Monoclonal antibody (biologic drug)
drug_description
Also known as JSP191; a humanized monoclonal antibody administered subcutaneously that binds c-Kit (CD117), blocks SCF/c-Kit signaling, and depletes or inhibits c-Kit–expressing cells (especially mast cells) to reduce mast-cell numbers/activation and mediator release in CSU.

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 monoclonal antibody targeting c-Kit (CD117) that blocks stem cell factor (SCF)/c-Kit signaling, leading to inhibition and depletion of c‑Kit–expressing cells (notably mast cells), thereby reducing mast-cell activation and mediator release; can also deplete hematopoietic stem cells.
