As our understanding of tumor immunology has advanced, immuno-oncology has made unprecedented progress in improving the outcomes for cancer patients. Still, with the field in its infancy, the full curative potential of IO has yet to be realized. CHIa€™s 4th Annual Immuno-Oncology Summit has been designed to support a coordinated effort by industry players to bring commercial immunotherapies and immunotherapy combinations through clinical development and into the market. This weeklong, nine-meeting set will include topics ranging from early discovery through clinical development as well as emerging areas such as oncolytic virotherapy. Overall, this event will provide a focused look at how researchers are applying new science and technology in the development of the next generation of effective and safe immunotherapies.
