Filter by: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.
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.
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.
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.
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.
