Electrochemotherapy of Posterior Resection Surface for Lowering Disease Recurrence Rate in Pancreatic Cancer (PanECT Study)

Phase 1TerminatedNCT04281290

University Medical Centre Ljubljana3 enrolled

Overview

The aim of the study is to evaluate toxicity and effectiveness of electrochemotherapy (ECT) with bleomycin in pancreatic cancer in clinical study phase I and II. After surgical resection of pancreatic cancer, the posterior resection surface will be treated with ECT with the intention to lower disease recurrence rate. The study will include 20 patients in phase I clinical study and additional 20 patients in phase II clinical study (or in the extension of the clinical study), which will fulfill inclusion criteria. Treatment effectiveness will be evaluated by US or CT imaging, to detect early local recurrence of the disease. Long term effectiveness of the treatment will be evaluated by frequent and precise patient follow-up. During follow-up clinical examination, laboratory tests, tumor markers (Ca 19-9 and CEA) and US/CT imaging will be performed. The secondary objectives of the trial are to quantify the impact of the treatment on the patient's quality of life, tolerance to the therapy and suitability for larger study to be conducted.

The study will be conducted on patients with resectable pancreatic cancer. 20 patients will be included in phase I clinical study and additional 20 patients in phase II clinical study (or in the extension of the clinical study). After surgical resection of pancreatic cancer, the posterior resection surface will be treated with purpose to lower disease recurrence rate. Plate electrodes will be used for ECT treatment, the electrodes will be placed between choledochal cut-end, truncus celiacus, remaining of the pancreas and aortal lymph nodes. ECT will be performed within 8-28 min after intravenous in bolus administration of bleomycin (15 mg/m2). Triggering of electric pulses will be synchronized with ECG signals, through the ECG triggering device AccuSync to avoid delivery of pulses in vulnerable period of the heart. All patients will be treated after the procedure has been thoroughly described to them and have signed informed consent.

Interventions

Electrochemotherapy - electroporation with Cliniporator Vitae® and chemotherapy drug Bleomycin PHC 15 e. (United States Pharmacopeia - USP)PROCEDURE

Procedure: Electrochemotherapy Exploration, anesthesia, pancreatic cancer resection, bleomycin administration, electroporation, formation of all anastomoses. Device: Cliniporator Vitae® Positioning of plate electrodes according to landmarks, 8-28 min after administration of bleomycin application of electric pulses (8 pulses, duration 100 microseconds, frequency 8 Hz with amplitude adequate to cover the whole treated lesion with electric field necessary for reversible plasma membrane permeabilization, approximately 1000V/cm), removal of electrodes. The maximum duration of procedure is 90 minutes, after liver mobilization. Drug: Bleomycin PHC 15 e. (United States Pharmacopeia - USP) Intravenous bolus administration of bleomycin (15 mg/m2)

Outcomes

Primary Outcomes

Evaluation of feasibility and safety

Every patient will be closely followed-up after operation with clinical examination and blood tests (hemogram, comprehensive metabolic panel, liver panel) according to the study protocol (day 1, 3, 7 after operation). In case of detected abnormalities additional imaging (US and/or CT) will take place. Findings will be noted and reported in line with Clavien-Dindo classification of surgical complications. The primary measure is to detect complications after surgery and to determine whether the complication is related to electrochemotherapy treatment or not.

Time frame: 7 days after operation

Secondary Outcomes

Disease-free Survival

Disease-free survival is defined as the amount of time a subject survives without disease recurrence after treatment. Recurrence is defined as significant elevation of tumor markers Ca19-9 and CEA after operation (normal value of Ca19-9 is under 37.0 kU/L, normal value of CEA is under 4.2 µg/L). The appearance of one or more lesions on imaging investigation (US and/or CT) is also considered a recurrence. The tumor markers and imaging investigations will be performed according to study protocol (tumor markers 1, 3, 6, 12 and 24 months after operation; imaging 1, 3, 6, 12, 18 and 24 months after operation - the imaging method will be CT or MR with or without contrast, with the exception of 1 and 18 months after the operation when an US will be performed).

Time frame: 1, 3, 6, 12, 18 and 24 months after operation

Overall Survival

Overall survival is defined as the amount of time a subject survives after therapy. Patient enrolled in the study will be followed up for at least five years. During first two years after surgery follow-up will be as written above, after that period patient will be followed-up according every 6 months.

Time frame: From the time of surgical treatment until 5 years after surgery
