This amendment No. 5 to Schedule 13D (this “Amendment No. 4”), amends and supplements the Schedule 13D filed on June 10, 2020 (as amended, the “Initial 13D”) by the Reporting Persons, relating to the common stock, par value $0.001 per share (the “Common Stock”), of VolitionRx Limited, a Delaware corporation (the “Issuer”).
