Placebo Controlled Study to Generate Data Characterising Safety Parameters and Immune Responses
Clinical Study to Generate a Set of Data Characterising Clinical Events, Physiological Responses, and Innate and Adaptive Immune Responses Following a Single IM Immunisation With Boostrix® or Placebo in Healthy Adults
The purpose of this protocol is to generate a set of data that will be analysed by integrated systems biology approach, for validation in subsequent clinical trials or in animal models.
240 healthy participants (18-45y) will be enrolled, 200 will be administered a dose of Boostrix on Day 0, 20 will receive a placebo on Day 0.

Detailed Description
This study is part of the BIOVACSAFE project, a 5-year project funded by the Innovative Medicine Initiative, which will undertake a series of correlated clinical studies that will apply and develop technologies to generate clinical data on inflammation with licensed vaccines as benchmarks, and identify biomarkers to predict acceptable reactogenicity, for correlation with standardized clinical readouts and inflammatory markers assessed in natural infections.
The purpose of this protocol is to generate data to undergo integrated systems biology analysis to validate biomarkers identified in the exploratory studies conducted previously or to identify new biomarkers of responses to immunisation
The data set will include data characterising:
Physiological responses at various time points after immunisation by measuring:
- Local and systemic vaccine-related clinical events.
- Haematology (blood counts and ESR) and biochemistry parameters.
Innate and adaptive immune responses including:
- Innate immune activation detected by global gene expression in whole blood
- Adaptive humoral immunity determined by the quantification antibodies directed against Tetanus toxoid (TT), Diphteria toxoid (DT), Pertussis toxin (PT), Fimbrial haemagglutinin (FHA) and Pertactin (PTN).
- Adaptive immune activation detected by gene pathway activation in whole blood
- Metabolic responses as detected by metabolic gene expression and pathway activation in whole blood
- Innate and adaptive immune activation detected by measuring the concentration of selected soluble mediators in serum including: chemokines and cytokines and acute phase proteins
- As an exploratory endpoint, the adaptive cellular immune response will be evaluated via counting vaccine antigen-specific Cluster of Differentiation 4 (CD4)+ T cells expressing activation markers and/or cytokines following in vitro stimulation and analysis by flow cytometry (and or CyTOF).
- Genetic testing of subjects when deemed necessary (genetic testing analysis may be SNP (single nucleotide polymorphism) analysis or full genome analysis).
- Correlations in changes in innate immune activation and metabolism with adverse events, haematology and biochemistry panels, genotype and physiological assessments
The investigators will biobank all samples for the duration of the BIOVACSAFE programme so that they can selectively analyse different samples and different time points depending on the results generated, principally from the gene expression analysis of whole blood.
