The brief
- Mar 2025: BEAM-302 made the first-ever fix of a disease-causing DNA typo in patients, raising working AAT protein.
- A ~50-patient key trial group of BEAM-302 began in Jul 2026, aiming at fast-track approval.
- An FDA filing for risto-cel in sickle cell is planned as early as end of 2026.
