The primary objective of the trial is to evaluate the clinical anti-tumor activity of EMD 525797 administered as 1-hour intravenous infusion every 3 weeks in terms of progression free survival (PFS) time in subjects with asymptomatic or mildly symptomatic metastatic castrate-resistant prostate cancer (mCRPC).

Primary Outcome Measures:
  • Clinical anti-tumor activity assessed as progression free survival (PFS) [ Time Frame: up to 3 months after last subject randomized ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Overall survival [ Time Frame: anticipated average time frame of 2 years ] [ Designated as safety issue: No ]
  • Time to progression [ Time Frame: anticipated average time frame of 2 years ] [ Designated as safety issue: Yes ]
  • PSA response [ Time Frame: anticipated average time frame of 2 years ] [ Designated as safety issue: No ]
  • Population pharmacokinetics data will be used to study of the sources of variability in drug concentrations among individuals which may have an impact on efficacy or safety of EMD 525797 such as CL (L/h) and Vd (L) [ Time Frame: anticipated average time frame of 2 years ] [ Designated as safety issue: Yes ]
  • Number of treatment emergent adverse events [ Time Frame: anticipated average time frame of 2 years ] [ Designated as safety issue: Yes ]
  • To explore the relationship between number and/or changes of numbers of biomarker and the clinical outcome [ Time Frame: anticipated average time frame of 2 years ] [ Designated as safety issue: No ]

Enrollment: 180
Study Start Date: April 2011
Estimated Study Completion Date: September 2014
Estimated Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1 Drug: EMD 525797
All eligible subjects will receive EMD 525797 and will be given intravenous (1500 mg/1h infusion) every 3 weeks until disease progression.
Experimental: Arm 2 Drug: EMD 525797
All eligible subjects will receive EMD 525797 and will be given intravenous (750 mg/1h infusion) every 3 weeks until disease progression.
Placebo Comparator: Arm 3 Other: Placebo
The trial will be controlled using placebo (a 0.9% sodium chloride solution) plus Standard of care. If subjects experience radiographic progressive disease (PD) without symptoms (asymptomatic) or with mild symptoms (mildly symptomatic) neither requiring opioid therapy nor chemotherapy, they will be allowed to receive open-label treatment with EMD 525797, 1500 mg after radiographic confirmation by bone scintigraphy 6 weeks later. Until this confirmation, treatment will be continued as scheduled.
