What is it? Why is it important?

Infrastructure includes both physical structures and logistics. Depending on the study, infrastructures are important aspects that must be carefully evaluated and planned.


Aspects to consider might include:

  • Facilities: patient examination rooms, office space, Phase I Unit, public transport, parking, etc.
  • Storage space: study documents and materials, biological samples, IMP/IMD
  • Laboratory: handling and analysis of biological samples
  • Logistic tools: freezers, measuring instruments, computers, printers, defibrillator, etc.

What do I need to do?

As a SP-INV or Site-INV, based on the planned study, define study infrastructure and storage requirements and compare against current local inventory.


Clarify and ensure access to:

  • Local infrastructure at planned study site
  • Additional premises including blocking of required time slots
  • Availability of local storage space


Whether it is an IMP/MD, study documents, or biological material, access control including protection against damage must be guaranteed.

Include required infrastructure in the cost estimate of your study.

The cost estimate should cover required infrastructure from concept until completion. Do not forget the archiving period that will require many years of available storage space.
