Beam Therapeutics Reports Pipeline Updates and First Quarter 2024 Financial Results

Dosing Completed for Sentinel Cohort of BEACON Phase 1/2 Trial of BEAM-101 in Severe Sickle Cell Disease; Expansion Cohort Initiated

Clinical Trial Authorisation (CTA) Application Cleared for the Phase 1/2 Trial of BEAM-302 in Alpha-1 Antitrypsin Deficiency; Study to Initiate in First Half of 2024

BEAM-301 On Track for Submission of U.S. Investigational New Drug (IND) Application in First Half of 2024

Ended First Quarter 2024 with $1.1 Billion in Cash, Cash Equivalents and Marketable Securities; Cash Runway Expected to Support Operating Plans into 2027

CAMBRIDGE, Mass., May 07, 2024 (GLOBE NEWSWIRE) -- Beam Therapeutics Inc. (NASDAQ:BEAM), a biotechnology company developing precision genetic medicines through base editing, today reported first quarter 2024 financial results and provided updates across the company's hematology and genetic disease franchises.

"We're pleased to share progress across our high-priority programs that exemplify our commitment to rapid, focused execution and a dedication to developing differentiated, one-time medicines for serious genetic diseases," said John Evans, chief executive officer of Beam. "We have successfully completed dosing and engraftment for three sickle cell disease patients in the sentinel cohort of the BEAM-101 BEACON trial allowing us to now move forward with expansion phase dosing. We look forward to sharing data for multiple patients treated with BEAM-101 later this year. In addition, our team has done an incredible job executing our ex-U.S. clinical strategy for BEAM-302, securing CTA clearance in the UK and rapidly working toward the initiation of our Phase 1/2 trial in patients with alpha-1 antitrypsin deficiency. This study is designed to demonstrate proof-of-concept for correction of the disease-causing mutation that could potentially help patients with both lung and liver disease manifestations. These updates, supported by our robust balance sheet, mark a significant stride toward our goal of establishing base editing as a potentially transformative and differentiated therapeutic option for patients in need."

First Quarter 2024 and Recent Progress

• Sequential dosing and engraftment have been successfully completed for the three patients in the sentinel cohort of the BEACON Phase 1/2 clinical trial of BEAM-101 in severe sickle cell disease.
• Following clearance by the data monitoring committee, the expansion cohort of the BEACON trial of BEAM-101, in which patients can be dosed in parallel, is now open with dosing expected to begin imminently.
• In March 2024, Beam announced the clearance of its clinical trial authorisation (CTA) application by the United Kingdom (UK) Medicines and Healthcare Products Regulatory Agency for BEAM-302, the company's priority genetic disease program for the treatment of alpha-1 antitrypsin deficiency (AATD).
