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.

Celltrion presented new research that demonstrates that a formulation of its infliximab biosimilar intended for subcutaneous administration is comparable to the intravenously administered option. The phase 1 study compared the subcutaneous formulation—which can be self-administered—with the FDA-approved intravenous formulation in patients with active Crohn disease (CD).

Research published in conjunction with the 2018 American Society of Clinical Oncology Annual Meeting presented new findings on the use granulocyte-colony stimulating factor agents in treating febrile neutropenia (FN) and in peripheral stem cell mobilization.

On June 1, drug maker Apotex announced that its Apobiologix division has received approval from Health Canada for its pegfilgrastim biosimilar, Lapelga. Lapelga is the first pegfilgrastim biosimilar to be approved in a highly regulated territory.

During the 2018 American Society of Clinical Oncology's Annual Meeting, researchers presented findings on 3 biosimilar trastuzumab products: Samsung Bioepis’ SB3, Agmen’s ABP 980, and Biocad’s Herticad.

This week, the FDA approved an expanded indication of the Janus kinase (JAK) inhibitor tofacitinib (Xeljanz) to include adults with moderate to severe ulcerative colitis. Tofacitinib is the first oral medicine approved for long-term use in UC, and provides an alternative to anti–tumor necrosis factor (anti-TNF) drugs that must be injected or infused.

Boehringer Ingelheim’s (BI) adalimumab biosimilar, Cyltezo, can be successfully self-administered—via auto-injector—by most patients with rheumatoid arthritis (RA).

In a new paper, researchers sought to describe how much the European Union is overspending on neovascular age-related macular degeneration treatment by relying on ranibizumab and aflibercept rather than bevacizumab in ophthalmology.

While it is already known that obesity may contribute to an increased risk developing some immune-mediated inflammatory diseases, as well as more severe disease activity and a higher burden of hospitalization, a new review found that obesity is also a predictor of inferior response to anti–tumor necrosis factor (anti-TNF) agents.

The authors of a recent study report that the addition of a disease-modifying anti-rheumatic drug (DMARD) or a switch to ustekinumab showed greater efficacy than changing anti–tumor necrosis factor (anti-TNF) treatments in patients with inflammatory bowel disease (IBD) who develop paradoxical arthritis.

This week, Drugs published a letter to the editor concerning a systematic literature review that showed a low risk of safety concerns or loss of efficacy after switching from a reference biologic product to a biosimilar. The letter’s authors said that switching is a beneficial topic for exploration but criticized the review for “over-interpretation of the available data.”

Currently, beyond the evaluation of a patient’s 28-joint disease activity score (DAS28), there are no standard methods to determine whether patients will respond well to dose reduction of anti–tumor necrosis factor therapy.

One of the main concerns attributed to anti–tumor necrosis factor (anti-TNF) treatment during pregnancy is the ability for the therapy to be transferred to the fetus. Complete immunoglobulin G (IgG) antibodies, both maternal and therapeutic, are delivered to the placenta during pregnancy naturally. This fact is important for patients who are treated with adalimumab, golimumab, and infliximab, which are complete IgG1 anti-TNF antibodies, and therefore transferred easily to the placenta.

Researchers involved in the Persephone phase 3 randomized clinical trial of 4089 women with HER2-positive early breast cancer found that 6 months of trastuzumab treatment was not inferior to the current standard.

Although the benefits of originator infliximab have been deemed to outweigh the potential harm during pregnancy, in a recent observational study, researchers looked to evaluate whether biosimilar infliximab therapy was associated with any new safety risks.

At the 58th Annual Scientific Meeting of the British Society for Haematology, held from April 16-18, 2018, in Liverpool, United Kingdom, researchers from 2 hospitals reported on the use of biosimilar rituximab in real-world settings.

In an effort to accurately predict an individual patient’s response after starting or tapering an anti–tumor necrosis factor (anti-TNF) agent, researchers from the Netherlands, reporting findings in Rheumatic and Musculoskeletal Diseases, explain that calprotectin has some predictive value for clinical response in patients starting anti-TNF treatment, although it was not predictive of clinical response after tapering.
