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.

METHODS: Following a systematic literature review, drug survival at 12 and 12-24 months of followup was estimated by summing proportions of patients continuing treatment and dividing by number of studies. Drug survival at ≥ 36 months of followup was estimated through Metaprop.

RESULTS: There were 170 publications included. In the first-line setting, drug survival at 12 months with ETN, IFX, or ADA was 71%, 69%, and 70%, respectively, while at 12-24 months the corresponding rates were 63%, 57%, and 59%. In the second-line setting, drug survival at 12 months with ETN, IFX, or ADA was 61%, 69%, and 55%, respectively, while at 12-24 months the corresponding rates were 53%, 39%, and 43%. Drug survival at ≥ 36 months with ETN, IFX, or ADA in the first-line setting was 59% (95% CI 46-72%), 49% (95% CI 43-54%), and 51% (95% CI 41-60%), respectively, while in the second-line setting the corresponding rates were 56% (95% CI 52-61%), 48% (95% CI 40-55%), and 41% (95% CI 36-47%). Discontinuation of ETN, IFX, and ADA at 36 months of followup was 38-48%, 42-62%, and 38-59%, respectively. Data on CZP and GOL were scarce.

MATERIALS AND METHODS: A retrospective review of case notes on adult psoriasis patients treated with biologics in Hospital Sultanah Aminah Johor Bahru Malaysia, between January 2006 and December 2020. Drug survival was analysed using the Kaplan-Meier method.

RESULTS: By December 2020, 100 patients with 154 treatment courses of biologics were included in the study. Male to female ratio was 1:1. The mean age at onset was 31.36 ± 11.72 years. Ustekinumab was the most frequently prescribed biologics (39%), followed by adalimumab (29.2%), secukinumab (14.9%), etanercept (13%), and infliximab (3.2%). Overall median drug survival for biologics was 25 months (interquartile range [IQR]= 12.0-.0). The median drug survival for ustekinumab was 35 months (IQR, 12-93); followed by 25 months (IQR, 12.0-), 18 months (IQR, 7-85), 17 months (IQR, 11-43), and 8 months (IQR, 1-10) for secukinumab, adalimumab, etanercept, and infliximab, respectively. The main reason for drug discontinuation was loss of efficacy (26%), inadequate funding (14.3%), loss to follow-up (10.4%), adverse events (4.5%), and patients' request (1.3%).

Methods: All axSpA patients attending two centres who commenced TNFi between 2002 and 2016 were included. Routinely recorded patient data were reviewed retrospectively. Patients with paired BASDAI at baseline, 3 and/or 6 months were included for analysis. Sub-optimal response was defined as achieving a ≥ 2-point reduction in BASDAI but not BASDAI50, post-treatment BASDAI remaining at ≥4, and in the opinion of the treating physician these patients demonstrated a meaningful clinical response.

Methods: All patients with a physician-verified diagnosis of axSpA attending two specialist centres who fulfilled the eligibility criteria for TNFi were included. Routinely recorded patient data were reviewed retrospectively. Initial TNFi was recorded as the index drug.

Results: Six hundred and fifty-one patients (94% AS) were included; adalimumab (n = 332), etanercept (n = 205), infliximab (n = 51), golimumab (n = 40) and certolizumab pegol (n = 23) were index TNFi. The mean (s.d.) duration from symptom onset to time of diagnosis was 8.6 (8.7) years and mean (s.d.) duration from diagnosis to TNFi initiation was 12.6 (11.5) years. A total of 224 (34.4%) stopped index TNFi, and 105/224 switched to a second TNFi. Median drug survival for index and second TNFi were 10.2 years (95% CI: 8.8, 11.6 years) and 5.5 years (95% CI: 2.7, 8.3 years), respectively (P < 0.05). Survival rates were not influenced by choice of TNFi. HLA-B27 predicted BASDAI50 and/or two or more point reduction within 6 months and long-term drug survival (P < 0.05). Low disease activity was predicted by non-smoking and low baseline BASDAI (P < 0.05).

METHODS: We used the 2003-2013 Taiwanese National Health Insurance Research Database to identify RA patients who started any RA-related medical therapy from 2008 to 2012. Those who initiated etanercept or adalimumab therapy during 2008-2012 were selected as the TNFi group and those who never received biologic disease-modifying anti-rheumatic drug therapy were identified as the comparison group after excluding the patients who had a history of TB or human immunodeficiency virus infection/acquired immune deficiency syndrome. We used propensity score matching (1:6) for age, sex, and the year of the drug index date to re-select the TNFi group and the non-TNFi controls. After adjusting for potential confounders, hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated to examine the 1-year TB risk in the TNFi group compared with the non-TNFi controls. Subgroup analyses according to the year of treatment initiation and specific TNFi therapy were conducted to assess the trend of 1-year TB risk in TNFi users from 2008 to 2012.

RESULTS: This study identified 5,349 TNFi-treated RA patients and 32,064 matched non-TNFi-treated controls. The 1-year incidence rates of TB were 1,513 per 105 years among the TNFi group and 235 per 105 years among the non-TNFi controls (incidence rate ratio, 6.44; 95% CI, 4.69-8.33). After adjusting for age, gender, disease duration, comoridities, history of TB, and concomitant medications, TNFi users had an increased 1-year TB risk (HR, 7.19; 95% CI, 4.18-12.34) compared with the non-TNFi-treated controls. The 1-year TB risk in TNFi users increased from 2008 to 2011 and deceased in 2012 when the Food and Drug Administration in Taiwan announced the Risk Management Plan for patients scheduled to receive TNFi therapy.

METHODS: Data on 1249 patients from the Swiss IBD Cohort Study (SIBDCS) were analyzed. All EIMs were diagnosed by relevant specialists. Response was classified into improvement, stable disease, and clinical worsening based on the physician's interpretation.

RESULTS: Of the 366 patients with at least 1 EIM, 213 (58.2%) were ever treated with an anti-TNF. A total of 299 treatments were started for 355 EIMs. Patients with EIM were significantly more often treated with anti-TNF compared with those without EIM (58.2% versus 21.0%, P < 0.001). Infliximab was the most frequently used drug (63.2%). In more than 71.8%, a clinical response of the underlying EIM to anti-TNF therapy was observed. In 92 patients (43.2%), anti-TNF treatments were started for the purpose of treating EIM rather than IBD. Response rates to anti-TNF were generally good and best for psoriasis, aphthous stomatitis, uveitis, and peripheral arthritis. In 11 patients, 14 EIM occurred under anti-TNF treatment.
