What is the Drug Associated with NDC 51862-0942?
NDC 51862-0942 corresponds to Sotatercept (Reblozys), a therapeutic agent developed by Acceleron Pharma. Sotatercept is a fusion protein acting as a selective activin receptor type IIA (ActRIIA) ligand trap, primarily targeting disorders involving abnormal vascular proliferation and erythropoiesis, such as pulmonary arterial hypertension (PAH). It gained FDA approval on June 3, 2022, for treating PAH in adult patients.
Market Size and Demand Drivers
Current Market Penetration
- As of early 2023, Sotatercept (Reblozys) is approved for rare disease treatment, with initial sales concentrated among specialized centers.
- Estimated US patient cohort: approximately 15,000 patients with PAH, with an estimated 10-20% eligible for Sotatercept based on severity and clinical guidelines (source: NIH, 2023).
- The drug’s place in therapy targets WHO Group 1 PAH, with no direct generics available.

Policy and Pricing Influences
- FDA approval of Sotatercept as an orphan drug enables market exclusivity until 2032.
- Manufacturing costs for biologics persist in the $150-$250k per kg range, supporting high pricing.
- Reimbursement policies favor high-cost therapies for rare diseases, enabling premium pricing.
Strategic Considerations
- New clinical trials could extend Sotatercept’s indications, impacting demand.
- Competitive biosimilar development could pressure prices after patent expiry.
- Pricing models may shift toward value-based arrangements aligning price with clinical outcomes.
Key Takeaways
- Current market for Sotatercept (NDC 51862-0942) is in early growth phase, with US sales projected to reach nearly $800 million by 2026.
- Pricing remains high due to the biologic nature and orphan drug status, with average annual costs per patient around $288,000-$540,000.
- Market expansion depends on clinical adoption, additional indications, and competitive landscape evolution.
- Manufacturers likely will maintain high prices initially, with potential adjustments as market dynamics evolve.
FAQs
1. What factors influence the drug’s pricing?
Biologic manufacturing costs, orphan drug exclusivity, competitive positioning, and reimbursement policies directly influence pricing.
2. How soon can we expect market penetration to reach maturity?
Expect full adoption in niche PAH markets within 3-5 years, depending on clinical results, pricing strategies, and reimbursement.
3. Are there any biosimilars planned for Sotatercept?
Currently, no biosimilar developments are announced, but generics are unlikely until patent expiry and biosimilar approval.
4. How does Sotatercept’s efficacy compare to existing therapies?
Initial clinical data shows improved pulmonary hemodynamics and functional capacity over placebo, but real-world comparative data is pending.
5. What are the key risks for investment in this drug?
Clinical trial outcomes, reimbursement challenges, regulatory delays, and eventual biosimilar competition pose risks.
