ALN-PNP for MASLD and Healthy Adults

This study is testing an experimental drug called ALN-PNP. It's a "first-in-human" study, meaning it's the first time this drug is being given to people. The drug is not yet approved by health agencies like the FDA. The main goal is to see how safe ALN-PNP is and how well people tolerate it. Researchers will also look at potential side effects. You might be able to join if you are a healthy adult or an adult with Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), especially if you have a specific gene variant. Some parts of the study focus on healthy adults, while others focus on those with MASLD. This study is currently recruiting up to 172 participants.
