Patient Dosing and Enrollment Continue to Progress in Beacon Phase 1/2 Study of BEAM-101 in Severe Sickle Cell Disease; First Clinical Data Anticipated in Second Half of 2024

Phase 1 Trial Initiation for BEAM-302 in Alpha-1 Antitrypsin Deficiency on Track for First Half of 2024 Pending European Clinical Trial Application (CTA) Acceptance

Ended Fourth Quarter 2023 with $1.2 Billion in Cash, Cash Equivalents and Marketable Securities; Cash Runway Expected to Support Operating Plans into 2027

CAMBRIDGE, Mass., Feb. 27, 2024 (GLOBE NEWSWIRE) -- Beam Therapeutics Inc. (Nasdaq: BEAM), a biotechnology company developing precision genetic medicines through base editing, today reported fourth quarter and full year 2023 financial results and reiterated anticipated milestones across the company’s sickle cell disease and genetic disease portfolios.

“This year has the potential to be transformative for Beam as we work to advance multiple base editing programs in the clinic, anchoring key high-value franchises through near-term catalysts – all backed by a strong balance sheet,” said John Evans, chief executive officer of Beam. “In 2024, we expect to initiate our first in vivo clinical studies and report the first in-human data from our ex vivo base editing clinical programs. Operationally, we’ve made significant progress in the BEACON study of BEAM-101 in sickle cell disease, and we’re on track to complete the sentinel cohort and initiate dosing in the expansion cohort in the first half of the year. In addition, we filed our CTA for BEAM-302 in alpha-1 anti-trypsin deficiency ahead of schedule and remain on track to initiate that study in the first half of 2024. We are convinced that base editing has the potential to provide new options and meaningful advantages over existing therapies for patients suffering from serious diseases.”

Key 2024 Anticipated Milestones

Sickle Cell Disease (SCD) Franchise

• In the BEACON Phase 1/2 clinical trial of BEAM-101 in adults with severe SCD, Beam anticipates completing dosing in patients in the sentinel cohort and initiating dosing in patients in the expansion cohort in the first half of 2024.
