Beam Therapeutics to Present New Preclinical Data Highlighting Non-Genotoxic Conditioning Regimens for Patients with Sickle Cell Disease Ahead of Autologous Transplant at the 64th ASH Annual Meeting
Beam Therapeutics (Nasdaq: BEAM) will present significant data on its Engineered Stem Cell Antibody Paired Evasion (ESCAPE) approach at the 64th Annual American Society of Hematology (ASH) Meeting from December 10-13, 2022. The ESCAPE strategy aims to enhance the safety of treatments for sickle cell disease (SCD) by combining antibody-based conditioning with multiplex gene-edited hematopoietic stem cells. Data on the ESCAPE-1 and ESCAPE-2 approaches, which focus on optimizing fetal hemoglobin levels and reducing toxicity, will be showcased, underpinning Beam's commitment to improving patient outcomes in hematologic diseases.
- Presenting data on ESCAPE-1 and ESCAPE-2 at ASH Meeting, potentially advancing treatment strategies for SCD.
- Innovative approach targeting toxicity in conditioning regimens could enhance patient safety and treatment efficacy.
- Progress in Wave 2 strategy aligns with long-term vision for broadening accessibility of base editing therapies.
- Dependence on upcoming clinical trial results for future validation of the ESCAPE strategy.
CAMBRIDGE, Mass., Nov. 03, 2022 (GLOBE NEWSWIRE) -- Beam Therapeutics Inc. (Nasdaq: BEAM), a biotechnology company developing precision genetic medicines through base editing, today announced that new data supporting the advancement of its Engineered Stem Cell Antibody Paired Evasion (ESCAPE) conditioning approach will be presented during poster sessions at the 64th Annual American Society of Hematology (ASH) Annual Meeting and Exposition. The meeting is being held December 10-13, 2022, in New Orleans.
Beam is advancing ESCAPE as part of its long-term strategy to support broad accessibility of base editing treatments for patients with sickle cell disease (SCD) and other hematologic diseases. A key component of the company’s Wave 2 strategy is focused on improving the safety and tolerability of conditioning regimens, a required pretreatment for patients receiving ex vivo gene editing treatment via autologous transplant. To address toxicity challenges associated with currently available conditioning regimens, Beam has 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).
The data to be presented at ASH expand upon data presented earlier this year for its ESCAPE-1 approach, which consists of multiplex base edited HSCs that include a therapeutic edit for SCD at the HGB1/2 gene designed to enable upregulation of fetal hemoglobin and an additional simultaneous edit at CD117. Findings showed that the edit-antibody pair targeting CD117, an optimal conditioning target for eliminating HSCs, led edited HSCs to function normally but escape the binding of the conditioning antibody. In addition, Beam will present work on ESCAPE-2, in which the company leveraged its initial ESCAPE work to screen guides that were compatible, in a multiplex-edited HSC, with a next-generation adenine base editor that could install the therapeutic HbG-Makassar edit.
“Improving conditioning regimens for patients ahead of autologous transplant is a key focus for Beam as part of Wave 2 of our long-term strategy to bring best-in-class base editing treatments to people with SCD,” said Giuseppe Ciaramella, Ph.D., president and chief scientific officer of Beam. “We are advancing our ex vivo programs with standard conditioning under our Wave 1 strategy and are excited by this Wave 2 progress with both our ESCAPE-1 and ESCAPE-2 approaches, which have the potential to expand the number of patients who may benefit from our therapies. These conditioning strategies take advantage of the strengths of base editing for precise, efficient, multiplex editing without double stranded breaks, and we are encouraged by the rapid progress we are making on our vision for a potentially non-genotoxic approach for conditioning in HSC transplant. This work is an integral part of our SCD portfolio strategy, and we believe it may also open many other potential applications in hematology. We look forward to presenting these data at the upcoming ASH Annual Meeting.”
