Pharmacology
Crisaborole is a phosphodiesterase 4 (PDE-4) inhibitor; PDE-4 inhibition results in increased intracellular cyclic adenosine monophosphate (cAMP) levels, though the specific mechanism by which it treats atopic dermatitis is not well defined.
Lebrikizumab-lbkz is an IgG4 monoclonal antibody that binds with high affinity to IL-13, inhibiting IL-13 signaling through the IL-4Ra/IL-13Ra1 receptor complex; IL-13 is a cytokine central to Type 2 inflammation in atopic dermatitis pathogenesis.
