Fig 1 Study design. Participants recorded the occurrence and severity of their symptoms and use of rescue medications during screening (7 days) and once randomized at months 2, 4, 6, 15, and 18 (14 days) and during the primary periods (months 8-12 and months 20-24). Primary periods were defined from October 1 to December 31 of each study year.

Fig 2 Symptom and rescue medication scores (FASYear1); ARTSS (A), ARMS (B), and ARSS (C). Observations for all variables were available for 136 participants in the 500IR group, 141 participants in the 300IR group, and 153 participants in the placebo group, except for ocular itching (131, 139, and 148 participants, respectively). *P < .05 (analysis of covariance, each of the 2 active groups vs the placebo group).

Fig 3 AAdSS (FASYear1 and FASYear2). Fourteen-day diaries were collected after each time point visit (months 2-10 and months 15-20) or preceding the month 12 and month 24 visits. Mean baseline ARTSSs (no rescue medication allowed) were 7.26 (500IR group), 6.94 (300IR group), and 6.79 (placebo group). *P < .05 (repeated-measures analysis of covariance mixed model, each of the 2 active groups vs the placebo group).

Fig 4 Symptom and rescue medication scores (FASYear2); AAdSS (A), ARTSS (B), ARMS (C) and ARSS (D). Observations for all variables were available for 120 participants in the 500IR group, 132 participants in the 300IR group, and 137 participants in the placebo group, except for ocular itching (117, 131, and 134 participants, respectively). *P < .05 (analysis of covariance, each of the 2 active groups vs the placebo group).

Fig E1 Participants' disposition. Participants were randomized to one of the 3 groups, treated for approximately 12 months, and followed for the subsequent 12-month, immunotherapy-free period. Safety set year 1 was comprised of all participants who received at least 1 dose of investigational product. Safety set year 2 was comprised of all participants who completed year 1.
