Under the terms of the agreement, Astrogen will supply AST-001 valued at USD 131 million, and is eligible to receive up to USD 77.5 million in regulatory and commercial milestone payments,

About AST-001
AST-001 is an investigational drug candidate currently under NDA review by South Korea MFDS for the treatment of core symptoms of ASD in pediatric patients. The drug utilizes a proprietary oral syrup formulation designed to cross the blood–brain barrier and distributes to the brain. Its mechanism of action targets small conductance calcium-activated potassium (SK) channels, modulating dopaminergic signaling and restoring the excitation/inhibition (E/I) balance—one of the key pathophysiological features of ASD. AST-001 has demonstrated favorable tolerability, with clinical exposure in more than 400 subjects across clinical trials conducted in South Korea. Additionally, AST-001 has been granted Orphan Drug Designation (ODD) at the development stage in South Korea and becoming the 51st substance to receive this designation. Astrogen is actively preparing for regulatory interactions with the U.S. FDA, the EMA, and China’s NMPA to advance global development.

About Autism Spectrum Disorder (ASD)
ASD is a complex neurodevelopmental disorder characterized by persistent deficits in social communication and interaction, accompanied by restricted and repetitive behaviors. Its etiology
is multifactorial, involving genetic, environmental, and prenatal factors.


Once considered rare, ASD prevalence has risen significantly over recent decades due to improved diagnostic awareness and potential true increases in incidence. Today, more than 61 million individuals worldwide are estimated to live with ASD. The disorder affects adaptive functioning, communication, daily living, and social interaction, placing a significant burden on families and healthcare systems. Effective therapeutic options remain limited, underscoring the substantial unmet need.

South Korea, in particular, is facing a severe ASD crisis, with data showing the shortest average life expectancy for individuals with ASD among developed nations. Average age at death for persons with ASD in South Korea is only 16.6–28.2 years, significantly below peer countries such as the U.S. (36.2–39.4), Denmark (33.3), Australia (35.3), Canada (46.2), and Sweden (53.8). Currently, there is no approved pharmacological treatment for children under five, despite early childhood being a critical period for brain plasticity. The treatment gap—with currently approved therapies limited to addressing irritability or aggression but not the core symptoms of ASD—has been associated with long-term disability, premature mortality, and in extreme cases, parent–child tragedy.
