Immunopharmacology Comments
CD38 is a type II transmembrane glycoprotein, that is widely expressed on immune cells and is involved in cell adhesion and signal transduction. Its extracellular domain acts as an ectoenzyme, catalyzing the conversion of nicotinamide adenine dinucleotide (NAD+) into nicotinamide, adenosine diphosphate-ribose (ADPR), and cyclic ADPR. Expression of CD38 is tightly regulated during B-cell development and maturation [6]. Since CD38 is expressed in a subset of haematological tumours, particularly in plasma cell tumours such as multiple myeloma (MM), anti-CD38 monoclonal antibodies have been developed with immuno-oncology potential as their main indication. Daratumumab (a MM therapeutic) was the first-in-class anti-CD38 antibody to reach the clinic. Additional investigational CD38-targeting antibodies include isatuximab (SAR650984, ImmunoGen) [3], MOR202 (MorphoSys) [1], AT13/5 (Tenovus Research) [5] and mezagitamab (Takeda) [10], which were all primarily developed for MM and other haematological cancers. However, anti-CD38 monoclonals may have applications in the treatment of diseases in addition to haematological malignancies, including solid tumours and antibody-mediated autoimmune diseases.
