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.

In this phase II study, we investigate clinical outcomes and tolerability of hypofractionated radiotherapy (HRT) combined with temozolomide (TMZ) to treat elderly patients with glioblastoma (GBM).
Glioblastoma multiforme (GBM) is the most aggressive primary tumour within the brain as well as the most common and lethal cerebral cancer, mainly because of treatment failure. Indeed, tumour recurren...
Glioblastomas are the most frequently diagnosed and worst primary malignancy of the central nervous system, with very poor prognosis. The first-line anti-glioma drug temozolomide shows decreasing ther...
The purpose of the study is to investigate the efficacy of combined treatment with temozolomide (TMZ) and metformin for glioblastoma (GBM) in vitro and in vivo.
Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle.

An alkylating agent of value against both hematologic malignancies and solid tumors.
4-Methyl derivative of LOMUSTINE; (CCNU). An antineoplastic agent which functions as an alkylating agent.
A malignant form of astrocytoma histologically characterized by pleomorphism of cells, nuclear atypia, microhemorrhage, and necrosis. They may arise in any region of the central nervous system, with a predilection for the cerebral hemispheres, basal ganglia, and commissural pathways. Clinical presentation most frequently occurs in the fifth or sixth decade of life with focal neurologic signs or seizures.
A TGF-beta subtype that was originally identified as a GLIOBLASTOMA-derived factor which inhibits the antigen-dependent growth of both helper and CYTOTOXIC T LYMPHOCYTES. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta2 and TGF-beta2 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
