Efficacy of LL-37 Cream on Bacteria Colonization, Inflammation Response and Healing Rate of Diabetic Foot Ulcers

September 22, 2019 updated by: Eliza Miranda, MD, Fakultas Kedokteran Universitas Indonesia

The Efficacy of LL-37 Cream on Aerobic Bacteria Colonization Pattern, Inflammation Response: Interleukin 1α (IL-1α) and Tumor Necrosis Factor α (TNF-α), and Healing Rate of Diabetic Foot Ulcers

Diabetic foot ulcer (DFU) is a common complication of diabetes with global prevalence of 6.3%. Treatment of diabetic foot ulcer (DFU) is challenging with disappointing outcome. Wound debridement, infection control, pressure relief and revascularization are main pillars of DFU management. Various substances and modalities are being investigated for their potential effects in treating DFU, one of which is LL-37.

In this randomized, controlled trial, 40 patients with uncomplicated DFU will be enrolled. Patients are randomly assigned to undergo twice a week treatment with 0.5 mg/mL LL-37 cream (treatment group) or placebo cream (control group) for 4 weeks in addition to standard wound care. The primary outcomes are the healing rate measured by wound area and granulation index and changes in patterns of aerobic bacteria colonization during the 4-week study duration and changes in concentrations of IL-α and TNF-α from fluid collected from DFU on the end of the second and third week of study compared to baseline.

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.
