Study Overview

PEGPH20 Plus Gemcitabine With Radiotherapy in Patients With Localized, Unresectable Pancreatic Cancer

This is a single arm phase II trial assessing the potential activity of combination PEGPH20 plus Gemcitabine with radiotherapy in ten patients with localized, unresectable pancreatic adenocarcinoma.

This is a pilot trial evaluating the safety and potential efficacy of PEGylated Recombinant Human Hyaluronidase (PEGPH20) plus concurrent Gemcitabine and radiotherapy. Recognizing that PEGPH20 has not been previously delivered with radiotherapy but is unlikely to contribute to increased toxicities, this trial will have an abbreviated sequential dose escalation schema for the first three patients. PEGPH20 will be given twice per week for the first 28 days and then weekly for another 2 weeks during radiotherapy. Gemcitabine will be delivered weekly at the first day of radiotherapy and continued weekly, per published literature. Patients will remain on study for three months. The duration of active treatment with PEGPH20 and Gemcitabine plus radiotherapy will continue for 5-6 weeks. Efficacy outcome will occur 6-8 weeks after the completion of radiotherapy.

  • Pancreatic Adenocarcinoma Non-resectable
  • DRUG: PEGylated Recombinant Human Hyaluronidase (PEGPH20)
  • DRUG: Gemcitabine
  • RADIATION: Radiation

Primary Outcome MeasuresMeasure DescriptionTime Frame
Number of Participants with Treatment Related Adverse Events (AEs)Adverse events will be assessed weekly, from Day1 Treatment through up to 8 weeks after the end of treatment. Safety will be assessed during the study by evaluation of AEs, clinical safety laboratory tests (hematology, blood chemistry (including C-reactive protein [CRP]), coagulation, urinalysis, and PEGPH20 immunogenicity), vital signs, 12-lead ECGs, and physical examinations. The severity of AEs will be graded by Investigators using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03Up to 8 Weeks After the End of Treatment
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Overall Tumor Response RateCT Chest/Abdomen/Pelvis will be completed at End of Study Visit. End of Study visit will be done 6-8 weeks after the last day of radiotherapy. The evaluation of overall lesion response will be a composite of the target lesion response, non-target lesion response and presence of new lesions, per RECIST 1.1 criteria.Change from Baseline through 8 Weeks After End of Radiation Therapy
Conversion to Resectability RateNumber of enrolled subjects completing at least 2 weeks of PEGPH20 plus concurrent gemcitabine and radiotherapy who meet institutional surgical criteria for surgical resectability, as determined by End of Study CT imaging. End of Study CT imaging will be done up to 8 weeks after the end of radiation therapy.Up to 8 Weeks After End of Radiation Therapy
