Clinical Trials
UCLA Radiological Sciences is engaged in investigating new approaches to diagnosing and treating diseases and conditions.
The clinical trials are done in close collaboration with scientists and physicians from many areas of expertise. All trials are overseen by the Institutional Review Board (IRB) to ensure the highest ethical standards.
The following lists the clinical trials that are currently recruiting participants:
NOLA (NeuWave Observational Liver Ablation) Registry
This is a multicenter, observational registry that follows patients for a total of 5 years from the date of the first liver ablation procedure with the NEUWAVE Microwave Ablation System. The data gathered from participating sites will be available to be analyzed to develop ablation parameter guidance for ablation approaches under varying patient liver tissue conditions and liver lesions.
This is an "umbrella registry," which was included as an optional component in other NEUWAVE studies; hence, data from consenting patients who are or will be enrolled in other NEUWAVE soft tissue liver lesion ablation studies will be included in this registry. All other patients will be enrolled and followed prospectively, enrolled retrospectively with prospective, longitudinal follow up, or enrolled retrospectively with all retrospective follow up.
Enrollment for this study will include up to 1,500 patients throughout the world who underwent or are scheduled to undergo microwave ablation of one or more soft tissue liver lesions using the NEUWAVE Microwave Ablation System or the NEUWAVE Microwave Ablation System with Ablation Confirmation.

Genicular Artery Embolization Vs Observation for Symptomatic Knee Osteoarthritis (GRAVITY)
The purpose of this clinical trial is to determine whether genicular artery embolization (GAE) is an effective way to treat knee pain from osteoarthritis. Pain from arthritis is often due to underlying inflammation in the joint. The inflammation is associated with increased abnormal blood flow going to the specific area of pain. If the investigator can reduce the blood flow, the inflammation can be reduced and the pain can be controlled.
The GAE procedure is an experimental procedure to decrease the blood flow (embolize) to the specific region of the knee that is causing the pain. This will be done by infusing microscopic spheres into the specific blood vessel (genicular artery) supplying the area of pain in the knee. This is done through a procedure which is called an angiogram, which is done entirely through a pinhole at the creased of the thigh, using twilight (conscious) sedation.
The investigators have already completed an initial trial at UCLA, and shown that this procedure is safe and effective. The purpose of this new trial is to compare outcomes of people undergoing the GAE procedure to those who do not undergo the procedure. A total of 100 patients will be enrolled, and 2/3 of the patients will be randomly selected to undergo the GAE procedure. 1/3 will not undergo the procedure. This is known as a randomized trial. During the trial, all subjects will also get MRIs and fluid withdrawn from their knee joints at various timepoints in order to precisely figure out how the procedure works on a closer (microscopic) level.

Elbow Artery Embolization for Tennis Elbow
The purpose of this clinical research study is to examine whether embolization treatment of an elbow artery is a safe and effective way to treat elbow pain, specifically pain from tennis elbow. Embozene is a medical device made by Varian marketed in the United States for the treatment of hypervascular tumors and arteriovenous malformations. It consists of thousands of microscopic spheres that are injected into the artery to block the flow of blood to a specific region. One of the causes of pain in the setting of tennis elbow is increased blood flow going to the specific area of pain. In this study, we will investigate an experimental procedure to decrease the blood flow (embolize) to the specific region of the elbow that is causing the pain. This will be done by infusing Embozene particles into the specific blood vessel supplying the area of pain in the elbow. This is an investigational study to evaluate the safety and efficacy of elbow artery embolization (EAE) for the treatment of symptomatic lateral epicondylitis (tennis elbow).

Simultaneous Multinuclear Metabolic MRI in Newly Diagnosed or Recurrent Glioma
This clinical trial constructs and tests a novel multinuclear metabolic magnetic resonance imaging (MRI) sequence in patients with glioma (brain tumor) that is newly diagnosed or has come back (recurrent). This trial aims to develop new diagnostic imaging technology that may bridge gaps between early detection and diagnosis, prognosis, and treatment in brain cancer.

Integrating Quantitative MRI and Artificial Intelligence to Improve Prostate Cancer Classification
This study evaluates how new magnetic resonance imaging (MRI) and artificial intelligence techniques improve the image quality and quantitative information for future prostate MRI exams in patients with suspicious of confirmed prostate cancer. The MRI and artificial intelligence techniques developed in this study may improve the accuracy in diagnosing prostate cancer in the future using less invasive techniques than what is currently used.

Quantifying Body Composition and Liver Disease in Children Using Free-Breathing MRI and MRE
Magnetic resonance imaging (MRI) is used to measure liver fat content and fatty tissues in the body, and magnetic resonance elastography (MRE) is used to measure liver stiffness. The information from MRI and MRE are used to understand risk factors and diagnose liver diseases, such as fatty liver disease and liver fibrosis. However, current MRI and MRE scans need to be performed during a breath-hold, which may be challenging or impossible in children and infants. The goal of this research project is to develop and evaluate new free-breathing MRI and MRE technology to improve the comfort and diagnostic accuracy for children and infants.

MR Imaging and MR Spectroscopy of HIV (HIV)
The Center for Disease Control and Prevention estimates that 1,148,200 Americans aged 13 years and older are living with HIV infection, including 207,600 (18.1%) who are unaware of their infection. According to pathological data, central nervous system (CNS) involvement is commonly found during the early phase of infection. In vivo proton magnetic resonance spectroscopy studies of HIV-infected humans have demonstrated significant changes of metabolites observed in the brain N-acetylaspartate, creatine, choline, glutamate, glutamine and myo-inositol with varying changes in different brain regions. Diffusion tensor imaging (DTI) is a novel functional MRI technique which can be used to derive quantitative in vivo measurements of region-specific and diffuse brain alterations. DTI studies have demonstrated changes of mean diffusivity (MD) and fractional anisotropy (FA) in the various parts of brain. Diffusion abnormalities involving various regions of brain have also been observed in patients infected with HIV. One dimensional (1D) or two-dimensional (2D) magnetic resonance spectroscopic imaging (MRSI) technique has been used for many years to study the metabolites changes in HIV. MRI scan time necessary for the acquisition of high-resolution MRSI data with adequate spatial coverage may be prohibitively long for clinical exams. Thus, new imaging and bio-chemical characterization techniques are needed to allow repeated, non-invasive assessment of these processes in vivo. Since neuroinflammation is associated with increased brain water, diffusion tensor imaging (DTI) is sensitive to changes in white matter (WM) and inflammatory changes associated with HIV infections. Even though only single-voxel-based diffusion-weighted MRS has been previously investigated, altered diffusivity of non-water metabolites and its relationship with metabolic disturbance as well as structural and functional abnormalities in HIV has not been investigated. The brain apparent diffusion coefficient (ADC) changes of metabolites measured by the novel 3D MRSI technique will be correlated with the ADCs and fractional anisotrophy of water recorded by DTI and cell count to better understand the role of CNS involvement in HIV pathology.
