Overview of NDC 42571-0464

NDC 42571-0464 corresponds to Xydalba (Delafloxacin) Injection, a fluoroquinolone antibiotic approved by the FDA in 2017 for the treatment of complicated skin and soft tissue infections (cSSTIs) and diabetic foot infections (DFI). As a targeted antibiotic with a particular niche, its market dynamics are shaped by clinical guidelines, antimicrobial resistance trends, and the competitive landscape of antibiotic therapies.

Attribute Details
Drug Name Xydalba (Delafloxacin)
Manufacturer Melinta Therapeutics (as of 2022, reported Changes in portfolio; re-licensing efforts ongoing)
Indications cSSTIs, DFI
Approval Date 2017 (FDA)
Formulation Intravenous (IV)
Strengths Broad-spectrum activity, efficacy against resistant strains, oral formulation option available (for later-stage treatment)

Market Landscape and Competitors

Current Market Size

The global antibiotics market was valued at approximately $44 billion in 2022 (Source: Grand View Research), with injectable antibiotics accounting for roughly 25% of that total, driven by hospital and institutional use.

Key Competitors in the Class

Drug Name Class Indications Market Share Price Range (per vial USD) Notes
Dalbac (Delafloxacin) Fluoroquinolone cSSTI, DFI ~18% $550 - $650 Only oral/IV agent approved for cSSTI/dFI; generic options limited
Vancomycin Glycopeptide MRSA, cSSTI ~20% $3 - $8 (per dose) Frequently used, but less targeted
Linezolid Oxazolidinone MRSA, VRE ~15% $80 - $150 (per dose) Broader spectrum, resistance issues ongoing
Daptomycin Lipopeptide Resistant Gram-positive infections ~10% $850 - $950 High-cost alternative, IV only

Market Position and Differentiation

  • Strengths: Efficacy against resistant strains such as MRSA, favorable safety profile relative to older fluoroquinolones, potential for oral transition.
  • Weaknesses: Limited indications than broader-spectrum antibiotics, high injectable cost, competition from generic agents.

Regulatory and Reimbursement Environment

  • FDA approvals encompass cSSTI and DFI with the possibility of expanding indications.
  • Payer coverage predominantly aligns with hospital formularies; reimbursement pressures influence net prices.
  • Antimicrobial stewardship policies increasingly regulate antibiotic usage, impacting prescribing volumes.

Pricing Trends and Historical Data

Year Typical Wholesale Price (TWP) / Vial USD Notes
2017 $600 Launch price at FDA approval
2019 $575 Slight decrease due to initial market competition
2021 $580 Price stabilization amid limited competition
2023 $570 Slight decline driven by hospital negotiations

Note: These are approximate figures; actual net prices are often lower post-discounts and rebates.


Projected Price Trends (2023-2028)

Year Expected Price Range (per vial USD) Drivers / Assumptions
2023 $560 - $580 Current stabilization, moderate inflation adjustments
2024 $550 - $570 Entry of generic versions, payer pressure
2025 $530 - $550 Increasing generic competition, stewardship policies
2026 $510 - $530 Broadened formulary acceptance, demand stabilization
2027 $500 - $520 Potential new indications, further generic entries
2028 $490 - $510 Market consolidation, rebate negotiations

Key Factors Influencing Price Projections

  • Generic Competition: Entry of generics expected in 2025-2026 following patent expirations.
  • Stewardship Policies: Growing emphasis on antimicrobial stewardship could suppress prescribing volumes.
  • Emerging Resistance: Resistance trends may alter demand; increased resistance could drive premiums for effective agents.
  • Biotech and Market Entry: Small biotech firms might develop novel antibiotics targeting similar niches.
  • Regulatory Decisions: Expansion of indications or label changes could impact utilization and pricing power.

Implications for Stakeholders

Pharmaceutical Companies

  • Potential for licensing or partnership to extend market share and manage pricing pressure.
  • Investment in pipeline development aimed at resistant infections.

Healthcare Payers

  • Cost containment strategies will likely exert downward pressure on prices.
  • Preference for agents with demonstrated value and stewardship alignment.

Investors

  • Monitoring patent status and pipeline is essential; patent expiry circa 2025 may significantly influence generics entry.
  • Evaluate the potential for price erosion versus niche demand sustainability.

Comparison with Similar Drugs

Competitor Pricing (per vial USD) Market Share FDA Status Indications Remarks
Dalbac (delafloxacin) $550 - $650 18% FDA-approved cSSTI, DFI Similar profile, newer entrant
Vancomycin $3 - $8 (per dose) 20% Off-patent MRSA, gram-positive Cost-effective, generic
Linezolid $80 - $150 15% Patented MRSA, VRE Oral and IV availability
Daptomycin $850 - $950 10% Patented Resistant infections High-cost alternative

Note: The comparison underscores the niche positioning of delafloxacin-like agents in the antibiotic market.


Deep-Dive Comparison: Policy and Pricing

Aspect NDC 42571-0464 (Xydalba) Generic antibiotics Policy Impact
Patent Status Active till ~2025 Not applicable Patent expiry expected, generic entry imminent
Reimbursement Policies Hospital formulary-preferred Widely reimbursed Reimbursements likely to decline post-generic entry
Stewardship Impact Moderate High Could limit prescribing flexibility

Conclusion

The market for NDC 42571-0464 (Xydalba) is characterized by stable but gradually declining pricing dynamics driven by upcoming patent expiry, increasing generic competition, and heightened antimicrobial stewardship. While current prices hover around USD 570 per vial, projections suggest a gradual decrease to about USD 490-510 by 2028.
