The big picture
Otsuka’s Voyxact is entering a competitive IgAN market with strong clinical credibility, positioning itself as a preferred option for high-risk patients. The rapid early adoption suggests a significant shift in treatment paradigms, but sustained growth will depend on navigating reimbursement hurdles and maintaining differentiation against established therapies like Novartis’ Fabhalta and Calliditas’ Tarpeyo. The IgAN market is evolving with both targeted oral agents and novel biologics, making Voyxact’s strategic integration into treatment sequencing critical for long-term success.
