Brief Summary

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

Pancreas as well as Cholangiocarcinoma have a dismal prognosis at time of diagnosis, due to late onset of clinical symptoms, patients present with advance disease. Complete surgical resection is the only potential curative treatment, however only a small percentage is eligible for upfront total surgical resection due to extension into anatomical related important vascular structures. Neoadjuvant chemo(radio)therapy has become the standard treatment modality for non-primary resectable disease (borderline resectable and locally advanced pancreatic cancer (LAPC)), where subsequent downstaging can make identification of the primary tumor more challenging during surgery. Near-infrared (NIR) fluorescence imaging can aid surgeons by providing real-time visualization of tumors, suspect lymph nodes and vital structures during surgery. Additional intra-operative feedback could possibly reduce the frequency of positive resection margins and increase complete removal of locally spread tumor and involved lymph nodes and could thereby improve patient outcomes as well as overall survival. cRGD-ZW800-1 is a targeted NIR-fluorophore, with specific binding capacity for integrins (αvβ3, αvβ5, αvβ6) which are overexpressed on tumor cells and tumor-associated vascular endothelium associated with neoangiogenesis.

Detailed Description

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

Pancreatic cancer is one of the most common causes of death in the United States. With a median survival of less than 6 months, the prognosis is very poor. After diagnosis, the 1 and 5-year survival rates are around 25% and 10%, respectively. Surgical resection is the only curative treatment, but also results in relatively low survival and present recurrence risk, depending on the stage. In the same order of magnitude, bile duct cancer is also found, it can be classified according to location within or outside the liver, extrahepatic bile duct tumors are much anatomically related to pancreatic tumors, surgical treatment is therefore often the same: (partial) pancreatic resection. During surgery, it is difficult to distinguish between malignant and benign tissue, especially if patients have been treated neoadjuvantly. Currently, near-infrared fluorescence imaging is a technique with great potential to illuminate important structures during surgery. Fluorescent substances can be injected intravenously, which then specifically attach to malignant cells or tumor-associated structures, such as stroma or blood vessels, and emit light in the near-infrared spectrum (700-900 nm). Thus, with specially equipped camera systems, tumors literally light up and the surgeon can completely remove the tumors during surgery in real time. cRGD-ZW800-1 is a newly developed fluorescent agent, which binds to integrins, which are associated with neoangiogenesis, and has the potential to make tumor cells in the pancreas more visible during surgery in order to achieve more complete surgical (R0) resections.

Aims of the study:

* To assess the feasibility, safety and tolerability of cRGD-ZW800-1 for the visualization of pancreatic carcinomas, perihilar or distal cholangiocarcinomas and if present associated metastatic lymph nodes and their distant metastases in real-time using specific NIR fluorescence imaging systems.
* Determining the optimal dose and dose interval of a single intravenous bolus injection of cRGD-ZW800-1 for intraoperative NIR imaging

Study design:

Open label, dose-ranging and optimal dose-(interval) selection study, with a two-factorial design. In total 20 patients diagnosed with a malignant tumor of the pancreas, or distal/hilar bile ducts, which are eligible for surgical resection with or without neoadjuvant treatment will be enrolled. These patients will be distributed over four dosing-, and one expansion cohort: Cohort 1 (0.05mg/kg, 2-4h before intervention), Cohort 2 (0.05mg/kg, 14-24h before intervention), Cohort 3 (0.025mg/kg, 2-4h before intervention), Cohort 4 (0.025mg/kg, 14-24h before intervention) and Cohort 5 (expansion cohort). Patients are included if they met the inclusion/exclusion criteria and will be screened during pre-operative work-up for surgery.

Study population: Patients with or without neoadjuvant treatment eligible for surgical resection at the Leiden University Medical Center (LUMC) of histologically proven malignant tumors of the pancreas head, neck and tail. As well as patients with histologically proven tumors of the peri-hilar and distal bile ducts (extrahepatic cholangiocarcinomas) with or without neoadjuvant treatment.

Intervention: Single bolus injection of cRGD-ZW800-1 2-24h before surgery. Intra-operative in-vivo assessment of NIR-fluorescence of tumor, lymph nodes, possible distant metastasis and anatomical related structures. After resection ex-vivo assessment of NIR-fluorescence of all resected tissue, on gross-macroscopy, bread loafs and microscopic slides.

Investigational drug: Intravenous single bolus injection of the targeted NIR fluorophore cRGD-ZW800-1. This targeted 800nm zwitterionic fluorophore developed by the Hospital Pharmacy Department of LUMC consists of the fluorophore ZW800-1 conjugated to the cRGD peptide.

Imaging: Intraoperative imaging will be performed with at least one of the following CE-marked near-infrared (NIR) fluorescence imaging systems: Quest Spectrum imaging platform (v2/3.0) for open-procedures, the Olympus or Karl-Storz system for the diagnostic laparoscopy or the Intuitive Surgical Da Vinci Xi (Firefly-mode) for minimally invasive robot-assisted procedures. With a NIR-imaging system a potential fluorescent signal of the tumor can be evaluated. Furthermore, the Quest Spectrum platform will also be used for evaluation of ex-vivo fluorescence of resected tissue on the back table (Back table imaging) and pathology department (ex-vivo imaging), which shall be performed during and after every procedure.
