Brief Summary:
The main objective of this study is to test the safety and effectiveness of DS-8201a for participants with HER2-expressing advanced colorectal cancer.

Condition or disease Intervention/treatment Phase
Colorectal Neoplasm Drug: DS-8201a Phase 2

Detailed Description:

At study start, only Cohort A is active.

If, and when, Cohort B and C become active depends on the assessment of benefit and risk observed in the program.

The sponsor will inform the investigators if, and when, Cohort B and C are active.

Primary Outcome Measures :
  1. Objective response rate (ORR) per imaging assessment [ Time Frame: from Cycle 1 Day 1 through disease progression (within 18 months) ]
    Percentage of participants with objective response per independent central imaging facility review based on Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 in Cohort A


Secondary Outcome Measures :
  1. Progression-free survival [ Time Frame: within 18 months ]
    Percentage of participants still alive without the disease getting worse

  2. Overall survival (OS) [ Time Frame: at 18 months ]
    Percentage of participants still alive

  3. Duration of response [ Time Frame: within 18 months ]
    Length of time response continued

  4. Disease control rate (DCR) [ Time Frame: within 18 months ]
    Percentage of participants with controlled disease

  5. ORR assessed by the investigator based on RECIST version 1.1 [ Time Frame: within 18 months ]
    Percentage of participants with objective response as assessed by the investigator, based on RECIST version 1.1

  6. Maximum serum/plasma concentration (Cmax) [ Time Frame: within 21 days ]
    Categories: DS-8201a, total anti-HER2 antibody, and MAAA-1181a

  7. Time to Cmax (Tmax) [ Time Frame: within 21 days ]
    Categories: DS-8201a, total anti-HER2 antibody, and MAAA-1181a

  8. Area under the concentration-time curve (AUC) from dosing until the last quantifiable concentration (AUClast) [ Time Frame: within 21 days ]
    Categories: DS-8201a, total anti-HER2 antibody, and MAAA-1181a

  9. AUC from the time of dosing until day 21 (AUC0-21d) [ Time Frame: at Day 21 ]
    Categories: DS-8201a, total anti-HER2 antibody, and MAAA-1181a
