About Oncimmune

Oncimmune is a leading immunodiagnostics developer, primarily focused on the growing fields of immuno-oncology, autoimmune disease and infectious diseases. Oncimmune has a diversified and growing revenue both from its portfolio of diagnostic products to detect early-stage cancer and its contract discovery and development service business whose platform delivers actionable insights into therapies to the Company's pharmaceutical and biotech partners.

Our understanding of the immune system enables us to harness its sophisticated response to disease to detect cancer earlier and to support the development of better therapies. The key to improving cancer survival is early detection and better selection for therapy. As a company, we are driven by our passion to improve cancer survival and to give people extra time.

Oncimmune's ImmunoINSIGHTS platform enables life science organisations to optimise drug development and delivery, leading to more effectively targeted and safer treatments for patients. Oncimmune's immunodiagnostic technology, EarlyCDT, can detect and help identify cancer on average four years earlier than standard clinical diagnosis. Our lead diagnostic test, EarlyCDT Lung, targets a vast market estimated to grow to £3.8bn by 2024. With over 200,000 tests already performed for patients worldwide and its use being supported by peer reviewed data in over 12,000 patients, we are poised to become an integral component of future lung cancer detection programmes, globally.

Oncimmune's diagnostic products business is located at its laboratory facility in Nottingham, UK and its ImmunoINSIGHTS service business at its discovery research centre in Dortmund, Germany. The ImmunoINSIGHTS business development team are based in the US and Oncimmune is seeking to replicate the Dortmund facility in the US in the medium term.
