While there is no question that falling prices that come with competition are cause for optimism in the United States, which is burdened by rising drug costs, some experts from Europe caution that a focus on price alone misses key reasons to use biosimilars.

Researchers from biotech company Tetra Therapeutics have reported that, in their retrospective population-based study of 56 million patients with inflammatory diseases, use of anti–tumor necrosis factor (anti-TNF) agents was linked with a reduced risk of Alzheimer disease.

Generic drug maker Lannett Company announced positive results from the beginning of a clinical program for its proposed biosimilar insulin glargine referencing Lantus.

Drug developer Biocad received approval for its rituximab biosimilar, BCD-020 (Acellbia) in Russia in 2014, and since that time, the drug has been launched in Russia and in multiple other markets around the world. While Biocad has not specified whether it plans to pursue regulatory approval for the biosimilar in the European Union, the company has announced ambitions to enter the EU market with some of its products, and researchers have published new data for the biosimilar in both oncology and rheumatology indications.

Amgen and pharmacy benefit manager (PBM) Abarca this week announced that they have entered into an outcomes-based contract for brand-name etanercept, Enbrel.

Trade representatives for Canada and Mexico met last week over the ratification and implementation of the United States–Mexico–Canada Agreement (USMCA), and press reports say that the Trump administration is considering acceding to Democrats’ demands to reduce patent protections for reference biologics in order to get the pact through Congress.

The Federal Circuit, in Arthrex, Inc v Smith & Nephew, Inc, ruled that the appointment of Administrative Patent Judges (APJs) at the Patent Trial and Appeal Board (PTAB) violated the Appointments Clause of the US Constitution, and held that APJs could be removed from office without cause. Absent a dramatic ideological shift in the PTAB, however, this decision likely will have little impact on how follow-on biologics developers use inter partes review (IPR).

In Crohn disease (CD), anti–tumor necrosis factor therapies like adalimumab have provided an alternative to long-term corticosteroid therapy and have reduced the need for many patients to have surgical interventions. It has been proposed that early treatment with biologics may lead to better outcomes and fewer complications—like strictures and fistulae—and findings from a recent study support that assertion.

HR 3 proposes targeting for negotiation those drugs that consume a large share of the healthcare budget and that have limited biosimilar or generic competition. Writing in a perspective article in The New England Journal of Medicine, Peter B. Bach, MD, MAAP, a noted critic of high drug prices, proposed a different set of targets.

With debate and argument over what is to blame for high drug pricing, this report sought to examine the executives’ reasoning and attitudes behind pricing decisions.

The government should ensure that practices that unfairly inhibit biosimilars competition do not occur. We do not want to discourage normal competition. Biologics are not a natural monopoly, and competition is feasible, as demonstrated around the world. Biologics have provided great benefits; nevertheless, some policies can be adopted to maintain incentives for innovation but still allow increased competition from biosimilars.

The European Commission has released a new report that highlights the role that biosimilars and generics will have in the wellbeing of European healthcare systems in the years ahead.

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.

Universal access to affordable essential medicines remains an unmet goal, and while the World Health Organization has been attempting to address this problem through prequalification of drugs like insulin to help ensure access for patients in low-resource areas, costs for many products remain prohibitive.

Data on the safety and efficacy of biosimilar infliximab CT-P13 (Inflectra, Remsima) in treating inflammatory bowel disease (IBD) continue to accrue, in both adult patients and in pediatric patients, and a study from Finland adds to that body of knowledge, while another study in pediatric patients shows that Janus kinase (JAK) inhibitors may be an option for those who do not respond adequately to infliximab or other biologic treatment.

During November, biosimilar developers announced a spate of new business agreements and acquisitions. November also saw biosimilars approved and launched, and innovator products’ sales slipping.

The Center for Biosimilars® recaps the top stories for the week of November 25, 2019.

Researchers have hypothesized that signaling through the vascular endothelial growth factor (VEGF) pathway could have immunomodulatory effects, and a recent study reports on a phase 2 trial that assessed a combination of the immune checkpoint inhibitor nivolumab with the anti-VEGF agent bevacizumab, which now has a commercially available biosimilar.

The fact that biologic drugs are typically infused or injected poses numerous challenges, including discomfort for patients, instability under some storage conditions, and the generation of needle waste. Researchers have long sought a way to deliver biologics orally, and some teams have even reported progress toward the goal of delivering monoclonal antibodies in coated tablet forms. Now, researchers have reported in Nature Medicine that a luminal unfolding microneedle injector could be a feasible delivery device for biologic drugs like insulin.

Biocon announced today that its supplemental Biologics License Application (sBLA) for its biosimilar pegfilgrastim, Fulphila, filed with partner Mylan, has been approved by the FDA.

Coherus BioSciences and Amgen have reportedly settled a patent lawsuit over biosimilar adalimumab.

The draft guidance on clinical immunogenicity testing for insulin products is indeed a historic event: a bold step by the FDA that shows a determination that there is a need to bring into market lower-cost alternates to the reference products if the clinical studies that contribute to the majority of cost and time are not required.

A recent study assessed tofacitinib versus anti–tumor necrosis factor (anti-TNF) agents using data from the Corrona registry, a large, prospective, observational database of patients with rheumatoid arthritis (RA) in more than 174 practices in 41 US states.

The issue of whether to switch patients currently taking biologics to biosimilars has been playing out in Canada over the past week, as mandated switching begins in British Columbia, while a reference product maker fights against a possible similar change in 2 other provinces.

Because stand-alone pharmacokinetic (PK) studies are usually designed to focus on intrinsic and extrinsic factors that have a high potential to affect drug exposure, they leave other possible interactions unstudied; population PK (popPK) analysis allows for an assessment of multiple factors that are not otherwise evaluated in healthy volunteers and allows for a larger number of individuals to be included.

Celltrion Healthcare announced that the European Commission has authorized Remsima SC, a subcutaneously administered formulation of its biosimilar infliximab, CT-P13, for the treatment of rheumatoid arthritis. The product is the first subcutaneous infliximab option to be approved in any regulatory territory.

The FDA today released draft guidance for industry on clinical immunogenicity considerations for biosimilar insulins and interchangeable insulins. The guidance document provides recommendations as to whether—and when—comparative clinical immunogenicity studies will be needed to support an application to the FDA for insulin products under the biosimilar approval pathway.

How much does the price of common drugs vary across the globe? A UK digital healthcare startup collected that information to display the disparities across 50 countries for 13 often-used pharmaceuticals, including adalimumab and insulin glargine.

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.

During the European Society for Medical Oncology Asia Congress 2019, held last week in Singapore, a research team led by Binghe Xu, MD, PhD, department of medical oncology at the Cancer Hospital Chinese Academy of Medical Sciences, Beijing, China, reported that the biosimilar met its primary end point of best overall response rate at week 24.
