In each group, 31% (32 of 102) and 38% (54 of 141) of patients, respectively, had baseline brain metastases and 53% (17 of 32) and 44% (24 of 54), respectively, received prior brain metastasis treatment. In patients with and without brain metastases, systemic confirmed objective response rates (ORRs) were 47% (15 of 32; 95% CI, 29%-65%) and 50% (35 of 70; 95% CI, 38%-62%), respectively, with the T-DXd 5.4-mg\/kg dose, and 50% (27 of 54; 95% CI, 36%-64%) and 59% (51 of 87; 95% CI, 48%-69%) with the T-DXd 6.4-mg\/kg dose. Median progression-free survival was 7.1 (95% CI, 5.5-9.7) months in the T-DXd 5.4-mg\/kg dose group and 7.1 (95% CI, 4.5-9.6) months in the T-DXd 6.4-mg\/kg dose group of patients with baseline brain metastases. Among patients with measurable baseline brain metastases, intracranial confirmed ORRs were 50% (7 of 14; 95% CI, 23%-77%) with the T-DXd 5.4-mg\/kg dose and 30% (9 of 30; 95% CI, 15%-49%) with the T-DXd 6.4-mg\/kg dose.
