핵심 내용

BACKGROUND: The OGA inhibitor ASN90/FNP-223 has the potential for disease modification in neurodegenerative diseases. A phase 1 clinical program in healthy participants was performed to determine its suitability for subsequent studies in movement disorders and Alzheimer's disease (AD) patients. METHODS: Clinical Study 1: A randomized, double-blind, placebo-controlled, first-in-human study to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and food effect of single and multiple doses of orally administered ASN90 in healthy adult and elderly participants. Clinical Study 2: A phase 1, open-label, positron emission tomography (PET) study in healthy participants to determine the relationship between plasma concentration and brain target occupancy of ASN90 following a single oral dose. OBJECTIVES: To assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and central nervous system (CNS) target engagement of ASN90 in healthy participants. RESULTS: ASN90 was considered safe and well tolerated with dose-proportional pharmacokinetics at steady-state up to oral doses of 500 mg twice daily. Cerebrospinal fluid-to-plasma ratios for mean peak and mean systemic exposures were in the range of 2.5%-4.6%. Investigation of CNS occupancy using a PET ligand demonstrated that target occupancy of greater than 98% in the brain of healthy participants can be achieved at doses that are clinically well tolerated. CONCLUSIONS: The phase 1 results of ASN90 in healthy participants provide strong support for its further development in progressive supranuclear palsy (PSP) and AD. Currently, Ferrer Internacional, S.A. is conducting a phase 2 study, known as PROSPER (ClinicalTrials.gov ID: NCT06355531), to evaluate the efficacy, safety, and pharmacokinetics of ASN90 in slowing the progression of PSP. © 2025 International Parkinson and Movement Disorder Society.
