• Diagnosis of drug-induced SLE rather than idiopathic SLE.
• Other systemic autoimmune diseases (eg, multiple sclerosis, psoriasis, inflammatory bowel disease, etc) are excluded. Participants with type I autoimmune diabetes mellitus, thyroid autoimmune disease, Celiac disease, or secondary Sjögren's syndrome are not excluded.
• SLE overlap syndromes including, but not limited to, rheumatoid arthritis, scleroderma, and mixed connective tissue disease, are excluded.
• Recent or present clinically significant CNS pathology.
• IIM disease activity. i) Other forms of IIM: Inclusion Body Myositis, Amyopathic DM, any form of juvenile myositis. ii) Myositis other than IIM, eg, drug-induced myositis and PM associated with HIV. iii) Participants with severe muscle damage (Physician VAS for muscle damage in Myositis Damage Index > 7 cm on a 10 cm scale), permanent weakness due to a non-IIM cause (eg, stroke), or myositis with cardiac involvement.
• SSc disease activity. i) SSc related PAH requiring active treatment. ii) Rapidly progressive SSc related lower GI (small and large intestines) involvement (requiring parenteral nutrition); active gastric antral vascular ectasia. iii) Prior scleroderma renal crisis.
• Other protocol-defined Inclusion/Exclusion criteria apply.
