CE Mark for EarlyCDT®-Lung Kit

EarlyCDT-Lung Kit Paves Way for Further Expansion into World Markets

Nottingham, UK - 31 May 2017: Oncimmune Holdings plc (AIM: ONC.L), a leading early cancer detection company developing and commercialising its proprietary EarlyCDT® platform technology, announces it has obtained the CE mark for EarlyCDT®-Lung test in an ELISA kit format. EarlyCDT®-Lung is a simple autoantibody blood test that can detect lung cancer up to four years earlier than other methods.

The CE mark certifies that the kit meets the strict EU standards of manufacturing and quality control dictated by the In Vitro Diagnostics Medical Devices Directive 98/79/EC (IVD Directive). The Company is now ordering its first batch of commercial kits which will be available within four months in time for launch.

The kit has the advantage of running on already well established ELISA-96 well-Microplate-Instruments that hospitals worldwide have as standard equipment in their laboratories.

Geoffrey Hamilton-Fairley, CEO of Oncimmune, commented: "The development and completion of a kit version of the EarlyCDT®-Lung test was a key part of the commercial growth strategy laid out at the time of our IPO. This success positions us to make the test available to hospitals around the world for running in their own laboratories.

"Until it was certain that the EarlyCDT®-Lung® test would successfully transfer to a kit, Oncimmune's commercialisation plans for territories outside of the US were conservative as adoption of the test was likely to be slower if we could only offer a central laboratory test. The CE marked kit now allows us to address these markets and support our distributors with a simple test in a well-known, easy to use format. We believe this development will greatly help us in accelerating our appointment of global distributors and support their ongoing performance."
