Combination Treatment of Human Pancreatic Cancer Xenograft Models with the Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor Erlotinib and Oncolytic Herpes Simplex Virus HF10

Background There is the potential to use replication-competent oncolytic viruses to treat cancer. We evaluated the efficacy of HF10, a herpes simplex virus type 1 (HSV-1) mutant, in combination with erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor, in human pancreatic cancer xenograft models.
