Purpose

This randomized phase II trial studies how well fluorouracil, irinotecan hydrochloride, and oxaliplatin (combination chemotherapy) works and compares to gemcitabine hydrochloride and paclitaxel albumin-stabilized nanoparticle formulation before surgery in treating patients with pancreatic cancer that can be removed by surgery. Drugs used in chemotherapy, such as fluorouracil, irinotecan hydrochloride, oxaliplatin, gemcitabine hydrochloride, and paclitaxel albumin-stabilized nanoparticle formulation, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known whether combination chemotherapy is more effective than gemcitabine hydrochloride and paclitaxel albumin-stabilized nanoparticle formulation before surgery in treating pancreatic cancer.

      • NCCN Intermediate Risk is defined as having at least one of the following: PSA 10-20 ng/ml, Gleason score =7, T2b-T2c
      • High Risk with a single high risk feature is defined as having only one of the following: PSA>20 ng/ml, Gleason score 8-10, or T3a
      • Excluded are those in the following risk groups: Low risk; High risk with more than 1 high risk factor; Locally advanced/very high risk=T3b-T4; Metastatic: N1 or M1

Exclusion Criteria

    ude:

    • Liver disease, including known cirrhosis or active hepatitis
    • Patients on systemic corticosteroids (>10mg prednisone per day) or other immunosuppressive drugs
    • Known HIV+ patients
    • Regional lymph node involvement or distant metastases
    • Patients planning to receive whole pelvic irradiation
    • Prior treatment for prostate cancer, except TURP or ADT. For ADT, it may only be given for a maximum of 6 months

    ProstAtak®

    		Aglatimagene besadenovec (CAN-2409) + valacyclovir + radiation therapy +/- ADT
  • Biological: Aglatimagene besadenovec + valacyclovir

    Patients will receive three courses of ProstAtak® each consisting of aglatimagene besadenovec injection + oral valacyclovir. AdV-tk injection will be delivered to the prostate via trans-rectal ultrasound guided injection as follows: The first injection will be given at least 15 days and not more than 8 weeks before starting radiation. The second injection will be 0-3 days before initiation of radiation therapy. The third injection will be 15-22 days after the 2nd injection. The prodrug, valacyclovir, will be administered at a fixed dose for 14 days after each AdV-tk injection. Standard external beam radiation therapy will be delivered to the prostate. Short-term androgen deprivation therapy (maximum of 6 months) is optional but must be decided before enrollment to allow for stratification.
