An Ascending Dose Study of PIT565 in Participants With Systemic Lupus Erythematosus (SLE).

To join this study, you must be between 18 and 75 years old and have been diagnosed with lupus (SLE) using specific medical guidelines. Your lupus should also be active, meaning you are currently experiencing symptoms, and your current lupus treatments should not be working well enough.

You would not be able to join if you have very severe lupus that has caused significant organ damage or is life-threatening, or if you are having a serious flare-up that needs immediate treatment. Also, if you have severe kidney problems related to lupus that require strong medication, you might not be suitable. Other conditions like serious heart problems, certain severe infections (like HIV or hepatitis), or other serious medical illnesses could also prevent you from taking part.

Women who could become pregnant would need to be using very reliable birth control methods to be considered for the study.

If you decide to take part, you would receive the study medicine, PIT565, as an injection under your skin. Before each dose, you might receive other medicines to help prevent any reactions. The study involves different groups of people, and the dose of PIT565 might be different for each group, starting low and possibly increasing if it's safe.

The researchers will closely monitor your health and any effects of the medicine. This will involve regular visits to the clinic for check-ups, blood tests, and other assessments. The total time you would be involved in the study is not specified, but early-stage studies like this often involve several weeks or months of close monitoring.
