Comment: Barzolvolimab (CDX-0159) is a clinical stage humanized anti-KIT IgG1 monoclonal antibody that was developed by Celldex Therapeutics (as claimed in their patent US10781267B2) [1]. CDX-0159 is a variant of CDX-0158 (a.k.a. KTN0158 [2]) that was re-engineered to improve its safety profile and increase its serum half-life. CDX-0158 was originally designed for potential to treat GIST and other KIT-dependent tumours. This original version of the antibody inhibits mutant and wild type KIT phosphorylation, reduces mast cell degranulation and mast cell numbers, and shrinks tumours in a preclinical canine model of spontaneous mast cell tumour development [2].
