About Product

Tildrakizumab is a humanized lgG1/k monoclonal antibody designed to selectively bind to the p19 subunit of IL-23 and inhibit its interaction with the IL-23 receptor, leading to inhibition of the release
of pro-inflammatory cytokines and chemokines. Currently, the product has been approved for marketing in the U.S. under the brand name of ILUMYATM, for treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy, and also been approved for commercialization in Europe, Australia and Japan.

There are more than 6.5 million people suffering from psoriasis in China with an incidence rate of 0.47%. About 30% of patients are with moderate-to-severe psoriasis; among them, nearly 62% are dissatisfied with existing treatment options. The most common form, affecting about 90 percent of people living with psoriasis, is plaque psoriasis. Tildrakizumab is expected to be a safe, effective and the most cost-effective innovative monoclonal antibody targeting IL-23, benefiting more patients and their families in China.
