About this study

Official title: The Effect of Combination Therapy of Oral Methylene Blue and Platelet-rich Plasma-fibrin Glue in Patients With Non-healing Diabetic Foot Ulcer: a Pilot Study

The aim of this study is to evaluate the chance of non-healing diabetic foot ulcers repair by improving the condition of lack of oxygen or hypoxia in the wound area caused by diabetes using methylene blue along with the use of platelet-rich plasma-fibrin glue as an effective treatment for wound healing.

Read the detailed description

The current study assesses the effects of methylene blue along with the use of platelet-rich plasma-fibrin glue on wound healing in patients with nonhealing diabetic foot ulcers (non-healing DFU). This randomized controlled trial is performed on 20 patients with non-healing DFU. Patients were treated with PRP-FG dressing plus 200 ml of oral methylene blue dissolved in milk(intervention group) or PRP-FG dressing plus placebo (200 ml of milk) (control group) for 4 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The healing rate of the ulcer

    Measurement of wound area with a ruler

    Measured: 4 weeks

  2. Wound Size

    Wound size will be measured with a ruler for length, and width as well as with digital imaging. Wound size will be assessed in digital images taken of the wound.

    Measured: 4 weeks

Secondary outcomes (33)
  1. TcPO2 at baseline and after the intervention

    Transcutaneous oxygen tension (TcpO2) provides information about blood perfusion in the tissue immediately below the skin. (blood pressure, measured in millimeters of mercury (mmHg))

    Measured: 4 weeks

  2. Oxygen saturation at baseline and after the intervention

    Blood must contain a normal concentration of hemoglobin. that hemoglobin must be >95 % saturated with oxygen in arterial blood (sO2(a) >95 %)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Methylene Blue and Methylene Blue and Platelet-Rich Plasma-Fibrin Glue in people with Diabetic Foot Ulcers and Diabetic Wound, run by Mashhad University of Medical Sciences at 1 site in Iran.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 4 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Daryoush Hamidi Alamdari, Ph.D (+98 51 3882 8574, hamidiad@mums.ac.ir), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The healing rate of the ulcer (time frame: 4 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Oct 2023.
