The acquisition of Schering was the largest take-over in Bayer’s history. Under the name Bayer Schering Pharma AG, Germany* , the joint pharmaceutical company is now aiming to become one of the largest players on the world market. Schering brings with it an extensive range of products in the fields of gynecology and andrology, diagnostic imaging, oncology and specialized therapeutics which ideally complement Bayer’s existing portfolio.
"Our goal is to make the future Bayer Schering Pharma AG, Germany* a strong company that ranks among the top ten pharmaceutical specialists in the world." This is how Werner Wenning, Chairman of Bayer's Board of Management, envisages the future of the new company which aims to set new standards in research and development. Like Bayer, Schering has much to offer in this area and will thus strengthen the activities of Bayer HealthCare's Pharmaceuticals Division.

Schering stands for innovation based on tradition: Schering has been actively engaged in research and development at the cutting edge of science ever since the "Green Pharmacy" was founded by Ernst Schering 155 years ago, and today is still tackling the challenges posed by medicine. Schering has been the world leader for years now with numerous products.

Schering – the world market leader in hormonal contraceptives for women

The best example of this is the birth-control pill, which many women regard as synonymous with Schering. After all, it was the Berlin-based company which introduced the first oral contraceptive to the European market in 1961. A milestone on the path to self-determined family planning which cemented the company's reputation as a hormone specialist.

State of the art: Biology lab technician Claudia Heyer works with a high-field MR system to investigate the properties of a contrast medium used in magnetic resonance imaging.

Today Schering is the world market leader in hormonal contraceptives for women - in terms of both units sold and revenue. In addition to various birth-control pills, the extensive product portfolio also includes implants, injections and intrauterine devices, used and trusted by over seven million women around the world.

Professor Ursula-Friederike Habenicht, head of Gynecology and Andrology Research, and her team are already working on the contraceptives of tomorrow. Thanks to molecular biology, it is possible to understand how the processes in the human body work right down to the molecular level. "This opens the door to entirely new possibilities, such as the targeted suppression of sperm maturation in the epididymis. New developments are also happening in female contraception, and we are looking for other safe alternatives for women," says Habenicht.

In addition to their contraceptive effect, hormones have other characteristics that can be useful in therapy. For instance, they can relieve menopausal symptoms as well as preventing osteoporosis and especially hot flushes. An active ingredient to combat endometriosis (growth of endometrial cells outside of the uterus) is currently undergoing clinical testing.

Andrology research has given rise to products which counteract testosterone deficiency. But the development of hormone preparations is just one facet of the research conducted at Schering.

Further business units with innovative products and substances

Another focal point is Diagnostic Imaging. This too is a traditional sphere of operation at Schering, which introduced the "prototype" of the iodine-based X-ray contrast media to the market in 1931. It remained the standard for X-rays of the kidneys, bladder and blood vessels for decades.

Innovative tests: In high-throughput screening (HTS) special systems are used to test a large number of substances for potential efficacy in new therapeutic approaches. The photo shows Huyen Dan Tran, Alexander Dimerski and Jutta Treske (from left) loading microtiter plates into a high-throughput multipurpose measuring system.

In addition to classic X-rays, doctors can now turn to high-resolution diagnostic methods such as computer tomography (CT), magnetic resonance imaging (MRI), ultrasound and nuclear diagnostic methods, for which Schering supplies the appropriate contrast media. "Schering is the world market leader and regarded as a trendsetter in particular for MRI contrast media. Magnevist®, the world's first MRI contrast medium, has already been used over 70 million times," says Professor Matthias Bräutigam, head of Diagnostic Imaging Research. The organ-specific products Primovist® and Gadovist® help in early identification of tumors and other liver damage. Schering once again played a pioneering role with Vasovist®, this time in the field of vascular imaging (MRI angiography). This preparation reveals constricted areas and blockages in even the tiniest of blood vessels. MRI with Vasovist® could soon replace the high-risk heart catheter exam. A fluorescent dye for optical mammography is also in development.

The third business area is Oncology, where Schering has made innovative treatment concepts a priority and assumed a leading role in the treatment of leukemia and lymphoma. A chemotherapy agent and a humanized monoclonal antibody are significantly prolonging survival and improving the quality of life of patients with chronic lymphatic leukemia (CLL).

The first approved radio-immunotherapy agent is helping patients whose non-Hodgkin lymphoma (NHL) does not respond to standard therapy. NHL is the fifth most common form of cancer in Germany. The antibody attaches specifically to the cancer cells and destroys them with yttrium-90, the radioactive substance linked to it.

Schering researchers have also been studying solid, localized tumors. Dr. Klaus Bosslet, head of Oncology Research, says: "We are currently testing a synthetic epothilone for treatment of prostate, ovarian and breast cancer as well as an active substance which inhibits the formation of new blood vessels (angiogenesis) supplying the tumor, thus making metastasis more difficult."

Schering is also active in Specialized Therapeutics, a division with a relatively small number of products, yet very important ones. A drug that is now approved for all episodic forms of multiple sclerosis (MS) has been Schering's top-selling product for many years. MS, a progressive, chronic inflammatory disease of the central nervous system, is not yet curable. Long-term therapy with the drug reduces the frequency of MS episodes by about 30 percent, i.e. on average, one in three episodes is suppressed.

A new kind of cell therapy for treatment of patients with Parkinson's disease is an example of high-tech at its best. Elke Reisig, the Core Clinician working on the development of this treatment, says: "Initial studies show that human retinal cells from donor material attached to tiny microcarriers continuously produce the missing neurotransmitter dopamine in the brains of these patients and lastingly improve disease symptoms." Such findings bring with them a ray of hope for patients, doctors and naturally for the new company Bayer Schering Pharma AG, Germany*.
