ABSTRACT
BackgroundBiologic agents offer a range of new therapeutic options for patients with psoriasis; however, the relative benefit–risk profiles of such therapies are not well known. We comparedtwo biologic agents, ustekinumab (an interleukin-12 and interleukin-23 blocker) and etanercept (an inhibitor of tumor necrosis factor ), for the treatment of psoriasis.Methods We randomly assigned 903 patients with moderate-to-severe psoriasis to receive subcutaneous injections of either 45 or 90 mg of ustekinumab (at weeks 0 and 4) or high-doseetanercept (50 mg twice weekly for 12 weeks). The primary end point was the proportion of patients with at least 75% improvement in the psoriasis area-and-severity index (PASI)at week 12; a secondary end point was the proportion with cleared or minimal disease on the basis of the physician's global assessment. Assessors were unaware of thetreatment assignments. The efficacy and safety of a crossover from etanercept to ustekinumab were evaluated after week 12.
Results There was at least 75% improvement in the PASI atweek 12 in 67.5% of patients who received 45 mg of ustekinumab and 73.8% of patients who received 90 mg, as compared with 56.8% of those who received etanercept (P=0.01 and P
