Imipenem/Cilastatin/Relebactam (IMI/REL) in Treatment of CRE Infections
Stopped: Lack of enrollment
United States0Started 2021-06-07
Plain-language summary
This is an observation study comparing prospective use of Imipenem/Cilastatin/Relebactam (IMI/REL) to retrospective data using Meropenem/Vabobactam (MVB)and Ceftazidime/Avibactam CZA) in treatment of Klebsiella Producing Carbapenemase Enterobacteriaceae infections at a tertiary care hospital. The objectives of the study are to demonstrate successful treatment of KPC containing Enterobacteriaceae infections with IMI/REL including in bacteremia, and to analyze treatment outcomes in use of IMI/REL for KPC-producing infections compared to historical clinical outcome data with CZA and MVB use at the same institution.

Inclusion criteria
. Adult (\>18 years of age) patients with a KPC-producing CRE infection at any site except for isolated urinary source. Patients may be initially enrolled once identified with a CRE infection defined as resistance to any carbapenem. Any carbapenem resistance will provide an initial mechanism of identifying study eligible patients in accordance with our institutions definition of CRE for infection prevention purposes. As this study is specific for KPC-producing CRE inclusion in the study analysis will require confirmation of a KPC gene by molecular analysis of the isolate and subjects enrolled may be subsequently removed from study and excluded from analysis if molecular testing reveals their CRE isolate to be a non-KPC mechanism of resistance. Polymicrobial infections at same or different sites can also be included as long as additional gram-negative active agents aside from IMI/REL are not needed for treatment.
. Bacterial infection with Enterobacteriaceae excluding Morganellaceae
. Ability and willingness to give informed consent. A Legal authorized representative may be used when the patient is unable to provide informed consent.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Be the first episode of a CRE infection to be treated with IMI/REL. Previously treatment with IMI/REL for a KPC-containing Enterobacteriaceae infection will exclude patients from enrollment.
Exclusion criteria
. Receipt of more than 48 hours of effective antibiotic therapy against KPC containing infections (e.g. MVB, CZA) prior to first dose of IMI/REL being administered.
. Infections localized to urinary source alone (bloodstream infections from urinary source will be included)
. Infection with Morganellaceae
. Prior serious allergic reaction to carbapenem therapy
. Need for ongoing concomitant therapy with ganciclovir or valproic acid
. Need for ongoing concomitant therapy with another antibiotic active against gram negative pathogens. Concomitant therapy with Vancomycin, Daptomycin, Linezolid, Clindamycin, Fidaxomicin, Nafcillin, Metronidazole, and Rifaximin will be allowed but no other antibiotic agents.
. Pregnancy or ongoing breastfeeding. Women of childbearing age must test negative on a urine pregnancy test at time of screening for trial eligibility and remain either abstinent or use 2 forms of highly effective contraception for the duration of the IMI/REL administration during the study.
. Inability to comply with study protocol or remain hospitalized for duration of study.
