* Algeta to host international conference call scheduled fortomorrow at 08:00 CET, 02:00 Eastern time - details below

Oslo, Norway, 15 May 2013 - Algeta ASA (OSE: ALGETA) announces that Bayerhasreceived US Food and Drug Administration (FDA) approval for Xofigo(®)(radium Ra223 dichloride) injection for the treatment of patients with castration-resistant prostate cancer (CRPC), symptomatic bone metastases and no knownvisceral metastatic disease. Xofigo is the first alpha particle-emittingradioactive therapeutic agent approved by the FDA. It has demonstratedimprovement in overall survival (OS) and delay in time to first symptomaticskeletal event (SSE) compared to placebo in the pivotal phase III ALSYMPCAtrial[1].

The commercial production of Xofigo is underway, and first doses areexpected tobe ready for patient treatment within a few weeks. Bayer has worldwideexclusivemarketing rights for Xofigo. Algeta US, LLC and Bayer Healthcare will co-promotethe product in the US.

Andrew Kay, Algeta's President & CEO, said: "We are delighted that theFDA hastaken the decision to approve Xofigo so quickly. We are extremely pleasedto beable to make Xofigo available to US patients with castration-resistantprostatecancer, symptomatic bone metastases and no known visceral metastaticdisease. Wewill now finalize our launch preparations in the US, with theintention oflaunching Xofigo, with Bayer, as soon as possible. This approval is amajormilestone for Algeta and puts us firmly on the path to deliver on ourvision tobe a world-class oncology company bringing medicines to cancer patientsthroughour leadership in alpha particle-emitting pharmaceuticals."

"Most men with castration-resistant prostate cancer develop bonemetastases,which can decrease overall survival," said Oliver Sartor, MD, NorthAmericanPrincipal Investigator for the pivotal trial and medical director of theTulaneCancer Center (New Orleans, LA). "Xofigo has demonstrated an anti-tumoreffecton bone metastases and will be an important addition to the treatment ofthiscancer."

Bone is the most common site in the body to be affected by metastaticcancer,and bone metastases are particularly prevalent in patients with prostatecancer[2]. Approximately 90% of patients with metastatic prostate cancershowevidence of bone metastases[3](,)[4](,)[5](,)[6] Bone metastases can leadto anincrease in frequency of skeletal events[7] and are shown to be the maincauseof morbidity and death in patients with CRPC[8].

Jan Manarite, senior educational facilitator for the Prostate CancerResearchInstitute also added, "It is encouraging to have a new treatment for menwithcastration-resistant prostate cancer, who are dealing with bonemetastases.Xofigo provides another new option to treat this cancer using adifferentapproach."

Efficacy and Safety Data Supporting Xofigo(®) (radium Ra 223dichloride)Approval

The approval of Xofigo is based on data from the pivotal phase IIIALSYMPCA(ALpharadin in SYMptomatic Prostate CAncer) trial. At the interimanalysis,Xofigo significantly improved OS [HR=0.695 (95% CI 0.552-0.875),p=0.00185];median OS was 14.0 months with Xofigo plus best standard of care vs. 11.2monthswith placebo plus best standard of care(1). Additionally, at theinterimanalysis there was a delay in the time to first symptomatic skeletal event(SSE)for patients treated with Xofigo vs. placebo(1).

An updated analysis, conducted after the study was unblinded, showedimprovementin overall survival with a median OS of 14.9 months vs. 11.3 months;HR=0.695(95% CI 0.581-0.832)(1).

The most common adverse reactions (greater than or equal to 10%) inpatientsreceiving Xofigo in the ALSYMPCA trial were nausea, diarrhea,vomiting andperipheral edema. The most common hematologic laboratory abnormalities(greaterthan or equal to 10%) were anemia, lymphocytopenia, leukopenia,thrombocytopeniaand neutropenia(1).

About Xofigo(®) (radium Ra 223 dichloride)

Xofigo is indicated for the treatment of patients with castration-resistantprostate cancer, symptomatic bone metastases and no known visceralmetastaticdisease.

Xofigo is an alpha particle-emitting radioactive therapeutic agent with ananti-tumor effect on bone metastases. The active ingredient in Xofigo is thealphaparticle-emitting isotope radium-223, which mimics calcium and formscomplexeswith the bone mineral hydroxyapatite at areas of increased bone turnover,suchas bone metastases. The high linear energy transfer of Xofigo may causedouble-strand DNA breaks in adjacent cells, resulting in an anti-tumor effect onbonemetastases. The alpha particle range from radium-223 dichloride is lessthan100 micrometers which may limit the damage to the surrounding normaltissue(1).

In September 2009, Algeta signed an agreement with Bayer for thedevelopment andcommercialization of Xofigo. Under the terms of the agreement, Bayerwilldevelop, apply for health authority approvals worldwide and commercializeXofigoglobally. Algeta US, LLC will co-promote Xofigo with Bayer in the US.

Important Safety Information for Xofigo (radium Ra 223 dichloride)

Xofigo is contraindicated in women who are or may become pregnant.Xofigo cancause fetal harm when administered to a pregnant woman.

In the randomized trial, 2% of patients in the Xofigo arm experiencedbonemarrow failure or ongoing pancytopenia, compared to no patients treatedwithplacebo. There were two deaths due to bone marrow failure. For 7 of 13patientstreated with Xofigo bone marrow failure was ongoing at the time of death.Amongthe 13 patients who experienced bone marrow failure, 54% requiredbloodtransfusions. Four percent (4%) of patients in the Xofigo arm and 2%in theplacebo arm permanently discontinued therapy due to bone marrowsuppression. Inthe randomized trial, deaths related to vascular hemorrhage in associationwithmyelosuppression were observed in 1% of Xofigo-treated patientscompared to0.3% of patients treated with placebo. The incidence of infection-relateddeaths(2%), serious infections (10%), and febrile neutropenia (less than1%) wassimilar for patients treated with Xofigo and placebo. Myelosuppression -notablythrombocytopenia, neutropenia, pancytopenia, and leukopenia - has beenreportedin patients treated with Xofigo.

Monitor patients with evidence of compromised bone marrow reserveclosely andprovide supportive care measures when clinically indicated. DiscontinueXofigoin patients who experience life-threatening complications despitesupportivecare for bone marrow failure.

Monitor blood counts at baseline and prior to every dose of Xofigo.Prior tofirst administering Xofigo, the absolute neutrophil count (ANC)should begreater than to equal to 1.5 × 10(9)/L, the platelet count greaterthan or equalto 100 × 10(9)/L, and hemoglobin greater than or equal to 10g/dL. Prior tosubsequent administrations, the ANC should be greater than or equalto 1 ×10(9)/L and the platelet count greater than or equal to 50 ×10(9)/L.Discontinue Xofigo if hematologic values do not recover within 6 to 8weeksafter the last administration despite receiving supportive care.

Safety and efficacy of concomitant chemotherapy with Xofigo have notbeenestablished. Outside of a clinical trial, concomitant use of Xofigo inpatientson chemotherapy is not recommended due to the potential foradditivemyelosuppression. If chemotherapy, other systemic radioisotopes, orhemibodyexternal radiotherapy are administered during the treatment period,Xofigoshould be discontinued.

Xofigo should be received, used, and administered only by authorizedpersons indesignated clinical settings. The administration of Xofigo is associatedwithpotential risks to other persons from radiation or contamination fromspills ofbodily fluids such as urine, feces, or vomit. Therefore, radiationprotectionprecautions must be taken in accordance with national and localregulations.

The most common adverse reactions (greater than or equal to 10%) inpatientsreceiving Xofigo were nausea, diarrhea, vomiting, and peripheral edema.Grade 3and 4 adverse events were reported in 57% of Xofigo-treated patients and63% ofplacebo-treated patients. The most common hematologic laboratoryabnormalitiesin Xofigo-treated patients (greater than or equal to 10%) wereanemia,lymphocytopenia, leukopenia, thrombocytopenia, and neutropenia.

About the ALSYMPCA Trial

The ALSYMPCA trial was a phase III, randomized, double-blind, placebo-controlledinternational study of Xofigo with best standard of care vs. placebo withbeststandard of care in symptomatic CRPC patients with bone metastases. Thetrialenrolled 921 patients in more than 100 centers in 19 countries. Thestudytreatment consisted of up to six intravenous injections of Xofigo orplaceboeach separated by an interval of four weeks.

The primary endpoint of the study was overall survival (OS). A keysecondaryendpoint was time to first symptomatic skeletal event (SSE), asdefined asexternal beam radiation therapy (EBRT) to relieve skeletalsymptoms, newsymptomatic pathologic bone fracture, occurrence of spinal cordcompression, ortumor-related orthopedic surgical intervention.

About CRPC and Bone Metastases

Prostate cancer is the most common cancer among men in the United States(otherthan skin cancer)[9]. Approximately 4% of prostate cancer cases areconsidereddistant, which means that the cancer has spread beyond the prostate todistantareas of the body (metastasized)[10]. If prostate cancer starts to spreadtoother areas of the body, it most commonly goes to the bones(7).About the Patient Assistance Program
