Popis: Abstract Background CD38 has been established as an important therapeutic target for multiple myeloma (MM), for which two CD38 antibodies are currently approved—daratumumab and isatuximab. CD38 is an ectoenzyme that degrades NAD and its precursors and is involved in the production of adenosine and other metabolites. Aim Among the various mechanisms by which CD38 antibodies can induce MM cell death is immunomodulation, including multiple pathways for CD38‐mediated T‐cell activation. Patients who respond to anti‐CD38 targeting treatment experience more marked changes in T‐cell expansion, activity, and clonality than nonresponders. Implications Resistance mechanisms that undermine the immunomodulatory effects of CD38‐targeting therapies can be tumor intrinsic, such as the downregulation of CD38 surface expression and expression of complement inhibitor proteins, and immune microenvironment‐related, such as changes to the natural killer (NK) cell numbers and function in the bone marrow niche. There are numerous strategies to overcome this resistance, which include identifying and targeting other therapeutic targets involved in, for example, adenosine production, the activation of NK cells or monocytes through immunomodulatory drugs and their combination with elotuzumab, or with bispecific T‐cell engagers.
