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

Arms and Interventions

Participant Group / Arm

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

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.
EXPERIMENTAL: Ultrasounds once a week
Patients will undergo the application of ultrasound therapy with a frequency of once a week.
Procedure: Ultrasound Debridement
Ultrasounds debridement is performed using an SONOCA 185 device (Söring GmbH, Germany). The ultrasounds device generates an ultrasound low frequency of 25kHz and is equipped with three instruments with different sonotrode shapes. The choice of sonotrode depends on wound depth. The ultrasounds instrument piezoelectrically transforms the electrical energy delivered from the ultrasound device into mechanical oscillations in the sonotrode tip.
EXPERIMENTAL: Ultrasounds once every two weeks
Patients will undergo the application of ultrasound therapy with a frequency of once every two weeks.

ACTIVE_COMPARATOR: Standard of care
Patients will be treated using the conventional treatment established by the protocol of the Diabetic Foot Unit of the University Podiatry Clinic of Complutense University of Madrid.
Procedure: Conventional Treatment
Conventional Treatment based on international guidelines for diabetic foot

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
Healing Rate
Time Frame: 12 weeks
Total epithelialization of the wound.
12 weeks
Healing Time
Time Frame: 12 weeks
Time from the inclusion of the wound in the study until its total epithelialization.
12 weeks
Wound Size
Time Frame: 12 weeks
Planimetric measurements of wound size will be made using Visitrak (Smith & Nephew, Hull, UK).
12 weeks

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
Wound Conditions
Time Frame: 12 weeks
The wound bed tissue will be evaluated for the presence, quality and consistency of the granulation tissue using a validated wound scoring system, with scores ranging from a minimum of zero points to a maximum of seven points (Wollina Score).
12 weeks
Transcutaneous oxygen pressure (TcPO2)
Time Frame: baseline and week 7
Two measurements will be made, one at the initial visit and the other at the final visit, and possible variations will be assessed.
baseline and week 7
Pain intensity
Time Frame: 12 weeks
It will be assessed using a numerical scale of pain that receives values between zero and ten, understanding zero as the absence of pain and ten as the maximum pain bearable by the patient
12 weeks
Health-related quality of life
Time Frame: baseline and 12 week
It will be assessed using the SF-36 health-related quality of life questionnaire at the beginning and end of the study. This questionnaire receives values between zero and one hundred so that the higher the score, the better the patient's health status.
baseline and 12 week

Primary Completion (ANTICIPATED)

Primary Completion
