About this study

Official title: Phase II Clinical Trial of Therapeutic Angiogenesis With Mononuclear Cells Autologous Bone Marrow in Patients With Chronic Ischemia Diabetics Critical Limb (CLI) no Revascularization.

The aim of the study is to evaluate the safety and feasibility of autologous bone marrow mononuclear cells autologous administered intra-arterially in the affected limb of diabetic patients with chronic critical ischemia of the lower limbs (CLI) without possibility of revascularization or other therapeutic alternatives.

The trial hypothesis we propose consists of mononuclear cells of bone marrow providing progenitor cells with regenerative capacity and secrete also 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

Read the detailed description

Phase II Clinical Trial, a prospective, multicenter, open, randomized, parallel-group controlled with three dose levels.

The study population will consist of a total of 60 diabetic patients with chronic critical ischemia of one leg (CLI) and no possibility of revascularization. In the experimental group will include a total of 45 patients divided into three dose levels, 15 patients in each level (increasing doses of mononuclear cells of bone marrow evenly) and 15 patients in control group (no cell therapy). Patients will be randomly assigned to either the control group or to any of the three experimental groups in which the dose of mononuclear cells of bone marrowo will be:

  • Group 1(15 patients): no cell therapy.
  • Group 2(15 patients): 1x108 mononuclear cells of bone marrow
  • Gropu 3(15 patients): 5x108 mononuclear cells of bone marrow
  • Group 4(15 patients): 1x109 mononuclear cells of bone marrow The cell therapy medicinal product shall be administered in all cases intraarterially.

Patients were evaluated by clinical, radiological and angiologist methods. This is a randomized controlled trial in which the safety and feasibility of cell therapy medicinal product shall be measured by comparing the response variables after treatment compared to baseline prior to implementation. Secondarily the results obtained are compared with each of the dose groups.

Patients will receive in a concomitant way the drug treatment established by the good practice, so it would certainly be possible that some improvement occurs due to drug treatment.

The primary variable is the improvement in the vascularización of the treated limb determined by clinical, angiologic and angiographic parameters.

It is estimated that the inclusion period lasts between twelve and eighteen months with twelve months follow-up. Therefore the total study duration range between twenty-four and thirty months from the inclusion of the first patient to the end of the follow-up of the last patient included.

Objectives of the study:

  • Main objective: To evaluate the safety and feasibility of mononuclear cells of autologous bone marrow administered intra-arterially in the affected limb of diabetic patients with chronic critical ischemia of the lower limbs without possibility of revascularization or other therapeutic alternatives.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intraarterial infusion of autologous bone marrow cellsOther

    Autologous bone marrow-derived mononuclear cells will be infused by an intraarterial catheter into de ischemic limb. The number of infused cells will be 1x10 E8, 5x10E8 and 1x10 E9 in the low,intermediate and high dose arms respectively

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Intraarterial infusion of autologous bone marrow cells in people with Critical Limb Ischemia (CLI) and Diabetic Foot, run by Andalusian Initiative for Advanced Therapies - Fundación Pública Andaluza Progreso y Salud at 5 sites in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of adverse events (time frame: 24 h, 1,3 ,6 ,9 and 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2016.
