Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

T-DXd

Participants who choose to continue treatment with T-DXd may be enrolled. Participants who were on the comparator arm in the parent study will be provided the option to access the drug through standard of care (SoC) or other available options.

Participants will remain on their current dosage regimen of T-DXd as the last dose administered in the parent study, unless they experience an AE that requires dose reduction at the EOT of the parent study, in which case the starting dose in this study will be the next lower dose-level.

Group Type EXPERIMENTAL

T-DXd

Intervention Type DRUG

T-DXd (DS8201a) will be administered as an intravenous (IV) infusion, on Day 1 of each 21-day cycle according to the dosage regimens
