Companion Diagnostics IVDR and Companion Diagnostics FDA CDx

Regulatory consultancy support for the development of companion diagnostics

CDx regulatory requirements

Companion Diagnostics FDA and IVDR

Companion Diagnostics FDA and Companion Diagnostics IVDR (CDx), personalized medicine, and clinical trials assay (CTA) require specialized regulatory knowledge and practical experience. This sector is experiencing a multitude of changes as the technology evolves at the same time as the regulations are in flux; this includes:

  • Clinical Trial Regulation (CTR) in Europe
  • IVD Regulation in Europe
  • Changes to the classification of some CDx devices in the US
  • Transition of Lab Developed Test (LDT) in the US to FDA-cleared services as 510(k) or PMA.


All stakeholders are learning by doing. Our IVD experts have extensive experience working with both pharma and diagnostic partners in this sector, supporting both parties to help them work efficiently together. Not all assays used in clinical trials will become commercial IVD assays, and the Qserve team has experience in navigating this tricky area in both Europe and the US.

The team provides regulatory consultancy support across the entire IVD product development lifecycle, from developing a clear strategy to supporting clinical trial assays of IVD clinical performance studies to the preparation of technical files for Europe or 510(k) or PMA regulatory submissions to bring the CDx to the US (Companion Diagnostics FDA) and European markets (Companion Diagnostics IVDR).

CDx guidance for EU-IVDR

There are a lot of questions raised about IVDR CDx guidance because IVDR is still a huge mystery for companies. The EU-IVDR defines companion diagnostics as devices that are essential for the safe and effective use of corresponding medicinal products to identify patients who are most likely to benefit. 

Companion Diagnostics and Personalised Medicines are advancing at the same time as the regulations to support them in Europe evolve. This is challenging for not only the pharma and diagnostic partners but all stakeholders. 

Specific IVDR CDx guidance

  • IVD Clinical Performance study design, plans and reports
  • In-house tests (distance sales, exemptions)
  • Conformity assessment route to CE Mark (Class C)
  • CE certification of CDx
  • Notified Body selection
  • Notified Body review process, including EMA coordination of drug approval application (CTR)

Annex XIII and Annex XIV

  • Guidance and interpretation
  • Gap assessments and remediation
  • Write Clinical Performance Study Plans (CPSP) and Reports
