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 DARZALEX FASPRO

Last updated: February 20, 2026

DARZALEX FASPRO (daratumumab and hyaluronidase-fihj) is a subcutaneous formulation of Darzalex, the monoclonal antibody used to treat multiple myeloma. It received approval from the FDA in August 2020, offering an alternative to the intravenous form. The drug's market evolution depends on demand, competitive landscape, regulatory factors, and pricing.

Market Position and Adoption

DARZALEX FASPRO benefits from several factors:

• Patient Convenience: Subcutaneous administration reduces infusion time from hours to a few minutes.
• Clinical Efficacy: Comparable or superior outcomes in combination therapies.
• Physician Preference: Ease of use encourages adoption primarily in the U.S. and developed markets.

Market penetration is tied to its approval for multiple indications:

• Newly diagnosed multiple myeloma (NDMM) in combination with other agents.
• Relapsed/refractory multiple myeloma (RRMM).

In 2022, DARZALEX FASPRO's sales surpassed $1.1 billion globally, with rapid growth projected as adoption expands.

Competitive Landscape

Primary competitors include:

• Isatuximab (Sanofi): Approved as a subcutaneous treatment for RRMM.
• Elotuzumab (Eloctar): Used in combination therapies.
• IV formulations of DARZALEX: Still prevalent, but declining as FASPRO gains market share.

Market share has shifted, with FASPRO capturing approximately 40% of daratumumab-related sales by 2022, driven by preference for its injection method.

Pricing and Reimbursement

Pricing impact is a key factor:

• Cost per dose: Approximately $4,500 for FASPRO, comparable to IV formulations but with savings in administration costs.
• Reimbursement policies favor outpatient settings and quick administration, reducing overall treatment costs.

In the U.S., payers increasingly favor subcutaneous formulations, influencing insurance coverage and patient access.

Regulatory and Clinical Development

Key milestones:

• FDA approval: August 2020.
• EMA approval: September 2020.
• Ongoing Phase III studies aim to support expanded indications, promising further revenue streams.

Financial Performance and Projections

Year	Estimated Global Sales (USD billions)	Growth Rate	Comments
2022	1.1	N/A	First full year post-launch
2023	1.35	22.7%	Driven by increased adoption
2024	1.65	22.2%	Broader label approvals; expanded indications

Revenue growth is driven by:

• Expansion in first- and second-line therapy settings.
• Global rollout beyond the U.S.
• Competitive positioning with subcutaneous formulations.

Operating margins benefit from the streamlined administration process, reducing healthcare resource utilization.

Risks and Uncertainties

• Market competition: New agents or biosimilars could erode market share.
• Regulatory challenges: Delays or restrictions could limit expansion.
• Pricing pressures: Payers could push for discounts, impacting revenue.

Key Takeaways

• DARZALEX FASPRO has secured a significant market share in multiple myeloma treatment due to convenience and clinical efficacy.
• Sales are expected to grow at double-digit rates through 2024, supported by label expansion and global adoption.
• Competition from other monoclonal antibodies and biosimilars poses a threat to sustained market dominance.
• Reimbursement dynamics favor subcutaneous formulations, contributing to revenue growth.
• The financial trajectory relies on continued clinical success and market acceptance in emerging regions.
