Percentage of SYDNEY-Associated Product Technical Complaints (PTCs) (Overall) at the Unsupervised Injections: Single-Arm PeriodFrom Week 4 up to Week 12

SYDNEY-associated PTC was defined as any complaint reported on the participant complaint form that triggered an investigation by the device department and was categorized as either device-related, participant-related, or undetermined whether or not associated with an adverse event (AE). Overall category included total of all 3 types of PTCs. The percentage of SYDNEY-associated PTCs was calculated as: Number of PTCs / Number of unsupervised injections\*100. The confidence interval (CI) was calculated using the Wilson score method.

Patient Perspective Questionnaire After the Last Injection (at Week 12): Single-Arm PeriodAt Week 12

The aim of the patient perspective questionnaire (completed by the participant after the last injection) was to generate data to support an understanding of the participant experience and satisfaction associated with use of the large volume SYDNEY to administer the 300 mg dose. The questionnaire consisted of 6 questions about level of satisfaction with various aspects of the SYDNEY; with response to each question ranging from 1 (very dissatisfied) to 10 (very satisfied), with higher scores indicated more satisfaction. An additional question (confidence that Sydney device was used correctly) regarding confidence of use of SYDNEY device in the study was evaluated on a scale of 10; where 1 being not at all confident, to 10 being very confident, higher scores indicated more confidence.
