These announcements follow earlier reports on 22 June 2026 concerning the IgA nephropathy drug application and existing drug approvals, indicating consistent progress in the company's research and development activities. These pharmaceutical developments aim to contribute to patients in disease areas where Chugai focuses its efforts.
