Efficacy, drug survival, safety and metabolic parameters of ixekizumab in patients with moderate-to-severe psoriasis in China: A two-year real-world study

Long-term, real-world studies of the efficacy and metabolic parameters of ixekizumab in difficult-to-treat areas of psoriasis are lacking. A two-year retrospective study was conducted to evaluate the long-term efficacy, safety, drug survival and metabolic parameters of ixekizumab in the real world. A total of 258 patients were enrolled. At 52 weeks, PASI 75/90/100 was achieved in 92.0 %, 79.8 % and 54.6 % of patients, respectively. The efficacy was maintained at week 104 with PASI 75/90/100 of 92.6 %, 81.5 % and 48.1 %, respectively. At week 12, sPGA 0/1 was achieved in 71.0 % of scalp psoriasis, 60.0 % of palmoplantar psoriasis and 68.8 % of genital psoriasis. The probability of drug survival at 12 and 24 months was 67.1 % and 56.3 %, respectively. The most common adverse events included local injection reactions (31.8 %), allergies (11.6 %) and infections (6.1 %). No disease activation was observed in patients with latent tuberculosis or hepatitis B/C. No hyperlipidemia or hyperglycemia was observed. This study confirmed the long-term efficacy, high drug survival and favorable safety of ixekizumab in a real-world setting.
