AUSTIN, Texas--(BUSINESS WIRE)--Feb 24, 2026--
IntraBio Inc. today announced that a positive opinion recommending Orphan Medicinal Product Designation for Acetylleucine for the treatment of CACNA1A disorders has been granted by the Committee for Orphan Medicinal Products (COMP) of the European Medicines Agency (EMA). The European Commission is expected to grant the designation in Q2 2026.
CACNA1A-related disorders are rare, genetic neurological conditions characterized by progressive impairment in coordination, balance, speech, and overall neurological function. Currently, no approved therapies exist for these patients.
Acetylleucine is a modified amino acid under development for a range of neurodegenerative and neurodevelopmental disorders. Building on its prior Phase III pivotal trials with levacetylleucine for Niemann-Pick disease type C (NPC) and for Ataxia-Telangiectasia, IntraBio is preparing to initiate a multinational Phase III trial evaluating levacetylleucine for CACNA1A-related disorders in 2026 (ClinicalTrials.gov: NCT07221292 ).
“We are moving with urgency to initiate our global Phase III clinical trial and to advance the investigation of levacetylleucine for as many rare disease communities as possible,” said Taylor Fields, Chief Development Officer at IntraBio. “We remain committed to rigorous label expansion in rare and complex neurological diseases with huge unmet medical need.”
Levacetylleucine is an investigational product for the treatment of CACNA1A-related disorders. Its safety and efficacy for this specific indication have not been established.
