Abstract
BACKGROUND: Ixekizumab, an anti-IL-17A monoclonal antibody, demonstrated a high level of efficacy in moderate-to-severe plaque psoriasis (PP) patients. OBJECTIVE: To evaluate the efficacy and safety of open-label ixekizumab in Japanese patients with moderate-to-severe PP, erythrodermic psoriasis (EP) and generalized pustular psoriasis (GPP). METHODS: Patients received 160-mg subcutaneous ixekizumab injection at Week 0, 80-mg every 2 weeks through Week 12 and 80-mg every 4 weeks through Week 24. Efficacy and safety are reported through 24 weeks; additional safety data are available for some patients. RESULTS: A total of 78 patients with PP, 8 with EP and 5 with GPP enrolled. In PP patients, PASI75 and PASI90 response rates were 98.7% (77/78) and 83.3% (65/78) at Week 12 respectively. In EP patients, PASI75 and PASI90 were 100.0% (8/8) and 62.5% (5/8) and in GPP patients were 80.0% (4/5) and 60.0% (3/5). Overall, 84.0% (76/91) had a treatment-emergent AE through ≥24 weeks. There were no serious AEs, deaths, cases of tuberculosis or invasive fungal infections. LIMITATIONS: No control group and small sample sizes, especially for EP and GPP. CONCLUSION: By Week 12, nearly all patients with PP, EP and GPP achieved PASI75. The safety profile was consistent with reported results and no unexpected safety signals were observed.
