Study summary

Multi-center registry study to evaluate disease-related quality of life outcomes of thyroid embolization via pressure-enabled delivery (PED-TAE). Additional technical success data on parenchymal volume reduction, thyroid function tests changes and post-procedural complications will be recorded. Data will be collected for patients who have undergone PED-TAE using the TriNav Infusion System at participating sites. The registry study will include up to 10 sites, with Sarasota Memorial Health Care System acting as the lead site responsible for maintaining and monitoring the study database.

Study population

Patients that may be included in the registry study are those who have undergone PED-TAE using TriNav at the selected study sites. Data will be collected on patients meeting eligibility criteria.

Study subjects will not be informed of their inclusion in this registry dataset, and the results of this research will not be reported to study subjects at the conclusion of the study.

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

  1. Adults, 18 years and or older and 89 years or younger
  2. Having undergone PED-TAE using the TriNav Infusion System
  3. Meeting one of the following criteria:

    1. Documented subclinical and or clinical hyperthyroidism in the presence of a toxic multinodular goiter or a toxic nodule > 20 ml
    2. Patients' ineligible or refusing surgery, radio-iodine therapy or percutaneous ablation
    3. Non-functioning multinodular goiters or nodule causing compressive symptoms including but not limited to neck pain, dysphagia, stridor, exercise induced dyspnea and/or pressure symptoms
    4. Bethesda category 2-3 (benign, or atypia or follicular lesion of undetermined significance) on 2 separate fine-needle aspiration (FNAB) results with a benign molecular profile with patient declining surgical resection

Exclusion criteria

Exclusion Criteria:

  1. Renal insufficiency
  2. Unable to tolerate angiography including pregnancy and severe allergy to contrast media
  3. Bethesda 4-6 on FNAB (suspicious for follicular neoplasm, suspicious for , or malignant)
  4. \<18 years old or >89 years old
  5. Graves' disease or inflammatory thyroiditis (Hashimoto's) or other condition with the presence of an extensive collateral network as demonstrated or initial angiography
  6. Presence of a bovine arch or any other anatomical variant with no inferior thyroid artery present
  7. Prior thyroid thermal ablation
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.

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Groups and cohorts

  • Patients who have undergone PED-TAE using the TriNav Infusion System at participating study sites.

    Subjects with planned PED-TAE delivered via TriNav will receive their treatment following routine standard of care procedures. Post-procedural data obtained by a patient chart review will be collected in a study database. No additional study-specific interventions or visits outside of the routine clinical treatment will be performed.

What researchers measure

Primary outcomes

  1. ThyPro-39 questionnaire

    Change in quality of life as measured by ThyPro-39 questionnaire at 6-months (+/- 60). Responses to each statement are measured on a Likert scale ranging from '0= no symptoms or problems' to '4= severe symptoms or problems' based on the period of the last 4 weeks. Higher scores indicate greater impact on quality of life due to thyroid issues.

    Time frame: 6 months

  2. Procedure related adverse events

    Safety as measured by the rate of procedure related adverse events as measured by SIR criteria at 2-weeks (+/- 7 days), 3- (+/- 30 days) and 6-months (+/- 60 days) post PED-TAE using TriNav treatment.

    Time frame: 6 months

Secondary outcomes

  1. Thyroid volume change

    Thyroid volume change based on 3D CT volumetry at 6-months (+/- 60 days) post-treatment

    Time frame: 6 months

  2. Change in TSH, T3 and T4

    Change in TSH, T3 and T4 levels at 2-weeks (+/- 7 days), 3-(+/- 30 days) and 6-months (+/- 60 days) post-treatment

    Time frame: 6 months

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

Started Apr 2025 (actual). Primary completion is estimated for Apr 2027, 24 months after the start.

Of 20 observational studies under Hyperthyroidism, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 48. This study's planned 24 months is below 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.
