A Phase I Clinical Trial of Absorbed Acellular Pertussis (Two-Component) Diphtheria-Tetanus Combined Vaccine (For Adults and Adolescents)

the safety and tolerability of different dosages of adsorbed acellular pertussis (two-component) diphtheria-tetanus combined vaccine

Phase I/II Clinical Trial of Diphtheria-Tetanus-Pertussis (Reduced Dose) Vaccine

This is a randomized, double-blinded, parallel-controlled phase I/II clinical trial to evaluate the safety and preliminary immunogenicity of the Tetanus, Diphtheria and Acellular Component Pertussis Vaccine Adsorbed (reduced antigen content) in subjects aged 6 years and above.

A Phase 3 Study of BIBP Diphtheria, Tetanus and Acellular Pertussis (Three Components) Combined Vaccine, Adsorbed

The study will evaluate the safety, immunogenicity，immune persistence and lot-to-lot consistency of Diphtheria,Tetanus and Acellular Pertussis (Three Components) Combined Vaccine, Adsorbed, (DTacP) including 2 parts: PART 1 will evaluate the safety and immunogenicity of DTacP in health infants aged 2 months and 3 months compared with an adsorption Tetanus-diphtheria-acellular Pertussis (DTaP) Vaccine and Diphtheria,tetanus,pertussis(acellular,component),poliomyelitis(inactivated) vaccine(absorbed) and Haemophilus influenzae type b conjugate vaccine (PENTAXIM)，compare the safety and immunogenicity of DTacP with different immunization schedules, and observe the immune persistence. PART 2 will evaluate the lot-to-lot consistency of DTacP in health infants aged 3 months with the 3-dose schedule of 3-4-5 month.

A Phase II/III Study to Evaluate the Immunogenicity, Safety and Lot-to-lot Consistency of LBVD, a Fully Liquid Hexavalent Diphtheria-tetanus-whole Cell Pertussis-hepatitis B-poliovirus-Haemophilus Influenzae Type b Conjugate (DTwP-HepB-IPV-Hib) Vaccine, in Healthy Infants as Primary Series

The purpose of this study is to evaluate immunogenicity, safety and lot-to-lot consistency of LBVD in comparison to co-administration of Pentavalent vaccine and Poliomyelitis Vaccine (Inactivated) in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants

A Clinical Trial of Adsorbed Cell-free DPT Vaccine (5-component) (for People Aged 6 Years and Above)

Pertussis is an acute respiratory infectious disease caused by Bordetella pertussis, diphtheria is an acute upper respiratory infectious disease caused by Gram-positive Corynebacterium diphtheriae, and tetanus is a highly fatal disease caused by Clostridium tetani infection. Currently, there is no clinical trial registration of Diphtheria, tetanus, and pertussis (DPT) vaccine applicable to ≥6 years of age in China, therefore, the five-component acellular DPT combination vaccine developed by our research has a promising future.

A Clinical Trials of Adsorbed Cell-free DPT Vaccine (Five-component)

This is a randomized, blinded, controlled phase II and III clinical trial evaluating the immunogenicity and safety of adsorbed cell-free DPT vaccine. 320 subjects aged 7 years and older in the phase II were divided into two age groups, the ≥18 years group and the 7-17 years group, and randomized 3:1 to receive the trial vaccine Tdcp versus the control vaccine PPV23. 1500 subjects in the phase III were divided into 3 age subgroups. 780 subjects were planned to be enrolled in the 6-year-old group and randomized 1:1 to receive the experimental vaccine Tdcp versus the control vaccine DTaP, and 360 subjects were planned to be enrolled in each of the 7-17 and ≥18 age groups and randomized 3:1 to receive the experimental vaccine Tdcp versus the control vaccine PPV23.

Study to Evaluate the Immunogenicity of LR20062 Compared to Control When Administered Intramuscularly in Healthy Infants At 2, 4, 6 Months of Age

This is a phase II, randomized, double-blind, active-controlled, parallel-group, multicenter study to evaluate the immunogenicity and safety of DTaP-HepB-IPV-Hib hexavalent vaccine LR20062 in healthy infants as primary series at 2, 4, 6 months of age.

Safety and Immunogenicity of DTaP-IPV/Hib Pentavalent Vaccine in Chinese 2-month-old Infants

The main purpose of this study is to evaluate immune persistence at 30 and 36 Months of Age and Pertussis Breakthrough Infections between 19 and 36 Months of Age following two regiments of DTaP-IPV/Hib Pentavalent Vaccine in Healthy 2-Month-Old Infants and Children in China.

Phase I Clinical Trial of Diphtheria-Tetanus-acellular Pertussis Component Combined Vaccine

This study is a randomized, blinded, active-controlled phase I clinical trial to evaluate the safety and preliminary immunogenicity of the Diphtheria-Tetanus-acellular Pertussis Component Combined Vaccine (DTacP) in subjects (aged 2 months to 6 years). Primary safety endpoints are the occurrence of solicited adverse events within 30 minutes after each dose, the occurrence of solicited adverse events within 7 days after each dose, the occurrence of unsolicited adverse events within 30 days after each dose, and the occurrence of adverse events 30 days after immunization. The secondary safety endpoint is the occurrence of serious adverse events (SAEs) within 12 months after immunization. Secondary immunogenicity endpoints are the geometric mean concentration (GMC), geometric mean fold increase (GMFI), seropositive rates, seroconversion rates, or 4-fold increase rates of anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies 30 days after immunization. The exploratory endpoints are the GMC, GMFI, seropositive rates, seroconversion rates, or 4-fold increase rates of anti-DT, anti-PT, and anti-FHA neutralizing antibodies 30 days after immunization in all groups, the GMC and seropositive rates of anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies 12 months after primary immunization in the infant group, the seropositive rates and geometric mean tie (GMT) of anti- type I, type II, type III poliovirus neutralizing antibodies 30 days after immunization in all groups, the seropositive rates and geometric mean tie (GMT) of anti- type I, type II, type III poliovirus neutralizing antibodies 12 months after primary immunization in the infant group.
