Efficacy
IXE-treated patients rapidly achieved and sustained improvements in scalp, nail, and palmoplantar psoriasis for up to 5 years (Figure 1, Figure 2). A large percentage of patients achieved complete clearance at year 5: observed (scalp, 82%; nail, 73%; palmoplantar, 96%) and mNRI (scalp, 77%; nail, 67%; palmoplantar, 85%) (Figure 1). The mean change from baseline (observed and LOCF) was maintained from week 12 through week 264 for patients with scalp and palmoplantar psoriasis and weeks 36 through 264 for patients with nail psoriasis (Figure 2). High percentages of patients (observed or LOCF) with baseline scalp (94%, 95%), nail (73%, 72%), and palmoplantar (98%, 98%) psoriasis showed improvement at week 24, as measured by the
