In a biosimilar trend report, Amgen discusses marketing achievements, US biosimilar policy, payer and provider acceptance of these agents, and the outlook for further growth.

The HHS plan ordered up by President Biden for combatting high drug prices is a hodgepodge of ideas that have long circulated in Washington, DC, but can any of them be made to stick? An intellectual property and FDA policy expert, Chad Landmon, JD, shares his perspective.

Reykjavik, Iceland company Alvotech said the FDA review of its adalimumab candidate is held up by pandemic-related curbs on overseas inspections.

Byooviz (ranibizumab) was approved for multiple ophthalmologic conditions, although market launch is at least 9 months away, owing to patent protections on the originator product.

Investigators said TX05 met pathologic complete response criteria for equivalence to the originator product, Herceptin. The biosimilar candidate also fell within objective response rate, immunogenicity, safety, and tolerability margins for similarity.

Alvotech gains an EU marketing recommendation for AVT02, a proposed adalimumab biosimilar; New Zealand may give preferential status to Amgen's adalimumab biosimilar; BioFactura looks to deliver ustekinumab via a robotic pill.

MIL60 bevacizumab biosimilar candidate demonstrates equivalence to the originator Avastin in a population of Chinese patients with non–small cell lung cancer (NSCLC) treated in a frontline setting.

The “patent dance” under the Biologics Price Competition and Innovation Act (BPCIA) is meant to resolve litigation efficiently, and it does, although in practice biosimilar developers and originator companies may not completely adhere to the prescribed steps, according to Biotechnology Innovation Organization (BIO) experts.

The Alliance for Safe Biologic Medicines (ASBM) has fought since 2010 in opposition of payer policies that promote automatic switching to cheaper biologics including biosimilars. The group's new chair is no newcomer to this battle.

Companies that gain Drug Controller General of India (DCGI) marketing authorization are likely in for much more extensive trials if they hope to commercialize their biosimilars on the global platform.

Refinements to the analytical testing of biosimilar candidates to verify similarity were worked into 2019 guidance from the FDA. These changes offer what the author considers a more "rational approach."

The strength of a patent wall built up around an originator biologic depends on the quality of patents that make it up and the originator company's willingness to engage in costly litigation. Part 2 of a series.

In this first part of a series, intellectual property attorneys from the Biotechnology Innovation Organization (BIO) contend that originator patents are not the formidable obstacles to biosimilars they are made out to be.

Shanghai Henlius Biotech, Innovent Biologics, and other Chinese biopharmaceutical makers are leading the wave of Asia-Pacific (APAC) biosimilar development, according to a GlobalData analyst.

Kaiser Permanente got biosimilars into circulation by building physician confidence, a strategy that a Samsung Bioepis executive says should be employed more widely.

Gary Lyman, MD, MPH, an oncologist and hematologist, explains that biosimilar substitution in the absence of interchangeability designations is widespread and not without clinical merit.

Animal toxicology studies still get included with biosimilar approval applications, although there are strong arguments that most of these studies are unnecessary. Sarfaraz K. Niazi, PhD, explains the pros and cons.

A meta-analysis of pharmacokinetic (PK)/pharmacodynamic (PD) characteristics of Sandoz pegfilgrastim biosimilar confirms biosimilarity.

Policy developments, business milestones, and physician-led efforts to shape biosimilar absorption made August 2021 an active time for these lower-cost biologics.

Misperceptions of biosimilars contribute to low acceptance of these products. Two Cardinal Health researchers discuss barriers to understanding and the importance of biosimilar education.

Byooviz, developed by Samsung Bioepis, will be distributed by Biogen in the European Union, where it becomes the first ranibizumab biosimilar. An application is under review with the FDA.

Clinical efficacy studies are not always required for biosimilars, and it's possible to resist if the FDA does ask for them. Sarfaraz K. Niazi, PhD, suggests a game plan.

Bio-Thera Solutions has found a partner to help with US distribution of its proposed ustekinumab biosimilar, which entered phase 3 trial development this summer.

Cipla, a medicines developer and retailer, and Kemwell Biopharma, a contract manufacturer, intend to produce biosimilars for lung disorders.

The International Psoriasis Council (IPC) reaches consensus on switching, patient agreement, and biosimilar safety and efficacy qualification. The IPC guidance is conservative when it comes to substitution of these products.

How many switches between a biosimilar and reference product will be sufficient to demonstrate that the risk of transitioning is minimal? A virtual study verifies the strength of FDA guidance.

A multicenter study of recombinant human growth hormone (rhGH) in children with Turner syndrome demonstrated safety and efficacy comparable to the reference product.

Use of the 351(k) biosimilar approval pathway entails legal challenges, high costs, and potentially higher clinical evidence standards. Sarfaraz K. Niazi, PhD, suggests that using the 351(a) pathway for standalone drugs and copy products may be faster and better. This is part 3 of a series.

Worries about what HHS will propose in its anticipated biologics pricing reform policy have been exacerbated by a rumored coding change.

A group of 16 advocacy groups are urging HHS to make zero co-pays for biologics a part of its prescription drug price reform program.
