Trifluridine-tipiracil in previously treated patients with oestrogen receptor-positive, HER2-negative metastatic breast cancer (BOOG 2019-01 TIBET trial): a single-arm, multicentre, phase 2 trial.

ABSTRACT:

Background

Effective later-line chemotherapy treatment options are scarce for patients with metastatic breast cancer (MBC). Trifluridine-tipiracil has shown survival benefit in heavily pre-treated patients with metastatic colorectal and in gastric cancer refractory to a fluoropyrimidine. This study aimed to investigate the efficacy of trifluridine-tipiracil in a Western population of previously treated patients with oestrogen receptor (ER+), HER2- MBC to facilitate further optimization of this treatment strategy.

Methods

Adult patients at least 18 years old diagnosed with hormone receptor positive, HER2- receptor negative MBC with a performance status of 0 or 1 who have been treated with capecitabine in the metastatic setting and up to two other lines of chemotherapy, includ
