Photodynamic Therapy (PDT) for Recurrent Pediatric Brain Tumors

Brain TumorRecurrent

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.

Safety and Imaging Study of GC1008 in Glioma

Primary Brain Tumors

Brain tumors account for only 2% of all cancers but result in a disproportionate share of cancer morbidity and mortality. The five-year survival rates for the most common histologic subtypes, anaplastic astrocytoma and glioblastoma (glioblastoma multiforme, GBM), are 30% and 10%, respectively. Drugs affecting transforming growth factor-β (TGF-β) might be of great interest for malignant glioma treatment. TGF-β is an oncogenic factor in advanced tumors where it induces proliferation, angiogenesis, invasion, and metastasis as well as suppresses the antitumoral immune response. In addition TGF-β and its TGF-β receptors, TβRI and TβRII, are overexpressed in GBMs. TGF-β signaling is involved in multiple steps of GBM development. GC1008 is an antibody that is capable of neutralizing TGF-β and may therefore offer a new treatment option for patients with malignant glioma. For therapeutic success, it may be essential for GC1008 to reach the target site, in this case located in the brain. We will be able to prove this with 89Zr-GC1008 PET imaging. This imaging method also allows quantification of the amount of GC1008 reaching the tumor. This study consists of 2 parts. In part 1, patients with a suspicion of a malignant glioma undergo an 89Zr-GC1008 PET scan before standard (surgical)treatment. In part 2, patients with relapsed malignant glioma will undergo an 89Zr-GC1008 PET scan and will be treated with GC1008 in a phase II study as there is no standard treatment for these patients. We hypothesize that GC1008 uptake in brain tumors can be visualized and quantified using the 89Zr-GC1008 PET scan and GC1008 might offer a new treatment option for patients with relapsed malignant gliomas.

Glioblastoma Multiforme (GBM) Proton vs. Intensity Modulated Radiotherapy (IMRT)

Brain Cancer

The goal of this clinical research study is to compare IMRT with IMPT in patients with glioblastoma. Researchers want to learn about cognitive side effects (mental status changes) that may occur, such as memory loss and impaired thinking. IMRT is the delivery of focused radiation therapy using photon beams and advanced computer planning to help shape the dose in order to give the highest possible dose to the tumor with the least dose to surrounding normal tissues. IMPT is also focused radiation therapy similar to IMRT, but it uses proton particles to deliver the radiation instead of photon beams. IMPT also uses advanced computer planning in order to shape the dose to the target with the least dose to surrounding normal tissues.

Carboplatin and Bevacizumab for Progressive Breast Cancer Brain Metastases

Metastatic Breast CancerBreast Cancer1 more

The purpose of this research study is to determine how well the combination of bevacizumab and carboplatin works in treating breast cancer that has spread to the brain. Bevacizumab is an antibody (a protein that attacks a foreign substance in the body) that is made in the laboratory. Bevacizumab works differently from the way chemotherapy drugs work. Usually chemotherapy drugs attack fast growing cancer cells in the body. Bevacizumab works to slow or stop the growth of cells in cancer tumors by decreasing the blood supply to the tumors. When the blood supply is decreased, the tumors don't get the oxygen and nutrients they need to grow. Carboplatin is in a class of drugs known as platinum-containing compounds and has been approved for use in the treatment of ovarian cancer. Information from other research studies suggests that the combination of bevacizumab with carboplatin may be effective in treating breast cancer.

A Study of the Specificity and Sensitivity of 5- Aminolevulinic Acid (ALA) Fluorescence in Malignant...

Brain Neoplasms

Extent of resection is a very important prognostic factor affecting survival in individuals diagnosed with a malignant glioma. However, the infiltrative nature of the malignant glioma tumor cells produces indistinct borders between normal and malignant tissues, and the lack of easily identifiable tumor margins confounds attempts at total resection. The investigators propose to identify the borders of malignant gliomas intraoperatively using oral 5-aminolevulinic Acid (5-ALA) which results in fluorescence of the malignant cells and thereby provide an opportunity for more complete tumor resection. When exogenous 5-ALA is provided at increased concentration the tumor cells will become fluorescent under ultraviolet light. This feature identifies the tumor cells intraoperatively and facilitates complete resection. Data collection will include measurement of dose-limiting toxicity, tumor fluorescence, and tumor density. Data analysis will evaluate toxicity, sensitivity, and specificity of 5-ALA. Time-to-progression, one year survival rate and total survival will be measured as a function of the extent of resection. (Details below in Detailed Description.) Following completion of the phase 1 portion of this trial, an additional 15 subjects will be entered at the recommended phase 2 dose level in order to further define the above parameters at the recommended phase 2 dose level.

131I-L19SIP Radioimmunotherapy (RIT) in Combination With External Beam Radiation in Patients With...

Brain Metastases From Solid Tumors

The aim of this Proof of Concept study is to determine the therapeutic potential of the L19SIP antibody, labeled with the radionuclide 131I in combination with external beam radiation, for the treatment of patients with multiple brain metastases following the promising results with this agent in previous clinical studies. The L19SIP antibody is a fully human antibody, capable of preferential localization around tumor blood vessels while sparing normal tissues. The formation of new blood vessels is a rare event in the adult (exception made for the female reproductive cycle), but is a pathological feature in most aggressive types of cancer. The presented study follows a Phase I and a subsequent Phase I/II dose finding and efficacy study with the same agent in patients with a variety of cancers where 131I-L19SIP had shown an excellent tolerability and therapeutic benefit for some patients enrolled in the study.
