Filter by:This phase II trial is studying how well romidepsin works in treating patients with recurrent and/or metastatic thyroid cancer that has not responded to radioactive iodine. Romidepsin may stop the growth of tumor cells by blocking the some of the enzymes needed for cell growth. It may also help radioactive iodine and chemotherapy work better by making tumor cells more sensitive to the drug
The purpose of this open label, two stage, phase II study is to evaluate the efficacy and tolerability of ZD6474 in patients with locally advanced or metastatic hereditary medullary thyroid carcinoma.
RATIONALE: Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. PURPOSE: Phase II trial to study the effectiveness of gefitinib in treating patients who have locally advanced or metastatic thyroid cancer that did not respond to iodine therapy.
This is a Phase 2 study being conducted at multiple centers in the United States. Patients having thyroid cancer that has spread to other parts of the body (i.e., metastatic) are eligible to participate. Patients must have disease that was not controlled by previous treatment with radioactive iodine (131I) or not be good candidates for such treatment. The purpose of the study is to test whether the angiogenesis inhibitor AG-013736 is an effective treatment for metastatic thyroid cancer as shown by the number of patients in the study who experience significant and durable tumor shrinkage.
This phase II trial is studying how well decitabine works in treating patients with metastatic papillary thyroid cancer or follicular thyroid cancer that has stopped responding to radioactive iodine. Iodine I 131 (radioactive iodine) kills thyroid cancer cells. Metastatic thyroid cancer cells can lose the ability to be treated with radioactive iodine. Decitabine may help thyroid cancer cells regain the ability to respond to treatment with radioactive iodine.
This study will examine whether and how levothyroxine (Synthroid, a synthetic thyroid hormone) affects the way the body handles other drugs. If levothyroxine does affect the metabolism of other drugs, the dose of those medications may need to be increased to enhance their action or decreased to avoid adverse reactions. Patients 18 years of age and older with thyroid cancer who are participating in NIH protocol #77-DK-0096 and are receiving long-term suppression therapy with levothyroxine may be eligible for this study. This is not a study of thyroid cancer or of potential new drugs to treat it. Thyroid cancer patients are being studied because their treatment regimen provides an opportunity to study drug metabolism while patients are both on and off levothyroxine therapy. Participants come to the NIH Clinical Center on two occasions: once while they are regularly taking their levothyroxine, and once while they are off the medication in preparation for their radioactive iodide diagnostic scan for the procedures outlined below. The time interval between the two clinic visits depends on whether the first visit is while the patient is on or off medication. Participants are asked to fast overnight before each visit and to abstain from certain foods and beverages for 48 to 72 hours before the visit. At each visit, patients undergo the following procedures: - Medication history, limited physical examination, and blood draw for laboratory tests, including a test to look for genes important in eliminating medications from the body. - Insertion of a catheter (thin plastic tube) into an arm vein for collecting blood samples. - Shave skin biopsy (optional) to explore how proteins in the skin that metabolize and transport drugs are affected by thyroid hormone. For this procedure, the skin is cleaned, numbed with medicine, and a small sample of the top layer is removed with a razor blade. The wound heals in 2 to 3 days. - Medication dosing. Participants take all of the following substances by mouth at the same time: 1) 200 mg of caffeine, a compound commonly found in chocolate, soda/pop, coffee, tea and non-prescription products to prevent sleep; 2) 30 mg of dextromethorphan, a non-prescription cough suppressant; 3) 40 mg of omeprazole, a prescription drug for heartburn and stomach ulcers; 4) 8 mg of midazolam, a prescription drug used to cause relaxation and drowsiness; and 5) 120 mg of fexofenadine, a non-sedating prescription antihistamine used to treat allergies. - Blood and urine sampling. Fifteen blood samples of about 5 mL (1 teaspoon) each are collected through the catheter and urine is collected over the next 24 hours to determine what happens to the test drugs in the body. Participants may resume their normal diet 4 hours after taking the study medications.
This phase I trial is studying the side effects of gefitinib in treating patients with metastatic or unresectable head and neck cancer or non-small cell lung cancer. Gefitinib may stop the growth of cancer cells by blocking the enzymes necessary for their growth
This study will determine the safety and activity of a new formulation of thyrotropin-releasing hormone (TRH), a drug used for diagnosing and evaluating patients with certain thyroid gland abnormalities. Normal thyroid gland function depends on proper chemical signaling between the thyroid gland, the hypothalamus (the part of the brain where TRH is made), and the pituitary (another part of the brain). The TRH test helps assess this interaction. Production of the only FDA-approved preparation of TRH was stopped in July 2002. As a result, to have a continuous source of TRH available for NIH clinical and research purposes, the NIH Clinical Center (CC) Pharmacy Department produced a pharmaceutical grade formulation of TRH for patient use. This study will test the CC formulation in healthy volunteers to show that its activity and side effects are similar to those of the previously available commercial test preparation. It will then be studied in CC patients for whom the diagnostic test is recommended. Healthy volunteers between 18 and 65 years of age and all patients requiring TRH evaluation of hypothalamic-pituitary-thyroid gland interaction may be eligible for this study. Patients include those with pituitary reserve, inconsistent thyroid function test, inappropriate TSH secretion, or pre- and post-operative evaluation of pituitary tumors. Normal volunteers will be screened with a medical history, physical examination, and blood tests. Women of child-bearing potential will be given a pregnancy test; pregnant and breast-feeding women may not participate. The TRH test procedure will be the same for healthy volunteers and patients. All participants fast from midnight before the morning of the test. In the morning, a catheter (flexible plastic tube) is inserted into an arm vein for easy injection of the TRH and collection of blood samples. Blood pressure is monitored before and during the test. A blood sample is drawn, and then TRH is given through the catheter over a 1-minute period. Another nine blood samples are collected over a 3-hour period from the time of the TRH injection for measuring levels of various hormones. A total of less than 4 tablespoons of blood is taken for the test.
This study will determine the pathways between Mohawk cultural identification and specific behaviors related to pollutant exposure, and determine the effects of these factors and the pollutant exposure on physiologically and socially significant outcomes.
RATIONALE: Thalidomide may stop the growth of thyroid cancer by stopping blood flow to the tumor. PURPOSE: Phase II trial to study the effectiveness thalidomide in treating patients who have thyroid cancer.
