Intervention model description: To observe the effect of efavirenz on the pharmacokinetics of pyrotinib and to evaluate the safety of pyrotinib, efavirenz and their coadministration in Chinese healthy subjects. The subjects will take pyrotinib at first single dose, then washout period, and take it at second single dose after multiple administration of efavirenz to get a full induction condition.
Primary purpose: TREATMENT

Brief summary: This drug-drug interaction (DDI) study had been designed to investigate the effect of a moderate CYP 3A inducer efavirenz on the pharmacokinetics of maleate pyrotinib in Chinese healthy volunteers.
