A First-in-Human Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of RO7507062 in Participants With Systemic Lupus Erythematosus

An Open-label, Multicenter, Dose Escalation, First-in-Human Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Subcutaneously Administered RO7507062 in Participants With Systemic Lupus Erythematosus

The purpose of this study is to investigate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of RO7507062 in participants with systemic lupus erythematosus (SLE). The study will have 2 parts: Part 1 is a single ascending dose-finding (SAD) part and Part 2 is a dose escalation with fractionated dosing part.

• For participants receiving oral corticosteroids (OCS), treatment with ≤ 20 milligram per day (mg/day) prednisone or equivalent, during Screening, at a dose that has been stable for at least 7 days prior to Day 1.
• For participants receiving conventional immunosuppressants (e.g., azathioprine, sulfasalazine, mycophenolate mofetil [≤ 3.0 grams per day], mycophenolic acid [≤ 3 grams per day], methotrexate [oral, SC, or intramuscular routes]), and calcineurin inhibitors [oral]), treatment should be at a stable dose for at least 6 weeks prior to Screening and during Screening and expected to remain stable during the study.

Exclusion Criteria:

• Active or unstable lupus-associated neuropsychiatric disease.
• Catastrophic or severe antiphospholipid syndrome within 12 months prior to Screening or during Screening.
• Presence of severe lupus-associated renal disease that is likely to require treatment with cyclophosphamide, B-cell-depleting therapies, other biologic or targeted therapies.
