Study Endpoints
Primary Endpoints
Percentage of participants reporting very acceptable or totally acceptable local reactions
7 days after each injection (injections administered on Day 1 and Day 15)

The analysis is performed using the 21-item perception of injection (PIN) questionnaire which includes 21 items grouped into 4 multi-item domains: 'Acceptance of ISR' scale score (2 items); 'Bother from ISR' scale score (6 items); 'Leg movement' scale score (4 items); 'Sleep' scale score (4 items); and 5 standalone items: pain during injection; anxiety before injection; anxiety after injection; willingness to be injected in the future; and overall satisfaction with mode of administration. Participant responses are scored on a 5-point Likert scale, where 1 represents the least favorable perception of injection and 5 the most favorable, with domain scores calculated as the mean of all items in that domain. "Acceptance of ISR" is reported in this outcome measure for 2 scores: "very acceptable ISR: and "totally acceptable ISR".

Secondary Endpoints
Percentage of participants reporting very acceptable or totally acceptable local reactions at days 43 and 190
At Day 43 (28 days after second injection) and Day 190 (26 weeks after second injection)
Mean injection site reaction scores, over time, post-injection, at days 8 and 22
At Day 8 and Day 22 (7 days after each injection visit)
Median injection site reaction scores, over time, post-injection, at days 8 and 22
At Day 8 and Day 22 (7 days after each injection visit)
