Objectives of Study:

Main objectives: 1. Immunogenicity: (1) To demonstrate that the immunogenicity of 5 doses of experimental vaccine (freeze-dried human rabies vaccine (MRC-5 cells)) or 5 doses of control vaccine (freeze-dried human rabies vaccine (human diploid cells)) was not inferior to that of 5 doses of control vaccine 14 days after the first dose. (2) To demonstrate that the immunogenicity of the 4-dose test vaccine or the 5-dose control vaccine was not inferior to that of the 5-dose control vaccine 14 days after the first dose in a population aged 10-60 years. (3) It was demonstrated that the antibody positive conversion rate reached 100% in 14 days after full inoculation of the experimental vaccine with 5 doses or 4 doses in the population aged 10-60 years. Antibody positive conversion rate: the percentage of persons with rabies virus neutralizing antibody < 0.5IU/ml before immunization and ≥0.5IU/ml after immunization. 2. Safety: (1) To evaluate the safety of the trial vaccine administered in people aged 10-60 years compared with the control vaccine. Secondary objectives: 1. Vaccination stages: (1) To compare the immunogenicity of the trial vaccine, the 5-dose program, and the 4-dose program in a population aged 10-60 years. 2. Observation order of immune persistence: (1) The immunogenicity of the 5-dose test group, the 4-dose test group and the 5-dose control group was compared 3 months after full vaccination in the 10-60 year old population, so as to evaluate the immune persistence 3 months after the trial vaccine. (2) The immunogenicity of the 5-dose trial group and the 4-dose trial group was compared at 12 months after full vaccination in the 10-60 year old population to evaluate the immune persistence at 12 months after full vaccination.

随机方法(请说明由何人用什么方法产生随机序列):

第一阶段:开放性设计,18-60岁年龄组40例入组受试者随机按照5剂或者4剂程序接种疫苗,5剂和4剂程序组各接种20例,疫苗编号为A001-A040。10-17岁年龄组40名入组受试者随机按照5剂或者4剂程序接种疫苗,5剂和4剂程序组各接种20人,疫苗编号为A041-A080。 第二阶段:统计师应用SAS统计软件(版本为9.4),以区组随机化方法将1800个编号进行随机化,受试者按1:1:1分为4剂试验组、5剂试验组和5剂对照组,疫苗编号为:0001-1800。

Randomization Procedure (please state who generates the random number sequence and by what method):

Phase I: Open design, 40 enrolled subjects in the age group of 18-60 years old were randomly inoculated with the vaccine according to the 5-dose or 4-dose program, 20 cases in each of the 5-dose and 4-dose program groups, and the vaccine number was A001-A040. Forty enrolled subjects in the 10-17

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

第一阶段:采用开放性设计,不进行疫苗编盲。 第二阶段:采用盲法设计,由随机化统计师与其他编盲人员进行疫苗编盲,即按照盲底将打印好的疫苗标签粘贴于每份疫苗指定位置,疫苗编号同研究编号。由随机化统计师督导疫苗编盲,指导编盲操作人员按照盲底进行贴签。完成编盲后,盲底应由编盲人员封存。整个编盲过程须有文字记录。编盲人员不得参加本临床试验的其他相关工作,同时也不得向参加本临床试验工作的任何人员泄露盲底。 第二阶段仅对5剂程序组设盲。本次试验采用国内批准上市的同类疫苗作为阳性对照,由于试验疫苗的稀释剂包装瓶与对照疫苗稀释剂包装瓶不一致,包装编盲后,每个盒子用封口签封住,不得随意拆启。试验过程中采取如下措施进行盲态维持,以尽量减少偏倚:(1)疫苗接种人员为专人专岗,不得参与本试验中的其他工作。接种人员和疫苗管理员需签署保密协议,承诺不得向其他人员(包括其他研究者及受试者)透露任何可能造成盲底泄露的信息;(2)接种人员接种时如果发现封口签拆开了,则视为该受试者破盲;接种人员不得在受试者面前打开疫苗外包装或进行疫苗配置;(3)使用过的疫苗(包括稀释液)的空瓶/空盒由接种人员复原至原包装盒内,贴上封口签封存,当天工作完成后需及时清点并移交至疫苗管理员处封存。待现场关闭申办方授权后,由研究现场统一移交申办方做销毁处理且保留销毁记录。

Blinding:

Phase 1: Adopting an open design without blinding the vaccine. Phase 2: Blind design is adopted, with randomized statisticians and other blinding personnel conducting vaccine blinding. The printed vaccine labels are pasted at the designated positions of each vaccine according to the blinding background, and the vaccine number is the same as the study number. Randomized statisticians supervise vaccine blinding and guide blinding operators to label according to the blind background. After completing the blinding process, the blind background should be sealed by the blinding personnel. The entire process of blinding must be documented in writing. Blinding personnel are not allowed to participate in other related work of this clinical trial, and are also not allowed to disclose blinding information to anyone participating in this clinical trial. In the second stage, only the 5-dose program group was blinded. This experiment used domestically approved vaccines of the same type as the positive control. Due to the inconsistency between the diluent packaging bottle of the experimental vaccine and the diluent packaging bottle of the control vaccine, after blinding the packaging, each box was sealed with a sealing label and cannot be opened arbitrarily. During the experiment, the following measures were taken to maintain blindness and minimize bias: (1) Vaccine recipients were assigned to specialized positions and were not allowed to participate in other work in this experiment. Vaccination personnel and vaccine administrators need to sign a confidentiality agreement, promising not to disclose any information that may cause blind base leakage to other personnel (including other researchers and subjects); (2) If the vaccination personnel find that the sealing label has been opened during vaccination, it is considered that the subject has broken the blind; Vaccination personnel are not allowed to open the vaccine packaging or prepare the vaccine in front of the subjects; (3) The empty bottles/boxes of used vaccines (including diluents) shall be restored to their original packaging by the vaccination personnel, sealed with sealing labels, and promptly counted and handed over to the vaccine administrator for sealing after the work is completed on the same day. After the on-site closure of the applicant's authorization, the research site will uniformly transfer it to the applicant for destruction processing and retain the destruction record.
