Active clinical trials for "Thyroid Neoplasms"

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.

Patients diagnosed with thyroid cancer are commonly treated with surgery to remove their thyroid gland followed by radioiodine ablation to destroy any remaining parts of the thyroid gland that may have been missed during surgery. It is thought that ablation with radioiodine destroys normal remaining thyroid tissue as well as cancerous cells either in the thyroid area or at other sites. Following successful treatment, patients are then monitored by their physicians at regular intervals with testing to detect any recurrence of thyroid cancer throughout the body. If thyroid cells are detected by these follow up tests, the physician will decide the best method to re-treat the patient. In 2001-2003 Genzyme conducted a clinical study to test if Thyrogen® can be used to accomplish radioiodine ablation treatment. This study aimed to determine that the success rates of radioiodine ablation were comparable when patients were prepared for ablation with Thyrogen® while being maintained on their normal thyroid hormone therapy, or, alternatively, by thyroid hormone withdrawal. Thyroid hormone withdrawal commonly causes uncomfortable side effects for patients, and these might be avoided by the use of Thyrogen. Eight months after the initial Thyrogen plus radioiodine treatment to achieve ablation, all patients in both groups were given Thyrogen® to test for any remaining thyroid tissue. The results of this testing showed that all patients (in both groups) had successfully achieved remnant ablation and had no detectable thyroid tissue remaining. In order to confirm these remnant ablation results we will conduct follow up testing in this study for all patients that were enrolled in the previous study and we also will determine if their thyroid cancer has recurred. Only patients who completed this previous Thyrogen ablation study are eligible for entry into this study.

The goal of this research is to compare the effects on psychological distress between T4 mono replacement group and T4/T3 combination replacement group after total thyroidectomy in thyroid cancer patients. Subjects: Psychologically distressed patients, such as depression, anxiety, and fatigue patient after total thyroidectomy with thyroid cancer are considered for participation. Screening of distress after total thyroidectomy is used HADS (Hospital Anxiety and Depression Scale) ≥ 8 for depression or anxiety, and MDASI-F (MD Anderson Symptom Inventory -Fatigue) ≥ 4 for fatigue. Randomization: Using the table of random sampling numbers, patients assign to T4 mono replacement group or T4/T3 combination replacement group. Evaluation for distress: Assessment will be made baseline, 4 weeks, 12 weeks and 24 weeks to investigate change of psychological distress (depression, anxiety, and fatigue). Level of distress after thyroidectomy will determine using Hospital Anxiety and Depression Scale (HADS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) for depression or anxiety, and Brief Fatigue Inventory (BFI) for fatigue.

The purpose of this study is to test the safety of durvalumab (MEDI4736) and tremelimumab in combination with radiation therapy and find out what effects, if any, this combination has on people, and whether it improves overall survival.

Trial of sorafenib versus placebo in the treatment of locally advanced or metastatic differentiated thyroid cancer refractory to radioiodine

Background: Patients who have advanced thyroid cancer have a low long-term survival rate. These types of thyroid cancer do not respond well to conventional surgery or radiation, or to specific thyroid cancer treatments such as radioactive iodine treatment and thyroid hormone for thyroid stimulating hormone (TSH) suppression. Valproic acid has long been approved as an anticonvulsant to treat seizures in patients with epilepsy. It has also been used to treat bipolar disorder. Recent studies have shown that valproic acid has promising effects in thyroid cancer treatment because it may help destroy cancer cells and help conventional treatments be more effective. However, valproic acid is not approved for thyroid cancer and is therefore an investigational drug. Objectives: To determine whether valproic acid can inhibit tumor growth or induce tumor cell death. To determine whether valproic acid can make tumor cells increase their uptake of radioiodine. Eligibility: - Individuals at least 18 years of age who have advanced-stage thyroid cancer that is either unresponsive to conventional treatments or fails to absorb radioiodine. Design: Eligible participants will continue on the standard thyroid hormone suppression therapy and begin receiving valproic acid for a total of 10 weeks. Participants will keep a study diary to record doses and side effects, and will have regular clinic visits to provide blood samples and receive additional valproic acid. After 10 weeks, participants will have a Thyrogen scan to measure radioiodine uptake after valproic acid therapy. Tumor biopsies and blood samples will be taken at this time. If there is increased radioiodine uptake on the scan, participants will have additional radioiodine therapy. If there is no increased uptake on the scan, participants will continue on valproic acid for 7 more weeks. After 16 total weeks of treatment, additional blood samples and scans will be taken. Participants may continue to take valproic acid if the thyroid cancer appears to be responding to the treatment. Follow-up visits will be scheduled at 3, 6, 9 (for patients continuing on valproic acid only), and 12 months.

The purpose of this study is to examine the safety and evaluate the response of VB-111 on DTC.

This phase I trial is studying the side effects and best dose of iodine I 131 when given together with pazopanib hydrochloride in treating patients with recurrent and/or metastatic thyroid cancer previously treated with iodine I 131 that cannot be removed by surgery. Radioactive drugs, such as iodine I 131, may carry radiation directly to cancer cells and not harm normal cells. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving iodine I 131 together with pazopanib hydrochloride may be an effective treatment for thyroid cancer.

The primary objective of this clinical study is to determine whether the inhibition of cytochrome P450 (CYP) isozyme CYP2C8 by XL184 observed in in vitro preclinical studies translates into the potential for clinically significant drug-drug interactions in humans. The study will measure the effect of once daily dosing of XL184 on the pharmacokinetics (PK) of rosiglitazone. The PK of XL184 when combined with rosiglitazone will be evaluated as well. A specific objective of this study is to determine whether the interaction between XL184 and a drug such as rosiglitazone is sufficiently large enough to necessitate a dosage adjustment when used in combination with XL184, or whether the interaction would require additional therapeutic monitoring. Rosiglitazone, commonly known as Avandia, is a prescription medicine approved by the FDA used to treat adults with Type 2 (adult-onset or non-insulin dependent) diabetes mellitus (high blood sugar). In this study, subjects will only take 2 doses of rosiglitazone. There is no intention of therapy as a result of taking rosiglitazone in this study.

This study is comparing a drug called Sutent with standard of care treatment for people with advanced thyroid cancer. Because advanced thyroid cancer is becoming increasingly common and effective treatment options are limited, new therapies are desperately needed. This study is designed to see if Sutent following therapy with radioactive iodine will target cancer cells and delay disease progression better than standard therapy alone. Newly diagnosed patients, who are scheduled to receive radioactive iodine as part of their standard care are possible candidates. By entering into this study, participants agree to take oral Sutent for approximately two years after completing standard therapy. During this time, study participants will be followed closely by their doctor.
