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 an open-label, single center study to investigate the effect on human intestinal microflora of multiple doses of ceftobiprole treatment administered at 8 hours intervals for 7 consecutive days. Careful investigation of the effect of Ceftobiprole treatment on the intestinal microflora is of importance since alteration of the intestinal microflora balance may facilitate colonization by pathogenic bacteria strains or enable microorganisms already present in the normal microflora to develop resistance. A total of 7 fecal samples will be collected on day 2, 4, 7, 10, 14 and 21 for determination of ceftobiprole concentration in fecal, intestinal microflora pattern and measuring the susceptibility for Ceftobiprole of isolated bacterial strains. A total of 13 plasma samples will be collected on day 1, 4, 7, 10, 14 and 21 for determination of ceftobiprole concentration in plasma. Safety evaluations including physical examination, vital signs, clinical laboratory tests, electrocardiogram and adverse event monitoring will be performed throughout the study. 500 mg ceftobiprole, intravenous infusion over 120 minutes, every 8 hours for 7 consecutive days

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

14 years to 36 years (Adult)

Accepts Healthy Volunteers

No

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

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
Time Frame
Bacterial strains and numbers in feces; Minimum inhibitory concentrations for ceftobiprole for isolated resistant strains
Time Frame: Day 2, 4, 7, 10, 14 and 21
Day 2, 4, 7, 10, 14 and 21

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
Time Frame
Fecal concentration of ceftobiprole
Time Frame: Day 2, 4, 7, 10, 14 and 21
Day 2, 4, 7, 10, 14 and 21
Plasma Concentration of ceftobiprole
Time Frame: Day 1, 4, 7, 10, 14, and 21
Day 1, 4, 7, 10, 14, and 21

Primary Completion (Actual)

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.
