Filter by:Postmenopausal women with differentiated thyroid cancer (DTC) taking suppressive doses of levothyroxine (L-T4) are thought to have accelerated bone loss and increased risk of osteoporosis. Therefore, the investigators try to investigate the effects of 99Tc-MDP,alendronate sodium in postmenopausal women with DTC under TSH suppression and osteoporosis.
The purpose of the study is to find out if the small dose of radioiodine, that is used for the dosimetry study on patients with differentiated thyroid cancer, may stun the cancer cells and make the thyroid cancer treatment less effective.
This research study is a phase I/II study of MLN0128 in metastatic anaplastic thyroid cancer(ATC) and incurably poorly differentiated or radioidodine refractory differentiated thyroid cancer (DTC). Due to changes in the manufacturing process which resulted in increased absorption of MLN0128 from capsules, a run-in phase I prior to the phase II of the study was needed. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied. The FDA (the U.S. Food and Drug Administration) has not approved MLN0128 as a treatment for any disease. MLN0128 prevents tumor cells from dividing and growing by selectively and potently inhibiting a chemical, mTOR kinase, which regulates cell growth and survival. Patients with anaplastic thyroid cancer have been observed to sometimes carry genetic alterations in their tumor cells which may make the cancer more sensitive to inhibition by MLN0128. Given the activity with everolimus in RAI refractory thyroid cancer, subjects wth metastatic, incurable differentiated RAI refractory and poorly differentiated thyroid cancer were included.
This Expanded Access Program (EAP) consists of a Prerandomization Phase and a Randomization Phase. Only subjects with radioiodine-refractory DTC who fulfill the eligibility criteria will be treated. These subjects will be treated until progression of disease or unacceptable toxicity.
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 study is designed to evaluate the clinical efficacy, safety and tolerability of selumetinib with radioactive iodine therapy in patients with differentiated thyroid cancer.
- Background: BRAFV600E is the most frequent oncogene in differentiated thyroid cancer (DTC) occurring in about 50% of cases. Clinical trials with tyrosine kinase inhibitors (TKI) with specific activity against BRAF in metastatic radioiodine-resistant DTC (MRR-DTC) are ongoing. Very recently it has been demonstrated that DTC often consists of a mixture of tumor cells with wild-type and mutant BRAF. The subclonal occurrence of BRAFV600E in MRR-DTC could disable the therapy with BRAF targeted TKI and be responsible of the frequent defeats of this treatment. A therapeutic strategy based upon BRAF inhibitors in tumors bearing subclonal BRAFV600E could be initially successful hitting the tumor cells expressing the oncogene, and after the initial tumor growth arrest and/or shrinkage, the oncogene negative cells insensitive or less sensitive to the treatment, could restart the growth of the tumor causing the progression of the disease and the escape from the clinical response. - Aims: To determine the impact of subclonal BRAFV600E on the efficacy of BRAF inhibitors in the treatment of MRR-DTC. - Study design: Primary tumor tissues will be analyzed for the presence of BRAFV600E by pyrosequencing or other quantitative assay. If available, synchronous metastases and post-therapy metachronous metastases will be analyzed as well. The clinical response will be determined according to RECIST, and the association with the percentage of BRAFV600E alleles will be evaluated. Attention will be paid to the possible difference of BRAFwild-type/BRAFV600E ratio between primary tumors and synchronous metastases, primary tumors and post-therapy metachronous metastases, and between responsive and resistant synchronous tumor lesions.
After initial treatment of differentiated thyroid cancer patients (DTC) are followed by a blood test, a biomarker called thyroglobulin, in order to detect a possible recurrence. Nowadays patients are treated 'blindly' with high dose radioactive iodine to treat a suspected recurrence. However, the scan made after therapy to verify the effect of the treatment shows that in up to 50% the treatment could be considered as futile. 124I - a radioactive isotope - in combination with whole body PET became recently available for use in the follow-up of DTC. This could make it possible before the therapy with high dose radioactive iodine to determine the extensiveness of the disease and whether effect of the therapy could be expected. Additionally, recurrent DTC lesions that do not accumulate iodine can be found without the futile treatment with 131I. FDG-PET (another PET modality) is able to detect these lesions. The value of FDG-PET before 131I treatment however has not been tested. The combination of these two diagnostic tools, 124I-PET and FDG-PET, has a potential to allow earlier and better restaging and selection for treatment
Thyroid cancer is a relatively rare disease but its incidence is increasing in many countries.. Early and accurate diagnosis leading to earlier treatment and intervention is recognised as a major factor in determining a good outcomes. This study will investigate new ways of diagnosing thyroid cancer from blood samples using proteomic and genetic markers. The study will take samples from patients with differentiated thyroid cancer and measure relative quantities of 1000s of proteins within the blood. These measures will be explored to see if, when used in combination they can accurately diagnose thyroid cancer. If successful this technique could be extended to routine screening and could replace more invasive tests currently used. Participants will be required to supply a small sample of blood, answer questions on their medical history and also consent for their medical records to be examined. A lifestyle questionnaire will also be supplied to each participant. In the case where a diagnosis is predicted for a condition the participant was not aware of the medical team will discuss the best interests of the patient with their GP and if required refer them to a suitable specialist. The study will run for 24 months and will routinely process around 15 and 20 participants with a history of thyroid cancer per month. All patient details will be kept confidential and only non identifiable information will leave the clinic. The work will be published and if successful will be validated on another site, commercialised and made available for routine clinical use.
The goal of this study is to determine the effect of combining everolimus and sorafenib in patients with metastatic differentiated thyroid cancer who progressed on sorafenib alone.
