Primary | Count Of Participants Reporting Treatment-emergent Adverse Events (TEAEs) | A TEAE was defined as any adverse event (AE) that starts on or after the first dose of study drug or occurs prior to the first dose and worsens in severity on or after the first dose of study drug, during the Treatment Period and Follow-up Period. A TEAE was considered "serious" (Grade 3) if, in the view of either the investigator or sponsor, it resulted in any of the following outcomes: death, life-threatening adverse drug event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, congenital anomaly/birth defect, or an event that may have jeopardized the participant and may have required medical or surgical intervention to prevent one of the previously listed outcomes. A summary of serious and all other non-serious adverse events, regardless of causality, is located in the Reported Adverse Events module. | Day 1 (after first dose) through Day 112 | |
Secondary | Maximum Percent Reduction Of Mean Total Immunoglobulin G (IgG) Levels From Baseline | Pharmacodynamic samples were collected for analysis throughout the study. The maximum percent reduction of mean serum total IgG levels from Baseline observed during the study is presented. | Baseline through Day 112 | |
Secondary | Maximum Percent Reduction In Mean Pemphigus Disease Area Index (PDAI) Total Activity Score From Baseline | Pemphigus severity and disease activity was measured using the PDAI in regions where a validated questionnaire was available. The PDAI was administered during Treatment Period and Follow-up Period. PDAI total activity was comprised of scores for the skin, mucous membrane, and scalp subscales. The investigator determined a PDAI score as 0 to 250 points for total activity score (0 to 120 for skin, 0 to 10 for scalp, and 0 to 120 for mucosa). A higher score indicated higher impact on skin disease. The maximum percent reduction in PDAI total activity score from Baseline observed during the study is presented. | Baseline through Day 112 | |
Secondary | Maximum Percent Reduction Of Mean Circulating Immune Complexes (CIC) Levels From Baseline | Pharmacodynamic samples were collected for analysis throughout the study. The maximum percent reduction of mean CIC levels from Baseline observed during the study is presented. | Baseline through Day 112 | |
Secondary | Maximum Percent Reduction Of Mean Anti-Desmoglein (Dsg) 1 And 3 Antibodies From Baseline | Pharmacodynamic samples were collected for analysis throughout the study. The maximum percent reduction of mean anti-Dsg 1 and 3 antibodies from Baseline observed during the study is presented. | Baseline through Day 112 |
