Active clinical trials for "Glioblastoma"

The objective of this study was to evaluate the effect of several ophthalmologic prophylactic treatment strategies for the management of ocular side effects (OSEs) in participants with epidermal growth factor receptor (EGFR)-amplified glioblastoma (GBM) who were being treated with depatuxizumab mafodotin (ABT-414).

Phase I/II trial in which participants with recurrent glioblastoma will receive a combination of tumor treating fields(portable device), nivolumab with or without ipilimumab.

The NeAT Glio trial will evaluate whether the addition of ipilimumab prior to the current standard treatment of surgery and chemoradiotherapy will improve survival in patients with newly diagnosed glioblastoma.

Rationale: Glioblastoma (GM) is the most frequent incurable adult brain tumor with median survival of 15 months after diagnosis, despite extensive treatment with surgery, radiation therapy and chemotherapy. Tumor recurrence is inevitable after which life prolonging therapies are no longer available. The development of new treatments for GM is being hampered by inter-and intratumoral heterogeneity of tumors and their microenvironment, which currently cannot be predicted accurately with current diagnostics. Objective: To establish primary patient derived organoid cultures from GM to study mechanisms that contribute to aggressive tumor growth and treatment resistance in primary and recurrent GM. Study design: Preclinical study, using patient derived glioblastoma tissue. Study population: Patients 18 years or older, with newly diagnosed glioblastoma. Main study parameters/endpoints: Intra-and inter organoid genetic and epigenetic heterogeneity that is representative for GM. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Minimal burden, since the biopsies are part of a regular neurosurgical procedure (debulking); which intends to eradicate the macroscopical tumorload in order to optimize survival benefit. The tissue (biopsy) that will be used for this trial is part of the tumor tissue that is resected during the standard debulking. Benefit: no benefit for the patient.

There are preliminary studies that suggest that radiation therapy to areas of the brain containing cancer stem cells (in addition to the area where the tumor was surgically treated) may help patients with high-grade brain tumors live longer. The purpose of this study is to determine whether the addition of stem-cell radiation therapy to the standard chemoradiation will further improve the outcome. The investigators will collect information about the patient's clinical status, disease control, neurocognitive effects, and quality of life during follow-up in our department. The purpose of the study is to improve the overall survival patients with newly diagnosed malignant brain tumors treated with stem cell radiation therapy and chemotherapy. The investigators will also measure how patients treated with this novel method of radiation therapy do over time in terms of disease control, potential neurocognitive side effects, overall function, and quality of life.

The study assessed the safety and the dose of the combination of INC280 and buparlisib (BKM120), as well as the anti-tumor activity of the combination, in patients with recurrent glioblastoma with PTEN mutations, homozygous deletion of PTEN or PTEN negative by IHC. In addition, the anti-tumor activity of INC280 single agent should have been assessed in patients with recurrent glioblastoma with c-Met alteration.

This is an open-label, multicenter, Phase 2 study to evaluate the efficacy and safety of oral selinexor in participants with recurrent gliomas.

The purpose of the study is to determine the effectiveness of an investigational drug called lucanthone, when combined with temozolomide (TMZ) and radiation in the treatment of Glioblastoma Multiforme (GBM).

Background: - Glioblastoma is an aggressive type of brain cancer that often resists treatment. TRC105 is an experimental drug that blocks the growth of new blood vessels. It is being studied for possible use in treating different kinds of cancer. Researchers want to see if TRC105 can be used to treat glioblastoma that has not responded to standard treatments. Objectives: - To test the safety and effectiveness of TRC105 in adults who have glioblastoma that has not responded to standard treatments. Eligibility: - Individuals at least 18 years of age who have glioblastoma that has not responded to standard treatments. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies and other tests will be used to study the tumor before the start of treatment. Participants will have 28-day (4-week) cycles of treatment. Participants will have TRC105 intravenously once a week. The first infusion will take about 4 hours. The length of time needed for the infusion may be slowly reduced if it is well tolerated. At the end of the first cycle (the first 4 weeks), the imaging studies will be repeated before continuing TRC105. Participants will take TRC105 for as long as the tumor does not grow and the side effects are not too severe. They will have imaging studies at the end of every cycle to evaluate the tumor.

In the current proposed trial the role of the low-dose WBRT (0.15 Gy) would be to safely treat the microscopic distant GBM cells outside of the high dose RT region and sensitize the gross tumor, while the focal radiation dose (1.85 Gy) to the gross tumor will bring the total tumor dose of 2 Gy per fraction which is the standard of care. Radiotherapy (RT) has been integral in the treatment of GBM since the 1970s when Walker et al. showed that post-operative whole brain radiotherapy (WBRT) offered significant improvements in median survival time, and even more so when given with concomitant BCNU chemotherapy. Ensuing dose escalation studies found the optimal dose to be 60 Gy. Patients could not tolerate escalation to higher doses than 60 Gy with WBRT due to unacceptable toxicity. Even with WBRT of 60 Gy, a huge volume of healthy brain tissue was unnecessarily treated with high-dose radiation; recurrences with WBRT remained overwhelmingly local. Hochberg and Pruitt (1980) found that after WBRT only 3% of recurrences were outside 2 cm of the margins of the primary tumor. With the rise of the CT scan in the 1980s and the MRI in the 1990s, along with subsequent improvements in three-dimensional conformal radiation, partial brain RT (PBRT) became practical since tumor margins could be visualized and irradiated more accurately. - Subsequently, WBRT was shown to provide no survival benefit over PBRT at the same dosage; - thus, the latter took over as the standard of care.
