Last verified: September 2007
The purpose of this study is to evaluate whether a treatment with urokinase (500 000 or 1 000 000 IU) can lead to ulcer-healing, lower rate of major amputation, and prolonged survival in patients with diabetic foot syndrome.

Condition Intervention Phase
Diabetic Foot Arterial Occlusive Disease Ischemia Drug: Urokinase Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase II Study of Urokinase Therapy for Treatment of Angiopathic or Angioneuropathic Diabetic Foot Syndrome

Further study details as provided by medac GmbH:

Primary Outcome Measures:
  • Number of patients being alive, having no major amputation and healed ulceration [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • Each of overall survival, major amputation rate, survival free of major amputation rate, rate of ulcer healing, and safety [ Time Frame: 12 months ]

Enrollment: 77
Study Start Date: February 2002
Study Completion Date: December 2006
Arms Assigned Interventions
Experimental: 1
Interventional group
Drug: Urokinase

Daily intravenous application of urokinase over 30 minutes


If plasma fibrinogen is > 2,5g/l application of 1 000 000 IU Urokinase If plasma fibrinogen is < 2,5g/l application of 500 000 IU Urokinase If plasma fibrinogen is < 1,6g/l treatment must be stopped and continued after rising up to >2g/l

Detailed Description:
Patients with diabetic foot ulceration and critical limb ischemia have a high risk of major amputation especially if limbs cannot be revascularized. Urokinase is effective in improving the microcirculation in critical limb ischemia by lowering fibrinogen and might improve outcomes. There are however no data on the efficacy and safety of urokinase treatment in terms of survival free of major amputation, ulcer healing and the rate of minor and major bleeding. Therefore this trial is conducted to investigate the effect of urokinase treatment on these parameters.
