Use of the EnLightTM and LightPathTM Imaging Systems in Gastrointestinal Tumour Surgery (CLIO)

25. januar 2017 oppdatert av: Lightpoint Medical Limited

Evaluation of the Use of Intra-operative Molecular Imaging With BetaScope and in Vitro Measurement With LightPath Specimen Analyser Devices in Gastrointestinal Tumour Surgery

This study will evaluate the performance of the EnLightTM and LightPathTM Imaging Systems in detecting tumour lesions in patients with gastric, pancreas, bile duct or duodenal cancer.

EnLightTM will be used to detect positron emission and the LightPathTM system to detect Cerenkov Luminescence. Both are emitted by the Positron Emission Tomography (PET) agent.

The study will also evaluate the patient safety and radiation safety of the EnLightTM, and the safety for the device operators and surgical staff of the LightPathTM Imaging System.

Studieoversikt

Detaljert beskrivelse

This is a pilot study that is prospective, open-label, single-centre in nature in patients with gastric, pancreas, bile duct or duodenal cancer in whom tumour excision surgery is indicated.

Patients who give written informed consent will be screened for the study (Visit 1). Patients will undergo a positron emission tomography (PET) whole body scan. Screening assessments, including the PET scan, must be performed no less than 60 days before surgery and may be performed on the day of surgery.

On the day of surgery (Visit 2), subject's blood glucose level will be measured. Subjects with a blood glucose level < 12 mmol/l will receive an intravenous injection of 2-5 Mega Becquerel/kg (MBq/kg), up to a maximum 300 MBq of fluorine-18 fluorodeoxyglucose (18F-FDG) prior to surgery.

During surgery and not less than 120 minutes after injection of FDG, the primary lesion will be imaged using the EnLightTM system to determine margin status.

Gastrointestinal tumour excision surgery will then be performed according to standard of care. The surgical cavity and the lymph nodes will be imaged by the EnLightTM system to establish whether other radioactive tissue remain. These results will not influence any surgical or clinical decision-making, which will remain as standard of care. The resected tumour excision specimen will be imaged by the LightPathTM Imaging System. The resected tumour excision specimen will, in addition, be analysed according to standard of care pathology. The surgeon and surgical staff will be monitored for external exposure to ionizing radiation by means of dosimeters, and position sensors during surgery.

Patients will be followed-up (Visit 3) within a 2 - 14 day window after the end of surgery for adverse events (AEs). Those related to the use of the investigational devices, or the PET imaging agent will be identified as such.

EnLightTM and LightPathTM Imaging Systems arm

Patients will first be injected intravenously with 2-5 MBq/kg, up to a maximum 300 MBq of the marketed product 18F-fluorodeoxyglucose (FDG) and after this undergo tumour excision surgery according to standard of care.

The surgical cavity will be imaged by the EnLightTM system and the tumour excision specimen will be imaged by both the EnLightTM and LightPathTM Imaging Systems. The EnLightTM and LightPathTM Imaging Systems results will not influence any surgical or clinical decision-making. The tumour excision specimen will be analysed according to standard of care pathology. Patients will be followed-up (Visit 3) 2-14 days after the end of surgery for adverse events (AEs).

The FDG is injected at least 120 minutes prior to the imaging by the EnLightTM and LightPathTM Imaging Systems

Tidsramme
The location of PET imaging agent as measured by beta particle detection
Tidsramme: Intraoperatively (during the single session of surgery on Day 0)
The EnLightTM will be used for determining the number of lesions, their location and margin status, in the surgical cavity including within surrounding tissue, and lymph nodes. The EnLightTM is a beta particle detector used for imaging the location of the PET imaging agent. It works both in a hot-spot mode, to localise areas with high beta particle detection signal from the PET imaging agent, and in an imaging mode that allows video imaging of areas where the PET imaging agent has accumulated.
