Filter by:The goal of this clinical research trial is to study the use of differing investigational doses and scheduling for Proton Therapy for tumors previously treated with radiation therapy. Generally, when patients are first treated for cancer with radiation therapy, they are treated with traditional photon (or x-ray) radiation therapy, which uses high-energy waves to kill tumor cells. In some cases, the cancer either returns or a new tumor can present in a different part of the body. With the usual radiation treatment, the photon beams travel all the way through the body. As a result, healthy tissues in front of and behind the tumor are exposed to radiation. Physicians who treat these cases where the tumor has returned often use a much lower dose of radiation to prevent patients from experiencing serious and long-term side-effects. This dose is often not strong enough to destroy the cancerous tumor. Alternatively, they may also treat a smaller area than would be indicated for complete tumor eradication, again in an attempt to prevent serious and long-term toxicities, but at the cost of optimally treating the cancer. Proton therapy, however, may offer a chance to safely deliver a more effective dose and volume of radiation as it is more targeted and can spare healthy tissues surrounding the tumor. The reason we are conducting this research study is to look at whether Proton therapy can be a better way to treat reoccurring tumors in patients who have previously received radiation therapy to the same area, compared to treatment approaches used to date.
The purpose of this study is to understand the breadth of molecular characteristics present in participants cared for in a large integrated, community-based health care system. Using comprehensive genomic profiling and proteomics, the investigators seek to identify the underlying genomic drivers of premalignant or malignant conditions in participants across different stages of disease development and cancer types. Comprehensive molecular profiling will consist of somatic tumor testing (tissue and/or blood) using whole exome sequencing, whole transcriptome sequencing, proteomics, and selected instances of whole genome sequencing. In addition, the investigators seek to perform broad hereditary cancer testing in affected participant populations. Hereditary testing has implications in screening, prognosis, and therapeutics for affected participants, as well as broad implications for genetic counseling and cascade testing. In order to maximize the value of genomic information, participants consented to this protocol will have their electronic health records (both retrospectively and prospectively) abstracted, curated, annotated and linked to genomic information obtained though the testing performed. Given the long-term value of this data, participants will also be asked to voluntarily consent to have their samples stored in a biobank and have their de-identified information used for future research. Information collected across this participant population will aid in advancing the investigators' knowledge of cancer biology, to discover and validate biomarkers associated with clinical outcomes, and shared in collaborative projects in order to promote the study of cancer.
This study is to collect and validate regulatory-grade real-world data (RWD) in oncology using the novel, Master Observational Trial construct. This data can be then used in real-world evidence (RWE) generation. It will also create reusable infrastructure to allow creation or affiliation with many additional RWD/RWE efforts both prospective and retrospective in nature.
SJELIOT is a phase 1 trial that aims to explore the combination of prexasertib with established DNA-damaging agents used in medulloblastoma to evaluate tolerance and pharmacokinetics in recurrent or refractory disease. Additionally, a small expansion cohort will be incorporated into the trial at the combination MTD/RP2D (maximum tolerated dose/recommended phase two dose) to detect a preliminary efficacy signal. Stratum A: Prexasertib and Cyclophosphamide Primary Objectives - To determine the safety and tolerability and estimate the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of combination treatment with prexasertib and cyclophosphamide in participants with recurrent/refractory Group 3 and Group 4 medulloblastoma and recurrent/refractory sonic hedgehog (SHH) medulloblastoma. - To characterize the pharmacokinetics of prexasertib in combination with cyclophosphamide. Secondary Objectives - To estimate the rate and duration of objective response and progression free survival (PFS) associated with prexasertib and cyclophosphamide treatment in this patient population. - To characterize the pharmacokinetics of cyclophosphamide and metabolites. Stratum B: Prexasertib and Gemcitabine Primary Objectives - To determine the safety and tolerability and estimate the MTD/RP2D of combination treatment with prexasertib and gemcitabine in participants with recurrent/refractory Group 3 and Group 4 medulloblastoma. - To characterize the pharmacokinetics of prexasertib in combination with gemcitabine. Secondary Objectives - To estimate the rate and duration of objective response and PFS associated with prexasertib and gemcitabine treatment in this patient population. - To characterize the pharmacokinetics of gemcitabine and gemcitabine triphosphate (only at St. Jude Children's Research Hospital).
The purpose of this study is to use an imaging method called functional magnetic resonance imaging (fMRI) in patients who have a tumor near an area of the brain that is believed to control language. The fMRI is a new kind of imaging that uses a strong magnetic field to look at functioning brain tissue. This kind of imaging will be used to study the effect of the brain tumor on your speech.
This research protocol makes pictures of brain tumors. The pictures are made with a positron emission tomography (PET) scanner. PET scans use radioactivity to "see" cancer cells. We are using a new kind of PET scan. The new PET scan is called [18F]-FACBC PET. We will compare this to the standard PET scan. The standard PET scan is called [11C]-methionine PET. We expect these pictures will give us information about your tumor. We also hope to collect information about the amount of radioactivity exposure. We will measure radioactivity exposure to your tumor, brain and other organs. The research study results will be used to support the submission of an investigational new drug (IND) application to the Food and Drug Administration (FDA).
A significant number of brain tumor patients who received radiation or chemotherapy have thinking problems as a result of their treatment. The purpose of this study is to find out if treatment with Aricept (donepezil) may improve some aspects of thinking abilities in patients with brain tumors who received radiation or chemotherapy. This research will also study whether persons having particular genes for a blood-borne substance called apolipoprotein E (APOE) are more likely to have thinking problems after radiation or chemotherapy treatment for their brain tumors. The findings of this study will help us find out whether Aricept can improve thinking abilities after cancer treatment, and whether some of the thinking difficulties may be in part related to having certain genes.
The purpose of this study is to find out what effects, good and/or bad, sunitinib has on patients and their tumors. At this time, no drugs are routinely used to treat meningioma, hemangioblastoma or hemangiopericytoma. Only surgery and radiation therapy are known to be useful. Sunitinib is a drug approved for advanced kidney cancer. Sunitinib is also being studied for other tumors. It may be useful in the treatment of brain tumors because it can prevent formation of new blood vessels that allow tumor cells to survive and grow.
The purpose of this study is to determine the safest dose of d-methadone that can be given, without causing severe side effects in most patients with chronic pain. Patients are being asked to participate in the Phase I portion of this study.
The purpose of this study is to see how effective treatment of high doses of chemotherapy is for your tumor. We will also be looking at the side effects and risks of this treatment. You will receive very high doses of chemotherapy. High doses of chemotherapy can destroy tumor cells, but it can also destroy normal bone marrow cells. These cells produce white blood cells (which fight infection), red blood cells (which carry oxygen) and platelets (which allow your blood to clot). With too few of these cells there is a serious risk of infection and bleeding. Therefore, before treatment begins, we will collect some of your own blood cells, called peripheral blood progenitor cells (PBPCs). These cells help create new blood cells. The PBPCs are frozen and saved while you are being treated. Then at the end of treatment, your PBPCs are thawed and given back to you. These healthy PBPCs will replace the blood cells that the high dose chemotherapy destroys and allow your bone marrow to recover and produce blood cells. In a prior study we treated 69 patients in a similar way. More than half were able to avoid or delay brain radiation. This new study will use a different high dose chemotherapy regimen.
