Today’s Webinar:
What is a RESEARCH ADVOCATE?
A research advocate brings a patient viewpoint to
the research process and communicates a
collective patient perspective
Fight CRC’s Research Advocacy Training and
Support (RATS) Program:
• Goal is to improve the ability of research
advocates to effectively participate in the
research process.
• In person meetings, online trainings, and
webinars.
• Continued education and ongoing training and
support

Immunotherapy
The Importance of the PD-1/PD-L1 Pathway
• Inhibiting PD-L1/PD-1 and PD-
L1/B7.1 interactions can restore
antitumor T-cell activity and enhance
T-cell priming
• Antibodies that bind to PD-1 and PD-
L1 are currently in development
• Nivolumab and pembrolizumab are
currently FDA-approved

Summary
• Biomarker testing is becoming more common,
especially in clinical trials
– Testing is usually performed by biopsy, but new
technologies are emerging (e.g. liquid biopsy)
• We are limited by what we don’t know about cancer
biology
– Biomarkers aren’t perfect
• Immunotherapies are emerging as effective treatment
options
– Currently, they do not work for all tumors
