Conditions: Rheumatoid Arthritis
Allocation: NON_RANDOMIZED | Intervention model: PARALLEL
Enrollment: 91
Healthy volunteers: no

Brief summary:
This study is designed to evaluate RLHFs concerning administration of the tocilizumab autoinjector AI-1000 G2 in adults with rheumatoid arthritis (RA) who have been receiving subcutaneous (SC) tocilizumab using the commercially available prefilled syringe and needle safety device (PFS-NSD). The study will enroll participants with RA, a subset of whom will be assigned to perform self-injection with the AI-1000 G2. Enrolled caregivers (CGs) and healthcare professionals (HCPs) will administer the AI-1000 G2 injection to the remaining study participants.

Detailed description:

Arms:
arm 1: CGs will perform injection of SC tocilizumab to a subset of participants with RA using the AI-1000 G2 device. Visit 1 (Day 0) will be conducted for administration training, while Visits 2 and 3 (Days 14 and 28) will be conducted for use/performance evaluation. arm 2: HCPs will perform injection of SC tocilizumab to a subset of participants with RA using the AI-1000 G2 device. Because enrolled HCPs are to be professionally qualified to deliver SC injections, no administration training will be provided. Visits 2 and 3 (Days 14 and 28) will be conducted for use/performance evaluation. arm 3: Participants with RA will perform self-injection of SC tocilizumab with the AI-1000 G2 device. Visit 1 (Day 0) will be conducted for administration training, while Visits 2 and 3 (Days 14 and 28) will be conducted for use/performance evaluation. arm 4: CGs will perform injection of SC tocilizumab to participants with RA using the AI-1000 G2 device. Visit 1 (Day 0) will be conducted for administration training, while Visits 2 and 3 (Days 14 and 28) will be conducted for use/performance evaluation. arm 5: HCPs will perform injection of SC tocilizumab to participants with RA using the AI-1000 G2 device. Because enrolled HCPs are to be professionally qualified to deliver SC injections, no administration training will be provided. Visit 1 (Day 0) will be performed by the study nurse. Visits 2 and 3 (Days 14 and 28) will be conducted by the HCP for use/performance evaluation.

Interventions: intervention 1: AI-1000 G2 intervention 2: Tocilizumab
Intervention descriptions: intervention 1: Tocilizumab will be administered using the AI-1000 G2. intervention 2: Participants will receive three doses of SC tocilizumab using the AI-1000 G2 device at Visits 1, 2, and 3 (Days 0, 14, and 28). The dose will remain at 162 milligrams (mg) unless changes are required per protocol for safety or efficacy reasons.
