Active clinical trials for "Glioblastoma"

Clinical Part: The objective of this study is to determine the efficacy and safety of SUTENT in patients with recurrent or progressive glioblastoma multiforme.Patients with tissue based diagnosis of intracranial glioblastoma multiforme, above 18 years of age and of both genders, who have a first tumor recurrence or progress after surgery, radiation- and chemotherapy will be included. The hypothesis is that SUTENT will significantly increase the progression free survival rate at 6 months in the study population.

The purpose of this study is to evaluate the safety and effectiveness of 131I-TM601 in the treatment of adult patients with progressive or recurrent malignant gliomas.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of carmustine in treating patients who have progressive or recurrent glioblastoma multiforme.

This is a single-institution, open-label, early-phase study to assess the ability of ribociclib (LEE011) to inhibit CDK4/CDK6/Rb/E2F signaling and cell proliferation/viability in core and infiltrating tumor tissues obtained from patients with recurrent glioblastoma or anaplastic glioma compared to the baseline/primary pathologic tumor specimen. Abundant preclinical evidence indicates that Rb-deficient cancer cells are resistant to CDK4/6 inhibition and ongoing trials with CDK4/6 inhibitors exclude patients with Rb-deficient tumors. The investigators will evaluate 10 patients with Rb-positive glioblastoma or anaplastic glioma in this study. Given that a minority of glioblastomas ha Rb loss the investigators anticipate enrolling a maximum of 20 patients, to meet our goal of 10 patients with Rb-positive tumors.

The combination therapy of temozolomide and radiation has been established as the standard therapy for the initial treatment of glioblastoma. However, the prognosis for patients with recurrent/ refractory glioblastoma is dismal, with a median survival of 3~6 months. There is no efficient and standard care at the time of recurrence or progression following temozolomide administration. Recently, many clinicians have reassessed the efficacy of second-line chemotherapeutic agents such as nitrosoureas for the treatment of recurrent/refractory glioblastoma. It is very important that the effect of the agent is sustained and the adverse effect is reduced to preserve the quality of life in recurrent settings. We have realized that the clinical features of Korean patients are very different from those of foreign patients. Therefore, it is mandatory to develop the new strategy for the treatment of Korean patients. We modify the PCV chemotherapy in the dose and administration schedule of CCNU and procarbazine to reduce the side effect, especially hematologic problems. The dose of CCNU is reduced to 75mg/m2 and the interval between CCNU and procarbazine is increased. Moreover, vincristine is excluded because BBB permeability of vincristine is very poor and the risk of neurotoxicity is high. We introduce the modified PC chemotherapy regimen for the treatment of recurrent/refractory glioblastoma, which is the first multicenter trial for glioblastoma patients in Korea.

The purpose of the study is to determine the safety and efficacy of intracranially implanted Carmustine in the treatment of patients with recurrent malignant glioma.

The study will investigate combined radiotherapy and immunotherapy on malignant gliomas. Immune adjuvants will be injected intratumorally and systemically to induce antitumor-specific immunity after radiation induced immunological tumor cell death (ICD). With radiation, tumor cells release tumor antigens that are captured by antigen presenting dendritic cells. Immune adjuvants promote the presentation of tumor antigens and the priming of antitumor T lymphocytes. The combined treatment induces and amplifies the specific antitumor immunity in patients with malignant gliomas, prolonging survivals of patients.

Neuro-oncological trials may fail due to the drug never getting to the intended target (i.e. within the tumor micro environment). Also, changes' occurring in tumor cells when removed from patients and grown in-vitro is another limiting factor influencing the clinical success. Important questions are therefore: Does the drug get there? Does the drug do what it is intended to do? To improve chances of clinical success there is a need for rational and intelligent selection of potential drugs in future trials. This is an initiative for analyzing tumor concentration of preoperative administered repurposed drugs

Glioblastoma is the most common and the most aggressive primary brain cancer in adults. Indeed, despite very intensive treatments (i.e. maximal safe surgery, radiotherapy and several lines of cytotoxic chemotherapies), inducing significant adverse events, the prognosis of glioblastoma patients remains dismal with a median overall survival of ~15 months. Therefore, more efficient and less toxic therapies are urgently needed to improve survival and quality of life of glioblastoma patients. The oncolytic virus TG6002 has shown efficacy and good safety profile in several preclinical models of glioblastoma in vitro (i.e. cell line) and in vivo (i.e. xenografts in Swiss/Nude mice). Comprehensive toxicology studies of TG6002/Flucytosine have been completed in rabbits and monkeys supporting safety investigations of TG6002/Flucytosine in human patients. Taken these data all together, TG6002/Flucytosine appears as a very promising therapeutic strategy in glioblastoma patients that merits consideration for early phase clinical trial.

The purpose of this study is to determine whether a combination of Sunitinib, Temozolomide and Radiation Therapy would be effective in the treatment of newly diagnosed Glioblastoma patients harboring tumors with unmethylated MGMT promoter.
