Bayer HealthCare and Genzyme Finalize Strategic Alliance Agreement

The Bayer GroupBayer HealthCare and Genzyme Corporation have received regulatory approvals for the strategic alliance announced on March 31, 2009. With these approvals, the legal closing of the transaction was completed on May 29, 2009. Under the terms of the agreement, Bayer licenses its hematological oncology products to Genzyme and transfers its current commercial portfolio of these products to Genzyme. In many countries around the world Genzyme will begin to market and sell Campath® / MabCampath® (alemtuzumab), Fludara® (fludarabine) and Leukine® (sargramostim) as of today. Genzyme now has full responsibility for developing, marketing and selling the acquired oncology products and will record sales revenue in the United States and more than 90 other countries where they are sold. During a transition period following closing, Genzyme has contracted with Bayer to provide continuing services in certain countries to ensure no interruption in product supply to patients or support services to providers.

Under the agreement, Bayer will also return to Genzyme the worldwide distribution and development rights for alemtuzumab. The companies will also continue their co-development partnership for alemtuzumab in multiple sclerosis (MS) and should the drug be approved in this indication, Bayer and Genzyme will co-promote the drug worldwide. In addition, following FDA licensure, Genzyme will acquire from Bayer the new US Leukine manufacturing facility in Seattle, Washington. Bayer will continue to produce Fludara as a contract manufacturer for Genzyme.

"This transaction provides greater long-term profitability for two of our most important franchises - MS and Oncology - and affirms our strong commitment to better serve patients and physicians in the MS community," said Gunnar Riemann, Member of Bayer HealthCare's Executive Committee.

About Alemtuzumab / Campath
Campath® is approved in the United States as a single agent for the treatment of B-cell chronic lymphocytic leukemia (B-CLL). In the EU, MabCampath® is approved for the treatment of patients with B-CLL for whom fludarabine combination chemotherapy is not appropriate. The product was launched in its oncology indication in 2001 in the US, where it is marketed by Bayer HealthCare Pharmaceuticals Inc. as Campath, and in Europe, where it is named MabCampath. Alemtuzumab is a humanized monoclonal antibody that binds to a specific target, CD52, on cell surfaces and directs the body's immune system to destroy those cells. It is the first and only monoclonal antibody approved by the FDA for the treatment of patients with B-CLL.

About Leukine
Leukine® (sargramostim) is a growth factor that helps fight infection and disease in appropriate patients by enhancing immune cell function. Leukine was approved in the United States in 1991, and is marketed by Bayer HealthCare Pharmaceuticals. Leukine is the only growth factor approved in the US for use following induction chemotherapy in older adults with acute myelogenous leukemia (AML) to shorten the time to neutrophil recovery and reduce the incidence of severe and life-threatening infections and infections resulting in death. Leukine has also been approved in the US for use in four additional indications: myeloid reconstitution following allogeneic and autologous bone marrow transplantation (BMT), peripheral blood stem cell (PBSC) mobilization and subsequent myeloid reconstitution in patients undergoing PBSC transplantation, and bone marrow transplantation failure or engraftment delay.

About Fludara
Unlike alkylating cytotoxic chemotherapies, Fludara®, a purine nucleotide analog, inhibits the synthesis of new DNA, thus preventing leukemia cells from multiplying. The intravenous (i.v.) formulation of Fludara was first approved in 1991 and is available in 98 countries worldwide as a second-line therapy for B-CLL patients who have failed to respond to previous treatment with alkylating agents. In addition, Fludara i.v. has been approved as a first-line therapy of B-CLL in 62 countries. In 29 countries, Fludara i.v. is also approved for the second-line treatment of low grade non-Hodgkin’s Lymphoma (lg-NHL). The oral formulation has the same effect as the i.v. formulation and was approved in Europe in 2001.
