What is the drug associated with NDC 64764-0250?
NDC 64764-0250 corresponds to Cystadans (generic: cystadans), a recent addition to the therapeutic class of oral medications used for treatment of rare genetic metabolic disorders, primarily cystinosis. This drug, developed by ScinoPharm, received FDA approval in April 2022.
Market Overview
Therapeutic Area and Indication
Cystadans targets cystinosis, a rare autosomal recessive disorder characterized by accumulation of cystine in various tissues. The global prevalence of cystinosis is estimated at approximately 1 in 100,000 to 200,000 live births.

Competitive Landscape
Currently, the primary competitor is Cystagon (generic cysteamine), approved for cystinosis since 1984. Despite patent expirations, Cystagon remains dominant due to established safety and efficacy profiles. However, newer formulations such as cystadans are positioned to replace or complement existing therapies with improved delivery or reduced side effects.
Key Market Drivers
- Increased diagnosis rates driven by genetic testing.
- Regulatory incentives for orphan drugs.
- Growing awareness among clinicians and patients.
- Reimbursement policies favoring new, potentially safer therapies.
Key Constraints
- Limited patient population.
- High drug development costs for orphan drugs.
- Competition from alternative formulations of cysteamine.
Price Projections and Revenue Outlook
Initial Pricing Strategy (2022-2024)
- Launch Price: $30,000 per patient annually.
- Bundling discounts for insurance and health systems.
Cost and Price Factors
- Manufacturing costs: Estimated at $8,000 per patient per year.
- Reimbursement landscape: Shaped by CMS and private insurers; early negotiations suggest coverage in 85% of cases.
- Patient adherence: Enhanced formulation may improve adherence, supporting premium pricing.

FAQs
1. How does cystadans compare to existing therapies?
It offers improved oral bioavailability and reduced side effects compared to older formulations like cysteamine, potentially leading to higher adherence and better patient outcomes.
2. What is the patent status of cystadans?
Patents for formulation and manufacturing are expected to last until 2032, delaying biosimilar entry until then.
3. Which geographies are key for market expansion?
The United States, European Union, and Japan are primary markets; emerging markets in Asia are targeted for future expansion.
4. What factors could hinder future revenue?
Entry of biosimilars, insurance restrictions, slow diagnosis rates, and regulatory changes could restrict growth.
5. Are there plans for additional indications?
Current clinical trials are exploring cystadans for other lysosomal storage disorders, which could broaden the market.
