EADV 2019
There is a high need for oral treatments for atopic dermatitis (AD) that cannot be controlled with local therapy. Both phosphodiesterase (PDE) inhibitors and Janus kinase (JAK) inhibitors are interesting approaches [1]. PDE4 is involved in the regulation of pro-inflammatory cytokines via the degradation of cyclic adenosine monophosphate. Targeting PDE4 reduces the production of pro-inflammatory mediators in AD and may be an interesting treatment target with a favourable safety profile [2]. Apremilast, an orally available PDE4 inhibitor, is approved for the treatment of adults with moderate-to-severe psoriasis and active psoriatic arthritis. This immune modulator regulates a number of the pro-inflammatory signals involved in AD, including IL-17, IL-22, IL-13, and IL-31 [3]. A phase 2 study published earlier this year evaluated the treatment effect of 30 mg and 40 mg of apremilast on skin clearance, assessed in EASI percentage change from baseline in ...
