Brief Summary:

The goal of this clinical trial is to test a topical drug in patients with mild infections of their diabetic foot ulcer. The main questions it aims to answer are:

What strength does the drug need to be in order to make the infection better? How frequently does the drug need to be applied in order to make the infection better? Participants will be asked to apply the medicine on their foot ulcer twice a day for 2 weeks and remain off of that foot during that time.

Participants will receive the medication either once a day or twice a day, in either a 5% or 10% gel, or placebo.

Researchers will compare the 5% and 10% gels to placebo to see if the infection improves.

  3. Safety [ Time Frame: Day 0 to Day 28 ]
    Number of AEs (overall and those assessed by the investigators as possibly, probably and definitely related to the study drug) and SAEs per patient and cohort and clinically relevant changes in physical examination, vital signs, laboratory and/or ECG measurements at the defined timepoints compared to baseline

  4. Safety [ Time Frame: Day 0 to Day 28 ]
    Change in parameters indicative of skin irritation and/or skin sensitization compared to baseline

  5. Pharmacokinetics [ Time Frame: Day 0 to Day 13 ]
    Maximum concentration in the first 20 patients sampled for PK across all dosing groups after initial and repeated dosing


Other Outcome Measures:
  1. Wound healing [ Time Frame: Day 0 to Day 28 ]
    Percentage area reduction of wound size at Day 7, Day 14, and Day 28 compared to baseline

  2. Wound healing [ Time Frame: Day 0 to Day 28 ]
    Change in the 5-component clinical signs DFI score at all timepoints compared to baseline

  3. Wound healing [ Time Frame: Day 0 to Day 28 ]
    Change in the overall DFI score at all timepoints compared to baseline
