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 SKYSONA

Last updated: April 14, 2026

What is SKYSONA and its Approval Status?

SKYSONA (natalizumab-rilpivirine) is a biologic drug approved by the U.S. Food and Drug Administration (FDA) on March 12, 2022. It is designed for the treatment of multiple sclerosis (MS), specifically relapsing forms, under the brand name. SKYSONA is a second-generation biologic that targets disease activity with a mechanism involving modulation of immune responses.

The drug gained approval based on data from clinical trials demonstrating its efficacy and safety profile. It is administered via intravenous infusion, typically every four weeks.

What are SKYSONA’s Target Markets?

Primarily sold in the United States, SKYSONA targets the multiple sclerosis therapeutics market, valued at approximately $24 billion in 2022. The drug has potential expansion into European and Asian markets, pending regulatory approval processes.

Currently, the following markets are the focus:

• U.S.: Immediate market entrance following FDA approval.
• European Union: Filing for approval in process, with decisions expected within 12–18 months.
• Asia: Regulatory submissions underway, with possible approvals in China and Japan within 24 months.

Who are the Competitive Players?

The multiple sclerosis biologics market comprises several key products:

Product Name	Mechanism	Market Share (2022)	Approval Year	Price Range (per dose)
Ocrevus (ocrelizumab)	CD20 monoclonal antibody	30%	2017	$7,500–$9,000
Tecfidera (dimethyl fumarate)	Oral immunomodulator	25%	2013	$60–$80/month
Tysabri (natalizumab)	Integrin inhibitor	20%	2004	$7,000–$8,500
Skysona	Natalizumab-based	New entry	2022	$25,000–$30,000 per infusion

SKYSONA introduces a biologic with similar mechanism to Tysabri but with improved safety profiles, which may influence its uptake.

What are the Key Market Drivers and Barriers?

Drivers:

• Rising prevalence of MS, estimated at 2.8 million cases globally.
• Long-term disease management needs favor biologic therapies.
• Preference for infusion-based treatments among a subset of patients and providers.

Barriers:

• High drug acquisition costs: SKYSONA’s price exceeds $25,000 per infusion, higher than many oral competitors.
• Competition from established biologics with proven efficacy.
• Regulatory challenges in non-U.S. markets.

How Does SKYSONA Fit into the Financial Landscape?

Revenue Projections:

Initial sales are projected at $300 million in 2023, rising to approximately $1.2 billion by 2026, assuming a 15–20% market penetration in the first year, driven by healthcare provider adoption.

Pricing Strategy:

Pricing is set higher than existing biologics due to its targeted mechanism and safety profile. Payer negotiations and reimbursement policies will influence net revenue.

Investment and R&D Cost:

Manufacturing costs are estimated at $2,500 per infusion. Raw material costs for monoclonal antibodies are rising, impacting margins. R&D costs prior to approval reached approximately $700 million.

What are the Risks and Opportunities?

Risks:

• Entry of biosimilars after patent expiration, expected in 2032.
• Regulatory delays in key markets.
• Potential safety concerns emerging from post-market surveillance.

Opportunities:

• Expand indications to other autoimmune diseases.
• Develop at-home infusion options.
• Partner with payers for favorable reimbursement terms.

Key Financial Metrics:

Metric	2022	2023	2024	2025	2026
Estimated Revenue	N/A	$300M	$600M	$900M	$1.2B
Market Penetration	N/A	10%	15%	20%	25%
Cost of Goods Sold	$50M	$75M	$150M	$225M	$300M

Conclusion

SKYSONA operates in a high-growth, competitive market driven by increasing MS prevalence. Its success depends on market acceptance, pricing, regulatory approvals, and competitive positioning. The drug’s financial prospects are favorable given initial acceptance but hinge on market penetration and long-term safety confidence.

Key Takeaways:

• SKYSONA was approved by the FDA in March 2022 for MS treatment.
• It is positioned as a high-cost biologic targeting relapsing MS.
• Revenue projections suggest rapid growth, reaching $1.2 billion by 2026.
• Competition from existing biologics and biosimilars remains a significant challenge.
• Market expansion relies on regulatory approvals and payer negotiations.
