ClinConnect Summary

This clinical trial is studying a medication called liposomal amphotericin B, which is used to treat serious fungal infections, including those in patients with weakened immune systems and certain tropical diseases. The goal of the study is to see how well this new version of the drug works compared to the standard product (AmBisome®) in healthy individuals. The trial will take place at a single center and will involve giving participants a single dose of the medication to assess its effects and safety.

To be eligible for this trial, participants need to be healthy Chinese men and women aged 18 to 55, with specific weight and height requirements. They must also be able to understand the trial process and agree to participate by signing a consent form. During the study, participants will be monitored for safety and any potential side effects. It's important to note that there are several criteria that could exclude someone from participating, such as having certain health conditions, recent drug use, or specific dietary needs. If you or someone you know is interested, it’s best to discuss eligibility with the study team.
