Participant Flow

323 subjects were screened, of whom 90 subjects were screening failures, and a total of 233 subjects were enrolled. 1 subject was enrolled but not dosed due to receiving prohibited concomitant medications during surgery, therefore a total of 232 subjects were administered at least one dose of the study drug. 17 subjects discontinued from the study, including 14 discontinuations during the treatment period, and 3 discontinuations during the follow-up period. 215 subjects completed the full study
