Vor Bio announced initial clinical data from VBP101, its Phase 1/2a multicenter, open-label, first- in-human study of tremtelectogene empogeditemcel or "trem-cel" (formerly VOR33) in patients with acute myeloid leukemia (AML). The data observed from the first treated patient support the potential of a trem-cel transplant to be successfully manufactured, to engraft normally, and to maintain blood counts following treatment with the CD33-targeted therapy Mylotarg. The clinical trial continues to enroll patients and additional data are expected in 2023.
