About this study

Official title: Irreversible Electroporation of Unresectable Liver Tumors - a Phase I Study of Safety and Feasibility

The aim of this study is to evaluate the safety and feasibility of curative intended irreversible electroporation (IRE) in the treatment of liver tumors neighboring major vessels or bile ducts.

Read the detailed description

Patients can be included in the study if they have one or more malignant liver tumors unsuitable for resection and thermal ablation (due to proximity of major vessels or bile duct) or other established liver directed therapies.

Prior to inclusion all potential participant will be evaluated by the local multidisciplinary team, to insure fulfillment of the above-mentioned criteria. In general, the included patient will have tumors with <1 cm of margin to major hepatic vessels or bile ducts, thereby not allowing for conventional treatments because of risk of i.e. hemorrhage, biliary tract damage, liver failure or ineffective ablation due to heat sink.

IRE will be done under general anesthesia as an in-patient procedure. Patients will be observed for at least 24 hours after IRE.

Patients will attend CT scans 1, 3, 6, 9, 12, 18, 24, 36, 48 and 60 months post-IRE according to national guidelines (for follow-up after radiofrequency ablation (RFA)). Patients will attend the out-patient clinic after 1, 3, 6, 9, 12, 18 and 24 months. During the follow-up period, patients will be asked to fill out electronic forms monitoring pain, quality of life and nutritional status. After 24 months the patients will only be followed with CT scans in accordance with the mentioned schedule. Data collection for scientific purposes will stop when the last included patient has been followed for at least 24 months or when the study period concludes.

In case of multiple liver tumors, where a conventional treatment approach is not possible due to a single lesion being too close to major vessels or bile ducts, IRE may be used in conjunction to conventional therapy.

What participants receive

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

  • Irreversible electroporationProcedure or surgery

    Also called NanoKnife(TM)

    The IRE procedure will be carried out as ultrasound guided technique either percutaneously or during laparotomy. Needle spacing and electrical pulse delivery will be performed in a standardized way.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 90-day complication rate and severity

    Adverse events will be registered and scaled according to the Clavien-Dindo classification.

    Measured: 90 days after intervention (last patient)

Secondary outcomes (9)
  1. Technical success rate

    The rate of patients were it is possible to place needles according to the treatment plan and deliver 90 electrical pulses per electrode pair

    Measured: 90 days after intervention (last patient)

  2. Technical efficacy rate (1 month) (according to SIR)

    The rate of patients showing no residual tumor on contrast enhanced computed tomography (ceCT)

    Measured: 90 days after intervention (last patient)

  3. Median local progression free survival from IRE

    The median time from the intervention to progressive disease of the treated lesion, according to RECIST 1.1 or modified RECIST (mRECIST) (only for HCC).

    Measured: 2 years after intervention (last patient)

  4. Median overall survival (OS) from IRE

    The median time from the intervention to death.

    Measured: 2 years after intervention (last patient)

  5. Longitudinal changes in perceived quality of life

    Quality of life questionnaire - Core 30 is used to assess the quality of life in the included patients. Raw scores will be calculated according to the manual. Items will be grouped in: Global health status (range 0 - 100, high is good), Functional scales (range 0 - 100, high is good) and symptom scales (range 0 - 100 low is good). Differences in each scales during the course of the trial will be calculated separately.

    Measured: 2 years after intervention (last patient)

  6. Longitudinal changes in pain perception

    Long term pain will be assessed using the modified Danish version of the Brief Pain Inventory - short form. The outcomes assessed will be an average score of pain severity items and interference items in accordance with the manual. The scales range from 0 to 10 (lower is less pain).

    Measured: 2 years after intervention (last patient)

  7. Periprocedural pain perception

    Perioperative pain will be scores using the visual analogue pain scale (range 0 - 10, low score is less pain).

    Measured: 90 days after intervention (last patient)

  8. Longitudinal changes in Eastern Cooperative Oncology Group (ECOG) performance status

    Physicians assessment of global functioning using the "Eastern Cooperative Oncology Group" performance status scale (range 0 - 5, low score is better)

    Measured: 2 years after intervention (last patient)

  9. Longitudinal changes in nutritional status assessment

    Nutritional status assessment using the Scored Patient-Generated Subjective Global Assessment (short form). The short form includes only patient reported measures and will be combined into a single score according to the manual (range 0 - 37, low score is better).

    Measured: 2 years after intervention (last patient)

Questions about this trial

What is this clinical trial studying?

A study testing Irreversible electroporation in people with Liver Metastases and Hepatocellular Carcinoma, run by Ole Thorlacius-Ussing, MD, DMSc, Professor of Surgery at 1 site in Denmark.

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 5 inclusion and 12 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: withdrawn, as of the sponsor's last update on 26 Mar 2021. 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 Denmark. 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 withdrawn before enrolling participants, so there are no results.

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?

90-day complication rate and severity (time frame: 90 days after intervention (last patient)). 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 26 Mar 2021.
