Talimogene Laherparepvec in Patients With Unresectable Pancreatic Cancer

Completed · Phase 1

Conditions studied: Pancreatic Cancer

In brief

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.

• unresectable, locally advanced disease (isolated liver metastases are permitted)
• tumors of at least 1 cm diameter at screening
• measurable disease using Response Evaluation Criteria In Solid Tumors (RECIST) criteria
• failure of either standard therapy, OR any one of the following:
• no alternative therapeutic of higher curative potential is available;
• investigator determination that patient could not tolerate alternative therapeutic due to unacceptable toxicity; or,
• patient refusal to be treated with available alternative therapeutic
• age > 18 years
• life expectancy > 3 months
• adequate bone marrow function as indicated by:
• White blood cells (WBC) ≥ 3.0 x 10\^9/L
• platelets ≥ 100 x 10\^9/L
• hemoglobin ≥ 8.5 gm/dL
• adequate liver function as indicated by:
• bilirubin < 1.5 x upper limit of normal (ULN)
• alanine aminotransferase (ALT) or aspartate aminotransferase (AST) < 5 x ULN in case of presence of liver metastasis
• ALT or AST < 2.5 x ULN in case of absence of liver metastasis
• adequate renal function as indicated by a serum creatinine level < 1.5 x ULN.
• adequate hemostasis indicated by international normalized ratio (INR) ≤ 1.5
• mentally, physically and geographically able to undergo treatment and follow-up
• provided written informed consent
• first patient in each cohort only: seropositive for herpes simplex virus type 1 (HSV1)

You may not qualify if…

• history of other malignancy within two years prior to screening, except for prostate cancer (T1c, T2ab with definitive treatment, prostate-specific antigen (PSA) < 1 ng/ml, and without ongoing hormone suppression) or adequately treated in situ carcinoma of the cervix, basal cell carcinoma, or squamous cell carcinoma of the skin
• cystic form of pancreatic cancer; microcystic disease may be eligible upon discussion with Medical Monitor
• Common Terminology Criteria for Adverse Events (CTCAE) version 3 grade 2 or greater clinical pancreatitis within 8 weeks prior to dosing with OncoVEX\^GM-CSF
• other than metastases limited to the liver, imaging evidence of metastatic disease to any other organ or tissue
• any serious concomitant systemic disorder that would compromise the safety of the patient, at the discretion of the investigator
• evidence of compromised immune function including but not limited to:
• clinically significant absolute lymphocyte count < Lower Limit of Normal (LLN)
• known human immunodeficiency virus (HIV), acute or chronic active hepatitis B, or hepatitis C infection;
• concurrently taking HIV antiviral medications (e.g. protease inhibitors, azidothymidine, etc.)
• received intravenous (IV), intramuscular (IM) or subcutaneous (SC) human gamma globulin within 6 months prior to dosing with OncoVEX\^GM-CSF
• patients taking immunosuppressive agents (e.g. cyclosporine, tacrolimus, or oral or systemic corticosteroids at a dose of > 10 mg/day of prednisone or equivalent).
• pregnancy, lactation or lack of effective contraception in women of child-bearing potential (e.g., not post menopausal for > 2 years, or had tubal ligation); lack of effective contraception in men if the partner is of child-bearing potential; women must have been practicing an effective contraceptive method for at least three months prior to entry in to the trial (hormonal contraception or intrauterine device in conjunction with a barrier method); men must use a condom or be surgically sterilized
• patients with active bacterial or viral infections that require treatment with systemic antibiotics or antiviral agents within 2 weeks prior to the first dose of OncoVEX\^GM-CSF); (note: patients with active cold sores or other HSV1 infections must wait until those lesions have crusted over before receiving OncoVEX\^GM-CSF)
• surgery requiring general or spinal anesthesia within four weeks prior to dosing with OncoVEX\^GM-CSF
• Treatment with an investigational agent within 4 weeks prior to the first dose of OncoVEX\^GM-CSF
• serum carbohydrate antigen (CA)19.9 levels > 3000 U/mL at screening
• evidence of ascites on screening abdominal computed tomography (CT) scan
