[11C]Acetate PET in Patients With Glioma
At each point that the patient will have [11C]-Acetate PET study, this will be compared with standard clinical MR imaging. Abbreviations: XRT - radiation therapy; TMZ - temozolomide (chemotherapy) Quantitative Image Data Analysis: The [11C]-Acetate uptake in tumor sites from images will be analyzed qualitatively by visual assessment, quantitatively using a standard uptake value (SUV) in the tumor relative to the contralateral normal brain, and the parameters obtained by compartmental modeling of dynamic data.
131I-IPA + XRT as Treatment for Patients With Glioblastoma Multiforme
A multi-centre, open-label, single-arm, dose-finding phase I/II study to evaluate safety, tolerability, dosing schedule, and preliminary efficacy of carrier-added 4-L-[131I]iodo-phenylalanine (131I-IPA), administered as single or repetitive injections in patients with recurrent glioblastoma multiforme (GBM), concomitantly to 2nd line external radiation therapy (XRT) - IPAX-1
131I-Labeled MIBG for Refractory Neuroblastoma: A Compassionate Use Protocol
This is a compassionate use protocol to allow patients with advanced neuroblastoma palliative access to 131I-metaiodobenzylguanidine (131I-MIBG).
131-I-MIBG Therapy for Refractory Neuroblastoma and Metastatic Paraganglioma/Pheochromocytoma
Metaiodobenzylguanidine (MIBG) is a substance that is taken up by neuroblastoma or pheochromocytoma/paraganglioma tumor cells. MIBG is combined with radioactive iodine (131 I) in the laboratory to form a radioactive compound 131 I-MIBG. This radioactive compound delivers radiation specifically to the cancer cells and causes them to die. The purpose of this research protocol is to provides a mechanism to deliver MIBG therapy when clinically indicated, but also to provide a mechanism to continue to collect efficacy and toxicity data that will be provided.
131I-omburtamab Radioimmunotherapy for Neuroblastoma Central Nervous System/Leptomeningeal Metastases
Children with a neuroblastoma diagnose and central nervous system (CNS)/leptomeningeal metastases will be given up to 2 rounds of intracerebroventricular treatment with a radiolabelled monoclonal antibody, 131I-omburtamab to evaluate efficacy and safety
177Lu-DOTA-TATE and Olaparib in Somatostatin Receptor Positive Tumours
This is a phase I study of 177Lu-DOTA-TATE in combination with the PARP-inhibitor olaparib for treatment of patients with somatostatin receptor positive tumours detected by 68Ga-DOTA-TATE/TOC PET. The combination of a PARP inhibitor that will specifically target the repair mechanism, with ionising radiation causing SSB's might overcome the repair dependent survival of the tumour cells, making them more sensitive to β-emission and increase the probability of tumour cell death.
177Lu-DTPA-Omburtamab Radioimmunotherapy for Leptomeningeal Metastasis From Solid Tumors
Adults with leptomeningeal metastasis from solid tumors will be treated with 177Lu-DTPA-omburtamab, which is a radioactive labelling of a murine monoclonal antibody targeting B7-H3.
177Lu-DTPA-Omburtamab Radioimmunotherapy for Recurrent or Refractory Medulloblastoma
Children and adolescents diagnosed with medullablastoma and with recurrent or refractory to frontline therapy will be treated with 177Lu-DTPA-omburtamab, which is a radioactive labelling of a murine monoclonal antibody targeting B7-H3.
177Lutetium-octreotate Treatment Prediction Using Multimodality Imaging in Refractory NETs
The purpose of this study is to determine if 68Gallium-octreotate and 18Fluorodesoxyglucose uptake, apparent diffusion coefficient and post 177Lu-octreotate SPECT/CT dosimetry are reliable predictors for lesion-by-lesion treatment outcome.
18F-AmBF3-TATE PET/CT for Imaging NET Patients
Neuroendocrine tumours (NETs) are generally slow growing, but some can be aggressive and resistant to treatment. Compared to healthy cells, the surface of these tumor cells has a greater number of special molecules called somatostatin receptors (SSTR). Somatostatin receptor scintigraphy and conventional imaging are used to detect NETs. This study proposes 18F-AmBF3-TATE positron emission tomography/computed tomography (PET/CT) is superior to current imaging techniques. The goal is to evaluate the biodistribution and safety of 18F-AmBF3-TATE PET/CT for neuroendocrine tumour imaging.
