Oncimmune Signs Research Agreements in Ovarian and Liver Cancer

Samples Sourced to Validate EarlyCDT® in New Indications

Nottingham, UK - 4 July 2016: Oncimmune Holdings plc (AIM: ONC.L) ("Oncimmune" or the "Company" or the "Group"), a leading early cancer detection company developing and commercialising its proprietary EarlyCDT® platform technology, announces that is has signed research agreements with Egybiotech, a private research company with a broad research portfolio in the areas of cancer research, and Aarhus University Hospital ("Aarhus"), Denmark.

Under these agreements, Egybiotech and Aarhus provide Oncimmune with prospectively collected blood samples and associated clinical data on each patient in order to further clinically validate the Company's EarlyCDT® platform technology in liver and ovarian cancer, respectively. Oncimmune will use the samples to validate panels of autoantibodies as diagnostic tests capable of distinguishing between malignant and non-malignant liver and ovarian diseases, particularly at an early stage.

Geoffrey Hamilton-Fairley, CEO of Oncimmune commented: "Current biomarkers for liver and ovarian cancer perform poorly and our EarlyCDT® technology has the potential to allow earlier diagnosis of these serious diseases and improve patient outcomes. The agreements are a significant further step in the final clinical validation of EarlyCDT® liver and ovarian and will enable us to remain on track towards the goal of launching the tests commercially in 2017. "
