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 Baysian 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.

Secondary Outcome Measures :

3. Change in the time of maximum plasma concentration Tmax of DS-8201a [ Time Frame: from first dose to Day 45 ]
   time of maximum plasma concentration Tmax at Cycle 1, Days 1, 2, 4, 8, 15; Cycles 2, 4, 6, and 8, Day 1; Cycle 3, Days 1, 8, 15.
4. Change in the total anti-HER2 antibody [ Time Frame: from first dose to Day 45 ]
   Cycle 1, Days 1, 2, 4, 8, 15; Cycles 2, 4, 6, and 8, Day 1; Cycle 3, Days 1, 8, 15.
5. Change in MAAA-1181 level [ Time Frame: from first dose to Day 45 ]
   determine the change in MAAA-1181 level from first dose to Day 45 at Cycle 1, Days 1, 2, 4, 8, 15; Cycles 2, 4, 6, and 8, Day 1; Cycle 3, Days 1, 8, 15.
