Clinical Trial Summary

The Healthy Human Global Project-Hong Kong aims to elucidate the heritable and non-heritable factors that drive immunological variance within a healthy population in Hong Kong. By gaining a deeper understanding of these parameters, a path can be paved for personalised and precision medicine, tailored for an Asian population.


Description:

The Healthy Human Global Project-Hong Kong (HHGP-Hong Kong) is built upon the Milieu Intérieur Consortium, a population-based study coordinated by the Institut Pasteur in Paris since 2011 (ClinicalTrials.gov study numbers NCT01699893 and NCT03905993). The Milieu Intérieur comprised of 1,000 healthy participants that are unrelated, and of Western European ancestry, to investigate inter-individual immunological variances by integrating intrinsic, environmental and genetic factors in innate immunity and adaptive immunity. Through the quantification of white blood cells by utilising standardised flow cytometry and correlating with sociodemographic variables, the Institut Pasteur team found that smoking, age, sex, and latent infection with cytomegalovirus, were the main non-genetic factors that affected variation in parameters of human immune cells. The HHGP-Hong Kong will, therefore, replicate and adapt from the study design of Milieu Intérieur recruiting 1,000 healthy participants, drawn from the FAMILY Cohort, to better understand the immunological variance within the Hong Kong population. This Cohort was part of a prospective population-based study in 2007, consisting of 46,001 participants in Hong Kong. It was the first large-scale programme to understand the determinants of physical, mental, and social wellbeing in Hong Kong. A technological platform will be developed to provide a personalized patient management strategy that takes into account individual genetics, previous infection history, resident microbiota, as well as personal lifestyle and environmental factors to define immune health.
