Description: Daratumumab is a human monoclonal antibody that targets CD38, a cell surface glycoprotein expressed on multiple myeloma cells. It binds to CD38 protein resulting to inhibition of growth of CD38 expressing tumour cells by inducing apoptosis directly through Fc mediated cross linking as well as by immune-mediated tumour cell lysis through complement dependent cytotoxicity, antibody dependent cell mediated cytotoxicity and antibody dependent cellular phagocytosis.
Distribution: Crosses placenta. Volume of distribution: 4.7±1.3 L (monotherapy); 4.4±1.5 L (combination therapy).
Excretion: Elimination half-life: 18±9 days.
