About

This phase I/II trial studies the side effects and best dose of panitumumab-IRDye800 and to see how well it works in finding cancer in patients with pancreatic cancer who are undergoing surgery. Panitumumab-IRDye800 is a combination of the antibody drug panitumumab and IRDye800CW, an investigational dye that can be seen using a special camera. Panitumumab-IRDye800 may attach to tumor cells and make them more visible during surgery in patients with pancreatic cancer.

Full description

PRIMARY OBJECTIVES:

I. To determine the optimal dose of panitumumab-IRDye800 in identifying pancreatic cancer compared to surrounding normal tissue in the ex vivo setting as measured by tumor to background ratio.

SECONDARY OBJECTIVES:

I. Determine the safety and tolerability of the panitumumab-IRDye800 as an imaging agent in subjects undergoing resection of pancreatic cancer.

II. Determine whether metastatic lesions, positive lymph node, or residual disease can be detected by near-infrared (NIR) fluorescence imaging with panitumumab-IRDye800 but not by white light.

OUTLINE: This is a phase I, dose-escalation study of panitumumab-IRDye800 followed by a phase II study.

Patients receive a loading dose of panitumumab intravenously (IV) over 60 minutes, and after 15 minutes of observation, patients then receive panitumumab-IRDye800 IV over 60 minutes on day 0. Patients then undergo surgical resection 2-5 days after panitumumab-IRDye800 administration with imaging using the Novadaq SPY/LUNA, Novadaq IR9000 fluorescence imaging system with open field handheld fluorescence imaging camera, and/or pinpoint endoscopic fluorescence imaging camera, and SurgVision Explorer Air multi spectral fluorescence reflectance system.

After completion of study treatment, patients are followed up at 15 and 30 days.

27 participants in 5 patient groups

Cohort 1a

Experimental group

Description:

A test/loading dose of 100 mg of unlabeled Panitumumab (fixed dose) will be administered via a 60 minute IV infusion prior to infusion of the Panitumumab IRDye800. Cohort 1a will receive 25 mg of Panitumumab IRDye800 with a 100 mg unlabeled test/loading dose of Panitumumab. The surgical resection will then occur 2 to 5 days after infusion. Intraoperative imaging will be performed using the intraoperative optical imaging devices

Treatment:

Biological: Panitumumab

Drug: Panitumumab-IRDye800

Procedure: Fluorescence Imaging

Cohort 1b

Description:

Cohort 1b will receive 50 mg of Panitumumab IRDye800 with a 100 mg unlabeled test/loading dose of Panitumumab. A test/loading dose of 100 mg of unlabeled Panitumumab (fixed dose) will be administered via a 60 minute IV infusion prior to infusion of the Panitumumab IRDye800. The surgical resection will then occur 2 to 5 days after infusion. Intraoperative imaging will be performed using the intraoperative optical imaging devices

Treatment:

Biological: Panitumumab

Drug: Panitumumab-IRDye800
