Transkaryotic Therapies, Inc. (TKT) (TKTX) Announces Manufacturing Agreement For Dynepo


10/19/2005 5:11:25 PM

CAMBRIDGE, Mass., Aug. 3 /PRNewswire/ -- Transkaryotic Therapies, Inc. announced today it has entered into a manufacturing agreement whereby Lonza Biologics plc will manufacture Dynepo(TM), TKT's Gene- Activated(R) erythropoietin product, at Lonza's cGMP production facility in Slough, England. Financial terms were not disclosed.

"We are delighted to continue to expand our presence in the United Kingdom and to take a critical step toward making Dynepo commercially available throughout Europe," said David D. Pendergast, Ph.D. Executive Vice President and Chief Operating Officer of TKT. "Lonza, one of the world's largest and best contract manufacturing organizations, is an ideal choice because they have a proven track record in successfully manufacturing proteins at commercial scale. Dynepo is a priority program for us and, with the signing of this contract, we expect to complete the necessary manufacturing and regulatory requirements to support a commercial launch in the European Union in late 2005 or early 2006."

"We are extremely pleased TKT chose to work with us to manufacture Dynepo drug substance at our state-of-the-art facility in Slough," said Gerhard F. Klement, Head of Lonza's Biopharmaceuticals Business Sector. "Our extensive experience in the manufacture of protein therapeutics will allow us to produce a high-quality commercial product and we look forward to meeting the needs of TKT as they work to bring Dynepo to European patients."

TKT intends to market Dynepo in a manner consistent with applicable court orders in the U.S. and European patent litigation with Amgen Inc.

TKT also announced today that it has retained an advisor on U.S. antitrust law and European Union competition law, Dean Ronald Cass, to provide strategic counsel to TKT regarding potential activities by existing erythropoietin suppliers to block Dynepo's entry into the European market. Dean Cass is a former Vice Chairman of the International Trade Commission and the former Dean of Boston University School of Law. He is also a visiting professor of comparative law at the University of Lyon in France and a senior fellow at the International Centre for Economic Research in Torino, Italy.

Erythropoietin is a hormone that stimulates the production of red blood cells and is used primarily as a treatment for anemia associated with renal disease or cancer chemotherapy. By stimulating red blood cell production, erythropoietin is beneficial in the management and improvement of anemia. Other companies currently marketing erythropoietin products include Amgen Inc., Johnson & Johnson, F Hoffman-La Roche Ltd. (Boehringer Mannheim GmbH), Sankyo Company Ltd., Chugai Pharmaceutical Co., Ltd., and the pharmaceutical division of Kirin Brewery Co., Ltd.

Dynepo is a fully human erythropoietin product developed using TKT's patented gene activation technology and is approved for commercial use in the European Union for the treatment of anemia associated with kidney disease. As described in the European Public Assessment Report, or EPAR, treatment with Dynepo was comparable to epoetin alfa and was effective in raising hemoglobin and hematocrit levels in patients. In addition, there have been no reported cases of pure red cell aplasia, a condition in which the bone marrow fails to produce vital red blood cells, in patients treated with Dynepo. A copy of the EPAR is available online at http://www.tktx.com/ under the Product category.
