This study is testing a new treatment called **CC-97540** (also known as _Zola-cel_), for people with active **systemic lupus erythematosus (SLE)**, which is a disease where the immune system attacks its own body. The study is for people whose SLE is not getting better with current medicines like **glucocorticoids** (steroids) and at least two other medicines that help calm the immune system.

To join the study, you need to have SLE, not be getting better with your current medicines, and have active disease. If you have other serious health problems or have had certain types of cancer in the past two years, you may not be able to join. You also cannot join if you've had certain types of therapies like CAR T cell therapy or organ transplants before.

• Study Duration: Must use certain medicines for at least 3 months.
• Risks: Cannot have other serious health conditions.
• Requirements: Cannot have received live vaccines recently.
