  • Use of the new Mix2Vial® Reconstitution System manufactured by Medimop, and associated labeling changes.
  • Statements regarding the capacity of the Alphanate manufacturing process to reduce infectivity of an experimental agent of transmissible spongiform encephalopathy.
  • Revisions to sections of the Prescribing Information, including the deletion of the use of Alphanate for control and prevention of bleeding in patients with Acquired Hemophilia due to lack of data to support this indication.

All promotional claims must be consistent with and not contrary to approved labeling. You should not make a comparative promotional claim or claim of superiority over other products unless you have substantial evidence to support that claim.
