Dopamine Agonist Treatment of Non-functioning Pituitary Adenomas
Due to lack of hormone overproduction in non-functioning pituitary adenomas (NFPAs), only the symptomatic adenomas or large adenomas with proven growth and risk for symptoms in near future will undergo pituitary surgery. The remaining adenomas are monitored regularly. Operation of these large adenomas will rarely remove all tumour tissue, and there is also a risk of worsening of pituitary function. Often, adenomas with the highest growth potential are operated several times and some also need radiation therapy, providing additional risk for pituitary failure. Unlike some of the hormone-producing adenomas, there is no established pharmacological treatment for NFPAs. However, there...

Dose-Escalated Photon IMRT or Proton Beam Radiation Therapy Versus Standard-Dose Radiation Therapy and Temozolomide in Treating Patients With Newly Diagnosed Glioblastoma
This randomized phase II trial studies how well dose-escalated photon intensity-modulated radiation therapy (IMRT) or proton beam radiation therapy works compared with standard-dose radiation therapy when given with temozolomide in patients with newly diagnosed glioblastoma. Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs, such as temozolomide, may make tumor cells more sensitive to radiation therapy. It is not yet known whether dose-escalated photon IMRT or...

Dose Escalation Study of a PD1-LAG3 Bispecific Antibody in Patients With Advanced and/or Metastatic Solid Tumors
This is a first-in-human, open-label, multicenter, Phase I multiple-ascending dose (MAD) study of RO7247669, an anti PD-1 (programmed death-1) and LAG-3 (Lymphocyte-activation gene 3) bispecific antibody, for participants with advanced and/or metastatic solid tumors. This study aims to establish the maximum tolerated dose (MTD) and/or define the recommended phase 2 dose (RP2D) based on the safety, tolerability, pharmacokinetic (PK) and/or pharmacodynamic (PD) profile of RO7247669, and to evaluate preliminary anti-tumor activity in participants with solid tumors. An expansion part of the study is planned to enroll tumor-specific cohorts to evaluate anti-tumor activity of the MTD...

Dose Escalation Study of CLR 131 in Children, Adolescents, and Young Adults With Relapsed or Refractory Malignant Tumors Including But Not Limited to Neuroblastoma, Rhabdomyosarcoma, Ewings Sarcoma, and Osteosarcoma
The study evaluates CLR 131 in children, adolescents, and young adults with relapsed or refractory malignant solid tumors and lymphoma and recurrent or refractory malignant brain tumors for which there are no standard treatment options with curative potential.

Dose Escalation Trial of Neoadjuvant Radiosurgery for the Treatment of Metastatic Brain Tumors
The purpose of this study is to study if giving radiation to a brain tumor (a procedure called radiosurgery) before neurosurgery (surgery to remove the tumor) will help to keep brain tissue healthy, while possibly eliminating the need to return for radiation once a patient has healed from neurosurgery. This study will also seek the best radiation dose on a brain tumor based on how well the radiation therapy works and asses the side-effects.

DOTATOC 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 68Gallium(68Ga)-DOTATOC positron emission tomography/computed tomography (PET/CT) is superior to current imaging techniques. The goal is to evaluate the safety and sensitivity of 68Ga-DOTATOC PET/CT at detecting NETs and other tumors with over-expression of somatostatin receptors.

DSC-MRI in Measuring rCBV for Early Response to Bevacizumab in Patients With Recurrent Glioblastoma
This phase II trial studies how well dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSC-MRI) works in measuring relative cerebral blood volume (rCBV) for early response to bevacizumab in patients with glioblastoma that has come back. DSC-MRI may help evaluate changes in the blood vessels within the cancer to determine a patient?s response to treatment.

Dual Tracer (68Ga-DOTATATE and 18F-FDG) PET Imaging in G2 & G3 Gastroenteropancreatic Neuroendocrine Tumors
The variable clinical outcome of patients with G2 & G3 well diff GEP-NETs makes the selection of an optimal treatment strategy challenging. Initial data suggests that high DOTATATE uptake and low FDG uptake are suggestive of low grade disease, with an indolent course. Conversely, low DT uptake and high FDG uptake are suggestive of high-grade/ aggressive disease. G2/3 GEP NETs may be biologically diverse; clinically relevant cohort for dual-tracer PET imaging. Our secondary objectives are 1. To determine the distribution of PETNET scores derived from 18F-FDG & 68Ga-DT PET in patients with G2 & G3 well diff GEP-NETs. 2. To determine the proportion of patients...
