Active clinical trials for "Thyroid Neoplasms"

This phase II trial studies how well intensive blood pressure management works in decreasing systolic blood pressure in patients with kidney or thyroid cancer that has spread to other places in the body (metastatic) who are starting anti-angiogenic tyrosine kinase inhibitor cancer therapy. This study is being done to find out if a systolic blood pressure to a target of less than 120 mmHg (intensive systolic blood pressure management) can be achieved, well tolerated, and beneficial as compared to the usual approach to a target of less than 140 mmHg while taking an anti-angiogenic tyrosine kinase inhibitor. This study may help doctors understand the best way to control blood pressure in kidney or thyroid cancer patients taking anti-angiogenic tyrosine kinase inhibitor.

This is a single-centre open label phase II study evaluating the effect of lenvatinib treatment for restoring radioiodine uptake and retention in radioiodine-refractory (RAI-R) thyroid cancer to warrant I-131 therapy.

This study was conducted in patients with differentiated thyroid cancer who had undergone total/near-total thyroidectomy. After surgery patients were randomized to one of two methods of performing thyroid remnant ablation. One group of patients who took thyroid hormone medicine and were euthyroid [i.e. their thyroid stimulating hormone (TSH) levels are normal], and received injections of rhTSH (0.9 mg daily on two consecutive days) followed by oral radioiodine. The second group of patients did not take thyroid hormone medicine so that they were hypothyroid (i.e. their TSH levels were high), and were given oral radioiodine.

150 adults patients with locally advanced or metastatic BRAFV600E mutation-positive, differentiated thyroid carcinoma who are refractory to radioactive iodine and have progressed following prior VEGFR targeted therapy will enter in the trial. Patients will be randomized in a 2:1 ratio to either dabrafenib plus trametinib or placebo. Patients will be stratified by number of prior VEGFR targeted therapy (1versus2) and prior lenvatinib treatment (yes versus no)

The goal of this study is to evaluate combined radioactive iodine (RAI, 131-I) and external beam radiotherapy (XRT) to optimize the radiation dose delivered to treat well differentiated thyroid cancers (DTC) with iodine-avid metastases. The investigators hypothesize that precise dosimetric planning will permit this combined RAI-XRT radiotherapeutic approach to be safe and permit higher tumor radiation doses than could otherwise be delivered. Patients with metastatic well-differentiated DTC) that is not completely resectable with macroscopic invasion of tumor into cervical soft tissues and/or non-resectable distant metastases, are the target study population. The primary objective is to evaluate safety as defined by the incidence of maximum grade 3 or greater NCI CTCAE toxicity observed during the treatment period and for the first 30 days following completion of radiotherapy. Secondary endpoints will evaluate efficacy at 6 months and feasibility of this combination to deliver a minimum cumulative dose of 80 Gy to the index tumors selected prior to treatment initiation. The investigators plan to enroll 48 subjects at an accrual rate of 1 subject per month over a study duration of 4 years.

The aim of this study is to test the hypothesis that the quality of recovery with topical lidocaine is better than placebo.

This study will be a non-randomized pilot trial using Cyclophosphamide and Sirolimus for the treatment of metastatic differentiated thyroid cancer. Patients will be treated with Sirolimus 4 mg, PO, days 1-28 as well as Cyclophosphamide 100 mg, PO, days 1-5 and 15-19. Cycle length will be 28 days. Patients will be monitored closely for toxicity and undergo imaging to evaluate efficacy once every 2 cycles.

This is an open-label, multi-center Phase 1/2 study of oral LOXO-292 in pediatric participants with an activating rearranged during transfection (RET) alteration and an advanced solid or primary CNS tumor.

Some tumors are difficult to treat with chemotherapy or radiation. One of the reasons is that areas of the tumor do not have many blood vessels, which makes it difficult for drugs to reach those areas. One way that researchers have recently tried to overcome this problem is by injecting special kinds of bacteria into the tumors. These bacteria have been genetically changed to remove the chemicals that are poisonous to humans, but are still able to cause tumor cells to break down and die. The idea is that these bacteria may be able to assist chemotherapy drugs in fighting cancer. The goal of this clinical research study is to find the highest tolerable dose of one of these bacterial therapies (Clostridium novyi-NT spores) that can be given in combination with pembrolizumab to patients with advanced solid tumors. The safety of this drug will also be studied, as well as whether it can help to control the disease. This is an investigational study. Clostridium novyi-NT is not FDA approved or commercially available. It is currently being used for research purposes only. Pembrolizumab is FDA approved for the treatment of melanoma and different types of head and neck and non-small cell lung cancers. It is investigational to use these drugs in combination with each other in various types of advanced cancers. The study doctor can describe how the study drugs are designed to work. Up to 18 participants will be enrolled in this study. All will take part at MD Anderson.

Thyroid cancers that have spread beyond the neck are not curable. About 30,000 people worldwide die from thyroid cancer every year. Usually, thyroid cancers get worse because the cancer cells become more and more abnormal through a process that is called dedifferentiation. Radioactive iodine is a standard treatment for this type of thyroid cancer. Patients will usually receive multiple dose of radioactive iodine over the course of their cancer journey. Thyroid cancers lose sensitivity to radioactive iodine as the cancer progresses/worsens with the process of dedifferentiation. When this occurs, the radioactive iodine treatments no longer work against the cancer and the cancer grows. Radioactive iodine enters cancer cells through transporter proteins on the outside of the cancer cell. The transporter proteins that are the most important are the sodium iodide symporters. As thyroid cancers dedifferentiate, these symporters stop working as well as they once did. The radioactive iodine can therefore not get into the cancer cells to cause cancer cell death. Laboratory research has shown that in thyroid cancer, a protein on the cell called platelet derived growth factor receptor alpha (PDGFRα) is an important for tumour growth and thyroid cancer dedifferentiation. PDGFRα helps cancer progression and lowers the ability of sodium iodine symporters to move radioiodine into cells where it would normal act to kill the cancer cells. PDGFRα therefore makes thyroid cells resistant to radioactive iodine. Imatinib is an anti-cancer drug that blocks PDGFRα function. It has been used for many years to treat other cancers such as leukemia. The investigators who wrote this study believe that, base on laboratory testing, if thyroid cancer patients are given imatinib whenafter their cancers have become resistant to radioactive iodine, the imatinib will block PDGFRα. This will let the sodium iodine symporters work again and move the radioactive iodine into the cancer cells. This should shrink the tumours. Imatinib would then make the thyroid cancer cell sensitive to radioactive iodine again. This should shrink the tumours and would mean longer control of the cancer, helping people with this disease live longer.
