About GxPlex

What is GxPlex?

GxPlex is a collaborative database, organized like a wiki, that brings together legal articles and guideline paragraphs relevant to the preparation, conduct, and reporting of clinical studies — and to clinical research more broadly.

The name can be read as "GxP lex" (the legal side of GxP) or "Gx-plex" (the complexity of the systems and processes involved). Both readings are intentional, and both are true.

Why does it exist?

Clinical research is one of the most heavily regulated fields out there — and the rules don't always agree with each other. A requirement that applies to a clinical trial in one EU country might not apply the same way in another. A reporting obligation for a human medicine might look completely different for a medical device.

• These differences are often small, but they can be critical, and missing them can be costly.

How should we go about it?

Large organizations often build their own internal lists of relevant regulations to manage this. But that approach has limits:

• Lists need constant updating as laws change.
• Smaller companies, clinical sites, and individual professionals usually don't have the resources to build or maintain anything like this.
• Important changes can slip through unnoticed.

GxPlex takes a different approach: instead of each organization building and guarding its own list, the clinical research community builds one together, openly.

How is it organized?

References (laws, articles, guideline paragraphs) are entered into the database as contributions, each tagged with information such as:

   • Area of validity — region or country 

   • Scope — general requirement, IMP, Medical Device, IVD, GMP, GEP, etc. 

   • Type of document — treaty, legislative act, guideline, scientific article, etc. 

   • Document name, version/revision, and link to the official source 

   • Document part — chapter, article, section, etc. 

   • Language 

   • Table of content/Modules within GxPlex 

   • Status — current, not yet in force, or superseded 

   • Access restrictions — whether the source material is copyrighted (referencing is always allowed; copy-pasting protected content is not) 

This structure makes it possible to search by topic and compare how different countries or research scopes handle the same question — something that's normally very time-consuming to do manually.

What are we trying to achieve?

• Help anyone — from large sponsors to individual professionals — find the regulatory requirements that actually apply to them.
• Make it easier to start activity in a new country or region by surfacing what's different and what to watch out for.
• Allow direct comparison of requirements across countries and research scopes.
• Give visibility to regions where clinical research is still developing, and where more information could encourage more activity.

GxPlex's core functions are, and will remain, free to access.

The goal is reach and impact, not gatekeeping.
