Summary
Ruxolitinib phosphate (brand names: Jakafi, Jakavi) is a Janus kinase (JAK) inhibitor primarily approved for myelofibrosis, polycythemia vera, and graft-versus-host disease. Its therapeutic scope has expanded through ongoing clinical trials investigating efficacy in anemia, rheumatoid arthritis, and COVID-19-associated cytokine storms. Globally, the drug’s market has demonstrated robust growth driven by its expanding indications, strategic approvals, and emerging pipeline candidates. Projections indicate compounded annual growth rates (CAGRs) exceeding 8% through 2030, with North America dominating market share. Continuous clinical advancements, regulatory approvals, and trial initiations will influence this trajectory.
