Details and patient eligibility

About

Pyrotinib is an oral tyrosine kinase inhibitor targeting both EGFR and HER-2 receptors. This study is designed to evaluate the safety and tolerability of Pyrotinib in combination with capecitabine in patients with HER2 positive metastatic breast cancer:

To evaluate the safety and tolerability of pyrotinib, and the maximum tolerated dose (MTD) To determine the dose-limiting toxicity (DLT) To determine the pharmacokinetic profile of Pyrotinib To assess preliminary antitumor activity To determine preliminary regimen dose for phase II study
