Overview
Brief Summary
This is a multicenter, randomized, open-label, parallel-group study designed to assess healthcare provider and subject/caregiver reported functionality and performance of a single-use accessorized pre-filled syringe (APFS) or autoinjector (AI) with a fixed 210 mg dose of tezepelumab administered subcutaneously in the clinic and in an at-home setting.
Detailed Description
The study will consist of a screening/run-in period of up to 2 weeks and a treatment period of 24 weeks, followed by a post-treatment follow-up period of 12 weeks. During the treatment period, one dose of 210 mg tezepelumab will be administered via a single-use APFS or AI subcutaneously (SC) every 4 weeks (Q4W) starting at Visit 2 (Week 0) until Visit 7 (Week 20). Subjects will be administered tezepelumab at the site during Visits 2 (Week 0), 3 (Week 4), 4 (Week 8) and 7 (Week 20). At-home administration of tezepelumab will occur during Visit 5 (Week 12) and Visit 6 (Week 16). Each device will be assessed separately using descriptive presentations.

Outcomes
Primary Outcomes
Proportions of HCPs and Subjects/Caregivers Who Successfully Administered Tezepelumab in Clinic or at Home by Device Type
Time Frame: Week 0, Week 4, Week 8, Week 12, Week 16, Week 20
Successful administration is defined as an injection completed, based on a used/returned (HCP or subject/caregiver) answer of YES to all 5 questions in the administration questionnaire, and satisfactory in vitro evaluation of returned/evaluated devices.
Secondary Outcomes
- Change From Baseline in Asthma Control Questionnaire-6 (ACQ-6) Score(Baseline (Week 0), Week 4, Week 8, Week 12, Week 16, Week 20 and Week 24)
- Proportions of Used/Returned Devices That Pass Functional Tests and Visual Inspection and Showed no Evidence of Malfunction(Week 0, Week 4, Week 8, Week 12, Week 16, Week 20)
- Serum Trough Concentrations(Baseline (Week 0), Week 4, Week 20 and Week 24 (EOT))
- Proportions of Devices That Have Been Reported as Malfunctioning (Product Complaints)(Week 0, Week 4, Week 8, Week 12, Week 16, Week 20)
- Anti-drug Antibodies (ADA)(Pre-treatment on dosing days until end of follow-up (Week 36) per protocol)
