Figure 2. Change in tumor burden under combined treatment of OX40 agonist and PD-L1 antagonist over time.

The diameters of new and existing lesions were measured in millimeters every eight to ten weeks. Blue blocks denote baseline lesions. Orange blocks are new metastatic lesions, and yellow are new lymphadenopathy. * The periportal lymph node detected at week ten was not included in overall tumor burden at week 18 because it decreased to less than 10mm.
