Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Titles & IDs
Public title
Investigation and prevention of Rheumatoid Arthritis before symptom onset
Scientific title
Prospective observational cohort of unaffected first-degree relatives (FDR) of probands with Rheumatoid Arthritis (RA) and healthy controls followed for five years with the simultaneous collection of tissue samples; designed to examine the role of genetic and environmental factors influencing the development and progression of RA-related autoimmunity and to identify and explore immunological alterations prior to the onset of disease, to establish the proportion of FDRs who develop RA defined by the ACR 2010 classification criteria at 5 years and to identify biomarkers in FDRs prior to and at onset of disease for disease prediction, diagnosis and prognosis of RA and to direct and guide treatment.

Description of intervention(s) / exposure
Observational Study - To follow prospectively a cohort of unaffected first-degree relatives (FDR) of people with rheumatoid arthritis (RA) annually for five years. FDR will be evaluated and data obtained including demographic information, medical history, environmental exposures questionnaire, connective tissue disease screening questionnaire, physical examination, joint counts and tissue samples collected including blood, mouth and faecal swabs.

Outcomes
Primary outcome [1] 294065 0
The proportion of FDRs who develop RA defined by the ACR 2010 classification criteria at 5 years.


Timepoint [1] 294065 0
5 years
Secondary outcome [1] 312438 0
The identification of genetic factors contributing to the development of RA. DNA will be collected and all patients genotyped.
Timepoint [1] 312438 0
Baseline, 1, 2, 3, 4 and 5 years after commencement of observation
Secondary outcome [2] 312677 0
The identification of microbial factors contributing to the development of RA. Mouth and faecal swabs will be collected and using next-generation sequencing techniques including shotgun metagenomic sequencing, 16S rRNA metagenomic sequencing and microbial metatranscriptomics we will analyse the microbial communities.
Timepoint [2] 312677 0
Baseline, 1, 2, 3, 4 and 5 years after commencement of observation
Secondary outcome [3] 312678 0
The identification of environmental factors contributing to the development of RA. Environmental questionnaires specifically designed for this study will be completed at all time points.
Timepoint [3] 312678 0
Baseline, 1, 2, 3, 4 and 5 years after commencement of observation
Secondary outcome [4] 312679 0
The identification of immunological factors contributing to the development of RA. Serum and peripheral blood mononuclear cells will be separated from collected whole blood and using various techniques including flow cytometry, cell sorting techniques, ELISA and qPCR; we will identify, enumerate and phenotype immune cells contributing to RA development.
Timepoint [4] 312679 0
Baseline, 1, 2, 3, 4 and 5 years after commencement of observation
Secondary outcome [5] 312680 0
To identify predictive risk biomarkers prior to the onset of disease. All genetic, microbial, environmental and immunological data will be analysed for potential biomarkers of disease development.
Timepoint [5] 312680 0
Baseline, 1, 2, 3, 4 and 5 years after commencement of observation
