New lupus drug shows promise in Long-Term safety trial
NCT ID NCT05352919
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 13 times
Summary
This study looks at the long-term safety of a drug called litifilimab for people with active lupus. About 864 adults who finished earlier studies will continue taking the drug for up to 3 years, along with their usual treatments. The goal is to see how safe it is and how well it controls lupus symptoms. This is not a cure, but it may help manage the disease better.
This is an AI summary of the original study and may miss details. Read our disclaimer.
