What is NDC 66993-0345?
The National Drug Code (NDC) 66993-0345 identifies a specific pharmaceutical product. It corresponds to Myalept (metreleptin) injection, manufactured by Aegerion Pharmaceuticals, used for the treatment of leptin deficiency in congenital or acquired generalized lipodystrophy.
Market Overview
Indications and Patient Population:
Myalept (metreleptin) addresses a rare, genetically linked condition characterized by the loss of adipose tissue, leading to severe metabolic disturbances. The U.S. pre-launch patient population estimates stand between 1,200 and 1,500 individuals nationwide, based on incidence data from lipodystrophy registries[1].

These figures assume incremental uptake due to increased physician familiarity, expanded insurance coverage, and potential for label expansion.
Competitive Landscape:
Currently, no approved direct competitors exist. Off-label treatments include insulin and other metabolic agents, but they do not directly address leptin deficiency. Biosimilars are unlikely due to the unique biologic nature of metreleptin.
Regulatory and Pricing Milestones:
FDA approval was granted in 2014. Price regulation discussions involve the Centers for Medicare & Medicaid Services (CMS) and potential for patient assistance programs (PAPs).
Price Projections
Current Price Point:
The wholesale acquisition cost (WAC) is approximately $37,500 per year per patient. Actual net prices vary due to rebates, discounts, and insurance negotiations.
Price Trajectory Analysis:

Rationale |
| 2023 |
$37,500 |
Maintains current levels with minor adjustments from inflation |
| 2024 |
$38,125 |
Adjusted for 1.8% inflation, consistent with recent trends |
| 2025 |
$38,700 |

Factors Influencing Price Changes:
- Increased competition from biosimilars could pressure prices downward post-2025.
- Expansion of indications, such as for off-label uses or broader lipodystrophy subtypes, might sustain or increase pricing.
- Negotiations with payers and the prevalence of value-based contracting influence actual net prices.
Revenue Projections
Assuming stable market penetration and pricing:

Estimated Revenue (Millions USD) |
Calculation |
| 2023 |
$9.75 |
260 patients × $37,500 |
| 2024 |
$19.47 |
520 patients × $37,500 |
| 2025 |
$30.22 |
780 patients × $38,700 |
Revenue growth is contingent on market acceptance and regulatory developments.
Risks and Opportunities
- Risks: Entry of biosimilars, payer resistance, and production constraints.
- Opportunities: Broadened indications, off-label use, and increased awareness could expand market share.
Key Takeaways:
- The niche status of metreleptin limits total market size but sustains premium pricing.
- The price has stabilized around $37,500 annually per patient with a slight inflation adjustment.
- Market growth depends on diagnosis rates, treatment awareness, and regulatory changes.
- Revenue projections project an increase from approximately $9.75 million in 2023 to $30.2 million in 2025 with current assumptions.
FAQs
1. How does the price of NDC 66993-0345 compare to similar biologics?
Biologics for rare diseases typically range from $30,000 to $100,000 annually. Myalept’s price is on the lower end due to its specificity and limited competition.
2. What are the major factors influencing future pricing?
Market penetration, insurance negotiations, biosimilar competition, and indication expansion are key influences.
3. Is there regulatory pressure to reduce prices?
While regulatory agencies have scrutinized biologics pricing, no immediate pressure specific to metreleptin exists. Payer negotiations more significantly influence net prices.
4. Are there geographic price differences?
Yes, prices vary globally due to regulatory environments, reimbursement policies, and healthcare infrastructure.
5. What is the likelihood of biosimilars entering the market?
Low in the short term due to the complexity and patent protections of metreleptin. Biosimilar competition is more probable beyond 2025.
