Infliximab and its biosimilars are often used as a treatment for ulcerative colitis (UC), and recent years have seen the collection of real-world data on the use of biosimilar CT-P13 (Inflectra, Remsima) that confirm the product’s equivalent efficacy to that of the reference, Remicade. One newly published study, which assessed patient data from a French nationwide health administrative database, found that not only is biosimilar CT-P13 as effective as the reference product in treating UC, it may also have a lower risk of serious infections.

All children with inflammatory bowel disease (IBD) who were receiving maintenance infliximab at a single center between 2017 and 2018 were included in the study.

During Digestive Disease Week 2019, held May 18-21 in San Diego, California, researchers presented the 1-year results of a phase 1 trial of subcutaneous CT-P13 versus the intravenous formulation of the biosimilar in patients with Crohn disease (CD).

Research presented at this week’s ISPOR 2019 meeting sheds important light on the impact of biologics on the use of other healthcare resources.

Access to therapy for ulcerative colitis (UC) and Crohn disease (CD) may not be consistent with treatment guidelines because of payer policies that do not concur with the American Gastroenterological Association clinical pathways for the treatment of inflammatory bowel disease.

A new consensus report calls the nocebo effect underrecognized in the area of biosimilars and says that more research is needed on this important topic.

Approval of biosimilars in indications for which they were not studied directly in phase 3 clinical trials relies on the extrapolation of indications, a concept that is scientifically justified but, nevertheless, has generated some concerns among clinicians. In the case of biosimilar infliximab CT-P13 (Inflectra, Remsima), some gastroenterologists have voiced a lack of confidence in the biosimilar for the treatment of inflammatory bowel disease, including Crohn disease (CD) and ulcerative colitis. Now, head-to-head study, published in The Lancet, has produced data that may help allay those worries.

Patient access to treatment has improved in many countries since the advent of biosimilars, where access to biologic treatments is variable among nations and faces restrictions based on limitations to healthcare resources. During the Medicines for Europe 17th Biosimilar Medicines Conference, held March 28-29 in Amsterdam, the Netherlands, a panel of healthcare providers discussed this expanded access as well as other benefits that accrue to patients when biosimilars generate competition in the biologics market. They also considered lingering hurdles with provider education.

During this week’s 14th Congress of the European Crohn’s and Colitis Organisation, multiple research teams reported on efforts to better understand the factors that impact adalimumab therapy in patients with inflammatory bowel disease (IBD).

Celltrion, maker of biosimilar infliximab CT-P13 (Remsima, Inflectra), has recently submitted an application to the European Medicines Agency for a subcutaneous formulation of the biosimilar.
