Overview
Beam Therapeutics is pioneering base editing, a next-generation gene editing technology that enables precise, predictable, and efficient single-base changes in the genome without making double-strand DNA breaks. Founded by base editing inventors David Liu, J. Keith Joung, and Feng Zhang, the company's proprietary base editors — adenine base editors (ABEs) and cytosine base editors (CBEs) — convert one DNA base pair to another with high precision and minimal unintended edits. The company's therapeutic pipeline targets sickle cell disease, beta-thalassemia, alpha-1 antitrypsin deficiency, and glycogen storage diseases using ex vivo base editing of patient cells. In oncology, Beam is developing multiplexed base editing to create allogeneic CAR-T cell therapies with multiple simultaneous edits that prevent immune rejection and enhance persistence. BEAM-101 has entered Phase 1/2 clinical trials for sickle cell disease. Beam's differentiation lies in the fundamental safety advantage of base editing over standard CRISPR: by avoiding double-strand breaks, base editors reduce the risk of large deletions, translocations, and chromosomal rearrangements associated with DSB-based editing. The company also holds in-licensing rights to prime editing technology from David Liu's laboratory, providing access to the broadest suite of precision editing tools available for drug development.
