Current Primary Outcome Measures  ICMJE
 (submitted: April 11, 2016)
  • Number of Participants With Adverse Events [ Time Frame: From first dose of talimogene laherparepvec until 30 days after the last dose; the median duration of treatment was 44.0 days, 22.0 days, and 11.5 days in each group respectively. ]
    A serious adverse event is defined as any untoward medical occurrence that at any dose results in death, is life threatening, requires hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, is an important and significant medical event that, based upon appropriate medical judgment, may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed above.
  • Number of Participants With Talimogene Laherparepvec Detected in Blood and Urine [ Time Frame: Treatment Day 1 predose and 2, 6, 12 and 24 hours postdose, and Week 3 and 6 at (predose and 2 hours postdose. ]
    Samples of blood and urine collected before and up to 24 hours after dosing were tested for the presence of talimogene laherparepvec deoxyribonucleic acid (DNA) using a validated quantitative polymerase chain reaction (qPCR) assay.
  • Number of Participants Positive for Anti-herpes Simplex Virus-1 (HSV-1) Antibodies [ Time Frame: Week 0 (Day 1, predose) and Week 3 ]
    Anti-HSV-1 antibodies were detected using an enzyme-linked immunosorbent assay (ELISA).
Original Primary Outcome Measures  ICMJE
 (submitted: November 17, 2006)
  • Adverse event summaries of events captured prior to and following treatment to end of study
  • Effects on hematology, biochemistry as changes from values obtained prior to treatment and summaries of clinically significant abnormalities
  • Effects on vital signs
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: April 11, 2016)
  • Change From Baseline in Sum of Longest Diameters of Injected Tumors [ Time Frame: Baseline and Week 6, 12 and 18 ]
    Spiral computed tomography (CT) scans were performed to assess tumors at screening and at Weeks 6, 12 and 18 after the initial dose.
  • Number of Participants With Overall Objective Response [ Time Frame: Every 6 weeks until 12 weeks after the last dose; the median duration of treatment was 44.0 days, 22.0 days, and 11.5 days in each group respectively. ]
    Tumor response was assessed via CT scan by the investigator using Response Evaluation Criteria In Solid Tumors (RECIST) v1.0 guidelines. Objective response is defined as a complete response (CR) or partial response (PR). CR: Disappearance of all target and non-target lesions, normalization of tumor marker level and no new lesions and with confirmation no less than 4 weeks after the criteria for CR is first met. PR: At least a 30% decrease in the sum of longest diameters of target lesions taking as reference the baseline sum of the longest diameters, absence of non-target lesion progression, and no new lesions. These criteria must be confirmed no less than 4 weeks after they are first met.
  • Change From Baseline in Pain Intensity [ Time Frame: Baseline and Weeks 3 and 6 ]
    Pain was assessed by the participant using a validated Visual Analog Scale (VAS) pain assessment instrument. A single 10-cm line was used with the leftmost end (0 cm) representing "no pain" and the rightmost end (10 cm) representing "worst pain". The distance was measured from the leftmost part of the scale to the mark made by the participant indicating pain level.
Original Secondary Outcome Measures  ICMJE
 (submitted: November 17, 2006)
  • Tumor response assessed via CT scan using RECIST
  • Survival time assessed from first injection of OncoVEX
  • Effects on pain relief using a patient self-assessment pain scale

Descriptive Information
Brief Title  ICMJE Talimogene Laherparepvec in Patients With Unresectable Pancreatic Cancer
Official Title  ICMJE Targeted Delivery of OncoVEX^GM-CSF by Endoscopic Ultrasound (EUS)-Guided Fine Needle Injection (FNI) in Patients With Irresectable Pancreatic Cancer: A Pilot Multinational Experiment on Safety and Proof of Concept
Brief Summary The purpose of the study is to assess the safety of injections of talimogene laherparepvec into patients with pancreatic cancer that cannot be removed by surgery. The study will also test whether the injections are effective in treating the tumor.
Detailed Description

Talimogene laherparepvec is a conditionally replication competent herpes simplex type-1 virus designed for use in solid tumors. It has been specifically modified to replicate in tumors and to provide a local source of the immune-stimulating cytokine, granulocyte macrophage colony stimulating factor (GM-CSF). It is injected directly into cancer tumors and is believed to destroy tumor cells by direct infection of the tumor cells and an enhanced immune response due to the release of tumor antigens and GM-CSF expression.

This was an open-label, dose-escalation study evaluating the safety and efficacy of talimogene laherparepvec administered by direct injection into pancreatic tumors using endoscopic ultrasound (EUS)-guided fine needle injection (FNI). Only 1 tumor mass within the body and tail of the pancreas was injected in any participant. The protocol called for evaluation of 4 dosing regimens in sequential cohorts of participants; however, cohort 4 was not opened for enrollment.
