Your Easy Guide to Clinical Studies

The protocol is the core document that describes the background, rationale, objective(s), design and methodology, statistical method, including safety aspects of a study.

 

By approving and signing the study protocol, the SP-INV, including any participating Site-INV(s) and other potential signees (e.g. statistician) confirm their commitment to conduct the study according to:

• Specifications given in the protocol
• The Declaration of Helsinki
• If applicable ICH-GCP guidelines
• ISO 14155 for studies with medical device
• The Swiss law (e.g. data protection laws, HRA, ClinO, ClinO-MD, HRO)

 

A protocol must have clearly marked identifiers (e.g. protocol version number, release date). In the event of protocol changes or amendments, requires that identifiers are adapted accordingly. This is important as ECs or RAs (e.g. Swissmedic) who approve study protocols, do this on the basis of a particular protocol version.

As a SP-INV:

• Select and download the official protocol template applicable to your study from the swissethics webpage
• Fill in all required study information (e.g. rational, study design, safety issues)
• Include reviews by applicable experts who contribute to its content (e.g. statistician, quality-, project-, data manager, study nurse)
• Consider to have the protocol reviewed by an impartial expert who can provide important professional support
• Place the synopsis at the beginning of the protocol

 

Invest sufficient time in protocol development, as a well prepared and thought through protocol will:

• Avoid unexpected difficulties, requiring protocol amendments due to protocol inconsistencies during study conduct
• Save not only resources and costs, but also the required time needed to complete the study (e.g. amendments are costly and do significantly delay the study)
