Companion Diagnostics (CDx) Services
What are companion diagnostics?
TOWARDS REGULATORY AND MARKET ACCESS
Companion Diagnostics (CDx) in the are defined as a device that is essential for the safe and effective use of a corresponding medicinal product.
They are designed to either identify patients who are most likely to benefit from that medication before or during treatment or to identify patients who may be at higher risk of experiencing serious side effects as a result of that medication.
With the implementation of the In Vitro Diagnostic Medical Device Regulation (IVDR), companion diagnostics are now subject to new regulatory requirements that have a significant impact on their development and commercialization.
Since CDx are ideally co-developed with pharmaceutical manufacturers, there are unique challenges involved in bringing together these two distinct regulatory frameworks.
We understand the regulatory complexities involved in the design and development of companion diagnostics, as well as in the development of personalized medicine, which is why we have dedicated regulatory teams with expertise in IVDs and medicinal products that can work together to support your co-development efforts.
This enables us to navigate the challenges involved in bringing companion diagnostics to market, ensuring you can achieve regulatory compliance and commercial success.
