Overview

A Study to Assess the Efficacy and Safety of BIIB059 in Participants With Active Subacute Cutaneous Lupus Erythematosus (SCLE) and/or Chronic Cutaneous Lupus Erythematosus (CCLE) With or Without Systemic Manifestations and Refractory and/or Intolera

Summary
The primary objectives of the study are to evaluate the efficacy of BIIB059 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].

Key Exclusion Criteria:

1. Any active skin conditions other than CLE that may interfere with the study
assessments of CLE.

2. Active severe lupus nephritis.

3. Active neuropsychiatric SLE.

4. Use of immunosuppressive or disease-modifying treatments for SLE or CLE [via an oral,
