CSPC Pharmaceutical Group Limited (01093) has announced that Phase I/II clinical trials for SYS6052, a recombinant herpes zoster virus vaccine (Chinese Hamster Ovary (CHO) cells) developed by the company, have officially commenced in China.
The product is a recombinant protein vaccine developed by the group, composed of the varicella-zoster virus glycoprotein E (gE) protein antigen and a novel nano-adjuvant system independently developed by CSPC Pharma. By optimizing the antigen and nano-adjuvant system, the product is designed to induce strong humoral and cellular immune responses.
The company received the Drug Clinical Trial Approval Notice issued by the National Medical Products Administration of the People's Republic of China in July 2026, and subsequently launched a randomized, blinded, controlled Phase I/II clinical trial aimed at evaluating the safety and immunogenicity of the product in individuals aged 40 and above.
Currently, participant recruitment and screening for the clinical trial are being actively advanced.
