Company News

Recently, China Medical System’s innovative drug ILUMETRI (Tildrakizumab Injection) has issued its first prescriptions for psoriasis patients who meet the treatment requirements in multiple hospitals located in different Chinese cities, including the Dermatology Hospital of the Chinese Academy of Medical Sciences, the Third Affiliated Hospital of Sun Yat-sen University, the Dermatology Hospital of Southern Medical University, and the First People’s Hospital of Foshan City. With the official launch of ILUMETRI’s nationwide drug supply, ILUMETRI officially stepped into large-scale clinical application, providing better choices for the long-term treatment and disease management among psoriasis patients in China.

On May 26, 2023, ILUMETRI (Tildrakizumab Injection) was approved for marketing by the National Medical Products Administration of China for the treatment of adult patients who have moderate to severe plaque psoriasis and are suitable for systemic therapy or phototherapy. On December 13th, the “National Catalogue of Medicines for Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance (2023) ” was released, and ILUMETRI was successfully included in Class B of the National Medical Insurance Catalogue, further improving its accessibility and affordability.

ILUMETRI is a humanized lgG1/κ monoclonal antibody designed to selectively bind to the p19 subunit of interleukin-23 (IL-23) and inhibit its interaction with the IL-23 receptor. Thereby leading to inhibition of the release of pro-inflammatory cytokines and chemokines. The extended study of ILUMETRI’s Phase III clinical trial in China, demonstrated that the primary efficacy assessment indicator PASI 75 response rate continued to increase over treatment time. The PASI 75 response rate reached a high level after 28 weeks of treatment with ILUMETRI and maintained at 91.3% at week 52, and ILUMETRI showed good long-term safety and tolerance. The maintenance period of ILUMETRI requires only 4 administrations per year, which may lead to higher patient compliance.
