  • Significant changes to the aims and objectives of the study or the study design that were not considered by the full HREAP/HREC.
  • Additions of methodologies, participant cohorts or amendments to the recruitment or consent strategies that present risks to the participants, the research team, or the wider community that were not previously considered by the HREAP/HREC.
  • Additions of new treatments or changes to the safety profile of any investigational medical devices/products.
