Plaque psoriasis is a chronic, autoimmune, inflammatory skin disease associated with significant morbidity and reduced quality of life. In China, the prevalence of plaque psoriasis increased four-fold between 1987 and 2012. Adalimumab is a biologic antibody used to treat plaque psoriasis globally. However, high treatment costs remain as a significant barrier to adalimumab therapy. Therefore, HLX03 has been developed as an adalimumab (Humira®) biosimilar, which is almost identical to the licensed reference adalimumab, but less expensive and more accessible to patients. In this randomized clinical trial, the efficacy (ability of a drug to produce the desired treatment effects), safety, and immunogenicity (ability of a drug to induce immune response which would affect its efficacy and safety) of HLX03 were compared with the reference adalimumab in Chinese patients with moderate-to-severe plaque psoriasis. Efficacy was evaluated by comparing the changes in severity and extent of disease using Psoriasis Area and Severity Index score between treatment initiation and week 16. Safety was monitored by adverse events, laboratory tests and vital signs. Immunogenicity was assessed by the incidence of antidrug antibodies. Among the 262 randomized patients, 131 received HLX03 and 130 received adalimumab. Both groups reported similar improvements in Psoriasis Area and Severity Index scores (between-group difference fell within the prespecified equivalence margins), and also in other efficacy evaluations. Additionally, the two treatment groups showed similar safety and immunogenicity profiles. In summary, HLX03 demonstrated equivalent efficacy to adalimumab, validating it as an alternative treatment for patients with plaque psoriasis in China.
