BEAM‐302 decreases hepatic aggregates of mutant AAT and increases circulating functional AAT in rodent models of Alpha‐1 Antitrypsin Deficiency (ESGCT 2023) - "The PiZ mutation is an ideal target for correction to wildtype (PiM) by an adenine base editor (ABE) which converts an A to G in genomic DNA...Furthermore, repeat administration of BEAM-302 resulted in further increases in editing rates. Taken together these data support the hypothesis that base-editing by BEAM-302 has the potential to mitigate both the liver and lung pathology of AATD."
