Study Completion Date: July 4, 2017
Primary Completion Date: April 28, 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BAY94-9343

Cohort 1: Safety, tolerability and PK of 4.5 mg/kg dose given Q3W. Proceeding to Cohort 2 or not will be decided based on both safety variables during Cycle 1 (21 days) of 3 to 6 subjects in Cohort 1 and PK obtained from Cycle 1 (at least Day 1 to Day 5).

Cohort 2: Safety, tolerability and PK of 6.5 mg/kg dose given Q3W. Whether recruitment will be continued up to 9 subjects for Cohort 2 or not will be decided based on safety variables during Cycle 1 (21 days) of the first 3 subjects in Cohort 2. The safety and tolerability of 6.5 mg/kg will be assessed based on the data of 9 subjects during Cycle 1 in Cohort 2, and considering long term toxicity, the safety and tolerability of BAY94-9343 will be assessed all safety data by the end of 3 cycles in Cohort 2.

Drug: BAY94-9343
Cohort 1: 4.5 mg/kg of BAY 94-9343 at Q3W dose regimen. Cohort 2: 6.5 mg/kg of BAY 94-9343 at Q3W dose regimen.
