CAMBRIDGE, Mass., Aug. 09, 2022 (GLOBE NEWSWIRE) -- Beam Therapeutics Inc. (Nasdaq: BEAM), a biotechnology company developing precision genetic medicines through base editing, today provided pipeline and business updates and reported financial results for the second quarter ended June 30, 2022.

“2022 is a critical year for Beam’s transition to becoming a multi-program clinical-stage company, as we prepare for the near-term initiation of patient enrollment in our BEACON Phase 1/2 trial, the first clinical trial evaluating BEAM-101 in patients with sickle cell disease,” said John Evans, chief executive officer of Beam. “In June, we submitted our IND for BEAM-201 for CD7-positive T-cell malignancies and recently received notification from the FDA of a clinical hold on the IND. We look forward to receiving more detail from the FDA and working with them in an effort to advance BEAM-201 for these difficult-to-treat cancer indications. We are on track to further expand our portfolio with a steady cadence of clinical and preclinical milestones expected in the quarters ahead, including the IND submission for BEAM-102, our second program in sickle cell disease, and the initiation of IND-enabling studies for BEAM-301, our first liver-directed base editing program in glycogen storage disease, both targeted in the second half of this year.”

Mr. Evans added, “As pioneers and leaders in the field of base editing, we’ve continued to extend the potential reach of our base editing technology and applications with the development of new base editors, as well as novel base editing-enabled therapeutic strategies, such as our work on non-genotoxic conditioning to improve transplant regimens. We’ve also continued to enhance our team, and I’m thrilled to welcome John Lo as chief commercial officer. John has a deep science background and an extensive track record in the strategic development and commercialization of novel medicines, including cell therapy products, at leading companies. I can’t wait to work with him to advance our portfolio and our vision of providing a new class of precision genetic medicines to patients.”

Pipeline Updates & Anticipated Milestones
Ex Vivo HSC Programs

  • Beam remains on track to begin patient enrollment in its BEACON trial, an open-label, single-arm, multicenter, Phase 1/2 clinical trial evaluating the safety and efficacy of BEAM-101 in adult patients with severe sickle cell disease (SCD) in the second half of 2022.
  • BEAM-102 continues to progress, and the company plans to submit an investigational new drug (IND) application for BEAM-102 for the treatment of SCD in the second half of 2022.

Ex Vivo T Cell Programs

  • Beam submitted its IND for BEAM-201 to the U.S. Food and Drug Administration (FDA) in June 2022, and on July 29, 2022, was notified via e-mail that the IND was placed on clinical hold. The FDA indicated it will provide an official clinical hold letter to Beam within 30 days. Beam plans to provide additional updates pending interaction with the FDA.
  • Beyond BEAM-201, Beam is focused on identifying the collection of multiplex base edits required to make cells fully allogeneic, with internal and external data suggesting a higher number of edits will be required to meet this goal. As a result, Beam does not expect to nominate a second CAR-T development candidate in 2022 and anticipates providing further updates in 2023.

In Vivo LNP Liver-targeting Programs

  • Beam presented updated preclinical data from its BEAM-301 program at the American Society of Cell and Gene Therapy (ASGCT) meeting, highlighting that BEAM-301 demonstrated high and durable editing efficiency in a mouse model of glycogen storage disease 1a (GSDIa) out to 35 weeks. BEAM-301, a liver-targeting lipid nanoparticle (LNP) formulation of base editing reagents designed to correct the R83C mutation, the most common disease-causing mutation of GSDIa, is on track for initiation of IND-enabling studies in the second half of 2022.
  • At ASGCT, Beam also presented new preclinical data from its base editing program targeting the treatment of alpha-1 antitrypsin deficiency, highlighting optimizations made to the editor and the guide RNA that have led to two-fold increases in observed editing potency in mice, leading to potentially clinically relevant increases in circulating alpha-1 antitrypsin at doses below 1 mg/kg.
  • Beam plans to present new in vivo preclinical data from its multiplex base editing program for the potential treatment of hepatitis B virus (HBV) in a poster titled, “Cytosine base editing inhibits Hepatitis B Virus replication and reduces HBsAg expression in vitro and in vivo,” at the 2022 International HBV Meeting from Sept. 18-22. The data will build on initial in vitro data presented in September 2021, which showed that base editing can introduce permanent mutations in covalently closed circular DNA (cccDNA) and prevent HBV rebound in relevant models.
  • Beam continues to anticipate the nomination of a second liver-targeted development candidate in 2022.

Recent Research Highlights

  • At the Federation of American Societies for Experimental Biology (FASEB) Genome Engineering Conference in June, Beam presented the first research highlighting the company’s internal efforts to develop improved transplant conditioning regimens for patients with SCD undergoing hematopoietic stem cell transplantation (HSCT). With a goal of overcoming limitations of today’s conditioning regimens, Beam leveraged its base editing capabilities to develop a potentially non-genotoxic approach that combines antibody-based conditioning with multiplex gene-edited hematopoietic stem cells (HSCs) called ESCAPE, or Engineered Stem Cell Antibody Paired Evasion. These improved conditioning regimens could potentially be paired with BEAM-101 and BEAM-102, as well as other future programs.
  • At the CRISPR 2.0 conference in June, Beam highlighted research that led to the creation of an improved class of cytosine base editors (CBEs), leveraging a TadA enzyme-based CBE (CBE-T), that are capable of editing at levels comparable to traditional CBEs but with lower off-target editing potential. Further, Beam disclosed an additional editor, CABE-T, that can conduct both C-to-T and A-to-G edits with a single TadA deaminase.

Business Updates

  • Beam recently appointed John Lo, Ph.D., as chief commercial officer, where he will be responsible for commercial readiness, as well as leading product and portfolio strategy. Dr. Lo joins Beam after serving as an advisor to multiple private- and public-stage biotechnology companies, including Beam. Dr. Lo has held a number of global strategic and operating roles of increasing responsibility within the biopharmaceutical industry, including as senior vice president, worldwide hematology at Bristol Myers Squibb; head of global marketing and market access at Astra Zeneca; corporate vice president, hematology and oncology at Celgene; and multiple P&L roles at Novartis. While at these companies, Dr. Lo successfully helped launch numerous drugs in the U.S. and globally, including Tagrisso in lung cancer and two cell therapies. Dr. Lo has also helped build strategies and grow R&D pipelines as co-chair of the Development Committee at Celgene, leading to multiple pivotal study investments. Dr. Lo also spent several years as an associate principal at McKinsey & Company and holds a Ph.D. in molecular biology from MIT.
  • In July, Beam and Verve Therapeutics amended their collaboration and license agreement, originally executed in April 2019. The amended agreement returned two targets to Beam, while adding a new, third target toward an additional liver-mediated, cardiovascular disease target. Beam has the right to opt in on this target after Phase 1 to share 35% of worldwide costs and profits from the program. The two lead targets in the collaboration, PCSK9 and ANGPTL3, are unchanged. Verve also granted to Beam licenses and options to certain delivery technologies.

Second Quarter 2022 Financial Results

  • Cash Position: Cash, cash equivalents and marketable securities were $1.2 billion as of June 30, 2022, as compared to $965.6 million as of December 31, 2021.
  • Research & Development (R&D) Expenses: R&D expenses were $74.6 million for the second quarter of 2022, compared to $45.6 million for the second quarter of 2021.
  • General & Administrative (G&A) Expenses: G&A expenses were $24.1 million for the second quarter of 2022, compared to $13.4 million for the second quarter of 2021.
  • Net Loss: Net loss was $72.0 million for the second quarter of 2022, or $1.02 per share, compared to $76.3 million for the second quarter of 2021, or $1.23 per share.
