About this study

The objectives of this study are to study the safety and effect of IRE as a treatment for inoperable hepatic and pancreatic malignancy.

Read the detailed description

Irreversible electroporation (IRE) is a form of non-thermal local ablation for solid tumors, it induces apoptosis of tumor cells by creating irreversible damage in the cell membrane using electric current. The use of thermal ablation for tumors adjacent to major blood vessels is not advisable because the "heat-sink effect" owing to blood vessels render the thermal treatment not effective. On the other hand, application of thermal ablation to a tumor adjacent to blood vessels or bile ducts will cause thermal damage to these structures. It has been shown in animal experiments that IRE is effective in causing cell death while blood vessels, bile ducts, and nerves in the vicinity are preserved. Early evidence of clinical studies has shown that IRE is a reasonably safe and effective treatment for pancreatic and hepatic tumors.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • IRE treatmentProcedure or surgery

    The treatment procedure is carried out percutaneously under ultrasound or CT guidance, or using laparoscopic or laparotomy approach when the lesion is close to hollow viscera or abdominal wall, with the patient under general anaesthesia. Insulated needle electrodes, will be placed in the treatment areas under ultrasound or CT guidance. The tumor lesion is identified, measured, and located by ultrasound or CT. Electrical current is administered in pulses with electrocardiographic synchronization to reduce the risk of cardiac arrhythmia.

IRE treatmentOtherIrreversible electroporation (IRE) is a form of non-thermal local ablation for solid tumors, it induces apoptosis of tumor cells by creating irreversible damage in the cell membrane using electric current. IRE treatment is given for a therapeutic purpose as a non-surgical alternative to those patients with an inoperable condition.

Questions about this trial

What is this clinical trial studying?

A study testing IRE treatment and Ultrasound in people with Hepatic Malignant Tumors and Pancreatic Cancer, run by Chinese University of Hong Kong at 1 site in Hong Kong.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 22 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 21 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: poor case accural). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Radiological assessment (time frame: 1 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Oct 2022.
