TAIZHOU, China, March 21, 2024 /PRNewswire/ — Innovative vaccine company Recbio (02179.HK) announced its latest progress and annual results for 2023. The company always adhered to the mission of ” Protect Human Health With Best-In-Class Vaccines”, and achieved the following milestones and progress in research pipeline and business operations.


REC603-Recombinant HPV 9-valent Vaccine

  • We are in the process of conducting phase III clinical trial of REC603 in China and follow-up is being conducted in accordance with the clinical protocol. We have completed the 24th month follow-up visit and are conducting the 30th month follow-up visit observation. We plan to take the pathological endpoint for interim analysis and submit BLA application after meeting the conditions.
  • The “Technical Guidelines for the Clinical Trials of Human Papillomavirus Vaccines (for Trial Implementation)” issued by the Center for Drug Evaluation of NMPA clearly states that “randomized, double-blind, placebo-controlled design is currently the best strategy to confirm the protective efficacy of first-generation vaccines”. Our phase III clinical protocol for the 9-valent HPV vaccine strictly follows the guidelines of the regulatory authorities; and we have the largest HPV 9-valent phase III clinical trial subjects in China and are conducting clinical trials in Henan, Shanxi and Yunnan provinces with high HPV infection rates. Currently, the Company is conducting follow-up visits according to the established protocol, maintaining ranking among the leading group in China in term of the clinical development progress.
  • We are actively promoting the commercialization of recombinant HPV 9-valent vaccine REC603 in overseas markets. In January 2024, we have signed the framework agreement with SPIMACO, a pharmaceutical company in Saudi Arabia, for the recombinant HPV 9-valent vaccine REC603 and entered into an authorization and strategic cooperation. According to the agreement, we exclusively license SPIMACO to develop, register and commercialize recombinant HPV 9-valent vaccine REC603, in 15 Middle East and North Africa countries, including Saudi Arabia. In addition, we have successively achieved intention of cooperation with partners in the United Arab Emirates, the Philippines and India on the recombinant HPV 9-valent vaccine to jointly promote clinical registration and market expansion.

REC610 – Novel Adjuvanted Recombinant Shingles Vaccine

  • We have completed enrollment of all subjects in the phase I clinical trial in China. The study proposes to adopt a randomized, double-blind, parallel controlled design for enrolled 180 healthy adult subjects aged 40 and above in Pu’er, Yunnan Province to evaluate the safety, tolerability and immunogenicity of REC610. REC610 has obtained the Notice on Drug Clinical Trial Approval (notice number: 2023LP02151) issued by the NMPA in October 2023, which is authorized to carry out phase I and phase III clinical trials in China as a Category 3.3 biological product for preventive use.
  • Positive results from the first-in-human (“FIH”) clinical trial interim analysis in the Philippines. Previously, the Company’s REC610 commenced the FIH clinical trial with GSK Shingrix® active controlled 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.

REC625–Novel Adjuvanted Recombinant Respiratory Syncytial Virus Vaccine

  • The REC625 is equipped with the novel adjuvant BFA01 independently developed by us and intended to prevent the diseases caused by respiratory syncytial virus infection in the elderly population. Preclinical studies have shown that REC625 has favorable immunogenicity and can induce high levels of specific neutralizing antibodies, and its immunogenicity is comparable to that of international mainstream varieties.
  • The project adopted our independently designed vaccine antigen structure and relevant invention patents application has been submitted.
  • We plan to complete the preclinical studies of this project in 2024.


  • The two independently developed novel adjuvants, BFA01 and BFA03, have been successfully included in the adjuvant supply pool managed by the Coalition for Epidemic Preparedness Innovations (“CEPI”) due to their significant advantages in efficacy and safety, as well as their commercial-scale industrialization capabilities, to meet the demand for innovative adjuvants from vaccine developers around the world.
  • We actively promote the cooperation of adjuvant empowerment and work with partners to achieve the upgrade and iteration of vaccines, and will share the incremental value of innovative varieties in the future. We have successively signed joint development agreements with two industry chain partners to provide innovative adjuvants and related technical services to jointly develop novel adjuvant respiratory syncytial virus vaccine and novel adjuvant rabies vaccine.


Cash and bank balances

  • Cash and cash equivalents were approximately RMB 912 million as of December 31, 2023, compared to RMB 1.325 billion as of December 31, 2022.

R&D and administrative expenses

  • Operating expenses (R&D and administrative expenses) in 2023 were RMB 631 million .Compared to 2022, the reduction was approximately 27.55%.

Loss for the year

  • The loss for the year was approximately RMB 572 million, narrowed by 22.22% year-on-year
