Purpose

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].

Experimental
Part A (Phase 2): BIIB059 		Participants will receive BIIB059 subcutaneously (SC) once every 4 weeks (Q4W) from Week 0 to Week 20, with an additional dose of BIIB059 at Week 2 during the double-blind placebo-controlled (DBPC) treatment period. Following the DBPC treatment period, participants will receive BIIB059 during the extended treatment period (ETP) from Week 24 to Week 48, with an additional dose of BIIB059-matching placebo at Week 26.
