Summary

This phase 2 trial tests whether photobiomodulation, a type of light therapy, can improve healing of foot ulcers in people with diabetes. Researchers will compare standard wound care alone against standard care plus light therapy applied to the ulcer and to blood vessels. The study includes 20 adults with type 1 or type 2 diabetes who have a chronic foot ulcer. The main goal is to see if the treatment reduces the wound area over 12 weeks, with additional checks on healing scores, skin temperature, and blood flow.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Photobiomodulation (light therapy) applied to the skin over the ulcer and to blood vessels, compared with a placebo light treatment and standard wound care.
What this could lead to
If it works, this could offer a non-invasive way to speed up healing of diabetic foot ulcers, potentially reducing the risk of amputation and improving quality of life.
What could go wrong
This is a small early-stage trial with only 20 participants, so results may not apply to everyone. Light therapy may not heal ulcers faster than standard care, and the treatment requires multiple sessions over months.

Inclusion Criteria: * Medical diagnosis of Diabetes Mellitus type 1 or 2; * Presence of a foot ulcer with duration ≥ 4 weeks, characterizing a chronic ulcer; * Age ≥ 18 years; * Ankle-brachial index compatible with adequate perfusion, allowing for the safe conduct of treatment; * Wagner Grade I or Wagner Grade II classification of DM ulcer * Ability to understand the objectives of the study and signature of the ICF (Informed Consent Form). - Exclusion Criteria: * Having more than one ulcer to be treated, regardless of etiology; * Presence of hematological diseases that may interfere with peripheral blood analysis, such as: hemolytic anemias, hemoglobinopathies (sickle cell anemia), leukemias, lymphomas, multiple myeloma, or other blood dyscrasias that may significantly interfere with cell morphology or peripheral blood analysis; * Active systemic infection at the time of enrollment; * Active neoplasia undergoing treatment or under investigation; * Use of immunosuppressants or corticosteroids; * Pregnant or breastfeeding women; * Use of photosensitizing medications; * Allergy or sensitivity to any of the study interventions; * Clinical signs of infection, necrosis, devitalized tissue, or wound colonization. * Acute clinical conditions that contraindicate participation, whether related or unrelated to DM.
