What are the top-selling drugs of MallInckrodt?

Overview of Mallinckrodt PharmaceuticalsCompanyny History and Market Position
Mallinckrodt Pharmaceuticals is a long‐standing global specialty pharmaceutical company with a history spanning more than 155 years. Historically known for its pioneering role in the pharmaceutical sector, the company has evolved through numerous strategic shifts, financial restructurings, and regulatory challenges. Over its storied history, Mallinckrodt has built a reputation for addressing unmet medical needs with innovative therapies in complex treatment landscapes. Its market position has been defined by a diversified portfolio that comprises both branded specialty therapies and vertically integrated specialty generics, making it a key player in the global pharmaceutical arena.

Following several bankruptcy filings and restructuring processes—including its Chapter 11 proceedings and Irish examinership—the company has emerged with an enhanced balance sheet and renewed strategic focus. With its headquarters located in Ireland, yet predominantly operating in the United States, Mallinckrodt continues to maintain an influential market presence through its integrated manufacturing capabilities, broad product portfolio, and strategic positioning in niche therapeutic areas. This dual-market approach allows the company to benefit from both high-quality U.S.-based production and favorable tax positioning, supporting ongoing investments in research, development, and market expansion.

Product Portfolio
Mallinckrodt’s portfolio is broadly divided into two key segments: Specialty Brands and Specialty Generics.

•  The Specialty Brands segment is at the forefront of innovation and is centered on high-value, proprietary therapies that address severe and critical conditions. Within this segment, the company focuses on therapies that target autoimmune and rare diseases, neurology, rheumatology, hepatology, nephrology, pulmonology, and oncology, among others. The portfolio includes flagship products such as Acthar Gel (repository corticotropin injection), which has been recognized as a groundbreaking therapy for various inflammatory and autoimmune disorders, and Terlivaz® (terlipressin), which is specifically designed for patients with hepatorenal syndrome—a life‐threatening condition affecting kidney function. Additional assets in the specialty brands include INOmax® and its next-generation delivery system INOmax EVOLVE™ DS, as well as the Therakos® immunology platform, although the latter has recently been part of strategic divestitures.

•  The Specialty Generics segment complements the brand portfolio by delivering high-quality generic drugs and active pharmaceutical ingredients (APIs). This segment has been instrumental in ensuring a reliable, consistent supply of medications to mitigate market disruptions, particularly in light of recent supply chain challenges and pricing pressures across the industry. It also includes controversial segments historically linked to opioid products, which have played a substantial role in the company’s revenue mix but have also been at the center of regulatory and litigation challenges.

Top-Selling Drugs

Identification of Leading Products
When discussing Mallinckrodt’s top-selling drugs, two products stand out as the cornerstones of its Specialty Brands portfolio: Acthar Gel (repository corticotropin injection) and Terlivaz® (terlipressin).

•  Acthar Gel (repository corticotropin injection):
Acthar Gel has historically been the flagship product for Mallinckrodt. It is indicated for the treatment of a variety of autoimmune and inflammatory disorders, including multiple sclerosis relapses, infantile spasms, and conditions involving severe inflammation. Acthar Gel’s unique mechanism, which involves stimulation of endogenous corticosteroid production, has allowed the product to capture a significant share of the market. Notably, Acthar Gel has delivered robust revenue figures over the years, with reports indicating that it generated sales in the vicinity of $593 million in the previous year. Its strong performance has made Acthar Gel synonymous with Mallinckrodt’s brand identity—it is frequently referenced in discussions about high-priced specialty therapies and has been a pivotal contributor to the company’s overall net sales. However, this top-selling status has come with challenges, particularly around competitive pressures, pricing scrutiny, and regulatory debates regarding its clinical profile.

•  Terlivaz® (terlipressin):
Terlivaz is another major pillar in Mallinckrodt’s portfolio, representing the company’s focused efforts to address life-threatening conditions such as hepatorenal syndrome (HRS) in adults. As the only FDA-approved therapy for improving kidney function in HRS, Terlivaz has experienced rapid uptake in hospital formularies and has garnered significant interest from the medical community due to its distinct clinical benefits. In its launch phase, the product managed to achieve approximately 50% of targeted hospital formulary access, which underscores both its clinical value and market acceptance, despite being a relatively new entrant compared to the well-established Acthar Gel. Clinically, Terlivaz’s differentiation lies in its ability to reverse renal dysfunction rapidly—a critical need in patients with HRS, offering a potential lifeline in conditions marked by rapid deterioration.

Additionally, while not always counted among the “top-selling” products from a revenue standpoint, other drugs such as INOmax® EVOLVE™ DS and the formerly owned Therakos® platform have played important roles in the overall revenue mix. INOmax EVOLVE™ DS, for instance, represents the next generation of the company’s nitric oxide delivery systems and is positioned to contribute more substantially in future financial results, while the divestiture of Therakos® indicates strategic prioritization towards core high-selling brands.

Sales Data and Revenue Analysis
A detailed examination of sales figures reveals that Acthar Gel consistently ranks as the highest revenue generator for Mallinckrodt. According to published financial reports, Acthar Gel contributed approximately $593 million in sales in the previous year, reflecting its entrenched position as a high-ticket, high-demand product. These figures not only underscore the product’s market dominance but also highlight the complexity involved in its pricing and reimbursement strategies—a subject that has drawn substantial scrutiny from both regulators and competitors.

In contrast, Terlivaz, although in an earlier phase of market penetration, has demonstrated promising initial results. For example, in the first quarter of 2023, financial disclosures indicated that the launch of Terlivaz had exceeded initial expectations, with significant formulary inclusion in target hospitals and strong engagement from healthcare providers. Projections suggest that if current momentum is maintained, Terlivaz could ultimately achieve annual peak sales in the range of $200 million to $300 million. This rapid adoption is particularly noteworthy given the challenges associated with introducing a new drug in a highly regulated therapeutic area and the ongoing emphasis on returning to sustainable growth post-restructuring.

It is also important to note that the overall revenue contribution from the Specialty Brands segment—which includes these top-selling drugs—has been subjected to both favorable trends and competitive headwinds. For instance, while the launch of Terlivaz has provided a significant boost towards formulary growth and represents an important new growth vector, the performance of Acthar Gel has experienced fluctuations due to increased competition, market scrutiny, and evolving shifts in payer policies. Detailed analyses of quarterly results, such as those from the second and third quarters of 2023, illustrate that even as net sales have experienced modest growth in certain quarters, the long-term trajectory for these high-value drugs remains promising despite temporary setbacks.

Moreover, the sales data for other assets in Mallinckrodt’s portfolio, such as the Specialty Generics segment, have also been examined, and while these generics contribute to overall revenue stability, they generally do not match the magnitude of revenue generated by flagship products like Acthar Gel and Terlivaz. This underscores the reliance on a few high-impact products that are critical to Mallinckrodt’s financial performance and strategic planning.

Market Dynamics

Competitive Landscape
The competitive landscape in which Mallinckrodt operates is multifaceted, impacting the top-selling drugs in several key dimensions. The market for high-priced specialty therapies is intensely competitive, with several factors shaping the performance of products like Acthar Gel and Terlivaz.

•  For Acthar Gel, competition arises not only from within the pharmaceutical industry but also in the form of increasing payer and regulatory scrutiny over drug pricing. The high cost associated with Acthar has led to debates within the healthcare sector and among policymakers, particularly as competitors develop alternative therapies that offer similar clinical benefits at a potentially lower cost. Moreover, the scrutiny over pharmaceutical spending in the specialty space has put additional pressure on Mallinckrodt, with competitors actively marketing next-generation biologics and alternative treatments that could erode Acthar Gel’s market share over time.

•  On the other hand, Terlivaz is distinguished by its status as the first and only FDA-approved drug specifically indicated to improve kidney function in adults with hepatorenal syndrome. This unique positioning, coupled with strong clinical trial data and rapid formulary uptake, gives Terlivaz a competitive edge in a market segment that is relatively unencumbered by direct comparators. Nevertheless, the landscape is dynamic; emerging therapies, generic competition, and potential regulatory changes all represent factors that could influence Terlivaz’s future sales performance once its market presence becomes more established.

In addition to direct product competition, broader market forces also play a significant role. The company's overall strategic repositioning—involving sales consolidation and asset divestitures (such as the sale of Therakos to CVC Capital Partners for $925 million)—is partly driven by the need to streamline its product offerings and focus resources on high-potential, high-market-impact drugs. This repositioning is essential to remain competitive in a market where pricing pressures, rapid innovation, and regulatory mandates are continuously reshaping the competitive environment.

Factors Influencing Drug Sales
Multiple factors influence the sales of Mallinckrodt’s top-selling products, both at the micro and macro levels. Key determinants include:

•  Regulatory Environment and Approvals:
The ability to secure regulatory approvals, such as the FDA’s acceptance of supplemental New Drug Applications (NDAs) or the expedited review processes for drugs like Terlivaz, can substantially enhance market access and sales performance. Regulatory milestones not only validate the safety and efficacy of the products but also drive increased confidence among prescribers and payers, thereby impacting their adoption rates. For example, Terlivaz's FDA approval—coupled with its demonstrated clinical benefits—has played an instrumental role in its rapid formulary inclusion in hospitals.

•  Formulary Access and Healthcare Provider Engagement:
For specialty products, hospital formulary inclusion is critical. Terlivaz’s impressive early penetration (capturing approximately 50% of the targeted hospital formulary access, as reported in Q1 and Q2 results) illustrates the importance of healthcare provider engagement and early adoption in driving sales growth. Similarly, extensive real-world data supporting the clinical benefits of Acthar Gel has contributed to its longstanding dominance in formulary decisions, despite being subject to increased scrutiny.

•  Pricing and Reimbursement Dynamics:
The pricing of specialty pharmaceuticals is among the most debated topics in healthcare policy. Acthar Gel, for instance, has been noted for its high price and the resulting pressure from payers and regulators to justify its cost relative to its clinical benefits. Changes in reimbursement practices, legislative initiatives, and shifts in payer policies can significantly alter the revenue dynamics of these drugs. In an environment of increasing pricing pressure, maintaining market share and ensuring broad reimbursement become essential factors that directly impact sales performance.

•  Market and Competitive Pressures:
Competitive pressures, including the entry of generic alternatives and new innovative therapies, constantly influence the sales trajectory of top-selling drugs. The Specialty Generics segment, which is designed to provide a stable supply of high-quality medications, even as it faces price competition and market saturation, indirectly supports the company’s revenue structure by mitigating the risks associated with high-priced specialty drugs. Additionally, the company’s ongoing restructuring and debt-reduction strategies have also played a role in shaping market dynamics by potentially freeing up capital for further investments in innovation and market expansion.

•  Litigation and Financial Restructuring:
Historical and ongoing litigation, particularly around the opioid crisis and regulatory challenges related to pricing and marketing practices, have had a profound impact on the company’s financial landscape. Acthar Gel’s pricing and the aggressive marketing practices used in some of the company’s opioid products have attracted significant legal attention and settlements. These legal challenges, while not directly influencing the clinical value of the drugs, have an effect on investor perception and strategic capital allocation, which in turn can influence long-term sales strategies and market positioning.

Future Outlook

Potential Growth Areas
Looking to the future, several key growth areas are anticipated to drive Mallinckrodt’s long-term success.

•  Expansion of Terlivaz’s Market Penetration:
Given its unique indication and the robust clinical data supporting its efficacy in treating hepatorenal syndrome, Terlivaz is poised for significant growth. With the product already achieving rapid formulary penetration in target hospitals and demonstrating clear clinical benefits, its potential to capture additional market share remains strong. Market projections indicate that Terlivaz could eventually generate annual peak sales in the range of $200 million to $300 million, making it a central growth pillar for the company. The continued expansion of hospital access and integrated marketing strategies aimed at informing physicians and payers about its benefits are crucial to its sustained growth.

•  Innovative Product Launches and Pipeline Advancement:
The future outlook for Mallinckrodt is not solely reliant on its current top-sellers. The company is actively advancing other innovative therapies, such as the rollout of the INOmax EVOLVE™ DS delivery system. Although not yet at the level of a top-selling drug, the successful deployment of such innovative delivery systems represents an opportunity to enhance market relevance and diversify revenue streams. Furthermore, the anticipated launch of an Acthar Gel Single-Dose Pre-filled SelfJect™ Injector represents another strategic initiative designed to improve product usability, patient compliance, and ultimately reinforce the market position of Acthar Gel.

•  Growth in Specialty Generics:
While the focus is often on the high-profile branded products, the Specialty Generics segment offers a steady and reliable revenue stream. This segment is critical in providing stable cash flows amidst market uncertainties and has achieved consecutive quarters of double-digit net sales growth in recent periods. The reliability of U.S.-manufactured generic products, combined with the company’s expertise in navigating supply chain challenges, supports the overall financial health of Mallinckrodt and creates opportunities for reinvestment in high-potential areas.

•  Strategic Collaborations and Divestitures:
The company’s recent strategic moves, including the divestiture of assets such as Therakos®, are aimed at reducing net debt and reallocating resources towards its core high-selling drugs. These strategic moves not only strengthen the balance sheet but also enable a more focused approach towards innovative therapies with high market potential. By streamlining its portfolio and focusing on key drivers of revenue, Mallinckrodt is positioning itself for long-term growth amid a challenging competitive backdrop.

Challenges and Opportunities
Despite these growth prospects, Mallinckrodt faces several challenges that could impact the long-term trajectory of its top-selling drugs, as well as the overall success of its portfolio.

•  Regulatory and Pricing Pressures:
Both Acthar Gel and Terlivaz are subject to intense regulatory scrutiny. Acthar Gel, in particular, faces significant challenges related to pricing pressures and payer negotiations that can affect its market access and reimbursement levels. Legislative and regulatory developments aimed at curbing high drug prices may lead to adjustments in pricing strategies, potentially impacting revenue. Terlivaz, despite its promising clinical profile, must continue to navigate complex regulatory pathways to maintain its competitive edge.
