NCT07414212
This study is designed to evaluate whether a combination of N-acetylcysteine (NAC) and EH-301 can slow down or improve symptoms of amyotrophic lateral sclerosis (ALS). Researchers will assess changes in disease progression using the ALS Functional Rating Scale-Revised (ALSFRS-R), a standard tool for measuring daily functioning in people with ALS. The main question is whether taking NAC together with EH-301 can prevent symptom worsening and possibly improve existing ALS symptoms. Participants will be randomly assigned to receive either the active combination (NAC + EH-301) or matching placebos for 6 months. During this period, they will attend regular clinic visits for evaluations, tests, and safety monitoring. After completing the initial 6-month phase, all participants may choose to join a 6-month open-label extension, where everyone receives the active treatment regardless of their original group.
NCT05661916
The purpose of this study is to evaluate the safety, tolerability, pharmacodynamics (PD) and pharmacokinetics (PK) of single ascending doses of ALN-TTRSC04.
NCT01862731
Background: \- Researchers are interested in how the muscles affect the movement of the knee cap. These muscles may be related to different kinds of knee pain that are not caused by an injury or a disease. Imaging studies such as magnetic resonance imaging (MRI) can be used to look at these muscles. To study these muscles and how they move, researchers will use MRI to look at healthy individuals and individuals with knee cap pain. Objectives: \- To study how changes to the muscles around the knee can influence knee pain. Eligibility: * Individuals between 18 to 55 years of age who have knee cap pain that cannot be explained by a specific injury or disease. * Healthy volunteers between 18 and 55 years of age. Design: * Participants will be screened with a physical exam and medical history. * This study requires two visits. Each visit will use standard MRI sequences to take images of the knee in motion and at rest. * On the first visit, the MRI scan will look at the knee in its natural state. Participants will move the knee up and down for 1 to 3 minutes at a time during the scan. * On the second visit, a local anesthetic agent will be injected into the muscle of the thigh. The anesthetic will block this muscle from generating force for 2 or 3 hours. Participants will move the knee up and down for 1 to 3 minutes at a time during the MRI scan.
