The authors concluded that in their analysis of real-world data, the effectiveness of the biosimilar was equivalent to that of the reference product in patients with Crohn disease (CD) who were naïve to therapy with infliximab, and no difference was observed in terms of safety between the 2 therapies.
A recent study sought to clarify factors that could predict therapeutic response to infliximab in Japanese patients with Crohn disease (CD), and found 4 key indicators that may predict response in clinical practice.
Results of a recent survey demonstrate that Asian physicians are less confident in using biosimilars than their European peers are. 
In many regulatory territories, patients with Crohn disease (CD) who lose response to adalimumab at a dose of 40 mg given every other week may be given an escalation to 40 mg every week. However, in Japan, where adalimumab is typically administered by a healthcare provider rather than by the patient, a study investigated the efficacy, safety, and pharmacokinetics (PK) of adalimumab after a dose escalation to 80 mg every other week as a means to reduce the need for additional patient appointments.
During the 83rd Annual Scientific Meeting of the American College of Gastroenterology, researchers from the United Kingdom reported on yet another large, nonmedical switch from reference infliximab to biosimilar CT-P13 (Inflectra, Remsima), this time in the Pennine Acute Hospitals Trust. 
Results of a small Greek observational study suggest that biosimilar infliximab may be an effective alternative for the treatment of patients with inflammatory bowel disease (IBD) who have active disease and experienced a loss of response to innovator infliximab (Remicade). 
When treating any disease, adherence is key. Specifically, however, in inflammatory bowel disease (IBD), adhering to biologic therapy is critical in the management of these diseases, as previous research has demonstrated that a medication possession ratio (MPR) of less than 0.86 significantly increases the risk of disease flare.
 
Early-onset inflammatory bowel disease (IBD) can have a more aggressive course than later-onset disease, making prompt treatment for children with IBD especially important. Given the high cost of biologics that treat pediatric IBD—adalimumab and infliximab—biosimilars are emerging as an important cost-saving option that can prevent the premature termination of biologic therapy for financial reasons. 
As more biosimilars make their way to patients in the United States and Europe, stakeholders seek reassurance on switching to these products. A newly published systematic review sought to investigate the safety and efficacy of switching between reference and biosimilar infliximab in patients with inflammatory disorders. 
While real-world data, such as those derived from the NOR-SWITCH study, have been reassuring about the feasibility of switching patients with inflammatory diseases from reference infliximab (Remicade) to biosimilar CT-P13 (sold as Inflectra and Remsima), some ambiguous data in patients with inflammatory bowel disease (IBD) have raised questions among clinicians about switching in the indications of Crohn disease and ulcerative colitis.
