Primary Outcome Measures

Name	Time	Method
Number of Subjects With Dose-limiting Toxicities (DLTs)	Baseline up to Week 4	DLT was defined as any Grade 3 or 4 haematological or non-haematological toxicity occurring at any dose level until the end of Week 4, and suspected to be reasonably related to the investigational medicinal product by the Investigator and/or Sponsor. Toxicities not considered to be DLTs are as follows- Allergic reactions or anaphylaxis; any Grade 3 or 4 out-of-range laboratory values without any clinical correlate, which were reversible within 7 days, unless the Investigator decided this event is clinically significant. For this reason Grade 3 or 4 out-of-range laboratory values must be re-assessed within 7 days. In case the Investigator provides the subject any treatment(s) due to the out-of-range laboratory values, the event was regarded as a DLT.
Area Under the Curve From Time Zero to Last Quantifiable Concentration(AUC0-t) of EMD 525797: After Multiple Dose	Pre-dose, hour 1 (EOI), 4, 8, 24, 48, and 96 hours after start of infusion at Week 5	Area under the serum concentration-time curve from time zero to the last sampling time at which the concentration is at or above LLQ.
Total Body Clearance at Steady State (CLss) of EMD 525797	Pre-dose, hour 1 (EOI), 4, 8, 24, 48, and 96 hours after start of infusion at Week 5	Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood. CL of drug in serum was calculated as : CL= Dose/ AUC0-inf. Area under the serum concentration-time curve from time zero to infinity (AUC0-inf), calculated as AUC0-t + AUCextra. AUCextra represents an extrapolated value obtained by Clast / λz, where Clast is the calculated serum concentration at the last sampling time point at which the measured serum concentration is at or above LLQ and λz is the elimination rate constant.
Pharmacokinetics of EMD 525797 - Trough Values	Pre-dose, hour 1 (EOI), 4, 8, 24, 48, and 96 hours after start of infusion at Week 5	The observed serum concentration immediately before next dosing determined directly from the serum concentration-time profile of each subject (= trough concentration).

Apparent Volume of Distribution (Vz): After Single Dose	Pre-dose, hour 1 (EOI), 4, 8, 24, 48, and 96 hours after start of infusion at Week 1	Apparent volume of distribution during the terminal phase, calculated as Vz = Dose/AUC0-inf multiplied by elimination rate constant \[λz\]) following single dose. Area under the serum concentration-time curve from time zero to infinity, calculated (AUC0-inf) as AUC0-t + AUCextra. AUCextra represents an extrapolated value obtained by Clast / λz, where Clast is the calculated serum concentration at the last sampling time point at which the measured serum concentration is at or above LLQ and λz is the elimination rate constant. And the elimination rate constant obtained from linear regression of the terminal phase of the log transformed concentration-time data. A minimum of three points is required to calculate λz.
Apparent Volume of Distribution: After Multiple Dose	Pre-dose, hour 1 (EOI), 4, 8, 24, 48, and 96 hours after start of infusion at Week 5	Apparent volume of distribution during the terminal phase, calculated as Vz = Dose/(Area under the serum concentration-time curve within one complete dosing interval \[AUCtau\]\* λz) following multiple dose.

Average Serum Concentration at Steady State (Cav)	Pre-dose, EOI, 4, 8, 24, 48, and 96 hours after start of infusion at Week 5	The Cav was calculated by dividing the area under the serum concentration-time curve within one complete dosing interval (AUCtau) by the dosing interval (2 weeks or 336 hoursi.e. Cav =AUCtau/tau).
