NCT06691659
This project aims to develop and evaluate a next-generation photon-counting CT prototype, and assess whether next-generation photon-counting CT--which enables reduced radiation dose, high spatial resolution, and spectral imaging--would facilitate improved diagnostic performance for abdominal, cardiothoracic, musculoskeletal, and neuroimaging.
NCT04856410
This study investigates the effects of extended-duration spaceflight (12-month International Space Station missions) on general cognitive performance (measured with the Cognition test battery), spatial cognition, structural and functional brain changes in general, and hippocampal plasticity more specifically relative to the shorter 6-month and 2-month missions.
NCT04494256
The ALSpire Study is a clinical trial evaluating the investigational drug BIIB105 in adults living with amyotrophic lateral sclerosis (ALS). The ALSpire Study consists of two parts: * Part 1: 6-month placebo-controlled study. During Part 1, participants are randomly assigned to receive either BIIB105 or placebo in a 3:1 or 2:1 ratio (depending on the participant's assigned Cohort). * Part 2: up to 3-year long-term open-label extension. During Part 2, all participants receive BIIB105. The objectives of the study are to evaluate: * The safety and tolerability of BIIB105 in people with ALS * What the body does to BIIB105 (also called "pharmacokinetics") * What BIIB105 does to the body (also called "pharmacodynamics") * Whether BIIB105 can slow the worsening of clinical function
