Abstract
P>Background Data are lacking on the use of topical therapies in combination with tumour necrosis factor blockers for the treatment of psoriasis. Objectives To assess the efficacy and safety of adalimumab (ADA) with topical calcipotriol/betamethasone (C/B) in patients with psoriasis resembling those treated in routine clinical practice. Methods A 16-week, randomized, vehicle-controlled trial was conducted in patients with moderate to severe psoriasis and previous failure, intolerance or contraindications to two or more systemic treatments. All patients received ADA (80 mg, week 0; 40 mg every other week, weeks 1-15) in addition to either topical C/B or drug-free vehicle applied once daily for 4 weeks, and as needed thereafter. The primary endpoint was 75% improvement from baseline in Psoriasis Area and Severity Index (PASI 75) at week 16. Results A total of 730 patients received either ADA + C/B (n = 366) or ADA + vehicle (n = 364). PASI 75 response was initially higher with the combination therapy [14 center dot 8% for ADA + C/B vs. 5 center dot 8% for ADA + vehicle at week 2 (P < 0 center dot 001); and 40 center dot 7% vs. 32 center dot 4%, respectively, at week 4 (P = 0 center dot 021)]. After week 4, the trend was towards a higher response with ADA monotherapy, with no statistical difference in the PASI 75 response at week 16 (64 center dot 8% for ADA + C/B vs. 70 center dot 9% for ADA monotherapy, P = 0 center dot 086). Safety findings were consistent with previous ADA trials. Conclusions ADA + C/B resulted in more rapid and higher efficacy within the first 4 weeks; thereafter, the trend was towards a higher response with ADA monotherapy. There was no statistical difference in the PASI 75 response at week 16. Both treatment regimens were well tolerated.
