A Treatment Effectiveness Study Among SLE Patients Receiving Anifrolumab in Routine Clinical Practice. (ASTER)

21 settembre 2026 aggiornato da: AstraZeneca

ASTER: Studio con Anifrolumab per l'efficacia del trattamento nel mondo reale Studio multinazionale, osservazionale, post-lancio sull'efficacia tra i pazienti affetti da LES che ricevono Anifrolumab nella pratica clinica di routine

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.

Descrizione dettagliata

ASTER is a multi-country, single-arm, prospective, observational study. The study will be initiated on a country-by country basis following the commercial launch of anifrolumab. ASTER is a cohort study, with 1-year retrospective baseline data and up to 5 years of follow-up data.

The minimum enrolment period is anticipated to be 18 months (± 5 months) per country, but it may be extended, if necessary, to reach the overall study target.

In general, patients will enter the study between the first anifrolumab prescription and infusion (index), with follow-up until death, loss to follow-up, patient discontinuing the study, or end of study period (whichever occurs first). Data collection will continue for all patients including those who have discontinued anifrolumab during the study, unless the patients have withdrawn their consent for participation in the study. Relevant clinical data collection will continue for the entire follow up while patient reported outcome (PRO) data collection will continue only up to the 3-year follow up.

The study will use clinical assessments that are relevant for SLE-treating physicians in routine clinical practice, as well as introduce a specific measure for skin manifestations to affirm the potency of anifrolumab in treating SLE-related skin manifestations.

The eCRFs will be accessed through secure web-based portals and will be used to ensure consistent data collection for each healthcare provider involved in this study.

Electronic data collection will be the only method of data collection in this study.

Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-Fatigue)
Lasso di tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation

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).

From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
Lupus Quality of Life (LupusQoL)
Lasso di tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation

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.

From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
Patient Global Assessment (PtGA)
Lasso di tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation

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).

EuroQol 5-Dimension Health Questionnaire 5 Level (EQ-5D-5L)
Lasso di tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation

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.

From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation
Work Productivity and Activity Impairment - Lupus (WPAI:lupus)
Lasso di tempo: From Baseline (1 year pre-anifrolumab) until follow-up 3 years post-anifrolumab initiation

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.
