Companion Diagnostic solutions with GenDx: Your partner from start to finish
Our Companion Diagnostics (CDx) services are designed to facilitate and support the pharmaceutical precision medicine revolution. New pharmaceutical therapies in the field of precision medicine require the presence of specific biomarkers or genetic profiles, which impact the eligibility or susceptibility of patients for the pharmaceutical therapy. For example, the genetic HLA profile of a patient can determine the response of a patient to a particular pharmaceutical therapy (read more here). The continuous progress in the field of precision medicine goes hand in hand with an increasing need for companion diagnostics that allow accurate patient selection. GenDx, as a strong CDx partner, will support clinical study validation, ease navigating regulatory landscapes, and contribute to the success of a pharmaceutical therapy.
At GenDx, we do everything in-house, from Research & Development to Regulatory Affairs ensuring an efficient and seamless process. In May 2022, GenDx became the first company in the field of transplantation diagnostics to attain IVDR certification for their HLA typing reagents and analysis software. Our analysis software NGSengine is recognized as the best-in-class solution for the analysis of NGS-based HLA typing, ensuring accuracy and reliability in analyzing one of the most complex and heterogenous gene families.
We offer our cutting-edge technology and extensive expertise in molecular diagnostics for complex, polymorphic genes, such as immuno-related genes like HLA, KIR, and MICA/MICB. Together with our evidencable experience with IVDR, GenDx will be your knowledgeable and reliable partner in supporting the development of your CDx, organization of clinical performance studies, and registration of new CDx products.
