Trial Information

Detectable Early Increase in Blood Flow (EIBS) in the Duodenum in Patients With Pancreatic Cancer

The overall goal of this study is to test a technique that in the future may allow
endoscopic detection of pancreatic neoplasia. The study is a single group, prospective,
open label pilot study designed to assess the feasibility and efficacy of 4D-ELF in
detecting EIBS in peri-ampullary duodenal mucosa in pancreatic cancer patients compared to
control patients. The expected duration of subject participation, and a description of the
sequence and duration of all trial periods, including follow-up is complete after the
initial evaluation.

Inclusion Criteria:

- Age 18 years or older.

- Informed written consent.

- Patient scheduled for previously planned EUS or ERCP.

- Patients with known adenocarcinoma of the pancreas.

Exclusion Criteria:

- Presence of conditions not allowing biopsy or FNA if clinically indicated (e.g.
coagulation disorder).

- Significant family history of pancreatic cancer.

- Patients with other tumors of the pancreas or duodenum (i.e neuroendocrine tumors,
carcinoid, GIST, known familial polyposis syndrome (FAP, HNPCC, Juvenile polyposis,

- Patient with premalignant lesions (duodenal adenoma, IPMN).

- Active duodenitis/ulcer from any cause (peptic, H pylori etc).

- Patients with known chronic pancreatitis will be excluded from study group (not
control group however).

- Know pregnancy or sexually active females of childbearing age who are not practicing
an accepted form of birth control.

Type of Study:


Study Design:

Allocation: Non-Randomized, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic

Outcome Measure:

To investigate whether EIBS measurements from pancreatic cancer will be elevated when measured in the peri-ampullary duodenal mucosa, in comparison to the same measures from control patients undergoing upper endoscopy without know pancreatic cancer.

Outcome Time Frame:

Completion of Study Procedure (EUS)
