Safety and Efficacy of Recombinant Human Thyroid Stimulating Hormone for Radioiodine 131I Treatment in Patients With Locally Advanced/Metastatic Differentiated Thyroid Cancer

Subjects: patients with postoperative local recurrent or metastatic differentiated thyroid cancer . Experimental group: Recombinant human thyroid stimulating hormone injection: 0.9mg/1.0mL/piece; intramuscular injection; once a day for two consecutive days. Control group: Thyroid hormone withdraw for 4-6 weeks. The two groups were treated with radioiodine 131I after plasma thyroid stimulating hormone elevated (>30mU/L). The efficacy and adverse reactions were observed.


Prospective, Single-centre, Feasibility Study to Evaluate the Use of 18F-PSMA PET/CT in Patients With Biochemically Active Medullary Thyroid Cancer

Rationale: In patients with medullary thyroid cancer (MTC), molecular imaging is used to assess the extent of disease in the primary diagnostic process and follow-up period to determine possible therapeutic options. The currently most used tracer in clinical practice, F-18 labelled fluorodeoxyglucose (18F-FDG), does not accurately detect MTC tumors with an indolent growth rate. A new, complimentary tracer is warranted to detect different subtypes. Objective: The primary objective is to assess the feasibility of using the F-18 labelled prostate specific membrane antigen (18F-PSMA) PET/CT for (re)staging patients with medullary thyroid cancer. The secondary objective is to compare the ability to detect MTC with the 18F-PSMA PET/CT to that of the 18F-FDG PET/CT. Study design: Prospective, single-centre, feasibility study. Study population: Patients (18 years of age or older) with biochemically and cytological/histological confirmed MTC, for whom the indication of an 18F-FDG PET/CT for tumor staging has already been determined on clinical grounds. Main study parameters/endpoints: The primary outcome of this study is the performance (lesion-based//patient-based sensitivity) of the 18F-PSMA PET to detect MTC lesions in patients with cytologically/histologically confirmed disease. Secondarily, the performance of the 18F-PSMA PET will be compared to the 18F-FDG PET/CT.


Diagnostic Significance of Single Center, Open and Prospective Evaluation of <Sup>18<Sup>F-FDG PET/CT Dynamic Imaging in Detecting Metastatic Central Lymph Nodes in Patients With Papillary Thyroid Cancer

The aim of this study is to make up for the gap by performing a dynamic scan of <Sup>18<Sup>F-FDG PET/CT on newly diagnosed patients with papillary thyroid carcinoma. Pathological and genomic studies are performed. The differences between metastatic central lymph nodes images and tissues are compared at the same time. <Sup>18<Sup>F-FDG PET/CT dynamic imaging is explored in metastatic central lymph nodes with papillary thyroid cancer for the diagnostic value.


An Open-Label, Non-Randomized, Dose Escalation, Single-Center, Investigator-Initiated Trial to Determine the Safety, Dosimetry, and Preliminary Effectiveness of 177Lu-DOTA-EB-FAPI in Metastatic Radioactive Iodine Refractory Thyroid Cancer Patients With Progressive Disease After Tyrosine Kinase Inhibitors Treatment

Increased fibroblast activation protein expression is positively correlated with the dedifferentiation and aggressiveness of thyroid cancer. Radiolabeled fibroblast activation protein inhibitor therapy, also known as radioligand therapy has become a novel treatment for patients with radioactive iodine refractory thyroid cancer and disease progression after first-line treatment. However, a major problem in the therapeutic use of 177Lu-DOTA-FAPI has been its short half-life and fast rate of clearance. This study was designed to evaluate the safety, tolerability, and maximum tolerated dose of a long-lasting radiolabeled fibroblast activation protein inhibitor 177Lu-DOTA-EB-FAPI in mRAIR-TC patients with PD after TKIs treatment.

Evaluation of F-18 Tetrafluoroborate (18F-TFB) PET/CT in Patients With Differentiated Thyroid Cancer

This phase II study evaluates F-18 tetrafluoroborate (18F-TFB) PET/CT scan in patients with differentiated thyroid cancer. Diagnostic imaging is necessary for planning treatment, monitoring therapy response, and identifying sites of recurrent or metastatic disease in differentiated thyroid cancer. 18F-TFB PET/CT may accurately detect recurrent and metastatic thyroid cancer lesions, with the potential to provide information for patient management that is better than the current standard of care imaging practices.


Phase I Investigator-initiated Clinical Trial in Patients With Differentiated Thyroid Cancer (Papillary Cancer, Follicular Cancer) by the Targeted Alpha Therapy Drug TAH-1005 ([211At] NaAt) (Alpha-T1 Study)

Single intravenous administration of TAH-1005 is performed in patients with differentiated thyroid cancer (papillary cancer, follicular cancer) who cannot obtain therapeutic effect with standard treatment or who have difficulty in implementing and continuing standard treatment. The safety, pharmacokinetics, absorbed dose, and efficacy will be evaluated to determine the recommended dose for Phase II clinical trial.


Restoration of Radioiodine Uptake With Selpercatinib in RET Fusion-Positive Radioiodine-Refractory Thyroid Cancer: A Phase 2 Study Performed in Collaboration With the International Thyroid Oncology Group (ITOG)

This research is being done to determine the efficacy of selpercatinib to restore radioactive iodine (I-131) uptake and allow for I-131 treatment in people with RET fusion-positive radioiodine-refractory thyroid cancer. This research study involves the study drug selpercatinib in combination with standard of care treatments, I-131 and thyrotropin alfa (rhTSH).


Multicentric Phase III Trial Comparing Two Strategies in Intermediate-risk Differentiated Thyroid Cancer Patients: Systematic Radioiodine Administration Versus Decision of Radioiodine Treatment Guided by a Post-operative Work-up Based on Serum Tg Values and Diagnostic RAI Scintigraphy

This trial is comparing two strategies in intermediate-risk differentiated thyroid cancer patients: Systematic radioiodine administration versus decision of radioiodine treatment guided by a post-operative work-up based on serum Tg values and diagnostic RAI scintigraphy


Evaluating the Clinical Value of 68Ga-TCR-FAPI PET/CT to Guide the Surgical Treatment for Medullary Thyroid Carcinoma (MTC)

Surgery remains the only curative option for MTC, yet the current imaging-based method (ultrasound, CT, MRI, 18F-FDG PET/CT) or calcitonin-based method are insufficient to map the extent of disease. In the previous studies, TCR-FAPI can covalently bind to FAP that increase tumor uptake and tumor retention, and better diagnosed MTC than the current radiotracers.
