Exploring the Biosimilar Horizon: Julie Reed's Predictions for 2024

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.

The Subcutaneous Revolution: Zymfentra and the Future of IBD Care With Dr Andres Yarur

With US' market experience with biosimilars approaching a decade, industry experts are beginning to look into ways to accelerate biosimilar development to make more lower-cost products available to patients quicker. Strict regulatory guidelines require manufacturers to conduct numerous expensive and time-consuming preclinical and clinical trials to obtain approval and prove that biosimilars are safe and effective. However, research has shown that not all of these tests may be necessary anymore and there's might be ways to cut down on development spend without compromising safety.

A commentary paper written by 4 representatives from pharmaceutical companies sought to provide an unbiased perspective on this objective can be achieved, noting that extensive testing was needed when biosimilars were new but approval requirements should be updated as the industry gains new information.

Today, I'm joined by Julie Reed, executive director of the Biosimilars Forum, a nonprofit organization aimed at the advancement of biosimilar adoption through collaboration with biosimilar manufacturers. The companies that the paper's authors represent (Samsung Bioepis, Sandoz, Boehringer Ingelheim, and Fresenius Kabi) are all members of the Forum and our discussion with Reed will highlight some of the major pieces from the paper and next steps for the industry to propel biosimilar development into the future.

How Streamlining Development Can Save the US Biosimilar Industry

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.

Recently, Amgen released the latest update to its Biosimilar Trends Report, detailing some of the big successes for biosimilars in the United States since their market introduction in 2015 as well as current market trends, predictions for the next phase of biosimilar competition, and advice for stakeholders going forward. The report also gave insight into how biosimilar policies, such as reimbursement structures, could develop in the future and whether the United States is heading towards greater biosimilar adoption.

On this episode, I’m joined by Chad Pettit, the executive director of marketing and global biosimilars commercial lead at Amgen. Chad is a long-time friend of The Center for Biosimilars, having spoken to us in video interviews in the past about previous version of this report. He was also a recent panelist at the DIA Biosimilars Conference that was held in September 2022 and has been working with Amgen since 2000. He’s been working to advance biosimilars since 2014 and is considered a market expert on the biosimilars industry.

What Amgen’s Biosimilar Trends Report Says About the Future of Biosimilars

Despite some biosimilars, including those for filgrastim, trastuzumab, and bevacizumab, achieving a greater US market share than their originators, other biosimilar categories, such as pegfilgrastim and infliximab, are still trailing behind. Some biosimilar companies are becoming more savvy, developing new ways to make a bigger statement in the market.

We sat down with Kirollos Hanna, PharmD, the manager of Oncology Pharmacy at the University of Minnesota Medical Center, an associate editor for the Journal of the Advanced Practitioner in Oncology, and an assistant professor at the Mayo Clinic School of Medicine, to discuss what tactics biosimilar companies are using to better compete alongside originator manufacturers.

Not So Different: How Biosimilar Companies Are Stepping Up Their Game to Compete Against Originators

Although the European Union has been in the biosimilars game longer than the United States, both are considered leaders in biosimilar use. Generics were the first copycat drugs, however, there are lessons to be learned from this experience. But biologics, which are made from living organisms, are not as simple to copy as generics are. There will be minute differences between biosimilars and originator biologics, and there will even be small differences between different batches of the same originator biologic. We now have reliable tests for determining whether these differences are clinically significant or not. But what does our experience so far with biosimilars and originators tell us about these differences?

We sat down with Paul Cornes, BM, BCH, MA, MRCP, FRCR, a consultant oncologist and biosimilars expert who was part of the team that developed and presented evidence to the FDA for the first successfully approved US biosimilar, Zarxio, a filgrastim product developed by Sandoz. Paul helped explain these issues.

Not So Different: Should Biosimilar Variations Be Concerning?

Shanghai Henlius Biotech is a growing China-based biopharmaceutical manufacturer that’s been working in the biosimilars space for some time. The company recently got approval for their 40 mg/ml low-concentration adalimumab biosimilar in December 2020 and is currently focused on marketing that in China. They have a plan to develop a high-concentration adalimumab biosimilar in the future to compete alongside AbbVie’s high-concentration formulation of the reference product, Humira. The company is also in the process of developing biosimilars for programmed death-1 (PD-1) inhibitors, which are used to treat several types of cancers.

We sat down with Ping Cao, vice president of Business Development for Henlius, to discuss the company’s current biosimilar development plans and how the regulatory process in China differs from those of Europe and the United States.

GBW 2025 webinar

Health care systems around the world are facing increasing challenges—from rising costs to gaps in access. Biosimilar medicines offer a promising solution, helping make care more accessible, affordable, and sustainable for patients everywhere. These goals align closely with the United Nations’ Sustainable Development Goals for Health by 2030, and today’s discussion will explore how biosimilars can help make that vision a reality.

This webinar is part of the sixth Annual Global Biosimilars Week, running from November 3 to 7, 2025. The theme this year—“Biosimilars: A Wise Investment for Global Health”—perfectly captures the spirit of this conversation and the opportunities ahead.

These were questions asked by the audience during the live broadcast of the webinar. The speakers provided responses after the webinar ended. Below are their responses and insights.

Are there examples of biosimilar-driven access improvements that could be replicated in other regions?

There are examples available in the IGBA Biosimilar Access Policy Blueprint (2021) as well as in IGBA Biosimilar Communication Resources (Module 5 - The benefits of biosimilar medicines). Translating the biosimilar availability opportunity into tangible access development is always a matter of policy framework and policy interventions that transform the cost-effectiveness gains into investment in better use of resources and more efficient processes.

The 2024 NCD Best Buys report aims at supporting WHO member states to prioritize and scale up the implementation of the most impactful and feasible interventions in the national context. Off-patent medicines, including biosimilar medicines, are part of the best buys. Could you tell us more about the overall progress so far to meet the 2030 goals? (Are we on course? Are we delayed?)

The target established by WHO is for 80% availability. While there has been movement, it is not even across all regions and also varies between the private and public sectors, with private sector availability being slightly higher. The ranges are 38-68% in the public sector and 42% to 77% in the private sector. Some of the challenges are high prices, where many countries pay higher amounts than the international reference price, including both acute and chronic conditions, and where also there is increasing dependency on out-of-pocket payments.

In Mexico, will the government be adopting a streamlined biosimilar development pathway that removes the requirement for phase 3 (comparative efficacy) studies?

Currently the requirements by the local rules include the requirement for clinical trials to demonstrate efficacy and safety. In Mexico, the biosimilars are called biocomparables. Below there is more detail about it.

In my experience, the requirements related to clinical trials are case-by-case; in the end, the opinion of the New Molecules Committee and Biotech Products Evaluation Subcommittee (NMC/BPES) will determine the specific requirements for approval of each biocomparable biotechnological medicine. This opinion is based on the documentation presented in the CTD modules 2, 3, 4, and 5. During my presentation, I also mentioned that for biosimilars, the presubmission meeting before NMC/BPES is mandatory.

For biosimilars, below I have described some preclinical and clinical requirements indicated in the local rules, but this can be extended case by case:

“...The application must include the documentation outlined in Sections I to IX of Article 177, as well as preclinical and clinical studies such as:

Any other studies determined by the Ministry, based on the opinion of the New Molecules Committee.”...

“...III. Reports of preclinical studies in animals must include comparative data between the reference biotechnological medicine and the biocomparable product. These studies must be conducted in relevant animal species and include, as determined by the New Molecules Committee:

Comparative pharmacokinetic study reports, when required by the Ministry, to demonstrate pharmacokinetic biocomparability between the biocomparable and reference products, based on key parameters.”...

How many biosimilar products have been approved through reliance pathways in Mexico so far?

This data is not available. However, in my presentation I mentioned that during almost 4 years the reliance applied to participate in tenders without MA issued by COFEPRIS, applicable only for tenders to supply public institutions Therefore, some products that participated with MA issued by recognized authorities could be identified during the tender processes (small molecules and biosimilars), but there is no official data about the total number of biosimilar products approved through reliance pathways.

In the future, probably based on the last publication in July 2025, for the application of the abbreviated regulatory pathway (equivalence agreements), the approvals might be differentiated.

Regulatory convergence is improving among EMA, FDA, and WHO, but not all dossiers will meet these new standards.Will companies need to conduct new studies, and how might that affect costs or timelines?

 entitled “Developing a Regulatory Policy Framework Supporting Biosimilar Competition: The Opportunity for Tailored Clinical Biosimilar Development” where 2 important points were made:

A global regulators roadmap towards streamlined biosimilar development program should be adopted - maintaining the scientific and regulatory rigor is needed to support approval, and allow for tailored clinical development.

The role of regulators extends beyond approval to include education for healthcare professionals to understand the analytical science that underpins biosimilarity, ensuring that regulatory approval translates to utilization of biosimilar medicines.

Today, in 2025, both remain cornerstone to harvesting the benefits of streamlined development. The asynchrony of adoption of the new standards will require developers to at best maintain extended developments (including unnecessary studies) or worst to have 2 developments for the different jurisdictions, although this is unlikely to be retained as a viable option. This points to all international regulatory convergence initiatives (eg, ICH, IPRP, ACCESS consortium) as key drivers for access.

A significant evolution of the regulatory requirements in underway in the global regulatory community (so called streamlined clinical development) offering the perspective of biosimilar developments for more biologic medicines. How can the WHO efforts be amplified, notably in promoting harmonisation of standards (through the guidelines and their implementation) or through collaborative or reliance initiative?
