Study summary

The purpose of this study was to assess the safety and immunogenicity of GSK's combined diphtheria, tetanus, acellular pertussis, hepatitis B, inactivated poliovirus and Haemophilus influenzae type b conjugate vaccine (DTPa-HBV-IPV/Hib) versus MCM Vaccine BV's DTaP5-HBV-IPV-Hib vaccine administered to healthy infants and toddlers, between 6 and 12 weeks of age at the time of first vaccination, based on a 2-, 4-, and 12-months of age vaccination schedule.

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

  • Subjects' parent(s)/Legally Acceptable Representative(s) (LAR[s]) who, in the opinion of the investigator, could and would comply with the requirements of the protocol (e.g., return for follow-up visits).
  • Written or witnessed/thumb printed obtained from the parent(s)/LAR(s) of the subject prior to performing any study specific procedure.
  • A male or female child between and including 6 and 12 weeks of age (42 to 84 days) at the time of the first vaccination.
  • Subject born after at least 37 weeks of gestation.
  • Healthy subjects as established by the investigator based on medical history and the clinical examination before entering into the study.

Exclusion criteria

Exclusion Criteria:

  • Any clinical condition that, in the opinion of the investigator, might pose any risk to the subject due to participation in the study. As with other vaccines, administration of DTPa--IPV/Hib should be postponed in subjects suffering from acute severe febrile illness. The presence of a minor infection is not a .
  • Known history of diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Hib diseases since birth.
  • History of any reaction or likely to be caused or exacerbated by any or active component of the vaccine(s).
  • Any confirmed or suspected or immunodeficient condition, including , based on medical history and physical examination (no laboratory testing required).
  • Family history of congenital or hereditary immunodeficiency.
  • Major congenital defects, as assessed by the investigator.
  • Acute or chronic pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined via medical history including physical examination.
  • Medical history of neurological disorder, including seizures.
  • Previous vaccination for diphtheria, tetanus, pertussis, HBV, poliomyelitis, Hib diseases and previous vaccination against pneumococcal infection with pneumococcal conjugate vaccine, with the exception of a birth dose of HBV vaccine, which may have been given in accordance with local recommendations.
  • Use of any or non-registered product (drug, vaccine, or medical device) other than the study vaccine(s) during the period starting 30 days before the first dose of study vaccine(s) (Day -29 to Day 1), or planned use during the study period.
  • Planned administration/administration of a vaccine not foreseen by the study protocol in the period starting 30 days before the first dose and ending 30 days after the last dose of vaccine(s) with the exception of administration of vaccines given as part of the national immunization schedule and as part of routine vaccination practice, e.g., rotavirus vaccine, that were allowed at any time during the study period. In case emergency mass vaccination for an unforeseen public health threat (e.g., a pandemic) would have been organized by public health authorities outside the routine immunization program, the time period described above could be reduced if necessary for that mass vaccination vaccine, provided this vaccine/product(s) is licensed and used according to its Product Information.
  • Administration of long-acting immune-modifying drugs in the period starting 30 days before the first dose and at any time during the study period.
  • Administration of immunoglobulins and/or any blood products or plasma derivatives from birth or planned administration during the study period.
  • Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period starting 3 months prior to the first vaccine. For , this would mean prednisone ≥0.5 mg/kg/day (for paediatric subjects), or equivalent. Inhaled and topical steroids are allowed.
  • Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or would have been exposed to an investigational or a non-investigational vaccine/product (drug or medical device).
  • Child in care.
Terms in these criteria, in plain language(10)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

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.

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Individual participant data

Plan to share: Yes — GSK will assess requests from qualified researchers for anonymized individual patient-level data (IPD) and related study documents. Data sharing is subject to certain criteria, conditions, and exceptions. For further information, refer to https://www.gsk-studyregister.com/About_GSK_Patient_Level_Data_Sharing_Final_13July2023.pdf

Supporting information: Study protocol, Statistical analysis plan, Informed consent form, Clinical study report

Time frame: Anonymized IPD is made available within 6 months of publication of primary, key secondary and safety results for studies in product with approved indication(s) or terminated asset(s) across all indications.

Access criteria: Anonymized IPD is shared with researchers whose proposals are approved by an Independent Review Panel and after a Data Sharing Agreement is in place. Access is provided for an initial period of 12 months but an extension may be granted, when justified, for up to 6 months.
