What is the Drug Identified by NDC 45963-0538?
The National Drug Code (NDC) 45963-0538 corresponds to Xerava (eravacycline), an intravenous (IV) antibiotic approved by the FDA in August 2018 for complicated intra-abdominal infections (cIAI). It is a synthetic tetracycline derivative developed by Tetraphase Pharmaceuticals.
Market Overview
Indications and Use
Xerava is indicated for cIAI caused by susceptible bacteria, including Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae complex, and Bacteroides fragilis. It is used primarily in hospital settings and has limited outpatient use due to IV administration.
Competitive Landscape
- Main competitors: Zemdri (plazomicin), Merrem (meropenem), and other broad-spectrum antibiotics.
- Market penetration: Limited to hospital settings; low outpatient utilization.
- Existing resistance: Growing bacterial resistance to traditional tetracyclines enhances Xerava’s position but also underscores the importance of stewardship.
Market Size Estimation
- US cIAI Treatment Market (2023): Estimated at approximately $1.2 billion annually.
- Xerava’s market share: As a niche product, estimated at less than 5%.
- Projected sales (2023): ~$60 million.
Adoption Factors
- Efficacy against multidrug-resistant organisms enhances adoption.
- IV-only formulation restricts outpatient market growth.
- Limited clinical trial data compared to first-line therapies constrains uptake.
Price Analysis
List Price and Reimbursement
- Average wholesale price (AWP): Estimated at $2,700 per 100 mL vial.
- Average selling price (ASP): Historically 20-30% below AWP; approximate ASP ~$1,900 per vial.
Cost per Treatment Course
- Typical course: 5–7 days.
- Total medication cost per patient: $9,500 to $13,300, depending on duration.
- Additional costs include hospitalization, administration, and supportive care.
Reimbursement Landscape
- Reimbursement varies by insurer; Medicare and Medicaid reimburse based on DRGs.
- Rebate programs and negotiate discounts can reduce net price by approximately 10–15%.

Key Challenges
- Limited outpatient use due to IV formulation.
- Competitive landscape with newer antibiotics.
- Growing bacterial resistance complicates efficacy predictions.
- Payer restrictions influence reimbursement and net pricing.
Opportunities for Growth
- Expansion into hospital outpatient settings with infusion services.
- Development of formulations suitable for outpatient management.
- Use in multidrug-resistant infections as a first-line therapy.
Risks
- Emergence of resistance reducing efficacy.
- Regulatory or reimbursement changes affecting profitability.
- Competitive threats from novel oral antibiotics.
Conclusion
Xerava’s market remains niche within the broader antibiotic sector, primarily constrained to inpatient environments. Its pricing, anchored around the current ASP of ~$1,900 per vial, is stable but faces erosion from competitive pressures. Moderate volume growth is expected, with an expected revenue increase of approximately 3–5% annually over the next two years, assuming no major market disruptions.
Key Takeaways
- NDC 45963-0538 (Xerava) is an IV antibiotic with limited outpatient use.
- Market size estimated at $1.2 billion; Xerava’s share is less than 5%.
- Current ASP around $1,900 per vial, translating to annual revenues near $60 million.
- Future revenue growth depends on hospital adoption, resistance patterns, and competition.
- Price stability is likely, barring significant market or regulatory changes.
FAQs
-
Will Xerava’s sales increase with rising antibiotic resistance?
Increased resistance could expand its use in multidrug-resistant infections, potentially boosting sales.
-
Are there plans for oral formulations?
No current FDA-approved oral formulations; development could change utilization patterns.
-
How does Xerava’s price compare with other antibiotics for cIAI?
Its ASP is in the upper mid-range, comparable to similar IV broad-spectrum agents, which typically range from $1,500 to $2,500 per vial.
-
What are the major barriers to wider adoption?
Limited outpatient options, competition from oral antibiotics, and concerns about resistance.
-
Could new antibiotics erode Xerava’s market share?
Yes. Emerging agents targeting similar pathogens might lead to price competition and reduced market share.
