PRIMARY OBJECTIVES: I. To assess the safety of modified leucovorin calcium, fluorouracil, irinotecan hydrochloride and oxaliplatin (mFOLFIRINOX) in combination with PEGPH20 and select the optimal dose of PEGPH20 for the phase II portion in patients with metastatic pancreatic adenocarcinoma.

PRIMARY OBJECTIVES: I. To assess the safety of modified leucovorin calcium, fluorouracil, irinotecan hydrochloride and oxaliplatin (mFOLFIRINOX) in combination with PEGPH20 and select the optimal dose of PEGPH20 for the phase II portion in patients with metastatic pancreatic adenocarcinoma. (Phase I) II. To assess the overall survival of patients with metastatic pancreatic adenocarcinoma treated with mFOLFIRINOX + PEGPH20 compared to those treated with mFOLFIRINOX alone. (Phase II) SECONDARY OBJECTIVES: I. To assess progression free survival (PFS) in patients receiving mFOLFIRINOX with PEGPH20 and patients receiving mFOLFIRINOX alone in this patient population. II. To assess objective tumor response (confirmed and unconfirmed, complete and partial) in patients with measurable disease treated with mFOLFIRINOX with PEGPH20 and patients receiving mFOLFIRINOX alone in this patient population. III. To determine the frequency, severity, and tolerability of adverse events of mFOLFIRINOX with PEGPH20. TERTIARY OBJECTIVES: I. To explore the correlation of maximum decrease in cancer antigen (CA) 19-9 levels and time to maximum decrease in CA 19-9 levels with overall survival, progression-free survival and response. II. To explore the correlation of plasma hyaluronan (HA) and tumor expression of HA with overall survival, progression-free survival and response. OUTLINE: This is a phase I, dose de-escalation study of pegylated recombinant human hyaluronidase followed by a randomized phase II study. PHASE I: Patients receive pegylated recombinant human hyaluronidase intravenously (IV) over 10 minutes on day 1*; oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours, and irinotecan hydrochloride IV over 1.5 hours on day 2; and fluorouracil IV over 46 hours on days 2-4. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity. PHASE II: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours, and irinotecan hydrochloride IV over 1.5 hours on day 2, and fluorouracil IV over 46 hours on days 2-4. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive pegylated recombinant human hyaluronidase IV over 10 minutes on day 1* and oxaliplatin, leucovorin calcium, irinotecan hydrochloride, and fluorouracil as in Arm I. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity. *NOTE: Some patients also receive pegylated recombinant human hyaluronidase on day 3 or 4 of courses 1 and 2. After completion of study treatment, patients are followed up for 3 years.
