Relationship Between Different Administration Regimens of Ceftazidime/Avibactam and Clinical Outcomes

July 29, 2024 updated by: The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School

Relationship Between Different Administration Regimens of Ceftazidime/Avibactam and Clinical Outcomes in Patients With Severe Infection: a Multicenter, Prospective, Randomized Controlled Study

Ceftazidime/avibactam (CAZ/AVI) is a new β-lactam drug, which has good antibacterial effect against carbapenem resistant enterobacter. However, previous studies found that CAZ/AVI had a low PK/PD compliance rate after the recommended dose of the drug instructions.Therefore, this study was intended to explore the clinical efficacy of different administration schedules of CAZ/AVI for patients with severe infection, and further analyze the correlation between CAZ/AVI PK/PD parameters and clinical efficacy and adverse reactions.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  1. Main purpose The main objective of this study was to verify that the clinical efficacy of treatment group (load dose of 2.5g, then continuous infusion of 2.5gQ8h, the dose can be adjusted according to renal function) with severe infection was superior to that of the control group (standard dose and administration regimen of ceftazidime/avibactam, i.e. 2.5gQ8h, 2h infusion).Dose can be adjusted according to renal function).
  2. Secondary purpose (1) To investigate the relationship between different administration regimens and bacterial clearance and 28-d mortality (2) To explore the correlation between different dosing regimens and PK/PD compliance rate (3) To explore the correlation between different administration regimens and adverse drug reactions

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

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 effective rate
Time Frame: 14 days
According to the Technical Guidelines for Clinical Trials of Antimicrobial Drugs, clinical efficacy is defined as: (1) effective: symptoms, signs, pathogenic microbiology and various tests and examination indicators are significantly improved;(2) Ineffective: the patient's condition has not improved or worsened, and other antibacterial drugs need to be replaced.Effective rate = Number of effective cases/total cases x 100%.
14 days

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
Bacterial removal
Time Frame: 14 days
Defined as clearance or change of existing bacteria within two weeks of medication.
14 days
28-d mortality
Time Frame: 28 days
Defined as whether a patient died at 28-d after follow-up.28-d Mortality rate = Number of deaths/group size x 100%.
28 days
PK/PD compliance rate
Time Frame: 14 days
PK/PD compliance rate = number of qualified persons/number of groups × 100%.
