SUV on 68Ga-DOTATATE PET/CT and Ki-67 Index in Neuro-Endocrine Tumors
Positron emission tomography/computed tomography (PET/CT) is an advanced nuclear medicine scan. This technology allows precise and early cancer to be visualized and measured on whole body images. Patients with Neuro-Endocrine tumors (NETs), require specialized molecular imaging to stage, re-stage and assess eligibility and response to therapy. 68Ga-DOTATATE is a nuclear medicine imaging agent that is not yet approved by Health Canada but used extensively throughout the world. The Ki-67 index, a marker of cell proliferation in NETs, is one of the most important prognostic factors in this disease. The objective of this study is to evaluate ...

The Efficacy and Safety of Beta-blockers Drugs in Adults With Spinal Hemangioma
Spinal hemangioma is one of the most common benign vertebral tumours. Being mostly asymptomatic, it is still associated with a pain syndrome especially if encroaches into the neural canal. This study is organised to evaluate the efficacy and safety of β-blockers drugs in adults with spinal hemangioma.

The Impact of Resistance ExerciSe on Muscle Mass in GlioblaSToma Survivors
Glioblastoma patients are confronted with a debilitating disease associated with a low survival rate and poor quality of life. The goal of this study will be to reach a largely underrepresented population in the exercise literature and explore the role of a tailored circuit-based resistance training program on functional fitness (i.e., ability to carry out tasks of daily living) and associated health outcomes (e.g., quality of life) for GBM patients on active treatment.

The Neural Coding of Speech Across Human Languages
The overall goal of this study is to reveal the fundamental neural mechanisms that underlie comprehension across human spoken languages. An understanding of how speech is coded in the brain has significant implications for the development of new diagnostic and rehabilitative strategies for language disorders (e.g. aphasia, dyslexia, autism, et alia). The basic mechanisms underlying comprehension of spoken language are unknown. Researchers are only beginning to understand how the human brain extracts the most fundamental linguistic elements (consonants and vowels) from a complex and highly variable acoustic signal. Traditional ...

Understanding Immunotherapy Resistance Mechanisms in Advanced Melanoma
Purpose of the study: The investigators are proposing that melanomas which respond and develop eventual disease stability in response to checkpoint inhibitor immunotherapy undergo a genetic program promoting secondary resistance.

Vestibular Precision: Physiology & Pathophysiology
This project will investigate the role of noise in the vestibular system, and in particular its effects on the variability (precision) of vestibular-mediated behaviors. The investigators will study vestibular precision in normal subjects and patients with peripheral vestibular damage, and will investigate its potential plasticity. The goals are to develop a better understanding of the role noise plays in the vestibular system in normal and pathologic populations, and to determine if the brain can learn to improve signal recognition within its inherently noisy neural environment, which would result in improved behavioral precision.

131-I-MIBG Therapy for Refractory Neuroblastoma, Expanded Access Protocol
Metaiodobenzylguanidine (MIBG) is a substance that is taken up by neuroblastoma 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 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. A recent New Approaches to Neuroblastoma Therapy (NANT) phase 2 randomized trial of 131I-MIBG with or without...

131I-omburtamab for the Treatment of Central Nervous System/Leptomeningeal Neoplasms in Children and Young Adults
The researchers are doing this study to provide access to treatment with 131I-omburtamab for children and young adults who have CNS/leptomeningeal neoplasms. 131I-omburtamab is an investigational drug; the FDA has not approved it to treat this cancer or any other disease. However, the agency has granted the drug Breakthrough Therapy Designation for the treatment of neuroblastoma with CNS metastases.

A Cohort IND Expanded Access Program for Supporting Patient Access to Tebentafusp
This Expanded Access Program aims to: 1. Provide access to tebentafusp for mUM patients. 2. Provide access to tebentafusp for patients, who were on the control arm of the randomized controlled Phase II trial (IMCgp100-202) and were unable to crossover during the specified window. 3. Ensure that patients, who are benefiting from tebentafusp treatment while participating in an ongoing Immunocore sponsored clinical study (e.g., IMCgp100-102 or IMCgp100-201), may continue tebentafusp treatment on this Programme once the ongoing trial has met all of its key primary and secondary objectives.
