A Treatment Effectiveness Study Among SLE Patients Receiving Anifrolumab in Routine Clinical Practice

Sponsor: AstraZeneca

Sommario: Anifrolumab Study of Treatment Effectiveness in the Real World (ASTER) study will collect real world data to obtain a good understanding of the (sustained) clinical effect and patient quality of life outcomes among diagnosed SLE patients who initiate anifrolumab treatment. ASTER will generate critical real-world evidence on the benefits of adding anifrolumab to standard of care treatment for SLE in routine clinical practice, to inform physicians, payers and patients.

TRATTAMENTO


OBIETTIVO PRIMARIO

  • Misura: Disease activity assessed by the Physician Global Assessment (PGA)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The PGA is a single-item visual analogue scale that describes the physician assessment of a patient's disease and its impact on daily functioning at the time of assessment. The scale ranges from 0 (asymptomatic disease and no limitation of normal activities) to 3 (severe disease and limitation of normal activities).
  • Misura: Disease activity assessed by Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The SLEDAI-2K is a global index and includes 24 clinical symptoms and laboratory variables that are weighted by the type of manifestation, but not by severity or dynamic of the individual item. The SLEDAI-2K includes scoring for antibodies and low complement, as well as some renal and hematologic parameters. The total score ranges between 0 and 105, with higher scores representing increased disease activity.
  • Misura: Proportion of patients attaining the composite endpoint of lupus low disease activity (LLDAS)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The proportion of patients attaining the composite endpoint of LLDAS will be assesed.

OBIETTIVO SECONDARIO

  • Misura: Clinical SLE Flares assessment by modified revised Safety of Estrogens in Lupus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) flare index (rSFI)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: Flare will be defined as any one criterion present either the Mild/Moderate Flare or Severe Flare categories. New or worsened manifestation will only be reported for manifestation of SLE.
  • Misura: Proportion of patients with irreversible organ damage, using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI).
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The proportion of patients with irreversible organ damage, using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index will be assessed. The irreversible, accumulated organ damage from either the disease process or disease treatment, which has been present for at least 6 months, in 12 organ systems will be measured.
  • Misura: SLE treatment patterns prior to, concomitant with and after anifrolumab
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: SLE treatment patterns will be analyzed through prevalence and incidence in respect to time to discontinuation.
  • Misura: Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-Fatigue)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The FACIT-Fatigue is a 13-item questionnaire formatted for self-administration that assesses patient-reported fatigue and its impact upon daily activities and function over the past 7 days. Patients will be asked to answer each question using a 5-point verbal rating scale, with total scores ranging from 0 (most fatigued) to 52 (least fatigued).
  • Misura: Lupus Quality of Life (LupusQoL)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The LupusQoL is a validated SLE-specific HRQoL (health-related quality of life) instrument consisting of 34 items across 8 domains (Physical health, Emotional health, Body image, Pain, Planning, Fatigue, Intimate relationships, and Burden to others). The LupusQoL has a 5-point verbal rating scale, and uses a 4-week recall period. The mean raw domain score is transformed to scores ranging from 25 (worst HRQoL) to 125 (best HRQoL) by dividing by 4 and then multiplying by 100.
  • Misura: Patient Global Assessment (PtGA)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The PtGA is a single-item question that takes into account all the ways in which illness and health conditions may affect the patient at this time. The patient should consider the previous week when answering this question. Responses range from 0 (Very Well) to 100 (Very Poorly) on a visual analogue scale (VAS).
  • Misura: EuroQol 5-Dimension Health Questionnaire 5 Level (EQ-5D-5L)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The EQ-5D-5L is a general health status measure comprising a descriptive system and the EQ VAS. The descriptive system comprises 5 dimensions: Mobility, Self-care, Usual activities, Pain/discomfort and Anxiety/depression. Patients are asked to rate their current health and functional status on a 5-point verbal rating scale for each of the 5 domains. Responses are converted into an overall quality of life score via a preference-based statistical mapping algorithm. The scores on these 5 dimensions can be presented as a health profile or can be converted to a single summary index number (utility) reflecting preferability compared to other health profiles. Additionally, patients are asked to indicate how they rate their current overall health on a visual analog scale (EQ-VAS) ranges from 100 for best imaginable health state to 0 for worst imaginable health state.
  • Misura: Work Productivity and Activity Impairment - Lupus (WPAI:lupus)
  • Tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
  • Descrizione: The WPAI:Lupus is an SLE-specific, self-administered questionnaire, that assesses the impact of disease on productivity. The WPAI:Lupus consists of 6 items and has a recall period of the past 7 days. The WPAI:Lupus is divided into 4 domains: Absenteeism (work time missed), Presenteeism (VAS [scored from 0 to 10] rating of impairment while working), Working Productivity Loss (overall work impairment/absenteeism plus presenteeism), and Activity Impairment (VAS [scored from 0 to 10] rating of daily activity, other than work at a job). Scores for each domain are expressed as impairment percentages, with higher scores indicating greater productivity impairment.
