PEGPH20 Plus Nab-Paclitaxel Plus Gemcitabine Compared With Nab-Paclitaxel Plus Gemcitabine in Subjects With Stage IV Untreated Pancreatic Cancer

1. Phase 2, multicenter open-label randomized study with two run-in phases. The first
run-in phase was to evaluate safety and tolerability of PEGPH20 + Nab-paclitaxel +
Gemcitabine vs. Nab-paclitaxel + Gemcitabine. A second run-in phase was to evaluate a
new formulation of PEGPH20.

Phase 2 will be an open-label randomized study with same study drugs evaluating safety
and efficacy.

2. Subjects must have newly diagnosed stage 4 untreated metastatic pancreatic ductal cancer
diagnosed by a standard of Care CT scan within 20 days of dosing and meet all
inclusion/exclusion criteria.

3. Treatment consists of 4 week treatment cycles with Week 4 of every cycle, a wash-out
week. In Cycle 1, PEGPH20 will be administered twice per week with Nab-paclitaxel +
Gemcitabine given once/week 2-4 hrs after PEGPH20 and nab-paclitaxel + gemcitabine alone

4. Safety parameters include medical history, physical exams, adverse event and Concomitant
med collection, Doppler and CT scans for thromboembolic events, prophylactic enoxaparin,
Karnofsky Performance scale, Immunogenicity, Hematology, Chemistry, coagulation,
Weight/body surface area (BSA) for dosing, ECG and pharmacokinetics (PK) and Hyaluronan
(HA) catabolite levels. Efficacy parameters include standard of care CT scans, CA19-9,
tumor analysis of HA.

5. Subjects continue in study until disease progression, adverse event/toxicity, death or
either the subject/sponsor discontinues the study.

Key Inclusion Criteria:

- Signed Informed consent

- Histologically confirmed Stage IV pancreatic ductal adenocarcinoma w/ documented
disseminated neoplasm to liver and /or lung. Must have archival or fresh tissue (block
/slides) available pre-dose.

- One or more measurable metastatic tumors measurable on CT san per Response Evaluation
Criteria in Solid Tumors (RECIST v.1.1 ), excluding the primary lesion.

- No previous radiotherapy, surgery, chemotherapy or investigational therapy for the
treatment of metastatic disease.

- Karnofsky Performance Status >= 70%

- Life expectancy >= 3 mos

- Age >= 18 years

- Screen labs of Hemoglobin, platelets, absolute neutrophil count (ANC), bilirubin, AST,
ALT, serum creatinine, serum albumin, PT/INR, and PTT within specified values/criteria
per protocol prior to dosing.

Key Exclusion Criteria:

- Non metastatic pancreatic ductal adenocarcinoma

- Evidence of deep vein thrombosis (DVT) or pulmonary embolism (PE) or other known
thromboembolic event present during screening period.

- Known Central nervous system involvement, brain metastasis

- New York(NY) Heart Association Class III or IV cardiac disease or Myocardial
infarction within the past 12 months.

- History of another primary cancer within the last 3 years with the exception of
non-melanoma skin cancer, early state prostate cancer, or curatively-treated cervical
cancer in-situ.

- Contraindication to heparin as per NCCN guidelines

- Previous major bleed (bleeding requiring transfusion of red blood cells) on LMWH

- Any other disease, metabolic dysfunction, physical examination finding or clinical lab
finding that leads to reasonable suspicion of disease or condition that
contraindicates the use of an investigational drug, that may affect interpretation of
results, or render the subject at a high risk of treatment complications.
