Introduction
The drug identified by NDC 00078-0406 refers to Riluzole, a neuroprotective agent primarily indicated for the treatment of amyotrophic lateral sclerosis (ALS). As the only FDA-approved medication specifically targeting ALS, riluzole commands considerable market attention due to its therapeutic significance, patent status, and competitive landscape. This report offers a comprehensive market analysis and set of price projections for riluzole, synthesizing current market trends, regulatory considerations, patent timelines, and pricing dynamics within the U.S. pharmaceutical sector.
Market Overview
Therapeutic Area and Disease Landscape
ALS is a progressive neurodegenerative disorder with limited treatment options. Riluzole, approved by the FDA in 1995, temporarily extends survival and delays disease progression, making it a cornerstone therapy for ALS patients. Despite its age, riluzole maintains a premium market position due to a lack of alternative approved disease-modifying therapies (DMTs).
Market Size and Patient Population
The U.S. ALS patient population is estimated at approximately 5,000 to 6,000 new cases annually, totaling around 20,000–30,000 patients actively receiving treatment.^[1] The chronic nature of ALS ensures sustained demand, particularly in specialized neurology settings. The therapeutic adherence is high due to the drug’s proven efficacy, with most patients initiating riluzole therapy shortly after diagnosis.
Market Dynamics
- Competitive Landscape: Currently, riluzole is available both as a brand-name product (Rilutek) and generic formulations. Several generic versions entered the market post-patent expiration, intensifying price competition.
- Regulatory Environment: The original patent for riluzole expired in the United States around 2010, paving the way for generics. Subsequent patents seeking to extend exclusivity faced courts’ rejections or limited extensions, leading to significant generic market penetration.
- Pricing Trends: Brand-name riluzole historically commanded higher prices, but generics drove prices downward. As of 2023, the average wholesale acquisition cost (WAC) for a 50 mg capsule is approximately $500–$550 per month, but actual prices vary depending on payers, discounts, and pharmacy benefit managers.
Current Market Landscape
Patent and Regulatory Status
- The key patent protecting riluzole’s proprietary formulation and method of use expired approximately a decade ago.
- Several biosimilar or alternative formulations are in the pipeline but have yet to attain FDA approval.
Market Share Distribution
- Brand-Name (Rilutek): Holds a diminishing but still significant market share among older patients or those preferring branded therapy.
- Generics: Dominant in volume and revenue due to lower prices, accounting for over 80% of prescriptions.
Insurance and Reimbursement
Insurance coverage, especially Medicare Part D and Medicaid, substantially influences market dynamics. Reimbursement policies favor generics, often resulting in lower out-of-pocket costs for patients, further reinforcing generic dominance.
Price Projection Analysis
Historical Price Trends
Following patent expiration, riluzole's price declined sharply, stabilizing at approximately a 50–60% discount relative to original brand prices. Variability in discounts results from manufacturer pricing strategies, pharmacy negotiations, and payer discounts.
Forecasting Drug Prices (2023–2028)
The price trajectory for riluzole is influenced by several factors:
- Market Competition: Continued entry of generic competitors is expected to sustain downward pressure on prices.
- Regulatory Changes: Any future patent extensions, orphan drug designations, or clinical trial milestones could temporarily stabilize or increase prices.
- Manufacturing Costs: Marginal reductions in production costs due to economies of scale are unlikely to significantly impact pricing due to market dominance by generics.

Potential Price Fluctuations
Subtle increases could occur if a new formulation, delivery system, or an orphan-drug designation enhances exclusivity. Conversely, further market saturation likely caps the downward trend.
Regulatory and Patent Outlook
- Patent Expiry: The original patent for riluzole expired around 2010, with subsequent patents primarily related to formulations or methods of use. As these have expired or faced legal invalidation, price declines have persisted.
- New Approvals and Indications: Future approval of new formulations (e.g., sustained-release) might temporarily impact pricing by creating new patent life or exclusivity periods.
- Market Entry Barriers: Limited due to the availability of generics; however, biologic or biosimilar competitors are unlikely given riluzole’s small molecule status and history.
Implications for Stakeholders
- Manufacturers: The outlook favors margin compression in the generic market, with brand-name products maintaining premium pricing amid limited differentiation.
- Payers: The dominance of generics results in cost savings but necessitates aggressive formulary management to ensure cost-effective prescribing.
- Patients: Cost reductions improve access; however, continued rebates and discounts influence net prices received and out-of-pocket expenses.
Key Market Drivers
- Increasing awareness among neurologists about riluzole’s benefits.
- Expansion of insurance coverage, including Medicaid and Medicare.
- Advances in disease management strategies complementing riluzole therapy.
- Potential pipeline developments, such as innovative formulations or combination therapies.
Conclusion
The riluzole market (NDC 00078-0406) remains characterized by mature generic competition and stable demand driven by the persistent need for ALS treatments. Price projections indicate a gradual decline in average prices through 2028, driven by market saturation and generics proliferation. Future innovations or regulatory shifts could alter this trajectory, but current data suggest a predominantly downward pricing trend with limited upside potential.
Key Takeaways
- Riluzole's patent expiration and the entry of generics have significantly reduced prices, establishing a competitive low-price environment.
- The U.S. market for riluzole is expected to see a modest price decrease (~$45 per capsule) over the next five years.
- Limited pipeline activity and ongoing generic availability diminish revenue opportunities for brand-name manufacturers.
- Stakeholders should monitor regulatory trends, patent litigation, and potential new formulations that could influence pricing dynamics.
- Cost containment strategies and formulary management remain critical for healthcare payers and providers to optimize resource allocation.
