What is APR-548?

APR-548 is an orally administered prodrug that is converted to the active compound 2-methylene-quinuclidin-3-one, which binds mutant p53 at its DNA-binding domain and restores wild-type p53 structure and activity. It is being studied in myelodysplastic syndromes, alone and in combination with azacitidine.
