A Drug-drug Interaction Study of Famitinib Malate With a Proton Pump Inhibitor in Healthy Adult Subjects

A Single-centre, Single-arm, Open-label and Fixed-sequence Study to Evaluate the Effect of Omeprazole on Pharmacokinetics of Famitinib Malate in Healthy Adult Subjects

The primary objective is to evaluate the effect of omeprazole on the pharmacokinetics of famitinib malate in healthy adult subjects.

The secondary objective is to evaluate the safety after famitinib malate alone or combined administration with omeprazole in healthy adult subjects.
