Cardiovascular Clinical Project to Evaluate the Regenerative Capacity of CardioCell in Patients With No-option Critical Limb Ischemia (N-O CLI)
- Registration Number
- NCT03423732
- Lead Sponsor
- John Paul II Hospital, Krakow
- Brief Summary
The main objective of the CIRCULATE project is to compare the clinical outcomes of CardioCell administration in treatment of ischemic damages of cardiovascular system with control group, who will be treated by the administration of placebo during the sham procedure.
- Detailed Description
It is planned to enroll 105 patients into N-O CLI trial with randomization into active (CardioCell) therapy and sham procedure/placebo administration with 2:1 ratio.
The primary research question of this project is to check if the administration of CardioCell could improve the clinical outcomes in patients with N-O CLI.
There are several secondary questions, defined by secondary endpoints, e.g.: if the investigated treatment is possible to administered, if the investigated treatment is safe in each studied indication and way of CardioCell administration, if it is possible to define any selected subgroup in which the treatment results are significantly different than in whole group.

- Females of childbearing potential who does not have a menstrual period confirmed and a negative highly sensitive urine or serum pregnancy test
- Participation in any other clinical research study that has not reached the primary efficacy endpoint or otherwise would interfere with the patient's participation in this project
- Life expectancy < 1 year
- Any concurrent disease or condition that, in the opinion of the investigator, would make the patient unsuitable for participation in the project

- Arm && Interventions
Group Intervention Description Active Group CardioCell Patients randomized to the active treatment group will receive CardioCell consist 30 000 000 cells (suspended in 20 ml of 0.9% NaCl and 5% albumin); 15 000 000 via common femoral artery injection and 15 000 000 via intramuscular injections above the knee (ATK, 6 injection sites) and below the knee (BTK, 6 injection sites). Control Group Placebos Patients randomized to the placebo group will receive Placebos consist 0.9% NaCl and 5% albumin injections (in the same volumes as CardioCell) injections in the same manner.
- Primary Outcome Measures
Name Time Method Change in pain-free walking distance 6 month FU Change in pain-free walking distance (6M FU vs index evaluation) between two groups (active vs placebo therapy).
- Secondary Outcome Measures
Name Time Method Amputation-free survival period 6 month and 1 year FU. Amputation-free survival period evaluation of treated leg at 6 month and 1 year FU.
Ulcer-free survival 6 month and 1 year FU Ulcer-free survival (in patients without ulceration at baseline evaluation) of treated leg in period evaluation at 6 month and 1 year FU.
Ulcer-extension free survival 6 month and 1 year FU Ulcer-extension free survival (in patients with ulceration in the beginning of the trial) of treated leg in period evaluation at 6 month and 1 year FU.
Change in tissue oxygen/CO2 tension 45 days, 3 month, 6 month and 1 year FU Change in tissue oxygen/CO2 tension, assessed by NIRS method at each trial evaluation point.
An improvement of tissue perfusion 45 days, 3 month, 6 month and 1 year FU An improvement of tissue perfusion assessed in MRI at each trial evaluation point.
Change in transcutaneous pressure of O2 45 days, 3 month, 6 month and 1 year FU Change in transcutaneous pressure of O2 (tcpO2) between two groups (active vs placebo therapy) at each trial evaluation point.
Change in ABI score 45 days, 3 month, 6 month and 1 year FU Change in ABI score at each trial evaluation point.
The ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm and is calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressure in the arm.
An ABI between and including 0.9 and 1.2 is considered normal, while a lesser than 0.9 indicates peripheral arterial disease. An ABI value of 1.3 or greater is also considered abnormal, and suggests calcification of the walls of the arteries and incompressible vessels. ABI score progression towards the normal range is considered as a better outcome.Quality of life improvement, assessed by SF-36 questionnaire 45 days, 3 month, 6 month and 1 year FU Quality of life improvement, assessed by SF-36 questionnaire or other dedicated for investigated population at each trial evaluation point.
