On Nov. 5, 2007, the U.S. Food and Drug Administration announced that Bayer Pharmaceuticals Corp. agreed to an FDA-requested marketing suspension of Trasylol, a drug used to control bleeding during heart surgery. At that time, preliminary results from a Canadian study suggested an increased risk for death compared to two other drugs used to control bleeding.
Bayer HealthCare Pharmaceuticals Inc. has notified the FDA that the company will begin removing the remaining Trasylol stock from the U.S. market, most of which is in warehouses and hospital or physician’s stock. The FDA will work with Bayer to ensure a smooth and complete process.
Under a limited use agreement, access to Trasylol is limited to investigational use of the drug according to the procedures described in a special treatment protocol. The protocol allows treatment for certain patients who are at increased risk of blood loss and transfusions during coronary artery bypass graft surgery and who have no acceptable alternative therapy. Physicians using Trasylol in this situation must also verify that the benefits of the drug clearly outweigh the risks for their patients.
FDA limits access to certain drugs to patients with serious or immediately life-threatening disease or conditions who lack other therapeutic options and may benefit from such therapies. This type of access requires the submission of a protocol, which is reviewed and approved by the agency. Bayer has agreed to provide Trasylol through this mechanism for the limited use described above.
Trasylol is an antifibrinolytic drug approved to reduce blood loss during surgery and the need for blood transfusion in certain patient undergoing cardiopulmonary bypass in the course of coronary artery bypass graft surgery. Antifibrinolyitc drugs help slow the breakdown of blood clots and subsequent excessive bleeding.
Results from a randomized Canadian study that prompted last November’s marketing suspension of Trasylol are expected to be published this week. The data contained in this article suggest that Trasylol appears to increase the risk for death compared to two other antifibrinolytic drugs used in the study.
