NCT ID: NCT03481920

Last Updated: 2019-08-22

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: EARLY_PHASE1
• Total Enrollment: 7 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-01-10
• Study Completion Date: 2019-06-10

Brief Summary

The purpose of this study is to evaluate the pharmacodynamics, safety and efficacy of PEGPH20 in combination with Avelumab in adult patients with chemotherapy resistant advanced or locally advanced pancreatic ductal adenocarcinoma (PDAC). This is a multi-center, open-label, non-randomized trial.

Detailed Description

The reported response rate with check-point inhibitors in PDAC is 0 %. This study tests the hypothesis that elimination of HA in pancreas tumor microenvironment mediated by PEG PH20 will result in increased tumor vascularization and vessel patency as well as stromal remodeling with increase immune infiltrate. These effects may facilitate the activity of check-point inhibitors like avelumab by at least two mechanisms including increase in drug delivery and increasing immune infiltrate.

Study Groups

PEGPH20 + Avelumab

PEGPH20, a multi-site PEGylated enzyme generated by conjugating N-hydroxysuccinimidyl ester of methoxypoly(ethylene glycol)-butanoic acid (MSBA30K/B or PEG) and recombinant human hyaluronidase (rHuPH20). PEGPH20 has a half-life of approximately 2 days, thereby enabling systemic activity and sustained duration of action to degrade HA. In many different tumor types tested in murine xenograft models, response to PEGPH20 has been shown to be more robust for tumors characterized by higher HA expression.

Group Type: EXPERIMENTAL

PEGylated Recombinant Human Hyaluronidase (PEGPH20)

Intervention Type: DRUG

PEGPH20 will be administered at a dose of 3.0 micrograms per kilogram (μg/kg) as an intravenous (IV) infusion.

Avelumab

Intervention Type: DRUG

Avelumab will be administered as at a dose of 10 milligrams per kilogram (mg/kg) as an intravenous (IV) infusion once every 2 weeks.
