There are a total of 12 volunteers in each group with a similar male to female ratio. Groups 1 and 3 are single-arm study, all volunteers will receive the experimental drug ""KLA578-1 for Injection"" ; Group 2 is a randomized, two-treatment, two-period, crossover study, 12 volunteers will be randomized to TR sequence or RT sequence with 6 volunteers in each sequence. The experimental drug ""KLA578-1 for injection"" will be administered in the TR sequence of Period 1, the control drug ""Etopcoxib Tablets"" will be administered to the RT sequence. After 7 days of washing, the control drug ""Etocoxib Tablets"" will be administered in the TR sequence, and the experimental drug ""KLA578-1 for Injection"" will be administered in the RT sequence.
Part 2: This is a open-label, single-arm multiple dose study. A dose group is temporarily set up, with a total of 12 volunteers enrolled, and the male-to-female ratio will be similar. Volunteers will receive the experimental drug ""KLA578-1 for Injection"" 120 mg once daily (every 24 h ± 2 min with reference to the dosing time on D1) under fasting conditions (fasting for at least 10 hours) from D1 to D5; Drinking water is prohibited from 1 h before each dose to 1 h postdose, and fasted within 4 hours after dosing on D1 and D5."
