Background Ingenol mebutate (IngMeb) is approved for treatment of actinic keratoses (AK) and may cause unpredictable local skin responses (LSR). Objectives We sought to investigate whether IngMeb-induced LSR, pain, and pruritus could be alleviated with a topical glucocorticoid and, further, to assess efficacy, cosmetic outcome, and patient satisfaction in patients with severe photodamage. Methods In this blinded, randomized controlled clinical trial, patients with multiple AK and field cancerization of the face or scalp were treated in 2 areas with IngMeb (0.015%) daily for 3 days. After finalized IngMeb treatment, 1 area was randomized to receive topical clobetasol propionate (0.05%) twice daily for 4 days. Assessments included LSR (0-24; days 1, 4, 8, 15, 57), pain (0-10) and pruritus (0-3; days 1-15), AK clearance (days 15, 57), and cosmetic outcome (0-3; day 57). Results Clobetasol propionate application had no influence on LSR (P =.939), pain (P =.500), pruritus (P =.312), or AK cure rate (P =.991). Overall, IngMeb cleared 86% of all AK lesions, exerting a therapeutic effect on all AK severity grades; cure rates were 88%, 70%, and 60% for grade I, II, and III AK, respectively. Skin texture improved significantly in remedied areas (2.0 vs 1.0; P <.001); no hypopigmentation, hyperpigmentation, or scarring were observed. Limitations These results do not provide safety and efficacy beyond 2 months of follow-up. Conclusion Application of clobetasol propionate does not alleviate IngMeb-induced LSR after 3 days of IngMeb treatment.
