Eligibility
Key inclusion criteria
Part 1

* Diagnosis of Systemic Lupus Erythematosus (SLE) according to the 2019 European League Against Rheumatism (EULAR)/ American College of Rheumatology (ACR) criteria
* Diagnosis of International Society of Nephrology/ Renal Pathology Society (ISN/RPS) 2003 Class III or IV LN as evidenced by renal biopsy performed within 1 year prior to or during screening, either with or without the presence of Class V LN
* Proteinuria (urine protein to creatinine ratio) > 1.0 gram per gram (g/g), based on 24-hour urine collection during screening
* eGFR = 45 milliliter/minute/1.73 square meters (mL/min/1.73 m^2) (as calculated by the Chronic Kidney Disease Epidemiology Collaboration formula)

1. If eGFR is =35 to <45 mL/min/1.73m^2, renal biopsy must be within 6 months of screening and must not have >50% of glomeruli with sclerosis. If the renal biopsy was performed more than 6 months prior to screening, a repeat biopsy must be done during screening after all the other eligibility criteria are met
2. If eGFR is =45 mL/min/1.73 m^2, renal biopsy must be within 1 year prior to screening. If the renal biopsy was performed more than 1 year prior to screening, a repeat biopsy must be done during screening after all the other eligibility criteria are met
* History of inadequate response, for lack of efficacy or intolerance, to at least a three-month course of one standard of care treatment for lupus nephritis, as determined by the treating physician

Part 2

* Participants must complete Part 1 of the study to be eligible to participate in Part 2.
Minimum age
18 Years
Maximum age
75 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Part 1

* Presence of rapidly progressive glomerulonephritis, as defined by at least one of the following: crescent formation in > 50% of glomeruli on renal biopsy, sustained doubling of serum creatinine within 12 weeks of screening, or the investigator's opinion that the participant has rapidly progressive glomerulonephritis
* Greater than 50% of glomeruli with sclerosis on renal biopsy
* Currently requiring hemodialysis or peritoneal dialysis or expected to require dialysis during the study treatment period
* A previous kidney transplant or other organ transplant, or planned transplant within study treatment period

Part 2

* Did not complete Part 1 of the study
* Received protocol-prohibited medications in Part 1 such as calcineurin inhibitors (e.g., cyclosporine, tacrolimus, or voclosporin), alkylating agents including cyclophosphamide, or biologic agents other than felzartamab
* Progression of LN (as measured by worsening proteinuria and/or decreasing eGFR) has been observed such that in the opinion of the investigator the participant will not benefit from continuing in Part 2 of the study

Other protocol-defined inclusion/exclusion criteria may apply.
