A Comparative Phase IV Study Evaluating Efficacy & Safety Of Magnex(Cefoperazone-Sulbactam) In Intraabdominal Infections

December 1, 2008 updated by: Pfizer

A Randomized, Open Label, Multicentre Phase Iv Study To Evaluate The Efficacy And Safety Of Magnex (Cefoperazone-Sulbactam) In Comparison With Ceftazidime Plus Amikacin And Metronidazole In The Treatment Of Intra-Abdominal Infections

Intra-abdominal infections are often polymicrobial, and include aerobic as well as anaerobic bacteria. Antibiotics used in intra-abdominal infections should aim to cover organisms such as Enterobacteriaceae and Bacteroides fragilis, which are the commonest organisms known to cause such infections. Combinations of a third-generation cephalosporin, an aminoglycoside and metronidazole are often used to treat such infections in surgical settings. An alternative to such combinations is the use of a beta lactam - beta lactamase inhibitor combination. Magnex (cefoperazone- sulbactam) is one such combination, which has been shown to be as effective as a standard multidrug regimen such as gentamicin and clindamycin in the management of intra-abdominal infections. The combination of ceftazidime, amikacin and metronidazole has been chosen as a comparator regimen because of its broad coverage of Gram-negative and anaerobic organisms found in such conditions.

Study Overview

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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

12 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Male or female subjects aged greater or equal to 12 years
  • Intra-abdominal infection documented by laparotomy or laparoscopy or percutaneous aspiration within 24 hours prior to screening
  • Presence of at least three of the following five indicators consistent with intra-abdominal infections (Fever, leucocytosis, abdominal symptoms, abdominal signs, radiological evaluation)
  • Written informed consent obtained

Exclusion Criteria:

  • Rapidly progressive illness or critically ill subjects
  • Pregnant or lactating women, or women of childbearing potential not using an effective method of contraception.
  • Treatment with a presumably effective systemic antimicrobial agent for >24 hours within a 72 hour period prior to study entry unless the subject did not sufficiently respond to the treatment (as judged by the investigator)

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
Proportion of clinical efficacy-evaluable subjects who present with continued resolution at the 30-day follow-up visit.
Adverse events as observed by the investigator or volunteered as responses to unsolicited and non-leading questions.
Vital signs including systolic and diastolic blood pressures, pulse rate and respiratory rate.
Physical examination findings.

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
The proportion of clinical efficacy
evaluable subjects who are classified as having a clinical outcome of success or improvement at the end of study treatment;
proportion of microbiological efficacy-evaluable subjects who have a successful microbiological outcome
success or presumed success) at the end of study treatment,
Total duration of study treatment
Comparison of pharmaco-economic data (cost effectiveness) for cefoperazone- sulbactam versus the combination of ceftazidime - amikacin - metronidazole.
