Study summary

This study is a prospective, multi-center, single-arm study of pediatric subjects (age 3-12) with Sleep-Disordered Breathing ("SDB") due to adeno-tonsillar hypertrophy which are treated with the ENTire IRE System.

Subjects will be followed for six (6) months post-treatment. The objective of the study is to provide an ongoing safety and effectiveness assessment of the ENTire IRE System in treating pediatric adeno-tonsillar hypertrophy.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients are 3-12 years of age.
  • Tonsillar hypertrophy of grade 2 or more on the Brodsky Grading System for Tonsils ("BGST").
  • Children with SDB scheduled for adeno-tonsillar surgery after an otolaryngology evaluation.

Exclusion criteria

Exclusion Criteria:

  1. Patients with a pacemaker, cochlear or similar electro stimulator implants.
  2. Patients for whom the anesthesia involves high risk.
  3. Significant illness (e.g., cancer, severe disease, neurological disease, severe heart disease).
  4. Craniofacial anomalies.
  5. Patients which underwent prior tonsillectomy or tonsillotomy.
  6. Epilepsy or other conditions involving convulsions.
  7. Parent/Guardian inability to give and to complete reported questionnaires.
  8. Any other reason the investigator deems the subject is unfit for participation in the study.
Terms in these criteria, in plain language(2)

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.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

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.

Study arms

  • Experimental
    Enlarged tonsil(s) and/or adenoid mass will be reduced by ENTire IRE System.

    Device: Irreversible Electroporation

Interventions

  • DeviceIrreversible Electroporation

    The bi-polar IRE System locally applies short, high-voltage (HV) pulses, increasing the permeability of tissue cells, creating non-thermal irreversible electroporation (NTIRE). The energy is transferred via bipolar forceps handpiece causing irreversible cell membrane perforation and apoptosis resulting in tissue reduction. The clinical effect is anticipated within 2 to 4 weeks post-treatment.

What researchers measure

Primary outcomes

  1. Number of Participants With Device- or Procedure-Related Adverse Events (Bleeding, Readmission, Dehydration, or Emergency Department Visit)

    Evaluation of the following device and/or procedure-related events: bleeding, readmission, dehydration and emergency department visits.

    Time frame: 6 months

  2. Time From Treatment to First Wong-Baker FACES Pain Scale Score of 2 or Below

    For each participant, the number of days from treatment until the first daily pain score of 2 or below on the Wong-Baker FACES® Pain Scale. Pain is assessed after treatment and then daily for the first 7 days post-procedure. The scale ranges from 0 ("No hurt") to 10 ("Hurts worst"). Minimum value is 0 and maximum value is 10; higher scores indicate more pain (a worse outcome).

    Time frame: From procedure until the end of the first week post procedure (7 days)

  3. Change From Baseline in OSA-18 Total Score at 3 Months

    The Obstructive Sleep Apnea-18 (OSA-18) questionnaire is completed by the parent or caregiver at baseline and at 3 months post treatment. The outcome is the change in OSA-18 total score from baseline to 3 months. The questionnaire has 18 questions, each rated from 1 ("None of the time") to 7 ("All of the time"). The total score ranges from 18 (minimum) to 126 (maximum); higher scores indicate more severe symptoms and greater impairment (a worse outcome). No formal hypothesis will be tested.

    Time frame: 3 months post treatment

  4. Change From Baseline in OSA-18 Total Score at 6 Months

    The Obstructive Sleep Apnea-18 (OSA-18) questionnaire is completed by the parent or caregiver at baseline and at 6 months post treatment. The outcome is the change in OSA-18 total score from baseline to 6 months. The questionnaire has 18 questions, each rated from 1 ("None of the time") to 7 ("All of the time"). The total score ranges from 18 (minimum) to 126 (maximum); higher scores indicate more severe symptoms and greater impairment (a worse outcome). No formal hypothesis will be tested.

    Time frame: 6 months post treatment

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar 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

Start is estimated for Nov 2026; primary completion for May 2028, 18 months later.

Of 78 interventional studies with no phase under Hypertrophy, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 22. This study's planned 18 months is above that.

How these figures are worked out, and which studies are left out of them.

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.
