Filter by:This is A non-blinded trial. Oral radioiodine was given 24 hours after the second injection of rhTSH, and scanning was done 48 hours after the radioiodine administration. Each patient was scanned first following rhTSH and then scanned after thyroid hormone withdrawal.
Phase I/II Clinical Trial of Dose-tolerance, Pharmacokinetics and Iodine Uptake Effects For Recombinant Human Thyroid Stimulating Hormone In Post-thyroidectomized Patients
This trial is a prospective, non-interventional, monocentric study aiming to collect standard of care imaging of patients treated with Iodine-131 for the determination of dosimetric studies. Data from this study will be collected as part of an European research project called MEDIRAD. The overall objectives of this project are to enhance the scientific bases and clinical practice of radiation protection in the medical field, and more specifically to develop and implement the tools necessary to establish the range of absorbed doses delivered to healthy organs in patients undergoing thyroid ablation and the threshold absorbed dose required for thyroid ablation. This will enable patient specific treatment planning that will minimize risk to the patient while ensuring a successful outcome and will facilitate development of a large scale epidemiological study of the effect of low absorbed doses from irradiation of normal organs with internal sources of radionuclides. Patients will be followed as part of their standard of care. Imaging (SPECT/CT (Single Photon Emission Computed Tomography-Computerized Tomography) and Whole Body scintigraphy) performed at 48 hours post Iodine-131 treatment will be collected. Measures of external gamma radiation will also be collected in the European database.
Description of the role of a post-operative external beam radiotherapy in patients with differentiated thyroid cancer.
This is a pilot study designed to evaluate the cutaneous effect of systemic inhibition of the tyrosine kinase pathway in the presence or absence of solar simulated light exposure. A maximum of 45 subjects will be accrued into the overall study we anticipate approximately 25 patients in the Raf inhibitor group and 10 patients each into the Tyrosine Kinase and MEK inhibitor arms of the study.
Donafenib for advanced 131I-refractory/resistant differentiated thyroid cancer(DTC).
Postmenopausal women with differentiated thyroid cancer (DTC) taking suppressive doses of levothyroxine (L-T4) are thought to have accelerated bone loss and increased risk of osteoporosis. Therefore, the investigators try to investigate the effects of 99Tc-MDP,alendronate sodium in postmenopausal women with DTC under TSH suppression and osteoporosis.
The purpose of the study is to find out if the small dose of radioiodine, that is used for the dosimetry study on patients with differentiated thyroid cancer, may stun the cancer cells and make the thyroid cancer treatment less effective.
This research study is a phase I/II study of MLN0128 in metastatic anaplastic thyroid cancer(ATC) and incurably poorly differentiated or radioidodine refractory differentiated thyroid cancer (DTC). Due to changes in the manufacturing process which resulted in increased absorption of MLN0128 from capsules, a run-in phase I prior to the phase II of the study was needed. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied. The FDA (the U.S. Food and Drug Administration) has not approved MLN0128 as a treatment for any disease. MLN0128 prevents tumor cells from dividing and growing by selectively and potently inhibiting a chemical, mTOR kinase, which regulates cell growth and survival. Patients with anaplastic thyroid cancer have been observed to sometimes carry genetic alterations in their tumor cells which may make the cancer more sensitive to inhibition by MLN0128. Given the activity with everolimus in RAI refractory thyroid cancer, subjects wth metastatic, incurable differentiated RAI refractory and poorly differentiated thyroid cancer were included.
Primary Objective: To determine the efficacy (as assessed by progression-free survival [PFS]) of vandetanib when compared to placebo in participants with differentiated thyroid cancer that is either locally advanced or metastatic who are refractory or unsuitable for radioiodine therapy. Secondary Objectives: - To determine the efficacy of vandetanib when compared to placebo in this participant population as assessed by efficacy variables including duration of response (DOR), objective response rate (ORR), change in tumour size (TS) and overall survival (OS). - To evaluate the pharmacokinetics (PK) of vandetanib in this participant population and potentially investigate any influence of participant demography and pathophysiology on vandetanib PK. - To demonstrate an improvement in time to worsening of pain (TWP) in participants treated with vandetanib when compared to placebo in this participant population. - To evaluate the safety and tolerability of vandetanib treatment in this participant population.
