Note on Biologic Patents

Matching patents to biologic drugs is far more complicated than for small-molecule drugs.

DrugPatentWatch employs three methods to identify biologic patents:

1. Brand-side disclosures in response to biosimilar applications

These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

2. DrugPatentWatch analysis and company disclosures

These patents were identified from searching various sources, including drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

3. Patents from broad patent text search

For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

Market Dynamics and Financial Trajectory for the Biologic Drug: DARZALEX

Last updated: November 7, 2025

Introduction

DARZALEX (daratumumab) has emerged as a pivotal therapy in the treatment landscape of multiple myeloma, transforming how clinicians approach this hematologic malignancy. As a monoclonal antibody targeting CD38, DARZALEX’s innovative mechanism of action has influenced both clinical practices and pharmaceutical market strategies. This analysis examines the current market dynamics, growth drivers, competitive landscape, regulatory environment, and projected financial trajectory of DARZALEX within the broader biologics sector.

Market Overview and Therapeutic Positioning

Since its FDA approval in 2015 for relapsed/refractory multiple myeloma (RRMM), DARZALEX quickly gained prominence due to its demonstrated efficacy and tolerable safety profile. It is now approved across multiple lines of therapy, including frontline settings in combination with standard regimens, broadening its market reach. According to IQVIA data, the drug’s sales surged, reflecting its rapid adoption by hematologists and oncologists worldwide.

The multiple myeloma treatment landscape remains highly dynamic, characterized by increasing diagnosis rates driven by aging populations and improved detection techniques. The disease's chronic nature necessitates long-term management strategies, often involving combination therapies incorporating DARZALEX, which enhances its market penetration.

Market Drivers

1. Expanding FDA Approvals and Label Extensions

Recent regulatory milestones have significantly expanded DARZALEX's indications:

• Frontline Combination Therapies: Approved in combination with lenalidomide and dexamethasone (Rd), and with bortezomib, melphalan, and prednisone (VMP) for newly diagnosed multiple myeloma in eligible patients.
• Maintenance Therapy: Utilization as a maintenance therapy post-autologous stem cell transplant (ASCT) underlines its role beyond refractory settings.

These approvals serve as strong growth catalysts, facilitating broader clinical adoption.

2. Evolving Standard of Care

DARZALEX's incorporation into first-line regimens has shifted the standard of care, positioning it as a cornerstone in multiple myeloma management. Such integration enhances revenue streams and supports sustained demand.

3. Market Penetration in International Territories

While the majority of sales remain concentrated in North America and Europe, emerging markets exhibit increasing adoption due to expanding healthcare infrastructure and rising disease awareness. Strategic partnerships with regional distributors accelerate this growth.

4. Combination Therapy Development

The ongoing clinical pipeline explores novel combinations—such as DARZALEX with CAR-T therapies and other immunomodulators—that aim to improve response durability. Positive trial outcomes could redefine treatment paradigms and further expand market opportunities.

Competitive Landscape

DARZALEX faces competition from other anti-CD38 monoclonal antibodies, including isatuximab (Sanofi) and elotuzumab (AbbVie), though DARZALEX’s early market entry and robust clinical data confer a competitive advantage. Additionally, emerging therapies such as BCMA-targeted CAR T-cells and bispecific antibodies threaten to reshape the treatment landscape.

However, DARZALEX’s versatility—used in multiple combination regimens and across multiple lines—fortifies its market position. Its proven efficacy, especially when combined with immunomodulatory drugs and proteasome inhibitors, sustains its dominance.

Regulatory Environment and Patent Position

Patent protected until 2026–2028 in key markets, DARZALEX benefits from exclusivity that supports premium pricing. However, biosimilar contenders are anticipated to enter markets post-patent expiry, potentially exerting downward pressure on prices and margins.

Regulatory agencies continue to review expanded indications, with data from ongoing trials reinforcing its approval portfolio. Investment in post-marketing studies maintains its scientific and commercial relevance.

Financial Trajectory and Revenue Projections

Historical Performance

Since its launch, DARZALEX has demonstrated exponential revenue growth. Takeda Pharmaceuticals reported approximately $6.1 billion in global sales for FY2022, marking it as one of the top-selling monoclonal antibodies [1]. The robust sales increase is attributed to expanded indications, combination regimens, and global uptake.

Forecasted Growth Trends

Industry analysts project compounded annual growth rates (CAGRs) of approximately 15-20% until 2027. Key factors supporting this include:

• Continued approval of new indications, especially upfront in newly diagnosed patients.
• Introduction of DARZALEX protocols in maintenance therapy, which sustains revenue over extended periods.
• Growing prevalence and diagnosis rates of multiple myeloma globally.

Impact of Biosimilar Competition

Post-patent expiration, biosimilar entrants could fragment sales, pressuring prices and margins. Nonetheless, strong brand loyalty and clinical advantages may mitigate immediate declines. Strategic initiatives, such as value-based pricing and diversified combinations, will be crucial for maintaining revenue streams.

Market Outlook by Region

• North America: Expected to remain the largest market, supported by high disease prevalence and established healthcare infrastructure.
• Europe: Steady growth anticipated as regulatory approvals increase and clinical practices align.
• Emerging Markets: Rapid growth potential exists, albeit hindered temporarily by affordability and healthcare access barriers.

Strategic Opportunities and Challenges

Opportunities

• Innovation in Combination Regimens: Combining DARZALEX with novel agents could unlock new patient populations.
• Biomarker Development: Precision medicine approaches may optimize patient selection and treatment outcomes.
• Global Expansion: Targeted market entry strategies in Asia-Pacific and Latin America could significantly increase sales.

Challenges

• Pricing and Reimbursement Pressures: Cost-containment strategies may affect margins.
• Competitive Landscape: New modalities such as bispecific T-cell engagers and CAR T-cell therapies threaten to supplant monoclonal antibodies.
• Post-Patent Biosimilar Entry: Will necessitate price adjustments and market repositioning.

Conclusion: Market Dynamics and Forward-Looking Financials

DARZALEX’s trajectory exemplifies the dynamic nature of biologic oncology therapeutics. Its rapid market adoption, expanding indications, and strategic positioning underpin a robust revenue outlook. The product’s success hinges on ongoing clinical development, geographic expansion, and navigating competitive pressures. While biosimilar competition presents risks, DARZALEX’s entrenched position as a treatment mainstay suggests sustained profitability, especially if lifecycle management strategies are effectively executed.

In a landscape marked by innovation—and imminent patent cliffs—stakeholders must remain agile. Prioritizing clinical pipeline advancements, forging strategic partnerships, and optimizing pricing strategies will be vital for maintaining long-term growth.
