Abstract

Importance Psoriasis of the scalp, palms and/or soles, and nails is challenging to treat. Objective To evaluate the effect of guselkumab on psoriasis in specific body regions. Design, Setting, and Participants VOYAGE 1 and VOYAGE 2 were, double-blind, placebo- and adalimumab-controlled studies of guselkumab conducted at 101 and 115 global sites, respectively, from November 3, 2014, to May 19, 2016. Patients had moderate to severe plaque psoriasis (Psoriasis Area and Severity Index score ≥12, Investigator’s Global Assessment [IGA] score ≥3, and ≥10% body surface area with psoriasis). This post hoc data analysis was performed from February 10 through November 15, 2017. Exposures Patients were randomized to guselkumab, 100 mg (weeks 0 and 4, then every 8 weeks); placebo followed by guselkumab, 100 mg, starting at week 16; or adalimumab (80 mg [week 0] and 40 mg [week 1, then every 2 weeks]). Main Outcomes and Measures Efficacy was assessed through week 24. End points included numbers of patients achieving scores of 0 or 1 (clear or near clear) or 0 (clear) on the scalp-specific IGA (ss-IGA), Physician’s Global Assessment of the hands and/or feet (hf-PGA), and fingernail PGA (f-PGA) and percentage of improvement in target Nail Psoriasis Severity Index score. Results Of 1829 randomized patients (mean [SD] age, 43.6 [12.4] years; 1300 [71.1%] male, 1498 [81.9%] white), 1576 (86.2%) had psoriasis of the scalp; 501 (27.4%), palms and/or soles; and 1049 (57.4%), fingernails.

How strong is the evidence?

Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 1,829 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
