Active clinical trials for "Astrocytoma"

This phase I trial is studying the side effects and best dose of sorafenib in treating patients with recurrent or progressive malignant glioma. Sorafenib may stop the growth of tumor cells by stopping blood flow to the tumor and by blocking the enzymes necessary for their growth.

This phase I trial is studying the side effects and best dose of oxaliplatin when given together with irinotecan in treating young patients with refractory solid tumors or lymphomas. Drugs used in chemotherapy, such as oxaliplatin and irinotecan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Oxaliplatin may help irinotecan kill more cancer cells by making cancer cells more sensitive to the drug. Giving oxaliplatin together with irinotecan may kill more cancer cells.

This phase II trial is studying how well giving radiation therapy together with temozolomide and lomustine works in treating young patients with newly diagnosed gliomas. Radiation therapy uses high energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide and lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with temozolomide and lomustine after surgery may kill any remaining tumor cells.

In this study an investigational replication-defective, recombinant adenovirus expressing the interferon-beta gene (BG00001) will be directly injected into tumors, in patients with recurrent Grade III and Grade IV Gliomas, in order to deliver the hIFN-beta gene. The purpose of the study is to evaluate the safety and any harmful effects of injection of BG00001 into brain tumors. Also, this study will help determine whether the virus carrying the beta interferon gene will enter brain tumor cells and cause the cancer cells to die. This study will require one hospital admission for the actual procedure of drug administration. All other visits will be conducted on an out-patient basis

RATIONALE: Current therapies for children with low grade astrocytomas that have not responded to standard therapy provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of children with low grade astrocytomas that have not responded to standard therapy PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on children (> 6 months of age) with low grade astrocytomas that has not responded to standard therapy.

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 more than one drug with radiation therapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy in treating patients who have newly diagnosed anaplastic astrocytoma.

RATIONALE: SU5416 may stop the growth of astrocytoma or glioma by stopping blood flow to the tumor. PURPOSE: Phase I/II trial to study the effectiveness of SU5416 in treating patients who have recurrent astrocytoma or mixed glioma that has not responded to previous radiation therapy.

This is a multi-center, open-label, dose escalation study to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, and maximum tolerated dose (MTD) of QBS10072S in patients with advanced or metastatic cancers with high LAT1 expression. The MTD of QBS10072S will be confirmed in patients with relapsed or refractory grade 4 astrocytoma.

Increasing preclinical and clinical data have shown that myeloid-derived suppressor cells (MDSCs) may represent a significant driver of immunosuppression in glioblastoma (GBM, grade IV astrocytoma) and a potential mechanism of treatment resistance to chemoradiotherapy. Tadalafil, an FDA-approved drug with inexpensive cost and excellent safety profile, has been shown to effectively reduce MDSCs and restore T-cell activation in the peripheral blood and in the tumor microenvironment. The purpose of this study is to investigate the impact of targeting MDSCs in newly diagnosed IDH-wildtype grade III-IV astrocytoma by combining tadalafil with standard of care radiation therapy (RT) and temozolomide (TMZ).

Background: A glioblastoma is a tumor in the brain. It is treated with surgery, chemotherapy and radiation therapy. However, most people s tumors come back after therapy. When the tumor grows back, surgery or chemotherapy may not be possible or may no longer work. Repeat radiation therapy or re-irradiation, is an option for treating these tumors when they regrow. Objective: To find out the safety and highest tolerated dose of re-irradiation for people who have recurrent glioblastoma. Eligibility: People ages 18 50 who have glioblastoma that has been treated with radiation but has regrown. Design: Participants will be screened with: Medical history Physical exam MRI of the brain: They will lie in a machine that takes pictures of the brain. Participants will have baseline tests before they start therapy. These will include: Blood tests Neuropsychological tests: These test things like memory, attention, and thinking. Quality of life questionnaire Eye and hearing tests Participants will get a CT of the brain prior to radiation start in order to plan the radiation treatment. Once the plan is completed, they will receive radiation once a day Monday Friday for a total of 10 17 treatments. They will lie on their back for about 10 minutes while they get the treatment. Participants will be monitored for side effects. After they finish treatment, participants will have visits 1, 2, and 3 months later. Then they will have them every 2 months for 3 years. These will include: Medical history Physical exam Blood tests MRI of the brain. Quality of life questionnaire Neuropsychological tests (at some visits) After 3 years, participants will be contacted by phone each month.
