What is it? Why is it important?

A newsletter contains information summarising study progress so as to inform participating Site-INV(s), study staff and if applicable study participants.

It is especially useful in:

  • Multi-centre studies with more than one study site
  • Studies that last over a long period of time
  • Studies that recruit a sizable amount of participants

The aim is to motivate, update and train study sites including participants in order to keep the study on everyone’s agenda.

Newsletters are reviewed and approved by the SP-INV prior to being release.


A newsletter should:

  • Be positive and provide a general outlook on study status
  • Respect and maintain data protection issues at all times.

What do I need to do?

Edit a newsletter according to addressee

  • Language: Preferably provide information to participants in local language and refrain from using technical definitions.
  • Content: For a Site-INV(s) the newlsetter can provide more statistical and organisational information, such as:
    • Acknowledgement of participating study sites
    • Overall study progress (e.g. recruitment rate, novel sites)
    • Sharing of emerging new knowledge and experience
    • Adaptations of administrative tasks

A newsletter destined for participants should be considered for studies that last over many years.


The aim of a participant newsletter is mainly to motivate and should be:

  • Adapted based on participant profile (e.g. age, gender, disease type)
  • Edited using easy to understand layman terms
