Opposition Proceedings Against Akebia
In September 2018, Dr. Reddy’s Laboratories Limited filed an opposition to our issued Indian Patent No. 287720 covering the composition of matter of vadadustat in the Indian Patent Office. In response to a preliminary opinion, we requested to amend the claims, and the amended claims were published on May 9, 2025. On December 19, 2025, we attended an oral hearing conducted on the basis of the amended claims.
On November 6, 2024, Sandoz AG, or Sandoz , filed an opposition against our issued European Patent No. 3007695 covering vadadustat once daily dosing regimen in the European Patent Office, or the EPO . On March 18, 2025, we timely submitted a Patent Proprietor’s Reply to the Notice of Opposition. Oral proceedings were scheduled for February 24-25, 2026. However, on December 8, 2025, Sandoz withdrew the opposition and the EPO issued a Brief Communication on December 11, 2025, stating that Sandoz is no longer a party to the proceedings. On January 13, 2026, the EPO issued a Brief Communication stating that the oral proceedings are cancelled and the procedure will be continued in writing. On January 15, 2026, the EPO issued a decision to discontinue the opposition proceedings.
