Figure 3 from IPH5201, an Anti-CD39 mAb, as Monotherapy or in Combination with Durvalumab in Advanced Solid Tumors
<p>IPH5201 treatment decreases tumoral CD39 enzymatic activity. The Wachstein–Meisel assay detects the presence of phosphates hydrolyzed from ATP due to enzymatic activity of CD39. <b>A,</b> Representative histology images of tumor tissues with reduction in CD39 enzymatic activity after treatment with IPH5201. <b>B,</b> Enzymatic activity was assessed by semi-quantitative scoring methodology for tumor, stroma, and vasculature. The pathologist conducted an overall assessment to determine whether a significant decrease was present on day 15 compared with screening biopsies.</p>
