Autologous Bone Marrow-derived Mononuclear Cells for Therapeutic Arteriogenesis in Patients With Limb Ischemia (ABC)

Descrizione dettagliata
Although the safety and beneficial effects of intramuscular transplantation of bone marrow derived mononuclear cells procedure appear well documented, a number of critical question regarding application of BM-MNC for peripheral vascular disease remain to be answered. First, although the original study has been partially performed as semi-blinded study (patients with double sided claudication were recruited and blindly treated with BM-MNC in one leg and peripheral blood injections in the other leg), this approach does exclude a placebo effect. Second, although patients with mild diabetes were included in the protocol, the results for diabetic patients were not analyzed separately. Diabetic disease is characterized by monocyte and endothelial progenitor cell dysfunction and it is still unclear whether this approach is also effective in diabetic patients. Third, although six-month results are reported long-term efficacy has not been established yet.
To address these issues, the investigators now propose confirm and extend the findings from open studies in a randomized double-blind study in patients with severe claudication or critical leg ischemia and pay special attention to the influence of diabetic disease on the outcome of the study and to the possible pro-atherogenic/ pro-inflammatory effects of BM-MNC injections.

Descrizione
Inclusion Criteria:
- persistent (>3 months) disabling claudication (Fontaine's stages IIb or Rutherford's categories 3, viz. pain free walking distance less than 100 meter) despite optimal therapy or critical limb ischemia (Fontaine's stages III/IV or Rutherford's categories 4-6)
- ineligibility for angioplasty or bypass procedures
- male of female, >18 years old
- life expectancy > 1 year
- written informed consent
Exclusion Criteria:
- candidates for angioplasty or bypass procedures
- inability to undergo bone marrow harvesting
- any condition in the affected limb that is anticipated to require surgical intervention in the first weeks after BM-MNC treatment
- life threatening co-morbidity
- poorly controlled diabetes (HbA1C > 10%)
- active malignancy in the 5 years prior to treatment
- INR >1.5 at the time of bone-marrow harvest
- bleeding diathesis
- inability to undergo arterial catheterization
- inability to follow the protocol and to comply with the follow up requirements
- any other conditions that, in the opinion of the investigators, could interfere with the therapy or could pose a significant threat to the subject if the investigational therapy was to be initiated
