Experimental: dose escalation then expansion
Dose escalation of this study will follow a 3+3 study design with a starting intravenous (IV) dose of 0.1 mg/kg. Six dose levels are planned: level 1,0.1 mg/kg; level 2,0.3 mg/kg; level 3, 1.0 mg/kg; level 4,3.0 mg/kg; level 5,10 mg/kg; level 6,20 mg/kg.
Dose Expansion - Up to 20 subjects will be enrolled and treated at the dose determined in Dose Escalation arm.
- number of participants experiencing dose limiting toxicities [ Time Frame: day 1 through day 28 ]to investigate the safety of DS-8895a reporting on frequency and seriousness of treatment emergent adverse events
- number of participants experiencing clinical or laboratory adverse events [ Time Frame: from start of treatment to end of treatment, on expected average 12 weeks ]to investigate the safety of DS-8895a reporting on frequency and seriousness of treatment emergent adverse events
- serum pharmacokinetics of DS-8895a [ Time Frame: Cycle 1 - days 1, 2, 4, 8 and 15; Cycle 2-days 1, 2, 4, 8 and 15; Cycle 3 and on- days 1; end of study; 45 days post last dose ]pharmacokinetics (Area Under the Curve-AUC, Terminal Elimination half-life-t1/2, Total Body Clearance) of DS-8895a in Japanese subjects with advanced solid tumors, and also to investigate the recommended dose of DS-8895a for subsequent clinical studies
- level of anti-DS-8895a (HAHA) antibody [ Time Frame: Cycle 1 days 1 and 15; Cycle 2 day 1; end of study; 45 days post-last-dose ]Human anti-human antibody (HAHA) profile for DS-8895a [Time Frame: Cycle 1 - days 1, and 15; Cycle 2 and on - days 1; end of study; 45 days post last dose] The presence of HAHA (anti-DS-8895a neutralizing antibody) in serum will be assessed"
- disease control rate [ Time Frame: every 6 weeks ]proportion of subjects with the best overall response of stable disease or better will be measured every 6 weeks until study drug discontinued.
- pharmacodynamic effects in blood [ Time Frame: day 1 and 2 ]effects on blood will be determined at day 1 and 2 of each cycle
- pharmacodynamic effects in tumors [ Time Frame: baseline and day 1 of cycle 2 ]effects on tumor cells will be determined at baseline and day 1 of cycle 2
- objective response rate [ Time Frame: every 6 weeks ]sum of complete response and partial response rates measured every 6 weeks until study drug discontinuation
