(Serious) adverse events will be classified using the Medical Dictionary for Regulatory Activities (MedDRA). Documentation of an AE will include the assessment of its relationship with the study drug (unrelated, related) and the severity of AE will be graded on a three-point scale (mild, moderate, severe).
Proteinuria is high levels of protein in the urine and is measured by UPCR. Relative change in UPCR was estimated based on mixed effects model for repeated measure (MMRM) model. Least squares (LS) mean and standard error (SE) were reported. The reference proteinuria value before start of treatment is defined as the mean of the values determined at screening and prior to baseline (visit 2) predose (UPCR from 24h urine). Negative change from baseline indicates less proteinuria.

An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAEs were defined as death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized participant and required medical intervention to prevent 1 of the outcomes listed in this definition. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section.

MOR202 is being developed for membranous nephropathy, a form of glomerulonephritis, specifically in patients who test positive for anti-PLA2R antibodies. It is an investigational monoclonal antibody studied in adults with this autoimmune kidney condition. The clinical program has focused on anti-PLA2R positive membranous nephropathy.
MOR202 is being developed by Biogen Inc., which trades on the Nasdaq under the ticker BIIB. Biogen is the sponsor of the clinical trials evaluating MOR202 in membranous nephropathy.
MOR202 is in Phase 2 clinical development. A Phase 2 trial in anti-PLA2R positive membranous nephropathy has been completed, and a Phase 1 trial in the same condition has also been completed. MOR202 is investigational and has not been approved for any indication.
MOR202 has been studied in two completed trials: NCT04733040, a Phase 2 trial titled Efficacy, Safety and PK/PD of MOR202 in Anti-PLA2R+ Membranous Nephropathy (NewPLACE), which enrolled 24 patients, and NCT04145440, a Phase 1 trial assessing safety and efficacy in anti-PLA2R positive membranous nephropathy, which enrolled 31 patients.
No, MOR202 is not FDA approved. It is an investigational monoclonal antibody that has completed Phase 1 and Phase 2 clinical trials in anti-PLA2R positive membranous nephropathy. Approval status has not been granted for any indication.
