Active clinical trials for "Thyroid Neoplasms"

The purpose of this study is to evaluate the tumor response rate in patients with metastatic medullary thyroid cancer (MTC) or radioiodine resistant differentiated thyroid cancer (DTC) after receiving treatment with LBH589 20 mg by mouth, three times weekly. Time to progression, overall survival, toxicity, tolerability, and Notch1 protein expression patterns will also be evaluated.

Since thyroid cancer becomes refractory to radioactive iodine, treatment options are very limited. Tyrosine kinase inhibitors such as sorafenib have recently shown promise. This trial seeks to expand treatment options for this disease with a new, oral drug called RAD001. It is an inhibitor of the mTOR pathway and has shown activity in neuroendocrine cancers of the gastrointestinal tract and has been approved for the treatment of metastatic renal cell cancer.

Phase II clinical trial assessing efficacy and toxicity of pretargeted radioimmunotherapy using anti-CEAxanti-DTPA bispecific antibody and di-DTPA-131I peptide in patients with reccurrence of medullary thyroid carcinoma (abnormal calcitonin level and biomarkers doubling time lower than 5 years)

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.

RATIONALE: Celecoxib may stop the growth of thyroid cancer by stopping blood flow to the tumor and by blocking the enzymes necessary for tumor cell growth. PURPOSE: Phase II trial to study the effectiveness of celecoxib in treating patients who have progressive metastatic differentiated thyroid cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy in treating patients who have previously untreated anaplastic thyroid cancer.

A mono centre study to evaluate the efficacy of SOM230 in patients with progressive metastatic or postoperative persistent medullary thyroid cancer.

Differentiated thyroid cancer includes papillary, follicular, Hurthle cell, and C-cell/medullary carcinoma. Even though incidence is relatively low (1% of all neoplasms), a rise in this disease has been recorded in the country (The Atlas of Cancer Mortality in Colombia, 2010). Although this disease has a low rate of attributable mortality, the costs arising from treatment, monitoring, and disabilities among affected patients and their families are high for the health system. The therapeutic approach to differentiated thyroid cancer once it starts progressing is limited; there are no truly favorable treatment options for patients with advanced thyroid cancer: available options include surgery, radiotherapy, and radioactive iodine therapy. Molecular biology now allows the identification of the effects of mutations and alterations in the proteins that participate in cell signaling which account for dedifferentiation, invasiveness, and the progression of neoplastic cells. VEGFR (vascular endothelial growth factor receptor) is one of the main molecules to be addressed by targeted molecular therapy. Its increased expression in differentiated thyroid cancer has been demonstrated and has been associated with increased growth, invasiveness, and shorter recurrence-free survival. Different agents are effective against this tyrosine kinase receptor; nevertheless, taking into account that it is not solely responsible for tumor progression, according to clinical study results, it is more reasonable to use non-selective tyrosine kinase inhibitors such as sorafenib and motesanib. These inhibitors have already been tested in phase II studies. Results from recent phase II research studies using these emerging treatment options have shown important effects in the therapeutic approach to other solid neoplasms. Information about the safety of this type of treatment is limited; a need for information regarding the use of new therapeutic approaches in Colombia is one of the contributions that the National Institute of Cancer can make to the country through this study.

The objectives of this study are to evaluate safety, efficacy and pharmacokinetics of sorafenib for the treatment of Japanese patients with anaplastic thyroid carcinoma (ATC) or locally advanced or metastatic medullary thyroid carcinoma (MTC).

Radioactive iodine therapy is often part of the standard treatment for Papillary Thyroid Carcinoma (PTC) patients. However, in many patients, tumors develop a resistance or no longer respond to radioactive iodine therapy (iodine-refractory). Several lines of evidence suggest that blocking the BRAF gene may help to re-sensitize the tumors to radioactive iodine. BRAF is a protein that plays a central role in the growth and survival of cancer cells in some types of PTC. The investigational drug GSK2118436 may work by blocking the BRAF protein in cancer cells lines and tumors that have a mutated BRAF gene. In this research study, the investigators are looking to see if GSK2118436 can re-sensitize iodine-refractory PTC to radioactive iodine therapy. The investigators are also looking at the safety of adding GSK2118436 to radioactive iodine therapy.
