NCT ID: NCT01867190

Last Updated: 2019-02-22

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 24 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-05-31
• Study Completion Date: 2016-03-31

Brief Summary

This study will assess the safety and efficacy of intra-arterial infusion and intramuscular injection of an autologous, bone marrow-derived stem cell preparation (ASCT01) in patients with critical limb ischemia who have exhausted all medical and surgical therapeutic options. The safety and tolerability will be evaluated by regular monitoring of the general physical condition, vital signs, and the occurrence of AE and SAE, respectively. Furthermore, the standard biochemical and blood variables (red and white blood cell counts, Hb, Ht, platelets, sodium, potassium, chloride, calcium, phosphor, ASAT, ALAT, bilirubin, total protein, albumin, AP, cholesterol (LDL,HDL), triglycerides, urea and creatinine, immunoglobulins, HBA1c, C-peptide) will be checked before the treatment as well as 30 and 90 days after the treatment.

Detailed Description

Efficacy will be determined by number of collateral arteries as assessed magnetic resonance angiography at baseline and again at 3 months, rate of major amputation (above the ankle) of the affected limb within 3 months or an unchanged critical limb ischemia of the affected limb after 3 months defined as less than 15% change in tcPO2 or ABI or absolute ankle pressure.Efficacy endpoint is at 3 months. Clinical endpoints and safety will be measured through 12 months.

Eligibility Criteria

Inclusion Criteria

1. Male and Female patients in the age group of 18-80yrs.

2. Established CLI (confirmed by Rutherford 4 to 5) with angiographic evidence of significant infra-inguinal arterial occlusive disease

3. Ankle Brachial Pressure Index (ABI) ≤ 0.6 or the absolute ankle blood pressure < 60 mm Hg or TcPO2<20 mmHg without tissue loss or TcPO2<40 mmHg if there is tissue loss or alternatively toe Brachial Pressure Index (TBI) less 0.5 or the absolute toe blood pressure less than 50 mm Hg

4. No surgical or interventional option for revascularization and no response to best standard care delivered as confirmed by a vascular surgeon and/or physician.

5. No immediate life-threatening complication from CLI which would demand immediate amputation.
