April 22, 2014 updated by: Tourcoing Hospital

Six- Versus Twelve-Week Therapy for Non-Surgically-Treated Diabetic Foot Osteomyelitis: A Multicenter Open-Label Controlled Randomized Study

The purpose of the study is to compare the efficacy and tolerance of 6- versus 12-week antibiotic therapy in patients with diabetic foot osteomyelitis treated medically.

Study Overview

Status

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

The aim of this randomized multicenter clinical study is to compare the efficacy and tolerance of 6 versus 12-week antibiotic treatment in patients with diabetic foot osteomyelitis treated medically as no equivalent data are currenty available in the literature.

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.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • diabetic patients treated non-surgically (i.e. without amputation or resection of the infected bone) for an osteomyelitis of the foot complicating a neuropathic foot without ischemia of the foot defined as the absence of any pedal pulse. Patients aged of 18 years or more were included if they had type 2 diabetes and osteomyelitis of the foot (i.e.below the ankle).

Exclusion Criteria:

  • Patients with gangrene or who require bone resection or amputation when osteomyelitis of the foot was diagnosed

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
Primary outcome measure was the proportion of patients of each group with remission of diabetic foot osteomyelitis at the end of follow-up.
Time Frame: one year
Remission was defined as the absence of any sign of infection at the initial or a contiguous site, evaluated at least one year after the end of antibiotic treatment (ie at the end of follow-up), with neither a new infectious episode nor the need for orthopedic surgery of the foot at either of these sites during the treatment and follow-up period.
one year

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
tolerance to treatment in each group of patients
Time Frame: 6 or 12 weeks
number of episodes of adverse events attributable to the antibiotic treatment recorded in each group of patients.
6 or 12 weeks

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.

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
