CB-839 With Radiation Therapy and Temozolomide in Treating Participants With IDH-Mutated Diffuse Astrocytoma or Anaplastic Astrocytoma

This phase 1b trial studies the side effects and best dose of glutaminase inhibitor CB-839 hydrochloride (CB-839) in combination with radiation therapy and temozolomide in treating participants with IDH-mutated diffuse or anaplastic astrocytoma. CB-839 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or stopping them from spreading. Giving CB-839 with radiation therapy and temozolomide may work better in treating participants with IDH-mutated diffuse astrocytoma or anaplastic astrocytoma.

A Study of Therapeutic Iobenguane (131-I) for Relapsed, High-Risk Neuroblastoma Subjects (OPTIMUM)

The purpose of this study is to evaluate the efficacy and safety of 131I-MIBG in patients with neuroblastoma, who relapsed.

Theranostics: 68GaDOTATOC and 90YDOTATOC (PRRT)

Participants in this research study have tumors that express somatostatin receptors such as a neuroendocrine tumor, medulloblastoma, meningioma, and neuroblastoma.

The purpose of this research study is to determine if 90Y-DOTATOC is an effective treatment for tumors that express somatostatin receptors and if 68Ga-DOTATOC PET/CT can measure the extent of disease and measure response to this therapy. This research will determine if this process called dosimetry is an effective technique to determine how much 90Y-DOTATOC the participants can safely receive without damage to their kidneys and bone marrow.

Safety of 68Ga-DOTA-tyr3-Octreotide PET in Diagnosis of Solid Tumors (GA-68)

This protocol is designed to test the efficacy of 68Ga-DOTATOC PET/CT in diagnosis, staging, and measurement of response to treatment in patients with somatostatin receptor positive tumors. Goals are to 1) compare this unique PET/CT scan with the current standard of care which is a combination of Octreoscan SPECT (single photon emission tomography) plus a high resolution, contrast enhanced CT; 2) Determine the sensitivity of 68Ga-DOTATOC PET/CT in diagnosis of patients with suspected somatostatin receptor positive tumor; and 3) For those patients who have had recent treatment (e.g., surgery, chemotherapy, targeted therapy such as anti-angiogenics, kinase inhibitors, peptide receptor radiotherapy), this scan will be used to measure response to treatment. These studies will be obtained with the long term goal of submitting a New Drug Application (NDA) for FDA approval of 68Ga-DOTATOC PET/CT in adults and children.
