Complicated intra-abdominal infections (cIAIs), often caused by multidrug-resistant bacteria such as carbapenem-resistant
This is a multicenter, single-blind, parallel randomized controlled trial. Adult patients in the ICU with complex abdominal infections who meet the eligibility criteria will be included. The main outcome is the all-cause 30-day mortality of patients in clinically evaluable and microbiologically evaluable populations. Secondary outcomes include the proportion of total responsive patients in the clinically evaluable population at the end of treatment and test of cure visits; the proportion of total responsive patients in the microbiologically evaluable population at the end of treatment and test of cure visits; and ICU hospitalization time and costs. Safety assessments include the incidence of various adverse events and changes in clinical laboratory test results. The subjects will be randomly assigned to receive treatment with either eravacycline or tigecycline at a 1:1 ratio. The all-cause mortality rates of patients treated with eravacycline and TGC were 17.7 and 18.7%, respectively, with an estimated actual mortality rate of 0.95. A total sample size of 262 subjects is required to reach 80% power with an
