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.

The advent of biosimilar adalimumab in the European Union was among the most eagerly awaited events for biosimilar stakeholders in 2018. During this week’s European Crohn’s and Colitis Organisation’s 14th Congress, held in Copenhagen, Denmark, research teams are presenting findings concerning antidrug antibody (ADA) development related to adalimumab and therapeutic drug monitoring (TDM) of one of those adalimumab biosimilars: Amgen’s ABP 501, sold in the European Union as Amgevita.

In patients with ulcerative colitis and Crohn disease, treatment with biologics is often effective, but adverse events or loss of response may lead to discontinuation. Several studies that will be presented at this week’s European Crohn’s and Colitis Organisation’s 14th Congress, held in Copenhagen, Denmark, sought to investigate factors related drug survival and discontinuation of biologic therapies for inflammatory bowel disease (IBD).

This week, the European Crohn’s and Colitis Organisation (ECCO) will hold its 14th Congress in Copenhagen, Denmark. During the meeting, which runs from March 6-9, experts will gather from around the globe to discuss significant medical research into the treatment of inflammatory bowel disease (IBD), and numerous researchers will present findings on real-world switches to biosimilar infliximab CT-P13 (Inflectra, Remsima).

Evidence to support treating inflammatory bowel disease (IBD), a category that includes Crohn disease and ulcerative colitis, with biosimilar infliximab continues to develop, and several new studies highlight the safety and efficacy of long-term treatment with CT-P13 (Inflectra, Remsima).

Acute severe ulcerative colitis (ASUC) can occur in up to 25% of patients with UC. Salvage therapy with infliximab or cyclosporine is standard first-line therapy for patients who do not respond adequately to intravenous corticosteroids, but questions have arisen about the cost-effectiveness of this approach versus early colectomy. A recent study, conducted in a tertiary hospital network in Australia, sought to compare healthcare utilization and costs between patients with ASUC who had early colectomy and those who were treated with infliximab.

Despite the fact that biosimilars have a longer history in the European Union than in the United States, many European patients still lack awareness of these medicines, and data suggest that a lack of awareness may be keeping patients from adhering to their therapies.

The body of evidence demonstrating the safety and efficacy of biosimilar infliximab, CT-P13 (Inflectra, Remsima), is growing, particularly in the extrapolated indication of inflammatory bowel disease (IBD). This month saw the publication of 2 new studies that provided reassuring data on CT-P13, one of which focused on switching pediatric patients with IBD to CT-P13, and the second of which explored switching to the reference infliximab from the biosimilar in adults with IBD.

A recent letter, published in Alimentary Pharmacology and Therapeutics, reported on early findings from an ongoing, 18-month, multicenter, observational prospective study conducted among the cohort of the Sicilian Network for Inflammatory Bowel Disease (IBD). According to the authors of the letter, these are the first data on SB2 in treating IBD.

Data on the risk of tuberculosis (TB) reactivation with infliximab therapy in patients with inflammatory bowel disease (IBD) who are from countries where TB is particularly prevalent, such as India, remains limited. A recent study sought to evaluate the rate of tubercular reactivation with infliximab in a cohort of patients with IBD.

Biologic drugs can effectively treat inflammatory bowel disease (IBD), but the cost of these products can be prohibitive. Biosimilars such as CT-P13 (Remsima, Inflectra), an infliximab biosimilar referencing Remicade, have the potential to drive down treatment costs and enhance access to biologics for the patients who need them.

Vedolizumab is approved by the FDA for the treatment of moderate to severe Crohn disease or ulcerative colitis, both forms of inflammatory bowel disease (IBD), who have had an inadequate response or loss of response to immunomodulators, tumor necrosis factor inhibitors, or corticosteroid therapy.

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.
