How a $37,000-a-year medicine sets a good model for drug pricing

1. Executive Summary

This report provides a comprehensive analysis of Dupixent’s (dupilumab) pricing model to assess its viability as a “good model” for pharmaceutical pricing. Dupixent, a groundbreaking biologic for chronic inflammatory diseases, commands an annual wholesale acquisition cost (WAC) of $37,000, though its average net price is closer to $31,000. The analysis reveals that while Dupixent’s pricing aligns with established value-based thresholds, indicating significant therapeutic benefit relative to cost, and is supported by robust patient assistance programs, it simultaneously highlights systemic challenges. These challenges include the pervasive opacity in pricing, the considerable strain on healthcare budgets, the limited competition for biologics, and the ethical complexities of uniform pricing across multiple indications.

The findings suggest that Dupixent exemplifies successful pharmaceutical innovation that delivers substantial patient value. However, its pricing model, when viewed through the lens of equitable access and systemic affordability, presents notable limitations. A truly effective drug pricing model for the future must integrate the incentives for innovation inherent in market mechanisms with proactive, strategic regulatory interventions. This includes enhancing transparency, fostering timely competition for biologics, exploring flexible pricing strategies such as indication-specific pricing, and strengthening governmental negotiation capabilities. Such a multi-faceted approach is essential to cultivate a sustainable, transparent, and equitable drug pricing ecosystem that benefits all stakeholders, particularly patients.

2. Introduction: The Complex Landscape of Pharmaceutical Pricing

Overview of US Drug Pricing Challenges and Global Disparities

The United States healthcare system faces persistent challenges associated with high prescription drug costs, with per capita spending significantly exceeding that observed in 32 other countries, including France, Australia, and Japan.¹ This pronounced disparity is largely attributable to the U.S.’s predominantly market-driven pricing model, which features limited direct government controls, a stark contrast to the more regulated systems prevalent in Europe and other nations that frequently employ mechanisms such as International Reference Pricing (IRP) or Health Technology Assessments (HTA).²

The complexity of drug pricing in the U.S. is further compounded by intricate private price negotiations occurring at various points across the pharmaceutical supply chain, convoluted reimbursement systems, and a multitude of payment methods.¹ This opaque and fragmented system contributes to a pervasive lack of transparency, which in turn erodes public trust and impedes the ability of both patients and payers to make informed decisions.² The U.S. drug pricing landscape, while intended to spur pharmaceutical innovation through market forces, results in higher drug prices and a significant lack of clarity. This suggests that without adequate regulatory oversight, market forces alone may not achieve optimal outcomes for public health and affordability, as the market does not appear to effectively drive prices down through robust competition, but rather enables higher prices due to the inelastic demand for essential medicines and the inherent information asymmetry between drug manufacturers, payers, and patients.²

Introducing Dupixent: Its Therapeutic Significance and Initial Market Positioning

Dupixent (dupilumab), a significant biologic drug co-developed by Regeneron Pharmaceuticals and Sanofi, has received regulatory approvals for a range of chronic inflammatory diseases driven by type 2 inflammation.⁴ These indications include moderate-to-severe atopic dermatitis (eczema), asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), eosinophilic esophagitis, prurigo nodularis, chronic spontaneous urticaria, and chronic obstructive pulmonary disease (COPD).⁷

The drug represents a substantial therapeutic advancement for conditions that previously had limited effective treatment options. It has demonstrated significant clinical benefits, such as reducing skin lesions, improving clearance rates, alleviating itching, and decreasing the reliance on oral corticosteroids.⁴ Following its initial FDA approval for moderate-to-severe atopic dermatitis in 2017, Dupixent’s indications have expanded considerably, solidifying its status as a “blockbuster” product in the biopharmaceutical market.⁷ The initial annual wholesale acquisition cost (WAC) for Dupixent was reported at $37,000.⁷ The consistent characterization of Dupixent as a “breakthrough” and “first-in-class” therapy for conditions with significant unmet medical needs directly correlates with its high initial price.⁷ This points to an established practice within the pharmaceutical industry where novel, highly effective therapies addressing critical health challenges often command premium pricing. This premium is typically justified by the perceived value these drugs deliver and the initial absence of direct competition, setting a precedent for how pharmaceutical innovation is financially rewarded in the market, often prioritizing the return on investment for the innovator before any potential future price reductions that might arise from increased competition.¹⁴

3. Dupixent’s Pricing Strategy: Deconstructing the $37,000 Annual Cost

Understanding List Price vs. Net Price: The Reality of Patient and Payer Costs

The official list price, also known as the Wholesale Acquisition Cost (WAC), for Dupixent is $3,993.36 USD per carton as of January 3, 2025.¹⁵ This translates to an approximate annual WAC of $37,000.⁷ However, it is important to note that very few patients actually pay this list price.⁹ The average net price, which accounts for manufacturer discounts and rebates, was estimated by the Institute for Clinical and Economic Review (ICER) to be significantly lower, at $31,000.¹²

This inherent distinction between the publicly stated list price and the actual net price is a critical aspect of U.S. drug pricing. Private price negotiations and the application of rebates occur at various stages of the drug supply chain, directly influencing the actual revenue pharmaceutical manufacturers receive and the ultimate costs borne by payers.¹ The substantial discrepancy between Dupixent’s reported WAC and its estimated average net price highlights a fundamental lack of transparency within the U.S. drug pricing system. This difference, often referred to as the “spread,” is a product of complex, often confidential, negotiations involving manufacturers, distributors, Pharmacy Benefit Managers (PBMs), and insurers.² This intricate web of transactions makes it nearly impossible for individual patients, or even the broader public, to ascertain the true cost or value of a medication. Consequently, this opacity can foster mistrust among stakeholders and significantly complicate efforts to implement fair and effective drug pricing policies, as the actual financial flows and beneficiaries of these discounts remain largely hidden.²

Alignment with Value-Based Pricing: Cost-effectiveness, QALYs, and Societal Benefits

Dupixent’s pricing has been rigorously evaluated under value-based pricing principles, which advocate for aligning a drug’s cost with its therapeutic benefit and the patient outcomes it delivers.² ICER concluded that Dupixent’s expected net price of $31,000 is “well-aligned with the added benefit it provides to patients,” signifying that it represents a “good value for money”.¹²

Specifically, the incremental cost-effectiveness ratio (ICER) for Dupixent was estimated at approximately $101,800 per Quality-Adjusted Life Year (QALY) gained. This figure falls comfortably within the generally accepted “reasonable” value range in the U.S. for cost per QALY, which is typically cited as $50,000-$150,000.¹² This suggests that, from a health economic perspective, the price is justifiable given the health improvements it facilitates. Beyond direct health outcomes, Dupixent is projected to yield broader societal benefits. For patients with conditions like COPD, these benefits include an improved quality of life, reduced caregiving hours, and enhanced labor and non-labor productivity.¹⁴

While economic assessments indicate that Dupixent’s net price aligns with its value based on QALYs and broader societal benefits ¹², other evaluations describe similar drug pricing as “utterly unaffordable” and a “threat to public health”.¹⁹ This highlights a critical dichotomy: a drug can be scientifically and economically deemed “cost-effective” at an individual patient level, yet simultaneously remain “unaffordable” for the broader healthcare system or for individual patients, particularly those with limited insurance coverage or high out-of-pocket expenses. This suggests that current value-based pricing frameworks, while valuable for assessing clinical benefit and efficiency, may not fully capture the real-world financial burden or ensure equitable access. The problem, therefore, extends beyond the drug’s inherent value to the systemic capacity and willingness to pay for it, especially in healthcare systems with fragmented funding and high patient cost-sharing.

Competitive Landscape and Pricing Relative to Other Biologics

Despite its substantial price tag, Dupixent is positioned as a comparatively less expensive option within the high-cost biologic market for skin diseases. For instance, it costs less than other established biologics such as Humira and Enbrel, which are priced around $50,000 per year.⁷ This relative positioning contributes to Dupixent’s market acceptance as a more “affordable” choice within its therapeutic class.

A key factor influencing Dupixent’s sustained premium pricing is the current absence of significant biosimilar competition.¹⁰ This lack of competition is attributed to Dupixent’s novel mechanism of action and the inherent complexity of its manufacturing process.¹⁰ The entry of biosimilars typically serves as a powerful market force that drives down prices substantially.¹⁴ However, the market is not static. Future competition from similar investigational drugs, such as nemulixumab, is anticipated, which could exert downward pressure on Dupixent’s pricing.⁷

Dupixent’s current status of “relative affordability” compared to older biologics like Humira and Enbrel ⁷ is largely a function of its market timing and the ongoing absence of biosimilar competition.¹⁰ This implies that any assessment of its pricing as a “good model” is inherently precarious and time-bound. The long development timelines and substantial costs associated with developing biosimilars ¹⁴, coupled with robust patent exclusivity ²¹, effectively grant a temporary monopoly to the innovator drug. This allows for the maintenance of premium pricing for an extended period. The true measure of a “good model” would therefore need to account for how the drug’s price behaves post-patent expiry, as this is the point at which market competition is expected to drive significant price reductions.¹⁴ Consequently, a truly “good model” should inherently incorporate mechanisms or expectations for substantial price reductions after the period of exclusivity, rather than relying solely on the justification of initial value.

Key Table 1: Dupixent Pricing Overview (List vs. Net Price, Annual Cost)

This table provides a clear differentiation between the publicly stated list price and the estimated net price of Dupixent, along with comparisons to other biologics. This distinction is crucial for understanding the varying financial burdens placed on both individual patients and the broader healthcare system. By comparing Dupixent’s price to that of other established biologics, the table provides essential context, showing that while its cost is high, it is comparatively less expensive than some competitors, which is a key element of its market positioning and argument for relative value. This information serves as a foundational reference for further discussions on value-based pricing, R&D cost recovery, and patient access.

4. Drivers of High Drug Costs: The Case of Dupixent

Significant R&D Investments and the Role of Patent Exclusivity

Pharmaceutical companies, including Sanofi and Regeneron, the co-developers of Dupixent, undertake substantial research and development (R&D) investments to discover, develop, and bring new medications to market.² These expenditures encompass fundamental laboratory research, rigorous preclinical testing, extensive multi-phase clinical trials (for Dupixent, over 60 clinical studies involving more than 10,000 patients have been conducted across various indications), and navigating complex regulatory approval processes.² Sanofi’s financial reports indicate that its established product portfolio generates “enormous cash flows” necessary to fund the “average almost $1 billion in development costs per new drug”.²⁴ Furthermore, Sanofi’s R&D expenses increased by 11.8% in Q1 2024, reflecting a strategic allocation of resources towards development.²⁵

Patents are a cornerstone of intellectual property protection in pharmaceuticals, granting exclusive commercial rights for a specified period, typically 7-12 years after market entry, from an initial 20-year patent grant.² This exclusivity is intended to allow manufacturers to recoup their significant R&D investments and temporarily shield them from generic competition. Dupixent’s U.S. patent protection is projected to extend until at least 2031.²⁴ Beyond patents, regulatory exclusivity periods further restrict the FDA from accepting or approving generic drug or biosimilar applications, even if patent challenges occur.²²

The consistently cited high R&D costs and the imperative for recouping these investments are presented as primary justifications for the premium pricing of novel drugs.² Patent and regulatory exclusivity are the legal and regulatory mechanisms explicitly designed to provide this “innovation premium” by granting a temporary monopoly.²¹ However, the documented practice of “evergreening”—where manufacturers file new patents on minor modifications or secondary features to extend effective exclusivity beyond the original term ²¹—introduces a critical ethical and economic question. This practice raises concerns about whether the extended duration of this premium is genuinely justified by continued innovation or merely serves as a strategy to maintain market control and high prices, potentially delaying the entry of more affordable generic or biosimilar alternatives. This highlights a fundamental tension between incentivizing genuine pharmaceutical innovation and ensuring timely market competition for broader affordability.

Manufacturing Complexity of Biologics and its Cost Implications

Dupixent is classified as a biologic drug, meaning it is derived from living organisms or their components. This inherent characteristic typically renders biologics significantly more expensive to produce than chemically synthesized small-molecule drugs.⁹ The intricate and specialized manufacturing processes required for biologics contribute substantially to their higher cost. For instance, the development of a biosimilar (a highly similar version of a biologic) is “much more expensive to develop than generics” ($100-$300 million for a biosimilar versus $1-$2 million for a generic) and involves considerably longer development timelines (5-9 years for a biosimilar compared to approximately 2 years for a generic).¹⁴ This inherent manufacturing complexity is frequently cited as a primary reason why Dupixent has not yet encountered significant biosimilar competition ¹⁰, thereby allowing it to sustain its premium pricing in the market.

The high cost and significant complexity involved in the manufacturing of biologics like Dupixent create a formidable barrier to entry for potential biosimilar competitors.⁹ This implies that even upon the expiration of primary patents, the market for biologics does not experience the rapid and substantial price erosion that is characteristic of generic small-molecule drugs.¹⁴ This “biologic barrier” effectively prolongs the period during which innovator biologics can maintain high prices, challenging the conventional economic assumption that market forces will naturally lead to increased affordability over time. Consequently, this structural barrier suggests that a truly “good model” for drug pricing, particularly for biologics, might necessitate more direct policy interventions to foster earlier and more robust competition, rather than solely relying on patent expiration.

Market Access Strategies Beyond Pricing: Distribution and PBMs

Sanofi and Regeneron adopted an “unorthodox move” by directly negotiating the $37,000 price for Dupixent with insurers.⁷ This strategy was potentially employed to pre-empt or mitigate the kind of pricing pushback they had previously encountered with the approval of Praluent in 2015. The pharmaceutical supply chain is a complex network involving manufacturers, wholesale distributors, retail pharmacies, and Pharmacy Benefit Managers (PBMs).¹ Each entity within this chain contributes to costs and engages in various forms of price negotiations.¹ PBMs, acting on behalf of insurance companies, negotiate rebates and discounts, which can introduce layers of complexity and opacity to the final cost borne by the patient and payer.¹

Dupixent is primarily distributed through specialty pharmacies, which are equipped to handle medications requiring specific storage conditions, specialized handling, or close patient monitoring.⁹ In 2024, hospital pharmacies accounted for the largest share of Dupixent distribution (55.08%), driven by their role in administering biologics for severe conditions and favorable reimbursement structures for inpatient settings.¹³

The central role of PBMs in negotiating rebates and discounts effectively creates a “black box” within the drug supply chain where the actual net price of a medication is obscured.¹ While these negotiations can result in cost savings for insurers and other payers, these savings do not consistently or transparently translate into lower out-of-pocket costs for patients.¹ Furthermore, this system can inadvertently incentivize PBMs to favor higher-cost drugs that offer larger rebates ², potentially distorting market dynamics and undermining the selection of truly cost-effective therapies. This disconnect between the patient’s perceived cost and the drug’s negotiated value erodes transparency and can influence prescribing patterns. A “good model” for drug pricing would necessitate significantly greater transparency in these PBM negotiations and a clearer, more direct link between any negotiated savings and tangible reductions in patient affordability.

5. Ensuring Patient Access and Affordability: Dupixent’s Approach

Manufacturer Patient Assistance Programs (e.g., DUPIXENT MyWay)

Sanofi and Regeneron actively offer the DUPIXENT MyWay program, a multi-faceted initiative designed to support patient access. This program includes a Copay Card, which can reduce out-of-pocket copayments for commercially insured patients to as little as $0.¹⁵ Additionally, a Patient Assistance Program is available for eligible uninsured patients or those covered by Medicaid, with eligibility determined based on household income criteria.¹⁵ These programs are explicitly designed to help patients afford Dupixent and to assist them in navigating the often-complex insurance process, providing valuable support and educational resources.⁴

While manufacturer patient assistance programs like DUPIXENT MyWay are undeniably vital for ensuring individual patient access to high-cost therapies ¹⁵, they also carry a systemic implication. By directly subsidizing a portion of patient out-of-pocket costs, these programs effectively reduce the immediate financial burden on individuals, which can, in turn, dampen public outcry or political pressure regarding the high list prices of drugs. However, the underlying cost of the drug is still borne by the broader healthcare system (e.g., private insurers, government programs), and these programs are frequently not valid for federal programs like Medicare or Medicaid.¹⁵ This can shift the financial burden or create inequities among different patient populations. This raises critical questions about the long-term sustainability and ethical implications of relying on such programs as a substitute for systemic price reductions, potentially perpetuating a high-list-price, high-rebate model.

Insurance Coverage Dynamics: Commercial, Medicaid, and Medicare Out-of-Pocket Costs

The actual out-of-pocket costs for Dupixent patients vary considerably, influenced by their specific insurance coverage type (commercial, Medicaid, Medicare) and the individual plan’s details, such as deductibles and whether the medication is considered “preferred”.⁹

Commercial/Employer-Provided Insurance: Approximately 60% of commercially insured patients typically pay between $0 and $100 per month for Dupixent, while the remaining 40% incur monthly costs exceeding $100.¹⁵ It is common for insurers to implement “step therapy” requirements, mandating patients to demonstrate the ineffectiveness of cheaper alternative treatments before covering more expensive drugs like Dupixent.⁷
Medicaid: For the majority of individuals covered by Medicaid, the monthly out-of-pocket cost for prescription drugs like Dupixent ranges from $4 to $9.¹⁵
Medicare Part D: Approximately 79% of Medicare Part D beneficiaries can expect to pay between $0 and $100 per month for Dupixent, with 21% facing monthly costs exceeding $100.¹⁵ Eligible low-income beneficiaries may qualify for the Social Security Administration’s “Extra Help” program (Low-Income Subsidy or LIS), which can further reduce their monthly costs to $3-$9.¹⁵
Uninsured: Patients without any prescription drug insurance coverage typically face the full list price of Dupixent, in addition to any supplementary pharmacy charges.¹⁵

The stark variability in patient out-of-pocket costs across different insurance types vividly illustrates a fragmented and inequitable distribution of the financial burden associated with high drug prices.¹⁵ While certain patient segments benefit from robust insurance coverage and manufacturer assistance, a substantial portion, particularly those in high-deductible plans or lacking comprehensive insurance, continues to face significant financial hurdles. This fragmentation effectively obscures the true systemic cost of the drug and creates profound inequities in access, even for a medication deemed “value-aligned” by economic assessments. A truly “good model” for drug pricing would ideally strive for a more uniform, predictable, and equitable affordability across all patient populations, rather than relying on a complex and often confusing patchwork of assistance programs and disparate insurance benefits.

Key Table 2: Dupixent Patient Out-of-Pocket Costs by Insurance Type

This table directly translates abstract pricing discussions into the tangible financial burden experienced by patients, illustrating the real-world costs faced by individuals. By clearly delineating the different cost structures across various insurance types, the table starkly illustrates the existing disparities in healthcare access and affordability within the U.S. system. It provides crucial context for understanding the necessity and actual impact of manufacturer patient assistance programs, showing how these programs, while not a systemic solution, play a vital role in mitigating immediate costs for specific patient segments, thereby facilitating individual access. This data is invaluable for policymakers, healthcare executives, and patient advocates, as it clearly identifies where the most significant financial gaps and inequities exist, guiding the development of targeted interventions and policies aimed at ensuring more equitable access to essential medications.

Insurance Type	Typical Monthly Out-of-Pocket Cost Range	Percentage of Patients (where available)	Manufacturer Assistance Programs
Commercial/Employer-Provided	$0-$100 (60%), $100+ (40%)	60% pay $0-$100, 40% pay $100+	DUPIXENT MyWay Copay Card (as low as $0) ¹⁵
Medicaid	$4-$9	Most patients	DUPIXENT MyWay Patient Assistance Program ¹⁵
Medicare Part D	$0-$100 (79%), $100+ (21%)	79% pay $0-$100, 21% pay $100+	Social Security Administration’s Extra Help (LIS) ($3-$9) ¹⁵
Uninsured	Full list price ($3,993.36/carton) + pharmacy charges	N/A	DUPIXENT MyWay Patient Assistance Program (income-based eligibility) ¹⁵

Note: Costs can vary based on deductibles, preferred status of medication/pharmacy, and step therapy requirements.⁹

6. Economic and Societal Impact on the Healthcare System

Budgetary Impact Analysis and Healthcare Resource Utilization

Despite Dupixent’s price being assessed as aligned with its value (based on ICER’s cost-effectiveness analysis), ICER issued an “access and affordability alert”.¹² This alert stems from the concern that the aggregate short-term costs associated with Dupixent could impose a significant strain on healthcare budgets.¹² A budget impact analysis estimated an additional per-patient cost of approximately $18,400 over five years, even when considering the discounted net price of $31,000.¹²

The analysis further indicated that only about 5% of eligible patients could be treated without exceeding ICER’s budget impact threshold of $915 million at the discounted WAC.¹² This low proportion is partly attributed to Dupixent being a novel treatment in an area with few existing options, meaning it does not significantly displace current, potentially lower-cost, drug treatments.¹² While Dupixent has demonstrated its ability to reduce the use of other anti-asthmatic drugs, including oral corticosteroids (OCS), and potentially decrease asthma exacerbation-related hospital admissions, the overall healthcare costs can still increase substantially due to the high cost of the biologic drug itself.¹¹

The critical finding that a drug deemed “value-aligned” at an individual patient level (per ICER’s QALY assessment ¹²) can still trigger an “access and affordability alert” due to “budget strain” ¹² reveals a significant limitation in current health economic evaluation frameworks. This implies that even if a therapy is highly cost-effective for an individual patient, its aggregate impact on a healthcare system’s budget can become unsustainable if the eligible patient population is large. This highlights a fundamental disconnect: traditional cost-effectiveness analyses often focus on incremental costs per QALY, which may not adequately capture the total budgetary impact or the system’s capacity to absorb the cost of widespread adoption. A truly “good model” for drug pricing needs to reconcile individual patient value with system-wide affordability and sustainability, potentially through mechanisms like volume-based discounts, risk-sharing agreements, or more nuanced pricing for different indications that account for population size and budget impact.

Impact on Patient Quality of Life and Broader Social Outcomes

Beyond alleviating physical symptoms, Dupixent has been shown to profoundly enhance various aspects of patients’ everyday lives, including their mental health, social engagement, daily functioning, and leisure activities.³² Qualitative data indicates that participants reported significant reductions in stress, anxiety, depression, and the stigma associated with their condition, alongside increased happiness and improved ease in forming social and romantic relationships.³² For patients with skin of color, Dupixent has demonstrated improvements in specific concerns such as dyspigmentation (darker patches) and dry skin, which are unique clinical features in these populations.⁶ For individuals living with inadequately controlled COPD, Dupixent is anticipated to lead to fewer exacerbations, extended life expectancy, enhanced quality of life, increased labor and non-labor productivity, and a reduction in caregiving hours.¹⁴

The profound and multifaceted improvements in quality of life, mental well-being, social engagement, and productivity reported by Dupixent patients represent a significant societal return on investment that is often challenging to fully quantify within conventional health economic models like Quality-Adjusted Life Years (QALYs).¹⁸ While QALYs attempt to incorporate quality of life, the qualitative data suggests deeper, more holistic benefits that extend beyond direct clinical metrics into areas of social capital, personal fulfillment, and overall well-being. These broader societal impacts, such as reduced stigma, improved relationships, and increased participation in daily life, are difficult to assign a precise monetary value. A “good model” for drug pricing should strive to incorporate these broader, often unquantifiable, societal benefits more explicitly into its value assessments, perhaps through enhanced patient-reported outcomes measures, qualitative research, and broader social impact analyses, to provide a more comprehensive justification for premium pricing and to better inform resource allocation decisions.

Ethical Considerations in Balancing Innovation, Access, and Affordability

The high price of innovative drugs like Dupixent creates a persistent ethical dilemma: how to effectively balance pharmaceutical companies’ legitimate need for profitability (to incentivize ongoing research and development) with their fundamental social responsibility to ensure broad affordability and equitable access for all patients.² Critics argue that elevated drug prices, often sustained or exacerbated by extended patent protection (e.g., “evergreening” practices) and a lack of robust competition, can force patients into impossible choices between essential medication and other basic necessities.² This can lead to adverse health outcomes and exacerbate existing health inequities.

A particular challenge highlighted is the prevailing “one price fits all” approach for multi-indication drugs.³⁴ This rigid pricing model can result in a drug being deemed “not cost-effective” for certain indications, even if it offers significant clinical benefit, thereby limiting patient access for those specific uses.³⁵

The ethical tension between incentivizing pharmaceutical innovation and ensuring equitable patient access is significantly amplified by the prevailing “one price fits all” approach for drugs like Dupixent that treat multiple indications.³⁴ A drug may demonstrate exceptionally high value and cost-effectiveness for a severe, rare disease, but its value proposition might be comparatively lower for a more common, less severe condition. Maintaining a uniform high price across all indications, regardless of the differential value, can render the drug “not cost-effective” and thus inaccessible for patient groups suffering from indications where the value-to-cost ratio is lower.³⁵ This situation points to a clear ethical imperative for more flexible pricing models, such as indication-specific pricing.³⁴ Such models would allow the price to more accurately reflect the value delivered in each specific use case, thereby improving overall access and more effectively addressing health inequities by avoiding an “all or nothing” access decision that can exclude deserving patient populations.

Key Table 3: Dupixent Cost-Effectiveness Ratios (ICER/QALY) and Benchmarks

This table directly quantifies the “value” aspect of Dupixent’s pricing using widely accepted health economics metrics like ICER per QALY. It provides an objective, data-driven measure that moves beyond anecdotal observations to support the discussion on the drug’s economic justification. By presenting Dupixent’s ICER in relation to the established “reasonable” value range for QALYs in the U.S., the table allows for a direct and clear assessment of whether the drug’s price, from an economic perspective, is considered justified by the health benefits it delivers. The inclusion of different ICERs for varying disease severities highlights the inherent nuance in value-based pricing. It demonstrates that a drug might offer greater cost-effectiveness for a sicker patient population, which directly feeds into the broader discussion on the merits and challenges of implementing indication-based pricing. Explicitly noting the “access and affordability alert” despite favorable ICERs creates a direct and compelling link between individual-level cost-effectiveness and the potential population-level budget impact. This underscores a key, often overlooked, challenge in pharmaceutical economics: a drug can be “worth it” for an individual but still pose a significant financial burden on the overall healthcare system.

7. Evaluating Dupixent as a “Good Model” for Drug Pricing

Strengths: Value Alignment, Patient Support, and Innovation Incentives

Dupixent’s pricing model exhibits several notable strengths that contribute to its consideration as a potentially “good” example in certain respects.

Firstly, its value alignment is a significant factor. The net price of Dupixent has been assessed as aligning with commonly accepted cost-effectiveness thresholds in the U.S., with an ICER of approximately $101,800 per QALY, falling comfortably within the $50,000-$150,000 range.¹² This suggests that, for the significant health benefits it provides, the price is economically justifiable. Furthermore, its societal benefits extend beyond direct health outcomes, encompassing improved quality of life, enhanced productivity, and reduced caregiving burdens for patients and their families.¹⁴

Secondly, the robust patient support infrastructure provided by the DUPIXENT MyWay program is a commendable aspect. This comprehensive initiative, including copay cards and a patient assistance program, plays a crucial role in effectively mitigating out-of-pocket costs for a substantial number of commercially insured and eligible uninsured patients.¹⁵ This ensures that, despite a high list price, many patients can access the necessary therapy.

Thirdly, Dupixent’s pricing model supports innovation incentives. As a breakthrough biologic addressing conditions with significant unmet medical needs, its pricing allows its co-developers, Sanofi and Regeneron, to recoup their substantial R&D investments, which average approximately $1 billion per new drug.² This financial return serves as a vital incentive for continued innovation and investment in the complex and high-risk field of immunology.

While the identified strengths of Dupixent’s pricing model—its alignment with value, robust patient support, and effective innovation incentives—are undeniably significant, their “goodness” is often conditional and subject to specific interpretations. The concept of “value alignment” itself is based on a specific economic threshold (QALY), which is a metric that continues to be debated and refined. Patient support programs, while providing immediate relief for individuals, do not fundamentally address systemic affordability issues and can create a moral hazard by allowing high list prices to persist. Furthermore, while innovation incentives are necessary, they can also lead to practices like “evergreening” and prolonged market monopolies. This suggests that Dupixent’s model is “good” under a particular set of favorable conditions and perspectives, but its universal applicability as a “good model” for all drugs or for the entire healthcare system is limited without a more comprehensive approach to its inherent challenges.

Challenges: High List Price, Budget Strain, and Limited Competition

Despite its strengths, Dupixent’s pricing model presents several significant challenges that temper its suitability as a universally “good model” for drug pricing.

Firstly, the high list price and affordability concerns remain paramount. Even with the existence of a lower net price, the $37,000 annual list price (WAC) of Dupixent ⁷ represents a formidable barrier for uninsured patients and can lead to prohibitively high out-of-pocket costs for individuals with less comprehensive insurance coverage.¹⁵ The broader context of similar drug pricing has been described by experts as “utterly unaffordable” and a “threat to public health”.¹⁹

Secondly, the issue of budgetary strain is critical. Even if a drug is deemed “value-aligned” at an individual patient level, the aggregate cost of treating a large eligible patient population can impose significant strain on overall healthcare budgets, as clearly indicated by ICER’s budget impact analysis.¹² This highlights a critical disconnect between individual cost-effectiveness and the financial sustainability of the healthcare system as a whole.

Thirdly, limited competition for biologics is a persistent problem. The inherent complexity of biologic manufacturing processes, coupled with robust patent protection, means that Dupixent has not yet faced significant biosimilar competition.¹⁰ This lack of competition allows the drug to maintain its premium pricing for an extended period, contrasting sharply with the rapid and substantial price drops typically observed with the entry of generic small-molecule drugs.¹⁴

Finally, the ethical dilemmas of uniform pricing are evident. The prevailing “one price fits all” approach for multi-indication drugs can lead to situations where a drug is deemed “not cost-effective” for certain indications, thereby inadvertently limiting patient access despite potential clinical benefits for those specific uses.³⁵

The persistent challenges associated with Dupixent’s pricing—specifically its high list price, the strain it places on healthcare budgets, the limited competition it faces, and the ethical dilemmas arising from uniform pricing—collectively reveal an unresolved and fundamental tension within the pharmaceutical market. This tension exists between micro-level economic efficiency (i.e., the drug’s value per QALY for an individual patient) and macro-level equity and sustainability for the entire healthcare system. A pricing model that may be considered “good” for incentivizing innovation and providing individual patient benefit (even with assistance programs) can simultaneously be deeply problematic for public health budgets and for ensuring equitable access across diverse demographics. This implies that a truly “good model” for drug pricing cannot merely optimize for individual patient outcomes or manufacturer profitability; it must proactively address these macro-level systemic issues, rather than relying solely on reactive measures like patient assistance programs.

Lessons Learned and Recommendations for Future Drug Pricing Models

The analysis of Dupixent’s pricing model, particularly the challenges it highlights, strongly suggests the need for a fundamental paradigm shift in U.S. drug pricing policy. The current market-driven approach, while intended to foster innovation, has demonstrably fallen short in guaranteeing widespread affordability and equitable access, even for innovative, high-value drugs. The following recommendations point towards a necessary evolution from a system primarily dictated by unfettered market forces towards a more actively regulated framework. In this future model, “value” would not solely serve as a justification for premium prices, but rather as a dynamic factor that must be explicitly balanced with the imperatives of “affordability” and “access” through strategic and proactive policy interventions.

Embrace Value-Based Pricing with Refinements: While Dupixent demonstrates the potential of value-based pricing to align cost with clinical benefit, future models must be refined to incorporate a broader definition of “value,” including comprehensive societal benefits, and to explicitly address the aggregate budget impact.² This could involve more sophisticated outcomes-based contracts.²
Increase Transparency in the Supply Chain: Achieving greater transparency regarding net prices, rebates, and Pharmacy Benefit Manager (PBM) fees is paramount to fostering trust among stakeholders and enabling more informed policy decisions.¹ The Mark Cuban Cost Plus Drugs model, with its transparent cost-plus approach, offers a compelling alternative for certain drug categories.³⁹
Promote Timely Competition for Biologics: Policy interventions are necessary to facilitate earlier and more robust biosimilar entry into the market. This includes streamlining regulatory pathways, actively addressing “evergreening” practices that extend patent monopolies, and combating “perverse economic incentives” that may favor originator biologics over their biosimilar counterparts.¹⁴
Explore Indication-Specific Pricing: For multi-indication drugs like Dupixent, implementing indication-specific pricing could more accurately align the drug’s price with the value it delivers for each distinct use case.³⁴ This approach could significantly improve access for conditions where the drug offers substantial benefits but might be less economically impactful under a uniform pricing model. Successfully implementing this requires overcoming existing legislative and data collection barriers.³⁶
Strengthen Government Negotiation Powers: Legislative initiatives, such as the Inflation Reduction Act’s provisions for Medicare drug price negotiation ¹, represent crucial steps toward curbing high drug prices. However, their full impact and political longevity remain subjects of ongoing debate and uncertainty.⁴¹ Governments must recognize and leverage their inherent power to negotiate fair prices for public health.¹⁹
Prioritize Patient Affordability in Policy Design: While manufacturer-sponsored patient assistance programs provide essential support, systemic solutions are fundamentally required to ensure that high-value drugs are genuinely affordable for all patients, irrespective of their insurance status or socioeconomic background.²

Model Name	Description	Advantages	Disadvantages/Challenges	Applicability/Examples
Value-Based Pricing (VBP)	Links drug cost to therapeutic benefit, patient outcomes, and quality of life improvements.²	Broadens patient access, enhances affordability by mitigating financial risks, aligns price with real-world performance.²	Complex data sharing, operational complexities, difficulty in defining measurable outcomes, navigating diverse assessment frameworks.²	Innovative novel therapies with significant advantages (e.g., Dupixent’s ICER alignment).¹²
Cost-Plus Pricing	Price calculated by summing production costs (R&D, manufacturing, regulatory) plus a predetermined profit margin.²	Simplicity, transparency, ease of calculation, consistent return on investment.²	Disregards market demand/perceived value, can lead to suboptimal pricing (under/over), does not incentivize efficiency.²	Often favored by generic drug manufacturers (e.g., Mark Cuban Cost Plus Drugs).³⁹
Competitive-Based Pricing	Prices set in accordance with what competitors charge for similar products.²	Simplicity, straightforward implementation, swift market entry, can increase sales volume/market share.²	Missed profit opportunities if unique features exist, assumes competitors’ pricing is correct, can erode profit margins, does not incentivize innovation.²	Smaller to medium-sized pharmaceutical companies, highly competitive markets.²
International Reference Pricing (IRP)	Drug price in one country is set based on its price in other countries.²	Potential to significantly reduce overall national drug spending.²	May be seen as unfair by manufacturers, could stifle innovation, lead to delays in new drug launches in lower-priced markets.²	Many countries globally, proposed for Medicare in the US.²
Indication-Specific Pricing	Different prices for the same drug based on the specific disease or medical condition it treats.³⁴	Price accurately reflects value for each indication, potentially maximizes revenue while maintaining affordability for less critical uses.³⁴	Legislative/data collection barriers, administrative complexity, payer preference for uniform pricing.³⁴	Multi-indication drugs where therapeutic value varies significantly (e.g., Trastuzumab, Dupixent case studies).³⁶
Tiered Pricing	Adjusts drug prices based on the economic status of different markets or patient populations.³	Improves access in lower-income regions, balances financial sustainability with affordability needs.⁴⁷	Lack of transparency can lead to mistrust, risk of parallel trade, varied implementation approaches.⁴⁷	Global markets (LMICs), insurance formularies (Tier 1-4/5).²⁶
Subscription Models	Payers pay a fixed annual fee for unlimited access to a drug for a defined patient population.²	Offers budget predictability for payers, ensures broad access without per-patient cost constraints.²	Limited applicability (e.g., curative therapies), potential for overuse if not managed.²	Curative therapies (e.g., Hepatitis C).²
PBM Pricing (Spread vs. Pass-Through)	Spread: PBMs negotiate discounts, charge clients a higher price, keep the difference. Pass-Through: PBMs pass on all discounts, charge fixed admin fee.¹	Spread: PBMs profit. Pass-Through: Greater transparency for clients.²	Spread: Lack of transparency, can incentivize favoring high-rebate drugs. Pass-Through: Lower PBM revenue.²	US pharmaceutical supply chain.¹

8. Conclusion

In conclusion, the examination of Dupixent’s pricing model reveals a nuanced picture that prevents a simple categorization as a universally “good model” for drug pricing. Dupixent undeniably exemplifies successful pharmaceutical innovation, providing significant therapeutic benefits for a range of chronic inflammatory diseases and aligning with established value-based cost-effectiveness thresholds in the U.S..¹² The robust patient assistance programs offered by its manufacturers also play a crucial role in mitigating out-of-pocket costs for many patients, thereby facilitating access to this essential therapy.¹⁵ Furthermore, the premium pricing allows for the recouping of substantial R&D investments, which is vital for incentivizing continued innovation in the complex biopharmaceutical sector.²

However, the model is not without significant limitations when evaluated against the broader objectives of equitable access and systemic affordability. The persistent challenges include a high list price that creates substantial barriers for uninsured individuals, the considerable aggregate strain on healthcare budgets despite individual cost-effectiveness, the limited competition for biologics due to manufacturing complexity and extended patent protection, and the ethical dilemmas posed by a uniform pricing approach for multi-indication drugs.¹⁰ These issues highlight a fundamental tension between optimizing for individual patient value and ensuring the financial sustainability and equity of the overall healthcare system.

Therefore, while Dupixent’s model offers valuable lessons in innovation and targeted patient support, it underscores the critical need for a more comprehensive and balanced approach to drug pricing. A truly “good model” for the future must combine the essential incentives of market mechanisms with strategic, proactive regulatory interventions. This includes fostering greater transparency across the entire pharmaceutical supply chain, promoting timely and robust competition for biologics, actively exploring flexible pricing strategies such as indication-specific pricing to reflect differential value, and strengthening governmental negotiation capabilities. Such a multi-faceted approach is indispensable for cultivating a sustainable, transparent, and equitable drug pricing ecosystem that genuinely benefits all stakeholders, most importantly, the patients who rely on these life-transforming medicines.
