Condition/Disease

Primary Membranous Nephropathy

Objectives

Primary Objective: Evaluate the efficacy of felzartamab compared to tacrolimus in achieving complete remission (CR) of proteinuria in PMN participants. Secondary Objective: Further evaluate the efficacy of felzartamab through additional clinical endpoints and time points. Evaluate the effect of felzartamab on serum anti-PLA2R antibodies. Evaluate the safety of felzartamab. Evaluate the effect of felzartamab on patient-reported outcomes. Evaluate the pharmacokinetics of felzartamab. Evaluate the immunogenicity of felzartamab.

Test Drug

Injectable frozen powder

Active Ingredient

Felzartamab

Dosage Form

048

Dosage

325 mg/vial

Endpoints

The percentage of participants who achieved complete remission (CR) at week 104. CR was defined as a urine protein/creatinine ratio (UPCR) ≤ 0.3 g/g (based on 24-hour sample collection), stable estimated glomerular filtration rate (eGFR) [eGFR decrease from baseline ≤ 15%], and serum albumin > 3.5 g/dL.

Inclution Criteria

Key Inclusion Criteria:

Diagnosed with PMN in need of IST according to the Investigator's clinical judgment. The diagnosis of PMN must be documented with the presence of nephrotic syndrome, and hypoalbuminemia, and confirmed with a kidney biopsy either during Screening or within 5 years of signing the informed consent form (ICF) [see kidney biopsy exception below for participants positive for anti-PLA2R antibodies]. For these participants, the biopsy report with redacted protected health information must be available to be reviewed by the Sponsor or an independent nephropathologist. If the participant requires a kidney biopsy during Screening, medical monitor approval must be obtained and all other eligibility criteria should be reviewed to ensure that the participant is otherwise eligible prior to performing the kidney biopsy.

a. Kidney biopsy exception for anti-PLA2R antibody positive participants: Participants who are positive for anti-PLA2R antibodies and have not had a kidney biopsy performed within 5 years of signing the ICF, may be eligible for the study without undergoing a kidney biopsy based on medical monitor review confirming normal estimated glomerular filtration rate (eGFR), presence of nephrotic syndrome, hypoalbuminemia, positive anti-PLA2R antibody test (defined as an anti-PLA2R antibody titer > 20 RU/mL), and documentation provided by the Investigator that the work-up for secondary causes of membranous nephropathy (MN) was negative with no identifiable secondary causes.

Meets one of the following:

Newly diagnosed PMN, defined as having never received IST for PMN in the past.
Relapsed PMN, defined as documented achievement of CR or partial remission (PR) after treatment with an IST for PMN followed by reappearance of nephrotic range proteinuria (urine protein to creatinine ratio [UPCR] ≥ 3.0 gram per gram [g/g] from a 24-hour urine collection or proteinuria ≥ 3.5 gram per 24 hour [g/24 h]).
Participants must be on the maximally approved dose or maximally tolerated dose of angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) for at least 3 months prior to Screening. Participants not on the maximally approved dose of renin-angiotensin-aldosterone system (RAAS) inhibition may be enrolled provided there is documented intolerance to maximal RAAS inhibition (e.g., angioedema, development of postural hypotension, lightheadedness, hyperkalemia, etc).
A UPCR of ≥ 3.0 g/g (as determined by a 24-hour urine collection) or total proteinuria ≥ 3.5 g/24 h (as determined by a 24-hour urine collection) at Screening after best supportive care for at least 3 months prior to signing the ICF.

Exclusion Criteria

Key Exclusion Criteria:

Secondary cause of MN (e.g., malignancies, medications, systemic lupus erythematosus [SLE], hepatitis B, hepatitis C, etc).
Severe renal impairment defined as an eGFR ≤ 30 mL/min/1.73m^2 at Screening or including the need for dialysis or renal replacement therapy.
Note: Other protocol-defined Inclusion/Exclusion criteria may apply.
