Purpose
The main objective of this study is to test the safety and effectiveness of DS-8201a for
participants with HER2-expressing advanced colorectal cancer.
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.
Trial Arms
Name | Type | Description | Interventions |

DS-8201a Cohort A | Experimental | Cohort A is comprised of participants with HER2-positive (IHC 3+ or IHC 2+/ISH +) who will receive DS-8201a once every 3 weeks
Enrollment to this cohort was closed and this cohort is active until study completion. | |
DS-8201a Cohort B | Experimental | Cohort B is comprised of participants with HER2 IHC 2+/ISH - who will receive DS-8201a once every 3 weeks
This cohort is active. | |
DS-8201a Cohort C | Experimental | Cohort C is comprised of participants with HER2 IHC 1+ who will receive DS-8201a once every 3 weeks
Enrollment to this cohort was closed and this cohort is active until study completion. | |
