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 ...
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.
This study will examine whether positron emission tomography (PET) imaging with fluciclovine can reliably differentiate true progression from pseudoprogression months earlier than the conventional MRI methods.
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.
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...
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 ...
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.
The aim of this study is to evaluate the diagnostic performance and tumor burden of 18F-metafluorobenzylguanidine (18F-MFBG) positron emission tomography (PET) in patients with neuroendocrine tumors mainly in pheochromocytoma and paraganglioma (PPGL) and neuroblastoma (NB).
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.
The proposed Phase IIB/III randomized, double-blind, placebo-controlled trial in subjects with newly diagnosed primary glioblastoma multiforme (ndGBM) aims to compare the efficacy and safety of 2-OHOA versus placebo, given with standard of care (SoC) therapy of radiation therapy plus temozolomide (TMZ), followed by an adjuvant treatment of 6 month period of TMZ and then 2-OHOA or placebo in monotherapy.
