Develops RNA-editing medicines through the Axiomer platform, with AX-0810 in a first-in-human study for cholestatic diseases. The clinical-stage company shifted away from inherited-retinal-disease programs and maintains a liver and nervous-system collaboration with Eli Lilly.
Develops RNA-editing medicines using Axiomer, a platform that employs endogenous ADAR machinery to make targeted single-nucleotide RNA edits. The platform supports programs intended to correct or modulate RNA, following the 2022 shift away from inherited-retinal-disease programs.
AX-0810, an NTCP-targeting editing oligonucleotide for cholestatic diseases, leads the internal pipeline in a first-in-human Phase 1 study. AX-0811 is in late non-clinical development, and AX-0422 targets Hurler syndrome in non-clinical development.
Based in Leiden, the Netherlands, with a U.S. office in Cambridge, Massachusetts, the clinical-stage organization also works with Eli Lilly on potential medicines for genetic disorders in the liver and nervous system. Progress depends on clinical-trial execution and regulatory interactions.
