Volition's Nu.Q™ Vet Assay Detects Two Common Canine Cancers

AUSTIN,Texas,April 29,2020 --VolitionRx Limited (NYSEAMERICAN: VNRX) ("Volition") today announced results from its first proof of concept study conducted by Texas A&M University ("TAMU"). At a specificity of 90%,a single Nu.Q™ Vet assay detected almost 70% of both Canine Hemangiosarcoma and Canine Lymphoma with Areas Under the Curve ("AUC") of 84.5% and 83.1% cancer versus healthy,respectively. These two cancers alone represent almost a third of all canine cancers.

Commenting on the results,Dr. Heather Wilson-Robles,an Associate Professor at TAMU and Chief Medical Officer of Volition Veterinary Diagnostics said,"The proof of concept results in these two very prevalent canine cancers give us confidence to move forward with other Nu.Q™ Vet assays in our pipeline,and with the larger range of cohorts and trials we have collected and planned. Clearly,we still have work to do as this single assay did not detect one of the other top five canine cancers,Canine Osteosarcoma,which was the third cancer tested in this study. However,I am delighted to see such positive results in these two significant cancers and look forward to reporting further data over the coming quarters with additional Nu.Q™Vet assays,this time tested on an automated platform."

Dr. Terry Kelly,Chief Scientific Officer of Volition America commented,"It is exciting to see such strong results from our first Nu.Q™ Vet study conducted at Texas A&M University Veterinary Hospital. It is also interesting to note the similar patterns of detection seen in both canine and human samples confirming that the Nu.Q™ platform does appear to be useful in more than just human diagnostics. As with human diagnostics,there are currently no accurate,simple,affordable cancer screening tests available in veterinary medicine and yet 25% of dogs will develop cancer at some stage of their life. I look forward to completing the planned trials and to launch our first Nu.Q™ Vet product in the U.S. that we expect to occur in 2020."

The U.S. is currently the largest veterinary market in the world with almost 70 million pet dogs and approximately 6 million cancer diagnoses each year. It has a clearly defined regulatory pathway via the USDA,requiring fewer and smaller clinical studies than the FDA process for human diagnostics which generally allows a much faster route to revenue for veterinary products as compared to human products.

About the Study

The canine cancer samples (n=156,Hemangiosarcoma =44,Lymphoma = 69,Osteosarcoma =65 including all stages ) were taken from the National Institute of Health (Division of Cancer Treatment and Diagnosis Tumor Repository) and the controls were taken from 39 healthy controls canine volunteers at TAMU.

Hemangiosarcomais a highly malignant cancer representing 5% of all non-cutaneous malignant tumors that develops almost exclusively in dogs. It can spread rapidly,causing tumors almost anywhere in the body. It is most often found in the dog's heart and spleen. Many times,it is in the advanced stage before it is diagnosed.

Canine Lymphoma is a cancer of a type of blood cell (lymphocytes) and lymphoid tissues and is one of the leading cancers in dogs representing more than 25% of all canine cancers.

Canine Osteosarcomarefers to the most common bone tumor found in dogs. Bone cancer can affect any breed of dog,but it is more commonly found in the larger breeds. It represents approximately 8% of tumors seen in dogs.
