Challenges with Mitigations

  • Multiple physicians supporting this trial have led to differences i opinion.
  • Aixial established clear communication pathways to address and resolve differences quickly, to not impede enrollment, medical oversight, safety management, etc.
  • Internal sponsor team turnover resulted in rework, but the Aixial team was able to support and resolve this quickly
  • Aixial project manager turnover (n=1) addressed with senior oversight by stepping into the project to apply their historical knowledge of the project to ease the transition burden on site and sponsor teams
