Treatment Groups

This trial involves 3 different treatments. 68-Gallium-DOTATATE-PET/CT is the primary treatment being studied. Participants will be divided into 3 treatment groups. There is no placebo group. The treatments being tested are in Phase 2 and have already been tested with other people.

Experimental Group 1
Experimental Group 2
Experimental Group 3


This trial is for patients born any sex aged 18 and older. There are 4 eligibility criteria to participate in this trial as listed below.

Inclusion & Exclusion Checklist
Mark “yes” if the following statements are true for you:

Measurement Requirements

This trial is evaluating whether 68-Gallium-DOTATATE-PET/CT will improve 1 primary outcome and 2 secondary outcomes in patients with Thyroid Diseases. Measurement will happen over the course of During baseline assessment.

Prevalence of patients with metastatic RAI-non-avid or RAI-non-responsive thyroid cancer whose tumors are characterized by a high SSTR2 expression by imaging with 68Ga-DOTATATE PET/CT
Prevalence of thyroid cancer patients characterized by a high SSTR2 expression in at least one metastatic lesion per patient documented by SUVmax of 68Ga-DOTATATE-PET/CT of above 15 among patients with metastatic HTC, DTC and MTC.
Maximum standard uptake value (SUVmax) of 68Ga-DOTATATE
SUVmax will be compared in groups based on the somatic mutation status in primary tumors: BRAF-like, RAS-like, harboring mitochondrial DNA mutations and /or RET protooncogene mutation.
Correlation between tumor volume and SUV max for each participant
Tumor volume in cm3 as measured by the ellipsoid formula will be measured on up to 10 lesions per organ and correlated with SUVMax

Patient Q & A Section

Please Note: These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What does 68-gallium-dotatate-pet/ct usually treat?

There was no significant difference between the performance of DOTA PET/CT and the optimal therapy. A good correlation between clinical and pretreatment imaging findings was observed.

Anonymous Patient Answer

What are the signs of thyroid diseases?

This highlights the necessity of a multidisciplinary approach and the importance of the physician's awareness of the patient's personal history of endocrine diseases and comorbidities.

Anonymous Patient Answer

What are common treatments for thyroid diseases?

The most commonly used medications are thyroxine, liothyronine, propylthiouracil, and methimazole. These can be found by searching for clinical trials in the database using the specific condition, medication, and site of interest.

Anonymous Patient Answer

How serious can thyroid diseases be?

Thyroid disease can cause a number of health problems due to an imbalance between production of thyroxine (T4) and triiodothyronine (T3). Symptoms such as lethargy, weight gain, heat intolerance, palpitations and irritability can occur. The underlying cause may be an autoimmune thyroid disease, a tumour or medications used for hyperthyroidism. Patients should be questioned about their symptoms and history of exposure to radiation.

What is the average age someone gets thyroid diseases?

Thyroid diseases are relatively common. Female patients have a higher prevalence of Hashimoto's thyroiditis, while male patients have more frequently Graves' disease and multinodular goitre. Male patients also had higher TG levels than female patients. Age of onset of thyroid diseases is different between genders, with females being diagnosed at an earlier age (19.4±9.4 years) compared with males (23.6±11.8 years). Gender differences in thyroid disorders are not apparent prior to puberty, but become evident after puberty.

What is thyroid diseases?

Thyroid disease is a common disorder worldwide, which has become more prevalent in recent years because of increasing rates of obesity and type 2 diabetes, and increasing prevalence of autoimmune thyroid diseases. The differential diagnosis of nodular thyroid diseases includes Hashimoto's thyroiditis, Graves' disease, and subacute thyroiditis. The clinical presentation of thyroid disease varies widely depending on the underlying etiology. In addition, the terminology and classification of thyroid disorders vary greatly between countries. These differences make it challenging to understand and communicate the medical knowledge among clinicians and researchers across different countries.

What is the latest research for thyroid diseases?

Thyroid disorders continue to be prevalent among adolescents and young adults. As we learn more about the disorder, new treatments, drugs and procedures appear. Many are available today such as radioiodine therapy, radioactive iodine uptake assay and thyroid scanning. The challenge for researchers continues to be developing effective, safe and cost effective treatments.\n

Have there been other clinical trials involving 68-gallium-dotatate-pet/ct?

Findings from a recent study showed that 108 scintigraphically negative patients were treated for 72 weeks, after which time only four of them demonstrated biochemical evidence of disease progression, while all of the remaining 100 patients remained clinically free of disease. Findings from a recent study suggest the efficacy of DOTA-PET/CT in detecting metastatic thyroid cancer.

Anonymous Patient Answer

What causes thyroid diseases?

The main cause of thyroid disease is not related to the presence of iodine deficiency. Compensatory hyperthyroidism can occur when there is an excessive production of thyroid hormones (thyroxine or triiodothyronine), which occurs if the pituitary gland produces more thyroid-stimulating hormone. This may happen due to genetic factors or irritable bowel syndrome. Thyrotoxicosis may also occur when the body does not produce enough thyroid hormone because the thyroid gland has been damaged by radiation or inflammation, or because it is not producing enough thyroid stimulating hormone. Low thyroid levels are usually caused by Hashimoto's thyroiditis, a chronic autoimmune disorder where the body attacks its own thyroid tissue.

What are the common side effects of 68-gallium-dotatate-pet/ct?

Side effects were not uncommon in our study population. Most of the side effects we reported were mild to moderate and self-limited. There were no cases of life-threatening side effects. The risk of serious side effects was low. While our data suggest that 68-Ga-DOTA PET/CT may be associated with an increased risk of mild to moderate adverse events, all cases of serious adverse events reported were also mild or moderate. Therefore, we recommend caution when considering this diagnostic modality in cases of suspected malignancy.
