IVDR: What Does It Mean for Manufacturers of In Vitro Diagnostic Devices?

by Claudia Panizzi, MD Compliance Specialist @PQE Group

How to register a medicinal product in Europe? 

The In Vitro Diagnostic Medical Devices Directive 98/79/EC (IVDD) guided the market of in vitro diagnostic devices for more than 20 years. However, it officially ended in May 2022 its effectiveness, giving way to the In Vitro Diagnostic Regulation (IVDR). Many manufacturers have found themselves unprepared for the changes, facing narrow deadlines and new, stricter requirements. 

 

Deadlines for Transitioning to IVDR 

Under the original rules, manufacturers had to switch from IVDD to IVDR of self-declared IVDs by the following dates:       

  • May 26, 2025, for Class D devices, 
  • May 26, 2026, for Class C devices, 
  • May 26, 2027, for Class B devices, 
  • May 26, 2027, for Class A devices that are sold under sterile conditions.

For Class A devices that are not sterile, IVDR became mandatory from May 26, 2022, with no transition period. 

IVDR Amendments: Regulation 1860/2024/EU 

In 2024, Regulation 1860/2024/EU introduced important changes. The main purpose of this regulation was to give manufacturers and notified bodies more time to adjust the passages from IVDD to IVDR.  

The new deadlines for the passage of self-declared IVDs from IVDD to IVDR are:

  • December 31, 2027 for Class D devices,
  • December 31, 2028 for Class C devices, 
  • December 31, 2029 for Class B and Class A (sterile) devices.

Extended Validity of IVDD Certificates 

Another change introduced by Regulation 1860/2024/EU concerns the validity of certificates issued under the old IVDD. Certificates that were still valid at the date of July 9th 2024, are now valid until December 31, 2027. Certificates that expired before July 9, 2024 will also be extended, if manufacturers meet specific conditions, including: 

  • Keeping compliance with IVDD under surveillance, 
  • No significant device changes or risks considered unacceptable, 
  • Implementing a Quality Management System (QMS) compliant with IVDR by May 26, 2025, 
  • Signing an agreement with a notified body for IVDR certification by May 26, 2025 (or by September 26, 2025, for some steps). 

In addition, originally IVDR included a "sell-off" period, in other hands, meaning that after one year from the original transition deadline, IVDs sold under IVDD could no longer be sold. However, Regulation 1860/2024/EU removed this restriction to avoid lacking of diagnostic devices on the European market. 

 

Legacy Devices and IVDR Requirements 

The new transitional provisions cover devices considered "legacy devices" i.e. all those devices placed on the market still in accordance with the IVDD (98/79/EC), after the implementation date of Regulation 746/2017/EU (IVDR) and with a valid certificate or declaration of conformity issued in accordance with the same directive.  

These devices are still allowed on the market, but they must follow some IVDR prescriptions, such as:

  • Vigilance, including reporting serious incidents and implementing corrective actions, 
  • Following Post-Market Surveillance (PMS) requirements, including PMS plans, Post-Market Performance Follow-Up (PMPF), and Periodic Safety Update Reports (PSUR) for higher-class devices, 
  • Registering economic operators and devices (now the registration is mandatory in the national databases and voluntary in EUDAMED. However, the EUDAMED registration is highly recommended).  

Notified bodies that issued IVDD certificates must continue to provide the appropriate surveillance of these devices, unless the manufacturer chooses a different notified body for the future IVDR certification, in which case the new notified body could bring the surveillance of the legacy devices if required. 

 

The Pressure on Manufacturers and Notified Bodies 

One of the big problems with the new IVD regulation is the limited number of notified bodies available to handle IVDR certifications. With IVDD, only about 20% of devices required certification. With IVDR, this number has increased to about 80 percent of devices requiring certification. To date, only 13 notified bodies are able to issue IVDR certifications. This increase in requirements compared to the small number of notified bodies that can certify devices under IVDR has created a bottleneck, slowing down the process for many manufacturers.  

During the transition period, a great deal of effort is required of manufacturers to meet IVDR requirements, particularly with regard to scientific validity and post-marketing surveillance.  

Postmarket surveillance has become more challenging, with new requirements based on the new risk classes of IVDR devices, such as implementation first in a PMS plan and then in a PMS report or periodic safety update report (PSUR) for higher risk devices. 

The development of performance and clinical trials is more rigorous in IVDR. Many manufacturers who, under IVDD, have not demonstrated strong performance evidence must now demonstrate that they have robust, diligently conducted studies with sound scientific underpinnings.  

Many manufacturers will now have to collaborate with clinical research organizations (CROs) to conduct these studies.  

 

IVD world for women's health 

There are many in vitro diagnostic devices related to women's health; pregnancy tests, Kit for HPV Screening test, software for genetic mutation analysis of major female cancers (breast and uterus) - these are just a few of the many in vitro diagnostic devices dedicated to women's health. Below are some examples of IVDs that fall under the IVDR regulation that will need to meet the new regulatory requirements (deadlines). 

IVD 

Self-testing / Near patient test /  Professional use 

Class of risk according to IVDR 

Deadlines according to IVDR (available on the market) 

Pregnancy tests 

Self- testing  

B 

May 27, 2025 or at expiring date of the Certificate  

Kit for HPV Screening test 

Professional use  

C 

Dec 31, 2028

Software for genetic mutation analysis of major female cancers 

Professional use  

C 

Dec 31, 2028 

Many examples could be added. PQE can also support IVD manufacturers dedicated to women's health through FemTech. FemTech supports manufacturers of IVDs dedicated to women's health to ensure clinical device compliance.  

 

Conclusion 

The transition from IVDD to IVDR poses great challenges for manufacturers. They must now meet for example more stringent clinical and post-market requirements. Although the revised deadlines in Regulation 1860/2024/EU provide more time to comply with Regulation 746/2017/EU, manufacturers still face several challenges in ensuring that their devices meet IVDR standards. Acting quickly and ensuring sound science and robust documentation is critical to successfully address this transition.
