Inclusion criteria
. Estimated glomerular filtration rate (eGFR) \>30 milliliters/minute/1.73 square meters (mL/min/1.73 m\^2) at the screening visit.
. Participant has a confirmed diagnosis of SLE according to European League Against Rheumatism/American College of Rheumatology SLE classification criteria ≥ 24 weeks prior to signing the informed consent form (ICF).
. Current scalp involvement between 25% and 95%, inclusive (Severity of Alopecia Tool \[SALT\] score between 25 and 95, inclusive), at screening.
. Current episode of AA is of duration \> 24 weeks (without evidence of spontaneous terminal hair regrowth at the time of screening and first treatment, i.e., no more than 10% regrowth), but ≤ 5 years from onset of current episode of severe scalp hair loss.
. Prior biopsy (no time limit) showing histologic minimal change disease (MCD), FSGS, or MCD/FSGS spectrum.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. History of at least one prior episode of nephrotic syndrome, defined as 24-hour urine protein \> 3.5 grams per day (g/day) and serum albumin \< 3.5 grams per deciliter (g/dL).
. History of steroid responsive nephrotic syndrome, including participants who achieved complete remission, partial remission, had a course of steroid dependent nephrotic syndrome or relapsing nephrotic syndrome (all defined as per the managing physician at the time of the episode).
Exclusion criteria
. Receipt of high-dose corticosteroid therapy within 4 weeks prior to screening as either (a) intravenous (IV) pulse corticosteroid therapy or (b) daily oral corticosteroid therapy of ≥ 1 milligrams per kilogram (mg/kg) or up to 40 milligrams per day (mg/day) prednisone (or equivalent).
. Receipt of blood products within 6 months prior to screening.
. Previous exposure to VIS171 or any other drug targeting interleukins (IL)-2 or the IL-2 receptor or T regulatory cells.
. History of or current diagnosis of catastrophic or severe anti-phospholipid syndrome (APS) within 1 year prior to signing ICF. SLE participants with APS adequately controlled by anticoagulant are eligible. SLE participants who are found to be triple positive for anti-phospholipid antibodies at screening (without clinical APS) will be excluded unless they are on stable anti-thrombotic therapy.
. Known primary immunodeficiency disorder.
. Participant has a history of Class V lupus nephritis.
. Receipt of anifrolumab, tumor necrosis factor-alpha monoclonal antibodies (\[TNF\]-α mAb), immunoglobulins (IV/SC) plasmapheresis, or any other immunosuppressants (calcineurin inhibitors, Janus kinase \[JAK\] inhibitors or other kinase inhibitors), other than hydroxychloroquine, mycophenolic acid (MPA)/mycophenolate mofetil (MMF) and corticosteroids, within 6 months prior to screening.
. Participant has concomitant hair loss of another form, including but not limited to traction alopecia, central centrifugal cicatricial alopecia, lichen planopilaris, frontal fibrosing alopecia, or androgenetic alopecia.
