Talimogene Laherparepvec in Treating Patients with Locally Advanced, Metastatic, or Refractory Pancreatic Cancer That Cannot Be Removed by Surgery

Trial Status: Active

This phase I trial studies the side effects and best dose of talimogene laherparepvec in treating patients with pancreatic cancer that cannot be removed by surgery and has spread from where it started to nearby tissue, lymph nodes (locally advanced), or to other places in the body (metastatic), or that does not respond to treatment (refractory). Talimogene laherparepvec may help infect and kill tumor cells and activate the body’s own immune cells to destroy the tumor cells throughout the body.

I. To determine the rate of dose limiting toxicity at tested doses of talimogene laherparepvec administered endoscopically to pancreatic tumors, and to identify a maximum tolerated dose (MTD).


I. To determine the activity of talimogene laherparepvec in pancreatic cancer, as measured by change in size of the injected lesion(s), overall response rate by immune related response criteria and Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1, and progression free survival (PFS) and overall survival (OS) at 6, 12, and 24 months.

II. To explore the immune effects of talimogene laherparepvec and predictors of response as determined by immunohistochemistry (IHC), flow cytometry, and genomic analysis of tumor and immune cells.

OUTLINE: This is a dose-escalation study.

Patients receive talimogene laherparepvec endoscopically at weeks 1, 4, 7, and 10 in absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3 months for 1 year, and then annually for 5 years.
