Gastroenterology

This week, clinicians gathered in San Antonio, Texas, for the American College of Gastroenterology (ACG)’s 2019 meeting, where a number of presentations focused on the treatment of inflammatory bowel disease. During the congress, 2 studies presented addressed adverse events (AEs) associated with—one of which was resolved by—the use of biosimilar infliximab, CT-P13 (Inflectra).
The Canadian Association of Gastroenterology and Crohn’s and Colitis Canada this week announced a joint statement on biosimilars in the treatment of inflammatory bowel disease (IBD). The paper, which is slated to appear in the Journal of the Canadian Association of Gastroenterology, recommends that patients stable on biologic treatment should not be subject to nonmedical switching, and recommends against automatic substitution of biosimilars for their references.
During the United European Gastroenterology Week 2019, held October 29-23 in Barcelona, Spain, researchers from Celltrion presented pooled data from 3 postmarketing studies of CT-P13 in patients with inflammatory bowel disease (IBD) that underscore the safety of the biosimilar.
While providers are increasingly comfortable with switching patients with inflammatory bowel disease (IBD) from reference biologics to biosimilars on the basis of a wealth of reassuring data on the safety and efficacy of such transitions, there are fewer data available about switching among multiple biosimilars of the same reference.
Therapeutic drug monitoring is of particular importance in optimizing treatment for patients with inflammatory bowel disease (IBD) who are receiving therapy with anti–tumor necrosis (anti-TNF) drugs like adalimumab. This week, during the United European Gastroenterology (UEG) Week 2019 meeting, held in Barcelona, Spain, researchers will present new findings on monitoring serum trough levels of Samsung Bioepis’ biosimilar adalimumab, Imraldi, in patients with IBD.
During the United European Gastroenterology Week 2019 meeting, held in Barcelona, Spain, researchers presented results of a phase 1 pivotal study of a subcutaneously administered formulation of biosimilar infliximab, CT-P13 (Remsima, Inflectra), in patients with inflammatory bowel disease (IBD).
A pair of studies appearing in The New England Journal of Medicine report on 2 separate studies of biologics in patients with moderate-to-severe ulcerative colitis: One study confirms top-line results seen earlier this year in a head-to-head study of vedolizumab and adalimumab, and the other reports on the results of a single intravenous infusion of ustekinumab followed by subcutaneous maintenance injections.
While acknowledging the role that the Orphan Drug Act had in incentivizing drug companies to develop treatments for small populations suffering from rare diseases, America’s Health Insurance Plans (AHIP) says pharmaceutical companies are using orphan drug status to create blockbuster drugs that are then used to treat other common medical conditions.
The Institute for Clinical and Economic Review (ICER) said this week it will review the comparative clinical effectiveness and value of therapies for ulcerative colitis, including the reference infliximab product from Johnson & Johnson and biosimilar infliximab from Pfizer.
A paper published in Pharmaceutics describes development and validation of a production process for 5 mg tablets of infliximab, using biosimilar CT-P13 (Remsima, Inflectra), for the treatment of inflammatory bowel disease.
