Study of Pyrotinib in Patients With Human Epidermalgrowth Factor Receptor 2 (HER2) Positive Advanced Breast Cancer
- Registration Number
- NCT01937689
- Lead Sponsor
- Jiangsu HengRui Medicine Co., Ltd.
- Brief Summary
Pyrotinib is an oral tyrosine kinase inhibitor targeting both HER-1 and HER-2 receptors. This study is designed to evaluate the safety and tolerability of Pyrotinib in patients with HER2 positive advanced 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 and its metabolites
* To assess preliminary antitumor activity
* To determine preliminary regimen dose for phase II study
* To explore the relationship between biomarkers and the toxicity/efficacy of Pyrotinib.
