Active clinical trials for "Thyroid Diseases"

The goal of this retrospective study is to compare the safety and efficiacy of endoscopic thyroidectomy via retro-auricular single-site approach, transoral endoscopic thyroidectomy vestibular approach and transareola approach.

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).

Phase 1/2, multicenter, multiple dose clinical study designed to evaluate lonigutamab in subjects with TED.

150 adults patients with locally advanced or metastatic BRAFV600E mutation-positive, differentiated thyroid carcinoma who are refractory to radioactive iodine and have progressed following prior VEGFR targeted therapy will enter in the trial. Patients will be randomized in a 2:1 ratio to either dabrafenib plus trametinib or placebo. Patients will be stratified by number of prior VEGFR targeted therapy (1versus2) and prior lenvatinib treatment (yes versus no)

This study was conducted in patients with differentiated thyroid cancer who had undergone total/near-total thyroidectomy. After surgery patients were randomized to one of two methods of performing thyroid remnant ablation. One group of patients who took thyroid hormone medicine and were euthyroid [i.e. their thyroid stimulating hormone (TSH) levels are normal], and received injections of rhTSH (0.9 mg daily on two consecutive days) followed by oral radioiodine. The second group of patients did not take thyroid hormone medicine so that they were hypothyroid (i.e. their TSH levels were high), and were given oral radioiodine.

The goal of this study is to evaluate combined radioactive iodine (RAI, 131-I) and external beam radiotherapy (XRT) to optimize the radiation dose delivered to treat well differentiated thyroid cancers (DTC) with iodine-avid metastases. The investigators hypothesize that precise dosimetric planning will permit this combined RAI-XRT radiotherapeutic approach to be safe and permit higher tumor radiation doses than could otherwise be delivered. Patients with metastatic well-differentiated DTC) that is not completely resectable with macroscopic invasion of tumor into cervical soft tissues and/or non-resectable distant metastases, are the target study population. The primary objective is to evaluate safety as defined by the incidence of maximum grade 3 or greater NCI CTCAE toxicity observed during the treatment period and for the first 30 days following completion of radiotherapy. Secondary endpoints will evaluate efficacy at 6 months and feasibility of this combination to deliver a minimum cumulative dose of 80 Gy to the index tumors selected prior to treatment initiation. The investigators plan to enroll 48 subjects at an accrual rate of 1 subject per month over a study duration of 4 years.

The aim of this study is to test the hypothesis that the quality of recovery with topical lidocaine is better than placebo.

The primary objective of this clinical trial is to assess the safety and tolerability of sub-tenon aflibercept in combination with either saline or hyaluronidase (HA) in patients with acute Thyroid Eye Disease (TED) as assessed by the incidence and severity of adverse events from baseline to day 45. Participants will undergo clinical examinations and receive three injections of aflibercept with saline, aflibercept with hyaluronidase, or hyaluronidase.

Open label randomized controlled study, for Harmonic versus Ligasure in transoral endoscopic thyroid surgery.

The aim of the study was to evaluate the effectiveness of combination therapy with dabrafenib and trametinib (anti-BRAF and anti-MEK inhibitors) in the neoadjuvant treatment of BRAF-positive anaplastic thyroid cancer. The prognosis in patients with ATC is poor due to the rapid and invasive tumor growth and the rapid development of metastases. Dabrafenib is an antineoplastic agent, a selective RAF kinase inhibitor that competes with ATP. Oncogenic substitutions of the amino acid valine at position 600 (V600) BRAF lead to constitutive activation of the RAS / RAF / MEK / ERK pathway and stimulation of tumor cell growth. Trametinib is a reversible, highly selective, allosteric inhibitor of the activation of mitogen-activated, extracellular signal-regulated kinases 1 (MEK1) and 2 (MEK2). Dabrafenib and trametinib inhibit two kinases in the signaling pathway, BRAF, and MEK. The combination of the two drugs provides effective inhibition of proliferative signal conduction. The investigators hypothesize that the combination treatment with these two drugs - dabrafenib and trametinib - can improve the response rate in the neoadjuvant mode in ATC without significant regimen-limiting toxicity and with better follow-up locoregional control.
