Baxter acquires surgical products

Baxter International Inc., a global medical products company, said Monday that it will acquire two hemostat and sealant products from Mallinckrodt.

It will acquire Recothrom Thrombin topical, the first and only stand-alone recombinant thrombin, and Preveleak Surgical Sealant, which is used in vascular reconstruction.

"Uncontrolled intraoperative bleeding can lead to a wide variety of clinical and economic complications for patients and hospitals. As a leading provider of advanced hemostats and sealants, Deerfield-based Baxter is focused on continually identifying solutions to help meet surgeons' varying needs," said Wil Boren, president of Baxter's Advanced Surgery business. "We are excited about the addition of Recothrom to help surgeons address less severe intraoperative bleeding and Preveleak to complement Baxter's existing portfolio of sealants for cardiovascular and other surgical specialties."

Thrombin is a proven blood coagulation agent -- used on its own or in combination with other hemostats -- that has been estimated to be used in more than one million patients per year in the United States to help surgeons address intraoperative bleeding.

Recothrom is a thrombin-based product indicated as an aid to hemostasis whenever oozing blood and minor bleeding from capillaries and small venules is accessible and control of bleeding by standard surgical techniques is ineffective or impractical in adults and pediatric populations greater than or equal to one month of age. As the only topical hemostat from recombinant DNA origin approved in the United States and Canada, Recothrom can be used in pediatric and adult patients with or without antibodies to bovine-derived thrombin.

The acquisition also includes Preveleak, a surgical sealant designed to seal suture holes formed during surgical repair of the circulatory system and to reinforce sutured connections between blood vessels. Preveleak augments Baxter's portfolio of complementary hemostats, sealants and tissue products used in cardiovascular and other surgeries, offering surgeons additional clinically differentiated products to address patients' varying needs. Preveleak is approved in the United States and European Union.

Sales of the proposed acquired products totaled approximately $56 million in the twelve months preceding Sept. 29. Upon closing, the deal is expected to be modestly accretive to Baxter's 2018 adjusted earnings and increasingly accretive thereafter. Under the terms of the agreement, Baxter will acquire Recothrom and Preveleak for an upfront payment of approximately $153 million and potential contingent payments in the future.

The transaction is expected to close in the first half of 2018, subject to the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary closing conditions.

Hemostasis Solution Controls Bleeding during Surgery

A novel handheld device delivers a powder based on collagen to help surgeons achieve hemostatic bleeding control during surgical procedures.

The Biom’Up (Saint-Priest, France) HemoBlast Bellows is a sterile delivery device that is preloaded with a dry, sterile powder made of highly purified porcine collagen, glucose, chondroitin sulfate, and thrombin. The hemostatic powder is applied to the source of the bleeding by squeezing the bellows. Once applied, the powdered collagen and glucose components start the coagulation process by absorbing blood, concentrating coagulation factors and platelets, and providing a surface for autologous coagulation to begin.

In addition to collagen, the thrombin component, collected from pooled human plasma (an ancillary blood derivative) is included in the powder to boost the effect of the hemostatic agent. The thrombin facilitates the conversion of fibrinogen to fibrin, which allows the blood to clot. The chondroitin sulfate powder component provides cohesion between the hemostatic wound and the surrounding tissue. Users do not need to thaw, mix, or heat the powder, which is absorbed by the body within four weeks.


“As the first active hemostatic powder, it will support surgeons in their care for their patients with a simple, effective, and holistic solution for the management of bleeding” said Etienne Binant, CEO of Biom’up. “Biom'up has created innovative and clinically proven products that cover many different surgical specialties - orthopedics, spinal, cardiac, general, and maxillo-facial and dental.”

Studies have shown that during general surgical procedures, the HemoBlast Bellows device achieved 93% efficacy for hemostasis within six minutes, with a significantly shorter preparation time. Common adverse events included abnormal bloodwork, anemia, arrhythmia, and pain, none of which were related to the device itself. No unanticipated adverse device effects occurred.

Collagen is the main structural protein of connective tissue, making up 25-35% of the whole-body protein content. It is one of the body’s key natural resources and a component of skin tissue that can benefit all stages of the wound healing process. The importance of re-establishing a functional extracellular matrix (ECM) in chronic wounds has led to a renewed interest in collagen-based wound healing products, which can be applied either in the surgical or clinical setting, serving as a natural wound dressing with properties that artificial wound dressings do not possess.
