A significantly greater reduction in mean (SD) PPPASI total score from baseline was observed at week 16 for guselkumab (?10.2 [8.07]) vs placebo (?6.4 [7.55]) (difference in LS mean, ?5.65; 95% CI, ?9.80 to ?1.50; em P /em ?=?.009) (Figure 2B). 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, C2.9 to C0.2; Valuevalues shown are for the least squares mean difference (guselkumab vs placebo) at week 16. C, Percentage of patients achieving proportion of patients with 50% or greater improvement from baseline of PPPASI total score (PPPASI-50) response through week 24 (nonresponder imputation, full analysis set). D, Percentage of patients with physicians global assessment scores of 1 1 or less through week 24 (nonresponder imputation, full analysis set). A significantly greater reduction in mean (SD) PPPASI total score from baseline was observed at week 16 for guselkumab (?10.2 [8.07]) vs placebo (?6.4 [7.55]) (difference in LS mean, ?5.65; 95% CI, ?9.80 to ?1.50; em P /em ?=?.009) (Figure 2B). At week 24, mean (SD) reductions in PPPASI total scores continued to be numerically lower in the guselkumab group (?11.8 [8.99]) vs placebo group (?9.2 [9.72]). At week 16, the proportion of patients achieving PPPASI-50 (LOCF analysis) was significantly higher in the guselkumab group (15 of 25 [60%]) vs placebo group (5 of 24 [21%]) (difference in proportion, 39.2; 95% CI, 14.0-64.3; em P /em ?=?.009). Similarly, a greater proportion of patients receiving guselkumab achieved a PGA score (LOCF analysis) of 0 or 1 (indicating cleared or minimal PPP) at week 16 (6 of 25 [24%]) vs those receiving placebo (2 of 24 [8%]); however, the difference in proportion was not significant (difference in proportion, 15.7; 95% CI, ?4.4 to 35.7; em P /em ?=?.25) (Table 2). Through week 24, a higher proportion of patients in the guselkumab group, as compared with the placebo group, were PPPASI-50 responders (guselkumab, 16 of 25 [64%]; placebo, 8 of 24 [33%]) and had a PGA score of 1 1 or less (guselkumab, 8 of 25 [32%]; placebo, 3 of 24 [13%]) (Figure 2C and D). No patients receiving guselkumab showed worsening of PPP while receiving treatment.
