Controlled clinical trials are the accepted gold standard for the assessment of therapeutic efficacy and are a requirement for the approval of new drugs by regulatory agencies.

Various limitations of Phase III studies (e.g. highly selected subject(s), limited subject(s) numbers etc.) make it mandatory to perform additional research following marketing approval of the drug. Possible aims of PASS and PAES (Post Authorization Safety / Efficiacy Studies) are to gain information about drug utilisation, to identify the rare adverse drug reactions (ADRs) and specific subject groups at risk of ADRs under normal every-day practice.

These studies are mainly scientific observational studies, prospective in design and comprise all characteristics of a one- or two-armed cohort-study. In addition the decision regarding choice and execution of the therapy is left completely to the discretion of the individual physician. If conducted according to actual guidelines, these can be regarded as scientifically valid research instruments.

psn offers a comprehensive service portfolio for PASS/PAES such as:

  • Planning and designing (incl. printing) of all necessary documents
  • Placement of the study at GP or clinic sites
