E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to evaluate whether EMD 525797 administered as 1-hour intravenous (i.v.) infusion every 3 weeks is superior to placebo in terms of progression free survival (PFS) time in subjects with asymptomatic or mildly symptomatic mCRPC. |
|
E.2.2 | Secondary objectives of the trial |
To further evaluate the efficacy of EMD 525797 - To further characterize the safety profile of EMD 525797 - To further evaluate the pharmacokinetic (PK) profile of EMD 525797 - To explore the relationship between number and/or changes of numbers of circulating tumor cells (CTCs) and the clinical outcome (e.g., primary and secondary endpoints). |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects with asymptomatic or mildly symptomatic mCRPC with progression of bone metastasis (new bone lesion(s)) by bone scan within 42 days prior to Screening will be eligible for this trial.

Uncontrolled hypertension defined as systolic blood pressure ≥160 mmHg and/or diastolic blood pressure ≥100 mmHg under resting conditions for at least 5 minutes. 12. Chronic daily acetylsalicylic acid (ASS) therapy at doses >100 mg. 13. Bleeding disorders and/or history of thromboembolic events (history of superficial thrombophlebitis is not an exclusion criterion). 14. Treatment with thrombolytics or oral or parenteral anticoagulants within 10 days prior to trial treatment. 15. Severe peripheral vascular disease or ulceration; unstable angina pectoris, or myocardial infarction within 6 months before start of trial treatment, clinically significant abnormal electrocardiogram (ECG) at screening. 16. Known alcohol or drug abuse. 17. Participation in another clinical trial within 30 days before start of trial treatment. 18. Dementia, altered mental status, or any psychiatric condition that would prohibit the understanding or rendering of informed consent. 19. Hepatitis B or C, human immunodeficiency virus (HIV) infection, active or chronic. 20. Legal incapacity or limited legal capacity. 21. All other significant diseases which, in the opinion of the Investigator, might impair the subject’s tolerance of trial treatment. 22. Other malignancy if treatment has not been completed within 2 years before start of trial treatment. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint of the trial is PFS defined as the time from the date of randomization until the first documented sign of objective radiographic disease progression or death from any cause. Objective radiographic disease progression is defined as one of the following conditions: - Bone lesion progression (appearance of 2 or more new bone lesions compared to baseline) assessed with bone scintigraphy, which should be confirmed by bone scintigraphy 6 weeks later if there are no symptoms. Assessments based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.0 modified according to the Prostate Cancer Working Group 2 (PCWG-2). - Soft-tissue lesion progression according to RECIST 1.0 assessed with CT scans. - Presence of skeletal events defined as cord compression or fracture documented via a scheduled or an unscheduled radiographic assessment triggered by increasing pain (needing opioids or radiation) or other signs and/or symptoms at Investigator discretion. |
