Efficacy of biosimilar infliximab CT-P13 among inpatients with severe steroid-refractory colitis.
Review in International journal of colorectal disease, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionIn this study, we evaluate the efficacy and safety of the biosimilar infliximab, CT-P13, in the treatment of inpatients with severe steroid-refractory colitis.
methodsA retrospective cohort study of adult colitis patients (UC or isolated Crohn's colitis) admitted to the University of Chicago inflammatory bowel disease inpatient service between January 2018 and December 2018 for management of severe colitis refractory to IV steroids who received CT-P13 were included in the study. Patients diagnosed with active small bowel Crohn's disease were excluded. CT-P13 was given as a single infusion of 5 to 10 mg/kg. A comprehensive review of their electronic medical records was performed, and demographic, clinical, laboratory, and endoscopic data were extracted. The primary endpoint was colectomy-free survival.
resultsTwenty-one patients with severe steroid-resistant colitis were included. Twelve patients had ulcerative colitis, seven patients had a diagnosis of indeterminate colitis, and two patients had a diagnosis of Crohn's colitis. The median age was 32.2 years. The median disease duration was 4.3 years, and the median follow-up time was 5.9 months. Patients had a median CRP of 23. All patients had moderate to severe disease on endoscopy. Colectomy-free survival was 76% at 3 months and 70% at 6 months. No severe adverse events were reported in this patient cohort.
conclusionA significant proportion of patients with severe colitis failing IV steroids responded to induction therapy with CT-P13. Colectomy-free survival rates were similar to previous randomized trials using originator infliximab as induction therapy in severe steroid-refractory colitis.
