Study Description

Brief Summary:

This study will be conducted to compare the pharmacokinetic (PK) exposure after a single SC dose of anifrolumab administered using an AI with the PK exposure after a single subcutaneous (SC) dose of anifrolumab administered using APFS in healthy male and female volunteers.

Condition or disease	Intervention/treatment	Phase
Healthy Participants Study	Drug: Anifrolumab; Device: Autoinjector; Device: Accessorized Pre-Filled Syringe	Phase 1

Detailed Description:

This will be a multicenter, randomized, open-label, parallel group Phase 1 study.

After meeting the eligibility criteria, all eligible participants will be randomized 1:1:1:1:1:1 to a device group (APFS or AI) for an anatomical injection site as defined in the protocol. Randomization will be stratified by protocol defined body weight categories and clinical unit.

The study will comprise:

• A Screening Period up to 28 days.
• One treatment period during which eligible participants will be admitted to the Clinical Unit on Day -1 to reassess their eligibility. Participants who meet eligibility criteria will be randomized to receive a single subcutaneous (SC) dose of anifrolumab by either APFS or AI device on Day 1. Participants will be discharged on Day 3.
• The participants will return to the center for Follow-up Visits on Days 6, 8, 12, 15, 22, 29, and 43.
• A final Follow-up Visit on Day 57.

5. Apparent volume of distribution following extravascular administration (based on terminal phase) (Vz/F) [ Time Frame: Day 1 to Day 57 ]
   Evaluation of the Vz/F of anifrolumab administered to various anatomical injection sites and in healthy participants within different body weight ranges will be done.
6. Time of last quantifiable concentration (tlast) [ Time Frame: Day 1 to Day 57 ]
   Evaluation of the tlast of anifrolumab administered to various anatomical injection sites and in healthy participants within different body weight ranges will be done.
7. Number of participants with positive Anti-drug antibodies (ADA) [ Time Frame: Day 1, 29 and 57 ]
   Evaluation of the immunogenicity of anifrolumab delivered by AI or APFS will be done.
