Active clinical trials for "Thyroid Neoplasms"

This phase II trial is studying how well aflibercept works in treating patients with recurrent and/or metastatic thyroid cancer that has not responded to radioactive iodine therapy. Aflibercept may stop the growth of tumor cells by blocking blood flow to the tumor and by carrying tumor-killing substances directly to thyroid cancer cells.

The purpose of this study is to determine the safety and efficacy of oral lenvatinib in participants with medullary thyroid cancer (MTC) or radioiodine (131 I)-refractory/resistant differentiated thyroid cancer (DTC), unresectable differentiated thyroid cancers, stratified by Histology.

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.

This phase II clinical trial studies how well thermal ablation and spine stereotactic radiosurgery work in treating patients with cancer that has spread to the spine (spine metastases) and is at risk for compressing the spinal cord. Thermal ablation uses a laser to heat tumor tissue and helps to shrink the tumor by destroying tumor cells. Stereotactic radiosurgery delivers a large dose of radiation in a short time precisely to the tumor, sparing healthy surrounding tissue. Combining thermal ablation with stereotactic radiosurgery may be a better way to control cancer that has spread to the spine and is at risk for compressing the spinal cord.

Primary Objective: To determine the efficacy (as assessed by progression-free survival [PFS]) of vandetanib when compared to placebo in participants with differentiated thyroid cancer that is either locally advanced or metastatic who are refractory or unsuitable for radioiodine therapy. Secondary Objectives: To determine the efficacy of vandetanib when compared to placebo in this participant population as assessed by efficacy variables including duration of response (DOR), objective response rate (ORR), change in tumour size (TS) and overall survival (OS). To evaluate the pharmacokinetics (PK) of vandetanib in this participant population and potentially investigate any influence of participant demography and pathophysiology on vandetanib PK. To demonstrate an improvement in time to worsening of pain (TWP) in participants treated with vandetanib when compared to placebo in this participant population. To evaluate the safety and tolerability of vandetanib treatment in this participant population.

The purpose of this Phase 2 study is to find out what effect, good and/or bad, external beam radiation therapy, has on the patient and their thyroid cancer where surgery is not an option or where despite surgery, the disease is still present.

This phase II trial studies how well cabozantinib-s-malate works in treating patients with thyroid cancer that does not respond to treatment. Cabozantinib-s-malate may stop the growth of thyroid cancer by blocking some of the enzymes needed for cell growth. Cabozantinib-s-malate may also stop the growth of thyroid cancer by blocking blood flow to the tumor.

This is a Phase 1, open-label, multicenter, randomized, 2-stage crossover study consisting of 2 phases: Stage I - Pharmacokinetics (Bioequivalence), with an Extension Stage II - Pharmacokinetics (Food Effect) with an Extension This study will enroll approximately 60 subjects in stage I and 60 subjects in stage II with hematologic or solid tumor malignancies, excluding gastrointestinal tumors and tumors that have originated or metastasized to the liver for which no standard treatment exists or have progressed or recurred following prior therapy. Subjects must not be eligible for therapy of higher curative potential where an alternative treatment has been shown to prolong survival in an analogous population. Approximately 23 sites in the US and 2 in Canada will participate in this study.

This study is being done to see if the radioisotope 99mTc sestamibi scans can locate what is causing the elevated serum thyroglobulin in persons with differentiated thyroid cancer who have elevated serum thyroglobulin levels and negative diagnostic imaging tests. This is for patients with: Elevated suppressed or stimulated thyroglobulin level (Tg) > 10 ng/ml with or WITHOUT thyroglobulin antibodies , All NEGATIVE standard diagnostic clinical imaging studies (NSDCIS) = negative ultrasound (US), diagnostic radioiodine scan (DRS), chest-x-ray (CXR), computer tomography with or without contrast (CT), and 18F-Fluoro-deoxyglucose positron emission computer tomography scan (18F-FDG PET) within the last 12 mos. If EDCIS (extensive diagnostic clinical imaging studies of 18F-sodium fluoride positron emission computer tomography scan (18F NaF PET) or 99mTc methylene diphosphonate bone scan (99mTc MDP), AND negative brain CT or magnetic resonance (MR) are performed, these are also negative. Voluntary patients will have sestamibi scan performed in 4 phases: Phase 1: receive an injection into their vein of a radioisotope called 99mTc sestamibi. Phase 2: wait for 60 to 90 minutes in a waiting room Phase 3: imaged lying face up on an imaging table while a camera passes around you from the top of the head to approximately the level of knees. This requires approximately 45 minutes Phase 4: images will be reviewed by the nuclear medicine physician. This will take ~10-15 minutes. If additional images are required to clarify an image, then additional images of that area will be performed on the same camera or an alternate camera. As earlier, the additional images performed lying face up. These images require ~20-45 minutes. The patient will then be released. The risk of this study is considered very low, and the potential benefits to the patient are considered very high.

This will be a Phase II, open label study to establish the effect of once-daily oral doses of ZD6474 100mg in subjects with locally advanced or metastatic hereditary medullary thyroid cancer in whom no standard therapeutic option is available.
