Who may not be able to join:
- People experiencing a sudden, severe flare of their autoimmune condition just before or during the screening period that needs immediate treatment or is likely to require medications not permitted in the study.
- People with known significant allergies or sensitivities to humanised monoclonal antibodies (a type of laboratory-made protein) or to any ingredients in the study drug.
- People with a history of severe drug allergies, intolerance to topical steroid creams, or serious skin reactions to medications (such as toxic epidermal necrolysis or exfoliative dermatitis).
- People with significant unstable or uncontrolled ongoing health conditions unrelated to their autoimmune disease — such as heart, lung, blood, digestive, liver, kidney, or infection-related conditions — or a planned surgery that the study doctor believes could affect the results or pose an unacceptable risk.
- People with other abnormal lab results that the study doctor believes could significantly affect how the body processes the study drug or interfere with interpreting the study results.
- People with a diagnosis of a primary or acquired immune deficiency condition, except for selective IgA deficiency.
- People with an active infection within 2 weeks before the first dose, or who are currently receiving systemic antibiotic, antiviral, or antifungal treatment (topical treatments for fungal nail infections are permitted).
- People with a history of significant recurring or chronic infections (minor localised infections may be acceptable — confirm with trial site).
- People who have had an opportunistic infection (a serious infection that occurs when the immune system is weakened) within the past 3 years (note: uncomplicated shingles, localised cold sores, and oral thrush are not counted for this purpose).
- People who have had shingles within 3 months before screening.
- People who were hospitalised or required injected antibiotics for a serious infection, if the last dose of antibiotics or hospital discharge was within 30 days of the first study dose.
- People with a history of a serious infection linked to low levels of immunoglobulins (proteins that help fight infection) in the blood.
- People with evidence of active or latent tuberculosis (TB), based on medical history, physical examination, chest X-ray, or a positive TB blood test.
- People who have had confirmed progressive multifocal leukoencephalopathy (a serious brain infection) within the past 12 months, or who have unexplained or worsening neurological symptoms.
- People with a confirmed diagnosis of, or positive test for, HIV at screening.
- People with a significant history of neurological or psychiatric conditions, including epilepsy, dementia, major depression that could interfere with the study, increased suicide risk as assessed by the study doctor, or a history of bleeding in the brain.

- People who have had a bone marrow or solid organ transplant.
- People who have received a live or live-attenuated vaccine within 30 days before screening, or who plan to receive one during the study.
- People who have received certain medications within specific time periods before the first study dose, including (but not limited to):
- Injected corticosteroids (steroids given into a vein or muscle) within 5 weeks
- Certain immune-targeting therapies such as CAR-T cell treatment (at any time), B-cell depleting agents within 4 months, belimumab or anifrolumab within 8 weeks, cyclophosphamide within 12 weeks, certain biologic medicines within 4–8 weeks, certain small molecule inhibitors (such as JAK inhibitors or TYK2 inhibitors) within 4 weeks, intravenous immunoglobulin within 8 weeks, or plasmapheresis within 8 weeks (confirm specific medication timelines with trial site)
- People who are currently enrolled in, or have recently participated in, another clinical trial involving an investigational treatment within 3 months or 5 half-lives of that drug before the first study dose (whichever is longer).
- People who cannot take the preventive or rescue medications used to manage potential side effects of the study drug (such as steroids, antihistamines, fever-reducing medications, or tocilizumab).
- People with a current or recent history (within 12 months) of drug or alcohol dependence or abuse.
- People with certain abnormal liver-related blood test results above specified thresholds (confirm with trial site).
- People with a current or long-term history of liver disease or known liver or bile duct abnormalities (except for Gilbert's syndrome or asymptomatic gallstones).
- People who test positive for hepatitis B at screening or within 3 months before the first dose.
- People who test positive for hepatitis C antibodies or hepatitis C RNA at screening or within 3 months before the first dose, unless a follow-up test confirms the infection has fully resolved.
- People with a prolonged heart rhythm measurement (QTc interval) on an ECG above the specified threshold, as determined by the study doctor (confirm with trial site).
