IMPORTANCE: Palmoplantar pustulosis (PPP) is a recalcitrant skin disease with no
biologics currently approved for treatment. The involvement of interleukin 23
(IL-23) and cytokines of the type 17 helper T cell lineage in the pathogenesis of
PPP has been recently postulated. OBJECTIVE: To evaluate the efficacy and safety
of guselkumab, an anti-IL-23 monoclonal antibody, in Japanese patients with PPP.
DESIGN, SETTING, AND PARTICIPANTS: This double-blind, randomized,
placebo-controlled, parallel-group, 24-week trial was conducted between May 14,
2013, and September 27, 2014, at 11 centers in Japan. Participants were patients
with moderate to severe PPP that did not respond adequately to conventional
treatments. INTERVENTIONS: Patients were randomized 1:1 to receive guselkumab,
200 mg, by subcutaneous injection or matching placebo at weeks 0 and 4. MAIN
OUTCOMES AND MEASURES: Changes in total scores of skin-related outcomes from
baseline at the end of week 16 (primary clinical cutoff) and through week 24 were
measured. Serum biomarker analyses were performed at baseline, week 4, and week
16, and safety was monitored through week 24. RESULTS: Of 49 randomized patients
(35 [71%] women; median [range] age, 52 [28-77] years), 41 completed the study at
week 24. Mean (SD) PPP severity index total scores (primary end point) improved
significantly from baseline in guselkumab-treated patients (-3.3 [2.43]) vs
placebo (-1.8 [2.09]) (least squares mean difference, -1.5; 95% CI, -2.9 to -0.2;
P?=?.03). At week 16, PPP area and severity index scores (least squares mean
difference, -5.65; 95% CI, -9.80 to -1.50; P?=?.009) and proportion of patients
achieving 50% reduction in these scores (difference in proportion, 39.2; 95% CI,
14.0-64.3; P?=?.009) improved significantly. A numerically higher proportion of
patients had a physician's global assessment score of 1 or less in the guselkumab
group vs placebo. Improvement in efficacy scores was maintained through week 24
in the guselkumab group. Significant reductions from baseline in serum IL-17A and
IL-17F cytokine levels were observed at weeks 4 and 16. Frequency of
treatment-emergent adverse events was comparable between the guselkumab group (19
of 25 patients [76%]) and the placebo group (18 of 24 patients [75%]). Frequent
adverse effects included nasopharyngitis (14 patients [29%]), headache (3
patients [6%]), contact dermatitis (3 patients [6%]), and injection site erythema
(3 patients [6%]). No major safety concerns emerged during the study. CONCLUSIONS
AND RELEVANCE: Targeting IL-23 and its associated immune cascade with guselkumab
may be a safe and useful therapeutic option for treatment of PPP. TRIAL
