Trial summary

In order to secure the diagnosis of lung cancer, the investigator will perform a bronchoscopy in order to take tissue samples. These samples will be analyzed in the pathology. This is the routine standard. The aim of the study is to treat the lesion with a device that works both with cold and radiofrequency. Read more about this study

About this study

In order to secure the diagnosis of lung cancer, the investigator will perform a bronchoscopy in order to take tissue samples. These samples will be analyzed in the pathology. This is the routine standard. The aim of the study is to treat the lesion with a device that works both with cold and radiofrequency. The device is already in use for the treatment of lesions. The device allows direct treatment of the lesion during the routine bronchoscopy. As planned, the lesion will then be surgically removed. After the surgery the lesion will be analyzed in the pathology to show the effect of the use of the device. This additional treatment is safe and will support the treatment of the lesion. There are no additional steps or assessments for the participants to undergo.

What is being measured

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

  1. Successful device use, defined as the completion of ablation with the HybridTherm® system with investigator confirmation that the ablation zone achieved sufficient coverage based on intra-procedural imaging.

    Measured: during procedure

Secondary outcomes (6)
  1. Safety outcomes, with a specific focus on bleeding events, graded according to the Nashville Bleeding Scale, and the occurrence of other adverse events as documented in the medical record.

    Nashville Bleeding Scale Grade Findings at Bronchoscopy Rationale

    1. Suctioning of blood required for less than 1 minute Minimal bleeding of no clinical consequence to the patient or the provider
    2. Suctioning more than 1 minute, or repeat wedging of the bronchoscope for persistent bleeding, or instillation of cold saline, diluted vasoactive agents, or thrombin Requires tools to control or prevent further bleeding
    3. Selective intubation with endotracheal tube (ETT) or balloon/bronchial blocker for < 20 minutes, or premature interruption of the procedure Short-term but clinically meaningful change requiring more invasive intervention and procedure interruption
    4. Persistent selective intubation > 20 minutes, or ICU admission, or PRBC transfusion, or need for bronchial artery embolization or resuscitation Indicates serious deterioration, requiring escalation of care and advanced ventilatory and hemodynamic support

    Measured: up to 6 - 7 weeks post procedure

  2. Macroscopic and microscopic evidence of ablation in the resected specimen, assessed using standard histopathological methods (H&E staining).

    Measured: within 24 hours after procedure

  3. Visual estimation of histopathologic ablation completeness, defined as the estimated percentage of tumor necrosis within the ablation zone, as determined by routine pathology reporting.

    Measured: within 24 hours after procedure

  4. Evaluation of macroscopic and microscopic necrosis within the ablation zone (histopathologic complete response hpCR), defined as the absence of viable tumor cells within the ablated area, if reported as part of routine histological assessment.

    Measured: within24 hours after procedure

  5. Descriptive intra-procedural metrics, recorded during the bronchoscopy procedure: Total ablation time; Number of cryoRFA activations; Electrical parameters of energy delivered during the procedure; Number of probe repositioning within the lesion

    total ablation time will be recorded in minutes; number of cryoRFA activations will be recorded in energy applications;

    Measured: day 0

  6. Estimated ablation zone size (mm), derived from intraoperative CBCT, routinely obtained during the procedure.

    Measured: day 0

Questions about this trial

What is this clinical trial studying?

A study testing Cryotherapy in people with NSCLC and Cryotherapy, run by Elisabethinen Hospital at 1 site in Austria.

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 6 inclusion and 8 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: opening soon, as of the sponsor's last update on 15 Apr 2026. 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 Austria. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Adrienne Seil (0043 732 7676 4492, adrienne.seil@ordensklinikum.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Successful device use, defined as the completion of ablation with the HybridTherm® system with investigator confirmation that the ablation zone achieved sufficient coverage based on intra-procedural imaging. (time frame: during procedure). 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 15 Apr 2026.
