Figure 3. A, A positive correlation between changes in tumor OX40 expression and TTP was observed in a limited sample set. TTP did not exhibit any correlation with baseline or fold-change expression of CD8, CD4, or FoxP3. B, Examples of OX40-positive staining at baseline and week 6 in a patient with RCC and a patient with HCC. 20× magnification. 4-μm sections were stained with anti-CD134 clone ACT-35 murine IgG1 antibody (BD catalog #555836). — A, A positive correlation between changes in tumor OX40 expression and TTP was observed in a limited sample set.
