Effectiveness, safety, and pharmacokinetics of the infliximab biosimilar CT-P13 after non-medical switch from the infliximab originator in patients with inflammatory bowel disease.

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
BACKGROUND/
aimsThe introduction of anti-tumor necrosis factor-α antibodies transformed the landscape of inflammatory bowel disease (IBD) treatment. Because biologics are associated with increased medical costs, the use of biosimilars (BS) is recommended. However, high-quality evidence on the efficacy of BS in Japan remains limited. Therefore, this study aimed to evaluate the efficacy and safety of BS in patients with IBD.
methodsPatients with IBD who underwent a non-medical switch (NMS) from infliximab originator (IFX-O) to IFX-BS at Fukuoka University Chikushi Hospital were prospectively evaluated. The observation period was up to 56 weeks after the NMS, and the rate of continuation, clinical remission at 56 weeks, safety, and changes in trough concentration were analyzed. Moreover, a questionnaire survey regarding BS and NMS was conducted.
resultsA total of 167 patients were included in this study. The continuation rate for IFX-BS therapy after NMS was high (95.6%). The remission maintenance rate at 56 weeks was 85.7% for patients with Crohn's disease and 77.8% for patients with ulcerative colitis. Adverse events were observed in 22.8% of patients. However, only 2 severe adverse events were recorded. The ratios of trough concentrations at 8, 24, and 56 weeks to that at week 0 were 115.6%, 101.2%, and 123.5%, respectively, indicating statistical non-inferiority. In a questionnaire survey, only 6.2% of the patients were aware of BS, however, more than half of them agreed with the NMS recommendation.
conclusionsThe efficacy and safety of IFX-BS after NMS are high. In addition, its trough concentration is serologically non-inferior to baseline values.
