18F-DOPA-PET/MRI Scan in Imaging Elderly Patients With Newly Diagnosed Grade IV Malignant Glioma or Glioblastoma During Planning for a Short Course of Proton Beam Radiation Therapy
This phase II trial studies how well fluorodopa F 18-positron emission tomography/magnetic resonance imaging scan (18F-DOPA-PET/MRI) works in imaging elderly patients with newly diagnosed grade IV malignant glioma or glioblastoma during planning for a short course of proton beam radiation therapy. 18F-DOPA is a chemical tracer that highlights certain cells during imaging. PET scan, is a metabolic imaging technique which takes advantage of how tumor cells take up nutrients differently than normal tissue. MRI scans are used to guide radiation therapy for most brain tumors. Hypofractionated proton beam therapy delivers higher doses of ...
[18F]Fluciclovine and [18F]FLT PET/CT Assessment of Primary High-Grade Brain Tumors
The hypothesis of this exploratory clinical trial in patients with high-grade a primary brain tumor who receive chemoradiation is that the PET imaging agents [18F]Fluciclovine and/or [18F]FLT will be a better predictor of tumor response than standard MRI based brain tumor response criteria. When used in conjunction, the two PET agents may be better able to predict tumor aggressiveness and thus overall survival than the use of individual-tracer PET biomarkers. This may eventually lead to improved assessment of response (including time to progression and overall survival) and differentiation of tumor recurrence/progression from ...
[18F]Fluciclovine in Post-treatment Glioblastoma ( Axumin )
Subjects with histologically proven glioblastoma (GBM) who are suspected to have progression and are candidates for a surgical resection according to standard of care may be eligible for this study. Subjects may participate in this study if they are at least 18 years of age. Positron emission tomography (PET/CT) imaging will be used to evaluate fluciclovine uptake at sites of suspected progression before planned surgery. In addition, clinical brain MRI with and without contrast will be used to evaluate the tumor pre-operatively. This is a non-therapeutic trial in that imaging will not be used to direct treatment decisions. ...
18F-Fluciclovine PET and Multiparametric MR Imaging
The purpose of the study is to investigate the use of the investigational agent Axumin (fluciclovine-F18) with PET/CT imaging in combination with standard MR imaging to detect remaining or recurrent brain tumor.
18F-fluciclovine PET/MRI Imaging for the Detection of Tumor Recurrence After Radiation Injury to the Brain
This phase I trial studies the ability and amount of fluciclovine positron emission tomography (PET) imaging needed to recognize tumors that have come back (recurrence) after brain injury from radiation therapy (radionecrosis) in patients with intracranial disease that has spread to other places in the body (metastatic). F-18 fluciclovine is a radiotracer that works by accumulating in tumor cells, making it easier to detect tumors. The results of this study may also help investigators understand all the ways that F-18 fluciclovine may affect patients.
18F-Fluorodopamine PET Studies of Neuroblastoma and Pheochromocytoma
PET (positron emission tomography) scans combined with a radioactive tracer will be used to identify and analyze tumors. Currently, the most common tracer used to analyze neuroblastoma tumors is called 123I-mIBG. However, the picture it provides is not always clear enough to see the very small areas of the disease. 18F-DA (18F-fluorodopamine) has been shown to be safe and more effective than 123I-mIBG in analyzing the tumor pheochromocytoma, which is closely related to neuroblastoma. With this research study, the investigators plan to meet the following goals: - Investigate to see if 18F-DA is safe to administer to pediatric...
18F-FMAU PET/CT and MRI for the Detection of Brain Tumors in Patients With Brain Cancer or Brain Metastases
This early phase I trial tests the use of a radioactive tracer (a drug that is visible during an imaging test) known as 18F-FMAU, for imaging with positron emission tomography/computed tomography (PET/CT) in patients with brain cancer or cancer that has spread to the brain (brain metastases). A PET/CT scan is an imaging test that uses a small amount of radioactive tracer (given through the vein) to take detailed pictures of areas inside the body where the tracer is taken up. 18F-FMAU may also help find the cancer and how far the disease has spread. Magnetic resonance imaging (MRI) is a type of imaging test used to diagnose brain ...
18F-MFBG Imaging for Evaluation of Neuroendocrine Malignancies
The purpose of this study is to see how a new tracer named 18F-MFBG (Meta Fluorobenzyl Guanidine) behaves in the body after injection, how it spreads to all the organs and how it is removed from the body. We will also study how long 18F-MFBG lasts in the blood after administered. In addition we want to study if 18F-MFBG can show Neuroendocrine tumors on a PET-CT or PET MR scan.
18F-MFBG PET Imaging of the Norepinephrine Transporter in Neural Crest and Neuroendocrine Tumors
The aim of this study is to evaluate the potential and feasibility of 18F-metafluorobenzylguanidine (18F-MFBG) positron emission tomography (PET) in patients with neural crest and neuroendocrine tumors.
19(T2)28z1xx Chimeric Antigen Receptor (CAR) T Cells in People With B-Cell Cancers
The purpose of this study is to test the safety of 19(T2)28z1xx CAR T cells in people with relapsed/refractory B-cell cancers. The researchers will try to find the highest dose of 19(T2)28z1xx CAR T cells that causes few or mild side effects in participants. Once they find this dose, they can test it in future participants to see if it is effective in treating their relapsed/refractory B-cell cell cancers. This study will also look at whether 19(T2)28z1xx CAR T cells work against participants' cancer.
