Radiological evidence of bone metastasis (with or without metastasis at other sites) to include plain radiograph, bone scan, CT or MRI and assessed according to RECIST v1.1, with at least 2 bone metastatic lesions on screening investigations performed at least 6 weeks prior to confirmation of eligibility
3.Measurable disease by RECIST 1.1 (including bone scans – see above)

1.Presence of other currently active (diagnosis within the last 5 years) malignancy (except treated non-melanoma skin cancer (basal or squamous), carcinoma in situ of cervix and superficial bladder cancers).
2.External beam radiotherapy within 4 weeks of confirmation of eligibility and starting treatment.
3.Past medical history of autoimmune disorders or organ transplant including but not limited to myasthenia gravis,myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, poorly controlled type 1 diabetes, vascular thrombosis associated with antiphospholipid syndrome, Wegener’s granulomatosis, Sjögren’s syndrome, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis

5.Active hepatitis B or hepatitis C. Patients with past hepatitis B virus (HBV) infection or resolved HBV infection (defined as having a negative HBsAg test and a positive antibody to hepatitis B core antigen [anti-HBc] antibody test) are eligible. Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase chain reaction (PCR) is negative for HCV RNA. Testing must be performed within 12 months prior to confirmation of eligibility.
6.HIV positive tested within 12 months prior to confirmation of eligibility.
7.Active tuberculosis based on clinical findings.
8.Receipt of an active live vaccine within 4 weeks of confirmation of eligibility and starting treatment.

10.Requirement for ongoing steroids in the context of active/symptomatic brain/leptomeningeal metastases.
11.Presence of imminent or established spinal cord compression based on clinical findings and/or MRI
12.Known history of clinically significant cardiac disease as documented in the medical records
13.Positive pregnancy test at eligibility assessment for women of childbearing potential or breast-feeding women
14.Known hypersensitivity to any of the excipients of avelumab or radium-223 as documented in the medical records
15.Inability to tolerate antihistamine or antipyretic (e.g. paracetamol) as documented in the medical records
16.Coagulation dysfunction that is deemed by the investigator to be likely to interfere with trial treatment as identified by clotting panel (APTT and INR) within 12 months prior to confirmation of eligibility.
17.Thyroid dysfunction that is deemed by the investigator to be likely to interfere with trial treatment as identified by TSH, free T3 and free T4 within 6 months prior to confirmation of eligibility. Patients with a history of autoimmune-mediated hypothyroidism on a stable dose of thyroid replacement hormone are eligible.
18.Erythropoietin treatment within the 4 weeks prior to confirmation of eligibility and start of treatment
