Baxter Announces FDA Approval of Expanded Indication for TISSEEL

DEERFIELD, Ill., Jan 30, 2012 (BUSINESS WIRE) -- Baxter International Inc. announced today that the U.S. Food and Drug Administration (FDA) has approved TISSEEL [Fibrin Sealant] to include general hemostasis in surgery when control of bleeding by standard surgical techniques is ineffective or impractical. TISSEEL is effective in heparinized patients. TISSEEL mimics the final stages of the body's own blood clotting cascade, creating a clot that adheres to the wound surface and helps achieve hemostasis.

"The expanded indication for TISSEEL offers more surgeons an effective tool for controlling bleeding across a wider variety of surgical procedures," said Sibu Saha, M.D., Professor of Surgery, University of Kentucky. "This includes patients who have been treated with heparin who may have unique treatment challenges, which was the case for some of the patients involved in Baxter's clinical trials."
A Phase III clinical study assessed the safety and efficacy of TISSEEL in peripheral vascular surgery compared with manual compression, a standard of care, in 140 evaluable patients (70 patients per treatment arm). In the study, TISSEEL was shown to be statistically significantly better than manual compression in achieving hemostasis. These study results complement a clinical data package showing the safety and effectiveness of the use of TISSEEL as an adjunct to hemostasis.
"TISSEEL and its multiple application devices make it well-suited for a variety of surgical situations, such as open and laparoscopic procedures, reinforcing Baxter's commitment to supporting solutions to the surgical community," said Prof. Hartmut J. Ehrlich, M.D., vice president of global research and development in Baxter's BioScience busines

Important Risk Information

For Topical Use Only. Do not inject TISSEEL directly into the circulatory system or into highly vascularized tissue. Intravascular application of TISSEEL can lead to intravascular coagulation, may result in life-threatening thromboembolic events and may increase the likelihood of acute hypersensitivity reactions in susceptible patients. Exercise caution to minimize the risk of intravascular application when using TISSEEL in surgery.

Do not use TISSEEL in individuals with a known hypersensitivity to aprotinin.

Do not use TISSEEL for the treatment of severe or brisk arterial or venous bleeding. In these situations, TISSEEL will be washed away in the flow of blood before hemostasis can be attained.

Hypersensitivity or allergic/anaphylactoid reactions may occur with the use of TISSEEL. Such reactions may especially be seen if TISSEEL is applied repeatedly over time or in the same setting, or if systemic aprotinin has been administered previously.

Aprotonin is known to be associated with anaphylactic reactions. Even in the case of strict local application of aprotinin, there is a risk of anaphylactic reactions to aprotinin, particularly in the case of previous exposure.

Discontinue administration of TISSEEL in the event of hypersensitivity reactions. Remove remaining product from the application site.

Air or gas embolism has occurred when fibrin sealant was administered using pressurized gas. This may occur if a spray device is used at higher than recommended pressures and in close proximity to the tissue surface.

When using the EASYSPRAY device, or an equivalent spray device for open surgical procedures cleared by FDA, TISSEEL must not be sprayed in enclosed body areas and must be sprayed onto only visible application sites.

TISSEEL is denatured when exposing to solutions containing alcohol, iodine or heavy metals. If any of these substances have been used to clean the wound area, the area must be thoroughly rinsed before the application of TISSEEL.

Apply TISSEEL as a thin layer by dripping or spraying using cannula or spray set. Excess clot thickness may negatively interfere with wound healing.

The safety and effectiveness of TISSEEL used alone or in combination with biocompatible carriers in neurosurgical procedures or other surgeries involving confined spaces have not been evaluated; its use in this setting is not FDA approved.

TISSEEL is made from human plasma. It may carry a risk of transmitting infectious agents, e.g., viruses, and theoretically, the Creutzfeldt-Jakob disease (CJD) agent.
