Conditions

Diphtheria, Tetanus, Pertussis, Poliomyelitis, Hepatitis B, Haemophilus Influenzae Type b Infection

Brief summary

This is a single-center, randomized, active-controlled, parallel-design, double-blind, phase I study to evaluate the safety and immunogenicity of a single dose of APV006 in healthy adults.

Interventions

Hexavalent vaccine (DTaP-HepB-IPV-Hib vaccine: Diphtheria-Tetanus-Acelluar Pertussis-Hepatitis B-Sabin Inactivated Poliovirus-Haemophilus influenzae type b vaccine)

Masking
DOUBLE (Subject, Investigator)

Masking description

The study pharmacist and study staff who administer the investigational vaccine (e.g., medication nurse) will not be blinded in this study since a control vaccine that can be visually distinguished from the study vaccine will be used. The study staff including the investigator will remain blinded, except the unblinded staff.

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
Number of subjects with immediate reactionsFor 30 minutes after the vaccinationImmediate reactions after vaccination with the study vaccine mean all the signs and symptoms occurring within 30 minutes after the vaccination.
Number of subjects with solicited adverse eventsFor 7 days after the vaccination [Day 1-8]Solicited adverse events are classified into the local(pain, tenderness, erythema/redness, induration/swelling, pruritus) and systemic(fever, fatigue, chills/shivering, myalgia, headache, arthralgia, decreased appetite, diarrhea, nausea/vomiting, hypersensitivity) signs and symptoms.
Number of subjects with unsolicited adverse eventsFor 28 days (+7 days of window period) after the vaccination [Day 1-29]Unsolicited adverse events mean all the adverse events excluding the solicited adverse events that occur after the ICF is obtained until 28 days after vaccination.
Number of subjects with serious adverse eventsFor 181 days (+7 days of window period) after the vaccination [Day 1-181]serious adverse events that occur after the ICF is obtained until 6 months after vaccination.

Secondary

MeasureTime frameDescription
Proportion of the subjects who meet one of the following regarding anti-PT, anti-FHA, and anti-PRNDay 29 (+7 days window period)①If the antibody concentration is \< 4 X LLOQ before the administration of the investigational vaccine: The antibody concentration is ≥ 4 X LLOQ 29 days after the administration of the investigational vaccine ②If the antibody concentration is ≥ 4 X LLOQ before the administration of the investigational vaccine: The antibody concentration 29 days after the administration of the investigational vaccine is ≥ the antibody concentration before the administration
GMC or GMT values for each antigen prior to and 28 days post-vaccination with the study vaccine (Day 29)Day 29 (+7 days window period)Immunogenicity of each components (antibodies against Diphtheria, Tetanus, Acelluar Pertussis, Polio, Hepatitis B, and Haemophilus influenzae type b
Proportions of the subjects who meet seroprotection/vaccine-response to each antigen and the subjects who have shown seroconversion 28 days post-vaccination with the study vaccine (Day 29) compared to pre-vaccination.Day 29 (+7 days window period)Immunogenicity of each components (antibodies against Diphtheria, Tetanus, Acellular Pertussis, Polio, Hepatitis B, and Haemophilus influenzae type b)
