Chronic foot ulcers are a common, severe and expensive complication in patients with diabetes and often causes lower-extremity amputation. The aim of this study is to evaluate the effect of bemiparin as treatment of diabetic foot ulcers.
Foot Ulcer, Diabetic
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator, Outcomes Assessor)

Secondary Outcome Measures:
- incidence of major bleeding and the incidence of adverse events. [ Time Frame: 210 day ] [ Designated as safety issue: Yes ]

- Patients with a history of heparin-induced thrombocytopenia.
- Patients on treatment with anticoagulant therapy at inclusion time or in the past 15 days.
- Patients on treatment with pentoxifiline at inclusion time or in the past 30 days.
- Patients on treatment with systemic corticosteroid or immunosuppressive therapy at inclusion time or in the past 3 months.

- Patients with a life expectancy less than 6 months.
- Patients that cannot complete the scheduled follow-up visits or are not able to complete the study period.
- Patients who are participating in another clinical trial or have done it in the past 30 days.
