Summary
This study is intended to test an experimental new drug called, EMD 525797 (Study Drug). This drug is not yet approved for sale and has only been tested in a small number of people to date (prior to this study starting another research study was carried out involving 37 healthy volunteers receiving the Study Drug). Until more is known about this Study Drug, it can only be used in research studies.
This research study is planned to answer important questions about how the Study Drug is tolerated and how it may work in patients with prostate cancer with bone metastases.
This is a small study which is expected to include 24 patients, and will be conducted in approximately 3 hospitals in Germany and 1 hospital in Brussels, Belgium. The study will last until the last patient has had their last study visit which is expected to be about 18 months in total.

Eligibility Criteria
Inclusion Criteria
- Provision of signed written informed consent
- Age superior or equal to 18 years
- Subjects with histological or cytologically proven prostate cancer with evidence of bone metastases on bone scans or CT / MRI after prior chemotherapy with e.g. taxane or mitoxantrone Patients should have undergone bilateral orchiectomy or should be on continuous androgen deprivation therapy with a gonadotropin releasing hormone agonist or antagonist and should have stopped any anti-androgen therapy for at least 4 weeks before inclusion in the study. Patients should be either on stable (i.e., since at least 3 months) ongoing therapy with a bisphosphonate or without any bisphosphonate therapy. Initiation of a bisphosphonate therapy within this time period prior the study or during the study is not allowed. Total serum testosterone should be less than 50 ng/dL or 1.7 nmol/L.

- Adequate hepatic function defined by total bilirubin level less than or equal to 1.5 times the upper limit of normal (ULN), and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels less than or equal to 2.5 x ULN; or, for subjects with documented metastatic disease to the liver, AST and ALT levels less than or equal to 5 x ULN.
- Adequate renal function defined by serum creatinine less than 1.5 mg/dL.
- Effective contraception. If the risk of conception exists, pregnancy has to be avoided during the study (SCR to EOS) as well as during at least 3 month after last dosing using an effective contraception method (e.g. double barrier method)

- Acute pathologic fracture, spinal cord progression, hypercalcemia (within 4 weeks period prior to screening).
- Radiotherapy to bone lesions, orthopaedic surgery, or any investigational drug in the 30 days before the start of treatment in this study and during treatment period, and/or biopsies involving bone within 2 weeks before the start of treatment in this study.
- Supraphysiologic doses of steroids (defined as superior or equal to 7.5 mg of prednisone equivalents per day).
- Previous treatment with anti-integrin therapy.
- Confirmed or clinically suspected brain metastases.
- Known hypersensitivity reactions to any of the components of the study medication.
- History of allergic reactions to other monoclonal antibody (mAb) therapy.
- Uncontrolled hypertension (systolic greater or equal to 160 mmHg, diastolic greater than or equal to 100 mmHg).
- Current history of chronic daily aspirin therapy (ASS at doses inferior or equal to 100 mg is permitted), bleeding disorders and/or history of thromboembolic events (history of superficial thrombophlebitis is not an exclusion criterion); thrombolytics or oral or parenteral anticoagulants within 10 days prior to study start and during treatment period.
