About Radium-223 Dichloride (Xofigo®)
Radium-223 dichloride (radium-223) is a therapeutic alpha particle-emitting pharmaceutical with an anti-tumor effect on bone metastases. Radium-223 mimics calcium and selectively targets bone, specifically areas of bone metastases, by forming complexes with the bone mineral hydroxyapatite. The high linear energy transfer of alpha emitters leads to a high frequency of double-strand DNA breaks in adjacent tumor cells, resulting in a potent cytotoxic effect. The alpha particle range from radium-223 is less than 100 micrometers, which minimizes damage to the surrounding normal tissue.

Radium-223 dichloride has been approved under the brand name Xofigo® in more than 40 countries worldwide, including the U.S. and the EU. In Europe, it is approved for the treatment of adults with CRPC, symptomatic bone metastases and no known visceral metastases.

About Sorafenib (Nexavar®)
Sorafenib, an oral anti-cancer therapy, is approved under the brand name Nexavar® in more than 100 countries worldwide. In Europe, Nexavar is approved for the treatment of hepatocellular carcinoma (HCC); for the treatment of patients with advanced renal cell carcinoma (RCC) who have failed prior interferon-alpha or interleukin-2 based therapy or are considered unsuitable for such therapy; and for progressive, locally advanced or metastatic, differentiated (papillary/follicular/Hürthle cell) thyroid carcinoma, refractory to radioactive iodine.

In preclinical studies, sorafenib has been shown to inhibit multiple kinases thought to be involved in both cell proliferation (growth) and angiogenesis (blood supply) - two important processes that enable cancer growth. These kinases include Raf kinase, VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-B, KIT, FLT-3 and RET.

Nexavar is co-developed by Onyx Pharmaceuticals, Inc., an Amgen subsidiary, and Bayer, except in Japan where Bayer manages all development. The companies co-promote Nexavar in the U.S. Outside of the U.S., excluding Japan, Bayer has exclusive marketing rights, and Bayer and Onyx share profits globally.

About ODM-201
ODM-201 is an investigational novel androgen receptor (AR) antagonist with unique chemistry that is designed to block the growth of prostate cancer cells. ODM-201 binds to the AR with high affinity and inhibits receptor function. In nonclinical models, ODM-201 has shown to only minimally penetrate the blood-brain barrier.

In 2014, Bayer and Orion had entered into a global agreement under which they will jointly develop ODM-201, with Bayer contributing a major share of the costs of future development. Bayer will commercialize ODM-201 globally and Orion has the option to co-promote ODM-201 in Europe. Orion will be responsible for the manufacturing of the product.
