Abstract
Whether clinical and genetic markers can be used to differentiate patients with varying responses to different psoriasis therapies needs to be elucidated. Here, we assess whether human leukocyte antigen C (HLA-C)*06:02 is associated with response to biologics. Response to treatment was defined as a Psoriasis Area and Severity Index score of ≤2 (PASI≤ 2) after 3 months. In total, 648 patients with psoriasis initiating treatment with biologics were included; 289 were HLA-C*06:02 positive and 359 were HLA-C*06:02 negative. Patients were treated with tumor necrosis factor (TNF) inhibitors (n = 469), interleukin (IL)-12/23 inhibitors (n = 92), IL-17 inhibitors (n = 78), and IL-23 inhibitors (n = 9). Significantly more patients positive for HLA-C*06:02 achieved PASI≤ 2 compared with patients negative for HLA-C*06:02 when treated with IL-12/23 inhibitors. There was no significant difference between response in HLA-C*06:02 positive and negative patients for TNF inhibitors or IL-17 inhibitors. No analyses were conducted for IL-23 inhibitors because of the limited number of patients. The data confirm that HLA-C*06:02 may be used as a biomarker for response to anti-IL12/23 treatment.
