Active clinical trials for "Glioblastoma"

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy in higher doses over a shorter period of time may kill more tumor cells and have fewer side effects. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether standard radiation therapy, higher-dose radiation therapy, or chemotherapy is more effective in treating older patients with glioblastoma multiforme. PURPOSE: This randomized phase III trial is studying standard radiation therapy to see how well it works compared with higher-dose radiation therapy or chemotherapy in treating older patients with glioblastoma multiforme.

Significant activity (radiographic response rates of approximately 60%) has recently been demonstrated in phase II studies in patients with relapsed GBM from the combined use of Irinotecan (CPT-11) and bevacizumab. The 6-month progression-free survival rate is 30% and median survival duration is 9 months. The current first line therapy of GBM patients following initial surgical resection/debulking is the concomitant use of cerebral radiotherapy and the orally available alkylating agent temozolomide, followed by temozolomide for 6 months post-radiotherapy. Considering the significant activity of the combination of Bevacizumab + irinotecan in patients with recurrent GBM, and considering the activity of temozolomide in GBM, it is proposed that the combination of Bevacizumab + Temozolomide may also be an active regimen. Bevacizumab + Temozolomide display non-overlapping toxicity clinically and thus their combined use without significant dose-reductions seems rational. The toxicity from the combined use of the two drugs prior to radiotherapy, as well as the toxicity when administered together with radiotherapy, is evaluated. This study will try to identity whether Bevacizumab and Irinitecan or Bevacizumab and Temozolomide should be the experimental arm in future phase III comparison with standard care with concomitant Temozolomide and radiotherapy.

This is a phase II study of APG101 + reirradiation (RT) versus reirradiation. Patients suffering from a malignant brain tumor called glioblastoma having a first or second progression can be included. They will be randomized to RT or RT + APG101. APG101 is a fusion protein (similar to an antibody) and will be administered as a weekly infusion. Patients can stay in this study as long as they benefit from the participation (no fixed end). In this trial, 30-35 sites in Germany, Austria and Russia take part.

RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high energy x-rays to kill tumor cells. Giving everolimus together with temozolomide and radiation therapy may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with temozolomide and radiation therapy and to see how well it works in treating patients with newly diagnosed glioblastoma multiforme.

This is a study of multiple regimens of single-agent XL184 in subjects with grade IV astrocytic tumor in first or second relapse. The Randomized Phase of the study will evaluate the safety, tolerability, and preliminary efficacy of four XL184 dosing regimens in separate study arms. Subjects will be randomized to one of the study arms, which will not be blinded. After the Randomized Phase, additional subjects will be enrolled to further expand one study arm in the Expansion Phase.

This phase I trial studies the side effects and best dose of gamma-secretase/Notch signalling pathway inhibitor RO4929097 (RO4929097) when given together with temozolomide and radiation therapy in treating patients with newly diagnosed malignant glioma. Enzyme inhibitors, such as gamma-secretase/Notch signalling pathway inhibitor RO4929097, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving gamma-secretase/Notch signalling pathway inhibitor RO4929097 together with temozolomide and radiation therapy may kill more tumor cells.

This phase I/II trial studies the side effects and best dose of temsirolimus when given together with perifosine and to see how well it works in treating patients with recurrent or progressive malignant glioma. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as perifosine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving temsirolimus with perifosine may be an effective treatment for malignant glioma.

The prognosis of patients with newly diagnosed glioblastoma is dismal despite recent therapeutic improvements Using standard therapy with temozolomide (TMZ) and radiotherapy (60 Gy), the median overall survival time (mOS) is 14.6 months (Stupp et al., 2005). Since in a previous non-randomized bicentric phase II trial, primary combination chemotherapy with lomustine (CCNU) and TMZ was highly effective (mOS 23 months; UKT-03 trial; Herrlinger et al., 2006; Glas et al., 2009) the proposed trial further investigates the efficacy of CCNU/TMZ in a randomized multicenter phase III setting against standard therapy. In case the projected phase III trial confirms the phase II data, CCNU/TMZ combination would be significantly better than TMZ monotherapy and would thus be the new standard treatment for newly diagnosed GBM patients with a methylated MGMT promotor. Thus, this trial has the potential to profoundly change the standard therapy of this most aggressive brain tumor. Since in the previous trial only patients with a methylated MGMT (mMGMT) promoter had a benefit from CCNU/TMZ (mOS in the mMGMT group 34 months, in the non-mMGMT group 12.5 months; Glas et al., 2009) while patients with a non-methylated MGMT did not have any benefit, the trial is restricted to mMGMT patients.The CeTeG trial randomizes in a 1:1 fashion newly diagnosed GBM patients (18-70 years) for either standard TMZ therapy (concomitant and 6 courses à 4 weeks of adjuvant TMZ therapy) or experimental CCNU/TMZ therapy (6 courses à 6 weeks). Both arms include standard radiotherapy (RT) of the tumor site (30 x 2 Gy). Assuming that CCNU/TMZ therapy increases the median overall survival (mOS) from 48.9% (standard TMZ) to 70% (CCNU/TMZ; 75% in the previous phase II trial, Glas et al., 2009), 2 x 68 patients have to be accrued. Patients will be accrued over 24 months and each patient will be followed for at least 24 months adding up to a total minimal duration of the time from first patient in until the end of the follow-up time of 48 months. The primary endpoint is overall survival; secondary endpoints include progression-free survival, response rate, acute and late toxicity, and quality of life.

Sunitinib seems to be a promising treatment for the objective of this proposal: to evaluate the clinical activity of Sunitinib as first line therapy in patients who have measurable disease and to evaluate the safety of Sunitinib with radiation therapy.

In the last 20 years, only temozolomide has obtained indication for the treatment of High-grade glioma (HGG). Temozolomide during and later radiation therapy has doubled one year survival and is the standard treatment for glioblastoma. But 30% of glioblastomas receive only a biopsy as they can't be resected and don't get benefit from this treatment. They and should be treated immediately after the biopsy to prevent neurological deterioration but in spite of this approach they often deteriorate neurologically during radiotherapy. . An effective pre-radiation treatment should improve their prognosis and allow them to complete concomitant radiotherapy and temozolomide treatment. Bevacizumab in recurrent HGG displays 63% of objective responses when combined with irinotecan. But irinotecan is not the most active treatment in this disease. We propose a phase II, two arms, open label, randomized, multicentric study with 2 cycles of temozolomide before radiation therapy and concomitant temozolomide, in patients with glioblastoma and 'biopsy-only'. Bevacizumab will be added to one arm.
