Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Study will include adult patient (male, female).
  • Patient age from 18 to 70 years.
  • Patient will be admitted to intensive care unit in study period (six months), who will receive intravenous colistin and meropenem or amikacin and meropenem as antimicrobial drug for treatment their MDR gram negative infection

Exclusion Criteria:

  • Patients are admitted to intensive care unit younger than 18 years or older than 70 years.
  • Patients are chronic kidney disease (CKD on hemodialysis or baseline creatinine clearance (crcl) < 10 ml/min (estimated by Cockcroft Gault equation).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: colistin and meropenem
50 patients received intravenous colistin 300 mg colistin base activity (CBA) as loading dose, followed by 2.5-5mg/kg/day of CBA in 2 divided doses as a maintenance dose and intravenous meropenem 2gm every 8hrs
Drug: Colistimethate sodium for injection, meropenem

Active Comparator: amikacin and meropenem
50 patients received intravenous amikacin 15 to 30 mg/kg once daily and intravenous meropenem 2gm every 8hrs
Drug: Amikacin Injection and meropenem
compare the efficacy and safety between combination of colistin and meropenem and combination of amikacin and meropenem for multi-drug-resistant gram-negative bacteria in Intensive Care Unit. In Beni- Suef University Hospital.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
clinical cure at 72 hours
Time Frame: 72 hours
Number of participants achieving clinical cure, defined as resolution of fever and improvement of the baseline signs and symptoms of infection without the need to change or escalate antibiotic therapy.
72 hours
Body temperature
Time Frame: 72 hours
Body temperature measured at baseline and 72 hours after initiation of antibiotic therapy.
72 hours
White blood cell count
Time Frame: 72 hours
White blood cell (WBC) count measured at baseline and 72 hours after initiation of antibiotic therapy.
72 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Serum creatinine level
Time Frame: 72 hours
Serum creatinine level measured at baseline and 72 hours after initiation of colistin plus meropenem or amikacin plus meropenem to assess renal function.
72 hours
14- day survival rate
Time Frame: 14 days
Number of participants who are alive 14 days after initiation of colistin plus meropenem or amikacin plus meropenem therapy.
14 days

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
