A First-in-Human Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of RO7507062 in Participants With Systemic Lupus Erythematosus
Study Details
Study Description
Brief Summary
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.
Condition or Disease | Intervention/Treatment | Phase |
---|---|---|
Phase 1 |
Detailed Description
Tocilizumab is an additional investigational medicinal product (IMP), which will be used when required in case of clinical presentation of cytokine release syndrome (CRS). Data on the efficacy of tocilizumab in ameliorating the symptoms of CRS related to RO7507062 will be collected in this study.

Outcome Measures
Primary Outcome Measures

- Area Under the Serum Concentration Versus Time Curve Extrapolated to Infinity (AUCinf) of RO7507062 [Up to approximately 12 months]
- Area Under the Plasma Concentration Versus Time Curve From Zero to the Last Measurable Concentration (AUClast) of RO7507062 [Up to approximately 12 months]
- Apparent Terminal Half-Life (T1/2) of RO7507062 [Up to approximately 12 months]
- Terminal Rate Constant (λz) of RO7507062 [Up to approximately 12 months]
- Apparent Volume of Distribution (Vz/F) of RO7507062 [Up to approximately 12 months]
