简要总结
This phase II trial studies how well T-DMI with or without abemaciclib works for the treatment of HER2-positive breast cancer that has spread to other places in the body (metastatic). T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug called DM1. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers DM1 to kill them. Abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving T-DM1 and abemaciclib may work better in treating patients with breast cancer compared to T-DM1 alone.
详细描述
PRIMARY OBJECTIVES:
I. To assess whether progression-free survival (PFS) is improved with the addition of abemaciclib to trastuzumab emtansine (T-DM1) for patients with estrogen receptor positive (ER+)HER2-positive advanced or metastatic breast cancer who progressed on treatment with a taxane, trastuzumab and pertuzumab (Cohort 1).
II. To assess whether progression-free survival (PFS) is improved with the addition of abemaciclib to T-DM1 for patients with estrogen receptor negative (ER-) HER2-positive advanced or metastatic breast cancer who progressed on treatment with a taxane, trastuzumab and pertuzumab (Cohort 2).
SECONDARY OBJECTIVES:
I. To assess the safety and tolerability of each treatment regimen. II. To assess overall survival (OS) and objective response rate (ORR) of each treatment regimen.

主要结局
Progression-free survival (PFS)
时间窗: The time elapsed between treatment initiation and tumor progression or death from any cause, assessed up to 5 years
