US Nuclear Regulatory Commission issues a licensing decision under 10 CFR Part 35 Subpart E for radium-223 dichloride

Not Intended for US Media Oslo, Norway, 14 January 2013 - Algeta ASA (OSE: ALGETA) announces that the US Nuclear Regulatory Commission (NRC) has issued a licensing decision on the medical use of radium-223 dichloride (radium-223). The NRC licensing decision follows the recommendation from the Advisory Committee on the Medical Use of Isotopes (ACMUI) report, dated 20 November 2012. Radium-223 is an investigational agent and is not approved by the European Medicines Agency (EMA), the US Food and Drug Administration (FDA) or other health authorities. The US NRC has ruled that sites can procure and administer radium-223 under 10 CFR Part 35, Subpart E, which includes 10 CFR § 35.300. It has also ruled that physicians authorized under 10 CFR § 35.390 or 10 CFR § 35.396 can be authorized for the medical use of radium-223. The US NRC has notified the Agreement States regarding their licensing decision on radium-223. In December 2012, Bayer submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) and a New Drug Application (NDA) to the US Food and Drug Administration (FDA) for radium-223 for the treatment of castration-resistant prostate cancer (CRPC) patients with bone metastases. Radium-223 has been granted fast track designation for this indication by FDA. ### About Radium-223 Dichloride Radium-223 dichloride (radium-223), formerly referred to as Alpharadin, is a therapeutic alpha particle-emitting pharmaceutical with targeted anti-tumor effect on bone metastases in development for CRPC patients with bone metastases.
