Yes

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Healthy male and female adults aged 19 - 55 on Visit 1
  • Those without abnormalities on the screening test on Visit 1
  • Those with a confirmed of 18.5 kg/m2 to less than 30 kg/m2 on Visit 1
  • Those who have heard a detailed explanation of the study and whose written consent to participate in the study was given voluntarily by themselves or their legal representatives

Exclusion criteria

Exclusion Criteria:

  • Those who participated in other studies and took products/ investigational vaccines within 6 months from Visit 1
  • Those who took tetanus toxoid (TT), tetanus-diphtheria (Td), tetanus-reduced diphtheria-acellular pertussis (Tdap) vaccine for adults, or other vaccines containing tetanus-diphtheria for adults within 5 years from Visit 1
  • Those who were vaccinated within 4 weeks from Visit 1 or who plan to receive vaccines other than the investigational vaccine from the participation in this study to Visit 5
  • Have had diphtheria, tetanus, pertussis, , polio, or invasive diseases caused by Haemophilus influenzae type b
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

What researchers measure

Primary outcomes

  1. Number of subjects with immediate reactions

    Immediate reactions after vaccination with the study vaccine mean all the signs and symptoms occurring within 30 minutes after the vaccination.

    Time frame: For 30 minutes after the vaccination

  2. Number of subjects with solicited adverse events

    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.

    Time frame: For 7 days after the vaccination [Day 1-8]

  3. Number of subjects with unsolicited adverse events

    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.

    Time frame: For 28 days (+7 days of window period) after the vaccination [Day 1-29]

  4. Number of subjects with serious adverse events

    serious adverse events that occur after the ICF is obtained until 6 months after vaccination.

    Time frame: For 181 days (+7 days of window period) after the vaccination [Day 1-181]

Secondary outcomes

  1. 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.

    Immunogenicity of each components (antibodies against Diphtheria, Tetanus, Acellular Pertussis, Polio, Hepatitis B, and Haemophilus influenzae type b)

    Time frame: Day 29 (+7 days window period)

  2. Proportion of the subjects who meet one of the following regarding anti-PT, anti-FHA, and anti-PRN

    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

    Time frame: Day 29 (+7 days window period)

  3. GMC or GMT values for each antigen prior to and 28 days post-vaccination with the study vaccine (Day 29)

    Immunogenicity of each components (antibodies against Diphtheria, Tetanus, Acelluar Pertussis, Polio, Hepatitis B, and Haemophilus influenzae type b

    Time frame: Day 29 (+7 days window period)
