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.

Detailed Description

This is a phase I, open-label, single-dose study. The study aims to characterize the pharmacokinetics of CAZ-AVI and assess its safety and tolerability following a single IV dose given to hospitalized pediatric patients receiving systemic antibiotic therapy for suspected or confirmed infection. This study will include 4 cohorts, each consisting of at least 8 evaluable pediatric patients, aged ≥3 months to <18 years, who are hospitalized with infections.

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

3 months to 17 years (CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  1. Written informed consent will be obtained from parent(s) or other legally acceptable representative(s), and informed assent from patient (if age appropriate) will be obtained
  2. Male or female children ages ≥3 months to <18 years.
  3. Hospitalized, receiving systemic antibiotic therapy for the treatment of a suspected or confirmed infection, and expected to require hospitalization until after the end of treatment (EOT) evaluations are completed.
  4. If female and has reached menarche, or has reached Tanner stage 3 breast development (even if not having reached menarche), the patient is practicing appropriate birth control or is sexually abstinent.
  5. Likely to survive the current illness or hospitalization.
  6. Sufficient intravascular access (peripheral or central) to receive study drug.

Exclusion Criteria:

  1. History of hypersensitivity reactions to carbapenems, cephalosporins, penicillin, other β-lactam antibiotics.
  2. If female, currently pregnant or breast feeding or has a positive serum β-human chorionic gonadotropin (β-hCG) pregnancy test.
  3. Receipt of a blood or blood component (e.g., red blood cells, fresh frozen plasma, platelets) transfusion during the 24-hour period before enrolment.
  4. BMI outside the range (below the 5th percentile or above the 85th percentile) for height, age, and weight except for children <2 years of age.
  5. Babies born prior to 37 weeks gestation (cohort 4 only).

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
Pharmacokinetic Parameters of Avibactam and Ceftazidime for Cohort 1 and 2: AUC
Time Frame: Day 1
Key PK parameters were prespecified to be calculated for cohorts 1 and 2. For cohorts 3 and 4 (where children were <6 years of age), sparse sampling scheme was used for PK samples to limit the volume of blood required. PK parameters cannot be derived from these sparse PK samples without population PK analysis. Thus the PK is not described here, but will be reported in a separate population PK report.
Day 1
Pharmacokinetic Parameters of Avibactam and Ceftazidime for Cohort 1 and 2: Cmax
Time Frame: Day 1
Key PK parameters are shown for cohorts 1 and 2. For cohorts 3 and 4 (where children were <6 years of age), sparse sampling scheme was used for PK samples to limit the volume of blood required. PK parameters cannot be derived from these sparse PK samples without population PK analysis. Thus the PK is not described here, but will be reported in a separate population PK report.
