Market Analysis and Price Projections for NDC 51645-0870

Last updated: July 28, 2025

Introduction

The drug identified by the National Drug Code (NDC) 51645-0870 pertains to a pharmaceutical product marketed within the United States. Analyzing its market landscape involves understanding its therapeutic category, patent status, manufacturing dynamics, competitive environment, and healthcare demand. Accurate price projection requires dissecting these factors alongside external influences such as regulatory trends, healthcare policies, and economic conditions.

This report provides a comprehensive market assessment and price trajectory forecast, designed to inform stakeholders, investors, and healthcare providers.


Product Overview and Therapeutic Context

NDC 51645-0870 corresponds to Glatiramer Acetate (Brand: Copaxone), a disease-modifying therapy (DMT) predominantly indicated for relapsing forms of multiple sclerosis (MS) [1]. As one of the pioneering MS treatments, Glatiramer Acetate has maintained a steady presence in the neurological therapeutics market for over two decades.

The drug functions as an immune modulator, reducing the frequency of MS relapses. It is administered via subcutaneous injection, with formulations traditionally provided in 20 mg/mL daily doses.


Market Landscape

Therapeutic Market Dynamics

Multiple sclerosis is a chronic, often debilitating neurological disorder affecting approximately 2.8 million globally. The US accounts for an estimated 1 million MS patients [2], underpinning a stable demand for long-term DMTs like Glatiramer Acetate.

Emerging therapies, including oral agents (e.g., fingolimod, dimethyl fumarate), have introduced competitive pressure, but Glatiramer Acetate retains favor due to its established safety profile and extensive clinical data.

Key Market Participants

  • Teva Pharmaceuticals: Proprietary manufacturer of Copaxone, historically dominating the MS injectable market [3].
  • Mylan (now part of Viatris): Offers generic versions post patent expiration.
  • Sandoz, Momenta, and other biosimilar developers: Entered the biosimilar space, increasing price competition.
  • Biogen and Novartis: Competing with oral and monoclonal antibody therapies.

Patent and Regulatory Status

Teva's original patent for Copaxone expired in the US in 2015, leading to a wave of generic and biosimilar entrants. Despite patent expiry, Teva maintains exclusivity through formulations and delivery devices, but price competition has intensified [4].


Pricing Trends and Historical Data

Pre-Patent Expiry Pricing

Historically, the branded product cost approximately $60,000 - $70,000 annually per patient in the US [5]. The high price reflects the chronic nature of MS, manufacturing complexity, and the significant research investments.

Post-Patent and Generic Entry

Following patent expiration:

  • Generic versions entered markets at an average price reduction of 30-50%.
  • Biosimilars and authorized generics have driven further downward pressure.
  • Teva's Copaxone has maintained a premium price (~$70,000 annually), leveraging brand recognition and patient/provider loyalty.

Current Market Prices (2023)

  • Brand (Copaxone): Approx. $70,000 per year.
  • Generics and biosimilars: Range between $30,000 - $50,000 per year, depending on manufacturer and formulary negotiations [6].

Price Drivers and Market Influencers

Manufacturing Costs

Production of peptide-based biologics entails high costs, but advancements in biosimilar manufacturing have reduced entry barriers. Price reductions are partly driven by manufacturing efficiencies and competition.

Regulatory and Reimbursement Landscape

CMS and private insurers' formulary preferences influence drug pricing. Favorable negotiations for biosimilars have increased accessibility and lowered out-of-pocket expenses.

Patient Preference and Administration

The switch to biosimilars is often driven by cost considerations, though some clinicians maintain a preference for the branded product due to perceived efficacy and safety profiles.

External Factors

  • Economic pressures, like inflation and healthcare reforms, may impact drug prices.
  • Policy changes supporting biosimilars could accelerate price erosion for the original branded drug.

Price Projection (2023–2028)

Forecast Assumptions

  • Continued growth in MS prevalence.
  • Increased adoption of biosimilars and generics.
  • Ongoing regulatory support for biosimilar substitution.
  • No significant regulatory barriers emerging.

Projected Price Trends

Year Estimated Average Price (per patient/year) Notes
2023 $65,000 – $70,000 Stable for branded; biosimilars at a significant discount.
2024 $60,000 – $65,000 Slight decline as biosimilar market penetration deepens.
2025 $55,000 – $60,000 Continued shift toward generics, further price erosion.
2026 $50,000 – $55,000 Market consolidation; potential new biosimilars entering.
2027 $45,000 – $50,000 Increased biosimilar competition, payer-driven discounts.
2028 $40,000 – $45,000 Stabilization at lower prices, possibly with new formulations or delivery systems.

Note: These projections assume consistent market dynamics; unforeseen regulatory or technological disruptions could alter these estimates.


Market Opportunities and Risks

Opportunities

  • Biosimilar proliferation can substantially lower prices.
  • Value-based pricing models may incentivize innovative payer discounts.
  • Oral MS therapies may have an impact on injectable demand but could also create combination treatment pathways.

Risks

  • Patent disputes or delays in biosimilar approval.
  • Regulatory barriers hindering biosimilar market penetration.
  • Patient and provider resistance to switching from branded to biosimilars.
  • Market saturation and plateauing demand.

Key Takeaways

  • Market stability for Glatiramer Acetate persists, benefiting from its long-term clinical experience.
  • Price competition is intensifying, primarily through biosimilar entries, with potential for a 35-40% price reduction over the next five years.
  • Manufacturers must navigate regulatory pathways, reimbursement dynamics, and physician preferences for successful market positioning.
  • Stakeholders should monitor biosimilar approvals and formulary strategizing for optimal market access and cost management.
  • Investors should consider the declining pricing trend while evaluating the longevity and competitive positioning of brand versus biosimilar products.

Conclusion

The market for NDC 51645-0870 (Glatiramer Acetate, Copaxone) is characterized by a mature landscape transitioning toward increased biosimilar penetration. While the branded formulation retains premium pricing due to entrenched clinical trust, ongoing market forces suggest a downward pricing trajectory with substantial cost reductions becoming evident through biosimilar integration. Stakeholders aligning their strategies with these dynamics are more likely to succeed amid evolving reimbursement, regulatory, and competitive environments.
