Dr. Zauderer continued, “The hypothesis for evaluating pepinemab in combination with ICIs in PDAC is supported by a robust body of preclinical studies and human clinical data. These data suggest that treatment with the semaphorin 4D (SEMA4D) blocking antibody, pepinemab, may reverse immunosuppression to promote the infiltration and activation of dendritic cells and CD8+ cells into the TME, rendering “cold” tumors “hot” and leading to enhanced efficacy of ICIs such as avelumab.”
