Inclusion criteria

  1. Have been informed of the nature of the study and provided written informed consent, prior to initiation of any study activities;
  2. Have an undiagnosed suspicious solid or mostly solid thyroid nodule.;
  3. 18 years of age or older at the time of consent;
  4. Are willing and able to complete all procedures and assessments in accordance with the clinical protocol; and,
  5. Have received recommendation for and are scheduled for an ultrasound guided FNAB, ultrasound guided core biopsy, excisional biopsy, lobectomy or complete thyroidectomy of at least one thyroid nodule.

Exclusion criteria

Exclusion Criteria:

  1. Are prisoners;
  2. Have a condition or impediment (i.e., insect bites, poison ivy, open sores, chafing of the skin, scar, tattoos, moles, etc.); that could interfere with the intended field of view (within one probe length or 4 cm of the nodule),

  5. Is pregnant;
  6. Have an acute or a chronic hematoma and/or acute ecchymosis of the thyroid;
  7. Is experiencing photo-toxicity or photo-sensitivity or is undergoing treatment for a photo-sensitive condition such as porphyria or lupus erythematosus;
  8. Patient has received chemotherapy for any type of cancer within 90 days from date of screening CDU;
  9. Have had previous image guided FNAB or surgical biopsy of the target nodule of interest within the 45 days of baseline Imagio Scan;
  10. Patient has participated in a clinical study of an investigational drug or device within 3 months prior to screening CDU that may have an impact on clinical outcomes; and,
  11. Patient has previously participated in this study.

What researchers measure

Primary outcomes

  1. Initial Assessment of Imagio's Ability to Distinguish Between Benign and Malignant Thyroid Nodules.

    The primary objective of this feasibility study is to provide an initial assessment of Imagio OA's ability to distinguish between benign and malignant thyroid nodules, and when appropriate, between benign and metastatic cervical lymph nodes in subjects.

    Time frame: 12-24 months

Results

Posted Jul 13, 2022
Limitations and caveats
The study was discontinued due to change in corporate strategy. This Early R\&D Development Study was terminated early due to change in corporate strategy. The reader portion of the study was not initiated per the protocol, therefore was no data generated for the primary and secondary endpoints to analyze.
