11 Clinical Trials for Various Conditions
This study is a clinical trial to determine the safety of inoculating G207 (an experimental virus therapy) into a recurrent or refractory cerebellar brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication, tumor cell killing, and an anti-tumor immune response, will also be tested.

Approximately 90% of children with malignant brain tumors that have recurred or relapsed after receiving conventional therapy will die of disease. Despite this terrible and frustrating outcome, continued treatment of this population remains fundamental to improving cure rates. Studying this relapsed population will help unearth clues to why conventional therapy fails and how cancers continue to resist modern advances. Moreover, improvements in the treatment of this relapsed population will lead to improvements in upfront therapy and reduce the chance of relapse for all. Novel therapy and, more importantly, novel approaches are sorely needed. This trial proposes a new approach that evaluates rational combination therapies of novel agents based on tumor type and molecular characteristics of these diseases. The investigators hypothesize that the use of two predictably active drugs (a doublet) will increase the chance of clinical efficacy. The purpose of this trial is to perform a limited dose escalation study of multiple doublets to evaluate the safety and tolerability of these combinations followed by a small expansion cohort to detect preliminary efficacy. In addition, a more extensive and robust molecular analysis of all the participant samples will be performed as part of the trial such that we can refine the molecular classification and better inform on potential response to therapy. In this manner the tolerability of combinations can be evaluated on a small but relevant population and the chance of detecting antitumor activity is potentially increased. Furthermore, the goal of the complementary molecular characterization will be to eventually match the therapy with better predictive biomarkers. PRIMARY OBJECTIVES: * To determine the safety and tolerability and estimate the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of combination treatment by stratum. * To characterize the pharmacokinetics of combination treatment by stratum. SECONDARY OBJECTIVE: * To estimate the rate and duration of objective response and progression free survival (PFS) by stratum.
Glioblastoma (GBM) and gliosarcoma (GS) are the most common and aggressive forms of malignant brain tumor in adults and can be resistant to conventional therapies. The purpose of this Phase II study is to evaluate how well a recurrent glioblastoma or gliosarcoma tumor responds to one injection of DNX-2401, a genetically modified oncolytic adenovirus, when delivered directly into the tumor followed by the administration of intravenous pembrolizumab (an immune checkpoint inhibitor) given every 3 weeks for up to 2 years or until disease progression.

Glioblastoma (GBM) and gliosarcoma (GS) are the most common and aggressive forms of malignant primary brain tumor in adults and can be resistant to conventional therapies. The purpose of this Phase Ib study is to evaluate how well a recurrent glioblastoma or gliosarcoma tumor responds to one injection of DNX-2401, a genetically modified, conditionally replicative and oncolytic human-derived adenovirus. DNX-2401 is delivered directly into the tumor where it may establish an active infection by replicating in and killing tumor cells.
There is currently no standard treatment for patients with neuro-epithelial (brain) or other solid tumors in another part of the body who do not have adequate suitable autologous hematopoietic progenitor cells available and/or whose disease has relapsed after standard treatment. Allogeneic Hematopoietic Progenitor Cell Transplant may be a consideration for treatment of patients with recurrent chemo-responsive malignant (high grade) neuro-epithelial and other solid tumors or those who do not have suitable autologous hematopoietic progenitor cell availability. The procedure in which your own blood stem cells are transplanted to you is called an autologous (from your own) progenitor cell transplant and when cells from a matched donor are transfused is called an allogeneic progenitor cell transplant. The study is being conducted to evaluate the safety and effectiveness of a combination of drugs followed by an allogeneic hematopoietic progenitor cell transplant (HPCT). This treatment regimen is experimental in that although the individual drugs are commonly used to treat your disease, the specific combination used in this protocol followed by the transplant is experimental.
The purpose of this study is to test the feasibility (ability to be done) of experimental technologies to determine a tumor's molecular makeup. This technology includes a genomic report based on DNA exomes and RNA sequencing that will be used to discover new ways to understand cancers and potentially predict the best treatments for patients with cancer in the future.
This is an open-label, multi-center, Phase 1/2 study of the brain-penetrant MEK inhibitor, mirdametinib (PD-0325901), in patients with pediatric low-grade glioma (pLGG).
This study will be aimed at investigating the effectiveness of a treatment for brain tumors called Photodynamic Therapy, or PDT. Briefly, a subject will receive a light-sensitive drug, called Photofrin®, the day before a tumor removal surgery. The next day, after the tumor is removed, red light from a laser will be shone into the tumor cavity through a light-diffusing sphere. This light will activate the photosensitizer, and possibly kill any tumor cells that may be left. We plan to measure how long the subject may go without a new tumor regrowth, and overall how long subjects survive. We will compare these results to typical results to see if we are seeing any improvements. Objective: To define the antitumor activity of Photofrin® and laser light activation within the confines of a Phase II study.
The goal of this proposal is to evaluate a new Photodynamic Therapy (PDT) modification which could revolutionize the treatment of brain tumors in children and adults. There are currently few cases published involving the use of PDT in infratentorial (in the posterior fossa) brain tumors in general and specifically those occurring in children. The investigators propose to test a technique, for the first time in the U.S., that demonstrated in Australian adult glioblastoma patients dramatic long-term, survival rates of 57% (anaplastic astrocytoma) and 37% (glioblastoma multiforme). These results are unprecedented in any other treatment protocol. Photodynamic therapy (PDT) is a paradigm shift in the treatment of tumors from the traditional resection and systemic chemotherapy methods. The principle behind photodynamic therapy is light-mediated activation of a photosensitizer that is selectively accumulated in the target tissue, causing tumor cell destruction through singlet oxygen production. Therefore, the photosensitizer is considered to be the first critical element in PDT procedures, and the activation procedure is the second step. The methodology used in this proposal utilizes more intensive laser light and larger Photofrin photosensitizer doses than prior PDT protocols in the U.S. for brain tumor patients. The PDT will consist of photoillumination at 630 nm beginning at the center of the tumor resection cavity, and delivering a total energy of 240 J cm-2. The investigators feel that the light should penetrate far enough into the tissue to reach migrating tumor cells, and destroy these cells without harming the healthy cells in which they are dispersed. The investigators will be testing the hypothesis that pediatric subjects with progressive/recurrent malignant brain tumors undergoing PDT with increased doses of Photofrin® and light energy than were used in our previous clinical study will show better progression free survival (PFS) and overall survival (OS) outcomes. PDT will also be effective against infratentorial tumors. The specific aims include determining the maximum tolerable dose (MTD) of Photofrin in children and looking for preliminary effectiveness trends.
The primary objective of this study is to evaluate the safety, efficacy and clinical activity of Pamiparib in combination with radiation therapy (RT) and/or temozolomide (TMZ) in participants with newly diagnosed or recurrent/refractory glioblastoma.
This multicenter, Phase 1b/2 study is being conducted to determine if the experimental cell therapy is safe, tolerable and can delay the return of cancer in patients with a newly diagnosed or recurrent glioblastoma multiforme (GBM) in combination with standard chemotherapy treatment temozolomide (TMZ). If there is a 25% or greater improvement in survival in this study then the therapy should be studied further.
