ClinConnect Summary

This clinical trial is studying a new medication called GSK4527363 to see how safe it is and how it works in different groups of people. The trial involves three parts: healthy adults, people with systemic lupus erythematosus (SLE), a condition where the body's immune system attacks its own tissues, and healthy participants of Chinese and Japanese descent. Researchers want to learn about the safety of the medication, how it is absorbed and processed by the body, and whether it triggers any immune responses.

To participate, healthy adults need to be between 18 and 55 years old, in good health, and meet specific criteria regarding their medical history. Those with SLE should be between 18 and 65 years old and have a confirmed diagnosis of SLE. Participants can expect to undergo health evaluations, take the medication, and be monitored for any side effects. It’s important to note that individuals with certain health issues or recent infections may not be eligible to participate. This study is currently recruiting participants, and it aims to help improve understanding and treatment options for SLE.
