To Explore the Pharmacokinetics and Relative Bioavailability of Sulfatinib Capsules in Two Different Manufacturers

27-30 Chinese male healthy volunteers will be enrolled to assess the pharmacokinetic profile and relative bioavailability of 300 mg (50 mg x 6) Sulfatinib capsules of single dose orally in two different manufacturers after breakfast. All subjects are required to collect PK blood samples before and after administration at the following time points: within 1 hour before administration, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 12, 24, 36, 48, 72, 96 hours after administration (16 times point), each collection of venous blood is 2mL.
