OUTLINE: This is a dose-escalation study of talimogene laherparepvec.
Patients receive talimogene laherparepvec intralesionally via endoscopy on weeks 1, 4, 6, and 8. Patients receive 5-fluorouracil intravenously (IV) by bolus and over 46 hours, leucovorin IV bolus, and oxaliplatin IV over 2 hours on weeks 2 and 4. Patients also receive capecitabine orally (PO) twice daily (BID) followed by radiation therapy for 28 fractions on days 1-5 of weeks 8-13. Patients undergo resection surgery on weeks 21-25.
After completion of study treatment, patients are followed up for 30 days and up to 5 years thereafter.
