What is NDC 00832-6054?
NDC 00832-6054 corresponds to Ampyra (dalfampridine) extended-release tablets, approved by the FDA in 2010 for improving gait in multiple sclerosis (MS) patients. The drug's primary indication is to enhance walking speed and mobility in MS patients who have difficulty walking. It is marketed by Acorda Therapeutics.
Market Size and Competition
Market Scope
- Global multiple sclerosis (MS) prevalence is estimated at approximately 2.8 million cases, with the U.S. accounting for nearly 1 million.
- The US MS drug market was valued at about $4 billion in 2022 (MarketWatch, 2022).
- Ampyra’s specific segment is estimated at $300 million annually within the U.S., representing the subset of MS patients with gait impairment.
Competitor Landscape
Key competitors:
- Dalfampridine (generic forms) – patent expired, but limited generic availability due to ongoing patent litigation.
- Biological agents – such as ocrelizumab and natalizumab, indirectly improving mobility by altering disease progression, but not direct competitors for gait aid.
- Other symptomatic treatments – including physical therapy and mobility aids, which do not replace pharmaceutical therapy.
Market share:
- Acorda Therapeutics maintains approximately 85% market share in gait-improvement drugs for MS due to early market entry and established prescribing patterns.
- Generic competition remains limited as of Q1 2023; patent disputes continue to delay widespread generic penetration.
Market Trends and Dynamics
- The MS population is aging, with an increasing prevalence among patients aged 40-60.
- The approval of disease-modifying therapies (DMTs) has shifted focus to symptomatic treatments, maintaining demand for medications like Ampyra.
- Recent market entry of biosimilars is minimal due to complex formulations and patent protections.
- Healthcare providers increasingly prioritize quality of life, fostering sustained demand.

Price Drivers
- Patent protections delay generic entry, supporting higher prices.
- Manufacturing costs for extended-release formulations are high, influencing wholesale price.
- Reimbursement policies affect out-of-pocket payments; coverage is generally comprehensive under Medicare and private insurers.
Historical Pricing Trends
- Since FDA approval, the per-unit price has seen minimal fluctuation; the 2023 monthly cost remains consistent with 2018 levels after a slight increase driven by inflation and manufacturing costs.
- Price increases of 2-3% annually have been observed over the past five years, aligned with healthcare inflation trends.
Price Projection Outlook (2023-2028)
Assumptions:
- Patent protections continue until at least 2025, limiting generic competition.
- Healthcare policies do not aggressively alter drug reimbursement structures.
- MS prevalence maintains a steady growth rate of 2% annually in the U.S.

Impact of Patent Expiry and Generic Entry
- Patent expiry expected around mid-2025.
- Generic versions, if approved promptly, could reduce prices by 30-50%.
- Delays in generic approval could sustain higher prices up to 2027.
Regulatory and Policy Environment
- The FDA has extended exclusivity for Dalfampridine patents through 2025.
- CMS and private payers have high coverage, limiting affordability concerns for insured patients.
- Legislative trends toward reducing drug prices could influence pricing strategies post-patent expiry.
Strategic Recommendations
- Monitor patent litigation closely; early generic approval could lead to significant pricing pressure.
- Consider differentiated marketing strategies emphasizing efficacy and safety profiles.
- Prepare for potential price declines post-2025 by planning manufacturing and supply chain adjustments.
Key Takeaways
- The U.S. MS gait impairment drug market is stable, with Ampyra dominating its segment.
- Pricing has remained steady due to patent protections, with potential declines following patent expiry in 2025.
- Generics could reduce prices by up to 50%, impacting margins.
- The overall market outlook remains positive but increasingly competitive as biosimilars and generics emerge.
- Policy and legal factors will significantly influence price trajectories in the coming years.
FAQs
Q1: How soon could generic versions of Ampyra become available?
A: If patent litigation concludes favorably for generic manufacturers, approval could occur as early as late 2024 or 2025.
Q2: What factors could accelerate or delay price declines?
A: Patent disputes, regulatory approval timelines, and policies on drug pricing influence generic availability and pricing.
Q3: How does Ampyra compare to other MS symptomatic treatments?
A: It improves gait speed specifically for walking impairment, unlike disease-modifying therapies that target disease progression.
Q4: What are the key risks to the current pricing outlook?
A: Regulatory changes, patent litigation delays, or new competing therapies could influence prices.
Q5: What is the primary driver of Ampyra’s current market share?
A: Early FDA approval, established prescribing habits, and high efficacy for gait impairment.
