drug_description
Humanized IgG monoclonal antibody (JSP191) administered subcutaneously that targets CD117 (c‑Kit), blocking SCF–c‑Kit signaling to deplete/inhibit KIT+ cells, especially tissue mast cells, thereby reducing mediator release in chronic urticaria.

Briquilimab
nci_thesaurus_definition
A humanized monoclonal antibody directed against CD117 (tyrosine-protein kinase KIT; c-Kit; mast/stem cell growth factor receptor; SCFR), that can potentially be used to deplete hematopoietic stem cells (HSCs). Upon administration, briquilimab targets and binds to CD117. This prevents the binding of stem cell factor (SCF) to its receptor CD117 on HSCs. As CD117 binding to SCF is critical for survival and maintenance of blood forming stem cells, blocking this interaction causes the HSCs that are present in the bone marrow niches to be depleted. Briquilimab can potentially be used as a conditioning regimen to prepare patients for hematopoietic stem cell transplantation.

drug_mechanism_of_action
Humanized IgG monoclonal antibody targeting CD117 (c‑Kit) that blocks stem cell factor (SCF) binding/signaling, leading to depletion or inhibition of KIT+ cells—particularly mast cells and hematopoietic stem/progenitor cells—thereby reducing mast-cell survival/activation and mediator release.
