RAXIBACUMAB
RAXIBACUMAB is indicated for the treatment of Inhalational Anthrax.
How RAXIBACUMAB Works
Raxibacumab is a monoclonal antibody that specifically binds to the protective antigen (PA) of Bacillus anthracis. By targeting this antigen, the drug neutralizes the toxins produced by the bacteria to prevent their harmful effects. Raxibacumab does not have direct antibacterial activity and must be used in conjunction with antibacterial drugs to address the underlying infection.

How We Calculate These Metrics
Trial Activity Stage
Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.
Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.
- Growth: High proportion of early-phase trials (Phase 1/2), active development
- Expansion: Significant Phase 3 activity, approaching or pursuing approvals
- Mature: Substantial Phase 4 post-marketing studies
- Stable: Mixed phase distribution, steady development
- Declining: Low active trial ratio, reduced R&D investment
