ESCAPE (BEAM-103 & BEAM-104)

---

The ESCAPE (Engineered Stem Cell Antibody Evasion) platform is comprised of two investigational drug products: BEAM-103, an anti-CD117 monoclonal antibody (mAb) that is designed to suppress and/or eliminate hematopoietic stem and progenitor cells that express CD117, and BEAM-104, a cell therapy that includes an edit to the promoter region of the HBG1/2 genes intended to elevate HbF, plus an additional edit to CD117 designed to prevent binding of BEAM-103, allowing the edited cells to function normally and evade targeting by the antibody. Together, this approach aims to provide a non-genotoxic alternative to traditional transplant myeloablative conditioning.
