What is the drug associated with NDC 67777-0217?
The National Drug Code (NDC) 67777-0217 corresponds to Rylaze (li Zulirex), a recombinant enzyme used for the treatment of acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). It is indicated for patients who have developed hypersensitivity to E. coli-derived L-asparaginase.
Market Size and Growth Drivers
Current Market Landscape
- Incidence of target conditions: Approximately 6,650 cases of ALL diagnosed in the U.S. annually (SEER, 2022).
- Treatment adoption rate: Estimates indicate Rylaze is used in 35-50% of pediatric ALL patients, depending on treatment protocols.
- Market penetration: Covered by most major insurers and Medicaid, with ongoing inclusion in standard treatment guidelines.
Competitive Landscape
- Key competitors:
- Asparlas (calaspargase pegol)
- Kidrolase (E. coli asparaginase)
- Erwinase (E. coli asparaginase)
- Market share trends:
- Rylaze's innovative polyethylene glycol [PEG] formulation aims to extend dosing intervals, improving compliance.
- Increased preference for PEGylated formulations correlates with higher overall market share.
Growth Drivers
- Increased adoption for adult ALL and resistant pediatric cases.
- Expansion into hospital outpatient settings.
- Growing awareness of adverse reactions associated with bacterial-derived asparaginases.
Pricing Analysis
Current Price Points
- List Price: Estimated at $28,000 per vial (approximate, based on preliminary market reports).
- Typical Regimen: 1 vial per week for up to 4 weeks, plus additional doses during maintenance.

Price Trends and Projections
- Initial launch (2021): Priced at around $28,000 per vial.
- Expected trend:
- Slight decline expected in the next 2-3 years due to increased biosimilar competition.
- Potential for price stabilization if clinical data support broader usage.
- Possible reduction in price margins as volume increases.
Reimbursement Dynamics
- Medicare, Medicaid, and private insurers typically cover at least 80-90% of drug costs.
- Prior authorization tends to restrict access initially, but expanded coverage may lower patient costs over time.

FAQs
1. How does Rylaze compare to other asparaginase agents in terms of cost?
Rylaze is more expensive per vial (~$28,000) than bacterial-origin agents like Kidrolase (~$8,000). Its PEGylated formulation provides dosing advantages, which may justify higher costs.
2. What factors could influence the price of Rylaze over the next five years?
Market competition from biosimilars, changes in reimbursement policies, and clinical adoption rates directly impact pricing.
3. Is there potential for biosimilars of Rylaze?
Yes. Biosimilar development is underway for several PEGylated proteins; biosimilars could enter the market within 3-5 years, influencing prices.
4. How significant is Rylaze’s role in current ALL treatment protocols?
Rylaze is used primarily for patients who develop hypersensitivity to bacterial-derived enzymes and is increasingly adopted in combination regimens for resistant cases.
5. Are there emerging therapies that could disrupt Rylaze’s market share?
Novel enzyme formulations, monoclonal antibodies targeting similar pathways, and gene therapies may alter the market landscape over the coming decade.
