Purpose
Phase II Clinical Trial, a prospective, multicenter, open, randomized, parallel-group controlled with three levels of dose.
The hypothesis of the test we propose is that the mononuclear cells of bone marrow provide progenitor cells with regenerative capacity and besides secrete several angiogenic factors, and their implantation into ischemic tissues with both elements should contribute to angiogenesis and tissue regeneration with recovery of the circulation in the affected limb.

Detailed Description:
The study population will consist of a total of 88 non-diabetic patients with chronic critical ischemia in at least one of their lower limbs and without possibility of revascularization. In the experimental group will be included a total of 66 patients divided into three levels of dose, 22 patients in each level (increasing dose of mononuclear cells from autologous bone marrow) and other 22 patients in control group.
- 22 patients in group 1 will not receive cell therapy, and they will only receive conventional treatment, acting as a control group.
- 22 patients in group 2 will receive 1x108 autologous bone marrow mononuclear cells.
- 22 patients in group 3 will receive 5x108 autologous bone marrow mononuclear cells.
- 22 patients in group 4 will receive 1x109 autologous bone marrow mononuclear cells.
The cell therapy drug will be administered intra-arterially in all cases Patients will be evaluated by clinical, radiological and angiological methods (ankle / brachial pressure index, oximetry, digital arteriography).
Patients will receive concomitant drug treatment established by the good clinical practice, so undoubtedly it could be possible that some improvement occurs due to drug treatment.
It is estimated that the inclusion period is approximately 24 months, and the follow-up of each patient of six months. Therefore the total duration of the study will be about thirty months from the entry of the first patient to the end of the follow-up period of the last patient included.
The primary variable is the improvement in the vascularisation of the treated limb determined by clinical, angiographic and angiologist parameters.
Study objectives :
• Main objective: To evaluate the safety and feasibility of the autotransplantation of autologous bone marrow mononuclear cells administered intra-arterially in non-diabetic patients with critical chronic ischemia of the lower limbs without possibility of either revascularization or other therapeutic alternatives.
Secondary objectives:
- To compare the effect of three increasing dose of mononuclear cells from autologous bone marrow in the recovery of clinical, angiographic angiologist parameters in non-diabetic patients with critical chronic ischemia of lower limbs to a control group that will have been applied to a conventional treatment.
- To analyze complications from regenerative therapy itself, from the route of administration and / or study procedures.
