Active clinical trials for "Glioblastoma"

The objective of this clinical investigation is to assess the safety and performance of the SonoClear Acoustic Coupling Fluid (ACF). The performance will be assessed by analysis of the contrast-to-noise ratio (CNR) and assessment of image quality by using the Surgeon Image Rating (SIR) Scale. This is a prospective, multi-centre single-arm study where the performance of SonoClear ACF relative to routinely used acoustic coupling fluid is investigated by each patient being their own control. Patients with the diagnosis of HGG and LGG at up to 10 sites will be included. Additionally, safety data are collected at 30 days and 6 months post-procedure.

This study is a clinical trial to determine the safety of injecting G207 (a new experimental virus therapy) into a recurrent or progressive brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication and tumor cell killing, will also be tested.

A Phase 1b/2, Multicenter, Open-Label Study of ACP-196 in Subjects with Recurrent Glioblastoma Multiforme (GBM)

Glioblastoma Multiforme is one of the most common, and unfortunately one of the most aggressive brain tumors in adults with most of the patients recurring and dying of the disease with a median survival of 16 months from diagnosis. Current treatment for patients with newly diagnosed Glioblastoma Multiforme (GBM) is safe maximal surgical resection followed by concomitant conventional Radiotherapy (RT) delivered in 6 weeks + Temozolomide (TMZ) followed by TMZ for 6 to 12 cycles. Recent scientific research has shown that Metformin, a common drug used to treat diabetes mellitus, may improve the results of the treatment in patients with a variety of cancers, such as breast, colon, and prostate cancer. Metformin is an attractive and safe medication to be used in this group of patients because of its very low toxicity. In our center the investigators have been using TMZ for 2 weeks prior to a short course (4 weeks) of RT which equivalent to the standard RT of 6 weeks. Temozolomide is used 2 weeks before RT + TMZ, and this is followed by the 6 to 12 cycles of TMZ. Our results are quiet encouraging with a median survival of 20 months, and acceptable toxicity.

This clinical trial evaluates adding high-dose ascorbate (vitamin C) to standard of care treatment of glioblastoma multiforme (a type of brain tumor) in adults. All subjects will receive high-dose ascorbate in addition to the standard treatment.

This phase II trial studies the effects of pembrolizumab on the body, or pharmacodynamics, in patients with glioblastoma that has come back. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This phase I trial studies the side effects and best dose of genetically modified T-cell immunotherapy in treating patients with malignant glioma that has come back (recurrent) or has not responded to therapy (refractory). A T cell is a type of immune cell that can recognize and kill abnormal cells in the body. T cells are taken from the patient's blood and a modified gene is placed into them in the laboratory and this may help them recognize and kill glioma cells. Genetically modified T-cells may also help the body build an immune response against the tumor cells.

This randomized phase II trial studies how well dose-escalated photon intensity-modulated radiation therapy (IMRT) or proton beam radiation therapy works compared with standard-dose radiation therapy when given with temozolomide in patients with newly diagnosed glioblastoma. Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs, such as temozolomide, may make tumor cells more sensitive to radiation therapy. It is not yet known whether dose-escalated photon IMRT or proton beam radiation therapy is more effective than standard-dose radiation therapy with temozolomide in treating glioblastoma.

Patients with newly diagnosed glioblastoma will be consented following tumor resection then undergo leukapheresis for harvest of peripheral blood leukocytes for generation of dendritic cells. Subjects will then receive standard of care (planned 6 weeks) radiation therapy (RT) and concurrent temozolomide (TMZ) at a standard targeted dose of 75 mg/m2/day. The study cycle of TMZ comprises a targeted dose of 150-200mg/m2/day for 5 days every 4 (+2) weeks for up to 12 cycles (patients with unmethylated MGMT gene promoter will receive only cycle 1). All patients will receive up to a total of 10 DC vaccines called pp65 CMV dendritic cells (DC). Dendritic Cell (DC) vaccines #1-3 will be given every two weeks, thus delaying the initiation of TMZ cycle 2 for patients receiving TMZ. All remaining TMZ/vaccine cycles will be 4 (+2) weeks in length. After the first 3 DC vaccines given during Cycle 1 of TMZ, the remaining DC vaccine injections are given on Day 21 (+/- 2 days) of each TMZ cycle. Subjects with unmethylated MGMT will only receive one cycle of adjuvant TMZ; however, their vaccine schedule will follow the same 4 (+ 2) week TMZ cycle schedule. Following RT, patients will be randomized into 1 of 3 groups. Groups 1 and 2 will be blinded. The groups differ in the type of pre-conditioning received prior to DC vaccine #4; additionally, Group 3 will be receiving infusions of varlilumab 7 days prior to and with vaccine #1 and 7 days prior to vaccine #3+. The pre-conditioning for each group is as follows: Group 1: Unpulsed DC pre-conditioning prior to DC vaccine #4; Group 2: Tetanus-diphtheria (Td) pre-conditioning prior to DC vaccine #4; Group 3: Td pre-conditioning prior to DC vaccine #4 and varlilumab infusion at 7 days prior to each DC vaccine (except DC vaccine #2) with Td pre-conditioning prior to vaccine #4.

This is a phase 1b, open-Label clinical trial to determine the safety and tolerability and to establish a preliminary recommended Phase 2 dose (RP2D) of TTAC-0001 administered in combination with pembrolizumab in patients with recurrent glioblastoma.
