Company to Host Conference Call Today, November 5, 2024, at 8:30 a.m. ET

CAMBRIDGE, Mass., Nov. 05, 2024 (GLOBE NEWSWIRE) -- Beam Therapeutics Inc. (Nasdaq: BEAM), a biotechnology company developing precision genetic medicines through base editing, today reported third quarter 2024 financial results and provided updates across the company’s hematology and genetic disease franchises.

“In the third quarter, we demonstrated strong execution across our priority hematology and liver genetic disease programs, with progress in clinical site activation, patient enrollment and dosing,” said John Evans, chief executive officer of Beam. “The imminent presentation of our BEAM-101 clinical data in patients with sickle cell disease, along with preclinical data for ESCAPE, at the ASH Annual Meeting is an important milestone for Beam’s base editing technology. In our in vivo portfolio, the BEAM-302 clinical program in alpha-1 antitrypsin deficiency is expanding globally, with dosing complete for the first cohort of patients and data anticipated in 2025, while BEAM-301 has achieved an open IND with the FDA upon first review. We are now entering a catalyst-rich period for Beam, with a strong cash position supporting both the execution of our development programs and our long-term investment in a highly differentiated product engine.”

Third Quarter 2024 and Recent Progress

• Four Beam abstracts were accepted for presentation at the upcoming American Society of Hematology (ASH) Annual Meeting, including two abstracts on the initial clinical data from the BEACON trial of BEAM-101, one on the clinical data for BEAM-201, and one on the preclinical non-human primate (NHP) data for the Engineered Stem Cell Antibody Paired Evasion (ESCAPE) conditioning platform. Beam will host an investor webcast and conference call today at 8:30 a.m. ET to review the abstracts. Abstracts will be available on the ASH website today at 9 a.m. ET.
• To date, 35 patients have cleared screening and enrolled in the BEACON Phase 1/2 clinical trial of BEAM-101, an investigational genetically modified cell therapy for the treatment of sickle cell disease (SCD). Of these patients, eight have been dosed with BEAM-101, with the other enrolled patients going through pre-transplant stages, including cell collection and drug product manufacturing.
• Patient enrollment in the Phase 1/2 clinical trial of BEAM-302 in patients with alpha-1 antitrypsin deficiency (AATD) is progressing, with continued site activation globally and dosing completed for the first cohort.
• Beam has nominated a development candidate for its ESCAPE technology comprised of two investigational drug products: BEAM-103, an anti-CD117 monoclonal antibody (mAb), and BEAM-104, a cell therapy that includes the same therapeutic edit as BEAM-101 (editing the HBG1/2 genes to elevate fetal hemoglobin), plus an additional edit to CD117 which is designed to prevent binding of BEAM-103, allowing the edited cells to evade suppression by the antibody. The company intends to advance BEAM-103 and BEAM-104 for development in SCD and beta-thalassemia, potentially building on the same regulatory, manufacturing, clinical and commercial foundations being established for BEAM-101.

Key Anticipated Milestones

Hematology Franchise

• In conjunction with the ASH Annual Meeting taking place December 7-10, 2024, Beam will present additional data from the BEACON Phase 1/2 clinical trial of BEAM-101 and additional preclinical NHP data for ESCAPE. The company will host an investor event to review the data on Sunday, December 8, at 8 p.m. PT.
• The company anticipates initiating Phase 1-enabling preclinical studies for ESCAPE by the end of 2024.

Genetic Disease Franchise

• Beam expects to report initial clinical data from multiple cohorts in the Phase 1/2 clinical trial of BEAM-302 in patients with AATD in 2025.
• The company is continuing site activation activities for the Phase 1/2 clinical trial for BEAM-301 in glycogen storage disease type 1a (GSDIa), with patient dosing expected to commence in early 2025.

Oncology

• Data from the Phase 1/2 clinical trial of BEAM-201, a multiplex-edited allogeneic CAR-T product candidate for the treatment of relapsed/refractory T-cell acute lymphoblastic leukemia (T-ALL)/T-cell lymphoblastic lymphoma (T-LL), will be presented at the ASH Annual Meeting.
  

Third Quarter 2024 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities were $925.8 million as of September 30, 2024, compared to $1.2 billion as of December 31, 2023.
• Research & Development (R&D) Expenses: R&D expenses were $94.3 million for the third quarter of 2024, compared to $100.0 million for the third quarter of 2023.
