Abstract Background Evidence on the adoption of different pharmacologic strategies in inflammatory bowel disease (IBD) in the real-world setting in Latin America is scarce. Herein, we describe the clinical characteristics and therapeutic strategies of IBD patients (pts) in Argentina. Methods RISE AR (NCT03488030) was a multicentre, non-interventional study with a cross-sectional evaluation and a 3-year retrospective data collection period conducted in Argentina (12/2018-05/2019) to assess the use of IBD treatments. Adult pts (≥18 years old) with a previous diagnosis of moderate-to-severe ulcerative colitis (UC) or Crohn′s disease (CD) based on clinical, endoscopic or imaging criteria at least 6 months prior to enrolment, were included. Results Overall, 101 CD and 145 UC pts were included. Median (range) age (years) at enrolment was 39.5 (18.2–74.0) for CD (51.2% female) and 41.9 (18.0–80.4) for UC (55.2% female); median (range) disease duration (years) was 7.4 (0.6–36.9) for CD and 5 (0.7–33.8) for UC. At enrolment, 51.5% of CD pts had colonic involvement, 32.7% ileocolonic, 8.9% ileal, 1% isolated upper tract and 5.9% had combined L4/other. In UC, 46.2% had extensive colitis, 44.7% left-sided colitis and proctitis 9.1%. 51.6% of CD pts had non-inflammatory behaviour (37.7% stricturing; 13.9% penetrating), and 34% had perianal disease (13.9% as B1p), resulting in a total of 65.5% pts with complicated disease. Only 9.3% of CD (Harvey Bradshaw Index ≥8) and 7.7% of UC (partial Mayo Score ≥5) pts showed moderate-to-severe disease activity at enrolment. In CD, 70.3% of pts were receiving a biologic agent vs. 29.7% of UC pts. Immunosuppressant (IMM) use was similar between groups (CD 39.6%, UC 40.0%); nearly one-third of the pts on a biologic were receiving concomitant IMM (CD 33.8%, UC 34.9%). Aminosalicylates (5-ASA) were used for most UC pts (89.0%) vs. 47.5% of CD pts, mainly in those with L2 disease. 5-ASA monotherapy was prescribed in 32.1% of UC vs. 5.3% of CD pts, but were also used with IMM (UC 25%, CD 11%), biologics (UC 15%, CD 11.6%) or all three therapies combined (UC 6.4%, CD 17.9%). Corticosteroids (CS) were the least prescribed therapy (CD 7.9%, UC 13.8%). IBD treatments ever prescribed during the retrospective period were (CD, UC): biologics: 79.2%, 33.8%; IMM: 65.3%, 58.6%; 5-ASA: 62.4%, 97.9%; CS: 55.4%, 69.7%. Conclusion In this cohort of IBD patients, biologics use was high, especially among CD patients, in line with disease behaviour, and possibly by their increased availability in these reference centres. This study also highlights country-specific clinical features such as the low proportion of CD pts and the high prevalence of colonic involvement in CD.

ObjectivesElectronic health records (EHR) are receiving growing attention from regulators, biopharmaceuticals and payors as a potential source of real-world evidence. However, their suitability for the study of diseases with complex activity measures is unclear. We sought to evaluate the use of EHR data for estimating treatment effectiveness in inflammatory bowel disease (IBD), using tofacitinib as a use case.MethodsRecords from the University of California, San Francisco (6/2012 to 4/2019) were queried to identify tofacitinib-treated IBD patients. Disease activity variables at baseline and follow-up were manually abstracted according to a preregistered protocol. The proportion of patients meeting the endpoints of recent randomised trials in ulcerative colitis (UC) and Crohn’s disease (CD) was assessed.Results86 patients initiated tofacitinib. Baseline characteristics of the real-world and trial cohorts were similar, except for universal failure of tumour necrosis factor inhibitors in the former. 54% (UC) and 62% (CD) of patients had complete capture of disease activity at baseline (month −6 to 0), while only 32% (UC) and 69% (CD) of patients had complete follow-up data (month 2 to 8). Using data imputation, we estimated the proportion achieving the trial primary endpoints as being similar to the published estimates for both UC (16%, p value=0.5) and CD (38%, p-value=0.8).Discussion/ConclusionThis pilot study reproduced trial-based estimates of tofacitinib efficacy despite its use in a different cohort but revealed substantial missingness in routinely collected data. Future work is needed to strengthen EHR data and enable real-world evidence in complex diseases like IBD.

During past years, the increasing knowledge of molecular mechanisms of inflammatory bowel disease (IBD) have led to the development of several targeted biological therapies. This great expansion of available medical options has prompted the need for comparative data between drugs. For years, given that most randomized controlled trials (RCTs) were performed only versus placebo, this demand has clashed with the absence of head-to-head trials comparing two or more treatments. The quality of evidence coming from real-world experience was low overall, so it was extremely difficult to clarify the correct positioning of the biologicals inside the therapeutic algorithms for IBD. Fortunately, times are changing: head-to-head comparative RCTs have been conducted or are ongoing, and the methodological quality of real-world studies is gradually increasing, mainly thanks to a higher rate of application of statistical methods capable of reducing the selection bias, such as the propensity score. In this evolving scenario, the increasing number of comparative RCTs is providing high-quality data for a correct drug positioning in IBD. In parallel, real-world observational studies are supporting the data coming from RCTs, and covering those comparisons not performed in the RCT setting. We believe that there is moderate evidence already available to support clinicians in the correct choice between different biologicals, and data will certainly be more robust in the near future.
