A Study to Evaluate the Treatment Outcomes of Subcutaneous Anifrolumab in Immunosuppressant-naïve and Biologic-naïve Systemic Lupus Erythematosus
SUNFLOWER
Multinational, Interventional, 52-week, Open-label, Single-arm Study to Evaluate the Treatment Outcomes of Anifrolumab 120 mg Subcutaneous Once Weekly in Immunosuppressant-naïve and Biologic-naïve Systemic Lupus Erythematosus (SUNFLOWER)

Brief Summary
The purpose of the SUNFLOWER study is to describe clinical outcomes, including DORIS remission, achieved following the initiation of anifrolumab 120 mg SC once weekly (QW) as add-on therapy to an anti-malarial, with or without GC; in patients not in LLDAS at enrolment. Patients will be naïve to any prior conventional immunosuppressant including prior biologic therapy at enrolment. The study will also employ a tapering protocol for a systematic approach to GC tapering, seeking to understand better the proportion of patients in remission who can successfully withdraw chronic GC completely.

Outcome Measures
Primary Outcomes (1)
Attainment of DORIS remission
Proportion of participants who are in DORIS remission at Week 52 will be assessed. DORIS remission is defined as Clinical SLEDAI-2K (sum of all SLEDAI-2K items except for increased deoxyribonucleic acid \[DNA\] binding and low complement) = 0; PGA \[0-3\] \< 0.5, prednisone 5 mg/day or less, and stable antimalarials, ISs, and biologics.
At Week 52
Secondary Outcomes (16)
To assess the attainment of low level disease activity
At Week 28 and 52
Time spent in DORIS remission, LLDAS or LLDAS-5
At Week 52
Sustaining DORIS remission, LLDAS or LLDAS-5
All subsequent visits including 52 Week
Sustaining DORIS remission, LLDAS or LLDAS-5
At 3 consecutive visits occurring every 4 weeks during the 52 Week study
Time to attain and sustain DORIS, or LLDAS, or LLDAS-5
Through Week 52
- +11 more secondary outcomes
Study Arms (1)
Anifrolumab
OTHERParticipants will receive dose A of anifrolumab on X dosing schedule beginning on Day 1 for a maximum of 52 -week during the study

You may not qualify if:
- Subjects with history of, or current diagnosis of, a clinically significant non-SLE related vasculitis syndrome.
- Subjects with antiphospholipid antibody syndrome on stable anticoagulant therapy at an effective dose (e.g., if on warfarin, an international normalized ratio \[INR\] target 2 to 3 or as appropriate for the clinical situation) are only allowed if this is not the sole or the predominant feature of their SLE.
- Subjects with a serious thrombotic event (e.g., pulmonary embolism stroke, deep vein thrombosis) or unexplained pregnancy loss within 1 year before the screening visit are excluded.
- Subjects with a history of catastrophic antiphospholipid syndrome or saddle embolism.
- Subjects with a history of 3 or more unexplained consecutive pregnancy losses.

- Active severe or unstable neuropsychiatric SLE including, but not limited to aseptic meningitis, cerebral vasculitis, myelopathy, demyelination syndromes (ascending, transverse, acute inflammatory demyelinating polyradiculopathy), acute confusional state, impaired level of consciousness, psychosis, acute stroke or stroke syndrome, cranial neuropathy, status epilepticus, cerebellar ataxia, lupus headache and mononeuritis multiplex, where, protocol-specified standard therapy is insufficient.
- Active severe SLE-driven renal disease where, protocol-specified standard therapy is insufficient.
- Current diagnosis of, catastrophic antiphospholipid syndrome (APS).
- History of recurrent infection requiring hospitalization and IV antibiotics (e.g., 3 or more of the same type of infection over the previous 52 weeks).
- Known History of a primary immunodeficiency, splenectomy, or any underlying condition that predisposes the participant to infection, or a positive result for HIV at Screening.
