Treatment with first-generation CAR T cells regularly sent patients to the intensive care unit. Now, investigators are envisioning a future where CAR T treatment could occur on an outpatient basis. At Sunday’s late-breaking oral session of the 2026 Annual Congress of the European Hematology Association (EHA2026), Lei Fan told his audience that the first-in-human data “support further development of LB-2501 as a potential first-in-class, off-the-shelf, single infusion, no lymphodepletion, outpatient use CAR T therapy.” Fan is a professor of hematology at the First Affiliated Hospital of Nanjing Medical University.
