Abstract

Modified or attenuated therapeutic viruses in combination with a chemotherapeutic agent, and methods for administering therapeutic viruses in combination with a chemotherapeutic agent to a subject for controlling viral titer, are provided. The combination of a therapeutic virus and chemotherapeutic agent can be used in methods of treating diseases, such as proliferative and inflammatory disorders, including as anti-tumor agents. The combination can also be used as a preventive measure or as a treatment to reduce or eliminate symptoms associated with oncolytic viral therapy.
