Brief Summary:
This is an open-label, two-part, multiple study to evaluate the safety and tolerability of DS-8201a in patients with advanced solid malignant tumors.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors Drug: DS-8201a Phase 1

Detailed Description:
This study is one single group of participants in two periods. It is therefore not randomized. The dosage strength will change during the study but all participants will receive the same study drug DS-8201a. So the study is not a true 2 arm study, it is a 2 part study.

Arm Intervention/treatment
Experimental: Part 1 Dose escalation
Part 1 is a dose escalation to identify the Maximum Tolerated dose (MTD) or the recommended phase 2 dose of DS-8201a guided by the modified continuous reassessment method using a Bayesian logistic regression model following escalation with overdose control principal.
 Drug: DS-8201a
Experimental: Part 2 Dose expansion
Part 2 is a dose expansion to examine the safety and efficacy of DS-8201a and it is consist of multiple cohorts: in subjects with trastuzumab emtansine (T-DM1)-treated HER2 overexpressing breast cancer (Part 2a); trastuzumab-treated HER2 overexpressing gastric or gastroesophageal junction adenocarcinoma (Part 2b); HER2 low expressing breast cancer (Part 2c), and HER2 expressing other solid malignant tumor (Part 2d)
 Drug: DS-8201a


Outcome Measures

Primary Outcome Measures :
  1. Number of subjects experiencing adverse events [ Time Frame: Day 1 through 28 days after last dose ]
    frequency and seriousness of treatment emergent adverse events (TEAEs).

  2. Tumor response using RECIST version 1.1 throughout study [ Time Frame: from randomization date until disease progresses, whichever comes first, up to 30 months ]
    RECIST = Response Evaluation Criteria In Solid Tumors Assessment of tumor response is conducted every 6 weeks in the first 24 weeks and thereafter every 12 weeks until progressive disease to evaluate the efficacy of DS-8201a up to 30 months.
