Safety and Efficacy of Autologous Bone Marrow Mononuclear Cells in Patients With Severe Critical Limb Ischemia

Critical Limb Ischemia Clinical Trial

Official title:
To Study and Demonstrate the Safety and Efficacy of RES-Q Prepared Bone Marrow Mononuclear Cells Injected Into Ischemic Tissue of Patients With Non-Reconstructable Critical Limb Ischemia (CLI).

Clinical Trial Summary

The purpose of this study is to evaluate the safety and efficacy of the concentrated autologous bone marrow derived stem cells for the treatment of Critical Limb Ischemia patients.

Clinical Trial Description

A total of 15 patients suffering from end stage IV and V Rutherford /CLI in whom all previous therapeutic strategies failed (e.g. surgical revascularization) will be selected and undergo local transplantation of autologous BMMNCs. Conventional treatments include angioplasty and /or bypass to remove blood vessel blockage for restoring blood supply, along with prescribed medicines that aid in ulcer recovery and wound healing and debridement of damaged/infected tissue. Amputation is inevitable in many cases because some blood capillaries cannot be corrected and restenosis of vessels is very common. Cell therapies with mononuclear cells from patients own bone marrow is promising because these stem cells are capable of stimulating and regenerating capillaries and blood vessels (neovascularization).

This is a Phase Ib (feasibility study), prospective, non randomized and open labeled study aimed to find out the safety and efficacy of intramuscular autologous bone marrow mononuclear cells implantation in patients with chronic critical limb ischemia.

The efficacy/safety of this therapy will be assessed by using several endpoints such as (a) prevention of amputation, (b) wound healing and (c) degree of angiogenesis. In order to assess the limb ischemia, the measurements will be performed at pre- and post transplantation at a variety of time intervals. The measurements include: ABI-ankle brachial index, Transcutaneous partial pressure of Oxygen (TcPO2), 6 min walk test, Rest pain and intermittent Claudication assessment, Healing of ulcers/ wounds and angiography of the affected limb. ;
