Brief Summary:

Phase 1B: Open label (all patients receive PEGPH20+gemcitabine), dose escalation, safety and tolerability study to determine the safe dose of PEGPH20 to use in combination with gemcitabine in Stage IV previously untreated pancreatic cancer patients.

Phase 2: Randomized, double blind study to compare the effect of overall survival of gemcitabine plus PEGPH20 vs gemcitabine plus placebo in Stage IV previously untreated pancreatic cancer patients.

Condition or disease Intervention/treatment Phase
Stage IV Pancreatic Cancer Drug: Gemcitabine Drug: PEGPH20+ gemcitabine Phase 1 Phase 2

Detailed Description:

PEGPH20 is a PEGylated version of human recombinant PH20 hyaluronidase that, in preclinical studies, has been shown to remove HA from the extracellular matrix surrounding tumor cells by depolymerizing this substrate. 87% of pancreatic ductal adenocarcinomas (PDA) overexpress HA. PDA tumor tissue may be especially sensitive to the HA-degradation properties of PEGPH20 and thus more responsive to the cytotoxic effects of a given dose of gemcitabine. Modifying the extracellular environment to increase the penetration and efficacy of anti-cancer agents represents a novel approach to treating pancreatic cancer and may provide important therapeutic outcomes in patients with Stage IV Previously Untreated Pancreatic Cancer.

This Phase 1B/2 study will assess safety, tolerability, treatment effect, and various PK/PD endpoints.

Arm Intervention/treatment
Active Comparator: Gemcitabine
Gemcitabine + Placebo
Drug: Gemcitabine
1000 mg/m2 given IV one time a week (Cycle 1: 7 weeks on treatment, 1 week off treatment; Cycle 2+: 3 Weeks on treatment, 1 week off treatment)
Other Name: Gemzar
Experimental: PEGPH20
Drug: PEGPH20+ gemcitabine
(Cycle 1: 7 weeks on treatment/1 week off treatment; Cycle 2+: 3 Weeks on treatment/1 week off treatment). Doses start at 1.0 mcg/kg and modified until recommended Phase 2 dose is determined. Gemcitabine given at 1000mg/m2. Treatment continues until occurrence of significant treatment-related toxicity, progressive disease, or discontinuation criteria are met
Other Name: PEGylated Recombinant Human Hyaluronidase

Primary Outcome Measures :
  1. To determine the safe dose of PEGPH20 in combination with the approved dose of gemcitabine. [ Time Frame: 1 year ]
    The safety and tolerability profile of PEGPH20 used in combination with gemcitabine will be assessed.

  2. To compare the effect of overall survival between treatment groups. [ Time Frame: 2 years ]
    To compare the effect of overall survival of gemcitabine plus PEGPH20 vs gemcitabine plus placebo in Stage IV previously untreated pancreatic cancer patients.

Secondary Outcome Measures :
  1. To characterize plasma PK of PEGPH20 when used in combination with gemcitabine [ Time Frame: Multiple visits and timepoints for the duration of the study ]
    Evaluation of plasma PK

  2. Assess the ORR by RECIST 1.1 criteria [ Time Frame: 1 year ]
  3. Assess PEGPH20 PD activities including HA catabolites in serum and urine, HA staining changes in tumor biopsies, as well as PEGPH20 effect on vascular perfusion and metabolic activities of the tumor using DCE MRI and FDG PET [ Time Frame: 1 year ]
  4. Explore the PEGPH20 effect on CA19-9 changes in relation to: 1. Intensity of tumor-associated HA staining 2. DCE-MRI perfusion, and/or 3. FDG-PEG/CT perfusion, anatomic data and metabolic activity [ Time Frame: 1 year ]
