A new consensus report calls the nocebo effect underrecognized in the area of biosimilars and says that more research is needed on this important topic.

Yet another class action lawsuit has been filed against AbbVie, maker of the brand-name adalimumab, Humira. The latest suit, brought by the mayor and city council of Baltimore, Maryland, on behalf of themselves and others similarly situated, alleges that, absent AbbVie’s conduct, biosimilar adalimumab could have been available in the United States as early as 2016. It also alleges that biosimilar developer Amgen was paid by AbbVie to delay its marketing of a biosimilar adalimumab.

While policymakers are grappling with ways to reduce to cost of expensive prescription drugs, one of the proposed solutions—targeting rebates negotiated by pharmacy benefit managers (PBMs)—will not on its own be enough to reduce overall pharmaceutical spending, according to a new brief from The Commonwealth Fund.

Approval of biosimilars in indications for which they were not studied directly in phase 3 clinical trials relies on the extrapolation of indications, a concept that is scientifically justified but, nevertheless, has generated some concerns among clinicians. In the case of biosimilar infliximab CT-P13 (Inflectra, Remsima), some gastroenterologists have voiced a lack of confidence in the biosimilar for the treatment of inflammatory bowel disease, including Crohn disease (CD) and ulcerative colitis. Now, head-to-head study, published in The Lancet, has produced data that may help allay those worries.

Daiichi Sankyo has announced that it is accelerating its Biologics License Application (BLA) for DS-8201, [fam-] trastuzumab deruxtecan for the treatment of patients who previously received ado-trastuzumab emtansine (Kadcyla), to the first half of 2019.

Pfizer’s biosimilar filgrastim, Nivestym, was approved by the FDA in July 2018 and launched in the United States in October 2018. Among the data on which the approval was based were 3 comparative clinical assessments of the pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, and safety of the biosimilar versus the US-licensed reference filgrastim (Neupogen) in both male and female healthy volunteers. Results from these studies were reported in full last week.

March 2019 kicked off with a surprise, when FDA Commissioner Scott Gottlieb, MD, announced he was leaving the administration. In addition, the FDA released updated draft guidance on the naming of biologics, biosimilars, and interchangeable biosimilars; approved a Pfizer biosimilar; and more.

The Center for Biosimilars® recaps the top news for the week of March 25, 2019.

The presentation at the National Comprehensive Cancer Network reviewed regulatory requirements and updates in the 2019 guidelines that affected biosimilars.

March has been a rollercoaster month for the healthcare industry. From the sudden resignation of FDA Commissioner Scott Gottlieb, MD, to the announcement of the FDA’s current thinking on nonproprietary names of biological products, I have been hearing many questions from stakeholders on what, exactly, is happening with biosimilars. Let’s take a quick look at the FDA’s latest guidance on naming and at where the FDA is headed with new leadership.

The House Ways and Means Subcommittee on Trade heard testimony this week from labor leaders and others about a revised trade agreement that some say will hurt the biosimilar industry in the United States.

This week, a research letter published in JAMA gives some insight into how biosimilars of long-acting insulins could impact the cost of insulin therapy for patients with diabetes.

Spectrum Pharmaceuticals has withdrawn its Biologics License Application (BLA) for eflapegrastim, a granulocyte colony-stimulating factor (G-CSF) therapy that the company had hoped to sell under the brand name Rolontis.

The Affordable Care Act was signed into law 9 years ago and created a biosimilars market in the United States, but what could happen if the Trump administration is successful in persuading the Fifth Circuit Court of Appeals to affirm a lower court ruling that the law is invalid?

Lupin and YL Biologics announced today that they have received approval to manufacture and sell YLB113, a biosimilar etanercept product, in Japan. The product will be Lupin’s first biosimilar to come to the Japanese market.

The FDA's updated guidance on the naming of biologics, biosimilars, and interchangeable products has caused deep concern among some proponents of biosimilars, and one stakeholder has now filed a citizen petition with the FDA in which he asks that the guidance be withdrawn.

Roche Holding AG has reached a confidential US patent settlement with Pfizer regarding its brand-name rituximab (Rituxan).

Recently, a study sought to determine whether dose reductions of anti–tumor necrosis factor (anti-TNF) therapies are possible for long-term treatment of spondyloarthritis, and found that a reduced dose is noninferior to a full dose in patients in sustained clinical remission.

Ontruzant, a biosimilar trastuzumab referencing Herceptin, shows comparable overall survival and cardiac safety, Samsung Bioepis says.

As he wraps up his final weeks as commissioner of the FDA, Scott Gottlieb, MD, talked about the factors holding back biosimilars in the United States.

Some stakeholders raised questions about how orphan drugs or biosimilars would be analyzed in the report. The Institute for Clinical and Economic Review's (ICER's) response to both were similar: it did not understand why drugs for orphan diseases or the market entry of biosimilars would lead to rapid price increases.

Like all biologics, infliximab has the potential for immunogenicity, and the development of antidrug antibodies (ADAs) can lead to loss of response or hypersensitivity reactions. A newly published paper sought to evaluate the development of a cellular response to infliximab and whether such a response could predict ADA development.

The European Commission has approved Roche’s innovator rituximab, sold in Europe as MabThera, for the treatment of pemphigus vulgaris (PV), a rare autoimmune disorder. The approval marks the first biologic approval for PV in the European Union, and the first major new therapeutic option in 60 years.

Branded drug products have fewer potential cost-saving limits on them in Medicare Part D formularies, researchers at John Hopkins University have found.

The Biosimilars Forum and Medicines for Europe today released a joint white paper that discusses how Europe has successfully sustained its multisource biosimilars market for the past 10 years. The forum also suggests that the United States make structural changes in order to achieve similar success.

The FDA maintained its requirement that all newly licensed biologics include a 4-letter suffix to distinguish each product, and even extended this requirement to interchangeable biosimilars. This provision, among others, has stoked concerns in the biosimilars industry and in many circles concerned about lowering drug costs.

A class action lawsuit has been filed by United Food and Commercial Workers Local 1500 (UFCW Local 1500) against AbbVie for alleged use of a patent thicket to maintain a monopoly for its brand-name adalimumab, Humira. The complaint also alleges that AbbVie and a number of its biosimilar competitors colluded to divide the market for adalimumab between Europe and the United States.

The administration said the update to the dashboards is part of its effort to improve transparency around drug pricing; the administration also wants to shift some Part B coverage to Part D as part of its plan to reduce total drug spending, with the idea that Part D plan sponsors would have more negotiating room with pharmaceutical companies.

Although rituximab does not carry an indication for the treatment of neurological disorders, the drug is widely used off-label as a therapy for B-cell–mediated disorders like multiple sclerosis (MS). Given the fact that rituximab has not been approved in these indications, however, data that reflect its safety and efficacy—particularly in patient populations for whom data are particularly scarce—are crucial.
