What is the Drug Associated with NDC 65862-0626?
NDC 65862-0626 refers to Sparsentan (Filspari), approved by the FDA in November 2021. It is indicated for the treatment of adults with primary or secondary (diabetic or other) focal segmental glomerulosclerosis (FSGS). Sparsentan is an oral, dual endothelin receptor and angiotensin II receptor blocker, marketed by Travere Therapeutics.
Market Landscape & Competitive Position
Market Size and Patient Population
- The prevalence of FSGS in the U.S. is estimated at 1–3 cases per 100,000 population.
- The total number of diagnosed FSGS patients in the U.S. is approximately 6,000–15,000.
- Not all patients are eligible for or will receive Sparsentan; treatment penetration is expected to be moderate initially due to the condition's rarity and specialized indication.
Key Competitors
- No FDA-approved therapies directly target FSGS; however, off-label use of drugs like corticosteroids, calcineurin inhibitors, and other immunosuppressants occurs.
- Immunosuppressants (e.g., corticosteroids, cyclophosphamide) serve as off-label treatments with variable efficacy.
- Trials for other FSGS drugs include OSP-101 by Omeros, Budesonide, and experimental therapies, but none has secured approval comparable to Sparsentan.
Market Entry Factors
- Pricing will influence market penetration and reimbursement.
- Approval in additional indications (e.g., other glomerular diseases) could expand market size.
- Off-label use and physician familiarity with existing therapies may slow uptake initially.
Price Projections & Revenue Estimates
Current Pricing and Reimbursement Considerations
- Folded into similar orphan drugs, initial wholesale acquisition cost (WAC) estimates range between $10,000 and $15,000 per month.
- Estimated annual therapy cost per patient: $120,000 to $180,000.
- Payers may negotiate rebates, affecting net prices.

Revenue Drivers
- Prescriber adoption rate escalation.
- Expansion into secondary indications.
- Reimbursement policies favoring innovative orphan drugs.
Price Sensitivity
- If competitive therapies emerge or generics are introduced, prices may decline by 20-30%.
- Payer negotiations and risk-sharing agreements influence actual revenues.
Regulatory and Policy Impact
- Orphan drug designation provides incentives like market exclusivity (7 years in the U.S.), affecting pricing power.
- Medicaid rebate policies and Medicare/Medicaid coverage decisions shape net revenue.
Risks and Uncertainties
- Slow adoption due to the rarity of FSGS.
- Potential emergence of alternative treatments or biosimilars.
- Reimbursement challenges in the short term.
Key Takeaways
- NDC 65862-0626 (Sparsentan) addresses a niche, with a projected U.S. market size of up to 15,000 patients.
- Initial price points likely range between $120,000 and $180,000 annually per patient.
- Market revenues could reach approximately $3 billion by 2025, assuming gradual adoption and pricing stability.
- Competitive landscape remains limited but could change with new entrants or expanded indications.
- Payer dynamics and regulatory protections significantly influence pricing and revenue potential.
FAQs
1. What factors influence the initial price of Sparsentan?
Regulatory exclusivity, orphan drug status, development costs, and payer negotiations determine initial pricing levels.
2. How does Sparsentan's market size compare to other orphan drugs?
It is smaller; most orphan drugs target diseases affecting fewer than 100,000 Americans, but the niche nature of FSGS limits potential market size.
3. What are the key barriers to market penetration?
Limited awareness among physicians, off-label competition, and reimbursement hurdles are primary barriers.
4. How might future approvals or indications affect revenue?
Approval for additional glomerular diseases could expand the market, boosting revenue potential significantly.
5. What measures could impact pricing in the coming years?
Introduction of biosimilars, regulatory changes, or patent expirations could lead to price erosion.
