Reviewer's view of the efficacy data
FDA: relebactam restores imipenem activity in vivo against non-susceptible isolates and penetrates pulmonary ELF
“Consistent with the in vitro studies, REL has the ability to restore the antibacterial activity of imipenem in vivo against isolates that are not susceptible to imipenem. In vivo models also suggest that REL penetrates pulmonary ELF.”
