Summary
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

- Subjects that are unable to swallow tablets, or dysfunction of gastrointestinal
absorption.

- Less than 4 weeks from the last radiotherapy,chemotherapy,surgery,hermone
treatment,target therapy, or less than 6 weeks from the nitrosoureas or mitomycin
chemotherapy.

- Subjects with no efficacy during the previous treatment of capecitabine.

- Subjects with uncontrolled hypokalemia and hypomagnesemia before study entry.

- Subjects who can not interrupt the using of the drugs that may cause QT prolongation
during study.

- Subjects with intracranial lesions.

- Subjects with bone or skin as the only target lesion

- Treated or treating with HER2 tyrosine kinase inhibitors (TKIs) before study entry.

- Receiving any other antitumor therapy.

- Less than 4 weeks from the last clinical trial.

- Known history of hypersensitivity to pyrotinib、capecitabine or any of its components
or metabolites.

- Ongoing infection (determined by investigator).

congenital immunodeficiency disease, or history of organ transplantation.

- Subjects had any heart disease, including: (1) angina; (2) requiring medication or
clinically significant arrhythmia; (3) myocardial infarction; (4) heart failure; (5)
Any heart diseases judged by investigator as unsuitable to participate in the trial.

potential tested positive in baseline pregnancy test.

- Female patients of childbearing age that are reluctant to take effective contraceptive
measures throughout the trial period.

substantially increase the risk associated with the subject's participation in and
completion of the study. Examples include, but are not limited to,hypertension, severe
diabetes, or thyroid disease.
