Multi-level, bi-national committees drive ASPREE’s high standards of research practice, data capture, study findings and publications.


The ASPREE International Steering Committee (ISC) is comprised of senior researchers in Australia and the United States and is responsible for the overall management and progress of the project.

ASPREE management is structured so that specialist committees look after different aspects of the project, such as the International Data Management Committee, and provide the ISC with accurate, timely information.

ASPREE Project Committees

The Principal Investigator Committee

The Principal Investigator Committee is responsible for governance of the project in accordance with the requirements of the funding bodies and their institutions. It also oversees policies related to data availability and access. 

The International Steering Committee

The International Steering Committee (ISC) is responsible for the overall management and conduct of the ASPREE Project in Australia and the USA. This committee, which meets quarterly, oversees protocol implementation and adherence, financial management and study progress. Various sub-committees and sub-studies report to the ISC.

The International Executive Committee

The International Executive Committee (IEC) is a smaller committee derived from the ISC, that meets twice a month. This committee oversees operational management, study and sub-study progress (including generation of reports), data access and publications. Various sub-committees and sub-studies report to the IEC.

Monitoring and Safety Board

The NIA (the major funding body for the project) appointed an independent Data Safety and Monitoring Board (DSMB) with the responsibility of monitoring quality control of the data, trial progress and safety aspects every six months during the ASPREE clinical trial.

The independent Observational Study Monitoring Board (OSMB) appointed by the NIA and NCI, monitors retention and data quality and any new ancillary studies during the ASPREE-XT study.

Both boards report to the NIA.

The International Data Management Committee

The International Data Management Committee (IDMC) monitors the ASPREE data management processes in Australia and the USA. The IDMC reviews data reports generated by the Data Management Committee (DMC) for completeness and quality. The IDMC Chair reports to the IEC on data management issues (apart from data access) associated with the study.

The Data Management Committee

The Data Management Committee (DMC) is responsible for the project’s web-based data system: overseeing programming and changes to the database and day-to-day management of the database and systems of data collection. The DMC prepares reports and interrogates the database to respond to queries from study investigators and managers, in addition to resolving issues relating to data capture and the database functionality.  It reviews reports generated by the database and the data from the quality assurance program. The DMC reports to the IDMC.

Bio-specimen Access Committee

The Bio-specimen Access Committee is responsible for review and approval of the use of ASPREE’s stored bio-specimens for genomics, biomarkers and any other analyses.

The Endpoint Adjudication Committee

The Endpoint Adjudication Committee (EAC) evaluates ASPREE participant outcomes while still blinded to assigned treatment in the ASPREE trial (100mg aspirin or matched placebo).  Specialist sub-committees examine relevant clinical records to adjudicate specific endpoint outcomes of: dementia, cancer, cardiac events, stroke, cause of death, disability, depression and clinically significant bleeding.  Each sub-committee has members from Australia and the USA with expertise relevant to the clinical or health event to be adjudicated.

Australian Management Committee

The Australian Management Committee is responsible for implementing the project in Australia, monitoring study progress and ensuring adherence and standardisation throughout the study across the sites. 

Australian Operations Committee

The Australian Operations Committee monitors and manages the day to day operations of Australian staff, ensuring compliance with the study protocol and objectives. Responsibilities include keeping study staff up to date on study procedures and activities, monitoring study conduct and providing instruction and refresher training. Operations meetings are held monthly and report to the Australian Management Committee.

United States Operations Committee

The United States Operations Committee is responsible for implementing the study, monitoring progress, ensuring adherence and standardization throughout the many study sites in the United States. This committee ensures quality control review of laboratory data, clinical measurements and data collection, completeness of data and transfer of data to the Data Management Center, site monitoring and appropriate source documentation.

Working Groups

The Presentations, Publications and Ancillary Studies Committee (PPA) reviewed all publications and presentations borne from the ASPREE clinical trial and sub-studies.

Since 2020, Special Interest Working groups, oversee publications (data analysis and manuscript preparation), grant applications and future studies into aspects of health or disease in the ASPREE project. Each group reports progress of publications to the IEC.

Current Special Interest Working Groups include:

  • Microbiome & ALSOP (Australian Longitudinal Study of Older Persons) sub-studies
  • Cancer / sub-types
  • Cancer genomics
  • Cardiovascular disease/hypertension
  • Dementia
  • Depression
  • Disability and frailty
  • Genomics
  • Medication use (Conmeds)

Aspirin and anaemia risk in older adults

Aspirin and anaemia risk in older adults

A new analysis of ASPREE trial data has found that prolonged daily aspirin use increases the risk of anaemia in some older adults. Findings from ASPREE-Anaemia, a sub-study of the ASPREE trial, may help GPs identify older patients at higher risk of anaemia and who may benefit from regular monitoring for development of the condition.

Poor gait/handgrip linked to dementia risk

Poor gait/handgrip linked to dementia risk

Walking speed and grip strength could be early indicators of dementia before the onset of noticeable symptoms, new findings from the ASPREE trial reveals. Researchers found slow walking speed combined with weak hand grip was a stronger predictor of cognitive decline and dementia in older adults than either measure alone.
