Well-Capitalized with $1.1B in Cash, Cash Equivalents and Marketable Securities at the End of the Second Quarter of 2023

CAMBRIDGE, Mass., Aug. 08, 2023 (GLOBE NEWSWIRE) -- Beam Therapeutics Inc. (Nasdaq: BEAM), a biotechnology company developing precision genetic medicines through base editing, today reported second quarter 2023 financial results and provided an update on its clinical and pipeline progress.

“The first half of 2023 has been marked by focused execution across the business, with the singular goal of making an impact on the lives of people suffering from serious diseases,” said John Evans, chief executive officer of Beam. “We are very pleased with the continued enrollment progress in the BEACON trial, having now consented enough patients projected to both fill the sentinel cohort and initiate the expansion cohort. In addition, the BEAM-201 trial is now open for enrollment at multiple clinical sites, with the first patient having been consented and dosing expected this quarter. We have also continued to accelerate development of BEAM-302, a potential best-in-class product candidate for patients with alpha-1 anti-trypsin deficiency, and are now prioritizing a BEAM-302 regulatory filing in the first quarter of 2024 as our first in vivo program, with a regulatory filing for BEAM-301 expected to follow shortly thereafter. Our critical manufacturing capability in North Carolina is anticipated to be cGMP ready for both cell manufacturing and LNP manufacturing this year. Finally, Beam is well capitalized to pursue the next wave of growth in its innovative research platform, from non-genotoxic conditioning with ESCAPE in hematology, to next-generation allogeneic cell therapies in cancer and immunology, to a growing number of wholly owned and partnered base editing programs targeting the liver. We believe we are well positioned to establish an industry-leading platform in precision genetic medicine.”

Second Quarter 2023 Business Updates and Key 2023-2024 Anticipated Milestones

Hematology Portfolio

  • Beam continues to advance its BEACON Phase 1/2 clinical trial, an open-label, single-arm, multicenter study evaluating the safety and efficacy of BEAM-101 in adult patients with severe sickle cell disease (SCD).
    • Beam has continued to consent additional patients in the BEACON trial, all of whom are now moving in parallel through the screening, transfusion and mobilization activities required to enable treatment with BEAM-101.
    • Beam now anticipates that currently consented patients are sufficient to both fill the sentinel cohort (n=3) and to initiate the expansion cohort. Beam will continue adding additional patients to the BEACON trial through the end of year and beyond, with a total target of 45 treated patients.
    • Treatment with BEAM-101, in which the edited cell product is delivered in an autologous bone marrow transplant, will occur on a sequential basis for the first three patients treated in the trial, and then will be given in parallel for all subsequent patients.
    • The company continues to anticipate reporting initial data on multiple patients from the BEACON trial in 2024.
  • Beam continues to advance and invest in its Engineered Stem Cell Antibody Paired Evasion (ESCAPE) conditioning platform.

Immunology/Oncology Portfolio

  • Beam continues to advance 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). Multiple sites for the Phase 1/2 clinical trial of BEAM-201 are now open for enrollment.
  • The first patient has consented and is expected to be dosed in the third quarter of 2023.
  • Beam also continues to invest in and advance its next-generation allogeneic strategies designed to improve cell persistence and expand the utility and accessibility of cell therapies in cancer and other diseases. The company plans to share updates on these efforts by year-end 2023.

Genetic Disease (in vivo) Portfolio

  • Beam continues to advance its two in vivo base editing product candidates, BEAM-301 for the treatment of glycogen storage disease 1a (GSD1a) and BEAM-302 for the treatment of alpha-1 antitrypsin deficiency (AATD), leveraging lipid nanoparticles (LNPs) for delivery to the liver.
  • To promote speed to the clinic of a top priority program, the company has leveraged the learnings and capability build from BEAM-301 to accelerate development of BEAM-302, which is now expected to be its first in vivo liver regulatory filing, followed by BEAM-301.
  • The company expects to:
    • Submit a regulatory application for authorization to initiate clinical trials for BEAM-302 in the first quarter of 2024; and
    • Submit a regulatory application for authorization to initiate clinical trials for BEAM-301 in the first half of 2024.
  • Beam continues to advance multiple additional in vivo editing programs targeting the liver, including both its wholly owned and collaboration programs, through lead optimization, and advance its LNP delivery technologies for delivery of base editing medicines to the liver and other tissues.

Manufacturing Updates

  • Beam continues to expect initiation of current good manufacturing practice compliant operations at its North Carolina manufacturing facility in late 2023.
  • Beam is now planning to enable cGMP manufacturing of both autologous cell products in support of its sickle cell programs as well as LNP products in support of its liver programs BEAM-302 and BEAM-301 in its North Carolina facility.

Recent Nature Genetics Preclinical Publication Suggests Base Editing Enables More Uniform HbF Upregulation than Nuclease Editing

  • In July, Beam co-founder David Liu, Ph.D., and St. Jude Children’s Research Hospital collaborators Jonathan Yen, Ph.D., and Mitchell Weiss, M.D., Ph.D., published preclinical research comparing five gene editing strategies in CD34+ hematopoietic stem and progenitor cells using either Cas9 nuclease or adenine base editors to induce fetal hemoglobin (HbF) red blood cells. Notably, the data suggest that base editing can provide a strategy for potent, uniform induction of HbF, yielding a consistent, predictable, and precise editing outcome. Conversely, nuclease editing of either the fetal hemoglobin gene or the BCL11A enhancer created a complex, uncontrolled distribution of alleles with a wide range of outcomes for induction of fetal hemoglobin, including numerous cells with minimal or no induction detected. These data illustrate the potential advantages of base editing’s mechanism of action, including the creation of predictable and consistent gene modifications with well-characterized, uniform biological effects across edited cells, as compared to the uncontrolled mixture of allele outcomes that result from nuclease-based knockout through double-stranded breaks.

Second Quarter 2023 Financial Results

  • Cash Position: Cash, cash equivalents and marketable securities were $1.1 billion as of June 30, 2023, as compared to $1.1 billion as of December 31, 2022.
  • Research & Development (R&D) Expenses: R&D expenses were $97.6 million for the second quarter of 2023, compared to $74.6 million for the second quarter of 2022.
  • General & Administrative (G&A) Expenses: G&A expenses were $24.7 million for the second quarter of 2023, compared to $24.1 million for the second quarter of 2022.
  • Net Loss: Net loss was $82.8 million for the second quarter of 2023, or $1.08 per share, compared to $72.0 million for the second quarter of 2022, or $1.02 per share.

Cash Runway

Beam expects that its cash, cash equivalents and marketable securities as of June 30, 2023, will enable the company to fund its anticipated operating expenses and capital expenditure requirements at least into 2025. This expectation includes funding directed toward reaching each of the key anticipated milestones for BEAM-101, BEAM-201, BEAM-301 and BEAM-302 described above, as well as continued investments in platform advancements and manufacturing capabilities.
