"From the beginning, [our] strategy has been to develop base-editing technology broadly across a diverse portfolio of programmes and delivery modalities, and our science and pipeline continue to progress across the board," stated CEO John Evans. However, he said that "in this challenging market environment…we need to make the difficult decision to focus our resources on those clinical programmes and research areas we believe have the highest potential for near-term value creation."
Seeking partners for CAR-T programmes
The company says it will be prioritising development of its ex vivo and in vivo SCD programmes, including the autologous haematopoietic cell therapy BEAM-101, which is in Phase I/II testing, as well as its engineered stem cell antibody paired evasion (ESCAPE) strategy, and in vivo delivery to hematopoietic stem cells. Focus remains on Beam's preclinical in vivo base editor BEAM-302 for the treatment of AATD as well. Meanwhile, the company plans an initial trial for BEAM-301, a liver-targeting lipid nanoparticle formulation of base editing reagents designed to correct the R83C mutation, the most common disease-causing mutation associated with a severe form of glycogen storage disease 1a. It is also looking to generate a "focused clinical dataset" for its off-the-shelf, quadruplex-edited CAR-T candidate BEAM-201 for T-cell acute lymphoblastic leukaemia, while scouting for potential partners to help advance this and other ex vivo CAR-T programmes. The company is currently running a Phase I trial of BEAM-201, after it was put on clinical hold by the FDA last year and subsequently lifted in December. Hepatitis B programme paused
Meanwhile, Beam said that its hepatitis B virus programme will be "paused and designated for partnering given the requirement of specialised development and commercial capabilities." The company noted that it will focus its near-term investments on certain in vivo editing capabilities in the liver targeting both rare genetic and common disorders, as well as "select opportunities" in haematology and immunology/oncology. Beam said the workforce reduction is expected to be completed in the fourth quarter. Once all the cost-cutting measures are put in place, it anticipates that savings from the plan, as well as its balance of cash and equivalents of $1.1 billion, will be sufficient to fund operations until 2026, compared to a previous projection of at least 2025.
