Although many intratympanic agents have been attempted, N-Acetylcysteine (NAC) appears to be the most promising and is a powerful, commonly used anti-oxidant. The goal of this prospective phase 2 randomized controlled trial is to determine the optimal dosage and effectiveness of intratympanic NAC injection in reducing hearing loss in head & neck cancer patients receiving cisplatin chemotherapy with curative intent.
This phase I/Ib trial studies the side effects and best dose of intrathecal nivolumab, and how well it works in combination with intravenous nivolumab in treating patients with leptomeningeal disease. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
This study will investigate the tumor-associated vasculature of patients with solid tumors. The investigators will use a technology known as intravital microscopy (IVM) in order to visualize in real-time the vessels associated with solid tumors. The IVM observations may determine if an individual patient's tumor vessels would be amenable to receiving systemic therapy, based on the functionality of the vessels.
The MyBrain study investigates the brain function of children, adolescents and young adults during and after chemo treatment for cancer. The tests include 1) cognitive skills such as memory and attention; 2) the brain's electrical activity; 3) and biological markers related to brain function. The aim of the study is to better understand the trajectories of cognitive functioning and measures that have been associated with cognitive impairment in patients treated with chemotherapy.
A medication called temozolomide has been used for many years in the treatment of high-grade gliomas, which are tumours that originate in the brain. While this drug is the normal treatment for high-grade glioma, a number of patients develop a side-effect which results in low levels of some important blood cells, such as platelets or white blood cells. If this side-effect occurs, treatment with temozolomide may have to be stopped or paused, which may affect how well this treatment works. At present, it is unknown why some patients develop this side effect and others do not. It is known that patients with a higher concentration of temozolomide in their blood are at an increased...
The overall objective of this research is to investigate the clinical characteristics pre- and post-brain tumour resection with a focus on visual verticality disorder, and lateropulsion, including neuroimaging analysis, of a neurosurgical cohort of patients with brain tumours. This prospective observational cohort study will investigate clinical and neuroimaging characteristics and the relationship between lateropulsion and visual verticality disorder in patients pre- and post-brain tumour resection. Patients (aged 18-80 years, with a confirmed diagnosis of brain tumour and a neurosurgical pathway) will be enrolled from the state-wide Neurosurgery Service of Western Australia at...
This study is designed as a single center, prospective, open label, single-arm therapeutic trial with both surgical and non-surgical cohorts.
The purpose of this study is to explore whether chemotherapy and targeted-therapy regimens guided by organoid drug sensitivity test can improve the outcomes of non-resectable locally advanced and metastatic Pancreatic neuroendocrine tumors. At the same time, this study will evaluate the successful stablishment rate of organoid from biopsy tissue , and explore the concordance between drug sensitivity test results and patients' treatment response
The Cytophone is a first in the world patented system to identify and count single circulating melanoma cells in blood circulation inside the human body. The Cytophone has a unique capability to find rare melanoma cells in the blood by an assessment of 100-500 times greater amounts of blood volume than routine blood tests. The important benefit of the Cytophone diagnosis is that the test does not require injection or any skin incision (i.e., non-invasiveness). The goal of this clinical trial is to demonstrate evidence of the capability of the Cytophone test to indicate a risk of metastasis and define CTC counts that correlate with melanoma recurrence, progression of metastatic...
This study will enroll up to 30 evaluable patients with pheochromocytoma or paraganglioma who are undergoing surgical or systemic treatment. A pre-treatment 18F-FluorThanatrace ([18F]FTT) positron emission tomography/computed tomography (PET/CT) scan will be done prior to surgery or systemic therapy. PET/CT imaging will be used to evaluate PARP-1 expression in sites of pheochromocytoma or paraganglioma using the investigational radiotracer [18F]FTT. This is an observational study in that [18F]FTT PET/CT will not be used to direct treatment decisions. While patients and referring physicians will not be blinded to the [18F]FTT PET/CT results, treatment decisions will be made by...
