Brief Summary:
The purpose of this study is to compare the efficacy and safety of PEGylated Recombinant Human Hyaluronidase (PEGPH20) combined with nab-paclitaxel plus gemcitabine (PAG treatment), compared with placebo combined with nab-paclitaxel plus gemcitabine (AG treatment), in participants with hyaluronan (HA)-high Stage IV previously untreated pancreatic ductal adenocarcinoma (PDA).

Condition or disease Intervention/treatment Phase
Pancreatic Ductal Carcinoma Other: Biological: PEGylated Recombinant Human Hyaluronidase (PEGPH20) Drug: Placebo Drug: nab-Paclitaxel Drug: Gemcitabine Phase 3

Detailed Description:
Participants will be randomized in a 2:1 ratio to PAG or AG treatment. If the final analysis supports a positive benefit-risk assessment for PEGPH20, participants in the PAG arm post-final analysis will be offered the option to continue PAG treatment if the Investigator deems it in their best interest. Participants in the AG arm post-final analysis will be offered the option to switch to and continue on PAG treatment. Participants in the AG arm post-final analysis who choose not to switch to PAG treatment will be discontinued from the study. These participants will be treated according to the Investigator's discretion and local standard-of-care. Participants continuing PAG treatment and participants switched from AG to PAG treatment post-final analysis will enter long-term follow-up after treatment discontinuation. All participants who have discontinued either PAG or AG treatment and are in long-term follow-up will continue to be followed up until the participant dies, is lost to follow-up, or withdraws consent.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion criteria:

Participants must satisfy all the following inclusion criteria to be enrolled in the study:

  1. Signed, written Institutional Review Board/Ethics Committee-approved Informed Consent Form (ICF).
  2. Stage IV PDA with histological or cytological confirmation of PDA.
  3. Participants must be determined to be HA-high based on archived or fresh tumor core biopsy or sample obtained after the participant has documented metastatic disease. Biopsies/samples must meet the following requirements:

    1. Pancreas tumor biopsies/samples obtained on or after the date that metastatic disease is documented or tumor biopsies/samples from a metastatic lesion are acceptable.
    2. Tumor biopsies or samples must meet the requirements provided in the Study Laboratory Manual with regard to tumor tissue architecture. Note: cytology samples from fine needle aspirates without maintained tissue architecture or brushing biopsies are not acceptable.
    3. Tumor tissue (formalin-fixed paraffin-embedded [FFPE] block preferred) must include enough tumor to make a minimum of 5-10 unstained, consecutive FFPE slides (10 slides are preferred) of 1 archival block that meet specific tissue sample requirements.
  4. Radiographic confirmation of Stage IV PDA with at least 1 tumor metastasis measurable on computed tomography (CT) scan or magnetic resonance imaging (MRI) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria, excluding the primary pancreatic lesion.
  5. If a participant has had adjuvant/neoadjuvant therapy and/or therapy for locally advanced disease (chemotherapy for non-metastatic pancreatic cancer in combination with or without radiation therapy), tumor recurrence or disease progression must have occurred no sooner than 6 months after completing the last dose of the aforementioned therapies, provided all toxicities have returned to baseline or less than or equal to (≤) Grade 1.

Highly effective contraceptive methods consist of prior sterilization, intrauterine device (IUD), intrauterine hormone-releasing system (IUS), oral or injectable contraceptives, barrier methods, and/or true sexual abstinence.

Exclusion criteria:

Participants are ineligible for enrollment if they meet any of the following exclusion criteria:

  1. Clinical evidence of deep vein thrombosis (DVT), pulmonary embolism (PE) or other known thromboembolic (TE) event present during the screening period.

    1. Participants with superficial vein thrombosis are eligible.
    2. Participants with visceral/splanchnic vein thrombosis are still eligible if, in the opinion of the Investigator, the visceral/splanchnic vein thrombosis is primarily associated with the anatomic location of the underlying disease of metastatic pancreatic cancer (there must be primary or metastatic disease in reasonable proximity to the thrombosis, and the Investigator determines that the thrombosis is due to a local tumor event and not a coagulation issue).
  2. Previous radiotherapy, surgery, chemotherapy, or investigational therapy for the treatment of metastatic disease.

    a. Palliative radiotherapy for pain control of metastatic bone lesions is allowed.

  3. Known central nervous system involvement or brain metastases.
  4. New York Heart Association Class III or IV cardiac disease or myocardial infarction within the past 12 months.

  14. Any other disease, active, uncontrolled bacterial, viral or fungal infection requiring systemic therapy, metabolic dysfunction, physical examination finding or clinical laboratory finding that leads to reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug, or that may affect the interpretation of the results, or that may render the participant at high risk for treatment complications.
  15. Immunization with a live vaccine up to 2 weeks prior to Day 1.
  16. Hypersensitivity to the active substance or ingredients of PEGPH20, gemcitabine, and nab-paclitaxel.
  17. Inability to comply with study and follow-up procedures as judged by the Investigator.
