NCT ID: NCT00176748 Completed - Thyroid Cancer Clinical Trials

Treatment for Patients With Metastatic Thyroid Cancer

Start date: July 2005
Phase: Phase 2
Study type: Interventional

This study is being done to find out the good and bad effects of an investigational drug that is not approved for sale, called AG-013736. Tumors need blood vessels in order to continue to grow, and AG-013736 is thought to work by playing a role in preventing new blood vessels from growing. We want to see if AG-013736 has any effect on your disease by making your tumor smaller and if so, for how long. We also want to test the safety [the effect on your body] of AG-013736 and to measure the amount of AG-013736 that gets into your blood. AG-013736 has been given to over 140 patients with cancer on other studies.

NCT ID: NCT00150033 Completed - Thyroid Diseases Clinical Trials

Health-Related Quality of Life for Thyroid Patients

Start date: May 2005
Phase: Phase 2
Study type: Observational

Background: Thyroid diseases are frequent. They include both metabolic changes and gland enlargement (goitre). Previous research and clinical suspicion indicate that the life quality of many patients is reduced despite successful treatment. Research methods are, however, weak, and a well-tested, disease specific quality of life questionnaire is especially needed. Several treatment possibilities exist for each thyroid disease. For example, hypermetabolism can be treated with either medication, radioactive iodine or by surgery. No comparative studies of quality of life using the different treatment modalities exist. Purpose: To develop and evaluate a questionnaire to measure health-related quality of life in patients suffering from thyroid diseases. Methods: To ensure that all relevant aspects are included, the questionnaire will be developed on the basis of a systematic examination of the scientific literature and interviews with 13 physicians and 100 patients. The questionnaire will then be tested by 100 new patients. After revision, the questionnaire will be answered by 1000 patients with a view to scientifically investigate the measuring capacity of the questionnaire. This will be done using traditional psychology methods (psychometry) as well as modern statistical methods (structural equations for categorical data and "item response" models). Relevance: The above-mentioned questionnaire is necessary for clarifying whether these diseases reduce quality of life and, in the long-term, whether a difference in quality of life exists using the different treatment alternatives and whether treatment can be improved. It should also be included in quality protection studies, in the evaluation of new treatment modalities and possibly also in the treatment of the individual patient.

NCT ID: NCT00148213 Completed - Thyroid Neoplasms Clinical Trials

Clinical Evaluation of a New Highly Sensitive Thyroglobulin Assay in Differentiated Thyroid Carcinoma

Start date: September 2003
Phase: N/A
Study type: Observational

Human thyroglobulin (Tg) is the most sensitive biochemical marker for recurrence of differentiated cancer (DTC), especially after the complete removal of thyroid tissue through surgery and radioiodine therapy (RIT). Unfortunately, current assays for measuring Tg in blood samples are not sensitive enough to reliably measure Tg while patients are under thyroid hormone replacement therapy. Instead patients have to withdraw thyroid hormone for several weeks or receive costly injections of recombinant thyroid stimulating hormone (TSH) in order to raise Tg production by thyroid remnant and/or thyroid cancer cells so that it can be measured by current Tg assays. Other patients have antibodies against Tg that interfere in current immunoassays. The purpose of the study was to characterize a new highly sensitive assay for measuring Tg in the serum in thyroid cancer patients both on thyroid hormone therapy and off therapy in comparison to the normal routine assay already in use at Münster University Hospital.

NCT ID: NCT00144079 Completed - Thyroid Neoplasms Clinical Trials

Multicenter Study Differentiated Thyroid Carcinoma

Start date: January 2000
Phase: Phase 3
Study type: Interventional

The trial examines the clinical benefit of adjuvant external beam radiotherapy (RTx) for locally invasive differentiated carcinoma (TNM stages pT4 pN0/1/x M0/x; 5th ed. 1997) of the thyroid gland (DTC). Patients are treated with surgery (thyroidectomy and lymphadenectomy), radioiodine therapy (RIT) to ablate the thyroid remnant tissue, and TSH-suppressive L-thyroxine therapy with or without RTx after documented elimination of cervical I-131 uptake.

NCT ID: NCT00134043 Completed - Clinical trials for Recurrent Thyroid Cancer

Suberoylanilide Hydroxamic Acid in Treating Patients With Metastatic and/or Locally Advanced or Locally Recurrent Thyroid Cancer

Start date: December 2005
Phase: Phase 2
Study type: Interventional

This phase II trial is studying how well suberoylanilide hydroxamic acid works in treating patients with metastatic and/or locally advanced or locally recurrent thyroid cancer. Drugs used in chemotherapy, such as suberoylanilide hydroxamic acid, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Suberoylanilide hydroxamic acid may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

NCT ID: NCT00124527 Completed - Thyroid Cancer Clinical Trials

Study of Irofulven Plus Capecitabine in Patients With Advanced Thyroid Cancer

Start date: March 31, 2005
Phase: Phase 2
Study type: Interventional

Irofulven is an investigational chemotherapeutic agent being studied in a variety of solid tumors. The purpose of this study is to assess the efficacy and safety of irofulven/capecitabine combination therapy in patients with anaplastic, medullary, or locally advanced/metastatic differentiated thyroid cancer.

NCT ID: NCT00121628 Completed - Thyroid Cancer Clinical Trials

A Phase 2, Open-label Study of AMG 706 to Treat Subjects With Locally Advanced or Metastatic Thyroid Cancer

Start date: July 2005
Phase: Phase 2
Study type: Interventional

The purpose of the study is to determine if AMG 706 will have clinically meaningful anti-tumor activity in subjects with locally advanced or metastatic thyroid cancer who are not candidates for radioactive iodine therapy or local therapies.

NCT ID: NCT00118248 Completed - Clinical trials for Recurrent Thyroid Cancer

Tanespimycin in Treating Patients With Inoperable Locoregionally Advanced or Metastatic Thyroid Cancer

Start date: December 2004
Phase: Phase 2
Study type: Interventional

This phase II trial is studying how well tanespimycin works in treating patients with inoperable locoregionally advanced or metastatic thyroid cancer. Drugs used in chemotherapy, such as tanespimycin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

NCT ID: NCT00106119 Completed - Thyroid Diseases Clinical Trials

Thyroid and Glucose and Energy Metabolism

Start date: March 2005
Phase: Phase 2
Study type: Interventional

This study will examine how two thyroid preparations-levothyroxine (T4) and liothyronine (T3)-affect fat and cholesterol metabolism, blood sugar regulation, and thyrotropin secretion in patients who have had their thyroid gland removed. Results of the study may help in the development of better therapies to optimize blood sugar and cholesterol levels in some patients. Patients 18 years of age or older who have had most or all of their thyroid gland removed and are taking long-term thyroid hormone medication may be eligible for this study after screening.

NCT ID: NCT00104871 Completed - Clinical trials for Recurrent Thyroid Cancer

Bortezomib in Treating Patients With Metastatic Thyroid Cancer That Did Not Respond to Radioactive Iodine Therapy

Start date: December 2004
Phase: Phase 2
Study type: Interventional

This phase II trial is studying how well bortezomib works in treating patients with metastatic thyroid cancer that did not respond to radioactive iodine therapy. Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth
