NCT ID: NCT02022384 Completed - Clinical trials for Glioblastoma Multiforme

Immunophenotyping From Blood of Patients With Malignant Gliomas

Start date: December 2013
Phase:
Study type: Observational

In this explorative study immunological changes during tumor therapy will be analyzed in patients with malignant glioma. Immunophenotyping before and during therapy is used as analysis method. Thereby immune cells are quantitatively and qualitatively detected from patient's blood at continuous time points. Additionally relevant mediators like cytokines, danger signals and chemokines are analyzed by other methods. Obtained results may give information about the effects of therapy on immunological processes and immune cells and may help to find immunological based predictive or prognostic tumor markers and to define time points for including additional immune therapy in the future.

NCT ID: NCT01985256 Completed - Clinical trials for Glioblastoma Multiforme

Study of a Retroviral Replicating Vector Given Intravenously to Patients Undergoing Surgery for Recurrent Brain Tumor

Start date: February 2014
Phase: Phase 1
Study type: Interventional

This is a multicenter study evaluating the safety and tolerability of Toca 511 administered intravenously to patients with recurrent or progressive Grade III or Grade IV Gliomas who have elected to undergo surgical removal of their tumor. Patients meeting all of the inclusion and none of the exclusion criteria will receive an initial dose of Toca 511 administered as an intravenous, bolus injection, followed approximately 11 days later by an additional dose injected into the walls of the resection cavity at the time of planned tumor resection. Approximately 6 weeks later, patients will begin treatment with oral Toca FC, an antifungal agent, and repeated every 4 weeks. All patients enrolled in this study will be encouraged to participate in a continuation protocol that enables additional Toca FC administration and the collection of long-term safety and response data.

NCT ID: NCT01975116 Completed - Glioblastoma Clinical Trials

p28 in Treating Younger Patients With Recurrent or Progressive Central Nervous System Tumors

Start date: August 2013
Phase: Phase 1
Study type: Interventional

This phase I trial studies the side effects and best dose of azurin-derived cell-penetrating peptide p28 (p28) in treating patients with recurrent or progressive central nervous system tumors. Drugs used in chemotherapy, such as azurin-derived cell-penetrating peptide p28, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

NCT ID: NCT01967758 Completed - Clinical trials for Glioblastoma Multiforme

Phase I Study of Safety and Immunogenicity of ADU-623

Start date: January 8, 2014
Phase: Phase 1
Study type: Interventional

This is a study for patients with brain tumors called astrocytic tumors. The study will enroll patients who have received standard treatment. The study will test a vaccine called ADU-623. ADU-623 has not been tested in humans before, so the goal of this study is to see if ADU-623 can be given safely to brain cancer patients and what is the better dose to give patients among the three doses that planned to be tested. This study will also evaluate the length of time before patients' cancer worsens and if ADU-623 helps patients to live longer. The study will also measure the body's immune system response to ADU-623.

NCT ID: NCT01922076 Completed - Glioblastoma Clinical Trials

Adavosertib and Local Radiation Therapy in Treating Children With Newly Diagnosed Diffuse Intrinsic Pontine Gliomas

Start date: September 3, 2013
Phase: Phase 1
Study type: Interventional

This phase I trial studies the side effects and the best dose of adavosertib when given together with local radiation therapy in treating children with newly diagnosed diffuse intrinsic pontine gliomas. Adavosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays, gamma rays, neutrons, protons, or other sources to kill tumor cells and shrink tumors. Giving adavosertib with local radiation therapy may work better than local radiation therapy alone in treating diffuse intrinsic pontine gliomas.

NCT ID: NCT01884740 Terminated - Clinical trials for Glioblastoma Multiforme

Intraarterial Infusion Of Erbitux and Bevacizumab For Relapsed/Refractory Intracranial Glioma In Patients Under 22

Start date: June 2013
Phase: Phase 1/Phase 2
Study type: Interventional

Central nervous system (CNS) malignancies are the second most common malignancy and the most common solid tumor of childhood, including adolescence. Annually in the United States, approximately 2,200 children are diagnosed with CNS malignancy and rates appear to be increasing. CNS tumors are the leading cause of death from solid tumors in children. Survival duration after diagnosis in children is highly variable depending in part on age at diagnosis, location of tumor, and extent of resection; however, most children with high grade glioma die within 3 years of diagnosis. All patients with high grade glioma experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). We have shown in previous phase I trials that a single Superselective Intra-arterial Cerebral Infusion (SIACI) of Cetuximab and/or Bevacizumab is safe for the treatment of recurrent glioblastoma multiforme (GBM) in adults, and we are currently evaluating the efficacy of this treatment. Therefore, this phase I/II clinical research trial is an extension of that trial in that we seek to test the hypothesis that intra-arterial Cetuximab and Bevacizumab is safe and effective in the treatment of relapsed/refractory glioma in patients <22 years of age. We expect that this project will provide important information regarding the utility of SIACI Cetuximab and Bevacizumab therapy for malignant glioma in patients <22 years of age and may alter the way these drugs are delivered to our patients in the near future.

NCT ID: NCT01861990 Withdrawn - Glioblastoma Clinical Trials

Valproic Acid in Childhood Progressive Brain Tumors

Start date: May 2013
Phase: Phase 1
Study type: Interventional

The study investigates valproic acid added to radiation and temozolomide therapy (standard of care) for progressive or recurrent pediatric brain tumors.

NCT ID: NCT01849952 Recruiting - Glioblastoma Clinical Trials

Evaluating the Expression Levels of MicroRNA-10b in Patients With Gliomas

Start date: February 28, 2020
Phase:
Study type: Observational

MicroRNAs (miRNA) are molecular biomarkers that post-transcriptionally control target genes. Deregulated miRNA expression has been observed in diverse cancers. In high grade gliomas, known as glioblastomas, the investigators have identified an oncogenic miRNA, miRNA-10b (mir-10b) that is expressed at higher levels in glioblastomas than in normal brain tissue. This study tests the hypothesis that in primary glioma samples mir-10b expression patterns will serve as a prognostic and diagnostic marker. This study will also characterize the phenotypic and genotypic diversity of glioma subclasses. Furthermore, considering the critical function of anti-mir-10b in blocking established glioblastoma growth, the investigators will test in vitro the sensitivity of individual primary tumors to anti-mir-10b treatment. Tumor, blood and cerebrospinal fluid samples will be obtained from patients diagnosed with gliomas over a period of two years. These samples will be examined for mir-10b expression levels. Patient survival, as well as tumor grade and genotypic variations will be correlated to mir-10b expression levels.

NCT ID: NCT01837862 Recruiting - Clinical trials for Glioblastoma Multiforme

A Phase I Study of Mebendazole for the Treatment of Pediatric Gliomas

Start date: October 22, 2013
Phase: Phase 1/Phase 2
Study type: Interventional

This is a study to determine the safety and efficacy of the drug, mebendazole, when used in combination with standard chemotherapy drugs for the treatment of pediatric brain tumors. Mebendazole is a drug used to treat infections with intestinal parasites and has a long track record of safety in humans. Recently, it was discovered that mebendazole may be effective in treating cancer as well, in particular brain tumors. Studies using both cell cultures and mouse models demonstrated that mebendazole was effective in decreasing the growth of brain tumor cells. This study focuses on the treatment of a category of brain tumors called gliomas. Low-grade gliomas are tumors arising from the glial cells of the central nervous system and are characterized by slower, less aggressive growth than that of high-grade gliomas. Some low-grade gliomas have a more aggressive biology and an increased likelihood of resistance or recurrence. Low-grade gliomas are often able to be treated by observation alone if they receive a total surgical resection. However, tumors which are only partially resected and continue to grow or cause symptoms, or those which recur following total resection require additional treatment, such as chemotherapy. Due to their more aggressive nature, pilomyxoid astrocytomas, even when totally resected, will often be treated with chemotherapy. The current first-line treatment at our institution for these low-grade gliomas involves a three-drug chemotherapy regimen of vincristine, carboplatin, and temozolomide. However, based on our data from our own historical controls, over 50% of patients with pilomyxoid astrocytomas will continue to have disease progression while on this treatment. We believe that mebendazole in combination with vincristine, carboplatin, and temozolomide may provide an additional therapeutic benefit with increased progression-free and overall survival for low-grade glioma patients, particularly for those with pilomyxoid astrocytomas. High grade gliomas are more aggressive tumors with poor prognoses. The standard therapy is radiation therapy. A variety of adjuvant chemotherapeutic combinations have been used, but with disappointing results. For high-grade gliomas this study will add mebendazole to the established combination of bevacizumab and irinotecan to determine this combinations safety and efficacy
