Study summary

The primary objective of this study is to reproduce in a multi-center study results obtained during the feasibility First-In-Human (FIH) study with Prof. Stefano Spiezia, MD (Ospedale del Mare, Naples, Italy) and to monitor additional thyroid-related symptoms and impact of patients quality of life post-ablation using a validated QoL questionnaire.

Read the detailed description

The study design is a prospective, non-randomized, clinical study using the Pulse Biosciences nPulse Vybrance Percutaneous Electrode (PE) System for the treatment of benign thyroid nodules (BTNs) using nanosecond Pulsed Field Ablation (PFA). All participants will receive at least one nsPFA treatment and may be eligible to receive a second treatment at the 6-month follow up visit per physician discretion. All participants will have regularly scheduled ultrasound assessments and administration of questionnaires (e.g., Thy-PRO39 and SF-12) at 1-month, 3 months, 6 months and 12 months post-nsPFA treatment.

Inclusion criteria

  • Participant is willing and able to provide voluntary, written to participate in this study and from whom written informed consent has been obtained
  • Participants must be willing and able to comply with study procedures including all follow-up visits
  • Selected nodule is amenable to trans-isthmus approach
  • Nodule is confirmed as benign based on results from one or more of the following diagnostic tests:

    1. (Bethesda II) on at least 2 ultrasound guided fine needle aspirations (FNA) or core needle (CNB);
    2. A single benign diagnosis of FNA or CNB when the nodule has benign ultrasound features [American College of Radiology (ACR) Thyroid Imaging Reporting \& Data System [TI-RAD] TR 1-3, American Thyroid Association [ATA] very low suspicion];
    3. Candidate has a hyperfunctional nodule following 1 ultrasound guided FNA or CNB with or without molecular testing; or
    4. Benign (Bethesda III or IV) with two biopsies in addition to molecular testing confirming benign diagnosis
  • Selected nodule is \<80.0 ml
  • Participant has normal vocal cord mobility by ultrasound evaluation
  • Participant has presence of compression symptoms, cosmetic concerns or anxiety for which participant requests treatment of the benign thyroid nodule
  • Participant has a solitary thyroid nodule or dominating nodule that is well-defined in multinodular goiter

Exclusion criteria

Exclusion Criteria:

  • Participant has an implantable electronic medical device. (i.e., pacemaker, implantable cardioverter defibrillator)
  • Participant has cystic nodules (\< 70% solid components)
  • Participant has calcified nodules
  • Participant is known to be immune compromised
  • Participant had previous neck irradiation
  • Participant has abnormal cervical lymph nodes present during screening visit examination
  • Participant has history of familial thyroid cancer in more than two first-degree relatives
  • Selected nodule previously treated with radiofrequency ablation or ethanol. This does not apply to nodules previously treated with nanosecond Pulsed Field Ablation (nsPFA)
  • Participants currently suffering from a hematological disease or bleeding tendency
  • Selected nodule likely to be in contact with the recurrent laryngeal nerve on ultrasound evaluation
  • Participant has a history of uncontrolled cardiac arrhythmia, uncontrolled hypertension, chronic liver disease or chronic kidney disease (Stage 4-5), or recent history of myocardial infarction or structural heart disease as determined by the Investigator
  • Participant has abnormal contralateral vocal cord function
  • Anesthesia drug allergies
  • Participant is pregnant at the time of screening or within 30 days prior to enrollment
  • Participant has any condition or situation which, in the Investigator's opinion, puts the participant at significant risk, could confound the study results, or may interfere significantly with the participant's participation in the study
  • Use of any device or drug within 30 days prior to enrollment that may confound the results of this study
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Study arms

  • Experimental
    nPulse Vybrance Percutaneous Electrode System Treatment Arm

    Adult participants who are clinically symptomatic will receive ablation of the benign thyroid nodule using the nPulse Vybrance Percutaneous Electrode System.

    Device: nPulse Vybrance Percutaneous Electrode System

Interventions

  • DevicenPulse Vybrance Percutaneous Electrode System

    The nPulse Vybrance procedure will be performed under ultrasonographic guidance using a local anesthetic at the intended puncture site and all participants will receive general anesthesia in the operating room. The targeted thyroid nodule will be treated within a customized treatment level (DEFAULT) programmed on the Console. The Investigator will treat the entire nodule while protecting from ablation to any surrounding vital structures to prevent serious adverse events throughout the procedure. Any procedural adverse events will be documented, as applicable.

ElapsedEstimatedEstimated, not yet reachedDate before it movedWhere the date was before it movedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2025 (actual). Primary completion is estimated for Apr 2027, 20 months after the start.

Of 71 interventional studies with no phase under Thyroid Nodule, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 46. This study's planned 20 months is below that.

Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 28, 2026: primary completion Jun 2026 → Apr 2027 and completion Jun 2027 → Oct 2027.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
