Main objective

Scope: Others, Pharmacoeconomic, Efficacy, Therapy, Safety

The primary aim of this trial is to evaluate time to healing. This means to evaluate the efficiency of local antimicrobial agents to bring about complete healing of DFU, diabetic foot ulcer.

Secondary objectives 5

  1. To evaluate if treatment with HOCl and PHMB in treating DFU differ with respect to proportion of DFU that heals within 12 weeks of treatment.
  2. To evaluate if treatment with HOCl and PHMB in treating DFU differ with respect to the size of the DFU´s surface area over 24 weeks of treatment.
  3. To evaluate if treatment with HOCl and PHMB in treating DFU differ with respect to the depth of the DFU over 24 weeks of treatment.
  4. To evaluate if treatment with HOCl and PHMB in treating DFU differ with respect to use of antibiotics over 24 weeks of treatment.
  5. To evaluate if treatment with HOCl and PHMB in treating DFU differ with respect to quality of life over 24 weeks of treatment using the EQ-5D questionnaire.

Inclusion criteria 5

  1. Written and verbal informed consent given before trial-related activities

  4. Ulcer surface area ≥ 9 mm2
  5. Age 18 years old or older

Exclusion criteria 15

  1. Persons in need of intensive care or dialysis.
  2. Diabetes of MOODY type.
  3. Current known pregnancy or planned pregnancy during the next 26 weeks by asking the participant.
  4. For participation in the sub study of 40 patients taking biopsies the DFU shall not be close to a joint, have direct skeletal contact or risk that such an appear and the DFU should not be ground with granular healing tissue.
  5. Participation in another trial evaluating any treatment.
  6. Other reasons judged by the investigator that the patient is unsuitable for participation in the study.
  7. Persons in need of vascular intervention, critically impaired peripheral circulation (toe pressure < 30 mmHg).
  8. Current treatment of malignancy.
  9. Event of myocardial infarction or stroke during the last 4 weeks.
  10. Debut of atrial fibrillation or heart failure (ejection fraction <40 %) during the last 4 weeks.
  11. Treatment with corticosteroids of a dose corresponding to 50 mg Prednisolone or higher.
  12. Severe wound infection according to the International Working Group of the Diabetic Foot comprising at least 2 of the following signs: body temperature>38°C or <36°C, heart rate >90 beats/minute, respiration rate >20/minute, LPK>12 x 10^9
  13. Planned changed residence within the next 26 weeks requiring change of clinic for wound treatment during the follow-up time.
  14. Age <18 years old.
  15. If the toe or foot where the DFU is located likely needs amputation in close future or will undergo a spontaneous amputation or need judgement regarding this risk of amputation by further specialist (o.e. the DFU will not be possible to evaluate regarding healing effects)

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The primary endpoint variable is difference in the time from baseline (randomization) to healing for patients randomized to treatment with HOCl and PHMB evaluated over 24 weeks of treatment measured as hazard ratio.

Secondary endpoints 5

  1. Proportion healed DFUs in HOCl group versus PHMB group at week 12.
  2. The difference in the change of the surface area of the DFU for patients treated with HOCl versus PHMB from baseline (randomization) over 24 weeks.
  3. The difference in the change of the depth of the DFU for patients treated with HOCl versus PHMB from baseline (randomization) to week 24.
  4. Difference in the mean number of days of antibiotic treatment for patients treated with HOCl versus PHMB from baseline (randomization) to week 24.
  5. Difference in the change of quality of life using the EQ5-D questionnaire for patients treated with HOCl versus PHMB from baseline (randomization) to week 24.
