Escaping the Void: All Things Biosimilars With Craig & G

Co-hosts Craig Burton, executive director of the Biosimilars Council, and Giuseppe Randazzo, senior vice president of sciences and regulatory affairs at the Association for Accessible Medicines (AAM), tackle the current biosimilar landscape and how the industry can emerge from the "biosimilar void."

This special vodcast series provided by The Center for Biosimilars

 was developed in partnership with the AAM and Biosimilars Council.

By Ashley Henyan, MA, MFA, director of communications at AAM

Since the passing of the Biologics Price Competition and Innovation Act in 2010, the FDA has approved over 70 biosimilar medicines. Since their entry to market in 2015, biosimilars have generated $36 billion in savings for America's patients and the US health care system. Biosimilars have proven they can unlock access to safe, effective, and more affordable treatments. But unfortunately, a dangerous trend threatens to halt progress related to biosimilar uptake and patient access. 

In February 2025, an analysis from the IQVIA Institute revealed a massive biosimilar void.

 A staggering 90% of biologic drugs losing patent exclusivity over the next 10 years have no biosimilar competition in the pipeline. This data underscores a flawed system that limits patient access and negatively impacts the livelihood of millions of Americans. 

However, when it comes to biosimilars, we have the tools to fix the problem. With the right focus, collaboration, and reforms, we can ensure biosimilars continue to bring value to patients, providers, and the broader health care system. 

With thanks to The Center for Biosimilars, this podcast series explores the current biosimilars landscape, dives into urgent actions needed from policymakers and regulators, and offers real-world insights into what changes are needed now to ensure the sustainability of the industry.

To close out the Festival of Biologics, Craig Burton and Giuseppe Randazzo from the Association for Accessible Medicines and the Biosimilars Council tackle the current biosimilar landscape and how the industry can emerge from the "biosimilar void."

This episode of Not So Different explores the possible implications of the Federal Trade Commission's (FTC) second interim report on pharmacy benefit managers (PBMs), which shed light on key issues with current PBM practices and their impact on drug prices. The report highlighted several troubling strategies, such as many cases where the big 3 PBMs were reimbursing their own affiliated pharmacies at higher rates than independent pharmacies. The report's latest findings raise important questions about the future of drug pricing transparency and regulation and challenge the notion of whether PBMs are delivering on their intended promise to benefit the health care system.

To help unpack these findings and their implications, The Center for Biosimilars

 was joined by Joe Wisniewski, an expert in PBM legislation, price transparency, and health care policy. Joe serves as assistant vice president of partnerships and government affairs at Turquoise Health and brings a wealth of insight into how PBMs are navigating the current landscape, especially with the rise of new biosimilars and shifting regulatory pressures.

This episode also explores how a second Trump administration could influence PBM practices, particularly in relation to biosimilars, and what that means for drug pricing efforts moving forward.

On this episode of Not So Different, we explore the Federal Trade Commission’s (FTC) second interim report on pharmacy benefit managers (PBMs) with Joe Wisniewski from Turquoise Health, discussing key issues like preferential reimbursement, drug pricing transparency, biosimilars, shifting regulations, and how a second Trump administration could reshape PBM practices.

Will the FTC Be More PBM-Friendly Under a Second Trump Administration?

As 2023 comes to a close, we look back on some of the major advancements from the past year, from the long-awaited market introduction of adalimumab biosimilars in the US, to the first major regulatory approvals for neurology biosimilars, to the implementation of key policy initiatives around the globe.

A lot of eyes have been on the United States and 2024 shapes up to be another big year for the biosimilar industry, with approvals for denosumab, aflibercept, and on-body pegfilgrastim biosimilars on the way. Additionally, the nation will continue to see the fallout from the implementation of the Inflation Reduction Act (IRA), including its policies regarding Medicare price negotiations, as well as the role interchangeability designations will play into adoption rates. It also remains to be seen whether payers and pharmacy benefit managers (PBMs) are ready to embrace newer biosimilars and add them to formularies as preferred products, leaving the future for a sustainable biosimilar industry up in the air.

Today, I'm joined by Brian Biehn, senior director of biosimilar commercialization, and Corey Ford, vice president of reimbursement and patient access, and policy insights at Cencora (formerly AmerisourceBergen). Both of them have been keeping a close watch on the biosimilar space throughout the year and today's discussion will surround how this year sets up a new chapter for the industry.

A New Chapter: How 2023 Will Shape the US Biosimilar Space for 2024 and Beyond

In late October 2023, the FDA approved Zymfentra (infliximab-dyyb), the world's first subcutaneous infliximab product. The product's development was based on Inflectra (infliximab-dyyb), an intravenous infliximab biosimilar referencing Remicade (infliximab). However, because the reference product does not have a subcutaneous option, Zymfentra was approved as a novel agent.

Zymfentra is also approved in Europe, where it's marketing under a different brand name. The product was developed by Celltrion, a Korean biopharmaceutical manufacturer that's shaping up to be a big player in the US biologics space. Zymfentra's subcutaneous presentation allows for easier and more convenient self-administration for patients, particularly those with inflammatory bowel disease (IBD), an umbrella term for ulcerative colitis and Crohn disease.

Zymfentra is also unique in that it was approved using data from 2 trials testing the product vs placebo in patients with ulcerative colitis and Crohn disease. Typically, infliximab biosimilars are tested in patients with RA or PsA and receive extrapolated indication for gastroenterology conditions. The LIBERTY trials offer gastroenterologists who may be wary of a subcutaneous infliximab option a degree of confidence that Zymfentra is safe and effective for patients currently on intravenous infliximab treatments.

We spoke with Andres Yarur, MD, a researcher on the LIBERTY trial and an associate professor of medicine at Cedars-Sinai Medical Center, to discuss the significance of his trial, the approval of a subcutaneous infliximab option, and what both mean for the future of IBD care.

Biosimilars Regulatory Roundup for September 2023—Podcast Edition

The newest field of health care to experience biosimilar competition is the ophthalmology space, particularly the retinal disease treatment sector. Currently, the United States and the United Kingdom each have 2 ranibizumab biosimilars and the European Union only has 3, all of which were approved in the last 2 years. Additionally, more ranibizumab biosimilars referencing Lucentis and a slew of aflibercept biosimilars referencing Eylea are expected to enter the market over the next few years. Although all data shows these products to be bioequivalent to their reference products, the lack of real-world evidence around the world has left many ophthalmologists and biosimilar experts struggling to gain clarity on the safety of these products.

Furthermore, there is even more confusion about the meaning of interchangeability after 1 ranibizumab product (Cimerli) was granted an interchangeability designation by the FDA despite the label only applying to products dispensed through pharmacies and the label being granted without requiring data from a switching study.

Today, I’m joined by Sarah Yim, MD, director of the FDA’s Office of Therapeutic and Biologics and Biosimilars, to discuss these issues and the FDA’s efforts to instill public confidence in ophthalmology biosimilars. Dr. Yim has worked extensively to help create the FDA’s education material on biosimilars and spread the FDA’s view that biosimilars are as safe and clinically effective as their reference products. 

Prior to her work at the FDA, she was a clinical fellow at the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Disease and served as a medical officer for the US Army for over 10 years. She also hosted the FDA’s workshop on increasing efficiency within biosimilar development programs, presented at the DIA Biosimilars Conference, and was a featured panelist for our most recent LinkedIn Live event on ophthalmology biosimilars last fall.

Biosimilars Regulatory Roundup for August 2022—Podcast Edition

On this week’s episode, we’re breaking down the possible impact that Humira biosimilars will have on health policies across the United States. Come 2023, the United States will welcome at least 7 biosimilars referencing Humira (adalimumab) to the market, catapulting the adalimumab market to the number 1 spot as the biosimilars space with the most competitive products referencing the same molecule. One of the biggest concerns regarding these launches is how providers, practices, and payers are going to adapt to ensure that patients have access to adalimumab biosimilars and that practices aren’t overwhelmed trying to keep up with multiple versions of the same product.

The Center for Biosimilars spoke with Chronis Manolis, senior vice president of pharmacy at UPMC Health Plan. He has a lot of experience working in the health plan space, especially regarding policy and relationships with pharmacy benefit managers, a rather contentious topic in present day biosimilar discussions. Manolis is also a proponent of the idea that providers and payers could work together to promote biosimilar use and has been keeping eye on the developing adalimumab space.
