Lupus is an autoimmune disease that attacks organs and can be fatal. There’s no cure, so current treatments aim to limit damage and ameliorate symptoms. Some of these therapies have to be injected, some have serious side effects, and many aren’t very effective. But today, scientists report they have begun phase 2 clinical trials with a pill containing a compound that, in mice, not only prevents lupus-like symptoms, but also reverses signs of organ damage caused by the disease and prevents death.
