Active clinical trials for "Sarcoma"

Ewing sarcoma is characterized by genomic rearrangements resulting in over-expression of ets family transcription factors driving tumor progression. TK216 is designed to inhibit this effect by inhibiting downstream effects of the EWS-FLI1 transcription factor. This study is a first in human study of TK216 in subjects with Ewing sarcoma. The study is designed to establish initial safety and efficacy data in monotherapy and in combination with vincristine to assess the potential of TK216 for further development.

Alveolar soft part sarcoma (ASPS), a rare subset of STS (<1%) harbors t(X;17)(p11;q25) translocation and produces resultant ASPL-TFE3 fusion protein. Due to its nature of high expression of angiogenic factors, sunitinib and cediranib produced overall response rates of 55% and 43%, respectively. However, the efficacy of pazopanib is unknown in metastatic ASPS.

Methotrexate is one of the most effective chemotherapy drugs in the treatment of osteosarcoma and some other types of bone sarcoma which are treated the same way as osteosarcoma. However, it frequently leads to sore mouth, tummy pain and increased risk of developing infections. The investigators try to save or "rescue" normal cells from the side effects of methotrexate by giving a drug called folinic acid. Folinic acid is started 24 hours after methotrexate and given regularly until methotrexate levels are really low and not dangerous to normal cells anymore. Despite this rescue, side effects are still a problem and many patients are not well enough to receive subsequent chemotherapy on time. Almost half of the planned chemotherapy cycles are not given on time due to methotrexate side effects. In this study the investigators will examine if adding a drug called glucarpidase to folinic acid is helpful. Glucarpidase is an enzyme that inactivates methotrexate in the blood stream. Lower methotrexate concentration in the blood stream leads to fewer side effects. The investigators would like to see if glucarpidase helps patients to have their chemotherapy on time, by reducing the side effects of methotrexate.

Background: - Certain types of cancers, including sarcoma and melanoma, have specific antigens (protein molecules) on their surfaces. Research has shown that producing an immune reaction to these antigens may be able to keep tumors from growing by encouraging the immune system to destroy the tumor cells. By creating a vaccine that contains antigens similar to those found on the cancer cells, researchers hope to cause an immune reaction that targets the cancer cells. However, more research is needed to determine the safety and effectiveness of this type of vaccine treatment. Objectives: - To determine whether a tumor cell vaccine, given to individuals who have had surgery to remove malignant tumors from the chest, can cause an immune reaction that will prevent the tumors from coming back. Eligibility: - Individuals at least 18 years of age who have been diagnosed with cancer that has spread to the lungs, pleura, or mediastinum, and have recently had surgery to remove tumors in the chest. Design: Participants will be screened with a physical examination and medical history, as well as blood tests and imaging studies. Participants will have the option to have leukapheresis to collect white blood cells for studies on how the body is responding to the vaccine. Participants who agree to have this procedure will have it before the start of treatment and after the sixth and eighth vaccines. Seven days before the first vaccine, participants will receive the chemotherapy drugs celecoxib and cyclophosphamide to take twice a day at home. Participants will receive the experimental vaccine as an injection in the thigh or arm, and may receive it in two shots depending on how many cells are in each vaccine. Participants will receive a diary to monitor medication doses and side effects, as well as additional cyclophosphamide and celecoxib to take at home as directed by the study. Participants will have one vaccine every month for 6 months, and will have regular blood tests and imaging studies. After the sixth vaccine, participants who have successfully responded to the treatment will have two additional vaccines given 3 months apart. After the eighth vaccine, participants will have followup visits every 3 months for 1 year and then every 6 months for up to 4 years....

Background: - Certain types of lung, esophageal, or thymic cancers and mesotheliomas have specific antigens (protein molecules) on their surfaces. Research studies have shown that giving a vaccine that contains antigens similar to these may cause an immune response, which may keep tumors from growing. Researchers are also interested in determining whether the chemotherapy drug cyclophosphamide and the anti-inflammatory drug celecoxib may help the vaccine work better, particularly in patients with lung cancer. Objectives: - To evaluate the safety and effectiveness of tumor cell vaccines in combination with cyclophosphamide and celecoxib in patients with cancers involving the chest. Eligibility: - Individuals at least 18 years of age who have had surgery for small cell or non-small cell lung cancer, esophageal cancer, thymoma or thymic carcinoma, and malignant pleural mesothelioma. Design: Following recovery from surgery, chemotherapy, or radiation, participants will have leukapheresis to collect lymphocytes (white blood cells) for testing. Participants will receive celecoxib and cyclophosphamide to take twice a day at home, 7 days before the vaccine. Participants will have the vaccine in the clinical center (one or two shots per month for 6 months), and will stay in the clinic for about 4 hours after the vaccine. Participants will keep a diary at home of any side effects from the vaccine, and will continue to take cyclophosphamide and celecoxib. One month after the sixth vaccine, participants will provide another blood sample for testing, and if the tests are satisfactory will return to the clinic every 3 months for 2 additional vaccines. Participants will return to clinic for follow-up physical examinations, lab tests, and scans every 3 months for 2 years and then every 6 months for up to 3 years.

The purpose of this study is to examine if a short-term treatment with pazopanib, an oral drug inhibiting the growth of blood vessel, can reduce the metabolism of soft-tissue sarcomas and thus facilitate their resection when given prior to surgery. Moreover, the study assesses the prognostic and predictive value of several new biomarkers (endothelial progenitor cells, soluble vascular epithelial growth factor),

This randomized phase III trial is studying gemcitabine hydrochloride, docetaxel, and bevacizumab to see how well they work compared with gemcitabine hydrochloride, docetaxel, and a placebo in treating patients with advanced or recurrent uterine leiomyosarcoma. Drugs used in chemotherapy, such as gemcitabine hydrochloride and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. It is not yet known whether gemcitabine hydrochloride and docetaxel are more effective when given with or without bevacizumab in treating uterine leiomyosarcoma.

RATIONALE: Drugs used in chemotherapy, such as doxorubicin, ifosfamide, and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Chemoprotective drugs, such as dexrazoxane, may protect normal cells from the side effects of chemotherapy. Giving combination chemotherapy together with dexrazoxane before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with dexrazoxane followed by surgery and radiation therapy works in treating patients with advanced soft tissue sarcoma or recurrent bone sarcoma.

RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy before surgery may shrink the tumor so that it can be removed. Giving combination chemotherapy after surgery may kill any remaining tumor cells. PURPOSE: This phase II trial is studying how well surgery and/or combination chemotherapy work in treating children with fibrosarcoma.

This research is being done to find out if adding a drug called Avastin to an already approved regimen used for soft-tissue sarcoma, Doxorubicin, will improve overall survival, and slow disease progression. The study will also evaluate the overall safety of combining these drugs. It is not known if combining these drugs will improve outcome. Avastin has been approved for the treatment of metastatic carcinoma of the colon or rectum. It is not approved for the treatment of soft-tissue sarcoma when added to Doxorubicin.
