Transitioning from reference adalimumab (Humira) to Amgen’s FDA- and EU-approved adalimumab biosimilar ABP 501 (Amgevita) was not associated with increased immunogenicity over an observation period of 72 weeks in patients with rheumatoid arthritis, according to the results of a study presented at the European Congress of Rheumatology.

Italian researchers report that 72% of their trial participants being treated for psoriatic arthritis achieved sustained remission with ETN 25 mg biweekly, which was maintained a year after treatment initiation.

A survey of German patients who used a prefilled pen for subcutaneous delivery of biosimilar etanercept SB4 has reported a very high level of patient satisfaction with the product following an interim analysis.

In the short term, nonmedical switching (NMS) of stable patients with a rheumatic condition from originator biologics to biosimilars could have “considerable” short-term costs for a rheumatology medical center, according to a study presented at the annual European Congress of Rheumatology.

Intravenous administration of the anti–vascular endothelial growth factor treatment bevacizumab at high doses can result in serious, systemic adverse events (AEs). Additionally, tumors can become resistant to therapy and adopt a more invasive growth pattern. Thus, delivering bevacizumab for the treatment of cancer at a lower dose in a manner that avoids systemic AEs is necessary.

Eales disease (ED) is a common, idiopathic, inflammatory retinal vasculitis that particularly affects young adults. Current treatments available for ED include corticosteroids, laser photocoagulation, retinal cryotherapy, and surgery, but a recent study found that using intravitreal bevacizumab injections may produce better outcomes and reduce the need for surgery.

This month saw a variety of developments in the world of biosimilar drugs for the treatment of rheumatic diseases.

While managing costs is extremely important to physicians and their patients, achieving and maintaining disease control without increasing the risk of complications or toxicities must remain the primary goal in the treatment of chronic inflammatory diseases.

Here are the top 5 biosimilars articles for the week of June 25.

Intestinal Behçet disease (BD), which is an immune-mediated, chronic, inflammatory intestinal disease, can be difficult to treat, in part because the pathogenesis of intestinal BD is unclear. However, as data for using anti–tumor necrosis factor (anti-TNF) drugs have been accumulating in the treatment of inflammatory bowel disease (IBD), which has a similar clinical presentation, the potential to treat BD with these agents is under investigation.

New International League of Associations for Rheumatology (ILAR) recommendations are now available for the treatment of patients with psoriatic arthritis living in resource-poor regions, including Central and South America and Africa.

During the fourth congress of the European Academy of Neurology, held in Lisbon, Portugal, from June 16 to 19, researchers presented on the roles of both existing and investigational anti-CD20 drugs in treating neurological diseases.

Anti–tumor necrosis factor (TNF) agents, widely used in rheumatology and gastroenterology, carry some safety risks. While the risk of infection or malignancy are common concerns, neurological complications, while rare, are also possible.

A new study, published in Alimentary Pharmacology and Therapeutics, sought to test antigenic comparability between the reference infliximab and the biosimilar.

Researchers from Spain, where biosimilar use is encouraged as a way to save on costs and expand access to biologic therapies, recently reported on a multicenter prospective observational study in patients with inflammatory bowel disease (IBD) who switched from reference infliximab to a biosimilar, CT-P13 (Inflectra, Remsima).

Rituximab has previously been shown to be effective at doses of 1000 mg in treating patients with rheumatoid arthritis (RA) who had previously received other biologic agents. Research presented at the European League Against Rheumatism's Annual European Congress of Rheumatology demonstrates that using lower doses of biosimilar rituximab—which may provide a substantial cost savings—is also effective.

At the European League Against Rheumatism Annual European Congress of Rheumatology, researchers presented findings on 3 studies in which patients switched to a biosimilar etanercept molecule from the reference Enbrel.

This week, the American College of Rheumatology (ACR) released a new position statement on the importance of pharmacovigilance and the critical need to continue monitoring new drugs after they reach the market.

The Center for Biosimilars® recaps the top 5 articles for the week of June 11, 2018.

At the European League Against Rheumatism (EULAR)'s Annual European Congress of Rheumatology, held from June 13-16 in Amsterdam, Netherlands, researchers reported on Biocad’s Russian-authorized biosimilar infliximab, BCD-055, and on switches to the widely approved infliximab biosimilar CT-P13 (Inflectra, Remsima).

If European League Against Rheumatism guidelines are followed, when a patient with rheumatoid arthritis (RA) does not reach remission or a state of low disease activity after 6 months of treatment, then the patient’s treatment should be modified regardless of the drug therapy being used (biologic or small molecule).

“I see no reason as a healthcare provider to intentionally go back and forth needlessly, but I see no concerns that, if I do that, bad things would happen,” said Jason Schairer, MD.

Crohn disease (CD) can involve physical, psychological, and social impairments that negatively impact patients’ quality of life, and high levels of anxiety and depression have been observed in patients with CD.

The FDA has approved Genentech’s innovator rituximab (Rituxan) for the treatment of adults with moderate to severe pemphigus vulgaris (PV). This expanded indication makes the drug the first biologic approved for the treatment of PV, a rare autoimmune disease that affects the skin and mucous membranes with progressive blistering.

During a session at the 2018 American Society of Clinical Oncology Annual Meeting, held June 1-5 in Chicago, Illinois, researchers gave a glimpse into new directions in oncology biosimilars through providing results on several studies testing the safety, efficacy, and usage of different biosimilars.

The question of whether to switch patients from a reference biologic to an available biosimilar has been the subject of extensive debate, especially in patients with inflammatory bowel disease (IBD), an indication in which evidence on relevant clinical outcomes after switching is limited.

During the 2018 American Society of Clinical Oncology Annual Meeting, researchers published new findings on the use of rituximab in mantle cell lymphoma (MCL) as well as the outcomes of patients who relapse early after treatment with rituximab for diffuse large B-cell lymphoma (DLBCL).

Clinical practice guidelines recommend the use of granulocyte-colony stimulating factor (G-CSF) therapies, including the long-acting pegfilgrastim (Neulasta), for the prevention of febrile neutropenia in patients receiving myelosuppressive chemotherapy. Real-world data, published in an abstract concurrent with the 2018 American Society of Clinical Oncology Annual Meeting, demonstrate the feasibility of administering pegfilgrastim via an on-body device.
