Filter by:This phase II trial is studying how well AZD6244 works in treating patients with papillary thyroid cancer that did not respond to radioactive iodine. AZD6244 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
We will study the effect of taking eltroxin at different time, i.e. fasting or postprandial periods. We will also study the effect of levothyroxin treatment in Chinese people
The main purpose of this study is to see how well FDG-PET scans can determine the malignancy of thyroid nodules that have already been tested (and come back positive) by fine needle aspiration.
This was a parallel group, randomized, double blind, placebo controlled, multicentre study designed to assess whether vandetanib (ZD6474) conferred an improvement in PFS as compared to placebo in participants with locally advanced or metastatic papillary or follicular thyroid carcinoma failing or unsuitable for radioiodine therapy. The trial was of a sufficient size so that if vandetanib (ZD6474) was truly active there was a high probability that it would demonstrate an effect sufficiently promising to warrant a follow-up assessment. - Participants were seen weekly for the first 2 weeks, then again at Week 4, Week 8, and Week 12 after randomization, and every 12 weeks thereafter. Upon disease progression, all participants (both active and placebo) were unblinded and given the option to discontinue blinded study treatment and enter follow up and survival, or begin open label vandetanib (ZD6474) 300 mg treatment. All participants were followed to collect survival data until greater than or equal to (>=) 50% of participants had died. Participants who were taking vandetanib (ZD6474) at the time of study closure and wished to remain on therapy were allowed to continue for as long as the Investigator felt that they were obtaining clinical benefit, or until they were given another anti-cancer therapy. The safety data from all participants was assessed on an ongoing basis, including discontinuation and follow up. - Radiologic evaluation using RECIST criteria was performed every 12 weeks (+/- 2 weeks). All medical images were centralized assessed at the site and centrally reviewed. Participants were evaluated until progression, and then followed up for survival, regardless of whether they continued randomized treatment, unless they withdrew consent. Post progression open-label vandetanib (ZD6474) were offered at the investigators discretion. - All participants submitted a suitable archived tumor sample prior to randomization. In the event that a suitable archived sample was not available within 2 weeks prior to randomization, a fresh tumor sample was obtained in its place prior to randomization. If a participant underwent the fresh tumor biopsy procedure, this specimen would satisfy the first optional tumor biopsy submission should they consented to the exploratory part of the study.
This phase II trial studies how well giving sunitinib malate works in treating patients with iodine-refractory recurrent or metastatic thyroid cancer. Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor
Background: - Medullary thyroid carcinoma (MTC) is common in people with a genetic disorder called multiple endocrine neoplasia (MEN). - Vandetanib is an experimental drug that blocks a defective protein receptor (rearranged during transfection (RET) receptor) found on the surface of cancer cells in people with MEN. It is thought that this protein is a primary cause of MTC in people with MEN. Objectives: - To study the activity of Vandetanib in children and adolescents with MEN-related MTC by measuring the change in tumor size, in blood levels of proteins produced the tumor (calcitonin and carcinoembryonic antigen (CEA) and in tumor-related diarrhea. - To determine the safety and tolerability of Vandetanib in children and adolescents. - To study how the body handles Vandetanib in children and adolescents. - To determine the effect of Vandetanib on the survival of children and adolescents with MTC. Eligibility: -Children and adolescents 5 to 18 years of age with MTC whose tumor cannot be surgically removed or has grown back after treatment or has metastasized (spread beyond the thyroid gland). Design: - Patients take Vandetanib once a day in 28-day cycles. The first patients enrolled in the study are started on a low dose of Vandetanib to determine tolerability. - Patients have periodic blood tests, electrocardiograms, and blood pressure measurements to look for side effects of Vandetanib. - Blood tests and imaging scans (magnetic resonance imaging (MRI), computed tomography (CT), bone and octreoscan) are done every 8 weeks for the first 32 weeks of treatment and then every 16 weeks for the duration of the treatment period. - Patients who have tumor-related diarrhea keep a daily record of the number and consistency of bowel movements.
Due to arguments showing that angiogenesis could be involved in progression of metastatic thyroid carcinoma and to objective response during previous studies with sunitinib (an angiogenic oncology drug also known as Sutent), this study, THYSU, is justified to evaluate the efficacy of sunitinib in metastatic thyroid carcinoma. Furthermore, the standard treatment of metastatic thyroid carcinoma when a general treatment is to be prescribed is limited to radioiodine. When radioiodine becomes ineffective, there is no standard treatment despite some use of chemotherapy. The objective of the trial is to determine the objective tumor response rate (efficacy) in patients with locally advanced or metastatic anaplastic, differentiated or medullary thyroid carcinoma treated with sunitinib; a secondary objective is to evaluate the safety of sunitinib in these patients. The THYSU trial is a phase II, French multi-center study. This trial's plan is to enroll 75 patients with locally advanced or metastatic anaplastic, differentiated or medullar thyroid carcinoma.
The purpose of this study is to determine the relationship of hemodynamic parameters with the level of thyroid hormones and the histological structure of thyroid nodules in euthyroid patients.
The purpose of the study is to determine the safety and efficacy of combretastatin combined with paclitaxel and carboplatin in the treatment of anaplastic thyroid cancer (ATC).
Residents of certain villages in Kazakhstan were exposed during childhood to radioactive fallout from nuclear tests conducted at the Semipalatinsk Nuclear Test Site (SNTS) between 1949 and 1962. Radiation doses to the thyroid from external and internal (i.e., ingested) radiation sources deposited as fallout are of interest because they may be jointly and differentially associated with increased risk of thyroid disease in this population. Objectives: To collect information about factors influencing radiation dose to the thyroid gland in children of two ethnic groups who were exposed to radioactive fallout from nuclear tests at the SNTS between 1949 and 1962. The two groups are Kazakhs (historically nomadic herders) and Europeans (typically descendants of Russian and German farmers). Eligibility: Women 70 years of age and older who had children or provided care to children during the 1950s. Men age 70 and older who were engaged in farming and care of dairy animals at the time of the nuclear tests. Design: In focus group format, participants are interviewed to collect information on the following at the time of nuclear tests: - Dairy consumption; - Source, storage and availability of milk and milk products; - Time that children of different ages and ethnic groups spent indoors; - Building material of houses and schools; - Herding, grazing and supplemental feed of dairy animals.
