Abstract
The paradigm of drug approval in SLE currently relies on successful large phase III randomised controlled trials and a set of primary, secondary and additional end points. Taken together, these outcomes offer a nuanced understanding of the efficacy and safety of the investigational agent. In this review, we thoroughly examine the main outcomes used in SLE trials and highlight unmet requirements as well as potential venues for future trial design in SLE. Disease activity indices can be broadly categorised into global-specific and organ-specific indices, in particular for skin, joints and kidneys, but there is no universal consensus about their use in clinical trials. Because each of these instruments has its own intrinsic strengths and weaknesses, the assessment of treatment response has progressed from relying solely on one individual disease activity index to using composite responder definitions. Those are typically measured from the trial baseline to the end point assessment date and may be combined with the need to taper and maintain glucocorticoids (GCs) within prespecified ranges. Remission and low disease activity are two critical states in the perspective of 'Treat-to-Target' trials, but are not fully recognised by regulators. While significant progress has been made in clinical trial outcomes for SLE, there is a clear need for continued innovation. Addressing these challenges will require collaboration between researchers, clinicians, patients as well as with regulatory agencies to refine existing outcome measures, incorporate meaningful and ethnically diverse patient perspectives, foster relevant digital opportunities and explore new therapeutic avenues, including early use of investigational agents. By doing so, we can advance our ability to manage SLE effectively and safely and improve the lives of those living with this complex and impactful autoimmune disease.

Abstract
INTRODUCTION There are no U.S. Food and Drug Administration (FDA) approved therapies for cutaneous lupus erythematosus (CLE). Litifilimab is a monoclonal antibody against BDCA2, a plasmacytoid dendritic cell specific antigen, currently under investigation for systemic lupus erythematosus (SLE) and CLE. The LILAC study, published in the New England Journal of Medicine, is a phase II randomized controlled trial for CLE which demonstrated superiority of Litifilimab over placebo using a skin directed outcome measure. AREAS COVERED This review identifies challenges that have hindered the development of any approved treatments for CLE, recent SLE trials that include skin disease data, and the pharmacological properties of litifilimab. We review the clinical efficacy and safety of litifilimab for both SLE and CLE in the phase I and II clinical trials. This review aims to highlight the need for more CLE specific clinical trials and examine the potential of litifilimab as the first FDA approved therapy for CLE. (Clinical trial registration: www.clinicaltrials.gov identifier is NCT02847598.). EXPERT OPINION Litifilimab demonstrated efficacy in a randomized phase II clinical trial as a standalone CLE trial using validated skin specific outcome measures, making it the first successful clinical trial for a CLE targeted therapy. If approved, litifilimab will be a pivotal change in the landscape of CLE management especially for severe and refractory disease.

Abstract
There have been important developments in defining cutaneous lupus erythematosus and dermatomyositis. The skin manifestations of these two diseases have a profound impact on QOL, with both emotional and symptomatic impacts that are important to address. The proliferation of potential therapeutic targets has made it important to make sure that these diseases are defined in a way that they can be included in translational and clinical studies of both localized and systemic forms of the diseases. There are now validated disease tools and QOL studies that are facilitating current and future scientific and therapeutic developments.

Abstract
Reliable and responsive outcome measures that accurately detect changes in disease state, activity, and damage are crucial to conducting observational and interventional trials that can directly transform care for children with rheumatic disease. A combination of consensus-based and direct measurement approaches has led to the development of several validated, composite outcome measures in juvenile idiopathic arthritis, juvenile dermatomyositis, childhood-onset systemic lupus erythematosus, and pediatric vasculitis. This review outlines clinician-reported, disease-specific outcome measures developed for these conditions.

Abstract
Juvenile systemic lupus erythematosus (JSLE) is characterised by onset before 18 years of age and more severe disease phenotype, increased morbidity and mortality compared to adult-onset SLE. Management strategies in JSLE rely heavily on evidence derived from adult-onset SLE studies; therefore, identifying biomarkers associated with the disease pathogenesis and reflecting particularities of JSLE clinical phenotype holds promise for better patient management and improved outcomes. This narrative review summarises the evidence related to various traditional and novel biomarkers that have shown a promising role in identifying and predicting specific organ involvement in JSLE and appraises the evidence regarding their clinical utility, focusing in particular on renal biomarkers, while also emphasising the research into cardiovascular, haematological, neurological, skin and joint disease-related JSLE biomarkers, as well as genetic biomarkers with potential clinical applications.

Abstract
Cutaneous lupus erythematosus (CLE) can present with or without features of systemic lupus erythematosus (SLE), with estimates of the incidence of isolated skin disease almost equaling the incidence of those with systemic disease. However, despite the impact CLE has on a patient’s quality of life (QoL), there has been no US Food and Drug Administration (FDA) approved treatment for the disease in the past 50 years. In addition, patients with skin predominant LE are often excluded from clinical SLE trials. In the rare trials that include patients with skin predominant LE, disease activity and progression in the skin are often difficult to evaluate using multi-organ outcome measures. The need for new therapies for CLE and the lack of focus on skin outcomes has led to the development of the Cutaneous Lupus Disease Area and Severity Index (CLASI), a validated organ-specific outcome measure that is not only responsive to change in disease activity and damage but also correlated to changes in a patient’s QoL. This paper will emphasize the extensive validation studies performed in developing the CLASI, as well as the importance of clinical trials using the CLASI to address the need for improved therapies for patients with lupus skin manifestations.
