Conditions
Brief summary
The study consists of an eligibility screening period, two study periods involving single doses of tocilizumab (TCZ) according to an open-label, randomized, two-period crossover design with an interval of 6 weeks between periods, and a 6 week follow-up period. Healthy participants will receive a single subcutaneous (SC) injection of TCZ via a pre-filled syringe-needle safety device (PFS-NSD) and a single injection via an autoinjector (AI). The total duration of the study is up to 16 weeks from screening to follow-up. After screening, eligible participants will be randomly assigned to one of the two possible treatment sequences (Sequence 1: AI-1000 G2 followed by PFS-NSD or Sequence 2: PFS-NSD followed by AI-1000 G2) and assigned to one of three injection sites (1: abdomen, 2: thigh, or 3: upper arm). All participant groups will receive a total of two TCZ administrations each.
Interventions
The device will contain TCZ (180 milligrams per milliliter \[mg/mL\]) SC formulation single dose of 0.9 mL that corresponds to 162 mg TCZ administered via PFS and assembled in the AI (AI-1000 G2).
The device will contain TCZ (180 mg/mL) SC formulation single dose of 0.9 mL that corresponds to 162 mg TCZ administered via PFS-NSD.
Participants will receive two single doses of 162 mg tocilizumab SC on Day 1 (Period 1) and Day 43 (Period 2), with a washout period of 6 weeks between the periods.
