NCT04381130 | NOT YET RECRUITING | Pancreatic Cancer

A Phase I/IIa Study of EF-009 in Patients with Pancreatic Cancer
Sponsor:

Everfront Biotech Co., Ltd.

Brief Summary:

This study is a multi center, open-label, dose escalation, Phase I/IIa study of EF-009 in up to 30 patients with borderline resectable and unresectable pancreatic cancer.

Condition or disease

Pancreatic Cancer

Intervention/treatment

EF-009

Phase

PHASE1

PHASE2

Detailed Description:

In Phase I, the study will follow a "3+3" design to determine the maximum tolerated dose (MTD) of EF-009 implanted surgically in patients with pancreatic cancer. The MTD is defined as one dose level (cohort) below the dose in which dose limiting toxicities (DLTs) were observed in ≥ 33% of the participants. Phase IIa is a single arm study with up to 12 subjects in order to test the hypothesis that the MTD of EF-009 will increase the overall survival (OS) and progression free survival (PFS) in patients with borderline resectable and unresectable pancreatic cancer. The number of EF-009 implanted will be based on the MTD dose determined in the Phase I portion of the study. In both the Phase I and Phase IIa portions of the study, subjects will be evaluated for response every 8 weeks after EF-009 wafer implantation for up to 2 years, by CT, PET/CT or MRI (per treating investigator's discretion) using the same method as at baseline. Tumor measurements will be assessed based on the Response Evaluation Criteria in Solid Tumors guidelines version 1.1 (RECIST v1.1). The total study duration for each subject consists of screening, treatment, and extended follow-up period and survival follow-up period.
