The Biosimilar on TrumpRx: Pfizer Offering Further Discounts on Abrilada

TrumpRx unveiled the first 43 products listed as available through this direct-to-consumer (DTC) clearinghouse site, and one biosimilar is offered, at a discount of more than $300 per dose.

Pfizer's Abrilada is the only biosimilar offered on the TrumpRx site

Pfizer’s Abrilada is being offered through TrumpRx at a price of $207.60 per 40 mg/0.8 mL prefilled pen. The prefilled syringe version is $415.20 (for a 2 pack). This represents a 60% discount off its present low-WAC price of $519, and is 46% below the lowest recorded low-WAC price of any of the adalimumab biosimilars available (Idacio), as reported by the Samsung Bioepis Biosimilar Market Report.

Pfizer’s Abrilada is only available in one low-concentration adalimumab formula, whereas the majority of the competitive biosimilars have the widely used high-concentration formulation. Furthermore, the TrumpRx site only lists one dosage of its prefilled syringe and pen, whereas the drug is available in other doses via the prefilled syringe. Abrilada does utilize the preferred citrate-free formula.

Based on IQVIA data utilized by Samsung Bioepis, Pfizer’s share of the adalimumab market is less than 2%, and thus the company may believe that it had little to lose with this DTC pricing. Cash-paying patients will comprise a very narrow share of adalimumab purchases.

With the Federal Trade Commission (FTC) settlement with Express Scripts, reported this week, the FTC ordered the PBM to make TrumpRx accessible to insured patients as well. Since insured patients (outside of an initial deductible) will generally pay considerably less than $200 per dose out-of-pocket, and to this date a cash DTC transaction does not contribute to the patient’s deductible, this will likely remain an access point for uninsured patients who can afford the DTC price.

TrumpRx will likely add other biosimilars or biologics to its list of available products in the future. However, until the mechanism is worked out to include these DTC transactions into the plan’s or PBM’s electronic systems, this access channel will remain limited for biologic agents.

The FTC–ESI Settlement: Net Price Rules at the Pharmacy Counter

Perhaps the greatest effect of yesterday’s announced Federal Trade Commission (FTC) settlement with Express Scripts is its mandate on consumer exposure to net prices at the pharmacy counter as opposed to the inflated list prices of insulin products. But the implications go far beyond insulin. The settlement may contribute to the demise of high wholesale acquisition cost (WAC) pricing.

The FTC stated that Express Scripts would, as part of the agreement, now list preferred drugs under their low-WAC, not high-WAC, prices on standard formularies. In addition, Express Scripts will interface with the federal government’s TrumpRx site to allow the PBM’s members access to direct-to-consumer pricing platforms within its standard pharmacy benefit design.

Affecting Insulin and Beyond

All Big 3 PBMs were sued by the FTC over alleged insulin price fixing. To date, only Express Scripts has reached an agreement with the FTC. The settlement reached by the FTC may cause much consternation and uncertainty with big 3 leadership and investors, but it is unquestionably a step in the right direction.

When patients’ out-of-pocket costs are based on net pricing (that is, after rebates and discounts), their costs at the point of dispensing may decrease. This will not be the case for patients who are members of plans using fixed copayments for insulin and other products. But as Drug Channel Institute’s Adam Fein says, “The settlement helps shield patients from excesses of the gross-to-net bubble.”

“This settlement enables us to keep moving forward, and we appreciate the administration’s reinforcement of our commitment to pharmacy benefits that put Americans first,” Express Scripts said in the statement. “This is a meaningful step toward affordability for millions of families, and toward advancing the goal we share with the Administration of full transparency into prescription drug costs.”

Insulin is just the catalyst in this chain reaction. According to the latest Samsung Bioepis Biosimilar Market Report, the low WAC price of insulin glargine hovers around $18 for a single prefilled pen. On a per-patient basis, insulin is one of the least expensive biologics (at least facing biosimilar competition). Many more, higher-cost agents covered under the pharmacy benefit should follow suit.

The FTC has been called on for years to take a greater role in countering anticompetitive marketplace activities around biosimilars, including the use of patent thickets to block biosimilar competition and the use of misleading marketing information.

Significant PBM Reform Is Finally Achieved

The House of Representatives passed the long-awaited spending bill, and it was signed by President Trump on February 3rd. From the standpoint of health care, the bill failed to extend Affordable Care Act subsidies, but remarkably, major pharmacy benefit manager (PBM) reforms survived the final version.

Biologic Patent Transparency Act

Meaningful PBM Reforms, Including Rebate Pass Throughs

The Consolidated Appropriations Act of 2026 seeks to delink PBM compensation from Medicare part D list prices and subsequent rebates, opting instead for flat administrative fees. This action would reduce a PBM’s incentive to favor higher priced drugs over generics and biosimilars.

Second, the bill mandates that PBMs fully pass-through rebates they negotiate from manufacturers to plans and plan sponsors. Failure to comply with the provision may result in financial penalties imposed by the Centers for Medicare and Medicaid Services (CMS).

Third, PBMs will be required to report data to payers and plan sponsors at least every six months. The reporting must include data on rebates, formulary rationale, benefit design, spread pricing, and drug spending, all of which were infrequently shared in the past. This attempt at increasing PBM transparency should shine a significant light on the advantages of biosimilar products.

The Department of Health and Human Services will next have to specify the reporting requirements and timelines for implementation.

Rebates not Eliminated, but no Longer a Direct PBM Revenue Source

These reforms have long been sought by plan sponsors. The Act’s provisions go beyond public health plans, extending into the protected realm of ERISA and self-funded plans. In a press release, Shawn Gremminger, President and CEO of the National Alliance of Healthcare Purchaser Coalitions stated, “Today’s bipartisan passage is not only a policy win—it is a long overdue correction to a system that has lacked transparency for far too long. For years, employers have navigated a healthcare marketplace where critical information about pricing, rebates, and formulary decisions were kept out of view. These reforms finally level the playing field and put employers and working families first.”

Removing the ability of PBMs to retain rebate revenue is an important step to ensuring that the PBM acts in the best interests of their clients (i.e., as a fiduciary). However, this part of the equation is not yet been fully solved.

One interesting aspect of this foundational PBM reform is the extent it might stimulate the growth of PBM’s private-label brands. With the Big 3 PBMs already committing to various degrees the move to a pass-through rebate model, they will no doubt focus their efforts on replacing dwindling rebate revenue. Can anyone else imagine a new service fee charged by the PBMs, for simply negotiating the rebate?

The private-label biosimilar is one tool in their tool box, along with new and innovative service fees. It allows the PBM to use spread pricing, like a drug manufacturer, to pocket profits. The end result is that the PBM still has a conflict of interest, in trying to maximize its own profits by dispensing its private- label biosimilar, instead of another, perhaps less-expensive biosimilar agent.

Will These PBM Reforms Necessarily Increase Biosimilar Adoption?

Unfortunately, the rebate pass-through mandate by itself will not help biosimilar uptake: Payers will not be discouraged from preferring rebate-based pricing. Yes, rebates will still be a line item on a health plan’s or sponsor’s bottom line. Therefore, biosimilars with a low WAC price may still be disadvantaged compared with the originator when formulary decisions are made.

Rebates are not paid immediately to the plans, and I don’t believe that patients will benefit at the point of sale from the delayed savings with reduced co-insurance based on the lower net cost. That is yet to be seen. However, once larger employers see the more-transparent, mandated data reports from their PBM on rebates, lower net prices of biosimilars, and the low rate of biosimilar adoption (for biosimilars covered under the pharmacy benefit), the value biosimilars truly provide will also be transparent. This should be enough to demand formulary change—or a move to a PBM acting in the best interest of their clients and beneficiaries.

What TrumpRx Is, What It Is not, and Concerns for Biosimilars

TrumpRx is a hot topic today, especially in the context of its foundational concept: direct-to-consumer (DTC) or direct-to-patient (DTP) drug purchase and dispensing. Apparently set to launch, after the Department of Health and Human Services (HHS) issued a guidance that Secretary Robert F. Kennedy, Jr, said,  “makes clear that manufacturers can offer lower-cost drugs directly to patients without kickbacks or taxpayer billing.” The site may be ready to launch as early as Friday, January 30.

There remains a good amount of confusion how, if at all, TrumpRx fits into this DTC scheme, and to what extent the very small DTC market may affect the far larger market of commercially covered pharmacy benefits. Organizations like Mark Cuban’s Cost Plus, GoodRx, Lilly Direct, and BlinkRx already exist as pharmacies where the available products, under low DTC pricing, can be purchased by patients and shipped directly to them.

TrumpRx: So What?

On its face, TrumpRx is simply a portal that would allow a search for specific drugs and then link to these DTC vendors. From the perspective of a patient, it is a gateway to vendors offering drugs that have been heavily discounted for direct purchase—no rebates, no deductibles, no counting towards deductibles, no copays. Just a straight monetary transaction at a discounted purchase price. TrumpRx does not facilitate the sale, it does not supply the discounted drugs, and it does not accept money for the purchase. It is supposed to be accessible to pretty much anyone—the uninsured, underinsured, Medicare eligibles, and Medicaid eligibles.

With any DTC purchase, none of the transactions are registered by pharmacy benefit managers or health plans: Other than the prescription made by a health care provider, no other information enters the electronic medical record or a payer’s administrative database/billing system. From the health plan, insurer, and PBM perspective, there’s not too much to love about DTC purchases.

TrumpRx makes deals with drug manufacturers to offer their products (not all, just specific ones) at a most favored nation (MFN) price to patients. If I understand the process correctly, the drugs will then be offered by the DTC pharmacies at the negotiated MFN discount. In the early infancy of the DTC movement, individual manufacturers negotiated directly with companies like Cost Plus, and the discounts could be far lower than the expected MFN price.

What Do TrumpRx Deals Actually Entail?

A completed negotiation with the White House would allow the manufacturer’s drugs to be listed on the TrumpRx site, and be exempt from tariffs. It is not clear whether we’re talking about tariff exemptions for only those specific drugs or for the entire manufacturer’s portfolio. Considering the inconsistency of pharmaceutical tariff threats by the administration, this could be a nightmare to track and administer (in either case).

It is also unclear whether a deal with TrumpRx will exempt a single drug or all the manufacturer’s drugs from participation in the Medicare GLOBE and GUARD models, which would apply to a much larger segment of the population.

According to a recent webinar by the Academy of Managed Care Pharmacy’s legislative and regulatory team of Adam Colburn and Tom Casey, the “new DTC prices may serve as benchmarks for negotiations between payers and manufacturers.” Read that quote again. They are saying that this could knock down drug pricing for the vast commercial market, not just for the market-share sliver of cash-paying customers.

Biosimilar Considerations in This Long View

I’m not ready to go that far, not yet, anyway. Think about the implications of this possibiliity though. It would be great news for payers and terrible news for the drug industry. Also, it would be a big fat negative for the biosimilar industry: This will lower potential revenue targets for biosimilar candidates (in the same way as the Inflation Reduction Act’s Medicare Maximum Fair Price initiative), making them less attractive for biosimilar development.

Remember that the sole reason for the existence of biosimilar competition (and the industry itself) is to lower pricing substantially for high-cost biologics at the end of their market exclusivity. If something like MFN pricing (based on today’s WAC prices) is used as a starting point for commercial, Medicare, and Medicaid drug pricing negotiation, it could immediately lop off half to two thirds of the price of a biologic drug. Suddenly, biosimilar competition becomes less urgent, doesn’t it?

In Other Biosimilar News

On January 27, The Centers for Medicare and Medicaid Services announced the list of the drugs subject to the third round of MFP negotiations (this year for implementation on January 1, 2028). The set of 15 drugs predicted by Cousin and co-workers, which we reported on earlier this month was nearly spot on. Several biologics that are potential biosimilar candidates were on the list, and only Simponi (golimumab) didn’t make the final cut. This leaves Cimzia, Orencia, Entyvio, Cosentyx, Xolair, and Botox as eligible biologics this year.

An Injection of Support for the Biosimilar Red Tape Elimination Act

Thirty-seven organizations representing manufacturers, health plans and insurers, pharmacy benefit managers, corporate employers, consumers, and patients have banded together to support and hopefully reinvigorate action to pass the bicameral Biosimilar Red Tape Elimination Act.

John Murphy III

The Biosimilar Red Tape Elimination Act has been long-awaited, but it is not making much progress through Congress. As of January 22, the House version (HR 5526) has four co-sponsors since its introduction in September 2025. The related legislation in the Senate (S 1954) was introduced in early June last year, sat in Committee since that time, and similarly has gained only four co-sponsors.

In October 2025, FDA Commissioner Marty Makary, MD, stated that a draft guidance was being written to address the same objective—redefine interchangeability for biosimilars so that any approved biosimilar is deemed interchangeable. As of January 22, the bills are stuck in committee, and the FDA has not issued the anticipated draft guidance.

No Clinically Meaningful Difference Between Biosimilar and Interchangeable Biosimilars

The Association for Accessible Medicines announced the joint letter, which was sent to the chairmen and ranking members of the House and Senate committees, where the bills currently reside, asking them to “advance this crucial legislation.”

“There is no clinically meaningful difference between biosimilar and interchangeable biosimilar medicines,” said John Murphy III, President and CEO of AAM. “Interchangeability is a designation created by legislative language instead of science, doesn’t exist in any other country. We are thankful to the bill sponsors in the House and the Senate as well as the many groups who have joined us.”

“Unfortunately, the statutory distinction between biosimilars and interchangeable biosimilars continues to generate confusion and misinformation about the safety of biosimilar medicines,” states the letter. “The [FDA] has consistently affirmed that there is no scientific difference between biosimilars and interchangeable biologics.”

AbbVie, MFN, and a World of Ambiguity

On January 12, AbbVie announced that it had reached an agreement with the Trump administration on participation in its most favored nation (MFN) pricing initiative, and making certain medications available through its direct-to-consumer platform.

With the various agreements made with 15 other pharmaceutical companies, specific drugs were not disclosed. This is the first time in the short history of the MFN initiative that it involves a reference product with active biosimilar competition—that is, of publicly disclosed information.

However, the MFN (and Medicare maximum fair price for that matter) programs were explicit in their intent to avoid interfering with the biosimilar and generic marketplaces. For their part, AbbVie may simply be seeking another access channel to forestall fading Humira volume. It is not expected that the TrumpRx direct-to-consumer channel would be particularly strong.

What Is the MFN Price of Humira Likely to Be?

What would be the MFN price of Humira? Data on which the calculation derived from the administration’s international pricing index of countries with comparable economies are a bit dated, and the source has not been verified. Based on 2023 prices, Humira pricing ranges from $875 per 40 mg dose in Italy to $316 in France (of countries included in the MFN international index). Many of the adalimumab biosimilars are already providing deep discounts (some greater than 85%), to a price range of $450 to $693 for the same dose. At least one biosimilar is available through Mark Cuban’s Cost Plus at a 92% discount. What AbbVie offers under TrumpRx is unknown, but for cash paying buyers, Humira monthly cost will likely be hundreds of dollars, and largely unaffordable for most.

The point is that the biosimilar industry needs no additional impediment to its success, and most certainly, not in the adalimumab category. The reference product still retains the largest market share, and several adalimumab biosimilar makers are hanging on with miniscule volume.

In its rush to make TrumpRx MFN deals, the administration seems to have run roughshod over its own stated intention, to protect the biosimilar segment from harm. Simply, did AbbVie seek to include Humira in the arrangement, and the administration paid inadequate attention? Or did the administration seek to include Humira because of its boldface status, which would have been even stranger?

A Lack of Foresight or Lack of Principles?

Either way, this move sends a signal that the administration is conflicted about signing MFN deals for other reference drugs with active biosimilar competition. This isn’t an unintended consequence of the MFN policy; it’s a self-inflicted wound.

My original worry was that MFN, like Medicare’s maximum fair price negotiations, will discourage investment in biosimilar development. This was a problem for prospective biosimilar developers, I thought, not those with existing, approved biosimilars.

This seeming misstep is likely the result of the same “move fast and break things” mentality that has characterized this administration from the beginning of its second term. This was not a deeply considered move.

Samsung Bioepis Reinforces Its Biosimilar Pipeline

For biosimilar industry watchers like BR&R, Samsung Bioepis has played a leading role in introducing biosimilars to the US market, first with its infliximab biosimilar Renflexis. Over the years, as their biosimilar candidates were approved by the FDA, the pipeline appeared to thin, with pembrolizumab (SB27) being the sole publicly disclosed biosimilar candidate, as of the beginning of this week.

That changed very suddenly on January 15, when Samsung Epis Holdings, the parent of Samsung Bioepis, announced a healthy new slate of biosimilar candidates in early-stage development. The six additions to the pipeline include:

  • Dupilumab (reference product, Dupixent) (earliest main patent expiration, 2031)
  • Guselkumab (Tremfya) (2031)
  • Ixekizumab (Taltz) (2030)
  • Vedolizumab (Entyvio) (2028)
  • Ocrelizumab (Ocrevus) (2029)
  • Fam-trastuzumab deruxtecan (Enhertu) (2033)

When queried by E-mail, Samsung Bioepis added that each of these biosimilar candidates were developed in-house and were not licensed from other biopharmaceutical companies.

In the announcement, Kyung-Ah Kim, President and CEO of Samsung Epis Holdings, stated, “We are making great progress to secure 20 biosimilars in our portfolio by 2030.”

In addition to the newly announced biosimilar pipeline, Samsung Bioepis also updated its efforts to produce novel therapeutics. These include an antibody conjugate (SBE303) for oncology indications, which is entering phase 1 trial. This investigational innovator agent was partly the result of a global partnership with Phrontline Biopharma. The company intends to introduce “one novel therapeutic candidate into clinical study every year.”  

(Editor’s Note: The anticipated patent expiration dates are obtained through multiple sources, based on composition-of-matter patents. However, patent litigation that delays commercialization may extend beyond these principal patents.)

Is There a Place for Private-Label Biosimilars Covered Under the Medical Benefit ?

Here’s a question that has been asked repeatedly over the last year or so: Does it make sense to have private label medical benefit-covered biosimilars?

We’ve seen the spread of private-label or “white-label” biosimilars, by the big 3 pharmacy benefit managers (PBMs) specifically, for adalimumab and ustekinumab. Although we’re not sure of current market utilization of the private-label versus non–private label products, we do know that the availability of the private-label products helped biosimilars on the road to uptake if not financial success.

We have in our sights some major medical benefit–covered reference products losing patent protection and marketing exclusivity over the next few years. These include Keytruda, Opdivo, Yervoy, Perjeta, and Ocrevus to name a few. All are high-cost agents that are important (if not critical) to patient care.

The discussion of a medical benefit private-label biosimilar must tease out the potential advantages/disadvantages for both the manufacturer and the provider (who in a buy-and-bill situation makes the initial prescribing decision) or payer (who decides on coverage/reimbursement). The first assumption is that PBMs generally deal far less with specialty drugs under the medical benefit (and especially oncology drugs). By their very name PBMs manage the pharmacy, not the medical, benefit. However, their affiliated specialty pharmacies are in a viable position to play an influential role, via white bagging. If that is the case, the provider’s buy-and-bill initiative would be lost, and they would be reimbursed solely for administration services. For PBMs, earning additional dollars through their specialty pharmacy, such white-labeled products seems highly promising.

The second assumption is that heavy competition at launch for medical benefit–covered biosimilars like Keytruda will result in huge, immediate net price discounts, as seen with the highly contested adalimumab and ustekinumab biosimilar launches. Competition is competition, regardless of how a drug is covered, so this is reasonable. The bigger question is whether Medicare price negotiation or most favored nations pricing hits before biosimilars launch (they shouldn’t, according to official and draft policy, but we should account for this anyway). A lower list price will mean lower cost savings for biosimilars.

A payer might be more neutral on the private-label issue. In general, private labels have not spelled greater net savings over low-WAC biosimilar versions of adalimumab or ustekinumab. They don’t seem to be extremely motivated to insist on non-private-label versus private-label biosimilar coverage. On the other hand, plan sponsors may think otherwise, based on the call for more PBM transparency. If the PD-1 inhibitor biosimilars, for instance, were available by private label through the specialty pharmacy, it would probably have little effect on payers except reducing buy-and-bill transactions for those specific products.

With the introduction of eight new Keytruda biosimilars competing for a $30 billion US market, discounts will quickly increase—regardless of MFP or MFN pricing. It should mean a virtual (delayed) free fall in average sales pricing (ASP), which will further dissuade providers from wanting to purchase these products and take on the risk of being caught underwater. If this follows, it drives purchases and distribution through the specialty pharmacy. Will the PBMs jump at the opportunity? Are there wholesaler or other relationships that they do not currently have to be in established first?

I don’t know the answers. I hope these thoughts spur a considered discussion of the advantages and disadvantages, and where this concept leads. Please lend your voice and comment on this topic.

GLOBE, GUARD, and More MFN

Do you get the feeling we’re being deluged with news from the federal government on health regulation? That’s because we are. On December 23, the Centers for Medicare and Medicaid Services (CMS) got into the act again, announcing two new major demonstration projects that seek to cut pharmaceutical costs.

The Medicare Guarding US Medicare Against Rising Drug Costs (GUARD) and the Global Benchmark for Efficient Drug Pricing (GLOBE) models are further expansions of the Trump administration’s obsession with a Most Favored Nation (MFN) pricing approach. It has been openly discussed by the Trump administration since the President’s first term.

Whereas GUARD addresses Medicare part D covered products, GLOBE is focused on lowering the price of part B products. Biologic products are involved in both the GUARD and GLOBE models; the former includes small molecules as well. The notification language for both are identical in that they seek to avoid entangling biologics with existing biosimilar competition. Instead, eligible products are “single-source” agents only. However, like the Medicare Fair Price (MFP) provisions of the Inflation Reduction Act, this approach does not eliminate the likelihood that significant reductions in revenues of today’s single-source biologics will likely deter biosimilar development for these biologic targets tomorrow. Importantly, drugs already subject to MFP negotiations are exempted from eligibility in GLOBE and GUARD.

According to CMS, the GLOBE demonstration program will begin in October 2026 and continue for 5 years. It will be a mandatory project covering randomly selected geographic regions that will represent one-quarter of the total Medicare fee-for-service population. The GUARD demonstration program, also with mandatory participation, will begin in January 2027 and also continue for 5 years. It will cover geographic regions that represent 25% of Medicare part D plan membership.

More on the International Drug Pricing Benchmark

In terms of the MFN approach, the GUARD and GLOBE demonstration projects are consistent: They leverage an international drug pricing benchmark as a reference for drug reimbursement. It is based on drug payments in countries with a per capita gross domestic product that is within 60% of the US, and with an economy at least $400 billion in size. That includes countries like Australia, the United Kingdom, Israel, Denmark, among several others.

Another question regarding the international drug pricing benchmark is how often it might be recalculated. One of the most obvious responses by pharmaceutical manufacturers is to raise their prices in other countries, thus raising the indexed price of a drug. Also, if the pharmaceutical industry is successful in delaying the launch of these MFN-based demonstration projects, it may have ample time to boost global prices a bit. I would imagine that a 5-year demonstration period will capture this trend. One thing can be sure—prices in other countries will not be going down, unless new biosimilars are introduced!

Biosimilar Price Competition and MFN Pricing

Will the MFN approach result in lower prices than simply facilitating existing biosimilar competition and speeding its arrival? Whereas a drug like adalimumab is primarily covered under part D and would fall under the GUARD model, provider-administered agents like natalizumab would be administered by a provider and fall under part B.

The two cases can be very different in terms of pricing competitiveness. In the adalimumab case, intense competition has led to prices that are a small fraction of the original WAC price. For natalizumab, only Tyruko competes with the reference product Tysabri, and thus the wholesale average cost (WAC) difference between the biosimilar and the reference product is only 20% (based on a Drugs.com comparison). If Medicare MFP is any reference, we may be seeing one-third lower prices under GLOBE and GUARD compared with current WAC prices.

Average Sales Price Considerations in GLOBE

Under the GLOBE part B model, an important question arises as to whether it might affect or even replace average sales price (ASP)–based reimbursement for buy-and-bill products. Upon further reading, the notification specified that would not be the case. It would work as follows: The drug manufacturer would pay a rebate to the government to account for any differences between the international index price and CMS’s purchase price. This reconciliation would be made after the provider’s buy-and-bill (and reimbursement) transaction is completed. Simply put, the provider’s payment is unaffected by the later rebate. It may not be so simple, however. The ASP is supposed to incorporate all discounts and rebates. There seems to be no provision in GLOBE that the new potentially large rebates associated with eligible biologics will not be incorporated into the ASP price (thus driving it, and provider reimbursements, down).

In Other Biosimilar News

Amneal Biosciences announced on December 22 that it received FDA approval for its denosumab biosimilar denosumab-mobz to be sold under the names Boncresa and Oziltus (referencing Prolia and Xgeva, respectively). Amneal is partnered with mAbxience (which is majority owned by Fresenius Kabi) on this biosimilar; Amneal is responsible for commercialization rights in the US. This is the eighth denosumab approval in the US.

The Next Set of Biologics for Medicare Price Negotiations Predicted (and Eliminated?)

With this first post since the holidays, there is so much to discuss, yet so little firm ground on which to anchor the discussion. Since December 23, the Trump administration has added two more drug pricing reform models to the gordian knot of US pharmaceutical reimbursement, and authors from the University of Washington School of Pharmacy have published their list of drugs anticipated to be subject to Medicare price negotiation for year 3.

In this article, we’ll unpack the latter first, because it is straightforward (sort of). Based solely on Medicare expenditures and market exclusivity expiration, the researchers published in the Journal of Managed Care and Specialty Pharmacy what they believe will be the next round of drugs to be subject to Medicare price negotiation this year, for implementation January 1, 2028. The Table below lists the following biologics (of 15 identified drugs in total).

TABLE: POTENTIAL BIOLOGICS FOR MEDICARE PRICE NEGOTIATION IN 2026 FOR 2028 IMPLEMENTATION

This sunset of drugs represents the first time several biosimilar targets are included (as it is the first inclusion of part B drugs). Almost all drugs in the Table are covered to an extent under both part B and D. Indeed, the vast majority are currently the subject of biosimilar development. Some of these biosimilars will likely launch prior to 2028, before the negotiated Medicare price takes effect. Of course, predicted launch dates are dependent on patent settlements. The authors point out that other drugs are left off the list because their biosimilars are already marketed (e.g, aflibercept and denosumab) or eligibility is delayed by orphan drug rules (e.g., pembrolizumab and nivolumab, which will be eligible for selection in 2027).

If the Centers for Medicare and Medicaid Services (CMS) determine that a biosimilar launch is imminent, a request for delay in eligibility will be considered. However, CMS may seek negotiated prices if a request is not submitted, as occurred with ustekinumab. This will likely shrink the potential biosimilar revenues for these individual products. The reason CMS targets these products is that they are blockbusters. That is also the reason biosimilar manufacturers are interested in these biologics. With Medicare paying about one-third less for these agents in 2028 before biosimilar approval is obtained, they will be less interested in commercializing those agents. Consider the potential for limited market share (e.g., adalimumab), expensive patent litigation battles (e.g., nearly all products), and opportunity costs (i.e., against developing their own proprietary branded products).

Furthermore, if the ustekinumab experience is any reference, the negotiated Medicare Fair Price (MFP) will be well above the price that results from competition with several agents. The FDA is actively seeking to remove late-phase comparative trial requirements in an effort to lower development costs and reduce time to commercialization.

Today, it may make sense to modify CMS’s criteria for determining whether biosimilar launch is imminent. If a biosimilar product is already approved by FDA, this should take the reference product off the table for MFP eligibility. If three or more biosimilar products are actively in development (i.e., with FDA consultations or early-stage trials in progress) that should also eliminate the reference product from eligibility. I define three drugs as the threshold, because it should encourage significant price competition.

Drug payment and approval policies in this administration are moving all at once. We’ll review the latest salvo from CMS in the next post. However, with several biologics on the MFP list, the administration should review exactly what the value of biosimilar competition really is and how then to preserve it.
