About this study

Official title: A Phase III Non-randomized, Non-controlled, Open Label Clinical Trial to Study the Safety and Efficacy of Imipenem/Cilastatin/Relebactam (IMI/REL [MK-7655A]) in Japanese Subjects With Complicated Intra-Abdominal Infection (cIAI) or Complicated Urinary Tract Infection (cUTI)

The study will evaluate the efficacy and safety of imipenem+cilastatin/relebactam (IMI/REL, MK-7655A) in Japanese participants with complicated intra-abdominal infection (cIAI) or complicated urinary tract infection (cUTI).

Being tested

Receives: Drug: Imipenem+Cilastatin/Relebactam

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Experiencing ≥1 Adverse Events (AE)

    The percentage of participants experiencing ≥1 AE was calculated. An AE was defined as any unfavorable and unintended sign, symptom, or disease (new or worsening) temporally associated with the use of study therapy, regardless of whether or not a causal relationship with the study therapy could be determined.

    Measured: Up to 28 days

  2. Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event (AE)

    The percentage of participants who discontinued from study medication due to an adverse event was calculated. An AE was defined as any unfavorable and unintended sign, symptom, or disease (new or worsening) temporally associated with the use of study therapy, regardless of whether or not a causal relationship with the study therapy could be determined.

    Measured: Up to 14 days (End of Therapy Visit)

  3. Percentage of Complicated Intra-Abdominal Infection (cIAI) Participants With Favorable Clinical Response at End of Therapy Visit

    The percentage of participants with cIAI who display a favorable clinical response at End of Therapy visit was presented. Per protocol, a subset of the cIAI/cUTI study arm was analyzed: only participants with cIAI were evaluated because clinical response is primarily relevant to cIAI. Favorable clinical response is a rating of "cure" or "improved" as determined by the investigator at the End of Therapy Visit. "Cure" is defined as: all pretherapy signs and symptoms of the index infection(s) have resolved (or returned to preinfection status) AND no additional intravenous antibiotic therapy is required AND no unplanned surgical or percutaneous drainage procedures have been performed. "Improved" is defined as: All or most pretherapy signs and symptoms of the index infection(s) have improved or resolved (or returned to preinfection status) AND no additional intravenous antibiotic therapy is required AND no unplanned surgical or percutaneous drainage procedures have been performed.

    Measured: Between Day 5 and Day 14 (End of Therapy Visit)

  4. Percentage of Complicated Urinary Tract Infection (cUTI) Participants With Favorable Overall Microbiological Response at End of Therapy Visit

    The percentage of participants with cUTI who display a favorable Overall Microbiological Response at the End of Therapy visit was calculated. Per protocol, only a subset of the cIAI/cUTI study arm was analyzed: only participants with cUTI were evaluated because the microbiological response evaluation is primarily relevant to cUTI. A favorable Overall Microbiological Response is defined as a urine culture taken at the End of Therapy Visit showing eradication (e.g., ≥10^5 CFU/mL is reduced to <10^4 CFU/mL) of all uropathogens found at study entry.

    Measured: Between Day 5 and Day 14 (End of Therapy Visit)

Secondary outcomes (2)
  1. Percentage of Complicated Intra-Abdominal Infection (cIAI) Participants With Favorable Clinical Response at Test of Cure Visit

    The percentage of participants with cIAI who display a favorable Clinical Response at the Test of Cure visit was calculated. Per protocol, only a subset of the cIAI/cUTI study arm was analyzed: only participants with cIAI were evaluated because the clinical response evaluation is primarily relevant to cIAI. A favorable clinical response is a rating of "cure" as determined by the investigator at the Test of Cure Visit. "Cure" is defined as: all pretherapy signs and symptoms of the index infection(s) have resolved (or returned to "preinfection status") AND no additional intravenous antibiotic therapy is required AND no unplanned surgical or percutaneous drainage procedures have been performed.

    Measured: Between Day 10 and Day 23 (Test of Cure Visit)

  2. Percentage of Complicated Urinary Tract Infection (cUTI) Participants With Favorable Overall Microbiological Response at Test of Cure Visit

    The percentage of participants with cUTI who display a favorable Overall Microbiological Response at the Test of Cure visit was calculated. Per protocol, only a subset of the cIAI/cUTI study arm was analyzed: only participants with cUTI were evaluated because the microbiological response evaluation is primarily relevant to cUTI. A favorable Overall Microbiological Response is defined as a urine culture taken at the Test of Cure visit still showing eradication (e.g., ≥10^5 CFU/mL is reduced to <10^4 CFU/mL) of all uropathogens found at study entry.

    Measured: Between Day 10 and Day 23 (Test of Cure Visit)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Imipenem+Cilastatin/Relebactam in people with Complicated Intra-abdominal Infection and Complicated Urinary Tract Infection, run by Merck Sharp & Dohme LLC at 29 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 29 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Sep 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants Experiencing ≥1 Adverse Events (AE) (time frame: Up to 28 days). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03293485, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2021.
