A Study of Subcutaneous Gefurulimab Using Prefilled Syringe Versus Autoinjector in Healthy Adult Participants
brief summary
This study will evaluate the pharmacokinetics (PK), pharmacodynamics (PD), safety, immunogenicity, and device performance of gefurulimab.
detailed description
This is an open-label, randomized, parallel-group study.
The study consists of 2 periods: a Screening Period (up to 70 days), and an Evaluation Period of 92 days.
Separate randomization lists will be produced for each weight stratum (50 to \< 70 kg, 70 to \< 90 kg, and 90 to \< 110 kg) and within each of the three weight strata, participants will be randomized 1:1:1:1:1:1 to one of the six combinations of device (prefilled syringe with needle safety device \[PFS-SD\] or autoinjector \[AI\]) and injection site (abdomen, thigh, or upper arm),
Participants will receive a single dose of 600 mg gefurulimab on Day 1, will be residential at the clinical unit until Day 5, will have visits on Day 8, quaque week (once a week) \[qw\] thereafter until Day 50, and quaque 2 week (once every two weeks) \[q2w\] from Day 50 until Day 92 during the Evaluation Period.
The total study duration is up to 162 days.
