Active clinical trials for "Thyroid Diseases"

The investigational drug, VRDN-001, is a monoclonal antibody that inhibits the activity of a cell surface receptor called insulin-like growth factor-1 receptor (IGF-1R). Inhibition of IGF-1R may help to reduce the inflammation and associated tissue swelling that occurs in patients with thyroid eye disease (TED). This clinical trial will evaluate the safety, tolerability and pharmacokinetics (the concentration of drug in the blood over time) of VRDN-001 in healthy volunteers and in patients with TED. Study participants with TED will also be evaluated over time for changes in their signs and symptoms of TED compared to their baseline measurements.

The goal of this clinical trial is to demonstrate that TIR3A nodules with negative genetic test can be safely and effectively treated by radiofrequency ablation, with nodular shrinkage and improvement of clinical symptoms. Fine needle aspiration cytology is the gold standard test for differential diagnosis of thyroid nodules, but sometimes the result can be indeterminate with a risk of malignancy of 10-30%. In these cases the ablation is not indicated and many patients with benign nodules that may benefit from the procedure are not treated. All the patients enrolled must have a TIR3A cytology and negative genetic test for mutations associated with thyroid carcinoma. Before the ablation blood, evaluation of serum TSH, anti-thyroglobulin antibodies, anti-thyroid peroxidase antibodies and calcitonin levels will be performed.

This study is an open-label phase 2 study to evaluate the safety and efficacy of Nivolumab plus Lenvatinib in patients with unresectable anaplastic thyroid cancer.

The purpose of this study is to evaluate the efficacy and safety of PD-1 inhibitor and anlotinib combined with multimodal radiotherapy for the second-line treatment of recurrent or metastatic anaplastic thyroid cancer.

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.

Anaplastic thyroid cancer (ATC) is an almost invariable lethal cancer in humans. Most patients present with a rapid progressive mass in the neck with progressive complaints like dyspnoea, dysphagia or pain. The risk of suffocation is the main reason for rapid surgical intervention, but we know from literature that an oncological resection with clear margins is seldomly achieved. Some patients deteriorate that fast after surgery that radiation therapy and/or chemotherapy is not feasible anymore. Patients with BRAF-mutated ATC already have shown to benefit from targeted BRAF/MEK inhibition. This study aims to increase the number of patients that undergo a successful R0 tumor resection after neo-adjuvant BRAF/MEK inhibitor treatment.

Papillary thyroid carcinoma (PTC) is the most common thyroid cancer and has a good prognosis.According to the 2015 American thyroid association (ATA) guidelines, no gross extrathyroidal extension and the number of pathological lymph node micrometastases (<0.2cm) ≤5 were defined as the low recurrence risk group. After total thyroidectomy and radioiodine treatment, the probability of disease-free status (irritant Tg<1ng/ml, no evidence of other disease recurrence) is about 78%-91%, and the probability of structural recurrence is about 1%-10%. In recent years, due to the further understanding of PTC, surgeons tend to become more conservative in treatment, such as active observation or reducing the extent of surgery. The indication for lobectomy has been extended to tumors <4cm without extrathyroidal extension and clinical lymph node metastasis. For patients treated with lobectomy, current guidelines recommend that Thyroid Stimulating Hormone (TSH) be controlled at 0.5-2 mU/L, but evidence on the prognostic benefits of this TSH inhibition range is lacking.In recent years, a number of studies have suggested that if postoperative TSH in low-risk patients after lobectomy is acceptable within the reference range, it means that a considerable number of patients have a high probability of not receiving thyroxine replacement therapy after surgery, which can significantly improve their quality of life.A previous retrospective study from our institute showed no significant association between TSH levels after lobectomy and prognosis.The aim of this study was to evaluate the benefits and risks of postoperative TSH levels within the reference range (0.4-5 mU/L) in patients with low-risk papillary thyroid cancer who underwent lobectomy.In order to improve the effect of longer recurrence and death time of PTC, the investigators also performed postoperative thyroglobulin and its antibody for short-term treatment response evaluation.

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.

Thyroid nodules are a common clinical problem. Epidemiologic studies have shown the prevalence of palpable thyroid nodules to be approximately 5% in women and 1% in men living in iodine-sufficient parts of the world and up to 30% in iodine deficient regions, such as Germany. The clinical importance of thyroid nodules rests with the need to exclude thyroid cancer which occurs in 5-15%. Differentiated thyroid cancer (DTC), which includes papillary and follicular cancer, comprises the vast majority (90%) of all thyroid cancers. In Germany, approximately 7,000 new cases will be diagnosed in 2011. The yearly incidence has increased from 3.6 per 100,000 in 1973 to 8.7 per 100,000 in 2002, and this trend appears to be continuing. Recurrence-free survival is generally excellent and depends on the risk group. The role of postoperative remnant radioiodine ablation (RRIA) as the most serious question regarding the initial management of DTC still needs to be resolved even after decades of radioiodine use. American Thyroid Association directions for future research addressing these questions include: Better understanding of the long-term risks of radioiodine use; Improved risk stratification; Randomized controlled trials are still missing in which RRIA has proven its worth as a safe and very effective treatment that results in an improved life expectancy and a reduced recurrence rate. Many observational studies lack sufficiently high evidence. Evidence grade is rated mainly on "expert level", based on non-randomized retrospective observation studies. Although RRIA in Europe is established as adjuvant standard treatment for all patients with DTC, except those with stage T1a, it remains to be shown throughout if it is beneficial for low risk and medium risk patients without metastases (M0), also known as stage I patients according to UICC/AJCC classification, accounting for 40-90% of all patients. Blood doses due to cumulative radioiodine therapy may well exceed 2 Gy, and RRIA induces an average blood dose of 0.28 Gy to the entire body. Risks as estimated from that dose are not insignificant. The question is whether or not the condition after remnant ablation justifies such an increased risk of a secondary malignancy. The probability of causation for a pharyngeal or breast tumour can well exceed the margin of a 50% after being exposed to RRIA or consecutive I-131 diagnostic imaging to explore measureable Tg levels. Even though radioiodine therapy can benefit some patients with advanced thyroid carcinoma, it is still unknown whether the risks of RRIA outweigh any discernable benefit. Undoubtedly, quality of life may be affected by adjuvant use of I-131. Study Hypothesis: The I-124 study arm may have considerable benefits for the patient included in the study. These include enhanced tumour and risk stratification, avoidance of unnecessary I-131 exposure in 30-89 percent of patients who were classified with "low risk" tumour (MACIS or AMES scoring) or "stage I disease" (UICC-AJCC TNM staging system), and, improved quality of life at the same or better morbidity and mortality rates in the I-124 arm. Environmental and hospital staff related benefits include prevention or saving of I-131 exposure. This study is designed to compare effectiveness of treatments following and evaluating guideline recommendations in two assignment arms.

The treatment of Papillary Thyroid Microcarcinoma (PTMC) nowadays varies among physicians, surgeons and radiologist. The recently published articles show that the prognosis of PTMC by different means of treatment strategies tends to be good. But multicentered, randomized, parallel and prospective study is rare. RFA is the abbreviation of "Radiofrequency Ablation", which tends to be an alternative strategy except conventional surgery. The investigator aims to confirm whether RFA for treating PTMC braces same effectiveness and prognosis comparing with conventional surgery. Besides, this trial also investigates the safety, economy and psychological quality under different treatments.
