Inclusion criteria

* Participants must meet EULAR/ACR 2019 criteria for SLE. * Participants must have an inadequate response to appropriate doses of glucocorticoids and ≥ 2 immunosuppressant therapies, used for at least 3 months. * Participants must have active disease when signing ICF.

Exclusion criteria

* Participants must not have other diseases, conditions, or treatments that may confound interpretation of the effects of CC-97540 in SLE. * Uncontrolled or clinically significant cardiovascular conditions or CNS pathology participants must not have prior history of malignancies or lymphoproliferative disease, unless the participant has been free of the disease for ≥ 2 years, except for some non-invasive malignancies. * IOCBP who are pregnant, nursing, or breastfeeding, or who intend to become pregnant. * Participants must not have prior treatment with CAR T cell therapy, genetically modified T cell therapy, stem cell transplant or organ transplant. * Participants must not have received live vaccines within 6 weeks before LDC (lymphodepleting chemotherapy) administration. * Participant must not have inadequate organ function. * Other protocol-defined inclusion/
