Researchers at the Earle A. Chiles Research Institute, a division of Providence Cancer Institute in Portland, Oregon, joined leading cancer immunotherapy professionals around the world for the largest cancer immunotherapy conference, the 36th annual meeting of the Society for Immunotherapy of Cancer (SITC21).
Our team of internationally recognized experts were featured in education programs and contributed to 14 abstracts selected for presentation at this year’s conference.
Of note, Bernard A. Fox, Ph.D., member, and Harder Family Endowed Chair for Cancer Research, Molecular and Tumor Immunology Laboratory, and Andrew D. Weinberg, Ph.D., member, and Judith Ann Hartmann Endowed Chair, Basic Immunology Laboratory, participated in two preconference symposiums.
Dr. Fox served as a program co-organizer of the World Immunotherapy Council's 4th Young Investigator Symposium. This program brings together young scientists and future leaders to highlight worldwide initiatives in cancer immunotherapy and facilitate scientific exchange and networking.
Dr. Weinberg led a panel discussion on "Myths vs. Knowledge on Clinical Therapeutic Mechanisms - Lessons Learned" as part of the Immuno-Resistance and Sequencing Symposium. He shared with attendees how OX40 agonists can increase tumor-reactive T cells in a tumor and lead to improved survival outcomes for patients.
