Active clinical trials for "Glioblastoma"

The purpose of the study is to evaluate the feasibility and safety of intra-tumor and interstitial therapy with hBMP4 in increasing doses in patients with progressive and/or multiple recurrent Glioblastoma multiforme (GBM).

Glioblastomas (GBM) are rare tumors of poor prognosis and their treatment is based on surgery followed by radiochemotherapy. Clinical and imaging evaluation is not always straightforward: the more or less complete surgery, the pseudo-progression after radiochemotherapy, the radionecrosis, the diagnosis of the relapse and the follow-up under anti-angiogenic can pose problems Clinicians and radiologists. Accessibility to a plasma tumor molecular marker would greatly facilitate the follow-up of these patients. It is now established for many cancers that circulating tumor DNA (cTNA) has the same molecular abnormalities as those identified in the primary tumor cells. Numerous studies have shown the prognostic value and diagnosis of the exploration of cDNA.

Prospective, open-labeled, multicenter cohort trial for validation of the role of levetiracetam as a sensitizer of temozolomide in the treatment of newly diagnosed glioblastoma patients.

This is non-randomized phase 2 study to assess efficacy and toxicity of long term high dose vitamin D3 given concurrently with chemo-radiotherapy (CCRT) containing temozolomide followed by adjuvant chemotherapy (ACT) with temozolomide in patients with newly diagnosed glioblastoma multiforme GBM). Preoperative diagnosis of GBM will be based on magnetic resonance imaging (MRI) brain scan. All patient will underwent craniotomy with partial or total resection of a visible tumour mass. All patients will be planned for postoperative three-dimensional conformal RT (3-DCRT) or intensity-modulated RT (IMRT) to residual tumour and/or resection bed. A total RT dose of 54-60 Gy will be delivered using 2 Gy daily fractions given over 5 days a week. Daily chemotherapy with temozolomide in the dose of 75 mg/m2/day will be started at the first day of RT, and will be continued for entire period of RT inclusive week-end breaks. ACT will contain 6 cycles of oral temozolomide 150-200 mg/m2/day given for 5 days every 4 weeks. Oral vitamin D3 will be administered in daily dose of 4000 IU. Vitamin D3 therapy will be started 1 week prior to commencing CCRT, and will be terminated immediately after completing last cycle of ACT. MRI scan of the brain will be performed at 4 months after completing CCRT, and than will be repeated every 4 months for first 2 years, and every 6 months for subsequent years. The study participants will be followed until disease progression or death. The study is expected to complete within 4 years.

This study is designed to evaluate the impact of radiotherapy target volume delineation based on AA-PET compared to target volume delineation based on contrast enhanced T1 weighted MRI (T1Gd-MRI) on the clinical outcome of patients with recurrent glioblastoma (GBM) as well as concerning therapeutic safety of the respective strategy.

Rationale: In light of the demonstrated activity of anti-angiogenesis agents in rGBM, it is reasonable to postulate that adding these agents to standard RT and chemotherapy in the up-front management of newly diagnosed GBM may improve the clinical benefit. This study will examine the safety and tolerability of adding CT-322 to the standard radiation therapy/temozolomide (RT/TMZ) backbone of treatment for newly diagnosed GBM

The primary objective of this study is to determine the 6-month Progression free survival (PFS) when intravenous (IV) AR-67 is administered in adults with confirmed recurrence of GBM who have not recently (> 90 days) recurred after treatment bevacizumab (including patients who've received temazolamide, but no bevacizumab). The primary objective in the rapid bevacizumab failure group (< 90 days) is to determine the 2-month PFS.

This study will test the hypothesis that prolonged adjuvant Temozolomide (TMZ) may delay relapses in patients with glioblastoma compared to the standard care consisting in observation with brain MRI every 3 months and rechallenging with TMZ at relapse (Stop and Go arm).

RATIONALE: CT-322 may stop the growth of glioblastoma multiforme by blocking blood flow to the tumor. Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving CT-322 together with irinotecan may kill more tumor cells. PURPOSE: This phase 2 trial is studying the side effects, tolerability, and efficacy of CT-322 when given alone and in combination with irinotecan to patients with glioblastoma multiforme.

The purpose of this access protocol is to allow patients with brain tumors who had previously received 125I-MAB 425 to receive additional course(s) of 125I-MAB 425 until their brain tumor begins to grow, they develop side effects to the treatment, or their medical condition changes (e.g., you become pregnant, become infected with human immunodeficiency virus (HIV) or develop another cancer).
