Completion Of The first batch of subject enrollment in the Phase I clinical trial of the new adjuvant recombinant herpes zoster vaccine in China


Jiangsu Recbio Technology Co., Ltd. ("Recbio" , HKEX:02179) is pleased to announce that the Group has recently completed the first batch of subject enrollment in the Phase I clinical trial of the new adjuvant recombinant herpes zoster vaccine REC610 in China.The study is a randomized, observer-blinded, GSK Shingrix® active-controlled phase I clinical trial and recruited 180 healthy adults aged 40 and above in Pu'er City, Yunnan Province to evaluate the safety, tolerability, and immunogenicity of REC610.



At the kick-off meeting of the REC610 Phase I clinical trial project held by the Center for Disease Control and Prevention in Pu'er City, Yunnan Province, researchers introduced the disease background, REC610 product information, and provided a detailed introduction to the overall design, trial process, and precautions of the clinical trial. After the meeting, the research team sorted out the experimental process to support the smooth progress of subsequent experiments.



REC610 is equipped with a novel adjuvant BFA01 independently developed by the Company, which can promote the production of high levels of VZV glycoprotein E (gE)-specific CD4+ T cells and antibody. REC610 is intended to prevent shingles in adults aged 40 and above. Previously, the Company conducted a GSK Shingrix® active-controlled FIH clinical trial of REC610 in the Philippines. The Interim Analysis (IA) results showed that REC610 demonstrated overall favorable safety and tolerability profile in healthy participants aged 40 and above after two doses of the vaccination. REC610 induced strong gE-specific humoral and cellular immune responses, which were evident after the first vaccination and reached the peak at 30 days after the second vaccination. The humoral and cellular immune responses were comparable between REC610 and Shingrix® group, and the immune response level in REC610 group was numerically higher than that in Shingrix® group.
