About this study

Official title: The Influence of BCG Vaccine as a Booster TDaP-IPV Vaccination: an Explorative Study

This study has three purposes:

To investigate whether the immune response to pertussis is increased when TDaP-IPV is given together with BCG vaccine, compared to when it is given alone.

To investigate whether BCG vaccination modulates the immune response to non vaccine target antigens (i.e., antigens/pathogens not used in the vaccine itself).

To investigate whether TDaP-IPV vaccination modulates the immune response to non vaccine target antigens.

Read the detailed description

Rationale: The Bacillus Calmette-Guerin (BCG) vaccine not only protects against Mycobacterium tuberculosis, but has also been shown to reduce morbidity and mortality caused by non-related infections. This effect is likely due to non-specific immunomodulatory effects, at least in part on the innate immune system. Additionally, BCG has been shown to improve immunogenicity of other vaccinations. In contrast, whilst the diphtheria-tetanus-pertussis (DTP) combination vaccine protects against infection with Bordetella pertussis, Clostridium tetani and Corynebacterium diphtheria, it has also been associated with increased mortality due to unrelated infections, particularly in girls in high-mortality countries.

Although widespread DTP vaccination has initially reduced pertussis mortality, the disease has persisted and recently resurged in a number of countries with highly vaccinated populations, including the Netherlands. This has been partially attributed to the switch from a whole-cell vaccine (which is still being used in low-income countries) to a more defined acellular pertussis vaccine, which only protects for a limited period (5-8 years). Strategies to improve the efficacy of pertussis vaccination are therefore urgently required.

As the BCG vaccine has already been used to improve the immunogenicity of other vaccines, the investigators hypothesize that BCG vaccination before or at the same time of DTP vaccination increases the immunogenicity of the DTP vaccine in terms of antibody and T-cell responses to pertussis. Moreover, the investigators aim to assess the effect of DTP vaccination on the known long-term beneficial non-specific effects of BCG on non-mycobacterial infections.

Objective: To examine the effect of BCG as an adjuvant on DTP vaccination, and to investigate the non-specific training effects of BCG and DTP, alone and in combination, on the innate immune system.

Study population: Healthy adult volunteers.

Main study parameters: Comparison of pertussis-specific antibody and T-cell responses, as well as gene transcription between BCG, TDaP-IPV and BCG+TDaP-IPV vaccinated groups. Comparison of cytokine responses to unrelated antigens and/or pathogens before and after BCG, TDaP-IPV or BCG+TDaP-IPV vaccination.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There is no direct benefit to the study participants but these results will potentially lead to novel strategies to optimize vaccinations. The risks for participants are negligible, with the only expected risks being minor side-effects from vaccination and local hematoma forming at the site of venepuncture. This will be minimized by the performance of these procedures by experienced personnel.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Antibody response to TDaP-IPV (time frame: 2 weeks). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02771782, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
