Last updated: August 12, 2025
Introduction
The National Drug Code (NDC) 46122-0593 corresponds to Erenumab, marketed under the brand name Aimovig, a monoclonal antibody developed by Novartis for the prevention of migraine. Since its FDA approval in 2018, Erenumab has emerged as a pivotal treatment in the prophylactic migraine segment, especially for patients refractory to traditional therapies. This analysis evaluates the current market landscape, competitive positioning, pricing trends, and future projections to assist stakeholders in strategic decision-making.
Product Overview and Therapeutic Profile
Erenumab is a calcitonin gene-related peptide (CGRP) receptor monoclonal antibody, influencing migraine pathophysiology. Its once-monthly subcutaneous administration offers a significant advantage over oral options and traditional preventive therapies, leading to increased adoption.
The drug primarily targets adult patients with episodic or chronic migraines, representing a significant, growing market segment. The expanding understanding of migraine pathophysiology and the approval of targeted CGRP inhibitors have revolutionized preventive migraine care.
Current Market Landscape
Market Size and Demand Drivers
The global migraine treatment market, estimated at USD 5.6 billion in 2022, is projected to grow at a compound annual growth rate (CAGR) of approximately 12% over the next five years. Erenumab commands a substantial share within the CGRP class, which accounts for roughly 35% of the overall migraine market.
Key drivers include:
- Increasing prevalence of migraine (estimated at 15% globally) [1].
- Rising awareness and diagnosis rates.
- Preference for targeted biological therapies over traditional prophylactic drugs.
- Reimbursement expansion in key geographies.
- Approval of multiple CGRP inhibitors, creating a competitive landscape but also expanding total market potential.
Competitive Dynamics
Erenumab's primary competitors include:
- Fremanezumab (Teva, Lilly)
- Galcanezumab (Eli Lilly)
- Eptinezumab (Alder BioPharma/Biogen)
While these drugs differ in administration schedules and marketing strategies, the overall class exhibits strong growth driven by clinician preference for effective, well-tolerated therapies.
Market Penetration and Adoption Trends
In 2022, an estimated 12% of eligible migraine patients in the U.S. received CGRP monoclonal antibody therapy, highlighting significant room for growth (current penetration cited by IQVIA data). The slow but steady increase correlates with insurance coverage expansion and familiarization among neurologists.
Price Analysis and Trends
Historical Pricing Data
- List Price: Erenumab’s average wholesale price (AWP) has been approximately USD 6,900 per year (USD 575 per month) since FDA approval.
- Net Pricing: Reimbursement negotiations and discounts bring the effective price closer to USD 5,900– USD 6,200 annually based on payer contracts and rebates [2].
Pricing Strategy and Reimbursement Environment
Novartis originally set Erenumab at a premium over existing preventive treatments. Insurance coverage is critical for access; in the U.S., CMS and commercial payers have increasingly covered CGRP therapies, although tiered co-payments vary.
Rebate agreements, prior authorization, and formulary placements influence net prices and sales volumes. The trend toward value-based contracts and outcomes-based reimbursements could further impact net pricing dynamics.
Pricing Trends and Inflation
Over recent years, a relatively stable pricing environment has persisted, with slight adjustments reflecting inflation, negotiated rebates, and competitive pressures. The entry of biosimilars or near-biologics could pressure prices downward in future years, though as of 2023, no direct biosimilar competition exists.
Future Price Projections
Market Growth Implications
Forecasts project the global migraine biologics market reaching USD 14 billion by 2027, with CGRP inhibitors likely accounting for over 60% of that (assuming continued adoption and expanded indications) [3].
Pricing Trajectory
Given increasing competition among CGRP inhibitors, price convergence is anticipated. Anticipated trends include:
- Slight reductions in list prices (~5–10%) over the next three years.
- Greater emphasis on outcome-based reimbursement, potentially leading to variable effective prices.
- Payer pressure leading to discounts, especially outside the U.S.

Key Takeaways
- Market Momentum: The CGRP migraine segment is poised for robust growth, driven by increased awareness, expanding indications, and superior efficacy.
- Pricing Stability with Downward Pressure: While current prices remain high (~USD 6,000 annually), market saturation and heightened competition could lead to gradual price reductions.
- Reimbursement as a Critical Factor: Coverage policies and formulary placements significantly influence net prices and access.
- Near-Term Opportunities: Expansion into new geographic markets and broader patient populations can sustain revenue growth despite pricing pressures.
- Long-Term Outlook: Price erosion is likely, emphasizing the need for health economics and outcome research to support value-based reimbursement models.
FAQs
1. What factors influence the pricing of Erenumab (NDC 46122-0593)?
Pricing is influenced by manufacturing costs, market competition, payer negotiations, hospital and pharmacy rebates, regulatory factors, and value assessments demonstrating clinical benefits.
2. How does Erenumab compare economically with other migraine preventive therapies?
Biologic CGRP inhibitors like Erenumab generally have higher upfront costs than traditional oral preventives. However, improved efficacy and tolerability can reduce overall healthcare costs through fewer migraine days and emergency visits.
3. What is the outlook for prices of Erenumab in the next five years?
Prices are expected to remain relatively stable with slight declines (~5–10%), driven by increased competition, market saturation, and shifts toward value-based reimbursement models.
4. How does market competition impact Erenumab's pricing strategy?
Competition from other CGRP inhibitors fosters price competition, encouraging manufacturers to optimize pricing strategies, negotiate better rebates, and demonstrate cost-effectiveness to payers.
5. Are biosimilar or generic options anticipated for Erenumab?
As a biologic, Erenumab is protected by patent exclusivity, with biosimilar development unlikely before 2030, contingent on patent expirations and regulatory pathways.
