Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
