Mylan and Biocon have announced that their biosimilar trastuzumab, Ogivri, has become commercially available in the United States. The biosimilar, referencing Herceptin, is now available in a 420-mg multidose vial and a 150-mg single-dose vial.

Nordic countries have had some of the highest rates of biosimilar use, and extensive registry data in these countries also allow for observational studies of biosimilar use in real-world clinical practice. A new study used data from 5 such registries—which included more than 2000 patients with spondyloarthritis—to assess retention rates for those treated with biosimilars or reference products of etanercept and infliximab.

The American Medical Association (AMA) wants medical schools and residency programs to start training medical students and residents in healthcare economics.

Biosimilar infliximab CT-P13 (Inflectra, Remsima) has been the subject of numerous studies since its authorization in multiple regulatory territories, and this month, data from the Korean College of Rheumatology Biologics (KOBIO) registry add to the growing body of knowledge about this biosimilar’s use in patients with rheumatoid arthritis in routine clinical practice.

This week, a study from Spain retrospectively compared direct costs of intravenous and subcutaneous reference rituximab in the setting of lymphoma, taking into consideration drug costs, pharmacy costs, and chair time-related costs at a single center in 2017. They also conducted the same analysis using the costs of biosimilar rituximab.

A recent review explored the evidence of monoclonal antibodies (mAb) and fusion proteins (FP) to examine their safety and efficacy in the most common chronic inflammatory diseases in children—bronchial asthma, psoriasis, juvenile idiopathic arthritis (JIA), and chronic inflammatory bowel diseases (IBD).

The field of biosimilar contenders for anti–vascular endothelial growth factor (anti-VEGF) therapies is taking shape, with biosimilar developer Coherus seeking to launch its ranibizumab biosimilar in 2021 and Samsung Bioepis having reached a commercialization agreement for 2 biosimilar anti-VEGFs of its own. Last week, a study published in JAMA Ophthalmology supported the use of anti-VEGF agents in wet age-related macular degeneration (AMD), saying that, though these drugs are costly, they may provide substantial economic value to both patients and society.

Novartis has confirmed in an email to The Center for Biosimilars® that it has launched Sandoz’s pegfilgrastim biosimilar, Ziextenzo, in the United States. According to Novartis, the wholesale acquisition cost (WAC) for Ziextenzo is $3925, or an approximate 37% discount off the WAC for the reference product, Amgen’s Neulasta.

As the only anti–tumor necrosis factor therapies currently available to US patients with inflammatory diseases, biosimilars of infliximab are increasingly used to treat diseases like rheumatoid arthritis. While there are a wealth of data on real-world use of these products in territories like the European Union, less research has examined their use in the United States. During the American College of Rheumatology’s 2019 meeting, held this week in Atlanta, Georgia, researchers reported on the results of 3 studies that assessed real-world use of biosimilar infliximab in the US context.

While US patients continue to wait for a biosimilar etanercept to become commercially available, real-world data continue to amass for Samsung Bioepis’ biosimilar, SB4, in European clinical practice. The biosimilar, sold as Benepali in the European context, was the subject of several studies presented this week at the American College of Rheumatology’s 2019 meeting, held in Atlanta, Georgia.

Among the first biosimilars to gain US approval was Sandoz’s etanercept biosimilar, GP2015, or Erelzi. The product was authorized by the FDA in 2016, but it has not yet launched in the US market due to long-running patent disputes related to Amgen’s innovator product, Enbrel. In other markets, however, the biosimilar is a widely used treatment option, and data presented at the American College of Rheumatology’s 2019 meeting, held this week in Atlanta, Georgia, show that not only is the biosimilar safe and effective in real-world practice in ex-US markets, but it could also bring about substantial savings in the United States once it becomes available.

The results will inform will inform counseling and management of pregnant women with inflammatory diseases who need tofacitinib or non-tumor necrosis factor inhibitors during pregnancy, said the author.

Over the past few years, awareness of biosimilars has been increasing; however, research presented at the American College of Rheumatology’s 2019 meeting, being held in Atlanta, Georgia, shows that while US rheumatologists hold growing awareness of biosimilars, hesitancy remains around such issues as switching stable patients and the extrapolation of indications.

The great promise of biosimilars is their ability to provide high-quality treatment at a reduced cost, thereby producing cost savings that can be reapplied. But how are healthcare systems around the globe utilizing those cost savings? During the International Society for Pharmacoeconomics and Outcomes Research 2019 meeting, held this week in Copenhagen, Denmark, several teams of researchers reported on how biosimilars are impacting international markets, and how they could provide headroom for new, expensive treatments.

Among all respondents, 53% of beneficiaries reported having had a serious problem paying a medical bill of any kind. Thirty percent of respondents said prescription drugs created the largest burden.

The International Society for Pharmacoeconomics and Outcomes Research is holding its Europe 2019 meeting this week in Copenhagen, Denmark, and the savings that biosimilars can afford European healthcare systems are a hot topic at this year’s event. Two studies presented on Monday explored how Amgen’s biosimilar bevacizumab (Mvasi) and biosimilar trastuzumab (Kanjinti) could produce significant cost savings for hospitals in the Italian healthcare system.

In a research letter appearing this week in JAMA Internal Medicine, authors from Oregon Health and Science University raised the question of whether the “large and increasing revenue from eculizumab” could be tied to off-label use for non-approved indications.

The ONWARD study included patients who initiated therapy with the biosimilar, those who switched from the reference infliximab, or those who switched from a different biologic therapy.

The American Society of Clinical Oncology (ASCO) today released its third annual National Cancer Opinion Survey, results of which highlight the added stress that the financial burden of treatment places on patients with cancer.

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.

A new research report from Milliman, commissioned by the Leukemia and Lymphoma Society (LLS), found that fewer than half of patients with blood cancer received treatment within 3 months of diagnosis, and LLS says that costs may be keeping patients from getting care.

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.

It’s widely expected that the United States will see launches of one or both of the FDA-approved rituximab biosimilars, Ruxience and Truxima, in the coming months, but just how ready is the United States to bring these products to the clinic, especially given the fact that subcutaneously administered reference rituximab has taken on such a key place in clinical practice, and given the fact that both biosimilars have so-called “skinny labels” because of issues related to intellectual property and exclusivities?

The less experience an oncologist has with administering rituximab, the more likely a Medicare beneficiary with non-Hodgkin lymphoma is to discontinue treatment, according to a new study. In addition, early rituximab discontinuation was associated with inferior lymphoma-specific and overall survival.

The Japanese Adverse Drug Event Report (JADER) database, a large, published database managed by the Pharmaceuticals and Medical Devices Agency for pharmacovigilance, collects spontaneous reports as a means to detect adverse events (AEs) related to drugs, and a newly published study used the JADER data to assess AEs related to the reference infliximab and to the biosimilar, CT-P13.

The International Society of Oncology Pharmacy Practitioners (ISOPP), which convened in London, United Kingdom, this week for its 18th international symposium on oncology pharmacy practice, has issued a new global position statement on biosimilars in therapeutic and supportive oncology.

In treating patients with moderate to severe psoriasis, Samsung Bioepis’ etanercept biosimilar, approved in the European Union as Benepali and in the United States as Eticovo, was shown to be effective in a registry study.
