METHODS: Adults with active NIIPPU received adalimumab in this prospective, observational study (06/2017-04/2020). Patients were evaluated at baseline (V0) and four follow-up visits over 12 months (V1-V4).

PRIMARY ENDPOINT: proportion of patients achieving quiescence (anterior chamber (AC) cells grade and vitreous haze (VH) grade≤0.5+ in both eyes, no new active chorioretinal lesions) at any follow-up visit. Secondary endpoints: proportion of patients achieving quiescence at each visit; proportion of patients maintaining response; and proportion of patients with flares. Workability, visual function, healthcare resource utilisation, and safety were evaluated.

RESULTS: Full analysis set included 149 patients. Quiescence at any follow-up visit was achieved by 129/141 (91%) patients. Quiescence at individual visits was achieved by 99/145 (68%), 110/142 (77%), 102/131 (78%), and 99/128 (77%) patients at V1-V4, respectively. Number of patients in corticosteroid-free quiescence increased from 51/147 (35%; V1) to 67/128 (52%; V4; p<0.05). Proportion of patients with maintained response increased from 89/141 (63%; V2) to 92/121 (76%; V4; p<0.05) and proportion of patients with flare decreased from 25/145 (17%; V1) to 13/128 (10%; V4; p=0.092). Workability and visual function improved throughout the study. Proportion of patients with medical visits for uveitis decreased from 132/149 (89%; V0) to 27/127 (21%; V4). No new safety signals were observed.
