Effect of Low-fat Diet on the Pharmacokinetics of Pyrotinib in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
The primary objective of the study is to evaluate the effect of low-fat diet on pharmacokinetics of healthy Chinese adult participants after oral administration of pyrotinib maleate tablets. The secondary objective of the study is to evaluate the safety of single dose of pyrotinib orally in healthy participants.
