Brief summary

The purpose of this study is to assess the PK, PD, and safety of anifrolumab as SC administration or IV infusion in adult participants with systemic lupus erythematosus (SLE).

Detailed description

This is a multicentre, randomised, phase I open-label study. The study will comprise of the following: * Screening period: Up to 30 days * Two treatment periods * Part A: Randomised SC vs IV Treatment Period: 5 weeks * Part B: Optional Extended Treatment Period: Up to 47 weeks * Safety follow-up period: 12 weeks after the final dose Part A will include all participants who will be randomised into SC anifrolumab via autoinjector (AI) or IV anifrolumab. Part B is an optional extended treatment period where participants will receive SC anifrolumab via accessorised prefilled syringe (aPFS).

Interventions
