Clinical Trial Summary

To learn if the study drugs, tucatinib and adotrastuzumab emtansine (T-DM1), can help to control solid tumors that have spread to the brain.


Clinical Trial Description

Primary Objectives: ● To determine the intracranial antitumor activity of the tucatinib and ado-trastuzumab emtansine (T- bination per the modified Response Evaluation Criteria in Solid Tumors (mRECIST) in patients with huma Key Secondary Objectives: - To determine the intracranial antitumor activity of the tucatinib and T-DM1 combination per the Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria in patients with HER2-positive metastatic solid tumors and brain metastases. - To evaluate the duration of intracranial response of the tucatinib and T-DM1 combination in patients with HER2-positive metastatic solid tumors and brain metastases. Other Secondary Objectives: - To evaluate the safety and tolerability of the tucatinib and T-DM1 combination in patients with HER2-positive metastatic solid tumors and brain metastases. - To evaluate the systemic antitumor activity of the tucatinib and T-DM1 combination per the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 in patients with HER2-positive metastatic solid tumors and brain metastases. - To evaluate progression-free survival (PFS) in patients with HER2-positive metastatic solid tumors and brain metastases receiving the tucatinib and T-DM1 combination. - To evaluate overall survival (OS) in patients with HER2-positive metastatic solid tumors and brain metastases receiving the tucatinib and T-DM1 combination. - To evaluate the duration of response to the tucatinib and T-DM1 combination per the RECIST v1.1 in patients with HER2-positive metastatic solid tumors and brain metastases. - To evaluate the clinical benefit rate of the tucatinib and T-DM1 combination per the RECIST v1.1 in patients with HER2-positive metastatic solid tumors and brain metastases. Exploratory Objectives: - To assess the effects of the tucatinib and T-DM1 combination on cell proliferation and apoptosis. - To evaluate predictive and pharmacodynamic (PD) biomarkers of response and resistance to the tucatinib and T-DM1 combination. - To assess the effects of the tucatinib and T-DM1 combination on circulating-free DNA (cfDNA) dynamics. ;
