About the study

The primary objectives of the study are to evaluate the efficacy of BIIB059 (litifilimab) compared with placebo in reducing skin disease activity measured by the Cutaneous Lupus Activity of Physician's Global Assessment-Revised (CLA-IGA-R) score [Parts A and B (US)] and the Cutaneous Lupus Erythematosus Disease Area and Severity Index Activity (CLASI-A) score [Part B (ROW)] in participants with active SCLE and/or CCLE with or without systemic manifestations and refractory and/or intolerant to antimalarials. The secondary objectives of the study are to evaluate the efficacy of BIIB059 in reducing SCLE and/or CCLE disease activity by CLA-IGA-R, CLASI-A; to evaluate additional efficacy parameters of BIIB059 in reducing SCLE and/or CCLE disease activity; safety; tolerability; and immunogenicity of BIIB059 [Parts A and B].
