The STI-6129-001 study is a three-stage, multicenter, open-label, dose-finding, phase 1b/2a trial. It is designed primarily to identify the recommended phase 2 dose (RP2D) of STI-6129 by assessing the safety, preliminary efficacy and pharmacokinetics of this anti-CD38-Duostatin 5.2 antibody-drug conjugate (ADC) for the treatment of relapsed or refractory systemic AL amyloidosis. The patients that will be treated with STI-6129 in this trial are relapsed or refractory systemic AL amyloidosis patients who have received prior lines of treatment. Read Less

The investigators have developed a new technology, termed in-vivo laser capture microdissection (IVLCM), that addresses the limitations of endoscopic biopsy for screening for BE and provides targeted genomic profiling of aberrant tissue for more precise prediction of EAC risk. The device is a tethered capsule endomicroscope (TCE) that implements optical coherence tomography (OCT) to grab 10-mm-resolution, cross-sectional microscopic images of the entire esophagus after the capsule is swallowed. This OCT-based TCE technology is used in unsedated patients to visualize images of BE and dysplastic BE. During the IVLCM procedure, TCE images of abnormal BE tissue are identified in real time and selectively adhered onto the device. When the capsule is removed from the patient, these tissues, targeted based on their abnormal OCT morphology, are sent for genomic analysis. By enabling the precise isolation of aberrant esophageal tissues using a swallowable capsule, this technology has the potential to solve the major problems that currently prohibit adequate BE screening and prevention of Esophageal Adenocarcinoma EAC.

In this study, we investigate the impact of insulin resistance on the acceleration of brain aging, and test whether increased neuron insulin resistance can be counteracted by utilization of alternate metabolic pathways (e.g., ketones rather than glucose). This study has three Arms, which together provide synergistic data. For all three Arms, subjects are tested in a within-subjects design that consists of 2-3 testing sessions, 1-14 days apart, and counter-balanced for order. During each session we measure the impact of fuel (glucose in one session, ketones in the other) on brain metabolism and associated functioning. For Arms 1-2, our primary experimental measure is functional magnetic resonance imaging (fMRI), which we will use to trace the self-organization of functional networks following changes in energy supply and demand. Arm 1 tests the impact of endogenous ketones produced by switching to a low carbohydrate diet, while Arm 2 tests the impact of exogenous ketones consumed as a nutritional supplement. For Arm 3, we use simultaneous magnetic resonance spectroscopy/positron-emission tomography (MR/PET) to quantify the impact of exogenous ketones on production of glutamate and GABA, key neurotransmitters. Subjects will be given the option to participate in more than one of the Arms, but doing so is not expected nor required. Prior to scans, subjects will receive a clinician-administered History and Physical (H&P), which includes vital signs, an oral glucose tolerance test (OGTT), and the comprehensive metabolic blood panel. These will be used to assess diabetes, kidney disease, and electrolytes. If subjects pass screening, they will be provided the option to participate in one or more Arms, which include neuroimaging. To provide a quantitative measure of time-varying metabolic activity throughout the scan, based upon quantitative models of glucose and ketone regulation, as well as to be able to implement safety stopping rules (see below), we will obtain pin-prick blood samples three times: prior to the scan, following consumption of the glucose or ketone drink, and following completion of the scan. To assess effects of increased metabolic demand, we measure brain response to cognitive load, transitioning from resting-state to spatial reasoning through a Tetris task. To assess effects of increased metabolic supply, we measure brain response to glucose or ketone bolus. Read Less

The goal of this study is to determine if a mind-body intervention can help people suffering from chronic back pain. The study is a randomized, partially blinded trial examining the effectiveness of a mind body intervention in reducing disability from back pain and alleviating back pain in participants as compared to usual care and an active control (second mind body intervention). The investigators will secondarily investigate whether the intervention alleviates anxiety related to the pain and other quality of life parameters. Read Less

Almost 18 million US adults have alcohol use disorders (AUD), with one third of these individuals also diagnosed with anxiety disorders (AXD). The coexistence of AUD and AXD imposes a high burden via healthcare costs and lost productivity. To date, existing treatment approaches for addressing AUD/AXD comorbidity have been only modestly effective and there is a lack of adequate research to guide treatment decisions. The Unified Protocol (UP) is a transdiagnostic, cognitive-behavioral therapy that has shown efficacy in treating emotional disorders. The efficacy of the UP to facilitate abstinence from alcohol consumption in individuals with comorbid AUD/AXD has also been examined, with results from this study indicating a reduction from baseline in drinks consumed per day. However, further evaluation of the UP for managing AUD/AXD is warranted. In this clinical trial, the investigators will further assess the UP's effectiveness in reducing alcohol consumption in patients with comorbid AUD/AXD. Participants will be randomized to one of two conditions: 1) treatment with the UP or 2) treatment with therapist-guided Take Control (TC; a computerized alcohol reduction program). In addition, in a subset of twenty-five participants, functional magnetic resonance scanning (fMRI) will be used to examine the effects of the UP on changes in brain activity in areas important to regulation of emotional and reward processes implicated in excessive alcohol consumption. The researchers' primary hypotheses are that the UP group will, compared to the TC group: 1) be superior in acute symptom reduction from pre- to post-treatment, and 2) evidence greater reductions in percent days heavy drinking, percent days of drinking per week, and alcohol craving.

The Rett Syndrome Registry is a longitudinal observational study of individuals with MECP2 mutations and a diagnosis of Rett syndrome. Designed together with the IRSF Rett Syndrome Center of Excellence Network medical directors, this study collects data on the signs and symptoms of Rett syndrome as reported by the Rett syndrome experts and by the caregivers of individuals with Rett syndrome. This study will be used to develop consensus based guidelines for the care of your loved ones with Rett syndrome and to facilitate the development of better clinical trials and other aspects of the drug development path for Rett syndrome.

The investigators propose a robust therapeutic intervention to ameliorate myocardial ischemia/ reperfusion injury and significantly decrease morbidity and mortality in patients requiring extracorporeal membrane oxygenation (ECMO), by direct injection of autogeneic mitochondria into the ischemic myocardium.

This study is a postmarketing requirement jointly carried out by four NDA holders (Bayer AG, Bracco, GE Healthcare and Guerbet) and the CRO IQVIA. The study aims to create detailed images of the organs and tissue of the human body during x-ray, CT-scan or MRI investigations, doctors are using contrast media (a kind of dye) which can be given to patients by injection into a blood vessel or by mouth. In this study researchers want to find out whether so called gadolinium-based contrast agents (GBCAs) have an effect on body movement and mental skills when given to participants multiple times within 5 years. The study plans to enroll about 2076 participants suffering from a condition for which they are likely to have at least annually a MRI or another imaging examinations. Only adults up to 65 years will be considered to join this study. During the study duration of 5 years participants will receive annually a MRI or other imaging tests (such as CT-scan, x-ray) and will visit the study doctor at least 7 times for physical examinations, laboratory investigations and tests on body movement and mental skills.
