Company On-track to Submit First IND for BEAM-101 in the Second Half of 2021

Continued Progress Across Base Editing Portfolio, Including Initiation of IND-Enabling Studies for BEAM-201

CAMBRIDGE, Mass., Aug. 10, 2021 (GLOBE NEWSWIRE) -- Beam Therapeutics Inc. (Nasdaq: BEAM), a biotechnology company developing precision genetic medicines through base editing, today reported recent business and pipeline updates, as well as second quarter 2021 financial results.

“We have made meaningful progress in advancing our base editing programs in the first half of the year, and importantly, remain on track to submit our first investigational new drug (IND) for BEAM-101 in the second half of this year,” said John Evans, chief executive officer of Beam. “With the initiation of IND-enabling studies for BEAM-201, we are now bringing the versatility and precision of base editing to a second therapeutic area, targeting the high unmet need in T-cell cancers with the first quad-edited cell therapy.  We’ve also continued to expand our innovative collaborator network, most recently through our partnership with Apellis to apply base editing to the more biologically complex disease area of the complement pathway. With a strong balance sheet, we are well positioned to advance our robust pipeline of novel base editing programs through IND filings and into the clinic as we strive to provide potentially life-long cures for patients suffering from serious diseases.”

Base Editing Pipeline Progress

  • IND-Enabling Studies for BEAM-201 Initiated: Beam has initiated IND-enabling studies for BEAM-201 for the treatment of relapsed/refractory T-cell acute lymphoblastic leukemia (T-ALL). BEAM-201 is a potent and specific allogeneic CAR-T targeting CD7+ malignancies, which uses multiplex base editing to simultaneously make four knockout edits at over 96% efficiency for each gene.  Relapsed/refractory T-ALL is a severe disease affecting children and adults with a five-year overall survival rate of less than 25%.

  • Additional Upcoming Milestones in Ex Vivo and In Vivo Base Editing Pipeline On Track: Beam anticipates filing an IND for BEAM-101, which reproduces single base changes seen in individuals with Hereditary Persistence of Fetal Hemoglobin, or HPFH, to potentially protect them from the effects of mutations causing sickle cell disease (SCD), and initiating IND-enabling studies for BEAM-102, which directly corrects the causative mutation in SCD by recreating a naturally-occurring normal human hemoglobin variant, both in the second half of 2021.  Beam is also on track to nominate its first Development Candidate for in vivo base editing of the liver using LNP delivery by the end of 2021.

  • Data Highlighting Base Editing Approach for the Treatment of Alpha-1 Antitrypsin Deficiency Published in Molecular Therapy: In July 2021, data from a preclinical study led by the Center for Regenerative Medicine at Boston Medical Center and Boston University evaluating Beam’s base editors in induced pluripotent stem cells (iPS cells) from patients with alpha-1 antitrypsin deficiency (AATD) were published in Molecular Therapy. As part of the study, the researchers utilized patient-derived liver cells that mimic the biology of liver hepatocytes, the main producers of alpha-1 antitrypsin protein in the body, that likewise perform important metabolic, endocrine and secretory functions. The data showed that Beam’s base editors corrected the mutation in the gene responsible for AATD and reduced the effects of the disease in the hepatocytes, demonstrating successful base editing in human cells.

Upcoming Base Editing Data Presentations

  • Data from Sickle Cell Disease Program to be Presented at Cold Spring Harbor Laboratory’s Genome Engineering: CRISPR Frontiers: Beam plans to present preclinical data highlighting its approach to using adenine base editing (ABE) for the treatment of sickle cell disease, including updated safety data during an oral session at the Cold Spring Harbor Laboratory’s Genome Engineering: CRISPR Frontiers Conference. Details of the presentation are as follows:

    Title: Adenine base editing strategy for the treatment of sickle cell disease by elimination of the pathogenic globin protein
    Session: Disease/Therapeutic
    Date: Friday, August 20, 2021, 2:30 -5:30 p.m. ET

  • Updated Data on Optimization of LNP Delivery Approach to be Presented at TIDES 2021: Beam plans to present preclinical data highlighting work to optimize its lipid nanoparticles (LNPs) for the delivery of mRNA encoding a base editor and guide RNA to hepatocytes in the liver during an oral session at the TIDES USA Oligonucleotide & Peptide Therapeutics Conference. Details of the presentation are as follows:
                 
    Title: Optimization of LNP for in vivo Base Editing in Liver
    Track: mRNA and Genome Editing TRACK: Emerging Genome Editing Technologies
    Date/Time: Thursday, September 23, 2021, 11:15 a.m. - 11:45 a.m. ET

Business Highlights

  • Groundbreaking on Internal Manufacturing Facility to Support Future Product Development: In July 2021, Beam broke ground on its 100,000 square foot current Good Manufacturing Practice (cGMP) compliant manufacturing facility in Research Triangle Park, North Carolina. The facility will be designed to support manufacturing for Beam’s ex vivo cell therapy programs in hematology and oncology and in vivo non-viral delivery programs for liver diseases, with flexibility to support manufacturing of its viral delivery programs, and ultimately, scale-up to support commercial supply. Beam expects the facility to be operational in 2023. 

  • Exclusive Research Collaboration Executed with Apellis to Apply Base Editing to Discover Novel Therapies for Complement-Driven Diseases: In June 2021, Beam and Apellis Pharmaceuticals, Inc. (Apellis) announced an exclusive five-year research collaboration focused on the use of Beam’s proprietary base editing technology to discover new treatments for complement-driven diseases. Under the terms of the collaboration agreement, Beam will apply its base editing technology and conduct preclinical research on up to six base editing programs that target specific genes within the complement system, including C3, in various organs, including the eye, liver and brain. Apellis will have exclusive rights to license each of the six programs and will assume responsibility for subsequent development. Apellis agreed to pay a total of $75 million in upfront and near-term milestones to Beam. Beam is also eligible to receive development, regulatory and sales milestones, as well as royalty payments on sales of licensed products. Beam may also elect to enter into a 50-50 U.S. co-development and co-commercialization agreement with Apellis with respect to one program licensed under the collaboration.

Second Quarter 2021 Financial Results

  • Cash Position: Cash, cash equivalents and marketable securities were $615.3 million as of June 30, 2021, compared to $299.7 million as of December 31, 2020.
