at 12:30 pm US EDT.

VCA-894A is a novel antisense oligonucleotide (ASO) with a mechanism of action that specifically targets a cryptic splice site variant within immunoglobulin mu-binding protein 2 (IGHMBP2). Mutations within IGHMBP2 play a pivotal role in the manifestation of CMT2S, likely due to alpha-motor neuron loss, and consequently peripheral nervous system deterioration. ASOs have the capacity to modulate gene expression, allowing for the personalized treatment of rare diseases. CMT2S is a rare subtype of Charcot-Marie-Tooth disease (CMT), an inherited peripheral neuropathy for which there is no available treatment. The prevalence of CMT2S is estimated to be less than 1 in 1,000,000 worldwide. Onset of CMT2S begins in early childhood. CMT2S is characterized by slowly progressive distal muscle weakness and atrophy, affecting the upper and lower limbs in a child's first decade of life, leaving patients with decreased reflexes and sensory impairment.
