Merino Trial Ampc

Listing a study does not mean it has been evaluated by the us.

Merino trial ampc. Previously randomised in the merino 3 trial or concurrently enrolled in another therapeutic antibiotic clinical trial blood culture isolate with in vitro resistance to either meropenem or ceftolozane tazobactam known either at time of enrolment or during the course of study treatment in which case the participant will be withdrawn. Merino trial this supplement contains the following items. Randomised controlled trial of meropenem versus piperacillin tazobactam for definitive treatment of bloodstream infections due to ceftriaxone non susceptible escherichia coliand klebsiella spp.

A total of 23 of 187 patients 123 randomized to piperacillin tazobactam. 478 women who were randomized appropriately received at least 1 dose of study drug and were included in the primary analysis population 378 997 completed the trial and were assessed for the primary outcome. Original protocol final protocol summary of changes.

The merino trial is the first randomized controlled trial to evaluate piperacillintazobactam versus meropenem for the definitive treatment of bsis caused by ceftriaxone not susceptible e coli or k pneumoniae that remained susceptible to piperacillintazobactam by current breakpoints.

A basal ampc b lactamase productionb increased transcription of ampc in the presence of an inducing b lactam antibiotic that increases cell wall degradation production to levels beyond the capacity of ampd cleavage.
