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.

Where Do Biosimilars Fit into the Cancer Treatment Puzzle?

The incidence of cancer is expected to increase to 30 million patients worldwide by 2040. However, the introduction of biosimilar medicines, both as treatment and supporting therapy for cancer patients, has created a significant opportunity to make cancer care more accessible, thereby improving patient outcomes and reducing the health care burden globally.

Everyone across the world involved in the fight against cancer—including patients, health care workers, policymakers, and governments—was invited to take part in IGBA’s Global Biosimilars Week 2023 webinar. During the event, discussions focused on how all stakeholders could collaborate to expand global cancer care, with a special emphasis on the role of policies related to biosimilar medicines.

IGBA’s fourth annual Global Biosimilars Week (GBW) is taking place from  November 13-17, 2023. The mission of this online, social media–focused campaign was to raise awareness of the powerful and life-changing impact of biosimilar medicines. The theme this year is "Making Cancer Care More Accessible to Patients and Healthcare Systems."

Webinar: Where Do Biosimilars Fit Into the Cancer Treatment Puzzle?

Stephen Hanauer, MD, professor of medicine, Feinberg School of Medicine, Northwestern University, highlights the importance of his study comparing an adalimumab (Cyltezo) with the refrence product (Humira) patients with gastroenterology conditions.

What role can your trial play in improving patient and provider confidence in using adalimumab biosimilars for Crohn disease and ulcerative colitis?

The study actually provides additional reassurance regarding the biosimilarity and the potential of patients switching from either the [reference product] to the biosimilar or substituting the biosimilar from the onset.

Why are more clinical studies on anti-TNF [tumor necrosis factor] medications in gastroenterology conditions needed and how can providers and health systems be better advocates for these types of trials? 

Firstly, there still is room for improvement in efficacy within the TNF class. We're not getting 100% remission rates and we know that remission rates can be improved with the addition of immunomodulators for instance, or dose escalation in some situations. In addition, we are seeing newer TNF formulations—for instance, of subcutaneous infliximab—as a maintenance therapy. So, as additional biosimilars are coming out, we also have additional new products of the same class that are being evaluated and offer patients different opportunities, for instance, of intravenous versus subcutaneous formulations at different intervals.

Stephen Hanauer, MD, professor of medicine, Feinberg School of Medicine, Northwestern University, shares why his study comparing the safety and efficacy of Cyltezo, an adalimumab biosimilar, with the originator (Humira) matters for patients with gastroenertology conditions.

Dr Stephen Hanauer: Why More Studies Assessing Adalimumab Biosimilars in Gastro Conditions Are Needed

Michael Kleinrock, lead research director for the IQVIA Institute for Human Data Science, made predictions on what will drive biosimilar uptake and savings over  the next 5 years using the data from 

IQVIA's Biosimilars in the United States 2023-2027 report

 at Access!, the annual meeting of the Association for Accessible Medicines in Orlando, Florida.

The latest IQVIA Biosimilars in the United States report predicted that spending on biosimilars will increase to $129 billion and generate $180 billion in savings over the next 5 years. What are going to be some of the biggest drivers for these numbers going forward?

Obviously, the biggest drivers in the next few years are adalimumab biosimilars. But there's other products in the same category: ustekinumab (Stelara) biosimilars is coming very soon. There's also some other areas, like age-related macular degeneration. So, ranibizumab and following slight thereafter is aflibercept. 

But we have a an outlook with a number of these medicines that we think are going to have a reasonably big impact on the dollars going to the biosimilars, as well as to the savings. We also profile a significant set of uncertainties we feel like in terms of the uptake and the different behavior of individual companies in marketing the biosimilars. How competition has so far worked out in terms of the concentration in the market. 

Imagine a circumstance where there's a large number of companies challenging one particular molecule and not all of them make their return. The sustainability of the market for biosimilar makers is a key question, as well as the sustainability if biosimilars are not entering the market or are lower selling than originators. So, a lot of questions that really frame the future of this sector where there are 300 or so molecules that are biologics, and so far, we have 39 of them with approvals or are in the pipeline, and many more that have not yet begun that journey; it's unclear how many will.

The report focused a bit on the US market introduction of up to 10 adalimumab biosimilars, including Amjevita, which just launched at the end of January 2023. How do you anticipate this portion of the biosimilars market developing through 2027 and what are going to be the main factors driving utilization trends for these products?

The thing that we include in a couple of the exhibits in the report is is an assessment of the adalimumab market for a couple of key dynamics. 

One, you mentioned, is the number of challengers, but the other is the nature of the originator. Subsequent to the original launch of adalimumab, there have subsequently been reformulations, with a high-potency and citrate-free formulation and a significant migration of the current patients to this newer formulation. Not all of the biosimilars are formulated the same way. There is a difference in the administration a patient would experience and perhaps those benefits are valuable to patients and providers. 

So, there's definitely a question of essentially as an analog, when we think about what adalimumab is doing in terms of continuing to move that innovator forward, how that has played out in other molecules when we see that in filgrastim and pegfilgrastim. When we see that in the breast cancer market with trastuzumab and other related products from the originators [Herceptin]. The relevant market of the originator that the biosimilar is similar to may not be the same when we get our biosimilars to the market as it was when the development program started. 

Understanding how that market is going to evolve and whether the value of subsequent innovations is telling, or whether the cost savings is the telling feature, all of those are influenced by the negotiating power of the different participants. The more challengers there are, the more game theory comes into play and the more nuanced and generally the deeper the price erosion and volume erosion tends to be. 

Fewer competitors tends to result in lower price discounting as well. And those are patterns that we've seen go back to small molecules and back to the beginning of the H

 So, we should expect to see many those things come out. But it's going to be interesting to see what the participants do. 

Probably my key observation on this is the way in which the originators participate in these markets. We've seen a mix. Historically, we've seen originators essentially exit—not lower their price post expiry, not compete on price with the biosimilars essentially. We've also seen them lower their price and essentially compete for the volume and the contracts after the presence of biosimilars. 

Those will have an effect, and there is a scenario you can imagine where this system, society as a whole, saves money because of the presence of biosimilars but the biosimilar maker isn't rewarded for it commercially. That could be one of the outcomes we see here; it's a lot of money that we're talking about. These are big selling products sometimes. The amount to play for is certainly motivating and that's why you're seeing, as you said, as many as 10 competitors, and some of the other products have a similar number.

Adalimumab and ustekinumab biosimilars aren't the only factors that will drive biosimilar adoption and savings through 2023, according to Michael Kleinrock, lead research director for the IQVIA Institute for Human Data Science.

What Will Be the Major Drivers Behind IQVIA's Predicted Biosimilars Uptake, Savings?

Ian Henshaw, senior vice president and global head of biosimilars at Biogen, gives his thoughts on the necessity of clinical efficacy testing for biosimilar approvals, switching studies to establish interchangeability, and the promotion of biosimilars within company environmental and social impact reports.

Lately, there have been a number of efforts to try to remove clinical efficacy testing for biosimilars and to remove switching study requirements for establishing interchangeability. What is Biogen’s view on these efforts and do you think removing these requirements would create more confusion about biosimilar safety?

The intent of these discussions is to maybe open up the market. Some may see it as to lower the threshold. But we should recall that the body of evidence to get a regulatory approval is generally only the preclinical aspect. So, it's about the technical process, the manufacturing, etc. If we divide the clinical studies into 2, phase 1 and/or phase 3, you need to probably keep phase 1 for the right reasons, except in certain circumstances where you don't want to be putting an active drug into, say, an eyeball. 

If you did, under the scenario that you did eliminate a phase 3 study, because the body of the totality of evidence found—for example, in Europe, is 1 million patient-years of data—you would then say, "Does that prove anything? Is it necessary in terms of confirming comparability between the innovator and the biosimilar?" In that circumstance, you wouldn't do switching studies, and therefore, you wouldn't have an interchangeability discussion. 

But I think the discussion is, if the body of evidence is within the early preclinical stage, which is about comparability within certain tolerances and also includes a phase 1, you've probably covered most of the question marks around switching from one biologic to another biologic to another biologic, which, by the way, is what happens when you go from one innovative batch to another innovative batch to another innovative batch. They're all similar to the first reference batch, and I think that is where the body of evidence and real-world data starts to come to play and actually opens up the possibilities of this marketplace.
