What is NDC 73473-0303?
NDC 73473-0303 is a drug identified as Tavalisse (fostamatinib disodium hexahydrate). It is an oral spleen tyrosine kinase (Syk) inhibitor approved by the FDA for the treatment of chronic immune thrombocytopenia (ITP) in adults. The drug was marketed by Rigel Pharmaceuticals and gained FDA approval in April 2018.
Market Size and Demand Drivers
Current Market Landscape
The global ITP treatment market involves multiple options: corticosteroids, splenectomy, immunoglobulins, thrombopoietin receptor agonists, and other targeted therapies. Tavalisse carved out a niche for patients refractory to first-line treatments.
Estimated Patient Population
- U.S. adult ITP patients: Approximately 60,000 to 70,000.
- Eligible for Tavalisse (second-line or later): Estimated between 20,000 and 30,000.
Market Share and Adoption
- Initial penetration (2020-2022): Limited, due to competition from established therapies.
- Projected growth (2023-2028): Increasing approval for broader indications and better physician familiarity could boost sales. Growth rates depend heavily on clinical positioning and payer coverage.

- Current U.S. wholesale prices approximate $7,200 - $7,500, with limited immediate downward pressure.
- The market’s potential hinges on expanding indications, physician adoption, and payer acceptance.
- Patent protection until 2030 shields pricing power; biosimilar entry is unlikely before then.
- Forecasts project sales to reach $400-500 million by 2025, depending on market penetration and pricing strategies.
FAQs
Q1: How does Tavalisse compare price-wise to other ITP treatments?
A1: It is priced higher than older therapies like corticosteroids but competitive with thrombopoietin receptor agonists, which cost around $8,000-10,000 per month.
Q2: What factors could lead to price reductions for Tavalisse?
A2: Entry of generic competitors post-2030, reimbursement pressures, or significant clinical trial failures could diminish pricing power.
Q3: Are there opportunities for premium pricing?
A3: Yes, if clinical data support expanded indications or superior efficacy, especially in refractory patient populations.
Q4: How does market competition influence future revenue?
A4: A more crowded therapeutic landscape may limit growth and exert downward pressure on prices unless differentiation occurs.
Q5: What regional markets hold the most growth potential?
A5: The U.S. remains the largest market, with Europe following. Emerging markets may provide expansion opportunities if approval is obtained and pricing is adapted.
