IntroductionPalmoplantar involvement in patients with psoriasis can severely impact quality of life and limit work productivity. Topical treatments generally have limited efficacy for moderate‐to‐severe palmoplantar psoriasis. Systemic treatments such as methotrexate, acitretin, tumour necrosis factor alpha (TNF‐α) inhibitors (etanercept, adalimumab and infliximab) and interleukin 17A or 12/23 inhibitors (secukinumab and ustekinumab) have been reported to be efficacious. However, their efficacy in palmoplantar psoriasis is usually lower than when they are used for psoriasis vulgaris. Only 30–40% of patients with moderate‐to‐severe palmoplantar psoriasis achieve a Palmoplantar Psoriasis Physician Global Assessment (PPPGA) of 0/1 after 12–16 weeks of treatment with biologics. There is a need for the development of novel treatments for palmoplantar psoriasis.Apremilast is an oral phosphodiesterase inhibitor, that is approved for the treatment of psoriasis and psoriatic arthritis. A post hoc analysis of palmoplantar data from three phase 2 and 3 studies conducted in patients with moderate‐to‐severe psoriasis vulgaris suggested that apremilast could be effective for the treatment of psoriasis involving palms and soles. However, this analysis included all patients presenting at least a moderate severity based on physician global assessment of palmoplantar disease regardless of the surface area involved with palmoplantar psoriasis at baseline. This study evaluates the efficacy
