Active clinical trials for "Neoplasm Metastasis"

The purpose of this study is to compare the safety and efficacy of masitinib 6 mg/kg/day versus placebo in the treatment of patients with primary progressive multiple sclerosis or relapse-free secondary progressive multiple sclerosis.

The main objective is to compare resection rates (R0 or R1) for hepatic metastases in the experimental arm (tri chemotherapy plus targeted therapy) versus the control arm (bi chemotherapy plus targeted therapy); in both arms the targeted therapy is selected according to K-Ras status of the patient's tumor. The secondary objectives are to evaluate the objective response rate (CR and PR) after 4 cycles of treatment, according the RECIST V1.1 evaluation scale. the rate of complete remission (CR) at 6 months after the last study treatment (hepatic surgery or last chemotherapy cycle). the specific rates of resection R0, R1, R2. the complete pathological response Rate, the relapse-free survival rate in (R0 or R1) resected patients, the response duration in non-resected patients, the toxicity according to CTC AE V4 scale except for the neurotoxicity that will be evaluated with the Levi scale, the post operative complications using the DINDO classification, the progression-free survival (PFS) and overall survival (OS). The objectives of the biological study are: to evaluate tumor-related predictive factors such as somatic mutations (KRAS, BRAF, TP53) and genetic amplification related factors (EGFR), to evaluate patient-related predictive factors in connection with genetic polymorphisms (Fc gamma and VEGF receptors), to evaluate ADCC activity via immunohistochemistry in order to analyze the lympho free and progression-free survival, to study circulating of tumor cells as prognostic factor for metastatic colorectal cancer, non- resectable at presentation.

This randomized, multicenter, double-blind, placebo-controlled study will evaluate the efficacy and safety of onartuzumab (MetMAb) in combination with Tarceva (erlotinib) in participants with incurable non-small cell lung cancer identified to be Met diagnostic-positive. Participants will be randomized to receive either onartuzumab (MetMAb) or placebo in combination with erlotinib. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

The purpose of this study is to assess the efficacy, safety, and tolerability of GRN1005 in patients with brain metastases from breast cancer. For patients with HER2 positive metastatic breast cancer, GRN1005 will be assessed in combination with Trastuzumab (Herceptin®) as per standard-of-care practice. In addition, this study will evaluate the ability of 18F-FLT to determine if the amount of change in the uptake in the brain metastases from breast cancer after GRN1005 treatment, correlates with intra-cranial response (for patients enrolled at NCI).

Evaluates the effectiveness of on-label Paricalcitol versus Cinacalcet with Low-Dose Vitamin D.

A pharmacodynamic study to evaluate the effect of AV-299 on exploratory pharmacodynamic markers in subjects with advanced solid tumors who have liver metastases. To evaluate safety and tolerability of AV-299 administered IV in subjects with advanced solid tumors who have liver metastases.

RATIONALE: Video-assisted surgery may have fewer side effects than conventional surgery in patients with lung metastases. It is not yet known whether conventional surgery or video-assisted surgery is more effective in treating lung metastases. PURPOSE: Randomized phase III trial to compare the effectiveness of conventional surgery with that of video-assisted surgery in treating patients who have lung metastases.

Oxaliplatin is an experimental anti-cancer drug that can shrink tumors such as colon cancer. However, because this drug can damage the kidneys, it is necessary to determine what doses of the drug can safely be given to patients with poor kidney function. Patients with advanced cancer, poorly functioning kidneys, and no good standard treatment options are eligible for this study. Candidates will be screened with imaging tests, such as CT and MRI scans, to determine the size and location of the cancer and with blood and urine tests to evaluate kidney and liver function. Study participants will receive oxaliplatin intravenously (through a vein) every 3 weeks for as long as the cancer is under control and there are no serious side effects from the drug. If significant side effects develop, the dosage will be reduced, or the drug will be stopped. Blood tests to measure blood cell counts will be done at least once a week, and CT scans, chest X-rays, and MRIs will be done about once every 6 weeks to assess the tumor's response to the treatment. Additional blood tests will be done at the beginning of the first two treatment cycles to measure the amount of oxaliplatin in the blood, and urine will be collected during the first 24 hours of drug treatment to determine how much drug is eliminated by the body in urine.

This study examines the feasibility of using gene therapy to prevent some of the toxicities of an intensive chemotherapy regimen in patients with metastatic breast cancer. Patients who do not wish to participate in the gene therapy procedures will be offered identical chemotherapy on a different protocol. Patients will be treated initially with chemotherapy which is active against breast cancer, but which has a low potential to hurt blood-forming cells. Then, the patient will receive high dose chemotherapy, during which time blood cells which are capable of rebuilding patients' bone marrows will be removed from the patients' bloodstream. We will use these blood cell collections to isolate peripheral blood progenitor cells (PBPCs), those cells which are thought to be the forbears of all other blood cells. A portion of the PBPCs will be exposed to a disabled virus which either carries genetic material referred to as the multidrug resistance gene (MDR1). The virus will transfer the MDR1 gene into a portion of the patient's PBPCs. The purpose of putting the MDR1 gene into the patients' PBPCs is to try to make these blood cells and their offspring resistant to the toxic effects of certain types of breast cancer chemotherapy. The MDR1 protein (Pgp) that is made from the MDR1 gene makes cells resistant to chemotherapy in laboratory systems by pumping the drug out of cells before the drug is able to kill the cell. Another portion of the patients PBPCs will be exposed to a similar disabled virus carrying a different gene called the NeoR gene. The NeoR gene should not change the effects of chemotherapy on blood forming cells. The purpose of using the NeoR gene is that it will serve as a point of comparison, to see if the presence of the MDR1 drug resistance gene really helps blood forming cells withstand subsequent chemotherapy. Patients are then treated with a very high dose of another anti-breast cancer drug, one that is very toxic to bone marrow cells, and patients will then receive the frozen PBPCs, which contain the new genes, to help them recover from the chemotherapy. After recovery, patients will then be treated with high doses of paclitaxel (Taxol) and doxorubicin (Adriamycin) chemotherapy. Both of these drugs are very active against breast cancer, and the MDR1 gene may potentially protect bone marrow cells against these drugs. Samples of peripheral blood cells will be obtained before each of these doses of chemotherapy to determine whether the number of blood cells that contain the MDR1 gene in comparison to the number that contain the NeoR gene has increased in response to the chemotherapy.

Bolus PSC 833 is administered on Day 1 simultaneously with initiation of 24 hour continuous infusion of PSC 833, followed by another continuous infusion lasting an additional 6 days. To ensure the safety of a 7 day infusion of PSC 833, one patient is treated for 5 days and a second for 6 days, before the first cohort is enrolled. Vinblastine is administered in escalating doses on days 2-5. At least 3 patients are entered at each dose level. The MTD will be defined as the dose immediately below that at which 2 patients experience dose limiting toxicity. Treatment continues every 28 days.
