This study is for adults with **cutaneous lupus erythematosus (CLE)** or **systemic lupus erythematosus (SLE)**, which are diseases causing skin problems. The study medicine, **PF-06823859**, is being tested to see if it is safe and effective. It will compare this medicine to a placebo, which looks like the real medicine but has no active drug. About 48 participants will join, with 32 getting the real medicine and 16 receiving the placebo. All treatments are given through an **intravenous infusion**, meaning it’s injected into the veins.
Participants will be in the study for around **65 weeks**. This includes time for choosing participants, receiving treatment, and having follow-up visits. The study will see if the medicine helps improve the **CLASI-A score**, a measure of skin symptoms.
Key Points:
- The study lasts about 65 weeks, with regular visits and check-ups.
- Participants must have CLE or SLE with specific skin symptoms to join.
- Treatments are given by vein infusion, with some risks and requirements.
